Oncolytic viruses quickly infect and kill cancer stem cells, which may provide a treatment for tumors that are resistant to conventional chemotherapy and radiation, particularly pancreatic cancer, according to new research from Memorial Sloan-Kettering Cancer Center in New York. The findings are especially important since pancreatic cancer has a poor prognosis and is difficult to detect and treat at early stages. Investigators led by Joyce Wong, MD, surgical researcher with Memorial Sloan-Kettering Cancer Center, investigated whether they could use oncolytic viruses, ...

DALLAS – May 9, 2011 – Researchers at UT Southwestern Medical Center have uncovered new clues about how the intestine maintains friendly relations with the 100 trillion symbiotic bacteria that normally live in the digestive tract. Their latest findings, available online today and in a future edition of the Proceedings of the National Academy of Sciences, suggest that a once enigmatic cell population which lurks in the intestinal lining is essential for preventing friendly bacteria from invading into deeper tissue where they can cause debilitating conditions like inflammatory ...

When doctors give heart drugs to patients, the time of day can make a big difference, according to new research by University of Guelph scientists. Many doctors prefer to give heart drugs to patients in the morning. But the study revealed that angiotensin-converting enzyme (ACE) inhibitors – commonly given to patients with high blood pressure or after a heart attack or during heart failure – improve heart structure and function when given at sleep time. In fact, when administered during wake time, ACE inhibitors are no more effective than a placebo, the study found. The ...

New York, N.Y. (May 9, 2011) – In the first comprehensive study of autism prevalence using a total population sample, an international team of investigators from the U.S., South Korea, and Canada estimated the prevalence of autism spectrum disorders (ASD) in South Korea to be 2.64%, or approximately 1 in 38 children, and concluded that autism prevalence estimates worldwide may increase when this approach is used to identify children with ASD. "Prevalence of Autism Spectrum Disorder in a Total Population Sample," published today online in the American Journal of Psychiatry ...

NASHVILLE, Tenn. – Imagine an insect repellant that not only is thousands of times more effective than DEET – the active ingredient in most commercial mosquito repellants – but also works against all types of insects, including flies, moths and ants. That possibility has been created by the discovery of a new class of insect repellant made in the laboratory of Vanderbilt Professor of Biological Sciences and Pharmacology Laurence Zwiebel and reported this week in the online Early Edition of the Proceedings of the National Academy of Sciences. "It wasn't something we ...

New research has revealed how infection by a parasitic fungus dramatically changes the behavior of tropical of carpenter ants (species Camponotus leonardi), causing them to become zombie-like and to die at a spot that has optimal reproduction conditions for the fungus. The multinational research team studied ants living high up in the rainforest canopy in Thailand. A paper describing the research will be published in the BioMed Central open-access journal BMC Ecology on 9 May 2011. "The behavior of these infected zombie ants essentially causes their bodies to become an ...

Seven out of ten hospital nurses who took part in a Canadian study used the dorsogluteal (DG) buttock site to administer intramuscular injections - despite the potential risks of sciatic nerve injury - with only 14% using the ventrogluteal (VG) hip site recommended by the nursing literature. The research, published in the May issue of the Journal of Advanced Nursing, found that younger, newer nurses were significantly more likely to follow the latest VG site advice than their older, experienced colleagues. It also discovered that more than one in four nurses using ...

Major progress has been made in reducing the burden of infectious diseases in Brazil as part of a "remarkable" success story for health in the South American country, according to researchers on a series of papers published in The Lancet. After decades of marked social change, including the introduction of unified healthcare for all, Brazil can also celebrate a reduction in mortality from chronic diseases and huge inroads into improving maternal and child health. But the nation still faces problems – including some infectious diseases such as dengue and leishmaniasis, ...

