High fructose corn syrup - Apiculture (Bee Keeping)
In the United States, HFCS has become a sucrose replacement for honey bees. In 2009, a study by Leblanc et al. found that at temperatures above HFCS rapidly forms hydroxymethylfurfural, which is toxic to the honey bees being fed HFCS. In 2012, a study by Chensheng Lu et al. found symptoms of colony collapse disorder (CCD) in beehives fed HFCS that the researchers laced with levels of a pesticide hypothesized to have been present in HFCS feed back in 2006.

Intel APIC Architecture
The Intel 'APIC Architecture' is a system of Advanced Programmable Interrupt Controller|advanced programmable interrupt controllers (APICs) designed by Intel for use in Symmetric multiprocessing|symmetric multiprocessor (SMP) computer systems. It was originally implemented by the Intel 82093AA and 82489DX, and is found in most x86 SMP motherboards. It is one of several attempts to solve interrupt routing efficiency issues in multiprocessor computer systems.
6
Intel APIC Architecture - Overview
There are two components in the Intel APIC system, the local APIC (LAPIC) and the I/O APIC. There is one LAPIC in each CPU in the system. There is typically one I/O APIC for each peripheral bus in the system. In original system designs, LAPICs and I/O APICs were connected by a dedicated APIC bus. Newer systems use the system bus for communication between all APIC components.
7
Intel APIC Architecture - Local APICs
LAPICs manage all external interrupts for some specific processor in an SMP system. In addition, it is able to accept and generate inter-processor interrupts (IPIs) between LAPICs. LAPICs may support up to 224 usable interrupt vectors from an I/O APIC. Vectors numbers 0 to 31, out of 0 to 255, are reserved for exception handling by x86 processors.
8
Intel APIC Architecture - I/O APICs
I/O APICs contain a redirection table, which is used to route the interrupts it receives from peripheral buses to one or more local APICs.
9
Intel APIC Architecture - Problems
On older operating systems, people often had to disable the I/O and local APICs
10
Intel APIC Architecture - More information
More information on the Intel APIC Architecture can be found in the Intel 64 and IA-32 [ Intel Architecture Software Developer’s Manual], Volume 3A: System Programming Guide, Part 1, Chapter 10, freely available on the Intel website.
11
X2APIC The 'x2APIC' architecture provides backward compatibility to the Intel APIC Architecture/xAPIC architecture (introduced with the Pentium/P6 (microarchitecture)|P6 and the Pentium 4 generations respectively) and forward extendability for future Intel platforms.
12
X2APIC - Overview The major improvements of the x2apic concern the number of supported CPUs and performance of the interface.
13
X2APIC - Overview The x2APIC now uses 32 bits to address CPUs, allowing to address up to 2^32-1 CPUs using the physical destination mode. The logical destination mode now works differently and introduces clusters. Using this mode, one can address up to 2^20-16 processors.
14
X2APIC - Overview The improved interface reduces the number of needed APIC register access for sending Inter-processor interrupts.
15
X2APIC - More information
More information on the Intel x2APIC Architecture can be found in the Intel 64 and IA-32 [ Architectures Software Developer's Manuals], Intel 64 Architecture x2APIC Specification, freely available on the Intel website.

Mineral trioxide aggregate - Root-end Filling after Apicoectomy
In root canal therapy where an apical infection is persistent, an apicoectomy may be required.
17
Mineral trioxide aggregate - Root-end Filling after Apicoectomy
There were several different materials such as amalgam, reinforced zinc oxide eugenol cements (intrim restorative material - IRM, super ethoxy benzonic acid [EBA], glass ionomer cement and composite resin for root-end filling after apicoectomy
18
Mineral trioxide aggregate - Root-end Filling after Apicoectomy
1. Glass ionomer cement: It is based on alumino-silicate based bioceramic material. Most cytotoxicity is caused by polyacrylic acid. So current GIC as root-end filling material is reducing the cytotoxic acclerator's concentration. - calcium alumino-silicate - MTA (calcium alumino-silicate) + GIC (alumino-silicate), calcium reinforced glass ionomer cement is developed. It's a promising material.
19

4. Calcium aluminate bioceramic material - (alumina cement in minerals, calcium aluminate cements in bioceramics)
23
Mineral trioxide aggregate - Root-end Filling after Apicoectomy
Alumina is an initial fast setting element and high compressive strength. It has been used as dental products as luting agent. Calcium aluminate cement (bioceramic) has been developed for dental products and root-end filling material.
24
Mineral trioxide aggregate - Root-end Filling after Apicoectomy
These newly developed root-end filling materials are based on bioceramic, chemically bonded ceramic, not by mineral (ceramic in nature) like MTA. Even if mineral shows higher biocompatibility, minerals have potential toxic heavy metals in material. Bioceramic or Bio material|bioMaterial is used for medical and dental products. Biomaterial|BioMaterials can reduce the issues on discoloration and toxic heavy metals' presence initially.

CAPICOM 'CAPICOM' is a discontinued ActiveX control created by Microsoft to help expose a select set of Microsoft Cryptographic Application Programming Interface (CryptoAPI) functions through Microsoft Component Object Model (COM). It was intended to enable every environment that supports ActiveX to use Microsoft Cryptographic technologies, including web pages that are opened with Microsoft Internet Explorer or any other web browser that supports ActiveX.
26
CAPICOM CAPICOM can be used to digitally sign data, inspect, verify and display their digital signature and/or digital certificate, add or remove certificates to or from the certificate stores, and finally, to encrypt or decrypt data.
27
CAPICOM CAPICOM Version , the latest and last version of CAPICOM, is officially supported on Windows Vista. However, Microsoft has announced that CAPICOM is discontinued and is no longer being developed. Microsoft suggests replacing CAPICOM with .NET Framework's X509 Cryptographic Classes and a number of other alternatives.

Meristem - Apical meristems
Apical meristems are very small, compared to the cylinder-shaped lateral meristems (see 'Secondary Meristems' below).
77
Meristem - Apical meristems
Some Arctic plants have an apical meristem in the lower/middle parts of the plant
78
Meristem - Shoot apical meristems
The source of all above-ground organs. Cells at the shoot apical meristem summit serve as stem cells to the surrounding peripheral region, where they proliferate rapidly and are incorporated into differentiating leaf or flower primordia.
79
Meristem - Shoot apical meristems
The shoot apical meristem consists of 4 distinct cell groups:
80
Meristem - Shoot apical meristems
* The immediate daughter cells of the stem cells
81
Meristem - Shoot apical meristems
* A subjacent organising centre
82
Meristem - Shoot apical meristems
* Founder cells for organ initiation in surrounding regions
83
Meristem - Shoot apical meristems
In Arabidopsis thaliana, 3 interacting CLAVATA genes are required to regulate the size of the stem cell reservoir in the shoot apical meristem by controlling the rate of cell division.Fletcher, J
84
Meristem - Shoot apical meristems
CLV1 has been shown to interact with several cytoplasmic proteins that are most likely involved in Signal transduction|downstream signalling

(1998) Control of Meristem Development by CLAVATA1 Receptor Kinase and Kinase-Associated Protein Phosphatase Interactions Plant Physiology 117: KAPP is thought to act as a negative regulator of CLV1 by dephosphorylating it.
86
Meristem - Shoot apical meristems
Another important gene in plant meristem maintenance is WUSCHEL (shortened to WUS), which is a target of CLV signalling.Mayer, K. F. X et al. (1998) Role of WUSCHEL in Regulating Stem Cell Fate
87
Meristem - Shoot apical meristems
in the Arabidopsis Shoot Meristem Cell, Vol. 95, 805–815 WUS is expressed in the cells below the stem cells of the meristem and its presence prevents the Cellular differentiation|differentiation of the stem cells. CLV1 acts to promote cellular differentiation by repressing WUS activity outside of the central zone containing the stem cells. STM also acts to prevent the differentiation of stem cells by repressing the expression of Myb genes that are involved in cellular differentiation.

Meristem - Root apical meristems
DOI: /S (10)91003-X It is covered by the root cap, which protects the apical meristem from the rocks, dirt and pathogens
89
Meristem - Apical dominance
Often several branches will exhibit this behaviour after the removal of apical meristem, leading to a bushy growth.
90
Meristem - Apical dominance
The mechanism of apical dominance is based on the plant hormone auxin. It is produced in the apical meristem and transported towards the roots in the vascular cambium|cambium. If apical dominance is complete, it prevents any branches from forming as long as the apical meristem is active. If the dominance is incomplete, side branches will develop.
91
Meristem - Apical dominance
Recent investigations into apical dominance and the control of branching have revealed a new plant hormone family termed strigolactones. These compounds were previously known to be involved in seed germination and communication with mycorrhizal fungi and are now shown to be involved in inhibition of branching.

