Scientists Move Closer To Bio-engineered Bladders

Tuesday, July 31st, 2007
Researchers are using an understanding of the special cells that line the bladder, urothelial cells, to develop ways of restoring continence to patients with serious bladder conditions, including cancer. Scientists have found that if the bladder is damaged, these cells are able to rapidly regrow to repair the wound. The researchers hope to harness this property to engineer new bladders.

Altering A Protein Makes Mice Less Fearful

Tuesday, July 31st, 2007
A new study shows that loss or chemical inhibition of a protein, known as acid sensing ion channel protein, reduces innate fear behavior in lab animals, making normally timid mice relatively fearless. The findings might provide useful insight into anxiety disorders, and may even point the way to a new therapeutic target.

Marijuana Component Opens The Door For Virus That Causes Kaposi’s Sarcoma

Tuesday, July 31st, 2007
The major active component of marijuana could aid the Kaposi’s sarcoma virus in infecting cells and multiplying, according researchers at Harvard Medical School. They report that low doses of THC, equivalent to that in the bloodstream of an average marijuana smoker, could be enough to facilitate infection of skin cells and could even foster malignancy.

Rise Of Obesity Exacerbated By ‘Social Multiplier’ Effects

Tuesday, July 31st, 2007
According to a new study an individual’s body weight depends not just on physiology and economic circumstances, but also on average body weight of the population at large. The study is the first to quantitatively model body weight distribution based on the combined outcome of economic, biological and social influences.

Coffee Drinking Related To Reduced Risk Of Liver Cancer

Tuesday, July 31st, 2007
A new study on the relationship between coffee drinking and the risk of liver cancer (hepatocellular carcinoma) confirmed that there is an inverse association between coffee consumption and HCC, although the reasons for this relationship are still unresolved. There was a 41 percent reduction of HCC risk among coffee drinkers compared to those who never drank coffee.

Ibuprofen Restores Learning Ability In Rats With Liver Failure

Tuesday, July 31st, 2007
Cognitive impairment is one of the neurological effects in patients with hepatic encephalopathy (abnormal brain function due to severe liver disease). For the first time, a new study showed that treatment with an anti-inflammatory improves cognitive function in rats induced with chronic liver failure.
