| CDC urging men at risk of Zika to postpone fatherhood Posted: 30 Sep 2016 12:19 PM PDT CDC today announced updates to its interim guidance for pre-pregnancy counseling and prevention of sexual transmission of Zika based on ongoing assessment of available data, primarily extending the timeframe for men with possible Zika exposure but no Zika symptoms to wait before attempting pregnancy with their partner and extending the time for use of condoms by these men to protect against sexual transmission of Zika virus infection. |
| Formaldehyde damages proteins, not just DNA Posted: 30 Sep 2016 11:43 AM PDT Formaldehyde, a common toxicant and carcinogen recently subjected to new federal regulations, may be more dangerous than previously thought, a new study suggests. |
| Details of mysterious Utah Zika-related death: Transmission by tears or sweat Posted: 30 Sep 2016 11:30 AM PDT The first Zika virus-related death in the continental U.S. occurred in June of this year, but even now, months later, two aspects of this case continue to puzzle health experts. First, why did this patient die? It is quite rare for a Zika infection to cause severe illness in adults, much less death. Second, how did another individual, who visited the first while in the hospital, become ill from Zika? This second patient did not do anything that was known at the time to put people at risk for contracting the virus. |
| Posted: 30 Sep 2016 10:05 AM PDT When exposed to cold, clusters of cells within the body's white fat become beige -- a color change that reflects the creation of more energy-producing mitochondria, cellular components that enable cells to burn calories and give off heat. But since white fat cells have very few nerves, how do beige fat cells get the message that it's cold outside? |
| Noncoding mutations disrupt cooperative function of 'gene families' in rare genetic disorder Posted: 30 Sep 2016 09:04 AM PDT Scientists say they are one step closer to understanding the genetic mechanism of a rare, complex, multiple-gene disorder called Hirschsprung's disease. Their results suggest that many patients develop the disease when multiple mutations in gene regulatory sequences of a specific gene combine to destroy the normal cooperative function of a whole network of genes. |
| Registry data used to examine oral anticoagulant therapy, appropriate use Posted: 30 Sep 2016 09:02 AM PDT The American College of Cardiology's National Cardiovascular Data Registry was the source of data for research published throughout 2016, including a study examining if atrial fibrillation patients are being prescribed oral anticoagulants, how appropriate use criteria correlates to angioplasty rates and the variation among racial groups for revascularization procedures. |
| Posted: 30 Sep 2016 09:02 AM PDT Eutrophication and brownification change phytoplankton community structure and decrease the production of essential omega-3 fatty acids in lakes. Perch growing in oligotrophic clear-water lakes contain 1.5-1.9 times more essential omega-3 fatty acids than those grown in eutrophic and brown-water lakes. |
| Advancing non-animal testing methods: First set of novel knowledge tools published Posted: 30 Sep 2016 09:02 AM PDT An adverse outcome pathway, or AOP, is a highly structured way of describing a toxicological process which can lead to an adverse health effect in humans or wildlife, caused by an unsafe exposure to a chemical substance. The first five adverse outcome pathways have now been published by experts. The AOPs are novel knowledge management tools in toxicology and are useful for supporting risk assessment to human health. They are also valuable for helping to avoid animal testing through the use of alternative methods. |
| Heavy hitters: Obesity rate soars among professional baseball players Posted: 30 Sep 2016 05:59 AM PDT Major League Baseball players have become overwhelmingly overweight and obese during the last quarter century, say health researchers. They found that the athletes' weight held steady for over 100 years, with the majority of them weighing in at what is considered "normal," -- i.e., with a body mass index (BMI) between 18.5 and 24.9. However, around 1991 the average player's BMI began to rise, and over the last 25 years nearly 80 percent of players fall into the overweight or obese category with a BMI above 25. |
| Universal flu vaccine designed by scientists Posted: 30 Sep 2016 05:58 AM PDT Scientists have designed a new generation of universal flu vaccines to protect against future global pandemics that could kill millions. Researchers researchers have devised two universal vaccines; a USA-specific vaccine with coverage of 95% of known US influenza strains; and a universal vaccine with coverage of 88% of known flu strains globally. |
| With worrisome animal research, more focus needed on effects of cannabis on human development Posted: 30 Sep 2016 05:08 AM PDT In this new era of legalized marijuana, far too little research has been conducted on the effect of cannabis on the development of human embryos, say researchers who scoured medical literature on the topic and found what they say is worrisome animal research. |