Apicius 'Apicius' is a collection of Roman Empire|Roman cookery recipes, usually thought to have been compiled in the late 4th or early 5th century AD and written in a language that is in many ways closer to Vulgar Latin|Vulgar than to Classical Latin.
96
Apicius The name Apicius had long been associated with excessively refined love of food, from the habits of an early bearer of the name, Marcus Gavius Apicius, a Roman gourmet and lover of refined luxury who lived sometime in the 1st century AD, during the reign of Tiberius. He is sometimes erroneously asserted to be the author of the book that is Pseudepigrapha|pseudepigraphically attributed to him.
97
Apicius Apicius is a text to be used in the kitchen. In the earliest printed editions, it was most usually given the overall title De re coquinaria (On the Subject of Cooking) and attributed to an otherwise unknown Caelius Apicius, an invention based on the fact that one of the two manuscripts is headed with the words API CAE.
98
Apicius - Organization
The text is organized in ten books, in an arrangement similar to that of a modern cookbook:The Roman Cookery Book, trans. Flower and Rosenbaum, p. 7.

103
Apicius - Alternative editions
Either some text was lost between the time the excerpt was made and the time the manuscripts were written, or there never was a standard Apicius text because the contents changed over time as adapted by readers
104
Apicius - Alternative editions
Once manuscripts surfaced, there were two early printed editions of Apicius, in Milan (1498)Under the title In re quoquinaria. and Venice (1500). Four more editions in the next four decades reflect the appeal of Apicius. In the long-standard edition of C.T.Schuch (Heidelberg, 1867), the editor added some recipes from the Vinidarius manuscript.
105
Apicius - Alternative editions
Between 1498 (the date of the first printed edition) and 1936 (the date of Joseph Dommers Vehling's translation and bibliography of Apicius), there were 14 editions of the Latin text (plus one possibly apocryphal edition). The work was not widely translated, however; the first translation was into Italian language|Italian, in 1852, followed in the 20th century by two translations into German language|German and French language|French.
106
Apicius - Alternative editions
Vehling made the first translation of the book into English language|English under the title Cookery and Dining in Imperial Rome. It was published in 1936 and is still in print, having been reprinted in 1977 by Dover Publications. It is now of historical interest only, since Vehling's knowledge of Latin was not always adequate for the difficult task of translation, and several later and more reliable translations now exist.

Carapichea ipecacuanha
'Carapichea ipecacuanha' is a species of flowering plant in the Rubiaceae family (biology)|family. It is native to Costa Rica, Nicaragua, Panama, Colombia, Brazil. Its common name, 'ipecacuanha' (), is derived from the Tupi language|Tupi ipega'kwãi, or road-side sick-making plant. The plant has been discussed under a variety of synonym (botany)|synonyms over the years by various botany|botanists. The roots were used to make syrup of ipecac, a powerful emetic.
165
Carapichea ipecacuanha
The part of ipecacuanha used in medicine is the root, which is simple or divided into a few branches, flexuous, and is composed of rings of various size, somewhat fleshy when fresh, and appearing as if closely strung on a central woody cord. The different kinds known in commerce (gray, red, brown) are all produced by the same plant, the differences arising from the age of the plant, the mode of drying, etc. Various other plants are used as substitutes for it.

APICA 'SDB-001' ('2NE1', 'APICA', 'N-(1-adamantyl)-1-pentyl-1H-indole-3-carboxamide') is a drug that acts as a potent agonist for the cannabinoid receptors
180
Apical consonant An 'apical consonant' is a Phone (phonetics)|phone (speech sound) produced by obstructing the air passage with the tip of the tongue. This contrasts with laminal consonants, which are produced by creating an obstruction with the blade of the tongue (which is just behind the tip).
181
Apical consonant This is not a very common distinction, and typically applied only to fricatives and affricates. Thus many varieties of the English language have either apical or laminal pairs of [t]/[d]. However, some varieties of Arabic, including Hadhrami Arabic, realizes [t] as laminal but [d] as apical.
182
Apical consonant A distinction between apical and laminal is common in Australian languages for the nasals, plosives and usually also the lateral approximants.

Killer bee - Impact on existing apiculture
As such, despite all the negatives, it is possible that the Africanized honey bee might actually end up being a boon to the apiculture industry.
184
Apicomplexa Diseases caused by apicomplexan organisms include, but are not limited to:
185
Apicomplexa The name of the taxon Apicomplexa is derived from two Latin words — apex (top) and complexus (infolds) — and refers to a set of organelles in the sporozoite. The older taxon 'Sporozoa' was created by Schrevel in 1971 and grouped the Apicomplexa together with the Ascetosporea, Microsporidia and Myxosporida. This grouping is no longer regarded as biologically valid and its use is discouraged.
186
Apicomplexa - Phylogenetic relations
This has rarely been studied at the subclass level. Morrison using molecular date has shown that the haemosporidia are related to the gregarines and that the piroplasms and coccidians are sister groups. Other studies suggest that the haemosporidia and the piroplasma appear to be sister clades and are more closely related to the coccidians than to the gregarines.
187
Apicomplexa - Phylogenetic relations
Transposons appear to be rare in this phylum but have been identified in the genera Ascogregarina and Eimeria.
188
Apicomplexa - General morphological features
All members of this phylum have an infectious stage — the sporozoite — which possess three distinct structures in an apical complex. The apical complex consists of a set of spirally arranged microtubules (the conoid), a secretory body (the rhoptry) and one or more polar rings. Additional slender electron-dense secretory bodies (micronemes) surrounded by one or two polar rings may also be present. It is this structure that gives the phylum its name.
189
Apicomplexa - General morphological features
A further group of spherical organelles are distributed throughout the cell rather than being localized at the apical complex and are known as the dense granules. These typically have a mean diameter of about 0.7 micrometers. Secretion of the dense-granule content takes place after parasite invasion and localization within the parasitophorous vacuole and persists for several minutes.
190
Apicomplexa - General morphological features
Other morphological findings that are common to all members of this phylum include:
191
Apicomplexa - General morphological features
*The nucleus (cell)|nucleus is haploid.
192
Apicomplexa - General morphological features
*Flagellae are found only in the motile gamete. These are posteriorly directed and vary in number (usually one to three).
193
Apicomplexa - General morphological features
*Basal body|Basal bodies are present. Although hemosporidians and piroplasmids have normal triplets of microtubules in their basal bodies and coccidians and gregarines have 9 singlets.
194
Apicomplexa - General morphological features
*The mitochondria have tubular cristae.
195
Apicomplexa - General morphological features
*A Golgi apparatus is present.
196
Apicomplexa - General morphological features
*Centrioles, chloroplasts, ejectile organelles and inclusions are absent.
197
Apicomplexa - General morphological features
*Colourless plastids are present in some species.
198
Apicomplexa - General morphological features
*The cell is surrounded by a pellicle (biology)|pellicle of three membrane layers (the alveolar structure) penetrated by micropores.
199
Apicomplexa - General morphological features
*Mitosis: usually closed with an intranuclear spindle; in some species it is open at the poles
200
Apicomplexa - General morphological features
*Cell division: usually by schizogony
201
Apicomplexa - General morphological features
Other features common to this phylum are a lack of cilia, sexual reproduction, use of micropores for feeding, movement by body flexion or gliding and the production of oocysts containing sporozoites as the infective form.
202
Apicomplexa - General features
Within this phylum there are three groups — coccidians, gregarines and haemosporidians. The coccidians and gregarines appear to be relatively closely related.
203
Apicomplexa - General features
Perkinsus while once considered a member of this phylum has been moved to a new phylum — Perkinsozoa.
204
Apicomplexa - Gregarines
At some point in the apicomplexan life cycle, gametocytes are formed
205
Apicomplexa - Coccidians
In general, coccidians are parasites of vertebrates. Like gregarines, they are commonly parasites of the epithelial cells of the gut but may infect other tissues.
206
Apicomplexa - Coccidians
The coccidian lifecycle involves merogony, gametogony and sporogony
207
Apicomplexa - Coccidians
The main difference between the coccidians and the gregarines is in the gamonts. In the coccida these are small, intracellular and without epimerites or mucrons. In the gregarines these are large, extracellular and possess epimerites or mucrons.
208
Apicomplexa - Coccidians
A second difference between the coccidia and the gregarines also lies in the gamonts. In the coccidia a single gamonts becomes a macrogametocyte, whereas in the gregarines the gamonts give rise to multiple gametocytes.
209
Apicomplexa - Haemosporidia
The Haemosporidians have more complex lifecycles that alternate between an arthropod and a vertebrate host
210
Apicomplexa - Evolution
All members of this phylum are parasitic and evolved from a free-living ancestor. It is presumed that this lifestyle evolved at the time of the divergence of dinoflagellates and apicomplexans. Further evolution of this phylum has been estimated to have occurred ~. The oldest extant clade is thought to be the archigregarines.
211
Apicomplexa - Evolution
Many Coccidiomorpha have an intermediate host as well as a primary host, and the evolution of hosts proceeded in different ways and at different times in these groups
212
Apicomplexa - Evolution
Similar strategies to increase the likelihood of transmission have evolved in multiple genera. Polyenergid oocysts and tissue cysts are found in representatives of the orders Protococcidiorida and Eimeriida. Hypnozoites are found in Karyolysus lacerate and most species of Plasmodium; transovarial transmission of parasites occurs in lifecycles of Karyolysus and Babesia.
213
Apicomplexa - Evolution
Horizontal gene transfer appears to have occurred early on in this phylum's evolution with the transfer of a histone H4 lysine 20 (H4K20) Histone#Chromatin regulation|modifier, Set8, from an animal host to the ancestor of apicomplexans. A second gene — H3K36 methyltransferase (Ashr3 in plants) — may have also be horizontally transferred.
214
Apicomplexa - Life cycle
There are many variations on this basic pattern, however, and many Apicomplexa have more than one host.
215
Apicomplexa - Life cycle
The apical complex includes Vesicle (biology)|vesicles called rhoptries and micronemes, which open at the anterior of the cell
216
Apicomplexa - Life cycle
The presence of alveoli and other traits place the Apicomplexa among a group called the alveolates. Several related flagellates, such as Perkinsus marinus|Perkinsus and Colpodella, have structures similar to the polar ring and were formerly included here, but most appear to be closer relatives of the dinoflagellates. They are probably similar to the common ancestor of the two groups.
217
Apicomplexa - Life cycle
Another similarity is that many apicomplexan cells contain a single plastid, called the apicoplast, surrounded by either 3 or four membranes. Its functions are thought to include tasks such as lipid and heme biosynthesis, and it appears to be necessary for survival. In general, plastids are considered to have a common origin with the chloroplasts of dinoflagellates, and evidence points to an origin from red algae rather than green alga|green.
218
Apicomplexa - Life cycle
The Apicomplexa comprise the bulk of what used to be called the Sporozoa, a group for parasitic protozoans without flagella, pseudopods, or cilia. Most of the Apicomplexa are motile, however. The other main lines were the Ascetosporea, the Myxozoa (now known to be derived from animals), and the Microsporidia (now known to be derived from fungus|fungi). Sometimes the name Sporozoa is taken as a synonym for the Apicomplexa, or occasionally as a subset.
219
Apicomplexa - Blood-borne genera
Within the Apicomplexa there are three suborders of parasites.
220
Apicomplexa - Blood-borne genera
* suborder Adeleorina — 8 genera
221
Apicomplexa - Blood-borne genera
* suborder Haemosporina — all genera in this suborder
222
Apicomplexa - Blood-borne genera
* suborder Eimeriorina — 2 genera (Lankesterella and Schellackia)
223
Apicomplexa - Blood-borne genera
The Haemosporina includes the malaria parasites and their relatives.
224
Apicomplexa - Blood-borne genera
The Eimeriorina — the largest suborder in this phylum — the lifecycle involves both sexual and asexual stages. The asexual stages reproduce by schizogony. The male gametocyte produces a large number of gametes and the zygote gives rise to an oocyst, which is the infective stage. The majority are monoxenous (infect one host only) but a few are heteroxenous (lifecycle involves two or more hosts).
225
Apicomplexa - Blood-borne genera
Both the number of families in this later suborder is debated with the number of families being between one and twenty depending on the authority and the number of genera being between nineteen and twenty five. This somewhat unsatisfactory state of affairs awaits resolution with DNA based methods.
226
Apicomplexa - Disease genomics
One possible target for drugs is the plastid, and in fact existing drugs such as Tetracycline antibiotics|tetracyclines, which are effective against apicomplexans seem to operate against the plastid.
227
Apicomplexa - Disease genomics
Most apicomplexans have an apicoplast, (a non-photosynthetic plastid) and mitochondrion|mitochondrial and nuclear genomes, although Cryptosporidium species and gregarines are possible exceptions, as they are thought to have lost their plastids after the diverging last common ancestor of apicomplexans.
228
Apicomplexa - History The first Apicomplexan protozoan was seen by Antonie van Leeuwenhoek, who in 1674 saw oocysts of Eimeria stiedae in the gall bladder of a rabbit. The first member of the phylum to be named (by Dufour in 1828) was Gregarina ovata in earwigs. Since then, many more have been identified and named. During the quarter century 1826–1850, 41 species and 6 genera of Apicomplexa were named. In the quarter-century 1951–1975, 1873 new species and 83 new genera were added.
229
Apicomplexa - Taxonomy
The field of classifying Apicomplexa is in flux and classification has changed throughout the years since it was formally named in 1970.
230
Apicomplexa By 1987 a comprehensive survey of the phylum was completed: in all, 4516 species and 339 genera had been named. They consisted of:
231
Apicomplexa Although there has been considerable revision of this phylum (the order Haemosporidia now has 17 genera rather than 9), it seems likely these numbers are still approximately correct.
232
Apicomplexa - Jacques Euzéby (1988)
Jacques Euzéby in 1988 created a new class Haemosporidiasina by merging subclass Piroplasmasina and suborder Haemospororina.
233

