Genomic Analysis Uncovers New Targets for HIV Vaccine

...findings to aid the search for an HIV vaccine that would work by boosting the protective effects of one or more of these genes, and help the body's own immune system overcome an infection. One of the genes looks particularly attractive as a vaccine target. The study, published early online by the journal ...

One species, many genomes

...y designed DNA probes. "All together, these probes would have seven times the length of human genome," illustrates Weigel the extent of the project. The data were evaluated with several specially designed statistical methods, including a variant of machine learning. The result of this painstaking analysi...

Identified main genetic variants involved in response to HIV

...o genes encoding HLA-B and HLA-C molecular systems would explain up to 15% of viral load variation among patients, whereas the third genetic variation would explain 5.8% of these differences. Further study of other genetic regions involved in this process i...

Agent slows aging in mice

...xtend maximal lifespan by 20 or 30 percent, people would accept that as an important finding,” Miller says. No one excited by these early results in mice is advised to bulk up on creosote bush leaves as a way to defy old age. If NDGA pushes the aging envelope in the final results of this study, other la...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...its presence in the brains of Alzheimer’s patients would be assumed to be part of the problem. In the original development of his mouse, Shaftel worked closely with Stephanos Kyrkanides, D.D.S., Ph.D., associate professor in the Eastman Department of Dentistry and an expert on using a class of viruses k...

New study reports hotel guests at risk from carbon monoxide poisoning

...lifetime risk to individuals who 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 pois...

CSIRO scientists join fight to save 'Tassie devil'

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

Study shows big power of small RNAs, not just proteins, in halting cancer

...nding healthy cells. Most suspected that proteins would be revealed as key to the power of p53, but this latest research published June 6 by Nature now identifies miRNAs as a critical force behind the anti-proliferation potential of p53. Expression of most miRNAs is reduced in tumors, suggesting tha...

Columbine flowers develop long nectar spurs in response to pollinators

...h the longest tongues [to tap the flowers' nectar] would be favored by natural selection, and--in a never-ending process--continually drive the plants' spurs and the pollinator tongues to exceptionally long lengths." But it turns out, Whittall and Hodges found, that evolution acts in a more one-sided fa...

And that speed is what excites Dr. Gregersen. “We have the tools to get at these genes rather quickly now,” he said. “The more patients and controls that we have, the more power we will have to pull out new genes and make associa...
