No link found between viral infection and rapidly developing Type 1 diabetes in young children Posted: 06 May 2013 04:11 PM PDT Some of the earliest results from the Environmental Determinants of Diabetes in the Young (TEDDY) study - a major Europe-USA consortium exploring the causes of Type 1 diabetes in children -- has found no evidence for viral infection as a cause of the rapid-onset form of the condition.

New antiviral treatment could significantly reduce global burden of hepatitis C Posted: 06 May 2013 04:11 PM PDT Around 150 million people globally are chronically infected with the hepatitis C virus (HCV) -- a major cause of liver disease and the fastest growing cause of liver transplantation and liver cancer. New prevention strategies are urgently required as people are continuing to be infected with HCV. New findings reveal the impact of a new antiviral treatment that could potentially reduce HCV rates in some cities affected by chronic HCV prevalence by half over 15 years.

Millions pass up free health subsidy Posted: 06 May 2013 03:17 PM PDT Low-income Medicare beneficiaries with poorer cognitive abilities are less likely to enroll in the Low Income Subsidy program, which provides nearly free prescription drug coverage for low-income adults. The findings suggest that even when presented with a single dominant option in the form of free additional drug coverage, many seniors fail to act in their own economic interests.

Boosting 'cellular garbage disposal' can delay the aging process Posted: 06 May 2013 03:16 PM PDT Biologists have identified a gene, previously implicated in Parkinson's disease, that can delay the onset of aging and extend the healthy life span of fruit flies. This research has important potential implications for aging and disease in humans. The gene, Parkin, serves at least two vital functions. By increasing Parkin activity, the scientists extended the lifespan of the flies by more than 25 percent.

Critical link in mammalian odor detection identified Posted: 06 May 2013 01:12 PM PDT Researchers at the Monell Center have identified a protein that is critical to the ability of mammals to smell. Mice engineered to be lacking the Ggamma13 protein in their olfactory receptors were functionally anosmic – unable to smell. The findings may lend insight into the underlying causes of certain smell disorders in humans.

New cause for common lung problem Posted: 06 May 2013 10:24 AM PDT New research has found that in cases of lung edema, or fluid in the lungs, not only do the lungs fail to keep water out as previously believed, but they are also allowing water to pump in.

Scientists build a living patch for damaged hearts Posted: 06 May 2013 10:24 AM PDT Biomedical engineers have grown three-dimensional human heart muscle that acts just like natural tissue. This advancement could be important in treating heart attack patients or in serving as a platform for testing new heart disease medicines.

New Canadian guidelines for treating fibromyalgia Posted: 06 May 2013 10:24 AM PDT Physicians have published a review article to help family doctors diagnose and treat fibromyalgia. The article represents the first time researchers have published Canadian guidelines to help manage the condition.

Weight gain linked with personality trait changes Posted: 06 May 2013 08:40 AM PDT People who gain weight are more likely to give in to temptations but also are more thoughtful about their actions, according to a new study.

In vivo flexible large scale integrated circuits developed Posted: 06 May 2013 08:39 AM PDT A team of researchers in Korea has developed in vivo silicon-based flexible large scale integrated circuits for bio-medical wireless communication.

Common treatment for bronchiolitis ineffective at reducing length of hospital stay, study suggests Posted: 06 May 2013 08:39 AM PDT New research shows that hospital stays for infants diagnosed with bronchiolitis, or inflammation of the lungs, and treated with nebulized 3% hypertonic saline (HS), a commonly used, off-label therapy, were not shorter than hospital stays for infants who received normal saline solution. Both treatments are liquid salt solutions that are vaporized and administered through a mask; however HS has a greater salt concentration and is believed to more effectively hydrate the air passages, decrease fluid accumulation and improve lung function.

Ubiquitous engineered nanomaterials can cause lung inflammation: Substances are used in everything from paint to sporting equipment Posted: 06 May 2013 07:33 AM PDT Scientists have found that breathing ultrafine particles from a large family of materials that increasingly are found in a host of household and commercial products, from sunscreens to the ink in copy machines to super-strong but lightweight sporting equipment, can cause lung inflammation and damage.

Commands from the matrix: Cellular environment controls formation and activity of neuronal connections Posted: 06 May 2013 07:29 AM PDT Environment moulds behavior -- and not just that of people in society, but also at the microscopic level. This is because, for their function, neurons are dependent on the cell environment, the so-termed extracellular matrix. Researchers have found evidence that this complex network of molecules controls the formation and activity of the neuronal connections.

Study provides clarity on supplements for protection against blinding eye disease Posted: 06 May 2013 06:56 AM PDT Adding omega-3 fatty acids did not improve a combination of nutritional supplements commonly recommended for treating age-related macular degeneration (AMD), a major cause of vision loss among older Americans, according to a new study. The plant-derived antioxidants lutein and zeaxanthin also had no overall effect on AMD when added to the combination; however, they were safer than the related antioxidant beta-carotene.