*Subclass Haemosporidiasina
236
Apicomplexa - Jacques Euzéby (1988)
The division into Achromatorida and Chromatorida although proposed on morphological grounds may have a biological basis as the ability to store haemozoin appears to have evolved only once.
237
Apicomplexa - Roberts and Janovy (1996)
Roberts and Janovy in 1996 divided the phylum into the following subclasses and suborders (omitting classes and orders):
238
Apicomplexa - Roberts and Janovy (1996)
** Suborder Haemospororina (the haemospororins)
239
Apicomplexa - Roberts and Janovy (1996)
*Subclass Piroplasmasina (the piroplasms)
240
Apicomplexa - Roberts and Janovy (1996)
These form the following five taxonomic groups:
241
Apicomplexa - Roberts and Janovy (1996)
# The adeleorins are one-host parasites of invertebrates or vertebrates, or two-host parasites that alternately infect haematophagous (blood-feeding) invertebrates and the blood of vertebrates.
242
Apicomplexa - Roberts and Janovy (1996)
# The eimeriorins are a diverse group that includes one host species of invertebrates, two-host species of invertebrates, one-host species of vertebrates and two-host species of vertebrates. The eimeriorins are frequently called the coccidia. This term is often used to include the adeleorins.
243
Apicomplexa - Roberts and Janovy (1996)
# Haemospororins often known as the malaria parasites, are two-host Apicomplexa that parasitize blood-feeding dipteran flies and the blood of various tetrapod vertebrates.
244
Apicomplexa - Roberts and Janovy (1996)
# Piroplasms where all the species included are two-host parasites infecting ticks and vertebrates.
245
Apicomplexa - Perkins (2000)
This scheme is taken from Perkins et al. It is outdated as the Perkinsidae have since been recognised as a sister group to the dinoflagellates rather that the Apicomplexia. The remainder of the scheme appears to be valid:
246
Apicomplexa - Perkins (2000)
:::Macrogamete and microgamete develop separately. Syzygy does not occur. Ookinete has a conoid. Sporozoites have three walls. Heteroxenous: alternates between vertebrate host (in which merogony occurs) and invertebrate host (in which sporogony occurs). Usually blood parasites, transmitted by blood-sucking insects.

Voiceless dental sibilant - Comparison with the Spanish apico-alveolar sibilant
Astur-Leonese linguistic group|Astur-Leonese, Catalan language|Catalan, Basque language|Basque, Galician language|Galician, Portuguese language|Portuguese and Spanish language|Spanish) have a so-called voiceless apico-alveolar sibilant which lacks the strong hissing of the described in this article, but rather has a duller, more grave sound quality somewhat reminiscent of a voiceless retroflex sibilant

Voiceless dental sibilant - Comparison with the Spanish apico-alveolar sibilant
(for the more common sound), but Ladefoged and Maddieson claim that English can be pronounced apical, which is evidently not the same as the apical sibilant of Iberian Spanish and Basque, In addition, Adams asserts that many dialects of Modern Greek have a laminal sibilant with a sound quality similar to the apico-alveolar sibilant of northern Iberia.
252
Voiceless dental sibilant - Comparison with the Spanish apico-alveolar sibilant
Some authors have instead suggested that the difference lies in tongue shape. Adams describes the northern Iberian sibilant as retracted. Ladefoged and Maddieson appear to characterize the more common hissing variant as , and some phoneticians (e.g. J. Catford) have characterized it as sulcal (which is more or less a synonym of grooved), but in both cases there is some doubt about whether all and only the hissing sounds in fact have a grooved or sulcal tongue shape.

Intel VT - Interrupt virtualization (AMD AVIC, Intel APICv)
In 2012, AMD announced their Advanced Virtual Interrupt Controller (AVIC) targeting interrupt overhead reduction in virtualization environments.Wei Huang, [ Introduction of AMD Advanced Virtual Interrupt Controller], XenSummit 2012 This technology has yet to materialize in hardware and (as announced) does not support x2APIC.

Also in 2012, Intel announced a similar technology for interrupt and Advanced Programmable Interrupt Controller|APIC virtualization, which did not have a brand name at its announcement time. Later, it was branded as APIC virtualization (APICv) and it became commercially available in the Ivy Bridge (microarchitecture)|Ivy Bridge EP series of Intel CPUs, which is sold as Xeon E5-26xx v2 (launched in late 2013) and as Xeon E5-46xx v2 (launched in early 2014).

