Genetic Therapy Reverses Heart Disease in Mice

(NEWSER) - The entire structure of the virus that causes AIDS has been decoded for the first time, a breakthrough that may eventually lead to effective treatments for the disease and others like it, Reuters reports. University of North Carolina researchers, using a new method they liken to zooming out on a map to get the big picture, say they believe the discovery will lead to effective new drugs for HIV and for other viruses that work through RNA rather than DNA, including influenza and the common cold.

Periodontitis patients should cut out risk factors, scientists say

(NEWSER) - Scientists have identified a link between gum disease and heart disease, the BBC reports, finding the same genetic variation in a group of patients with heart disease and a group with severe periodontitis. “Now we know for sure that there is a strong genetic link, patients with periodontitis should try to reduce their risk factors … at an early stage,” said the head researcher.

Mice who consumed equivalent of 6-8 cups a day were protected

(NEWSER) - For preventing the autoimmune disease multiple sclerosis, caffeine might be just what the doctor ordered, the Daily Telegraph reports. In a study involving what must have been some very jittery mice, researchers found that the equivalent of 6-8 cups of coffee per day conferred protection from the rodent equivalent of MS. Don't rush off to Starbucks yet, though. More»

Six variants each add risk for developing the disease

(NEWSER) - Scientists pooling data from European and US studies have identified six more genes associated with a higher risk of type 2 diabetes, the Guardian reports. The study, published in Nature Genetics, found small but significant connections between the genes and the disease, with certain genetic variants linked to a 10-15% increase in risk. Researchers hope the discovery can lead to developments in prevention and treatment. More»

Advance could save heart disease patients, regrow other organs

(NEWSER) - Scientists rebuilt rat and pig hearts using stem cells taken from the recipients themselves, the Telegraph reports—a medical breakthrough that could help the 22 million people who suffer from heart failure worldwide. The technique, called whole organ decellularization, produced the world’s first functioning “bioartificial” heart within eight days after researchers injected it with fresh stem cells. More»