CHAPEL HILL, N.C. – A new study of U.S. veterans ages 70 and older finds that the healthiest get the most benefit from current colon cancer screening methods. However, for many less healthy veterans the burdens of screening may outweigh the benefits. "This study shows that we really need to target screening in older adults, so that those who will benefit do get screened and followed-up while those who won't benefit aren't exposed to unnecessary burdens," said Christine E. Kistler, MD, assistant professor of Family Medicine at the University of North Carolina at Chapel ...

Steganography is a form of security through obscurity in which information is hidden within an unusual medium. An artist might paint a coded message into a portrait, for instance, or an author embed words in the text. A traditional paper watermark is a well-known example of steganography in action. At first glance, there would appear to be nothing unusual about the work, but a recipient aware of the presence of the hidden message would be able to extract it easily. In the computer age, steganography has become more of a science than an art. Those intent on hiding information ...

Flying the EU flag on public buildings on Europe Day (Monday, 9th May) has no impact on public attitudes to the EU. But EU symbols used in practical ways such as at airport passport controls can polarise attitudes to the EU amongst the Scots and Welsh, according to a study conducted by researchers at the University of Strathclyde, but have little impact on people in England. The research suggests that a split in the UK Coalition on whether to fly the EU flag over public buildings in Whitehall ( http://www.bbc.co.uk/news/uk-politics-13321460) would be based on unfounded ...

The creation of a post-mortem tissue archive for a study of the human form of mad cow disease failed because of a "misguided" refusal by coroners to participate. The Coroners' Society of England and Wales (CSEW) did not recognise its "moral obligation to protect public health" from potential new risks associated with variant Creutzfeldt-Jakob disease (vCJD) when it decided not to allow the collection of tissue from autopsies. That is the conclusion of a paper co-written by a researcher at the London School of Hygiene & Tropical Medicine, which has been published online ...

Are clothing manufacturers helping to turn young girls into sex objects? According to a new study, up to 30 percent of young girls' clothing available online in the US is 'sexy' or sexualizing. The study was carried out by Samantha Goodin, a former Kenyon College (Ohio, USA) student and a research team led by Dr. Sarah Murnen, Professor of Psychology at Kenyon College. In their view, this has serious implications for how girls evaluate themselves according to a sexualized model of feminine physical attractiveness. It makes them confront the issue of sexual identity at a ...

WHAT: Scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), report that they have developed a method—10,000 times more sensitive than other methods—to detect variant Creutzfeldt-Jacob disease (vCJD) in blood plasma. vCJD is a type of prion disease in humans that leads to brain damage and death. The NIAID researchers also used the test to rapidly detect scrapie, a prion disease of sheep, in infected hamsters, some pre-symptomatic. Prion diseases, also known as transmissible spongiform encephalopathies, ...

"At present, it can take up to a year before a patient is diagnosed with SLE. This is because the symptoms are diffuse and are often mistaken for other diseases. However, with this blood-based test, it is possible to determine quickly whether someone has the disease or not", says Christer Wingren, associate professor in Immunotechnology at CREATE Health, Lund University. The test can also determine how far the disease has progressed. There are three different variants of SLE, and all require different treatment. With current methods, it is often difficult to find out ...

ESA's Herschel infrared space observatory has detected raging winds of molecular gas streaming away from galaxies. Suspected for years, these outflows may have the power to strip galaxies of gas and halt star formation in its tracks. The winds that Herschel has detected are extraordinary. The fastest is blowing at a speed of more than 1000 km/s, or about 10 000 times faster than the wind in a terrestrial hurricane. This is the first time that such molecular gas outflows have been unequivocally observed in a sample of galaxies. This is an important discovery because ...

'Healthy' smokers experience changes in the gene expression of their lungs similar to that suffered by smokers who have developed Chronic Obstructive Pulmonary Disease (COPD). This is the conclusion of a new study, led by Catalan researchers, which confirms the crucial role that smoking plays in causing these alterations. "Our objective was to analyse the expression of a range of genes in the pulmonary tissue samples of patients with COPD, whether smokers or not, and people who had undergone operations for cancer or lung transplants", Ricardo Bastos, lead author of the ...