Marcus Gavius Apicius Gavius Apicius apparently owed his cognomen (his third name) to an earlier Apicius (1st century BC)|Apicius, who lived around 90 BC, whose family name it may have been: if this is true, Apicius had come to mean gourmand as a result of the fame of this earlier lover of luxury.
262
Marcus Gavius Apicius Evidence for the life of M. Gavius Apicius derives partly from contemporary or almost-contemporary sources but is partly filtered through the above-named work by Apion, whose purpose was presumably to explain the names and origins of luxury foods, especially those anecdotally linked to Apicius. From these sources the following anecdotes about M. Gavius Apicius (hereafter called 'Apicius') survive: to what extent they form a real biography is doubtful.
263
Marcus Gavius Apicius *Sejanus (20 BC – 18 October 31), afterwards well known as the minister and confidant of the emperor Tiberius, had in his youth sold his body to Apicius: Tacitus, Annals (Tacitus)|Annals [ 4.1].
264
Marcus Gavius Apicius *Apicius dined with Maecenas (70 – 8 BC), Augustus's adviser: Martial, Epigrams It is possible that Martial drew this idea from a facile comparison made by Seneca the Younger|Seneca between Maecenas, cultural adviser, and Apicius, gastronomic adviser.
265
Marcus Gavius Apicius *Julius Caesar Drusus|Drusus (13 BC - 14 September 23|AD 23), son of Tiberius, was persuaded by Apicius not to eat cymae, cabbage tops or cabbage sprouts, because they were a common food: Pliny the Elder, Natural History (Pliny)|Natural History [ ].
266
Marcus Gavius Apicius *The consuls of AD 28, Junius Blaesus and Lucius Antistius Vetus, dined luxuriously at Apicius' house: Claudius Aelianus|Aelian, Letters nos Domingo-Forasté .
267
Marcus Gavius Apicius *Tiberius saw a big red mullet in the market and wagered that Apicius or Publius Octavius would buy it. Both men began bidding for it and Octavius won: Seneca, Letters to Lucilius
268
Marcus Gavius Apicius *Apicius lived at Minturnae (Campania). Having heard of the boasted size and sweetness of the shrimps taken near the Libyan coast, Apicius commandeered a boat and crew, but when he arrived, disappointed by the shrimps he was offered by the local fishermen who came alongside in their boats, he turned round and returned to Minturnae without going ashore: Athenaeus, Deipnosophistae [ 1.7a].
269
Marcus Gavius Apicius *Apicius was born to enjoy every extravagant luxury that could be contrived. He advised that red mullet were at their best if, before cooking, they had been drowned in a bath of fish sauce made from red mullet: Pliny, Natural History [ 9:30].
270
Marcus Gavius Apicius *Apicius advised that flamingo's tongue was of superb flavour: Pliny, Natural History '[ 10:133]
271
Marcus Gavius Apicius *Based on existing methods of producing goose liver (foie gras), Apicius devised a similar method of producing pork liver. He fed his pigs with dried ficus|figs and slaughtered them with an overdose of Ancient Roman cuisine#Alcoholic drinks|mulsum (honeyed wine): Pliny, Natural History
272
Marcus Gavius Apicius *Having spent a fortune of 100 million sestertii on his kitchen, spent all the gifts he had received from the Imperial court, and thus swallowed up his income in lavish hospitality, Apicius found that he had only 10 million sestertii left. Afraid of dying in relative poverty, he poisoned himself: Seneca, Consolatio ad Helviam 10.
273
Marcus Gavius Apicius Several recipes were named after Apicius, and probably M. Gavius Apicius is the person intended:
274
Marcus Gavius Apicius *A method of cooking cabbage, marinading in oil and salt and using soda to retain greenness: Pliny, Natural History
275
Marcus Gavius Apicius *A kind of cake: Chrysippus of Tyana quoted by Athenaeus, Deipnosophistae 647c.
276
*Seven recipes in the Apicius cookbook .
Marcus Gavius Apicius *Seven recipes in the Apicius cookbook .
277
Marcus Gavius Apicius The first such reference may be that in the Scholia on Juvenal (4.22), which assert that Apicius wrote about how to arrange dinners, and about sauces.

Apiculture 'Beekeeping' (or 'apiculture', from bee) is the maintenance of honey bee colonies, commonly in beehive|hives, by humans. A beekeeper (or apiarist) keeps bees in order to collect their honey and other products that the hive produces (including beeswax, propolis, pollen, and royal jelly), to pollination|pollinate crops, or to produce bees for sale to other beekeepers. A location where bees are kept is called an apiary or bee yard.

Early forms of honey collecting entailed the destruction of the entire colony when the honey was harvested
343
Apiculture - Invention of the movable comb hive
During the medieval period abbeys and monastery|monasteries were centers of beekeeping, since beeswax was highly prized for candles and fermented honey was used to make alcoholic mead in areas of Europe where vines would not grow. The 18th and 19th centuries saw successive stages of a revolution in beekeeping, which allowed the bees themselves to be preserved when taking the harvest.
344
Apiculture - Invention of the movable comb hive
Intermediate stages in the transition from the old beekeeping to the new were recorded for example by Thomas Wildman in 1768/1770, who described advances over the destructive old skep-based beekeeping so that the bees no longer had to be killed to harvest the honey.Thomas Wildman, A Treatise on the Management of Bees (London, 1768, 2nd edn 1770)

However, the forerunners of the modern hives with movable frames that are mainly used today are considered the traditional basket top bar (movable comb) hives of Greece, known as “Greek beehives”
346
Apiculture - Invention of the movable comb hive
The 19th century saw this revolution in beekeeping practice completed through the perfection of the movable comb hive by the American Lorenzo Langstroth|Lorenzo Lorraine Langstroth
347
Apiculture - Invention of the movable comb hive
The invention and development of the movable-comb-hive fostered the growth of commercial honey production on a large scale in both Europe and the USA (see also Beekeeping in the United States).
348
Apiculture - Evolution of hive designs
Langstroth's design for movable comb hives was seized upon by apiarists and inventors on both sides of the Atlantic Ocean|Atlantic and a wide range of moveable comb hives were designed and perfected in England, France, Germany and the United States
349
Apiculture - Evolution of hive designs
The differences in hive dimensions are insignificant in comparison to the common factors in all these hives: they are all square or rectangular; they all use movable wooden frames; they all consist of a floor, brood-box, honey super, crown-board and roof. Hives have traditionally been constructed of Cedrus|cedar, pine, or cypress wood, but in recent years hives made from injection molded dense polystyrene have become increasingly important.
350
Apiculture - Evolution of hive designs
Hives also use queen excluders between the brood-box and honey supers to keep the queen from laying eggs in cells next to those containing honey intended for consumption. Also, with the advent in the 20th century of mite pests, hive floors are often replaced for part of (or the whole) year with a wire mesh and removable tray.
351
Apiculture - Pioneers of practical and commercial beekeeping
The 19th century produced an explosion of innovators and inventors who perfected the design and production of beehives, systems of management and husbandry, stock improvement by selective breeding, honey extraction and marketing. Preeminent among these innovators were:

Apiculture - Fixed comb hives
A fixed comb hive is a hive in which the combs cannot be removed or manipulated for management or harvesting without permanently damaging the comb. Almost any hollow structure can be used for this purpose, such as a log gum, skep or a clay pot. Fixed comb hives are no longer in common use in industrialized countries, and are illegal in some places that require inspection for problems such as varroa and American foulbrood.
365
Apiculture - Fixed comb hives
In many developing countries fixed comb hives are widely used and, because they can be made from any locally available material, are very inexpensive. Beekeeping using fixed comb hives is an essential part of the livelihoods of many communities in poor countries. The charity Bees for Development recognizes that local skills to manage bees in fixed comb hives are widespread in Africa, Asia, and South America.
366
Apiculture - Movable frame hives
In the United States, the Langstroth hive is commonly used
367
Apiculture - Top-bar hives
A growing number of amateur beekeepers are adopting various top-bar hives similar to the type commonly found in Africa
368
Apiculture - Top-bar hives
Some of the most well known top-bar hives are the Kenyan Top Bar Hive with sloping sides, the Tanzanian Top Bar Hive with straight sides, and Vertical Top Bar Hives, such as the Warre or People's Hive designed by Abbe Warre in the mid-1900s.
369
Apiculture - Top-bar hives
The initial costs and equipment requirements are far less. Scrap wood or #2 or #3 pine can often be used build a nice hive. Top-bar hives also offer some advantages to interacting with the bees and the amount of weight that must be lifted is greatly reduced. Top-bar hives are being widely used in developing countries in Africa and Asia as a result of the Bees for Development program. Since 2011, a growing number of beekeepers in the U.S. are using various top-bar hives.
370
Apiculture - Protective clothing
While knowledge of the bees is the first line of defense, most beekeepers also wear some protective clothing. Novice beekeepers usually wear gloves and a hooded suit or hat and veil. Experienced beekeepers sometimes elect not to use gloves because they inhibit delicate manipulations. The face and neck are the most important areas to protect, so most beekeepers wear at least a veil.
371
Apiculture - Protective clothing
Defensive bees are attracted to the breath, and a sting on the face can lead to much more pain and swelling than a sting elsewhere, while a sting on a bare hand can usually be quickly removed by fingernail scrape to reduce the amount of venom injected.
372
Apiculture - Protective clothing
The protective clothing is generally light colored (but not colorful) and of a smooth material. This provides the maximum differentiation from the colony's natural predators.
373
Apiculture - Protective clothing
'Stings' retained in clothing fabric continue to pump out an Alarm pheromones|alarm pheromone that attracts aggressive action and further stinging attacks. Washing suits regularly, and rinsing gloved hands in vinegar minimizes attraction.
374
Smoke is the beekeeper's third line of defense
Apiculture - Smoker Smoke is the beekeeper's third line of defense
375
Apiculture - Smoker Smoke is of questionable use with a swarm, because swarms do not have honey stores to feed on in response. Usually smoke is not needed, since swarms tend to be less defensive, as they have no stores to defend, and a fresh swarm has fed well from the hive.
376
Apiculture - Smoker Many types of fuel can be used in a smoker as long as it is natural and not contaminated with harmful substances
377
Apiculture - Smoker Some beekeepers are using liquid smoke as a safer, more convenient alternative. It is a water-based solution that is sprayed onto the bees from a plastic spray bottle.
378
Apiculture - Smoker Torpor may also be induced by the introduction of chilled air into the hive - while chilled carbon dioxide may have harmful long-term effects.
379
Apiculture - Effects of stings and of protective measures
Some beekeepers believe that the more stings a beekeeper receives, the less irritation each causes, and they consider it important for safety of the beekeeper to be stung a few times a season
380
Apiculture - Effects of stings and of protective measures
The entry of venom into the body from bee-stings may also be hindered and reduced by protective clothing that allows the wearer to remove stings and venom sacs with a simple tug on the clothing. Although the stinger is barbed, a worker bee is less likely to become lodged into clothing than human skin.
381
Apiculture - Natural beekeeping
The natural beekeeping movement believes that modern beekeeping and agricultural practices, such as crop spraying, hive movement, frequent hive inspections, artificial insemination of queens, routine medication, and sugar water feeding, weaken bee hives.
382
Apiculture - Natural beekeeping
Practitioners of 'natural beekeeping' tend to use variations of the top-bar hive, which is a simple design that retains the concept of movable comb without the use of frames or foundation
383
Apiculture - Natural beekeeping
The most popular vertical top-bar hive is probably the Warré hive, based on a design by the French priest Abbé Émile Warré (1867–1951) and popularized by Dr. David Heaf in his English translation of Warré's book L'Apiculture pour Tous as Beekeeping For All.
384
Apiculture - Urban or backyard beekeeping
Urban apiculture has undergone a renaissance in the first decade of the 21st century, and urban beekeeping is seen by many as a growing trend; it has recently been legalized in cities where it was previously banned
385
Apiculture - Urban or backyard beekeeping
Some have found that city bees are actually healthier than rural bees because there are fewer pesticides and greater biodiversity. Urban bees may fail to find forage, however, and homeowners can use their landscapes to help feed local bee populations by planting flowers that provide nectar and pollen. An environment of year-round, uninterrupted bloom creates an ideal environment for colony reproduction.

