Bad air means bad news for seniors' brainpower Posted: 16 Nov 2012 01:10 PM PST Living in areas of high air pollution can lead to decreased cognitive function in older adults, according to new research.

Clues to cause of kids' brain tumors Posted: 16 Nov 2012 06:12 AM PST Insights from a genetic condition that causes brain cancer are helping scientists better understand the most common type of brain tumor in children.

Fetus suffers when mother lacks vitamin C Posted: 16 Nov 2012 05:56 AM PST Maternal vitamin C deficiency during pregnancy can have serious consequences for the fetal brain. And once brain damage has occurred, it cannot be reversed by vitamin C supplements after birth.

Fear of the dentist is passed on to children by their parents Posted: 16 Nov 2012 05:55 AM PST The father acts as an intermediary for dentist fear between both mother and children. Fear of visiting the dentist is a frequent problem in pediatric dentistry. A new study confirms the emotional transmission of dentist fear among family members and analyses the different roles that mothers and fathers might play.

Into the magnetic resonance scanner with a cuddly toy Posted: 16 Nov 2012 05:55 AM PST Clinicians have been able to show on the basis of a large sample, that it is possible to examine children's heads in the MRI scanner without general anesthesia or other medical sedation. In many cases it was sufficient to prepare the young patients for the examination in an age-appropriate manner in order to take away their fear of the tube. And the results speak for themselves: of the 2461 image sequences recorded with 326 patients, the participating radiologists classified 97 percent as "diagnostically relevant."

Location, location, location: Membrane 'residence' gives proteases novel abilities Posted: 16 Nov 2012 05:53 AM PST Scientists have discovered a new mode of action for enzymes immersed in cellular membranes. Their experiments suggest that instead of recognizing and clipping proteins based on sequences of amino acids, these proteases' location within membranes gives them the unique ability to recognize and cut proteins with unstable structures.

Arthritis study reveals why gender bias is all in the genes Posted: 15 Nov 2012 06:05 PM PST Researchers have pieced together new genetic clues to the arthritis puzzle in a study that brings potential treatments closer to reality and could also provide insights into why more women than men succumb to the disabling condition.

Medical vital-sign monitoring reduced to the size of a postage stamp Posted: 15 Nov 2012 11:14 AM PST Electrical engineers have developed new technology to monitor medical vital signs, with sophisticated sensors so small and cheap they could fit onto a bandage, be manufactured in high volumes and cost less than a quarter.

Transporting hypothermia victims to advanced heart and lung care facilities 'worth the trip' Posted: 15 Nov 2012 10:38 AM PST Hypothermia victims whose hearts have stopped functioning should be transported to a medical facility with advanced heart and lung support equipment, even if that means longer travel time, according to a new study.

Study shows different approach after progression in non-small cell lung cancer patients Posted: 15 Nov 2012 10:37 AM PST A new study shows that other approaches to overcome acquired resistance should be considered.

Study reveals insights that could aid in therapeutic use of mesenchymal stem cells Posted: 15 Nov 2012 10:37 AM PST Research reveals new insights into how mesenchymal stem cells "traffic" from the circulation into the tissue, providing important clues that could be used to improve the delivery of this promising therapy.

Surprising genetic link between kidney defects and neurodevelopmental disorders in kids Posted: 15 Nov 2012 10:23 AM PST About 10 percent of kids born with kidney defects have large alterations in their genomes known to be linked with neurodevelopmental delay and mental illness, a new study has shown.

Month of birth effect: Give pregnant women vitamin D supplements to ward off multiple sclerosis, say researchers Posted: 14 Nov 2012 04:26 PM PST The risk of developing multiple sclerosis is highest in the month of April, and lowest in October, indicates an analysis of the available evidence, published online in the Journal of Neurology Neurosurgery and Psychiatry.
