Study Of Tiny Roundworms Provides Clue To Observed Human Health Benefits From Omega Fatty Acids
Date: Feb-17-2013A search for genes that change their levels of expression in response to nutrient deprivation has uncovered potential clues to the mechanism underlying the health benefits of omega fatty acids. In the journal Genes & Development, Massachusetts General Hospital (MGH) researchers describe finding that feeding omega-6 fatty acids to C. elegans roundworms or adding them to cultured human cells activates a cellular renewal process called autophagy, which may be deficient in several important diseases of aging...
Medical Professionals Should Consider How Marital Quality Affects Patients' Health
Date: Feb-17-2013Research shows that married people have better mental and physical health than their unmarried peers and are less likely to develop chronic conditions than their widowed or divorced counterparts. A University of Missouri expert says that people who have happy marriages are more likely to rate their health as better as they age; aging adults whose physical health is declining could especially benefit from improving their marriages...
Genes Activated For Human Speech Similar To Ones Used By Singing Songbirds
Date: Feb-17-2013The genes activated for human speech are similar to the ones used by singing songbirds, new experiments suggest. These results, which are not yet published, show that gene products produced for speech in the cortical and basal ganglia regions of the human brain correspond to similar molecules in the vocal communication areas of the brains of zebra finches and budgerigars. But these molecules aren't found in the brains of doves and quails - vocal birds that do not learn their sounds...
Hemodiafiltration Prolongs Dialysis Patients' Lives
Date: Feb-17-2013A technique that removes additional toxins during dialysis may prolong kidney failure patients' lives, according to a clinical trial appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). In light of these results, the technique may become standard for dialysis patients...
More Americans Meeting Diabetes Goals
Date: Feb-17-2013The number of Americans meeting their diabetes goals - blood sugar, blood pressure and cholesterol - has increased considerably over a 12-year period, says a new study by the NIH (National Institutes of Health) and CDC (Centers for Disease Control and Prevention) and published in Diabetes Care. The authors wrote that from 1988 to 2010, the proportion of diabetes patients in the USA who exceeded or met the three measures that demonstrate good diabetes management increased from approximately 2% to 19%. Each measure, the researchers added, showed significant improvement...
Sexual Reproduction And Clues To Chromosome Crossovers
Date: Feb-17-2013Neil Hunter's laboratory in the UC Davis College of Biological Sciences has placed another piece in the puzzle of how sexual reproduction shuffles genes while making sure sperm and eggs get the right number of chromosomes. The basis of sexual reproduction is that a fertilized egg gets half its chromosomes from each parent - sperm and eggs each contributing one partner in each pair of chromosomes. We humans have 23 pairs of 46 chromosomes: so our sperm or eggs have 23 chromosomes each...
Fighting Necrotizing Enterocolitis With Probiotic-Derived Treatment In Premature Babies
Date: Feb-17-2013"Good" bacteria that live in our intestines have been linked with a variety of health benefits, from fighting disease to preventing obesity. In a new study, Kriston Ganguli of Massachusetts General Hospital for Children and Harvard Medical School and her colleagues have discovered another advantage to these friendly microscopic tenants: Chemicals secreted by good bacteria that typically live in the intestines of babies could reduce the frequency and severity of a common and often-lethal disease of premature infants...
Brain Location For Stem Cell Transplantation Crucial For Cell Survival
Date: Feb-16-2013Researchers at the Johns Hopkins University in Baltimore, Md., and the Mossakowski Medical Research Centre in Warsaw, Poland, have found that nonself-donated cells (allografts) better survive implantation into the brains of immunocompetent research mice when the grafts are injected into the striatum (STR) of the brain rather than injected into the forceps minor (FM) region. In their study, all FM grafts were rejected while STR grafts accumulated and survived along the border between the striatum and the corpus callosum...
FDA Approval And Launch Announced Of Advisa DR MRI™ SureScan® Pacing System
Date: Feb-16-2013Showcasing its leadership position in pacing technologies, Medtronic, Inc. (NYSE: MDT), has announced the U.S. Food and Drug Administration (FDA) approval and U.S. launch of its Advisa DR MRI™ SureScan® pacing system. The Advisa MRI system is Medtronic's second-generation MR-Conditional pacemaker and is the first system to combine the most advanced pacing technology with proven MRI access. MRI is the standard of care in soft tissue imaging, providing information not seen with X-ray, ultrasound or CT scans, and is critical for early detection, diagnosis and treatment...
Clinicians Are Likely Missing Alcohol Problems By Not Asking The Right Questions
Date: Feb-16-2013By relying on hunches rather than posing a few screening questions, primary care clinicians may be missing three quarters of the alcohol problems in their patients, a newly released analysis shows. "It's often off the radar - people come in for hypertension and are not asked how much they drink," said study co-author Barbara J. Turner, M.D., M.S.Ed., M.A., M.A.C.P., of UT Medicine San Antonio. Primary care offices typically don't have good systems to administer questionnaires to screen for certain problems, including alcohol consumption, she noted...