Apiculture - Castes *a queen bee, which is normally the only breeding female in the colony;
387
Apiculture - Castes *a large number of female worker bees, typically 30,000–50,000 in number;
388
Apiculture - Castes *a number of male Drone (bee)|drones, ranging from thousands in a strong hive in spring to very few during dearth or cold season.
389
Apiculture - Castes The queen is the only sexually mature female in the hive and all of the female worker bees and male drones are her offspring
390
Apiculture - Mating of queens
The queen emerges from her cell after 15 days of development and she remains in the hive for 3–7 days before venturing out on a mating flight
391
Apiculture - Mating of queens
Mating takes place at some distance from the hive and often several hundred feet in the air; it is thought that this separates the strongest drones from the weaker ones, ensuring that only the fastest and strongest drones get to pass on their genes.
392
Apiculture - Worker bees
Almost all the bees in a hive are female worker bees. At the height of summer when activity in the hive is frantic and work goes on non-stop, the life of a worker bee may be as short as 6 weeks; in late autumn, when no brood is being raised and no nectar is being harvested, a young bee may live for 16 weeks, right through the winter. During its life a worker bee performs different work functions in the hive, largely dictated by the age of the bee.
393
Apiculture - Structure of a bee colony
A domesticated bee colony is normally housed in a rectangular hive body, within which eight to ten parallel frames house the vertical plates of honeycomb that contain the eggs, larvae, pupae and food for the colony. If one were to cut a vertical cross-section through the hive from side to side, the brood nest would appear as a roughly ovoid ball spanning 5-8 frames of comb. The two outside combs at each side of the hive tend to be exclusively used for long-term storage of honey and pollen.
394
Apiculture - Structure of a bee colony
Within the central brood nest, a single frame of comb typically has a central disk of eggs, larvae and sealed brood cells that may extend almost to the edges of the frame
395
Apiculture - Structure of a bee colony
Apart from the honey stored within the central brood frames, the bees store surplus honey in combs above the brood nest
396
Apiculture - Annual cycle of a bee colony
The development of a bee colony follows an annual cycle of growth that begins in spring with a rapid expansion of the brood nest, as soon as pollen is available for feeding larvae
397
Apiculture - Annual cycle of a bee colony
The key factor in this is the prevention or skillful management of the swarming impulse
398
Apiculture - Colony reproduction: swarming and supersedure
All colonies are totally dependent on their queen, who is the only egg-layer
399
Apiculture - Colony reproduction: swarming and supersedure
All the time that the queen is fertile and laying eggs she produces a variety of pheromones, which control the behavior of the bees in the hive
400
Apiculture - Colony reproduction: swarming and supersedure
At this juncture, the bees produce one or more queen cells by modifying existing worker cells that contain a normal female egg. However, the bees pursue two distinct behaviors:
401
Apiculture - Colony reproduction: swarming and supersedure
# Supersedure: queen replacement within one hive without swarming
402
Apiculture - Colony reproduction: swarming and supersedure
# Swarm cell production: the division of the hive into two colonies by swarming
403
Apiculture - Colony reproduction: swarming and supersedure
Different sub-species of Apis mellifera exhibit differing swarming characteristics that reflect their evolution in different ecotopes of the European continent. In general the more northerly black races are said to swarm less and supersede more, whereas the more southerly yellow and grey varieties are said to swarm more frequently. The truth is complicated because of the prevalence of cross-breeding and hybridization of the sub species and opinions differ.
404
Apiculture - Colony reproduction: swarming and supersedure
Supersedure is highly valued as a behavioral trait by beekeepers because a hive that supersedes its old queen does not swarm and so no stock is lost; it merely creates a new queen and allows the old one to fade away, or alternatively she is killed when the new queen emerges. When superseding a queen, the bees produce just one or two queen cells, characteristically in the center of the face of a broodcomb.
405
Apiculture - Colony reproduction: swarming and supersedure
In swarming, by contrast, a great many queen cells are created—typically a dozen or more—and these are located around the edges of a broodcomb, most often at the sides and the bottom.
406
Apiculture - Colony reproduction: swarming and supersedure
Once either process has begun, the old queen normally leaves the hive with the hatching of the first queen cells
407
Apiculture - Factors that trigger swarming
It is generally accepted that a colony of bees does not swarm until they have completed all of their brood combs, i.e., filled all available space with eggs, larvae, and brood
408
Apiculture - Factors that trigger swarming
Another important factor in swarming is the age of the queen. Those under a year in age are unlikely to swarm unless they are extremely crowded, while older queens have swarming predisposition.
409
Apiculture - Factors that trigger swarming
Beekeepers monitor their colonies carefully in spring and watch for the appearance of queen cells, which are a dramatic signal that the colony is determined to swarm.
410
Apiculture - Factors that trigger swarming
When a colony has decided to swarm, queen cells are produced in numbers varying to a dozen or more
411
Apiculture - Factors that trigger swarming
This swarm looks for shelter. A beekeeper may capture it and introduce it into a new hive, helping meet this need. Otherwise, it returns to a feral state, in which case it finds shelter in a hollow tree, excavation, abandoned chimney, or even behind shutters.
412
Apiculture - Factors that trigger swarming
Back at the original hive, the first virgin queen to emerge from her cell immediately seeks to kill all her rival queens still waiting to emerge. Usually, however, the bees deliberately prevent her from doing this, in which case, she too leads a second swarm from the hive. Successive swarms are called 'after-swarms' or 'casts' and can be very small, often with just a thousand or so bees—as opposed to a prime swarm, which may contain as many as ten to twenty-thousand bees.
413
Apiculture - Factors that trigger swarming
A small after-swarm has less chance of survival and may threaten the original hive's survival if the number of individuals left is unsustainable. When a hive swarms despite the beekeeper's preventative efforts, a good management practice is to give the reduced hive a couple frames of open brood with eggs. This helps replenish the hive more quickly and gives a second opportunity to raise a queen if there is a mating failure.
414
Apiculture - Factors that trigger swarming
Each race or sub-species of honey bee has its own swarming characteristics. Italian bees are very prolific and inclined to swarm; Northern European black bees have a strong tendency to supersede their old queen without swarming. These differences are the result of differing evolutionary pressures in the regions where each sub-species evolved.
415
Apiculture - Artificial swarming
When a colony accidentally loses its queen, it is said to be queenless
416
Apiculture - Artificial swarming
Beekeepers use the ability of the bees to produce new queens to increase their colonies in a procedure called splitting a colony
417
Apiculture - Diseases The common agents of disease that affect adult honey bees include Fungus|fungi, bacteria, protozoa, viruses, parasitism|parasites, and poisons
418
Apicoplast An 'apicoplast' is a derived non-photosynthetic plastid found in most Apicomplexa, including malaria parasites such as Plasmodium falciparum, but not in others such as Cryptosporidium. It originated from an alga (there is debate as to whether this was a green or red alga) through secondary endosymbiosis. The apicoplast is surrounded by four membranes within the outermost part of the endomembrane system.
419
Apicoplast - Significance
Furthermore, herbicides may be able to specifically target the parasite's plant-like apicoplast and without any noticeable effect on the mammalian host's cells.
420
Apicoplast - Evolutionary origin
Evidence suggests that the apicoplast is a product of secondary endosymbiosis, and that the apicoplast may be homologous to the secondary plastid of the closely related dinoflagellate algae. An ancient cyanobacterium was first engulfed by a eukaryotic cell but was not digested. The bacterium escaped being digested because it formed a symbiotic relationship with the host eukaryotic cell; both the eukaryote and the bacterium mutually benefited from their novel shared existence.
421
Apicoplast - Evolutionary origin
During the reorganization of the plastid the apicoplast lost its ability to photosynthesize
422
Apicoplast - Architecture and distribution
Within the apicoplast's membrane is a 35 kb long circular DNA strand that codes for approximately 30 proteins, tRNAs and some RNAs
423
Apicoplast - Function The functions of apicoplasts have not been conclusively defined. However, it has been established that the apicoplast is a vital organelle to the parasite's survival.
424
Apicoplast - Fatty Acid Synthesis
The destruction of the apicoplast does not immediately kill the parasite but instead prevents it from invading new host cells. This observation suggests that the apicoplast may be involved in lipid metabolism. If unable to synthesize sufficient fatty acids the parasite is unable to form the parasitophorous vacuole (PV) that is imperative to a successful invasion of host cells. This conclusion is supported by the discovery of Type II Fatty Acid Synthase (FAS) machinery in the apicoplast.
425
Apicoplast - Isoprenoid Synthesis
The apicoplast is also thought to have a role in isoprenoid synthesis, which are prosthetic groups on many enzymes and also act as precursors to ubiquinones (involved in electron transport) and dolichols (involved in glycoprotein formation). The apicoplast contains the DOXP pathway for isoprenoid synthesis and is the sole site for synthesis in the Plasmodium genome.
426
Apicoplast - Heme synthesis
The apicoplast has also been implicated with heme synthesis and amino acid synthesis. It is also suggested to have a role in cell development. These functions, however, are merely postulations and are not yet conclusively supported by experimentation.
427
Apicoplast - Iron-sulphur cluster synthesis
Various iron-sulphur cluster biosynthetic enzymes including SufB or Orf470 have been identified in the apicoplast genome.
428
Periapical abscess In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, Pulp (tooth)|pulp of the tooth
429
Periapical abscess A dental abscess is a type of odontogenic infection, although commonly the latter term is applied to an infection which has spread outside the local region around the causative tooth.
430
Periapical abscess - Classification
* Periapical abscess: The result of a chronic (medicine)|chronic, localized infection located at the tip, or Dental anatomy#Surfaces|apex, of the root of a tooth.
431
Periapical abscess - Classification
* Gingival abscess: involving only the gum tissue, without affecting either the tooth or the periodontal ligament (see: periodontal abscess)
432
Periapical abscess - Classification
* Pericoronal abscess: involving the soft tissues surrounding the crown of a tooth (see: Pericoronitis)
433
Periapical abscess - Classification
* Combined periodontic-endodontic abscess: a situation in which a periapical abscess and a periodontal abscess have combined (see: Combined periodontic-endodontic lesions).
434
Periapical abscess - Signs and symptoms
The pain is continuous and may be described as extreme, growing, sharp, shooting, or throbbing. Putting pressure or warmth on the tooth may induce extreme pain. The area may be sensitive to touch and possibly swollen as well. This swelling may be present at either the base of the tooth, the gum, and/or the cheek, and sometimes can be reduced by applying ice packs.
435
Periapical abscess - Signs and symptoms
An acute abscess may be painless but still have a swelling present on the gum. It is important to get anything that presents like this checked by a dental professional as it may become chronic later.
436
Periapical abscess - Signs and symptoms
In some cases, a tooth abscess may perforate bone and start draining into the surrounding tissues creating local facial swelling. In some cases, the lymph glands in the neck will become swollen and tender in response to the infection. It may even feel like a migraine as the pain can transfer from the infected area. The pain does not normally transfer across the face, only upwards or downwards as the nerves that serve each side of the face are separate.
437
Periapical abscess - Signs and symptoms
Severe aching and discomfort on the side of the face where the tooth is infected is also fairly common, with the tooth itself becoming unbearable to touch due to extreme amounts of pain.
438
Periapical abscess - Diagnostic approach
In order to diagnose a dental abscess thorough medical and dental histories must be taken, extraoral and intraoral examinations performed and radiographic images obtained. A periodontal abscess may be difficult to distinguish from a periapical abscess. Indeed sometimes they can occur together. Since the management of a periodontal abscess is different from a periapical abscess, this differentiation is important to make. The following factors may help to this:
439
Periapical abscess - Diagnostic approach
* Similarly, in a periodontal abscess pus most likely discharges via the periodontal pocket, whereas a periapical abscess generally drains via a parulis nearer to the apex of the involved tooth.
440
Periapical abscess - Diagnostic approach
* In periodontal abscesses, the swelling usually precedes the pain, and in periapical abscesses, the pain usually precedes the swelling.
441
Periapical abscess - Diagnostic approach
* A history of toothache with sensitivity to hot and cold suggests previous pulpitis, and indicates that a periapical abscess is more likely.
442
Periapical abscess - Diagnostic approach
* If the tooth which gives normal results on pulp sensibility testing, is free of dental caries and has no large restorations; it is more likely to be a periodontal abscess.
443
Periapical abscess - Diagnostic approach
* A dental radiograph is of little help in the early stages of an dental abscess, but later usually the position of the abscess, and hence indication of endodontal/periodontal etiology determined. If there is a sinus, a gutta percha point is sometimes inserted before the x-ray in the hope that it will point to the origin of the infection.
444
Periapical abscess - Diagnostic approach
* Generally, periodontal abscesses will be more tender to lateral percussion than to vertical, and periapical abscesses will be more tender to apical percussion.
445
Periapical abscess - Diagnostic approach
A way to differentiate periapical abscesses from cemento-osseous dysplasia is to use percussion and/or a vitality test to determine the presence of an abscess
446
Periapical abscess - Diagnostic approach
• Non-Hodgkin Lymphoma can occur in the oral cavity and can present clinically as a dental abscess. If patients fail to respond to conventional therapies, such as endodontic procedures, then the clinician needs to be on alert for a differential diagnosis. Not taking a biopsy could result in a delay in treatment of a neoplastic condition. This in turn could influence the overall prognosis and outcome.(9)
447
Periapical abscess - Diagnostic approach
• Plasmacytomas exhibit bucco-palatal swelling, expansion, well-defined margins and a smooth surface; the swelling can cause nasal obstruction and epistaxis
448
Periapical abscess - Treatment
Successful treatment of a dental abscess centers on the reduction and elimination of the offending organisms.
449
Periapical abscess - Treatment
This can include treatment with antibioticshttp:// and drainage. If the tooth can be restored, root canal therapy can be performed. Non-restorable teeth must be tooth extraction|extracted, followed by curettage of all apical soft tissue.
450
Periapical abscess - Treatment
Unless they are symptomatic, teeth treated with root canal therapy should be evaluated at 1- and 2-year intervals after the root canal therapy to rule out possible lesional enlargement and to ensure appropriate healing.
451
Periapical abscess - Treatment
* Inadequate root canal therapy
452
Periapical abscess - Treatment
* Vertical root fractures
453
Periapical abscess - Treatment
* Penetration of the maxillary sinus
454
Periapical abscess - Treatment
Following conventional, adequate root canal therapy, abscesses that do not heal or enlarge are often treated with surgery and filling the root tips; and will require a biopsy to evaluate the diagnosis.
455
Periapical abscess - Untreated consequences
If left untreated, a severe tooth abscess may become large enough to perforate bone and extend into the soft tissue eventually becoming osteomyelitis and cellulitis respectively. From there it follows the path of least resistance and may spread either internally or externally. The path of the infection is influenced by such things as the location of the infected tooth and the thickness of the bone, muscle and fascia attachments.
456
Periapical abscess - Untreated consequences
External drainage may begin as a boil which bursts allowing pus drainage from the abscess, intraorally (usually through the gum) or extraorally. Chronic drainage will allow an epithelial lining to form in this communication to form a pus draining canal (fistula). Sometimes this type of drainage will immediately relieve some of the painful symptoms associated with the pressure.
457
Periapical abscess - Untreated consequences
Internal drainage is of more concern as growing infection makes space within the tissues surrounding the infection
458
Periapical abscess - Untreated consequences
Depending on the severity of the infection, the sufferer may feel only mildly ill, or may in extreme cases require hospital care.

