Genomic Analysis Uncovers New Targets for HIV Vaccine

...use. "This study was the first time a genome-wide approach has been used for an infectious disease," Goldstein said. "Past studies have looked at individual candidate genes. Since different people respond differently to infections, a better understanding of how immune system genes control responses to infect...

FDA sees nanotech challenges in every product category it regulates

...echnology Task Force about the agency’s regulatory approach toward nanotechnology—an exciting new field of engineering and science that is estimated to grow to $2.6 trillion in manufactured goods globally by 2014. As the Task Force report highlights, nanotechnology impacts every area of FDA responsibility—dru...

Blood test may help signal tumor's remission, return in throat cancer patients

...le of the predictive, preemptive, and personalized approach to medicine that the NIH strives for.” Roughly 20 years ago, the primary method for treating throat cancer was to surgically remove the tumor. Because this treatment can severely impair a patient’s quality of life by damaging voice, speech, and sw...

Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

... or neurturin presents a potentially important new approach for the treatment of ED. "Because the herpes virus persists in the nerve cell for as long as it is alive and nerve cells typically do not reproduce, this represents the first-ever demonstration of a long-term treatment for ED that does not rely on th...

Modeling the restless brain

...ity of the brain at rest. With their computational approach -- which involved creating a large-scale computer model of the brain of a macaque monkey -- they demonstrated that the shape and pattern of the fluctuations are determined by the brain's wiring diagram, its neuroanatomy. Their model also can show...

New study reports hotel guests at risk from carbon monoxide poisoning

...travel frequently would be higher. This risk could approach zero with effective CO prevention measures.” The authors contacted 43 sites where CO poisonings had occurred and found that only 12% had installed CO detectors after the incidents. In 101 sites where no CO poisoning had occurred, only 11 % had in...

Studies to find better ways to preserve human eggs, ovarian tissue under way

Progress toward an antitumor vaccine

...cal antitumor therapy. The difficulty with this approach is that such sugar-containing compounds are completely ineffective at stimulating the immune system to form antibodies. “Immunization is only successful if the vaccine is anchored to an immunizing carrier protein by means of a spacer,” explains Kunz....

New findings challenge established views on human genome

...the success of this effort. No single experimental approach can be used to identify all functional elements in the genome. So, it was necessary to conduct multiple, diverse experiments and then analyze them using multiple computational methods,” said Elise A. Feingold, Ph.D., program director for ENCODE in NH...

University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts

...re similar to that in humans. The advantage of our approach is that the graft could utilize the patient’s own stem cells and be ready for implantation almost immediately or, at most, after a relatively short culture period. This suggests that we could make these available ‘off-the-shelf,’ which is an essentia...

Gene therapy study shows safety and statistically significant improvement in Parkinson's disease

...g first step in the development of a promising new approach to Parkinson’s disease therapy, but also provides a platform to translate a variety of new gene therapy agents into human clinical trials for many devastating brain disorders,” said Paul Greengard, PhD, chairman of the Neurologix Scientific Advisory ...

Ice Age extinction claimed highly carnivorous Alaskan wolves

This multifaceted approach allowed the researchers to trace the ancient wolves’ genetic relationships with modern-day wolves, as well as understand their role in the ancient ecosystem. “Being able to say all of those things—having a complete picture—is really unusual,” sai...

Skimmed milk -- Straight from the cow

...cal director at Dairy UK says that the New Zealand approach could be used to breed cows that still produce full-fat milk but with only the good fats, which could swing things back in favour of full-fat milk. In the UK, for example, only 25% of milk sold is full fat. ‘In future if whole milk can be made to co...
