Survivors of childhood cancers are at an increased risk of another battle with cancer later in life, according to new research published online June 4 by the Annals of Internal Medicine. In the largest study to date of risk for gastrointestinal (GI) cancers among people first diagnosed with cancer before the age of 21, researchers found that childhood cancer survivors develop these malignancies at a rate nearly five times that of the general population. While there was some preliminary evidence that childhood cancer survivors develop GI cancers more often and at an earlier ...

SCAI's Women in Innovations (WIN) and Abbott's Women's Heart Health Initiative have created an OB/GYN screening program to help educate and prevent cardiovascular disease in women by bringing screenings tools and information to the gynecologist's office, according to a news article by The Wall Street Journal. The program discovered that one in nearly eight women has three or more cardiac risk factors, but do not know it, according to a study presented at the SCAI 2012 Scientific Sessions. OBGYN specialist Daniel P. McDonald, MD, and OBGYN specialist Marc A. Wilson, MD, ...

Philadelphia, PA, June 4, 2012 – Posttraumatic stress disorder (PTSD) is among the most common, distressing, and disabling medical consequences of combat or other extremely stressful life events. The first-line treatment for PTSD is exposure therapy, a type of behavioral therapy where patients confront their fears in a safe environment. Although it is an effective treatment, many patients still experience symptoms after treatment and there is a relatively high drop-out rate. In an effort to improve existing treatments, a new study appearing in Biological Psychiatry this ...

For millions of Facebook users, choosing which photo to use for an online profile is an important decision. Should it be lighthearted or professional, personal or more abstract? According to a study by researchers at the UT Dallas Center for Vital Longevity and the University of Illinois Urbana-Champaign, the photos we select may reflect individual preferences, but they also appear to reflect more deeply rooted, unconscious cultural differences. Previous research has shown that culture can affect not only language and custom, but also how we experience the world and process ...

CAMBRIDGE, Mass. -- Police and security teams guarding airports, docks and border crossings from terrorist attack or illegal entry need to know immediately when someone enters a prohibited area, and who they are. A network of surveillance cameras is typically used to monitor these at-risk locations 24 hours a day, but these can generate too many images for human eyes to analyze. Now, a system being developed by Christopher Amato, a postdoc at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), can perform this analysis more accurately and in a fraction ...

Astronomers have found strong evidence that a massive black hole is being ejected from its host galaxy at a speed of several million miles per hour. New observations from NASA's Chandra X-ray Observatory suggest that the black hole collided and merged with another black hole and received a powerful recoil kick from gravitational wave radiation. "It's hard to believe that a supermassive black hole weighing millions of times the mass of the sun could be moved at all, let alone kicked out of a galaxy at enormous speed," said Francesca Civano of the Harvard-Smithsonian Center ...

Tampa, FL (June 4, 2012) Those cups of coffee that you drink every day to keep alert appear to have an extra perk – especially if you're an older adult. A recent study monitoring the memory and thinking processes of people older than 65 found that all those with higher blood caffeine levels avoided the onset of Alzheimer's disease in the two-to-four years of study follow-up. Moreover, coffee appeared to be the major or only source of caffeine for these individuals. Researchers from the University of South Florida (www.usf.edu) and the University of Miami (www.miami.edu)say ...

St. Louis, MO, June 4, 2012 – The dental profession needs to build a stronger connection between oral health and general health—not only for individual patients, but also at the community level, according to the special June issue of The Journal of Evidence-Based Dental Practice (JEBDP), the foremost publication of information about evidence-based dental practice, published by Elsevier. The special issue follows the usual format of JEBDP, comprising expert reviews and analyses of the scientific evidence on specific dental procedures. "Yet the coverage goes beyond a review ...

(Boston) - Boston University School of Medicine (BUSM) researchers recently uncovered a brain signaling pathway responsible for regulating the renal excretion of sodium. The findings appear in the Journal of the Federation of American Societies for Experimental Biology. Hypertension, or chronic high blood pressure, affects one-third of adults, significantly increasing cardiovascular risk and mortality. Approximately 50 percent of hypertensive patients are salt-sensitive and exhibit an increase in blood pressure following salt-intake. According to the researchers, little ...

BOSTON – An antibody that helps a person's own immune system battle cancer cells shows increasing promise in reducing tumors in patients with advanced kidney cancer, according to researchers at Beth Israel Deaconess Medical Center. The results of an expanded Phase 1 trial presented at the American Society of Clinical Oncology's annual conference in Chicago, showed that some patients treated with a fully human monoclonal antibody developed by Bristol Myers Squibb had a positive response to the effort by the agent, BMS-936558, to prolong the immune system's efforts to fight ...

Menlo Park, Calif. — Scientists studying neutrinos have found with the highest degree of sensitivity yet that these mysterious particles behave like other elementary particles at the quantum level. The results shed light on the mass and other properties of the neutrino and prove the effectiveness of a new instrument that will yield even greater discoveries in this area. The Enriched Xenon Observatory 200 (EXO-200), an international collaboration led by Stanford University and the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory, has begun one of ...

New University of Cincinnati research has found that fewer parents in the United States vaccinated their children in the wake of concerns about a purported link (now widely discredited) between the MMR (measles, mumps, rubella) vaccine and autism. Lenisa Chang, assistant professor of economics in UC's Carl H. Lindner College of Business, found that the MMR-autism controversy, which played out prominently in the popular media following publication in a 1998 medical journal, led to a decline of about two percentage points in terms of parents obtaining the MMR vaccine for ...

PASADENA, Calif.—In the biggest result of its kind in more than ten years, physicists have made the most sensitive measurements yet in a decades-long hunt for a hypothetical and rare process involving the radioactive decay of atomic nuclei. If discovered, the researchers say, this process could have profound implications for how scientists understand the fundamental laws of physics and help solve some of the universe's biggest mysteries—including why there is more matter than antimatter and, therefore, why regular matter like planets, stars, and humans exists at all. ...

