Scientists use gene transfer technology and common virus to block neuropathic pain

...amage showed much less pain-related behavior after receiving injections of the HSV-based vector, which contained a gene called GAD, or glutamic acid decarboxylase. The treatment's pain-killing effect lasted up to six weeks, and even longer in rats that received additional injections. The study is the first to...

Freeze-dried mats of microbes awaken in Antarctic streambed

The study showed the new microbial mats were taking up atmospheric nitrogen at a higher rate than mats in adjacent streambeds, increasing biomass productivity, she said. As photosynthetic bacteria, cyanobacteria ar...

Genomics researchers discover protein deficit that causes drug toxicity

...n really is, but it appears to play a role here by receiving misfolded proteins." Significance of the Research "Nobody has shown before that the aggresome plays a role in thiopurine metabolism, and it's a significant contribution," says Richard Weinshilboum, M.D., the Mayo Clinic researcher who first describ...

He called for increased resources, better planning, better and more vocal leadership, and real investment in the empowerment of women and girls. Women now accounted for about half of all people living with HIV worldwide, but they were also the...

Results of world's first gene therapy trial for arthritis show approach safe, feasible

Nicotine triggers the same brain reward circuitry as opiates

...ned mice to associate a specific test chamber with receiving nicotine, finding that the mice would prefer to stay in that chamber when given a choice. The researchers found that just placing the conditioned mice in the chamber activated CREB. They also found that naloxone blocked this conditioned increase in C...

After 5 more days had passed, a total of 84 percent of the misoprostol group had complete uterine expulsion. The misoprostol treatment failed for 16 percent of the group, however. In contrast, 3 per...

Study shows humans have ability to track odors, much like bloodhounds

...ts, 16 in all, were able to tell which nostril was receiving a squirt of scent, but anosmic volunteers could only localize the trigeminal odorants, Sobel said. This shows that humans are able to localize odors through the olfactory nerves alone. "One possible objection is that the experimental set-up, with a ...
