In the SMART Study, researchers from more than 30 countries around the world randomly assigned 5,472 participants infected with HIV with a CD4+ cell count of more than 350 per cubic millimeter to the continuous use of antiretr...

Different strategies underlie the ecology of microbial invasions

...ndings show that the release of chemical toxins is superior as a resident strategy to repel invasions, whereas the release of parasites is superior as a strategy of invasion. ...

A silent pandemic: Industrial chemicals are impairing the brain development of children worldwide

...h may have reduced IQ scores above 130 (considered superior intelligence) by more than half and increased the number of scores less than 70. Today, it's estimated that the economic costs of lead poisoning in U.S. children are $43 billion annually; for methylmercury toxicity, $8.7 billion each year. "Other ...

Researchers seek to design first treatment for neuroAIDS

... know yet whether MLK or GSK-3b inhibitors will be superior to other treatment approaches," Dewhurst said. "We do know that new directions are needed because, despite ten years of trying, no research effort has yielded an approved HAD drug." ...

Uncovering DNA's 'sweet' secret

...re others - including homo-DNA - that are actually superior in that regard." Egli's structure also shows that homo-DNA has more flexibility in how the bases (rungs of the ladder) bind. The bases in normal DNA adhere to a somewhat strict binding scheme - guanine (G) binds with cytosine (C) and adenine (A) bi...

New test helps identify hepatitis C patients at high risk of developing cirrhosis

...risk gene patterns. "The Cirrhosis Risk Score was superior to the known clinical factors, such as alcohol consumption, in predicting the risk of developing cirrhosis," said Cheung. "This test allows both physicians and patients to make an intelligent decision about the urgency of beginning antiviral th...

Biologically inspired sensors can augment sonar, vision system in submarines

...undings, Liu said. "Although biology remains far superior to human engineering, having a man-made parallel of the biological system allows us to learn much about both basic science and engineering," Liu said. "To actively learn from biology at the molecular, cellular, tissue and organism level is still the ...

Neural bottleneck found that thwarts multi-tasking

...ateral frontal and prefrontal cortex, and also the superior frontal cortex, to process the two tasks at once. Both areas have been shown in previous experiments to play a critical role in cognitive control. "We determined these brain regions responded to tasks irrespective of the senses involved, they were...

Mutation improves memory, may lead to memory-enhancing pill

... that performs the phosphorylation reaction have a superior ability to remember new things under certain training conditions. “Those results led us to suspect that decreasing the phosphorylation of eIF2a enhanced memory storage,?Costa-Mattioli said. In an effort to validate their earlier findings, the r...

New technique will produce a better chromosome map

...mical than electron microscopy, with comparable or superior results. With a more accurate chromosome map, researchers will next use fluorescent immunostaining of proteins that bind to specific DNA sequences. These landmarks will help them tease out the relationship of the sequence to the physical structure...

Machine preservation may promote more organ sharing

...on, it may promote more sharing of organs; it is a superior means of preserving organs out of body and provides a way to assess the viability of the organ." Stratta said machine preservation has played an important role in the Medical Center’s success transplanting kidneys at the outer limits of the ECD ac...

Mule deer moms rescue other fawns

...the study's findings seem to point to mule deer as superior mothers, the motivation for looking out for other fawns is likely based not on altruism but on simple survival, said Lingle. "Having a rigid and aggressive response to the simple sound of a fawn distress call may ensure effective defence of a fema...
