Preoperative blood typing may not be needed for some pediatric surgeries Posted: 23 Sep 2013 11:35 AM PDT Certain pediatric surgeries carry such low risk of serious blood loss that clinicians can safely forgo expensive blood typing and blood stocking before such procedures, suggest the results of a small study.

Sibling bullying: What's the big deal? Posted: 23 Sep 2013 09:40 AM PDT Sibling bullying is a type of violence that is prevalent in the lives of most children, but little is known about it. Researchers say the phenomenon has been overlooked.

Booster dose of new meningitis vaccine may be beneficial Posted: 23 Sep 2013 09:40 AM PDT A study of 4CMenB, a new vaccine to protect against meningitis B bacteria (which can cause potentially fatal bacterial meningitis in children), shows that waning immunity induced by infant vaccination can be overcome by a booster dose at 40 months of age.

First direct measurement of spinal cord myelin in multiple sclerosis Posted: 23 Sep 2013 09:38 AM PDT Scientists have developed a novel molecular probe detectable by PET imaging. The new molecular marker, MeDAS, offers the first non-invasive visualization of myelin integrity of the entire spinal cord at the same time.

Putting the spring back in broken hearts Posted: 23 Sep 2013 08:42 AM PDT For years, scientists have been trying to engineer cardiac tissue to patch up areas of the heart damaged by heart attacks. Now Tel Aviv University researchers have fabricated fibers shaped like springs that allow engineered cardiac tissue to pump more like the real thing. They say that, once tested in clinical trials, the use of these fibers will improve and prolong the lives of millions of people.

It takes a(n academic) village to determine an enzyme's function Posted: 23 Sep 2013 08:41 AM PDT Scientists have sequenced the genomes of nearly 6,900 organisms, but they know the functions of only about half of the protein-coding genes thus far discovered. Now a multidisciplinary effort involving 15 scientists from three institutions has begun chipping away at this mystery -- in a big way. Their work to identify the function of one bacterial protein and the biochemical pathway in which it operates will also help identify the functions of hundreds of other proteins.

How 'bad' cholesterol causes atherosclerosis in humans: Stem cells play a key role Posted: 23 Sep 2013 08:41 AM PDT Translational researchers are developing a richer understanding of atherosclerosis in humans, revealing a key role for stem cells that promote inflammation.

Explaination for increased asthma severity in children exposed to diesel exhaust from traffic Posted: 23 Sep 2013 08:41 AM PDT A new study shows that exposure to diesel exhaust particles from traffic pollution leads to increased asthma severity in children. Moreover, the study finds that this is due to increased blood levels of IL-17A, a protein associated with several chronic inflammatory diseases, in children with high diesel exposure.

Rising rates of severe and fatal sepsis during labor and delivery Posted: 23 Sep 2013 08:41 AM PDT Rates of severe sepsis and deaths from sepsis among US women hospitalized for delivery have risen sharply over the last decade.

Research uncovers gene's contribution to asthma susceptibility Posted: 23 Sep 2013 07:20 AM PDT New research has uncovered the role gene ORMDL3 plays in the disease asthma. ORMDL3, a gene recently linked to asthma susceptibility, has now been linked to the body's ability to recruit inflammatory cells during an airway allergic reaction.

Smartphones, tablets could provide universal access to medical monitoring Posted: 23 Sep 2013 07:20 AM PDT Do you have a smartphone in your pocket or purse? If so, you may be carrying the future of mobile medical monitoring technology, according to a new report.

How bacteria integrate autotransporters into their outer membrane Posted: 23 Sep 2013 07:20 AM PDT The bacterial outer envelope is densely packed with proteins that form small pores and facilitate the passage of nutrients, toxins and signaling molecules. Researchers now demonstrate how these transporter proteins are integrated into the outer membrane.

Walnuts in diet can improve endothelial functions for overweight adults Posted: 23 Sep 2013 07:19 AM PDT Medical researchers have found evidence suggestive that adding walnuts to one's diet can protect against diabetes and heart disease in at-risk individuals.

Sleep education helps families of children with autism Posted: 23 Sep 2013 07:15 AM PDT Parent sleep education is beneficial in improving sleep and aspects of daytime behavior and family functioning in children with autism spectrum disorders..

Patient heal thyself: Solution to treatment for chronic infections could lie in patient's blood Posted: 23 Sep 2013 06:31 AM PDT A recent discovery provides hope for a new personalized treatment strategy that could use a patient's own blood to treat infection. This could help treat millions of people living with chronic infections such as HIV, Hepatitis B or Hepatitis C.

Smile! New nanotube surface promises dental implants that heal faster and fight infection Posted: 23 Sep 2013 06:31 AM PDT A surface of TiO2 nanotubes could reduce the failure rate for dental implants, both by encouraging bone growth around the implant and by serving as a drug-delivery system for antimicrobial and anti-inflammatory substances.

Immune system fights infection with performance enhancement Posted: 23 Sep 2013 06:30 AM PDT Researchers have found that even our immune system is subject to performance enhancement, with our bodies giving immune cells the boost they need to ensure the best team is selected to fight infections.

Hunger pains Posted: 23 Sep 2013 06:30 AM PDT Binge-eating disorder, only recently designated as a diagnosis by the American Psychiatric Association in its official diagnostic manual of mental conditions, is associated with lifelong impairments comparable to those of bulimia nervosa, a long-established eating disorder with more dramatic symptoms.

Clinical trial strives to provide optimal care during high-risk pregnancies Posted: 23 Sep 2013 06:30 AM PDT Researchers are conducting a clinical trial to help determine the best timing of delivery in preterm pregnancies complicated by poor fetal growth. Preliminary results from the trial demonstrate better than expected health outcomes in this high-risk group of fetuses.

Functional disability high among newly diagnosed older breast cancer patients Posted: 23 Sep 2013 06:30 AM PDT Many older women with newly diagnosed breast cancer have difficulty accomplishing daily tasks, and African-Americans seem to be disproportionately affected.
