Washington, April 3: Penn State researchers say that a naturally fluorescent molecule found in all living cells may serve as an indicator of cancer.

Ahmed Heikal, associate professor of bioengineering, points out that nicotinamide adenine dinucleotide (NADH) fuels a series of biochemical reactions that involve various enzymes to produce ATP, the major energy source in cells.

In the event of disease or a metabolic disorder, he adds, these enzymes and their related reactions can become disabled, causing a build-up of unused NADH.

Washington, Apr 3 : Treating diabetes with a class of drugs, called glitazone, leads to a "modest" increase in the risk of diabetic macular oedema (DME), which is a common vision-threatening complication, according to a study.

Washington, Apr 3 : Almost 60 percent of American college students have been in a "no commitment" and "no romance" sexual relationship with a friend, which is also touted as a "friends with benefits" relationship, according to a study.

Conducted by researchers at Wayne State University and Michigan State University, the study showed that the possibility for romantic feelings, and a lack of communication, could complicate such an arrangement.

The study focussed on why college students had such relationships at all.

Washington, Apr 3 : Women with a family history of breast cancer can reduce their risk of developing the disease through regular exercise, say researchers.

With the evidence that reducing estrogen in the body reduces cancer risk, and that elite female athletes experience a drop in estrogen levels that often cause them to stop ovulating and menstruating, University of Pennsylvania researchers are conducting further studies to understand whether reduce their risk.
