Nerve cells derived from embryonic stem cells and transplanted into mice may lead to improved brain therapies

Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published today in The Journal of Neuroscience.

Quantum dots stop RNA interference in living cells

More than 15 years ago scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.

Genetic mutation and cat exposure at birth may increase a child's risk of developing eczema

A gene mutation and cat exposure at birth may increase a child's risk of developing eczema during their first year according to a study published in PLoS Medicine. Researchers led by Professor Hans Bisgaard (University Hospital Gentofte, Copenhagen, Denmark) studied the association between mutations in the filaggrin gene (FLG) and exposure to environmental factors with the development of eczema.

New details on how low blood flow promotes vascular disease

Researchers have found the first direct proof that a key protein drives the clogging of arteries in two ways, and that lowering levels of it opens them up, according to study results published in the June edition of the journal Circulation.

Lower blood levels of vitamin D linked to increased heart problems

Individuals with lower blood levels of vitamin D appear to have an increased risk of death overall and from cardiovascular causes, according to a report in the June 23 issue of Archives of Internal Medicine.

New, previously unrecognized source of heart stem cells discovered

Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells. These stem cells, located in the surface of the heart, or epicardium, advance the hope of being able to regenerate injured heart tissue.

New way to limit gene transfer and expression

Researchers from Northwestern University and Texas A & M University have discovered a new way to limit gene transfer and expression to specific tissues in animals.

Could Gleevec help stroke victims?

For over a decade, the drug called tPA has proven its worth as the most effective emergency treatment for the most common kind of stroke. But its promise is blemished by two facts: tPA can cause dangerous bleeding in the brain, and its brain-saving power fades fast after the third hour of a stroke.

Discovery of possible new way to block inflammation in autoimmune disease

Researchers from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health (NIH), have identified a promising new target for autoimmune disease treatment - a cell-surface receptor called DR3.

Discovery of new biomarkers for growth hormone - potential for detecting growth hormone abuse

Researchers have found potential new biomarkers for growth hormone, which they say could help the sports community in detecting growth hormone abuse. The results of the animal study will be presented at The Endocrine Society's 90th Annual Meeting in San Francisco.

Five common genetic variations linked to metabolic syndrome and HDL cholesterol levels

Nutrition researchers at Washington University School of Medicine in St. Louis have identified five common genetic variations that increase the risk of metabolic syndrome, a group of factors linked to heart disease and diabetes. Another variant they found appeared to protect against the condition.

High-carb and protein big breakfast diet shown as a good method to reduce weight

Researchers have found a possible way to overcome the common problem of dieters eventually abandoning their diet and regaining the weight they lost. Eat a big breakfast packed with carbohydrates ("carbs") and protein, then follow a low-carb, low-calorie diet the rest of the day, the authors of a new study recommend. Results were presented Tuesday, June 17, at The Endocrine Society's 90th Annual Meeting in San Francisco.

Scientists identify proteins in mice that might act as biomarkers for growth hormone

Ohio University scientists have identified several proteins in mice that might act as biomarkers for growth hormone. The research could be the first step to finding a more reliable way to detect recombinant human growth hormone (rhGH), which some athletes and teenagers use illegally to boost muscle and reduce fat.

Like father like son - history of heart attacks in the family

Scientists know that heredity plays an important role in causing heart attacks. However the exact genetic mechanisms that transmit the risk of heart attacks from generation to generation still elude them.