| Caffeine-based compounds show promise against Parkinson's disease Posted: 30 Sep 2016 05:08 AM PDT Two caffeine-based chemical compounds have been developed that show promise in preventing the ravages of Parkinson's disease. Parkinson's disease attacks the nervous system, causing uncontrolled shakes, muscle stiffness, and slow, imprecise movement, chiefly in middle-aged and elderly people. It is caused by the loss of brain cells (neurons) that produce dopamine, an essential neurotransmitter that allows neurons to "talk" to each other. |
| 'Advances and Refinements' in Neuromodulators for Facial Rejuvenation Posted: 29 Sep 2016 12:20 PM PDT Plastic surgeons have a range of effective products and minimally invasive techniques for patients seeking to reverse the signs of facial aging. A review and update on facial rejuvenation using botulinum toxin "neuromodulators" has now been completed. |
| Setting the stage from diagnoses to dimensions Posted: 29 Sep 2016 06:28 AM PDT The case-control method, where researchers compare patients with a particular disease to healthy control participants, has increased understanding of disease-related effects at a group level. However, psychiatric pathology complicates assumptions of the method – that the illness can be defined and that patients cleanly fit the definition. Although psychiatry has characterized different diagnoses, patients within a diagnosis vary widely and symptoms often overlap diagnostic labels. |
| New way to define proarrhythmic risk? Posted: 29 Sep 2016 06:28 AM PDT There generally are two approaches used to indirectly assess proarrhythmic risk, but some researchers believe that human induced pluripotent stem-cell derived (hiPSC)-cardiomyocytes offer an opportunity to change the paradigm. |
| Treating malaria by stabilizing leaky blood vessels Posted: 29 Sep 2016 06:28 AM PDT Boosting a protective protein to stabilize blood vessels that are weakened by malaria showed improved survival, beyond that of antimalarial drugs alone in pre-clinical research. Researchers now describe how their approach bolsters the body's own capabilities to protect itself against cerebral malaria, rather than solely targeting the malaria parasites in the blood. |
| Older adults no slower than young adults at taking control of semi-autonomous vehicles Posted: 29 Sep 2016 06:28 AM PDT Older adults have comparable response times to young adults when tasked with taking control of a semi-autonomous vehicle, new research shows. |
| Administering additional antibiotic prior to c-section reduces infection rates by 50 percent Posted: 28 Sep 2016 07:06 PM PDT A change of practice in C-section delivery -- administering antibiotics before c-section -- improves the health of mom and baby, new research concludes. |
| Posted: 28 Sep 2016 06:27 PM PDT In order to optimally utilize fungi, and to fight them when necessary, we require greater insight into the functions that they can perform. Researchers have exposed a new layer of functional complexity in fungi. |
| Minimalist shoes increase leg and foot muscles, study shows Posted: 28 Sep 2016 01:07 PM PDT Running in minimalist shoes can increase leg and foot muscle volume, indicating its potential application in rehabilitation program, say researchers in a new report. |
| Exercise not shown to reduce women's risk of developing MS Posted: 28 Sep 2016 01:07 PM PDT A large, new study shows no evidence that exercise may reduce a woman's risk of developing multiple sclerosis (MS). Previous small studies had shown conflicting results. |
| Now is the lightest you will weigh all year Posted: 28 Sep 2016 12:41 PM PDT As swimsuit season wanes and the holiday season edges closer, Americans everywhere should take a moment to enjoy the current state of their waistline. For the average person, the time just before the start of the holiday season is the low point in an annual weight gain pattern that peaks during the holidays and takes nearly half a year to fully shed. |
| New imaging method developed for lipid with many functions Posted: 28 Sep 2016 12:39 PM PDT An essential molecule in cells, called phosphatidic acid (PA), is at the center of a cellular biology mystery. This lipid, or fatty molecule, is a jack-of-all-trades -- based on context, it can cause cells to move, divide or commit suicide. Elevated levels of PA have also been observed in many types of cancer as well as autoimmune and neurodegenerative diseases. But the lipid has been hard to study, because there have been no good tools for imaging where it gets produced -- until now. |
| Posted: 28 Sep 2016 12:37 PM PDT Comprehensive occupational therapy care requires a family-centered approach including treatment for the person with dementia and education for the caregiver. Clinical assessments exist to evaluate the capabilities of a person with dementia, but until now, occupational therapists did not have a validated instrument to gain understanding of the caregiver's perceptions of the person with dementia's abilities. |
| Nighttime hot flashes may spark mild depression Posted: 28 Sep 2016 12:37 PM PDT A woman's perception that she is experiencing a high number of nighttime hot flashes can trigger mild symptoms of depression during menopause, according to a new study. |
| Posted: 28 Sep 2016 12:35 PM PDT Overpumping of groundwater to supply one of the planet's largest cities could be jeopardizing the future water supply for citizens living outside the city center, say researchers working in Dhaka, Bangladesh. With a population of over 15 million people, Dhaka is considered a mega-city and shares many of the water management problems common to other major cities. |