Apical meristem A 'meristem' is the biological tissue|tissue in most plants containing undifferentiated cells ('meristematic cells'), found in zones of the plant where growth can take place.
461
Apical meristem The shoot apical meristem (SAM) gives rise to organs like the leaves and flowers, while the root apical meristem (RAM) provides the meristematic cells for the future root growth
462
Apical meristem The term meristem was first used in 1858 by Karl Wilhelm von Nägeli (1817–1891) in his book Beiträge zur Wissenschaftlichen Botanik.Galun, Esra (2007)
463
Apical meristem In general, differentiated plant cells cannot divide or produce cells of a different type. Therefore, mitosis|cell division in the meristem is required to provide new cells for expansion and differentiation of tissues and initiation of new organs, providing the basic structure of the plant body.
464
Apical meristem Meristematic cells are incompletely or not at all cellular differentiation|differentiated, and are capable of continued cellular division (youthful)
465
Apical meristem Maintenance of the cells requires a balance between two antagonistic processes: organ initiation and stem cell population renewal.
466
Apical meristem Apical meristems are the completely undifferentiated (indeterminate) meristems in a plant. These differentiate into three kinds of primary meristems. The primary meristems in turn produce the two secondary meristem types. These secondary meristems are also known as lateral meristems because they are involved in lateral growth.
467
Apical meristem At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone. Cells of this zone have a stem cell function and are essential for meristem maintenance. The proliferation and growth rates at the meristem summit usually differ considerably from those at the periphery.
468
Apical meristem Meristems also are induced in the roots of legumes such as soybean, Lotus japonicus, pea, and Medicago truncatula after infection with soil bacteria commonly called Rhizobium
469
Apical meristem - Root apical meristem
NATURE REVIEWS MOLECULAR CELL BIOLOGY.15(5): doi: /nrm3790 Root apical meristem and tissue patterns become established in the embryo in the case of the primary root, and in the new lateral primordium in the case of secondary roots.
470
Apical meristem - Intercalary meristem
In angiosperms, intercalary meristems occur only in monocot (in particular, grass) stems at the base of nodes and leaf blades
471
Apical meristem - Floral meristem
When plants begin the developmental process known as flowering, the shoot apical meristem is transformed into an inflorescence meristem, which goes on to produce the floral meristem, which produces the familiar sepals, petals, stamens, and carpels of the flower.
472
Apical meristem - Floral meristem
In contrast to vegetative apical meristems and some exflorescence meristems, floral meristems are responsible for determinate growth, the limited growth of the flower to a particular size and form
473
Apical meristem - Floral meristem
Through the years, scientists have manipulated floral meristems for economics reasons. An example is the mutant tobacco plant Maryland Mammoth. In 1936, the department of agriculture of Switzerland performed several scientific tests with this plant. Maryland Mammoth is peculiar in this sense that it grows much faster than other tobacco plants.
474
Apical meristem - Diversity in meristem architectures
Is the mechanism of being indeterminate conserved in the SAMs of the plant world? The SAM contains a population of stem cells that also produce the lateral meristems while the stem elongates
475
Apical meristem - Role of the KNOX-family genes
Genetic screens have identified genes belonging to the KNOX (genes)|KNOX family in this function
476
Apical meristem - Role of the KNOX-family genes
The KNOX family has also been implicated in leaf shape evolution (See below for a more detailed discussion)
477
Apical meristem - Primary meristems
* 'Protoderm': lies around the outside of the stem and develops into the Epidermis (botany)|epidermis.
478
Apical meristem - Primary meristems
* 'Procambium': lies just inside of the protoderm and develops into primary xylem and primary phloem
479
Apical meristem - Primary meristems
* 'Ground meristem': develops into the Cortex (botany)|cortex and the pith. Composed of parenchyma, collenchyma and sclerenchyma cells.
480
Apical meristem - Secondary meristems
There are two types of secondary meristems, these are also called the lateral meristems because they surround the established stem of a plant and cause it to grow laterally (i.e., larger in diameter).
481
Apical meristem - Secondary meristems
* Vascular cambium, which produces secondary xylem and secondary phloem. This is a process that may continue throughout the life of the plant. This is what gives rise to wood in plants. Such plants are called arborescent. This does not occur in plants that do not go through secondary growth (known as herbaceous plants).
482
Apical meristem - Secondary meristems
* Cork cambium, which gives rise to the periderm, which replaces the epidermis.
483
Apical meristem - Indeterminate growth of meristems
Primary growth gives rise to the apical part of many plants.
484
Apical meristem - Indeterminate growth of meristems
The growth of nitrogen fixing nodules on legume plants such as soybean and pea is either determinate or indeterminate
485
Apical meristem - Cloning
Under appropriate conditions, each shoot meristem can develop into a complete new plant or cloning|clone. Such new plants can be grown from shoot cuttings that contain an apical meristem. Root apical meristems are not readily cloned, however. This cloning is called 'asexual reproduction' or 'vegetative reproduction' and is widely practiced in horticulture to mass-produce plants of a desirable genotype. This process is also known as mericloning.
486
Apical meristem - Cloning
Propagating through cuttings is another form of vegetative propagation that initiates root or shoot production from secondary meristematic cambial cells. This explains why basal 'wounding' of shoot-borne cuttings often aids root formation.

