Death by asexuality: IU biologists uncover new path for mutations to arise
Date: Sep-06-2013Ground-breaking new research from a team of evolutionary biologists at Indiana University shows for the first time how asexual lineages of a species are doomed not necessarily from a long, slow accumulation of new mutations, but rather from fast-paced gene conversion processes that simply unmask pre-existing deleterious recessive mutations...
Ground breaking research identifies promising drugs for treating Parkinson's - including the licenced drug ursodeoxycholic acid
Date: Sep-06-2013New drugs which may have the potential to stop faulty brain cells dying and slow down the progression of Parkinson's, have been identified by scientists in a pioneering study which is the first of its kind. Experts from the world leading Sheffield Institute for Translational Neuroscience (SITraN) conducted a large scale drugs trial in the lab using skin cells from people with this progressive neurological condition which affects one in every 500 people in the UK. The researchers tested over 2,000 compounds to find out which ones could make faulty mitochondria work normally again...
Nursing students lack effective role models for infection prevention: Study
Date: Sep-06-2013100 percent of student nurses surveyed observed lapses in infection prevention and control practices during their clinical placements, according to a British study published in the September issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC)...
Body weight influences both the physical and mental quality of life
Date: Sep-06-2013Scientists from the Institute of Health Economics and Health Care Management (IGM) and from the Institute of Epidemiology II (EPI II) discovered that weight gain leads to deterioration in physical health. Female study participants, however, experienced improved mental quality of life as their weight increased, a result that was observed even in women who were already overweight when the study began. For this study, Professor Dr...
Medicaid pays for nearly half of all births in the United States
Date: Sep-06-2013Medicaid paid for nearly half of the 3.8 million births in the United States in 2010 - an amount that has been rising over time, according to a report out today. The study, published in the September 2013 issue of the peer-reviewed journal Women's Health Issues, offers the most comprehensive information to date on Medicaid financing of births in each of the 50 states and nationally. The new data will help researchers gauge the impact of health reform on maternal and child health, the authors say...
Young people at higher risk for stroke
Date: Sep-06-2013Fifteen percent of the most common type of strokes occur in adolescents and young adults, and more young people are showing risk factors for such strokes, according to a report in the journal Neurology. Neurologist Jose Biller of Loyola University Medical Center is a co-author of the report, a consensus statement developed by the American Academy of Neurology. Between 532,000 and 852,000 persons ages 18 to 44 in the United States have had a stroke. U.S...
Can you predict complications with back surgery? Preoperative factors increase risk
Date: Sep-06-2013For older adults undergoing surgery for spinal stenosis, some simple indicators of poor preoperative health predict a high risk of major medical complications, reports a study in the September 1 issue of Spine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. In combination, these risk factors may help in identifying patients at increased risk of heart attack and other serious events after spinal stenosis surgery, according to the report by Dr Richard A. Deyo and colleagues of Oregon Health and Science University, Portland...
Brain wiring quiets the voice inside your head
Date: Sep-06-2013During a normal conversation, your brain is constantly adjusting the volume to soften the sound of your own voice and boost the voices of others in the room. This ability to distinguish between the sounds generated from your own movements and those coming from the outside world is important not only for catching up on water cooler gossip, but also for learning how to speak or play a musical instrument. Now, researchers have developed the first diagram of the brain circuitry that enables this complex interplay between the motor system and the auditory system to occur...
Stressful life events significantly raise the risk of falls in older men
Date: Sep-06-2013A study of around 5,000 older men has shown that stressful life events such as death of a loved one, or serious financial problems, significantly raised the risk of falls in the year following the incident. The research is published online in the journal Age and Ageing. Dr Howard A. Fink of the VA Medical Center in Minneapolis and colleagues conducted a study of 5,994 community-dwelling men over the age of 65 who were enrolled in the Osteoporotic Fractures in Men (MrOS) study in six locations across the United States...
What is glucosamine?
Date: Sep-05-2013Glucosamine is a naturally occurring substance found in the fluid around our joints. It is naturally present in animal bones, bone marrow, shellfish and fungi. Glucosamine plays a vital role in building cartilage and is commonly consumed as a supplement by people with arthritis, especially osteoarthritis. Glucosamine, especially glucosamine sulfate, is harvested from the shells of shellfish and put into dietary supplements. It can also be made in the laboratory...
