The first research to actively analyze adult male sea turtles (Caretta caretta) using satellite tracking to link geography with pollutants has revealed the potential risks posed to this threatened species by manmade chemicals. The research, published today in Environmental Toxicology and Chemistry, examines the different levels of chemicals in the blood of both migratory and residential turtles. "The risks posed by persistent organic pollutants (POPs) remain largely a mystery for threatened loggerhead sea turtles," said lead author Jared Ragland from the College of Charleston, ...

PROVIDENCE, R.I. [Brown University] — Researchers at Brown University have found that specific genetic variations can predict how persistently people will believe advice they are given, even when it is contradicted by experience. The story they tell in a paper in the April 20 issue of the Journal of Neuroscience is one of the byplay between two brain regions that have different takes on how incoming information should influence thinking. The prefrontal cortex (PFC), the executive area of the brain, considers and stores incoming instructions such as the advice of other ...

After the acute treatment window closes, the only effective treatment for stroke is physical/occupational therapy. Now scientists from Children's Hospital Boston report a two-pronged molecular therapy that leads to significant recovery of skilled motor function in a rat model of stroke. Their findings are reported April 20 in the Journal of Neuroscience. By combining two molecular therapies—each known to promote some recovery on its own—the researchers achieved more nerve growth and a greater recovery of motor function than with either treatment alone. One therapy, inosine, ...

DALLAS – April 19, 2011 – Curbing carbohydrates is more effective than cutting calories for individuals who want to quickly reduce the amount of fat in their liver, report UT Southwestern Medical Center researchers. "What this study tells us is that if your doctor says that you need to reduce the amount of fat in your liver, you can do something within a month," said Dr. Jeffrey Browning, assistant professor of internal medicine at UT Southwestern and the study's lead author. The results, available online and in an upcoming issue of the American Journal of Clinical ...

A potential vaccine against bacteria that cause serious gastric disorders including stomach cancer may be a step closer following a pioneering study by a University of Guelph chemist. In the first published study of its kind, a team led by Prof. Mario Monteiro, Department of Chemistry, found a carbohydrate-based antigen caused mice to develop antibodies against a common bacterium linked to gastric cancer. "This is the first jab at a sugar-based vaccine against Helicobacter pylori," said Monteiro, who completed the study with former undergrad student Stacey Britton. Their ...

LOS ANGELES—(April 19, 2011)—Stepping outside to smoke a cigarette may not be enough to protect the lungs and life of a pregnant woman's unborn child, according to a new study in the American Journal of Physiology. The study, by researchers at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed), found prenatal exposure to toxic components of a newly recognized category of tobacco smoke—known as "thirdhand smoke"—can have as serious or an even more negative impact on an infants' lung development as postnatal or childhood exposure to ...

University of Adelaide researchers have shown for the first time how peppermint helps to relieve Irritable Bowel Syndrome, which affects up to 20% of the population. In a paper published this week in the international journal Pain, researchers from the University's Nerve-Gut Research Laboratory explain how peppermint activates an "anti-pain" channel in the colon, soothing inflammatory pain in the gastrointestinal tract. Dr Stuart Brierley says while peppermint has been commonly prescribed by naturopaths for many years, there has been no clinical evidence until now to ...

It is not that adolescent students should stop using the television or Internet, but that they should learn how to use them. This is one of the premises of the UNESCO Cathedra in Communication and Educational Values, based at the Faculty of Philosophy and Educational Sciences of the University of the Basque Country (UPV/EHU). A premise that responds to the results arising from the research since the Cathedra began in December 2009. "Our objective is the communication media —mainly new technologies and television— as agents of socialisation. We are convinced that, in the ...

"Information alone is not good enough", Dr Karina Weichold of the Jena University (Germany) knows. Because even children know that alcohol consumption and smoking can cause health damage. "Therefore prevention needs to start somewhere else." This is what the developmental scientists, together with colleagues from the Institute of Psychology and the Center for Applied Developmental Science of the Jena University, are trying to achieve with their specially developed prevention programme IPSY. In a new study based on about 1700 school children, aged between 10 and 15 years ...

April 19, 2011 – (BRONX, NY) – The brain's hypothalamus plays a key role in obesity and one of its major complications – type 2 diabetes. Nerve cells in the hypothalamus detect nutrients and hormones circulating in the blood and then coordinate a complex series of behavioral and physiological responses to maintain a balance between calories eaten and calories burned. Obesity and diabetes can result when this regulatory mechanism goes awry. Now, research by postdoctoral fellow Clémence Blouet, Ph.D., and Gary Schwartz, Ph.D., professor in the Dominick P. Purpura Department ...

New research published on bmj.com today adds to mounting evidence that calcium supplements increase the risk of cardiovascular events, particularly heart attacks, in older women. The findings suggest that their use in managing osteoporosis should be re-assessed. Calcium supplements are often prescribed to older (postmenopausal) women to maintain bone health. Sometimes they are combined with vitamin D, but it's still unclear whether taking calcium supplements, with or without vitamin D, can affect the heart. The Women's Health Initiative (WHI) study - a seven-year ...

Experts today challenge the view that popular drugs to prevent disease - like statins and antihypertensives to prevent heart disease and stroke, or bisphosphonates to prevent fractures – represent value for money. In a paper published on bmj.com today, Teppo Järvinen and colleagues argue that the benefits seen when these drugs are tested in clinical trials may not apply in the real world. They argue that value for money in real life clinical practice is likely to be much lower than in a clinical trial, where patients are carefully selected and receive special attention ...

A major culture shift is needed to address the problems of long term sickness absence in the police service, says an expert on bmj.com today. Dr Derek Summerfield reviewed 300 cases of officers retiring on mental health grounds during his time as consultant occupational psychiatrist to the Metropolitan Police Service from 2001 to 2004. During this time, 4.8% of the workforce was not doing full operational duties - a loss of the equivalent of 180 police officers monthly - because of stress related absence. Furthermore, retirement on mental health grounds as a proportion ...

DURHAM, N.H. – Most Americans now agree that climate change is occurring, but still disagree on why, with opinions about the cause of climate change defined by political party, not scientific understanding, according to new research from the Carsey Institute at the University of New Hampshire. Republicans most often point to natural causes of climate change while Democrats most often believe that human activities are the cause. The greatest polarization occurs among people who believe they have the best understanding. "Although there remains active discussion among ...

A large group of distinguished scientists published a very detailed and rather complex paper describing the association between alcohol consumption and cancer in the BMJ. It is based on data from the EPIC study in Europe, with a mean follow up of 8.8 years for more than 300,000 subjects. The authors describe an increase in risk of many cancers from alcohol intake, but do not give data permitting the detection of a threshold of intake for an adverse effect on cancer risk. The investigators conclude that "In western Europe, an important proportion of cases of cancer can ...
