4 What is the significance of injury and toxicity? Tissues differ in their capacity for repair –Epithelial cells are continuously replaced –Nerve cells, in general, do not divide Organs also differ in their “safety factors” –All organs have some amount of excess capacity –With aging and injury, the excess capacity is lost, and this may lead to loss of function

10 Modified from: http://www.chrononhotonthologos.com/inactive/strokedr/hbothera.htm.. Area of dead tissue (Ischemic core) Ischemic penumbra where cells are irreversibly damaged. Cells in this region often undergo apoptosis in the hours after the stroke.

42 In this abdominal MRI scan, it is possible to see subcutaneous fat around the abdomen, surrounding abdominal muscles. Visceral fat is deeper inside the abdomen, surrounding internal organs.It is the visceral fat that secretes IL-6, strongly suggesting a mechanistic link to systemic inflammation. http://mednews.wustl.edu/tips/page/normal/8947.html

43 The women in this study did not gain weight, but they did have an increase in abdominal fat http://www.lipidsonline.org/slides/slide01.cfm?q=abdominal+fat&dpg=10
