Scientists identify molecular structure of key viral protein

...on protein. The first was for the influenza virus, completed in 1994. While a lot of research is currently being conducted on the HIV fusion protein, its two structures -- and an understanding of how the protein works -- remain incomplete. "The protein we studied," explained Lamb, an Investigator for the Howa...

History of human cannibalism eats away at researchers

...st author on the study is Dr. Marta Soldevila, who completed her Ph.D. at the Universitat Pompeu Fabra and performed a substantial part of the sequencing work at DeCODE Genetics (Reykjavik, Iceland). ...

Suicide risk does not increase when adults start using antidepressants, study finds

...103 patients taking antidepressants, there were 31 completed suicides in the six months following the antidepressant prescription. That rate was not higher in the one month after the prescription than in subsequent months. The study also found that newer antidepressants were associated with a faster decline in...

Inflammation and drugs to control this activity studied in a variety of tumors sites

...ad a sigmoidoscopy showing no polyps. All subjects completed questionnaires that asked about ibuprofen use and each provided a blood sample. The scientists looked at the seven gene variants among the two groups. They found that four of seven variants were associated with an increased risk for advanced distal ...

Anti-inflammatory drug's potentially deadly side effect found to be rare

Scientists have completed an extensive study of more than 3,000 patients who received a promising anti-inflammatory drug, natalizumab, that was linked to three cases of a serious brain infection in large clinical trials halted in early 2005. The new study found no new cases ...

In-home sensors spot dementia signs in elderly

...formances are evaluated in a small number of tests completed in a limited amount of time. "In contrast, we're looking continuously at elders' activity in their own homes," Hayes said. "Since we're measuring a person's activity many times over a short period, we can understand their normal variability and ide...

High estrogen levels associated with dementia in older men

...ic and medical information. A total of 2300 men completed the study and 223 were diagnosed with incident dementia during the follow-up period. 134 men developed Alzheimer's disease, and 44 developed vascular dementia. The researchers used Cox regression analyses, adjusting for age and other covariates, to s...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...ining nanostructures were launched on the recently completed mission of the US space shuttle Discovery. On the Space Station, experiments will be performed to determine their longevity when exposed to the extreme stresses of the radiation and vacuum of outer space. Of the NASA mission, Brinker says, "Ordinar...

Survivors of childhood polio do well decades later as they age

...ons. They found modest declines. Each patient also completed questionnaires about symptoms of progressive weakness at the beginning and end of the study period. Though the majority complained of progressive weakness during the time they were studied, these symptoms did not correspond with their actual magnitud...

NHGRI announces latest sequencing targets

.... The genome of Saccharomyces cerevisiae was first completed in 1996 and is a primary model for studying variations in genomes that can contribute to health and disease. The genomic data provided by this effort will allow researchers to develop basic tools to better understand human variation, such as distingu...

Novel therapy combinations gain ground in treating hepatitis

...s a control group. For the 162 patients who have completed the trial period at 24 weeks, results show that the two higher-dose combination arms had much better response rates than the control group, experiencing on average a 2.5 to 3.0 log decrease in hepatitis RNA reductions by week 24, a significantly bett...

New GI technologies improve internal organ visualization

...ermine the level of sedation. All procedures were completed successfully and six patients had at least one polyp removed. Of the 24 patients, 14 (7 colonoscopy and 7 endoscopy) lost responsiveness to ARM during the procedure. One subject experienced oxygen desaturation (level of breathing and sedation) belo...

When the going gets tough, slime molds start synthesizing

... unusual type III PKS genes following the recently completed final assembly and annotation of the entire Dictyostelium genome, which was carried out by a worldwide collaboration of many scientists, including the Kay group. Working independently, Saito and Kay had deleted the Dictyostelium gene for Steely2. ...

T cells activated to fight HIV basis for dendritic cell therapeutic vaccine

... Drug Administration. The researchers have already completed a similar trial in 18 patients that proved the approach is safe. In that trial, the vaccine was derived using a readily available HIV protein. Even with this somewhat generic approach, T cell immunity was enhanced. "Quite likely, it will be a comb...

Quitting smoking improves lung function considerably

...e 10 subjects who successfully stopped smoking and completed the six-week study, five used nicotine patches, one employed acupuncture and four quit without any aid. The researchers believe that their findings highlight the importance of smoking cessation for adults with asthma. ...
