(Boston)--Changing the way doctors practice medicine is difficult, however a new study has shown that combining traditional education with quality improvement and incentives improves Human Papilloma virus (HPV) vaccination rates in boys and girls. The study, which appears on-line in the journal Vaccine, has the potential to produce sustained improvements in these vaccination rates. Every year, approximately three million Americans seek treatment for HPV related diseases. Twenty-seven thousand Americans develop HPV-related cancer while more than 5,000 people die from this ...

A special type of fat found in some people could be used to manage type 2 diabetes. Scientists from Monash University and Stockholm University have discovered that brown fat, nicknamed the 'good fat' because it warms up the body in cold temperatures, burning up calories in the process, also 'hoovers up' excess sugar. The findings, published in The Journal of Cell Biology, are significant for people with type 2 diabetes, whose bodies are unable to respond to insulin properly, resulting in elevated blood glucose levels. Researchers believe that if brown fat cells can ...

Beer-Sheva, Israel, Nov. 24, 2014 - A new, enhanced MRI diagnostic approach was, for the first time, able to identify significant damage to the blood-brain barrier (BBB) of professional football players following "unreported" trauma or mild concussions. Published in the current issue of JAMA Neurology, this study could improve decision making on when an athlete should "return to play." According to Dr. Alon Friedman, from the Ben-Gurion University Brain Imaging Research Center and discoverer of the new diagnostic, "until now, there wasn't a diagnostic capability to identify ...

"Memetics," or the study of memes, is a very popular discipline among cultural researchers now, particularly as it concerns new media like viral videos. But no one seems to know what a meme really is. Originally coined by evolutionary biologist Richard Dawkins, the "meme" transfers cultural information much the way that genes inherit biological properties. Pharrell Williams' feel-good hit "Happy" (2013), one of the top-selling singles of all time, is a recent example of a wildly popular meme. Originally tucked away in the soundtrack of the film Despicable Me 2, the song ...

WASHINGTON - Teens prescribed anti-anxiety or sleep medications may be up to 12 times more likely to abuse those drugs illegally than teens who have never received a prescription, often by obtaining additional pills from friends or family members, according to new research published by the American Psychological Association. Based on surveys of more than 2,700 high school and middle school students from the Detroit area, almost 9 percent had been prescribed a potentially addictive benzodiazepine anti-anxiety medication (e.g., Xanax, Valium or Klonopin) or sleep medication ...

COLUMBUS, Ohio - When researchers wanted to verify alcohol-use survey results at a senior housing center, they came up with a novel way to measure residents' drinking: Count the empty bottles in recycling bins. Scientists compared the recycling bin results with two residential surveys gauging drinking habits of people living in a San Diego complex for low-income, older adults. "We were able to check how much the residents said they were drinking with the empty beer, wine and liquor containers they were actually putting in the recycling bins," said John Clapp, co-author ...

When it comes to teaching dogs how to sniff out explosives, there's nothing quite like the real thing to make sure they're trained right. That's the message from William Kranz, Nicholas Strange and John Goodpaster of Indiana University-Purdue University Indianapolis (IUPUI) in the US, after finding that dogs that are trained with so-called "pseudo-explosives" could not reliably sniff out real explosives (and vice versa). Their findings are published online in Springer's journal Analytical and Bioanalytical Chemistry. Genuine explosive materials are traditionally used ...

Washington, DC (November 26, 2014) - The holiday season gives people the opportunity to reconnect with friends and family each year. Sometimes these interactions can be stressful, especially around the Thanksgiving table where a heated debate can occur. How come some people are better at handling these stressful interactions than others? A recent study published in the journal Human Communication Research by researchers at Rollins College and The Pennsylvania State University found that individuals who were exposed to intense verbal aggression as children are able to handle ...

New Rochelle, NY, November 24, 2014--Genetically engineered pigs, minipigs, and microminipigs are valuable tools for biomedical research, as their lifespan, anatomy, physiology, genetic make-up, and disease mechanisms are more similar to humans than the rodent models typically used in drug discovery research. A Comprehensive Review article entitled "Current Progress of Genetically Engineered Pig Models for Biomedical Research," describing advances in techniques to create and use pig models and their impact on the development of novel drugs and cell and gene therapies, is ...

DENVER--Nov. 24, 2014-- Four years ago, a bulldozer operator turned over some bones during construction at Ziegler Reservoir near Snowmass Village, Colorado. Scientists from the Denver Museum of Nature & Science were called to the scene and confirmed the bones were those of a juvenile Columbian mammoth, setting off a frenzy of excavation, scientific analysis, and international media attention. This dramatic and unexpected discovery culminates this month with the publication of the Snowmastodon Project Science Volume in the international journal Quaternary Research. Fourteen ...

Conventional treatment seeks to eradicate cancer cells by drugs and therapy delivered from outside the cell, which may also affect (and potentially harm) nearby normal cells. In contrast to conventional cancer therapy, a University of Cincinnati team has developed several novel designs for iron-oxide based nanoparticles that detect, diagnose and destroy cancer cells using photo-thermal therapy (PTT). PTT uses the nanoparticles to focus light-induced heat energy only within the tumor, harming no adjacent normal cells. The results of the UC work will be presented at the ...

Scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have learned new details about how an important tumor-suppressing protein, called p53, binds to the human genome. As with many things in life, they found that context makes a big difference. The researchers mapped the places where p53 binds to the genome in a human cancer cell line. They compared this map to a previously obtained map of p53 binding sites in a normal human cell line. These binding patterns indicate how the protein mobilizes a network of genes that quell tumor ...

Researchers at UC San Francisco have identified patterns of genetic activity that can be used to diagnose endometriosis and its severity, a finding that may offer millions of women an alternative to surgery through a simple noninvasive procedure. The study is online in the journal Endocrinology. "This promising molecular diagnostic approach would not have been possible without advances in genomics and bioinformatics," said senior author Linda Giudice, MD, PhD, distinguished professor and chair of obstetrics, gynecology and reproductive sciences at UCSF. "Importantly, ...

A protein that stimulates the brain to awaken from sleep may be a target for preventing Alzheimer's disease, a study by researchers at Washington University School of Medicine in St. Louis suggests. In recent years, scientists at Washington University have established links between sleep problems and Alzheimer's. For example, they have shown in people and in mice that sleep loss contributes to the growth of brain plaques characteristic of Alzheimer's, and increases the risk of dementia. The new research, in mice, demonstrates that eliminating that protein - called orexin ...

How does glass transition from a liquid to its familiar solid state? How does this common material transport heat and sound? And what microscopic changes occur when a glass gains rigidity as it cools? A team of researchers at NYU's Center for Soft Matter Research offers a theoretical explanation for these processes in Proceedings of the National Academy of Sciences. Our understanding of glasses as they change state is relatively limited. This is because, unlike other materials such as metals, their constituent particles--which can be as small as a billionth of a meter ...

People who see their group as more homogenous - for instance, the more one thinks Americans are similar to each other - are less likely to be influenced by external terrorist threat alerts, according to research from NYU's Steinhardt School of Culture, Education, and Human Development. "Among people who viewed their group to be homogeneous, external threat did not translate to higher perceived threat, and they did not influence beliefs about the legitimacy of the U.S. military intervention in Iraq," said study author Rezarta Bilali, assistant professor of psychology and ...

ANN ARBOR--The medical community may be inadvertently creating a new generation of illegal, recreational drug users by prescribing anti-anxiety or sleep medications to teenagers, say University of Michigan researchers. Teens prescribed anxiety or sleep medications are up to 12 times more likely to abuse those drugs than those who had never had a prescription, either by using someone else's prescription pills or to get high or experiment, according to a study from the U-M School of Nursing. Nearly 9 percent of the 2,745 adolescent study participants had received ...

A team of scientists from Arizona State University's Biodesign Institute and IBM's T.J. Watson Research Center have developed a prototype DNA reader that could make whole genome profiling an everyday practice in medicine. "Our goal is to put cheap, simple and powerful DNA and protein diagnostic devices into every single doctor's office," said Stuart Lindsay, an ASU physics professor and director of Biodesign's Center for Single Molecule Biophysics. Such technology could help usher in the age of personalized medicine, where information from an individual's complete DNA ...

SAN FRANCISCO (November 24, 2014) --A team of scientists, including researchers from the California Academy of Sciences, has reconstructed a detailed "tree of life" for turtles. The specifics of how turtles are related--to one another, to other reptiles, and even to dinosaurs--have been hotly debated for decades. Next generation sequencing technologies in Academy labs have generated unprecedented amounts of genetic information for a thrilling new look at turtles' evolutionary history. These high-tech lab methods revolutionize the way scientists explore species origins and ...

Members of the public in sub-Saharan Africa who are carriers of the hereditary disease sickle cell disease must be educated aggressively through public health campaigns to raise awareness of the risks of parenting offspring with the disease if their partner is also a carrier, according to research published in the International Journal of Medical Engineering and Informatics. There are many physical and emotional public health components of sickle cell disease, explains William Ebomoyi of the Department of Health Studies College of Health Sciences, Chicago State University, ...

WOODS HOLE, Mass.--David Johnson was standing in a salt marsh on the northern Massachusetts coast when he saw a fiddler crab, Uca pugnax, nearly 50 miles north of its supposed natural range. The migration north of this charismatic crab with the big, waving claw may be yet another sign of climate change. Johnson, then a scientist at the Marine Biological Laboratory (MBL) Ecosystems Center, has published his observations in the Journal of Crustacean Biology. The fiddler crab is an attention-getting crustacean; the males have an oversized claw that they use to attract a ...

Over a million US military veterans lacked healthcare coverage in 2012, according to new estimates published in The Lancet. While many people believe that all veterans are covered by the Veterans Affairs health care system, less than half (8.9 million) of the 22 million veterans in the US are covered by VA health benefits, and most veterans are covered by private health insurance. Uninsured veterans are more likely to be young, single, African American, and veterans of Iraq and Afghanistan. However, the authors of this viewpoint estimate that universal health coverage ...