Postalveolar - Point of tongue contact (laminal, apical, subapical)
Apical and subapical articulations are always tongue-up, with the tip of the tongue above the teeth, while laminal articulations are often tongue-down, with the tip of the tongue behind the lower teeth.

495
Periapical cyst The 'periapical cyst' (also termed 'radicular cyst', and to a lesser extent 'dental cyst') is the most common odontogenic odontogenic cyst|cyst. It is caused by Pulp (tooth)|pulpal necrosis secondary to dental caries or dental trauma|trauma. The cyst lining is derived from the cell rests of Malassez. Usually, the periapical cyst is asymptomatic, but a secondary infection can cause toothache|pain. On radiographs, it appears a radiolucency (dark area) around the apex of a tooth's root.
496
Periapical cyst Radicular cyst is the most common odontogenic cystic lesion of inflammatory origin. It is also known as periapical cyst, apical periodontal cyst, root end cyst or dental cyst. It arises from epithelial residues in periodontal ligament as a result of inflammation. The inflammation usually follows death of dental pulp. Radicular cysts are found at root apices of involved teeth. These cysts may persists even after extraction of offending tooth; such cysts are called residual cysts.
497
Periapical cyst - Definition
It is defined as an odontogenic cyst of Inflammatory origin that is preceded by a chronic periapical granuloma and stimulation of cell rests of malassez present in the periodontal membrane.
498
Periapical cyst - Classification
1) Periapical Cyst: These are the radicular cysts which are present at root apex.
499
Periapical cyst - Classification
2) Lateral Radicular Cyst:- These are the radicular cysts which are present at the opening of lateral accessory root canals of offending tooth.
500
Periapical cyst - Classification
3) Residual Cyst:- These are the radicular cysts which remains even after extraction of offending tooth.
501
Periapical cyst - Causes
This inflammation leads to the formation of reactive inflammatory (scar) tissue called periapical granuloma further necrosis and damage stimulates the Malassez epithelial rests, which are found in the periodontal ligament, resulting in the formation of a cyst that may be infected or sterile (The epithelium undergoes necrosis and the granuloma becomes a cyst)
502
Periapical cyst - Etiology
A Radicular Cyst presupposes physical, chemical or bacterial injury resulting in death of pulp followed by stimulation of epithelial cell rests of malaseez which are present normally in periodontal ligament.
503
Periapical cyst - Pathogenesis
Pathogenesis of Radicular Cyst is conveniently considered in 3 Phases, which are as follows
504
Periapical cyst - Phase of Initiation
* Respiratory epithelium of Maxillary sinus when periapical lesion communicates with sinus wall.
505
Periapical cyst - Phase of Initiation
* Oral epithelium from fistulous tract.
506
Periapical cyst - Phase of Initiation
* Oral epithelium proliferating apically from periodontal pocket.
507
Periapical cyst - Phase of Initiation
The mechanism of stimulation of epithelial cells to proliferate is not clear. It may be due to inflammation in periapical granuloma or some products of dead pulp may initiate the process and at same time it evokes an inflammatory reaction. There is also evidence of local changes in supporting connective tissue which may be responsible for activating the cell rests of malaseez.
508
Periapical cyst - Phase of Cyst Formation
It is a process by which cavity becomes lined by proliferating epithelium.
509
Periapical cyst - Phase of Cyst Formation
* Most widely accepted theory suggests that initial reaction leading to cyst formation is a proliferation of epithelial rests in periapical area involved by granuloma
510
Periapical cyst - Phase of Cyst Formation
* The another theory suggest that a cyst may form through proliferation of epithelium to line a pre-existing cavity formed through focal necrosis and degeneration of connective tissue in periapical granuloma. But the finding of epithelium or epithelial proliferation near an area of necrosis is not common.
511
Periapical cyst - Phase of Cyst Enlargement
Experimental work provided evidence that osmosis makes contribution to increase in size of cyst. Investigators found that fluids of Radicular cysts have Gamma Globulin level High by almost more than half to patient’s own serum. Plasma protein exudate Hyaluronic acid as well as products of cell breakdown contribute to high osmotic pressure of cystic fluid on cyst walls which causes resorption of bone and enlargement of cyst.
512
Periapical cyst - Microbiology
Cyst may or may not be infected. Whenever an infection is present, Actinomyces organisms have been isolated from radicular cyst.
513
Periapical cyst - Microbiology
Microorganisms mainly found in root canal are 75% Gram +ve 24% Gram –ve, among which Streptococci are predominant’ also other Gram +ve organisms like Staphylococci, Cornybacterium, yeast and others are found. Gram -ve organisms are Spirochetes, Nesseria, Bacteroids, fusobacterium, pseudomonas and others.

