Sophia Antipolis, France, Sunday 15 May 2011: The European Society of Cardiology (ESC) is calling for a single, co-ordinated European system to oversee the evaluation and approval of medical devices. The call is being made in a paper published online in the European Heart Journal reporting on a conference held by the ESC in January 2011 looking to increase the input of medical experts in developing medical device policy.
Stem cell research courts both controversy and support in the community- depending on your viewpoint.
Now, for the first time, scientists at Monash University's Immunology and Stem Cell Laboratories (MISCL) have shown that they can make human stem cells from healthy adult kidneys without working on human embryos, circumventing ethical concerns around this research.
With an increasingly warmer climate, there is a trend for springs to arrive earlier and summers to be hotter. Since spring and summer are the prime growing seasons for plants—when flowers bloom and trees increase in girth and height—do these climate changes mean greater seasonal growth for plants? This is a critical question for forest management, especially in the boreal region—an area particularly sensitive to the effects of climate change.
Scientists working with Professor Dr. Joachim L. Schultze have identified over 480 molecules whose concentration in the blood changes when a person develops lung cancer. These molecules are present in the blood cells either in increased or decreased quantities. "In lung cancer patients, typical patterns which can be detected with a measuring program thus emerge", explains Prof. Schultze. The molecules are nucleic acids which form in the body when certain genes are transcribed.
cientists have identified a class of naturally occurring bacteria that can strongly inhibit malaria-causing parasites in Anopheles mosquitoes, a finding that could have implications for efforts to control malaria. The study, led by George Dimopoulos, Ph.D., of the Bloomberg School of Public Health and the Malaria Research Institute, both of Johns Hopkins University, Baltimore, appears in the May 13 edition of Science. The research was partly funded by the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health.
A research team has discovered that billions of years before life evolved in the oceans, thin layers of microbial matter in shallow water produced enough oxygen to support tiny, mobile life forms.
The researchers say worm-like creatures could have lived on the oxygen produced by photosynthetic microbial material, even though oxygen concentrations in the surrounding water were not high enough to support life. The research was conducted in shallow lagoons in Venezuela where the high salt content is comparable to oceans older than 500 million years.
WASHINGTON, D.C. (May 15, 2011)––With an increase in abdominal imaging over the past decade, there has been an increase in the detection of incidental kidney cancer, which has led to concerns that we may be over-treating indolent disease. As part of this effort, clinicians have started to investigate the effectiveness of active surveillance (AS), or close observation as opposed to immediate surgery, for select patients with small renal masses (SRMs).
PHILADELPHIA, PA (May 16, 2011)––Today's anticancer drugs often work wonders against malignancies, but sometimes tumors become resistant to the effects of such drugs, and treatment fails. Medical researchers would like to find ways of counteracting such resistance, but first they must understand why and how it happens. New findings by Fox Chase Cancer Center researchers identify one protein, Abcc10 (also known as Mrp7), as being intimately involved in resistance to certain drugs used to treat breast, ovarian, lung, and other cancers.
Toronto - Why isn't knowledge transfer happening more often in companies spending money on it?
Maybe it's because their staff don't always want to share.
"We've had years of research in organizations about the benefits of knowledge-sharing but an important issue is the fact that people don't necessarily want to share their knowledge," says David Zweig, a professor of organizational behaviour and human resources management at the University of Toronto's Rotman School of Management and the University of Toronto at Scarborough.
Boston (May 16, 2011) – Most degenerative diseases begin with a gradual loss of specific cell types that progresses, eventually leading to symptoms. For example, in type I diabetes, hyperglycemia commonly develops when approximately 80 percent of the beta cells in the pancreas are lost; in Parkinson's disease, motor dysfunction typically begins when neurons in a certain portion of the brain are decreased by 70 to 80 percent. Finding ways to stop early cell destruction is vital, but methods to do so have proven challenging because of limitations of models for early stages of cell loss.
WINSTON-SALEM, N.C. – Monday, May 16, 2011 – A new discovery in mice by researchers at Wake Forest Baptist Medical Center may one day allow doctors to spare some patients with acute myeloid leukemia (AML) from toxic treatments, while also opening the door for new therapeutic research.
AML, the most common form of acute leukemia seen in adults, is an aggressive form of cancer that primarily affects the elderly. Despite years of research, outcomes for most patients remain poor, particularly for one subset of patients with a specific mutation of the FLT3 receptor.
Climbing is possibly one of the riskiest things an adult tarantula can do. Weighing in at anything up to 50gm, the dry attachment systems that keep daintier spiders firmly anchored are on the verge of failure in these colossal arachnids. 'The animals are very delicate. They wouldn't survive a fall from any height,' explains Claire Rind from the University of Newcastle, UK. In 2006, Stanislav Gorb and his colleagues published a paper in Nature suggesting that tarantulas may save themselves from falling by releasing silk threads from their feet.
MAY 16, 2011 – Critical new research has found that lesbian, gay, bisexual, and transgender (LGBT) youth who experience high levels of school victimization in middle and high school report impaired health and mental health in young adulthood, including depression, suicide attempts that require medical care, sexually transmitted diseases (STDs) and risk for HIV.
Satellite tracking of olive ridley sea turtles off the coast of Central Africa has revealed that existing protected areas may be inadequate to safeguard turtles from fishing nets, according to scientists with the University of California-Santa Cruz, the Wildlife Conservation Society, the University of Exeter, and others. Scientists involved in the study recommended the extension of an international marine park that spans the waters of Gabon and the Republic of Congo and better international cooperation to manage this threatened species.
