...its for patients. "The research we've done to date suggests that TORS has great potential to improve the way we treat head and neck cancer patients," said Bert O'Malley, Jr., MD, Chair of PENN's Department of Otorhinolaryngology/Head and Neck Surgery. "We believe this technology will have a dramatic impact on...

Researchers Closer To Helping Hearing-Impaired Using Stem Cells

... but not in adult tissues,?said Dr. Hashino. “This suggests that treating marrow-derived stem cells with these molecules before transplantation might greatly enhance the possibility that the process would result in development of specific sensory neurons.?/p> The research was published March 18 in the onl...

Researchers Identify Cause of Early Bird Sleep Disorder

...om tissue culture experiments with the second gene suggests the change causes a protein -- an enzyme called a kinase that is made by the gene - to be less active than normal. The lead author of the paper in Nature is Ying Xu, a member of the team in San Francisco. Other team members are at the University of ...

Asymptomatic HIV babies could use earlier treatment

...n the Journal of the American Medical Association, suggests that early treatment might be appropriate for at least some apparently healthy infected infants. “There is a significant difference in the likelihood of disease progression [with earlier treatment], even though there is only about a month separating...

15 generations of untrained jocks, couch potatoes show big physiological adaptations

The Cay Sal Bank is located on the edge of a narrow ocean channel that funnels water as well as larvae and plankton from throughout the Caribbean, in all li...

Research Reveals Functions Of Harmful Shellfish Pathogens

...cus in humans. A study of V. vulnificus in oysters suggests that strains virulent to humans may be more invasive to--and persistent in--oysters. The Dover center, a field location of the ARS Eastern Regional Research Center in Wyndmoor, Pa., also studies methods to detect norovirus and the hepatitis A virus ...

Leprosy genome tells story of human migrations, French researchers report in Science

...e genetic similarity between the different samples suggests that the bacterium's genome is exceedingly stable. "It seems that there was only a single source of the bacterium that was at the origin of this global pandemic," Cole said. Each of the four SNP combinations was most common in a certain geographic ...

Aircraft Cabin Ventilation Influences The Transmission Of Diseases In-flight

Mark Gendreau (Lahey Clinic Medical Centre, MA, USA) and colleagues reviewed data from studies looking at the transmission of diseases during commercial air travel. They found that while commerc...

Tsunami-damaged coral reefs should be left to recover naturally, say scientists

... many quick fixes on offer but scientific evidence suggests that in most cases these would not be a good use of scarce resources and could actually harm surviving reefs. We need to find a long-term, sustainable solution for restoration. "We're advocating a cleaning up of the debris in the majority of cases, s...

Research may provide new link between soft drinks and weight gain

...Research Center at UC's Genome Research Institute, suggests that the total amount of calories consumed when fructose is added to diets may not be the only explanation for weight gain. Instead, he said, consuming fructose appears to affect metabolic rate in a way that favors fat storage. "Our study shows how ...

"This suggests a beneficial effect in treatments that target primarily the underlying and presumably damage-inflicting nasal and sinus membrane inflammation, instead of the secondary bacterial infection that has been the primary target of treatments for the disease...

Ancient DNA helps clarify the origins of two extinct New World horse species

The study also suggests that all the North American caballines--traditionally classified as multiple species based on their diverse size--belong to the same species. Thus, only two horse lineages lived in North America during the Late Pleistocene, the stilt-legged horses an...

Does vitamin C help prevent or treat the common cold? Maybe not, after all.
