White button mushrooms can keep the immune system healthy: Study

Mushrooms are among the many foods thought to play an important role in keeping the immune system healthy. Now, Agricultural Research Service funded scientists have conducted an animal-model and cell-culture study showing that white button mushrooms enhanced the activity of critical cells in the body's immune system.

Transforaminal injection of steroids is a viable alternative for lumbar radicular pain surgery

A recent study from Australian researchers determined that transforaminal injection of steroids was a viable alternative to surgery for lumbar radicular pain due to disc herniation. Full details of the study appear in the August issue of Pain Medicine, a journal published by Wiley-Blackwell on behalf of the American Academy of Pain Medicine, the Faculty of Pain Medicine of the Australian and New Zealand College of Anaesthetists, and the International Spine Intervention Society.

Supplementation of vitamin D protects vascular systems: Study

Vitamin D deficiency is associated with arterial stiffness, a risk factor for heart disease and stroke, in black teens according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). Black teens taking vitamin D supplementation of 2,000 international units (IU) per day had a decrease in central arterial stiffness.

Prostate basal cell can spawn tumors in prostate gland: Research

A type of prostate cell that has been largely ignored by cancer researchers can, in fact, trigger malignant prostate cancer, according to new studies by Howard Hughes Medical Institute (HHMI) scientists and their colleagues.

New paradigm in TB research may lead to improved vaccination, treatment

Often causing no symptoms in carriers of the disease, worldwide tuberculosis (TB) infects eight to ten million people every year, kills two million, and it is highly contagious as it is spread through coughing and sneezing. "It's a global health disaster waiting to happen, even here in Canada, but this new paradigm in TB research may offer an immediate opportunity to improve vaccination and treatment initiatives," explains Dr. Maziar Divangahi of McGill University and of the Research Institute of the McGill University Health Centre.

Resting brain activity associated with spontaneous fibromyalgia pain

A recent study from researchers at Massachusetts General Hospital and University of Michigan provides the first direct evidence of linkage between elevated intrinsic (resting-state) brain connectivity and spontaneous pain intensity in patients with fibromyalgia (FM).

TNF blockers may increase the risk of malignancy in children

The Food and Drug Administration (FDA) received reports of malignancies in children using tumor necrosis factor a (TNF) blockers, raising concerns of an associated risk and prompting an investigation.

Study examines effects of binge drinking on prospective memory in teenagers

Academics at Northumbria University have demonstrated a link between teenage binge drinking and damage to prospective memory. Prospective memory is an important aspect of day-to-day memory function and is defined as the cognitive ability to remember to carry out an activity at some future point in time. Examples include remembering to attend an appointment at the dentist or to carry out a task such as remembering to pay a bill on time.

New study shows vitamin D deficiency is associated with arterial stiffness

Vitamin D deficiency is associated with arterial stiffness, a risk factor for heart disease and stroke, in black teens according to a new study accepted for publication in The Endocrine Society's www.endo-society.org. Black teens taking vitamin D supplementation of 2,000 international units per day had a decrease in central arterial stiffness.

UCLA study suggests effective approach to cultivate female leadership in medicine

Half of U.S. first-year medical students are female, yet a new UCLA study shows that they volunteer for leadership roles in the classroom significantly less than their male counterparts. Subtle encouragement from teachers, however, can even out the playing field by boosting female students' willingness to identify themselves as leaders.

Researchers examine why some obese people become diabetic while others do not

Why some obese people go on to become diabetic while others do not. It is common to find obese people - even morbidly obese people - who are healthier than their condition would normally allow.

NARSAD to honor five young scientists at Annual Klerman and Freedman Awards event

July 30 NARSAD will honor five outstanding researchers at the Annual Klerman and Freedman Awards event in New York City.

Two middle school students join scientists to research on key bacterial enzyme

Grown-ups aren't the only ones making exciting scientific discoveries these days. Two middle school students from Wisconsin joined a team of scientists who are reporting the first glimpse of the innermost structure of a key bacterial enzyme. It helps activate certain antibiotics and anti-cancer agents so that those substances do their job. Their study appears in ACS' weekly journal Biochemistry.

Researchers find how angiotensin influences immune system

Researchers in Heidelberg and Stanford have discovered a new signalling pathway of brain cells that explains how widely used antihypertensive drugs could keep inflammation in multiple sclerosis in check. The peptide angiotensin not only raises blood pressure but also activates the immunological messenger substance TGF beta on a previously unknown communication pathway in the brain.

Researchers unveil mechanism of cholera bacteria to create cell energy

Researchers have found that an enzyme in the bacteria that causes cholera uses a previously unknown mechanism in providing the bacteria with energy. Because the enzyme is not found in most other organisms, including humans, the finding offers insights into how drugs might be created to kill the bacteria without harming humans.

Scientists identify new targets to develop treatment for HD

Scientists at the Buck Institute for Age Research have discovered that a particular family of enzymes are involved in the breakdown of proteins that modify the production of toxic fragments that lead to the pathology of Huntington's disease. These enzymes, matrix metalloproteinases, provide new targets for drug therapies for the disease - targets that have already been shown to respond to cancer drugs currently in clinical development.

Genetic signals determine neurotransmitter use for communication

Cascades of genetic signals determine which neurotransmitter a brain cell will ultimately use to communicate with other cells. Now a pair of reports from biologists at the University of California, San Diego, have shown for the first time that electrical activity in these developing neurons can alter their chemical fate-and change an animal's behavior-by tweaking this genetic program.

Study reveals high rate of atrial fibrillation in patients with early stages of CKD

Millions of Americans in the early stages of chronic kidney disease (CKD) are at an increased risk of having atrial fibrillation (AF) - a major risk factor for stroke - according to new research by investigators at Wake Forest University Baptist Medical Center.

REM sleep behavior disorder may later lead to neurologic disorders

A new study shows that a sleep disorder may be a sign of dementia or Parkinson's disease up to 50 years before the disorders are diagnosed. The research is published in the July 28, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology.

Loss of key nerve cells cause Parkinson's disease: Research

Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease. This discovery not only may explain how a genetic mutation linked to Parkinson's causes the cells' death, but could also open the door to new therapeutic approaches for the malady.
