| Posted: 31 Dec 2012 03:06 PM PST As if space travel was not already filled with enough dangers, a new study shows that cosmic radiation -- which would bombard astronauts on deep space missions to places like Mars -- could accelerate the onset of Alzheimer's disease.  |
| Direct evidence for receptor's role in synapse development Posted: 31 Dec 2012 01:10 PM PST Researchers have provided direct evidence that a specific neurotransmitter receptor is vital to the process of pruning synapses in the brains of newborn mammals. Faulty pruning at this early developmental stage is implicated in autism-spectrum disorders and schizophrenia. The definitive evidence for N-methyl-D-aspartate receptor in pruning has eluded researchers until now.  |
| Economic environment during infancy linked with substance use, delinquent behavior in adolescence Posted: 31 Dec 2012 01:10 PM PST The larger economic environment during infancy may be associated with subsequent substance use and delinquent behavior during adolescence.  |
| Late-life depression associated with prevalent mild cognitive impairment, increased risk of dementia Posted: 31 Dec 2012 01:10 PM PST Depression in a group of U.S. Medicare recipients ages 65 years and older appears to be associated with prevalent mild cognitive impairment and an increased risk of dementia.  |
| Differences in generic pill characteristics may lead to interruptions in essential medication use Posted: 31 Dec 2012 01:10 PM PST Researchers have found that some patients who receive generic drugs that vary in their color are over 50 percent more likely to stop taking the drug, leading to potentially important and potentially adverse clinical effects.  |
| Paired CT scans catch chemo-killing of liver tumors in real time Posted: 31 Dec 2012 08:05 AM PST Using two successive pairs of specialized CT scans, a team of radiologists has produced real-time images of liver tumors dying from direct injection of anticancer drugs into the tumors and their surrounding blood vessels.  |
| Hydrogen peroxide vapor enhances hospital disinfection of superbugs Posted: 31 Dec 2012 08:05 AM PST Infection control experts have found that a combination of robot-like devices that disperse a bleaching agent into the air and then detoxify the disinfecting chemical are highly effective at killing and preventing the spread of multiple-drug-resistant bacteria, or so-called hospital superbugs.  |
