Skin, soft tissue infections succumb to blue light

2013-01-29

Blue light can selectively eradicate Pseudomonas aeruginosa infections of the skin and soft tissues, while preserving the outermost layer of skin, according to a proof-of-principle study led by Michael R. Hamblin of the Massachusetts General Hospital, and the Harvard Medical School, Boston. The research is published online ahead of print in the journal Antimicrobial Agents and Chemotherapy "Blue light is a potential non-toxic, non-antibiotic approach for treating skin and soft tissue infections, especially those caused by antibiotic resistant pathogens," says Hamblin. ...

Injecting botox into stomach does not promote weight loss

2013-01-29

Bethesda, MD (Jan. 28, 2013) – Despite conflicting data in support of the practice, some overweight Americans looking for an easy fix have turned to gastric botox injections to help them lose weight. This month in Clinical Gastroenterology and Hepatology, the official clinical practice journal of the American Gastroenterological Association, researchers from the Mayo Clinic publish a definitive study finding that Botox doesn't promote weight loss. Injecting botulinum toxin A (BTA), or Botox, into the stomach had been believed to delay emptying of the stomach, increase ...

New study shows stable fisher population in the Southern Sierra Nevada

2013-01-29

ARCATA, Calif.—After experiencing years of population decline on the West Coast, a recent study examining fisher populations found that—at least in the southern Sierra Nevada—the animal's numbers appear to be stable. Scientists from the U.S. Forest Service's Pacific Southwest Research Station (PSW) and the Pacific Southwest Region collaborated to monitor the distribution of fishers across a 7,606-square-mile area in the southern Sierra Nevada. They used baited track-plate stations—an enclosure where the fisher leaves a sooted track print as it walks through—at 223 locations ...

Using Twitter to track the flu: A better way to screen the Tweets

2013-01-29

Sifting through social media messages has become a popular way to track when and where flu cases occur, but a key hurdle hampers the process: how to identify flu-infection tweets. Some tweets are posted by people who have been sick with the virus, while others come from folks who are merely talking about the illness. If you are tracking actual flu cases, such conversations about the flu in general can skew the results. To address this problem, Johns Hopkins computer scientists and researchers in the university's School of Medicine have developed a new tweet-screening ...

Eating bright-colored fruits and vegetables may prevent or delay ALS

2013-01-29

New research suggests that increased consumption of foods containing colorful carotenoids, particularly beta-carotene and lutein, may prevent or delay the onset of amyotrophic lateral sclerosis (ALS). The study, published by Wiley in Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, found that diets high in lycopene, beta-cryptoxanthin, and vitamin C did not reduce ALS risk. Carotenoids give fruits and vegetables their bright orange, red, or yellow colors, and are a source of dietary vitamin A. Prior studies report that ...

Scientists trick iron-eating bacteria into breathing electrons instead

2013-01-29

Scientists have developed a way to grow iron-oxidizing bacteria using electricity instead of iron, an advance that will allow them to better study the organisms and could one day be used to turn electricity into fuel. The study will be published on January 29 in mBio®, the online open-access journal of the American Society for Microbiology. The method, called electrochemical cultivation, supplies these bacteria with a steady supply of electrons that the bacteria use to respire, or "breathe". It opens the possibility that one day electricity generated from renewable sources ...

Early menopause may occur in women with BRCA gene, new study finds

2013-01-29

Women with harmful mutations in the BRCA gene, which put them at higher risk of developing breast and ovarian cancer, tend to undergo menopause significantly sooner than other women, allowing them an even briefer reproductive window and possibly a higher risk of infertility, according to a study led by researchers at UC San Francisco. Moreover, the study showed that carriers of the mutation who are heavy smokers enter menopause at an even earlier age than non-smoking women with the mutation. While the authors note that further research is needed, given the size and ...

Study demonstrates health benefits of coming out of the closet

2013-01-29

Lesbians, gays and bisexuals (LGBs) who are out to others have lower stress hormone levels and fewer symptoms of anxiety, depression, and burnout, according to researchers at the Centre for Studies on Human Stress (CSHS) at Louis H. Lafontaine Hospital, affiliated with the University of Montreal. Cortisol is a stress hormone in our body. When chronically strained, cortisol contributes to the 'wear and tear' exerted on multiple biological systems. Taken together, this strain is called "allostatic load". "Our goals were to determine if the mental and physical health of lesbians, ...