As soon as it enters the maxillary antrum the expansion starts to occur a little faster because there is space available for expansion. Tapping the affected teeth will cause shooting pain. This is virtually diagnostic of pulpal infection.

Periapical cyst - Clinical features
A) Frequency:- It is most common cystic lesion of jaw comprising approximately 52.3% of jaw cystic lesions
521
Periapical cyst - Clinical features
B) Age:- Large no. of cases are found in 4th 5th decades of life after which there is gradual decline.
522
Periapical cyst - Clinical features
C) Sex:- It is more common in males comprising about 58% in females comprising about 42%.
523
Periapical cyst - Clinical features
D) Race:-White patients are involved with a frequency of about twice that of Black patients.
524
Periapical cyst - Clinical features
E) Site:- It occurs with frequency of 60% in Maxilla. Though it may occur in all tooth bearing areas of both the jaws but preferably it occurs in maxillary anterior region. Upper lateral Incisors and dens in dente are usually the offending teeth. It occurs most commonly at apices of involved teeth. They may however be found at lateral accessory root canals.
525
Periapical cyst - Gross Features
Gross Specimen may be spheroidal or ovoid intact cystic masses, but often they are irregular and collapsed. The walls vary from extremely thin to a thickness of about 5mm. The inner surface may be smooth or corrugated yellow mural nodules of cholesterol may project into the cavity. The fluid contents are usually brown from breakdown of blood and when cholesterol crystals are present they impart an orange gold or straw colour.
526
Periapical cyst - Clinical Presentation
Smaller radicular cysts are usually symptomless and may be discovered when intraoral periapical (IOPA) radiographs are taken of non-vital teeth.
527
Periapical cyst - Clinical Presentation
Larger lesions show slowly enlarging swelling. At first the enlargement is bony hard but as cyst increases in size, the covering bone becomes very thin, despite subperiosteal deposition and swelling exhibits springiness, only when cyst has become completely eroded, the bone will show fluctuation.
528
Periapical cyst - Clinical Presentation
In Maxilla, there may be buccal and palatal enlargement Whereas in mandible it is usually labial or buccal and only rarely lingual.
529
Periapical cyst - Clinical Presentation
Pain infection are other clinical features of some radicular cysts. These cysts are painless unless infected. However, complain of pain is also observed in patient without any evidence of infection.
530
Periapical cyst - Clinical Presentation
Occasionally, a sinus may lead from cyst cavity to the oral mucosa
531
Periapical cyst - Clinical Presentation
Quite often there may be more than one radicular cyst. Scientists believe that there are cyst prone individuals who show particular susceptibility to develop radicular cysts.
532
Periapical cyst - Clinical Presentation
Radicular cysts arising from deciduous tooth are very rare.Deciduous tooth which had been treated endodontically with materials containing Formecresol which in combination with tissue protein is antigenic and may elicit a humoral or cell-mediated response like rapid buccal expansion of cyst.

533
Periapical cyst - Clinical Presentation
Rarely, parasthesia or pathologic jaw bone fracture may occur.
534
Periapical cyst - Clinical Presentation
Radiographically it is virtually impossible to differentiate granuloma from a cyst. If the lesion is large it is more likely to be a cyst. Radiographically both granuloma and cyst appear radiolucent, associated with the apex of non vital tooth.
535
Periapical cyst - Clinical Presentation
Intra Oral Peri Apical Radiographs i.e. IOPAs are common radiographs which are used as diagnostic aid from radiological point of view.
536
Periapical cyst - Clinical Presentation
Radiographically, Radicular Cysts are round or ovoid radiolucent areas surrounded by a narrow radio-opaque margin, which extends from Lamina Dura of involved tooth. In infected or rapidly enlarging cysts, radio-opaque margins may not be seen. Root resorption is rare but may occur.
537
Periapical cyst - Clinical Presentation
It is often difficult to differentiate radiologically between radicular cysts and apical granulomas.
538
Periapical cyst - Clinical Presentation
Radiologic presentation of Radicular Cyst is given in detail as follows:
539
Periapical cyst - Clinical Presentation
Periphery Shape--- Periphery usually have a well defined cortical border. If Cyst is secondarily infected, the inflammatory reaction of surrounding bone may result in loss of this cortex or alteration of cortex into more sclerotic border. The outline of radicular cyst usually is curved or circular unless it is influenced by surrounding structures such as cortical boundaries.
540
Periapical cyst - Clinical Presentation
Internal structure--- in most cases, internal structure of radicular cyst is radiolucent. Occasionally, dystrophic calcification may develop in long standing cysts appearing as sparsely distributed, small particulate radio-opacities.
541
Periapical cyst - Clinical Presentation
Effects on surrounding structures--- If a radicular cyst is large, displacement and resorption of roots of adjacent teeth may occur

Histopathological Features:-
543
Periapical cyst - Clinical Presentation
The gross specimen may be spherical or ovoid intact cystic masses, but often they are irregular and collapsed. The walls vary from extremely thin to a thickness of about 5mm. The inner surface may be smooth or corrugated. The histopathological studies shows following features ---
544
Periapical cyst - Clinical Presentation
The only exception to this is in those rare cases of periapical lesions of Maxillary Sinus
545
Periapical cyst - Clinical Presentation
2) Rushton’s Hyaline Bodies:- In approximately 10% of cases of radicular cysts, Rushton's Hyaline bodies are found in epithelial linings. Very rarely they are found in Fibrous capsule. The hyaline bodies are tiny linear or arc shaped bodies which are amorphous in structure, eosinophillic in reaction and Brittle in nature.
546
Periapical cyst - Clinical Presentation
3) Cholesterol Clefts:- Deposition of Cholesterol crystals are found in many radicular cysts, slow but considerable amount of cholesterol accumulation could occur through degeneration and disintegration of lymphocytes, plasma cells and macrophages taking part in inflammatory process, with consequent release of Cholesterol from their walls.
547
Periapical cyst - Clinical Presentation
4) Fibrous Capsule:- Fibrous Capsule of Radicular Cyst is composed of mainly condensed parallel bundles of collagen fibres peripherally and a loose connective tissue adjacent to epithelial lining.
548
Periapical cyst - Clinical Presentation
5) Inflammatory Cells:- Acute inflammatory cells are present when epithelium is proliferating. Chronic inflammatory cells are present in connective tissue immediately adjacent to epithelium.
549
Periapical cyst - Clinical Presentation
6) Mast cells, Remnants of Odontogenic Epithelium occasionally Satellite microcysts are also present. Some cysts are markedly vascularised. Various kinds of Calcifications are also present.

552
Periapical cyst - Treatment
The source (i.e., necrotic pulp) should be removed by full pulpectomy (i.e., root canal therapy) or tooth extraction|extraction of the offended tooth, and the cyst should be Enucleation (surgery)|enuclated.
553
Periapical cyst - Treatment
Peripheral lesions including radicular cysts are eliminated by body once the causative agents are removed. Majority of radicular cysts can undergo resolutions following Root Canal Treatment don't require surgical intervenation. It is suggested that insertion of file or other root canal instrument beyond the apical foramen (for 1-2mm) produces transitory acute inflammation which may destroy epithelial lining of radicular cyst and convert it into granuloma. Thus, leading to its resolutions.
554
Periapical cyst - Treatment
a) Enucleation- The affected tooth is extracted or preserved by root canal treatment with apicocetomy. A mucoperiosteal flap over cyst is raised and a window is opened in the bone to give adequate access. The cyst is carefully separated from its bony wall. The entire cyst is removed intact. the edges of bony cavity are smoothened off, free bleeding is controlled and cavity is irrigated to remove debris. Mucoperiosteal flap is replaced back and sutured in place.
555
Periapical cyst - Treatment
b) Marsupialisation- The cyst is opened essentially as for enucleation but the epithelial lining is sutured to mucous membrane at margins of opening
556
Periapical cyst - Treatment
Prognosis depends on particular tooth, the extent of bone destroyed and accessibility for treatment.
557
Periapical cyst - Treatment
1) Carcinomatous/Neoplastic Changes:-
558
Periapical cyst - Treatment
Squamous Cell Carcinoma or Epidermoid Carcinoma may occasionally arise from epithelial lining of Radicular Cyst.
559
Periapical cyst - Treatment
2) Pathologic Jaw Fracture:-
560
Periapical cyst - Treatment
If Cyst have completely eroded the bone specially if it is present in posterior region which is very rare in case of Radicular Cyst it may cause pathologic jaw bone fracture.
561
Periapical cyst - Treatment
Cyst may get secondarily infected and create further complications.

Bužim - Apiculture Apiculture should be given more attention because honey as the main bee product is irreplaceable in nutrition
563
Bužim - Apiculture No application has been submitted for subvention for honey production, because for submission of the application, pursuant to the Law on Primary Agricultural Production Support, it was necessary to submit the receipt of purchase or sale together with other necessary receipts.
564
Bužim - Apiculture The guidelines for development of apiculture are as follows: to enable selling of bee products both in and out of the country, pursue activities to increase the production of honey, pollen and other bee products.
