LIAI completes world's most comprehensive analysis on influenza virus data

...y be possible to develop an influenza vaccine with greater cross protection for many different viruses." Sette said the study found hundreds of similar epitopes among the different virus strains. However, it remains to be seen whether these epitopes are similar enough to enable the successful development ...

OHSU surgeon implants donated tissue allografts

... Services, which has been serving Portland and the greater Oregon community for decades, and the tissue preparation and coordination resources of the Joint Restoration Foundation has already proven valuable. Several OHSU patients have recently benefited directly from the increased availability of fresh tissu...

Woman's Day and For Womens of Science

...nomic costs of mercury pollution are probably much greater than estimated because existing economic analyses don't consider mercury's impacts on ecosystems and wildlife. The concentration of methylmercury in fish in freshwater and coastal ecosystems can be expected to decline with reduced mercury inputs; h...

'Marathon mice' elucidate little-known muscle type

...GC-1â animals with more IIX muscle fibers showed a greater capacity for aerobic exercise, they found. Transgenic mice were able to run, on average, for 32.5 min to exhaustion, compared to 26 min for their normal littermates, Spiegelman's group reported. "These data have potential importance for the therap...

Mercury contamination of fish warrants worldwide public warning

...nomic costs of mercury pollution are probably much greater than estimated because existing economic analyses don't consider mercury's impacts on ecosystems and wildlife. The concentration of methylmercury in fish in freshwater and coastal ecosystems can be expected to decline with reduced mercury inputs; h...

Remote sheep population resists genetic drift

... and female couple can produce. Scientists believe greater genetic diversity corresponds with greater odds of survival and successful reproduction due to a greater variety of genetic tools an organism h...

Lithium builds gray matter in bipolar brains, UCLA study shows

... examine differences in cortical anatomy at a much greater spatial resolution. In this study, Bearden and colleagues at UCLA used computer analysis to analyze brain scans collected by collaborators at the University of Pittsburgh in order to determine whether bipolar patients showed changes in brain tiss...

Anthrax attack posed greater potential threat than thought

...side the building; the extent of exposure was thus greater than predicted. No associations were seen between exposure levels and immune responses or symptoms, but the most-exposed subjects were the only ones to have high-magnitude responses. Low-level exposure did not appear to trigger an antibody response, ...

Robotic therapy helps restore hand use after stroke

...ute. The patients also developed a 17 percent greater range of motion in their hands and wrists and were rated as less disabled on a standard occupational therapy assessment tool called the Fugl-Meyer score. __IMAGE_3 "Assessing changes in before-and-after scores within each subject, these were hig...

Chemo combination improves survival in asbestos-related cancer

...bestosis, which is a nonmalignant condition, and a greater lag before the development of overt malignancy." "There is no way of diagnosing the premalignant phase during the latent period of 15 to 20 years," Green added. "Many of these patients smoke and are in economically disadvantaged communities. Many...

Molecular differences between early and advanced melanomas could provide new drug targets

.... The scientists also found that in cells with greater Akt expression, there was an increase in impaired mitochondria-- the energy factories of cells. Their research showed, however, that these mutations in mitochondria were likely the result of the prolonged exposure to increased oxidative stress caused...

Saving endangered whales at no cost

...that the number of traps used in Maine is 13 times greater than in the Canadian Fishing Area to harvest the same lobster catch. On the basis of these findings and estimations of seasonal whale presence determined by patterns of whale sightings, the authors estimate that, in terms of impact on right whales, e...

Researchers discover gene crucial for nerve cell insulation

...ion in the peripheral nervous system could lead to greater understanding of how myelination takes place in the central nervous system (the brain and spinal cord). Myelination in the central nervous system is not well understood. Multiple sclerosis, a degenerative muscular disorder that can be fatal, results...

20-year study shows significant rise in childhood obesity, especially among girls

..., however, that the weight data was missing from a greater percentage of the 16 year-olds' records in 2002 and this could be because some of the more overweight teenagers refused to be weighed." Key findings included: In 2002, about a fifth of four-year-olds - 22 per cent of girls and 18 per cent of ...

Study identifies risk factors for spread of respiratory infections in hospitals

...acilities decreased the risk. The risk was greater when high flow oxygen therapy and positive airway pressure ventilation was used. These lessons can be applied to controlling other respiratory disease outbreaks in hospitals. ...

Dual gene therapy suppresses lung cancer in preclinical test

...ther analysis showed that the combination achieved greater cell suicide because FUS1 suppresses a gene that expresses a protein known to rapidly degrade p53, says senior author Lin Ji, Ph.D., M. D. Anderson associate professor of thoracic and cardiovascular surgery. The FUS1/p53 combination also activate...

New research says winning a Nobel Prize adds nearly 2 years to your lifespan

...itive effect of "status" from the effect of simple greater wealth that status often brings. Nobel Prize winners were viewed as an ideal group to study as the winners could be seen as having their status suddenly dropped on them. They also come with a ready made control group they can be directly measured aga...

Ethanol vehicles pose a significant risk to human health, study finds

...how that a high blend of ethanol poses an equal or greater risk to public health than gasoline, which already causes significant health damage.'' Gasoline vs. ethanol For the study, Jacobson used a sophisticated computer model to simulate air quality in the year 2020, when ethanol-fueled vehicles are...

Elderly spinal cord injuries increase five-fold in 30 years, Jefferson neurosurgeons find

...tigators. "The mortality of these patients is much greater than younger patients and should be factored in when considering aggressive interventions and counseling families regarding prognosis." However, they also found that these patients have had an increase in survival over this period. A...

Antivirals effectively curb influenza virus

...cts. In exploring the reasons for oseltamivir's greater effects on infectiousness, the authors speculated that the different modes of administration ?oral for oseltamivir and inhaled for zanamivir ?and resultant upper-respiratory viral levels could be the key, with zanamivir not reaching or affecting infl...
