Risk Of Stillbirth May Be Increased By Stressful Life Events
Date: Apr-01-2013Pregnant women who experienced financial, emotional, or other personal stress in the year before their delivery had an increased chance of having a stillbirth, say researchers who conducted a National Institutes of Health network study. Stillbirth is the death of a fetus at 20 or more weeks of pregnancy. According to the National Center for Health Statistics, in 2006, there was one stillbirth for every 167 births. The researchers asked more than 2,000 women a series of questions, including whether they had lost a job or had a loved one in the hospital in the year before they gave birth...
Sex Discrimination In Prenatal Care
Date: Apr-01-2013Women in India are more likely to get prenatal care when pregnant with boys, according to groundbreaking research that has implications for girls' health and survival. The study by Leah Lakdawala of Michigan State University and Prashant Bharadwaj of the University of California, San Diego, suggests sex discrimination begins in the womb in male-dominated societies. "It paints a pretty dire picture of what's happening," said Lakdawala, MSU assistant professor of economics...
Cell Transplantation And Brain Repair Impacted By Environmental Enrichment
Date: Apr-01-2013A team of Korean researchers investigated whether "environmental enrichment" can improve the neurobehavioral function of six week-old mice after transplantation of adipose-derived stem cells (ASCs) to treat hypoxic-ischemic brain injury, and found that brain repair (neurogenesis) was aided in some animals through exercise-induced fibroblast growth factor 2 (FGF2), a strong pro-angiogenic factor. The post-transplantation environmental enrichment (EE) included use of a running wheel and exposure to "novel objects...
Seeking A Safer Alternative To Lithium For Bipolar Disorder
Date: Apr-01-2013Toxicity problems and adverse side effects when taking lithium, the mainstay medication for treating bipolar disorder, are fostering a scientific hunt for insights into exactly how lithium works in the body - with an eye to developing a safer alternative. That's the topic of the cover story in the current edition of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society...
Hepatitis Safeguards Needed For HIV Sufferers
Date: Apr-01-2013Stronger protections are needed to prevent people with HIV from also becoming infected with hepatitis, researchers argue in a new study led by Michigan State University. Behaviors that put people at higher risk of contracting HIV - sharing needles, having unprotected sex or getting blood transfusions, for instance - also raise their risk of getting hepatitis B or C, diseases that attack the liver and, if untreated, can be deadly. The study, which included all registered cases of HIV in Michigan, found about four percent of HIV-positive people also had hepatitis...
Novel Intercellular Transportation System May Have Potential For Delivering RNAi And Other Gene-Based Therapeutics
Date: Apr-01-2013Important new research from UMass Medical School demonstrates how exosomes shuttle proteins from neurons to muscle cells where they take part in critical signaling mechanisms, an exciting discovery that means these tiny vehicles could one day be loaded with therapeutic agents, such as RNA interference (RNAi), and directly target disease-carrying cells. The study, published in the journal Neuron, is the first evidence that exosomes can transfer membrane proteins that play an important role in cell-to-cell signaling in the nervous system...
Body Dysmorphia And Self-Perceived Masculinity In Men
Date: Apr-01-2013Self perceived masculinity is higher in men with muscle dysmorphia, popularly called 'bigorexia', than other gym users, while male patients with anorexia nervosa had elevated association with feminine stereotypes, finds research in Biomed Central's open access journal Journal of Eating Disorders. ee Research over the last several decades has shown that increasingly men are admitting to being unhappy with their body image. This may show itself in either a desire to lose weight and become thinner, or to gain weight and become more muscular...
One Of The Earliest Possible Changes In The Development Of Prostate Cancer Detected By Scientists
Date: Apr-01-2013SCIENTISTS at the University of York have discovered the driving force behind the development of prostate cancer. Their research, published in Nature Communications and funded by the charity Yorkshire Cancer Research, reveals the existence of a cancer inducing DNA re-alignment in stem cells taken from human prostate cancers. This opens the way to the development of drugs that target the stem cells, leading to more effective therapies that work against the root cause of the disease...
Only One In Ten Smokers With Poor Mental Health Prescribed A Smoking Cessation Medication
Date: Apr-01-2013Although smoking prevalence has declined in the United Kingdom over recent decades, it has changed little among people with mental health disorders, remaining substantially higher than the national average. Yet a study published in the journal Addiction, presenting work carried out for a report released by the Royal College of Physicians and Royal College of Psychiatrists called 'Smoking and Mental Health', suggests that general practitioners (GPs) are missing opportunities to help smokers with mental health disorders to quit...
Concerns Raised About Ultrafine Particles From Improved Cookstoves
Date: Apr-01-2013A new study raises concerns about possible health impacts of very small particles of soot released from the "improved cookstoves" that international aid agencies are promoting to replace open-fire cooking in developing countries. It appears in the ACS journal Environmental Science & Technology. Brian Just and colleagues point out that 3 billion people worldwide still cook meals on stoves or open fires that burn wood, animal dung or other biomass fuel. These fires, which sometimes are indoors, release air pollutants linked to 3.5 million deaths annually...
