Mechanism that repairs brain after stroke discovered
- Details
- Category: Research
A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered at Lund University and Karolinska Institute in Sweden. The findings have been published in the journal Science. A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to an interruption of blood flow and therefore a shortage of oxygen.
Probiotic yogurt could help protect against heavy metal poisoning

- Category: Research
New research shows probiotic yogurt can reduce the uptake of certain heavy metals and environmental toxins by up to 78% in pregnant women. Led by Scientists at Lawson Health Research Institute's Canadian Centre for Human Microbiome and Probiotic Research, this study provides the first clinical evidence that a probiotic yogurt can be used to reduce the deadly health risks associated with mercury and arsenic.

University of Utah biochemists have reported a new drug discovery tool against the Ebola virus. According to a study published in this week's online edition of Protein Science, they have produced a molecule, known as a peptide mimic, that displays a functionally critical region of the virus that is universally conserved in all known species of Ebola.
Attacking type 2 diabetes from a new direction with encouraging results

Type 2 diabetes affects an estimated 28 million Americans according to the American Diabetes Association, but medications now available only treat symptoms, not the root cause of the disease. New research from Rutgers shows promising evidence that a modified form of a different drug, niclosamide - now used to eliminate intestinal parasites - may hold the key to battling the disease at its source.

Nonsteroidal anti-inflammatory drugs (NSAIDs) - such as ibuprofen and aspirin - increase one's risk of upper gastrointestinal bleeding. When taken in combination with other drugs, this risk is significantly higher, according to new research appearing in the October issue of Gastroenterology, the official journal of the American Gastroenterological Association.
New drug-delivery capsule may replace injections
- Details
- Category: Research
Given a choice, most patients would prefer to take a drug orally instead of getting an injection. Unfortunately, many drugs, especially those made from large proteins, cannot be given as a pill because they get broken down in the stomach before they can be absorbed. To help overcome that obstacle, researchers at MIT and Massachusetts General Hospital (MGH) have devised a novel drug capsule coated with tiny needles that can inject drugs directly into the lining of the stomach after the capsule is swallowed.
