Faster, more accurate diagnostic test for Sjogren's syndrome

Researchers in Japan are developing a faster, more accurate diagnostic test for Sjögren’s (SHOW-grins) syndrome, an incurable autoimmune disorder characterized by chronically dry eyes and dry mouth.

Researchers discover mechanism by which tumours support their own growth

In a recent issue of the American Journal of Pathology, the Bremen researchers report their findings on a signalling molecule called "High Mobility Group Protein B1" (HMGB1). As a signal sent by tumour cells HMGB1 proteins induce sprouting of blood vessels that supply tumours with oxygen, thus promoting tumour growth.

New blood test improves the ability to diagnose or exclude congestive heart failure

A new blood test that measures a particular marker of cardiac distress can markedly improve the ability to diagnose or exclude congestive heart failure in patients with shortness of breath who come to hospital emergency departments.

Research suggests a central role for NMDA receptors in learning and memory

Learning and memory are processes that link experience with behavior and therefore play central roles in our daily experience. That there exists a physical basis for these processes seems at first hard to imagine--except for the fact that physical disruptions in the brain, such as stroke or disease, can make them go wrong.

Moderate levels of exercise may not be enough to control mild hypertension

Moderate levels of exercise may not be enough to control mild hypertension in men and women over age 55, the age group most at risk of later developing potentially fatal heart failure, a new four-year study reports. The findings by researchers at Johns Hopkins, to be published in the journal Archives of Internal Medicine online April 11, call into question the effectiveness of national guidelines on exercise for lowering blood pressure in older people.

Eat like the Greeks and live longer

Researchers at the University of Athens Medical School, in a major pan-Europe study, have produced convincing evidence that a Mediterranean diet rich in vegetables and fruit and low in saturated fats can help us live longer.

Novel human kidney protein called renalase that regulates both heart contraction and blood pressure

Researchers at Yale School of Medicine and the VA Connecticut Healthcare System in West Haven identified a novel human kidney protein called renalase that regulates both heart contraction and blood pressure; it is a strong candidate for easily administered treatment of advanced kidney and cardiovascular disease.

Findings could lead to improved treatments for schizophrenics, amphetamine abusers

An Oregon Health & Science University researcher is among an international team closing in on why many people with schizophrenia and other psychotic disorders are "supersensitive" to the powerful neurotransmitter dopamine.

The liver may produce most of the body's good cholesterol

Research in mice suggests that the liver may produce most of the body's "good" cholesterol, an unexpected finding that might one day help scientists develop new treatments to raise levels of this heart-protecting molecule in humans.

Anti-poverty program substantially increased marriage rates among single mothers who have never been married

An anti-poverty program in Milwaukee, Wisc., substantially increased marriage rates among single mothers who have never been married, according to research by New York University psychology professor Hiro Yoshikawa and Anna Gassman-Pines, a doctoral candidate in psychology.

First identified gene to link autoimmune diseases with cardiovascular diseases

A common gene variant has been identified as the risk factor behind a number of common diseases by research scientists at Karolinska Institutet and the Centre for Molecular Medicine (CMM), Stockholm, Sweden. Up to a quarter of the population could be affected.

Assessing the function of unknown genes is feasible and can be done with a microarray phenotype

Microarrays provide a method of quantifying the expression and order of genes in a particular genome -- acting as a surrogate measure of cell physiology, said researchers at Baylor College of Medicine in a report that appears online today in the journal Nature Genetics.

Vigorous exercise can slow down arthritis

Almost 60 percent of Americans age 65 and older suffer from some form of arthritis, a progressive joint disease which is the leading cause of disability in the United States. For more than 1 in 10 sufferers, arthritis makes simple, everyday tasks, from walking up a flight of stairs to bathing and dressing, extremely difficult and by 2010, the disease is expected to affect almost 40 million Americans over age 65, increasing the ranks of senior citizens with disabilities that limit independent living.

Men who drink milk at more risk of Parkinsons disease

Korean University researchers say drinking a glass or two of milk a day may increase the risk of Parkinson's disease in middle-aged men, but the apparent link is unlikely to be due to milk's main nutritional ingredient, calcium.

Depression overtakes back pain for incapacity benefit claims

Common mental disorders, such as depression and anxiety, now account for more incapacity benefit claims than musculoskeletal conditions like low back pain, say researchers in this week’s BMJ.

Make room for daddy, say University of Florida autism experts

Autism is a developmental disability that typically appears during the first three years of life and is characterized by problems interacting and communicating with others. Caring for an autistic child can be a relentless and labor-intensive task — one that is overwhelmingly performed by mothers, says UF nursing researcher Jennifer Elder.

Researchers shed light on the brain cell damage caused by Alzheimer's disease

The researchers hope that by gaining a better understanding of the disease's cellular impacts, progress can be made towards developing a treatment. The research is reported in the current edition of the Journal of Alzheimer's Disease, published by IOS publishers.
