Same Genes Act Differently in Males and Females

... example, the expression of genes involved in drug metabolism differed by sex. The findings imply that male and female livers function the same, but work at different rates. "Our findings in the liver may explain why men and women respond differently to the same drug," noted Lusis. "Studies show that aspirin ...

Genes Identified To Protect Heart Muscles

... (ROS). ROS are a natural by-product of the body's metabolism of oxygen and are known by scientists for their signaling role in cellular activity. The findings revealed that HO-1 exerted these remarkable protective effects by cooperating with another protective gene, Akt. The protective effect of HO-1 was dep...

Heart Has Enough Oxygen to Survive Hypothermia; CPR Crucial

...dvised. Body shuts down As the body cools, the metabolism slows, reducing the need for oxygen. Limited blood circulation is directed to vital organs, including the brain, heart and kidneys, but not to non-vital organs such as the muscles, skin and periphery.

MRIs Show Drug Treatment Slows Brain Deterioration on Road to Alzheimer's Disease

...ent). APOE 4 is a molecule involved in cholesterol metabolism and is a common genetic predisposition to Alzheimer’s disease. All humans have a form of APOE, but APOE 4, which is present in 25 percent of the population, raises the likelihood of amyloid plaques forming in the brain, an important part of the patho...
