New approach for treating genetic muscle wasting disease shows promise in mice Posted: 06 Mar 2012 04:56 PM PST Scientists have discovered that a drug called fasudil can extend the average lifespan of mice with spinal muscular atrophy (SMA) from 30.5 days to more than 300 days, and increase the size of muscle fibers. SMA is the leading inherited cause of death in infants and toddlers, affecting approximately 25,000 people in Canada and the United States.

Responding to the radiation threat Posted: 06 Mar 2012 03:12 PM PST Researchers are developing a promising treatment for safely decontaminating humans exposed to radioactive actinides from a major radiation exposure event, such as a nuclear reactor accident or a "dirty bomb" terrorist attack. The treatment, which can be administered as a pill that can result in the excretion of approximately 90-percent of the actinide contaminants within 24 hours, has been advanced through the initial pre-clinical phases.

Basque roots revealed through DNA analysis Posted: 06 Mar 2012 03:12 PM PST The Genographic Project has announced the most comprehensive analysis to date of Basque genetic patterns, showing that Basque genetic uniqueness predates the arrival of agriculture in the Iberian Peninsula some 7,000 years ago. Through detailed DNA analysis of samples from the French and Spanish Basque regions, the team found that Basques share unique genetic patterns that distinguish them from the surrounding non-Basque populations.

Specific antibodies halt Alzheimer's disease in mice Posted: 06 Mar 2012 03:11 PM PST Antibodies that block the process of synapse disintegration in Alzheimer's disease have been identified, raising hopes for a treatment to combat early cognitive decline in the disease.

Vegetarian cutlet: New method to prepare a meat substitute Posted: 06 Mar 2012 10:18 AM PST It looks like a cutlet, it's juicy and fibrous like a cutlet, and it even chews with the consistency of a real cutlet -- but the ingredients are 100 percent vegetable. Researchers are using a new method to prepare a meat substitute that not only tastes good, but is also environmentally sustainable.

Scientists pinpoint how vitamin D may help clear amyloid plaques found in Alzheimer's Posted: 06 Mar 2012 10:18 AM PST Researchers have identified the intracellular mechanisms regulated by vitamin D3 that may help the body clear the brain of amyloid beta, the main component of plaques associated with Alzheimer's disease. The early findings show that vitamin D3 may activate key genes and cellular signaling networks to help stimulate the immune system to clear the amyloid-beta protein.

Influencing stem cell fate: New screening method helps scientists identify key information rapidly Posted: 06 Mar 2012 10:16 AM PST Scientists have developed a powerful analytical method that they have used to direct stem cell differentiation. Out of millions of possibilities, they rapidly identified the chemical and physical structures that can cue stem cells to become osteocytes, cells found in mature bone. Researchers can use the method, called nanocombinatorics, to build enormous libraries of physical structures varying in size from a few nanometers to many micrometers for addressing problems within and outside biology.

Most weight loss supplements are not effective Posted: 06 Mar 2012 10:16 AM PST Scientists have reviewed the body of evidence around weight loss supplements and has bad news for those trying to find a magic pill to lose weight and keep it off -- it doesn't exist.

New brain imaging and computer modeling predicts autistic brain activity and behavior Posted: 06 Mar 2012 10:16 AM PST New research provides an explanation for some of autism's mysteries and gives scientists clear targets for developing intervention and treatment therapies. Scientists used brain imaging and computer modeling to show how the brain's white matter tracts -- the cabling that connects separated brain areas -- are altered in autism and how these alterations can affect brain function and behavior.

Unnecessary induction of labor increases risk of cesarean section and other complications, study suggests Posted: 06 Mar 2012 10:15 AM PST A new study reveals that induction of labor at term in the absence of maternal or fetal indications increases the risk of cesarean section and other postpartum complications for the woman, as well as neonatal complications.

Gene therapy approach to grow blood vessels in ischemic limbs Posted: 06 Mar 2012 10:14 AM PST Scientists can offer new hope that people with atherosclerotic disease may one day be able to avoid limb amputation related to ischemia. New research suggests that the delivery of genes for two molecules naturally produced by the body, called "PDGF-BB" and "VEGF" may successfully cause the body to grow new blood vessels that can save ischemic limbs.

Exercise and caffeine change your DNA in the same way, study suggests Posted: 06 Mar 2012 10:12 AM PST When healthy but inactive men and women exercise for a matter of minutes, it produces a rather immediate change to their DNA. Perhaps even more tantalizing, the study suggests that the caffeine in your morning coffee might also influence muscle in essentially the same way.

With extra gene, mice are footloose and cancer free Posted: 06 Mar 2012 10:12 AM PST In a perfect world, we could eat to our heart's content without sacrificing our health and good looks, and now it appears that maybe we can. Mice with an extra dose of a known anti-cancer gene lose weight even as their appetites grow. Not only that, but according to new research, the animals also live longer, and that isn't just because they aren't getting cancer, either.

Blood pressure drug effective for treating PTSD-related nightmares, study suggests Posted: 06 Mar 2012 04:30 AM PST The blood pressure drug prazosin appears to be an effective treatment to curb post-traumatic stress disorder (PTSD)-related nightmares.

Microneedle vaccine patch boosts flu protection through robust skin cell immune response Posted: 06 Mar 2012 04:30 AM PST Recent research found that microneedle vaccine patches are more effective at delivering protection against influenza virus in mice than subcutaneous or intramuscular inoculation. A new, detailed analysis of the early immune responses helps explain why the skin is such fertile ground for vaccination with these tiny, virtually painless microneedles.

New H5N1 viruses: How to balance risk of escape with benefits of research? Posted: 06 Mar 2012 04:30 AM PST In the controversy surrounding the newly developed strains of avian H5N1 flu viruses, scientists and policy makers are struggling with one question in particular: what level of biosafety is best for studying these potentially lethal strains of influenza? Experts now argue their different views of how to safely handle H5N1 flu viruses.

Weekend smoking can damage your memory, study suggests Posted: 06 Mar 2012 04:29 AM PST People who smoke only at weekends cause as much damage to their memory as those who smoke on a daily basis, according to new research.

New insight into how 'chemical switch' that increases risk of stroke and heart disease risk is turned on Posted: 06 Mar 2012 04:29 AM PST Scientists investigating a 'biochemical switch' linked to strokes and heart disease claim to have made an advance in understanding how it is 'turned on'.