Nearly 20 percent of suicidal youths have guns in their home Posted: 06 May 2013 06:54 AM PDT Nearly one in five children and teens found to be at risk for suicide report that there are guns in their homes, and 15 percent of those at risk for suicide with guns in the home know how to access both the guns and the bullets, according to a new study.

Foster care a sound choice for some maltreated children Posted: 06 May 2013 06:54 AM PDT Newspaper articles, TV shows and books are filled with horror stories of children placed in foster care. A new study bucks that trend by showing out-of-home placements can improve the emotional health of some youths who have been maltreated by a parent.

Many parents multi-task while driving kids Posted: 06 May 2013 06:54 AM PDT Many parents are putting their precious cargo at risk while driving, according to survey results.

Research supports laws that require bicyclists to wear helmets Posted: 06 May 2013 06:54 AM PDT Bicycle helmets save lives and their use should be required by law. That's the conclusion of a new study.

High school athletes say concussions won't sideline them Posted: 06 May 2013 06:54 AM PDT Many high school football players say it's OK to play with a concussion even though they know they are at risk of serious injury, according to a new study.

Teen girls who exercise are less likely to be violent Posted: 06 May 2013 06:54 AM PDT Regular exercise is touted as an antidote for many ills, including stress, depression and obesity. Physical activity also may help decrease violent behavior among adolescent girls, according to new research.

Flame retardants, used in everyday products, may be toxic to children: Lower intelligence, hyperactivity seen Posted: 06 May 2013 06:54 AM PDT Chemicals called polybrominated diphenyl ethers have been used for decades to reduce fires in everyday products such as baby strollers, carpeting and electronics. A new study shows that prenatal exposure to the flame retardants is associated with lower intelligence and hyperactivity in early childhood.

The nocebo effect: Media reports may trigger symptoms of a disease Posted: 06 May 2013 06:53 AM PDT Expectation of negative effects can increase likelihood of experiencing symptoms, new research shows.

Possible treatment for serious blood cancer Posted: 06 May 2013 06:53 AM PDT A single antibody could be the key to treating multiple myeloma, or cancer of the blood, currently without cure or long-term treatment. New tests have shown that the antibody is able to destroy myeloma cells.

Endogenous antibiotic discovered in the brain Posted: 06 May 2013 06:52 AM PDT Scientists have discovered that immune cells in the brain can produce a substance that prevents bacterial growth: namely itaconic acid. Until now, biologists had assumed that only certain fungi produced itaconic acid.Scientists have now shown that even so-called microglial cells in mammals are also capable of producing this acid.

Activity of cancer inducing genes can be controlled by the cell's skeleton Posted: 06 May 2013 06:51 AM PDT Cancer is a complex disease, in which cells undergo a series of alterations, including changes in their architecture; an increase in their ability to divide, to survive and to invade new tissues or metastasis. A category of genes, called oncogenes, is critical during cancer progression, as they codify proteins whose activity favors the development of cancer. One of these molecules, Src, is implicated in a large number of human cancers. However, it is still not clear how healthy cells constrain its activity not to become tumorous. Researchers have now identified a novel mechanism by which the activity of Src is limited by the cell's skeleton (cytoskeleton) limiting the development of tumors.

Assembly of a protein degradation machine could lead to treatments in cancer, neurological diseases Posted: 06 May 2013 06:49 AM PDT Scientists have discovered new details about an assembly intricate process in cells and the proteins named chaperones that controls it. Their finding may advance treatments for cancer and neurological diseases.

Some prostate cancer patients more likely to die after weekend ER visits Posted: 06 May 2013 06:49 AM PDT Patients with prostate cancer that has metastasized, or spread, to other parts of the body face a significantly higher risk of dying when visiting a hospital emergency department on the weekend instead of on a weekday, according to researchers.

Oral drops can give kids needle-free relief from asthma, allergies Posted: 06 May 2013 06:49 AM PDT Allergy shots are commonly used to treat children with severe environmental allergies and asthma, but under-the-tongue drops may offer yet another beneficial — and stick-free — option for pediatric allergy sufferers, according to a review of existing scientific evidence.

Children living near toxic waste sites in developing countries may experience higher blood lead levels resulting in lower IQ Posted: 06 May 2013 06:48 AM PDT Researcher estimates that lead exposure could cause mental retardation in 6 in 1,000 children living near toxic waste sites.

Hospital surgical volume should be considered when judging value of procedures Posted: 05 May 2013 11:58 AM PDT The volume of cases performed at an institution each year has a direct effect on the outcome of surgical procedures, and should always be considered when looking at the benefits of a technique, according to a team of researchers.

Heroin vaccine blocks relapse, preclinical study suggests Posted: 03 May 2013 08:46 AM PDT Scientists have reported successful preclinical tests of a new vaccine against heroin. The vaccine targets heroin and its psychoactive breakdown products in the bloodstream, preventing them from reaching the brain.
