A New Mechanism That Contributes To The Evolution Of Cancer
Date: Feb-04-2013This study, which involves the participation of CNIO researcher Oscar Fernandez-Capetillo, demonstrates the existence of new fragile genomic sites responsible for chromosomal alterations in tumors Cancer arises from the accumulation of mutations and structural changes in chromosomes, which in some cases give rise to combinations that favour the growth or expansion of the disease. In this context, chromosomes tend to lose or duplicate entire regions, although, the mechanisms that initiate these chromosomal abnormalities are not fully understood...
A 'Neurosteroid' Found To Prevent Brain Injury Caused By HIV/AIDS
Date: Feb-04-2013A team of scientists from Canada, Thailand and Morocco have found that DHEA-S may prevent neurocognitive impairment that affects a significant percentage of AIDS patients. In a report appearing in the February 2013 issue of The FASEB Journal, they describe how a network of steroid molecules found in the brain, termed "neurosteroids," is disrupted during HIV infection leading to brain damage. This suggests that treatment with one of these steroid molecules, called DHEA-S, may offset the disruption caused by the virus to prevent or reduce brain damage...
Easier Access To Eye Checks For Diabetics, Australia
Date: Feb-04-2013Improving access to vital eye checks for people with diabetes has been the focus of two Australian research groups. Diabetic retinopathy (DR) - blindness caused by diabetes -- remains a major cause of visual impairment in working-age Australians despite the availability of testing for early detection and treatment of the degenerative disease. Two new studies, published in the latest edition of the Medical Journal of Australia, investigate possibilities for improving the uptake of available testing in both rural and urban settings...
Discovery In Synthetic Biology Takes Us A Step Closer To New 'Industrial Revolution'
Date: Feb-04-2013The scientists, from Imperial College London, say their research brings them another step closer to a new kind of industrial revolution, where parts for these biological factories could be mass-produced. These factories have a wealth of applications including better drug delivery treatments for patients, enhancements in the way that minerals are mined from deep underground and advances in the production of biofuels...
One Of The Key Circuits In Regulating Genes Involved In Producing Blood Stem Cells Is Deciphered
Date: Feb-04-2013Researchers from the group on stem cells and cancer at IMIM (Hospital del Mar Medical Research Institute) have deciphered one of the gene regulation circuits which would make it possible to generate hematopoietic blood cells, i.e. blood tissue stem cells. This finding is essential to generate these cells in a laboratory in the future, a therapy that could benefit patients with leukaemia or other diseases who need a transplant and who, in many cases, do not have a compatible donor...
New Stroke Gene Discovery Could Lead To Tailored Treatments
Date: Feb-04-2013An international study led by King's College London has identified a new genetic variant associated with stroke. By exploring the genetic variants linked with blood clotting - a process that can lead to a stroke - scientists have discovered a gene which is associated with large vessel and cardioembolic stroke but has no connection to small vessel stroke. Published in the journal Annals of Neurology, the study provides a potential new target for treatment and highlights genetic differences between different types of stroke, demonstrating the need for tailored treatments...
Jocks Beat Bookworms On Brain Test
Date: Feb-04-2013Perception study reveals information that could eventually help people with cognitive problems English Premier League soccer players, NHL hockey players, France's Top 14 club rugby players, and even elite amateur athletes have better developed cognitive functions than the average university student, according to a perception study undertaken by Professor Jocelyn Faubert of the University of Montreal's School of Optometry. The study demonstrates a possible outcome of the increased cortical thickness that has been found in areas of trained athletes' brains...
Researcher Uncovers Potential Cause, Biomarker For Autism And Proposes Study To Investigate Theory
Date: Feb-04-2013A New York-based physician-researcher from Touro College of Osteopathic Medicine, best known for his research into fertility and twinning, has uncovered a potential connection between autism and a specific growth protein that could eventually be used as a way to predict an infant's propensity to later develop the disease. The protein, called insulin-like growth factor (IGF), is especially involved in the normal growth and development of babies' brain cells...
New Rules For School Snack Foods Announced In USA
Date: Feb-04-2013The USDA (US Department of Agriculture) released its long-awaited nutritional guidelines for snacks that are sold in schools, in an effort to address the growing problem of obesity and overweight among American school-age children. The US Department of Agriculture (USDA) announced that the public comment period has started on new proposed standards to make sure that kids have access to healthy foods at school...
Fraudulent Flu Products On The Rise
Date: Feb-04-2013Fraudulent flu products are on the rise and many places have begun selling supposed cures and treatments for the flu which do not actually work. The U.S. Food and Drug Administration (FDA) has recently issued a warning to the public about online and retail shops that are selling such products, advising people to steer clear of them. As soon as a health threat appears, scammers quickly try and sell their fraudulent products to a desperate public. With the severity of this year´s influenza, there is a growing number of alternatives to the flu vaccine that keep popping up...
