New non-surgical autopsy technique set to revolutionize post-mortem practice (March 4, 2011) -- A new non-surgical post-mortem technique that has the potential to revolutionize the way autopsies are conducted around the world has been pioneered by forensic pathologists and radiologists. ... > full story

Possible new treatment strategies for pancreatic cancer (March 4, 2011) -- Researchers have identified a protein that can be modified to improve the effectiveness of one of the most common drugs used to treat pancreatic cancer. ... > full story

Feet first? Old mitochondria might be responsible for neuropathy in the extremities (March 4, 2011) -- The burning, tingling pain of neuropathy may affect feet and hands before other body parts because the powerhouses of nerve cells that supply the extremities age and become dysfunctional as they complete the long journey to these areas, scientists suggest in a new study. The finding may eventually lead to new ways to fight neuropathy, a condition that often accompanies other diseases including HIV/AIDS, diabetes and circulatory disorders. ... > full story

Some overweight adolescents may be at risk for weak bones (March 4, 2011) -- Overweight adolescents already struggling with risk factors such as insulin resistance may need to add weak bones to their list of health concerns, researchers report. A study of 143 overweight 14- to 18-year-olds showed those with risk factors such as the precursor for diabetes and low levels of the blood-vessel protecting HDL cholesterol have less bone mass -- an indicator of bone strength -- than their overweight but otherwise healthy peers, according to new research. ... > full story

Constant race-based discrimination can lead to 'racial battle fatigue' for African-Americans (March 4, 2011) -- Just as the constant pressure soldiers face on the battlefield can follow them home in the form of debilitating stress, African-Americans who face chronic exposure to racial discrimination may have an increased likelihood of suffering a race-based battle fatigue, according to researchers. ... > full story

Star-shaped brain cells feed long-term memory (March 4, 2011) -- Researchers have found that lactate, a type of energy fuel in the brain, plays a critical role in the formation of long-term memory. These findings have important implications for common illnesses like Alzheimer's disease, other neurodegenerative disorders, aging-related memory impairment and diabetes. ... > full story

Drop in temperature may explain the increase in dry eye suffering (March 4, 2011) -- Springtime may be just what the doctor orders for individuals suffering from dry eye condition, a disorder resulting from insufficient tear production or altered tear film composition.
