Molecular Link Between Inflammation And Cancer Discovered
A team led by biochemists at the University of California, San Diego has found what could be a long-elusive mechanism through which inflammation can promote cancer. The findings may provide a new approach for developing cancer therapies. Mood Lighting: Penn Researchers Determine Role Of Serotonin In Modulat
Researchers at the University of Pennsylvania School of Medicine have determined how serotonin decreases the body's sensitivity to light and that exposure to constant darkness leads to a decrease in serotonin levels in the brain of fruit flies. These findings suggest that serotonin may play a role in maintaining circadian rhythm, as well as modulating light-related disorders such as seasonal affective disorder (SAD). Erectile Dysfunction: Group Psychotherapy Can Help
Taking part in group psychotherapy can help men who have erectile dysfunction to overcome their problem, and adding sildenafil to group therapy was more effective that sildenafil alone. In addition, group psychotherapy was more effective than taking sildenafil on its own, a Cochrane systematic review has found. Mice Predict The Effectiveness Of Orally Taken Drugs
More than half of all orally-prescribed medications are broken down in the intestine and liver by an enzyme known as CYP3A before reaching their site of action. Researchers have now developed a mouse model for predicting the loss in available drug due to first-pass metabolism by CYP3A, providing a tool to help predict whether drugs being developed will work effectively if given orally. Rebooting the Ecosystem
Global warming is real. We did it. Now it's time to talk about repairs. By David Wolman from Wired magazine. Study Finds Enzyme Activity Promotes Rare Form Of Leukemia, Offers Pot
Scientists at the University of North Carolina at Chapel Hill have identified an enzyme that helps trigger the development of leukemia, a cancer of blood cells. The 10 Most Deadly Poisons
All your favorites are here: Anthrax, sarin, cyanide. But who's got the dose with the most? By Christopher Null from Wired magazine. New Test Could Keep Babies From Contracting Deadly Infections
Women are tested for group B streptococcus during pregnancy, but current screening methods can leave some babies at risk for contracting an infection from the bacterium. But the new test, which University of Florida researchers studied for several months as part of a clinical trial, allows health-care workers to quickly screen mothers during labor, improving the odds that babies will not be infected during delivery. Love At First Sight Of Your Body Fat
When we choose a partner for a relationship there may be many and complex reasons for our choice, but it has been known for many years that we tend to select people with characteristics similar to our own. For instance, tall people tend to marry other tall people, and we tend to marry within our own social class, within our own educational class, and within our own race. Scientists call this assortative mating. They have now revealed that we also choose partners with a similar body fatness to our own. Taking Aim With Nanoparticle PEBBLEs
In what sounds like a modern-day version of the David and Goliath story, University of Michigan scientists hope to slay a big killer with pebbles. In this case, the killer is not a fearsome giant, but a dreaded disease: cancer. And the pebbles are not the kind you hurl from slingshots; they're nanoscale polymer beads known as Photonic Explorers for Biomedical use with Biologically Localized Embedding (PEBBLEs).
