Genetic cause of common breast tumors found

Genetic cause of common breast tumors found

A multi-disciplinary team of scientists from the National Cancer Centre Singapore, Duke-NUS Graduate Medical School Singapore, and Singapore General Hospital have made a major breakthrough in understanding the molecular basis of fibroadenoma, one of the most common breast tumors diagnosed in women.

High-dose fluticasone effective against eosinophilic esophagitis, study shows

High-dose fluticasone effective against eosinophilic esophagitis, study shows

Results from a clinical trial show that high doses of the corticosteroid fluticasone propionate safely and effectively induce remission in many people with eosinophilic esophagitis (EoE), a chronic inflammatory disease of the esophagus characterized by high levels of white blood cells called eosinophils. However, some trial participants did not respond to fluticasone even after six months of high-dose treatments, providing evidence that certain people with EoE are steroid-resistant. Continue reading

Eating lean beef daily can help lower blood pressure, study suggests

Eating lean beef daily can help lower blood pressure, study suggests

Contrary to conventional wisdom, a growing body of evidence shows that eating lean beef can reduce risk factors for heart disease, according to recent research by nutritional scientists. “This research adds to the significant evidence, including work previously done in our lab, that supports lean beef’s role in a heart-healthy diet,” said Penny M. Kris-Etherton, Distinguished Professor of Nutrition, Penn State. Continue reading

One injection stops diabetes in its tracks: Treatment reverses symptoms of type 2 diabetes in mice without side effects

One injection stops diabetes in its tracks: Treatment reverses symptoms of type 2 diabetes in mice without side effects

In mice with diet-induced diabetes — the equivalent of type 2 diabetes in humans — a single injection of the protein FGF1 is enough to restore blood sugar levels to a healthy range for more than two days. The discovery by Salk scientists, published today in the journal Nature , could lead to a new generation of safer, more effective diabetes drugs Continue reading

Marijuana dependence alters the brain’s response to drug paraphernalia

Marijuana dependence alters the brain’s response to drug paraphernalia

New research from The University of Texas at Dallas demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users. The study, published July 1 in Drug and Alcohol Dependence , demonstrated that different areas of the brain activated when dependent and non-dependent users were exposed to drug-related cues. The 2012 National Survey on Drug Use and Health shows marijuana is the most widely used illicit drug in the United States. Continue reading

Health risks posed by ‘third hand’ tobacco smoke

Health risks posed by ‘third hand’ tobacco smoke

Research led by the University of York has highlighted the potential cancer risk in non-smokers — particularly young children — of tobacco smoke gases and particles deposited to surfaces and dust in the home. Until now, the risks of this exposure known as ‘third hand tobacco smoke’ have been highly uncertain and not considered in public policy. However, a new study published in the journal Environment International, has estimated for the first time the potential cancer risk by age group through non-dietary ingestion and dermal exposure to third hand smoke Continue reading

Live kidney donors face ‘pointless’ insurance troubles

Live kidney donors face ‘pointless’ insurance troubles

Healthy living kidney donors often face pointless post-donation hurdles when seeking or changing health or life insurance, according to results of a new study by Johns Hopkins researchers. “Living donors are some of the healthiest people in the United States Continue reading

Live kidney donors face ‘pointless’ insurance troubles

Healthy living kidney donors often face pointless post-donation hurdles when seeking or changing health or life insurance, according to results of a new study by Johns Hopkins researchers. “Living donors are some of the healthiest people in the United States. They’re heavily screened before they’re approved for donation and should be easily insurable,” says study leader Dorry Segev, M.D., Ph.D., M.H.S., an associate professor of surgery and epidemiology at The Johns Hopkins University Continue reading

Hidden Variations in Neuronal Networks May Explain Differences In Traumatic Brain Injury Outcomes

Hidden Variations in Neuronal Networks May Explain Differences In Traumatic Brain Injury Outcomes

A team of researchers at the Neuroscience Institute at Georgia State University has discovered that hidden differences in the properties of neural circuits can account for whether animals are behaviorally susceptible to brain injury. These results could have implications for the treatment of brain trauma Continue reading