Physicians can reduce the number of heart failure deaths and unnecessary hospital admissions by using a new computer-based algorithm developed at the Institute for Clinical Evaluative Sciences (ICES) that calculates each patient's individual risk of death. Published in the Annals of Internal Medicine, the algorithm improves upon clinical decision-making and determines whether or not a patient with heart failure should be admitted to hospital. To bring this tool into the emergency departments, Peter Munk Cardiac Centre cardiologists are developing smartphone and web-based ...

MATERIALS – Transparent performance . . . Windshields, windows, solar panels, eyeglasses, heart stents and hundreds of other products representing a multi-billion-dollar market are potential targets for Oak Ridge National Laboratory's thin-film superhydrophobic technology. Conventional commercially available products tend to lack transparency, suitable bonding capability or both, making them largely impractical, said Tolga Aytug, one of the developers. The ORNL product, based on glass, can be produced with manufacturing processes that are cost effective and easily scaled ...

DURHAM, N.C. -- Treating adolescents for major depression can also reduce their chances of abusing drugs later on, a secondary benefit found in a five-year study of nearly 200 youths at 11 sites across the United States. Only 10 percent of 192 adolescents whose depression receded after 12 weeks of treatment later abused drugs, compared to 25 percent of those for whom treatment did not work, according to research led by John Curry, a professor of psychology and neuroscience at Duke University. "It turned out that whatever they responded to -- cognitive behavioral therapy, ...

Reston, Va. (June 4, 2012) – For those with esophageal cancer, initial staging of the disease is of particular importance as it determines whether to opt for a curative treatment or palliative treatment. Research presented in the June issue of The Journal of Nuclear Medicine shows that physicians using positron emission tomography (PET)/computed tomography (CT) can discern incremental staging information about the cancer, which can significantly impact management plans. In 2012, an estimated 17,500 people will be diagnosed with esophageal cancer and 15,000 will die from ...

Researchers at the University of Toronto Scarborough (UTSC) used an innovative technique to examine chemical interactions that are implicated in Parkinson's Disease. The work details how a protein called alpha-synuclein interacting with the brain chemical dopamine can lead to protein misfolding and neuronal death. Parkinson's Disease is a neurodegenerative disease which results in loss of motor control and cognitive function. Although the cause isn't known precisely, the disease involves the death of brain cells that produce dopamine, a chemical important in neuronal ...

Tampa, Fla. (June 4, 2012) – After carrying out a study comparing the repopulation efficiency of immature hepatic stem/progenitor cells and mature hepatocytes transplanted into liver-injured rats, a research team from Sapporo, Japan concluded that mature hepatocytes offered better repopulation efficiency than stem/progenitor cells. Until day 14 post-transplantation, the growth of the stem/progenitor cells was faster than the mature hepatocytes, but after two weeks most of the stem/progenitor cells had died. However, the mature hepatocytes continued to survive and proliferate ...

Tampa, Fla. (June 4, 2012) – When autologous (self-donated) lung-derived mensenchymal stem cells (LMSCs) were transplanted endoscopically into 13 adult female sheep modeled with emphysema, post-transplant evaluation showed evidence of tissue regeneration with increased blood perfusion and extra cellular matrix content. Researchers concluded that their approach could represent a practical alternative to conventional stem cell-based therapy for treating emphysema. The study is published in Cell Transplantation (21:1), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/. ...

The mosquito is possibly summer's biggest nuisance. Sprays, pesticides, citronella candles, bug zappers — nothing seems to totally deter the blood-sucking insect. And neither can rain apparently. Even though a single raindrop can weigh 50 times more than a mosquito, the insect is still able to fly through a downpour. Georgia Tech researchers used high-speed videography to determine how this is possible. They found the mosquito's strong exoskeleton and low mass render it impervious to falling raindrops. The research team, led by Assistant Professor of Mechanical Engineering ...

WEST LAFAYETTE, Ind. - A new Purdue University-developed process for creating biofuels has shown potential to be cost-effective for production scale, opening the door for moving beyond the laboratory setting. A Purdue economic analysis shows that the cost of the thermo-chemical H2Bioil method is competitive when crude oil is about $100 per barrel when using certain energy methods to create hydrogen needed for the process. If a federal carbon tax were implemented, the biofuel would become even more economical. H2Bioil is created when biomass, such as switchgrass or corn ...

As voters increasingly rely on websites of presidential primary candidates for news, they run a risk because candidates' online attacks are not vetted through traditional "watchdog journalists" and other gatekeepers to determine accuracy or fairness, according to a study by Baylor University researchers. "The primary danger is that constituents often use this one-sided information to decide how to vote," said Mia Moody, Ph.D., study co-author and an assistant professor of journalism, public relations and new media in Baylor's College of Arts & Sciences. The study — "Not ...

Click here for more information. Drugs for type 2 diabetes can contribute to weight gain, bone fractures and cardiovascular problems, but in mice, an investigational drug appears to improve insulin sensitivity without those troublesome side effects, researchers at Washington University ...

Over the weekend of June 2 and 3, Typhoon Mawar skirted the east coast of the Philippines bringing heavy surf, heavy rainfall and gusty winds that led to several missing and injured people. NASA's TRMM satellite and Aqua satellite showed heavy rainfall and cloud extent of the storm. On June 1, Mawar (known as Ambo in the Philippines) had maximum sustained winds near 45 knots and it was about 245 miles east-northeast of Manila, Philippines. On that day, as Mawar continued north, some warnings were posted for the Philippines: Public storm warning signal #1 was up in the ...
