New Device Traps Particulates, Kills Airborne Pathogens
Date: Feb-04-2013A new device called a soft x-ray electrostatic precipitator protected immunocompromised mice from airborne pathogenic bacteria, viruses, ultrafine particles, and allergens, according to a paper published online ahead of print in the journal Applied and Environmental Microbiology. This device, known for short as a SXC ESP, is highly versatile, with multiple potential uses, and Washington University is working on licensing the technology. "Small particles are difficult to remove, and our device overcomes that barrier," says Pratim Biswas of Washington University, St. Louis...
Avoid Eight Cancer Screenings, Says Consumer Reports
Date: Feb-03-2013Consumer reports evaluated eleven cancer screening tests, and has found that most of us should avoid eight of them. The non-profit consumer's organization says that most preventive cancer screenings are oversold and may confuse rather than clarify. In a new report, the authors say that not all cancer screening tests are helpful. In fact, they added that some of them may be harmful. Consumer Reports emphasizes that its advice regarding avoiding eight cancer screenings is directed at those who are not at high risk and do not have signs and symptoms of cancer...
Once Punishment Is Removed, Rats, Like Humans, Return To Drinking
Date: Feb-03-2013Once heavy drinking impairs function, a variety of punishment-related threats may motivate people to stop drinking: spouses may threaten divorce, employers may threaten job loss, and courts threaten drunk drivers with losing their driver's license or incarceration. In the face of these threats, many alcohol abusers refrain from drinking, but relapse is very common when the threats of punishment fade, particularly when exposed to alcohol-associated environments. A new study by researchers at the National Institute on Drug Abuse suggests that rats may behave in the same way...
Damage To The Pelvic Floor During Vaginal Delivery
Date: Feb-03-2013Women are more likely to experience urinary incontinence, prolapse and faecal incontinence 20 years after one vaginal delivery rather than one caesarean section, finds new research published in a thesis from Sahlgrenska Academy, University of Gothenburg, Sweden. Urinary incontinence, prolapse and faecal incontinence are common conditions affecting adult women of all ages and can have a negative influence on quality of life...
Growing Evidence For The Lasting Impact Of Alcohol On The Brain
Date: Feb-03-2013Excessive alcohol use accounts for 4% of the global burden of disease, and binge drinking particularly is becoming an increasing health issue. A new review article published in Cortex highlights the significant changes in brain function and structure that can be caused by alcohol misuse in young people. Functional signs of brain damage from alcohol misuse in young people mainly include deficits in visual learning and memory as well as executive functions...
Vietnamese Mothers Whistle Away The Need For Diapers
Date: Feb-03-2013Western babies are potty trained later these days and need diapers until an average of three years of age. But even infants can be potty trained. A study by researchers at Sahlgrenska Academy, University of Gothenburg, Sweden, followed 47 infants and their mothers in Vietnam - where potty training starts at birth and the need for diapers is usually eliminated by nine months of age...
Metabolite Damage-Control: How Our Cells Cope With Toxic Small Molecules
Date: Feb-03-2013In this week's issue of the prestigious journal Nature Chemical Biology, scientists Carole Linster (University of Luxembourg), Emile Van Schaftingen (Louvain University), and Andrew D. Hanson (University of Florida, Gainesville) review an important, but so far neglected, part of metabolism, namely metabolite damage-control...
Link Between TV Viewing, Sedentary Lifestyle In Teens And Disease Risk In Adulthood
Date: Feb-03-2013A team of scientists at Umea University, in collaboration with colleagues in Melbourne, Australia, have found that television viewing and lack of exercise at age 16 is associated with the risk of developing metabolic syndrome at 43 years age. Metabolic syndrome is a name for the disorder of metabolism - a combination of abdominal obesity, elevated blood lipids, hypertension and impaired glucose tolerance - which provides for a significantly increased risk of developing type 2 diabetes, stroke and cardiovascular disease...
Findings Offer A Better Understanding Of The Development And Progression Of Multiple Sclerosis And Potential Future Therapeutic Target
Date: Feb-03-2013Researchers from Benaroya Research Institute at Virginia Mason (BRI) have found that proteins in the IL-6 signaling pathway may be leveraged as novel biomarkers of multiple sclerosis (MS) to gauge disease activity and as a target for new therapies. The research, which investigated how several components involved in immune response differ between MS patient and control samples, was conducted by a team of researchers at BRI led by Dr. Jane Buckner in collaboration with Dr. Mariko Kita at Virginia Mason Medical Center and was published in Science Translational Medicine...
More West Nile Virus In Orchards And Vineyards
Date: Feb-03-2013Washington State University researchers have linked orchards and vineyards with a greater prevalence of West Nile virus in mosquitoes and the insects' ability to spread the virus to birds, horses and people. The finding, reported in the latest issue of the journal PLOS ONE, is the most finely scaled look at the interplay between land use and with the virus's activity in key hosts...
