EMA says link between narcolepsy and Pandemrix 2009 H1N1 vaccine exists

A final review result from Europe's drug regulatory agency released a positive link between narcolepsy and the Pandemrix 2009 H1N1 vaccine. The agency recommends a labeling change that limits the vaccine's use in children and teens to when protection is needed and seasonal trivalent vaccine isn't available.

Taller women more prone to cancer: Study

New research has shown that taller women could be more prone to suffering from cancer. The British study published online in the medical journal The Lancet on Thursday said cancer risk rose about 16% for every 4-inch rise in height. Increasing height heightened the chances of cancers of breast, ovary, womb, bowel, leukemia and malignant melanoma (skin cancer) the study found.

Neogen develops new pathogen DNA detection method for E. coli strains

Neogen Corporation has announced the development of a breakthrough pathogen detection and identification technology that provides next day, DNA-specific test results for seven pathogenic E. coli strains. The technology could be adapted to target almost any bacterium of concern in almost any food sample type.

Researchers discover novel combination of two mutations in a patient with ADHD

Often enough, in science as in life, unexpected knowledge has a personal impact. Researchers seeking rare gene variants in just a few individuals with attention-deficit hyperactivity disorder (ADHD) discovered that one patient had a novel combination of two mutations.

World's best genetic map now built in African-Americans

A group of researchers from the University of Oxford, Harvard Medical School and the University of Mississippi Medical Center has constructed the world's most detailed genetic map, a tool scientists can use to better understand the roots of disease and how DNA is passed generationally to create diversity in the human species.

Researchers develop mouse model of rare human birth defect

A team of researchers from the University of Utah and Brigham Young University has developed a mouse model of focal dermal hypoplasia, a rare human birth defect that causes serious skin abnormalities and other medical problems. This animal model not only provides insight into studying the cause of focal dermal hypoplasia (FDH), but also offers a novel way to study a signaling pathway that is crucial for embryonic development.

Genetically engineered excitable cells made to generate and pass electrical current

By altering the genetic makeup of normally "unexcitable" cells, Duke University bioengineers have turned them into cells capable of generating and passing electrical current.

Essential criteria for clinical diagnosis of restless legs syndrome

We've all experienced abnormal sensations in our legs at one time or another, but for as many as 10 percent of the US population, restless legs syndrome (RLS) is a daily occurrence. Characterized by throbbing, pulling, tingling, itching, and crawling sensations, RLS is a neurological disorder that produces unpleasant physical sensations in the extremities and an urge to counteract that sensation by movement.

Loss of critical male development gene causes male cells to become female

University of Minnesota Medical School and College of Biological Sciences researchers have made a key discovery showing that male sex must be maintained throughout life.

Inherited forms of Alzheimer's could be detected long before memory problems develop

Inherited forms of Alzheimer's disease may be detectable as many as 20 years before problems with memory and thinking develop, scientists will report July 20, 2011, at the Alzheimer's Association International Conference on Alzheimer's Disease in Paris.

U.S. News ranks University of Texas MD Anderson as leading hospital for cancer care

For the fifth straight year, The University of Texas MD Anderson Cancer Center is the leading hospital in the nation for cancer care, according to the "Best Hospitals" survey published annually by U.S. News & World Report magazine.

Computer modeling to predict how peripheral nerve axon responds to electrical stimuli

Researchers at Case Western Reserve University have developed a computer modeling method to accurately predict how a peripheral nerve axon responds to electrical stimuli, slashing the complex work from an inhibitory weeks-long process to just a few seconds.

Researchers influence activity of nerve cells with laser light

Unlike conventional methods, with the so-called optogenetics, the researchers are able to target one cell type. "We are now going to use this method to find out exactly what goes wrong in the nerve cells in movement disorders such as ataxias", said Prof. Dr. Stefan Herlitze.

Researchers identify IDOL protein as potential new target for lowering LDL cholesterol

High levels of 'bad' cholesterol (LDL cholesterol) are a risk factor for developing atherosclerotic cardiovascular disease (ASCVD) - a disease of the major arterial blood vessels that is one of the major causes of heart attack and stroke.

Intense visual stimulation renders nerve cells more receptive to subsequent learning

Dr. Ed Ruthazer is a mapmaker but, his landscape is the developing brain - specifically the neuronal circuitry, which is the network of connections between nerve cells. His research at The Montreal Neurological Institute and Hospital - The Neuro at McGill University, reveals the brain as a dynamic landscape where connections between nerves are plastic, changing and adapting to the demands of the environment.

Humans and zebrafish share mechanisms that regulate the circadian system

Circadian rhythms - the natural cycle that dictates our biological processes over a 24-hour day - does more than tell us when to sleep or wake. Disruptions in the cycle are also associated with depression, problems with weight control, jet lag and more. Now Prof. Yoav Gothilf of Tel Aviv University's Department of Neurobiology at the George S. Wise Faculty of Life Sciences is looking to the common zebrafish to learn more about how the human circadian system functions.
