Effects of aging in stem cells

...disagreement that the bodys maintenance and repair systems deteriorate with age, even as there is plenty of disagreement as to why. Stem cells combat the aging process by replenishing old or damaged cellsparticularly in the skin, gut, and bloodwith a fresh supply to maintain and repair tissue. Unfortunately,...

Identified main genetic variants involved in response to HIV

...ciated to 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 is needed. Nevertheless, HLA-B variation pre...

Molecular detectors may refine cancer treatment

... T-cell leukemia, a cancer that strikes the immune systems own protective cells. Our selective aptamers clearly confirm there are several subcategories of adult T-cell leukemia, said Weihong Tan, Ph.D., a UF Research Foundation professor of chemistry at the College of Liberal Arts & Sciences and a member o...

Obesity found to be a risk factor for multiple myeloma

...ed interleukin-6 (IL-6), which promotes the immune systems inflammation response. In obese people, this can cause an overproduction of IL-6, which in turn creates a cellular environment that sustains multiple myeloma. The IL-6 chemical pathway is one possible way obesity could influence the risk of developin...

Using a technique called microsatellite DNA fingerprinting, a team of researchers from the University of Alberta in Edmonton and the University of Quebec at Rimouski collect...

UCLA researchers show that culture influences brain cells

By explaining some of the precise biological workings of MDSCs in cancer the teams findings suggest why experimental cancer vaccines have to date been plagued by T-cell tolerance, a weakened rather than strengthened im...

Longest study finds reef fish need longer break

...unning study on how fish populations in coral reef systems recover from heavy exploitation, researchers from the Wildlife Conservation Society (WCS) and others have found that the fish can recover, but they need lots of time decades in some cases. The study appears in a recent edition of the journal Ecolog...

Satellite survey links tropical park fires with poverty and corruption

Perhaps the clearest examples of this systems limitations were a park in Costa Rica and two parks in Indonesia where active volcanoes triggered the MODIS fire detection algorithm, he said. With fire frequency data in hand, researchers developed a set of social and economic indicators reflecting ...

Internal clock, external light regulate plant growth

... "It's a nice, elegant mechanism for how these two systems interact," said Julin Maloof, assistant professor of plant biology at UC Davis, who is senior author on the paper. When the seedlings are grown in constant light, most growth occurs in the late afternoon. But when the plants were moved to a more na...
