Illuminating neuron activity in 3-D: New technique lets scientists monitor small worm's entire nervous system

Posted: 18 May 2014 01:44 PM PDT

Researchers have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D movies of entire brains at the millisecond timescale, could help scientists discover how neuronal networks process sensory information and generate behavior.

Windshield washer fluid a source of Legionnaires: Found in most school buses

Posted: 18 May 2014 01:44 PM PDT

A form of bacteria responsible for respiratory illness, including the deadly pneumonia known as Legionnaire's disease, may be able to grow in windshield washer fluid and was isolated from nearly 75 percent of school buses tested in one district in Arizona, according to new research.

Bacteria in mouth may diagnose pancreatic cancer

Posted: 18 May 2014 01:44 PM PDT

Patients with pancreatic cancer have a different and distinct profile of specific bacteria in their saliva compared to healthy controls and even patients with other cancers or pancreatic diseases, according to new research. These findings could form the basis for a test to diagnose the disease in its early stages.

Study debunks common myth that urine is sterile: Bacterial differences found in urine of healthy women and women with overactive bladder

Posted: 18 May 2014 01:43 PM PDT

Bacteria live in the bladders of healthy women, discrediting the common belief that normal urine is sterile. This study also revealed that bladder bacteria in healthy women differ from the bladder bacteria in women affected by overactive bladder, which causes a sudden need to urinate.

Clinicians urged to consider spironolactone in HFPEF despite TOPCAT results

Posted: 18 May 2014 06:27 AM PDT

Clinicians have been urged to consider using spironolactone in their patients with heart failure and preserved ejection fraction (HFPEF) after a post-hoc analysis of the TOPCAT trial showed benefit in patients from the Americas. TOPCAT randomized 3445 patients with HFPEF to receive spironolactone, a mineralocorticoid receptor antagonist, at a dose of 15-45mg per day or placebo on top of usual care. Patients were recruited from 270 medical centres in 6 countries.

Heart failure hospitalization more than doubles in IBD flares

Posted: 18 May 2014 06:27 AM PDT

Heart failure hospitalization more than doubles during inflammatory bowel disease (IBD) flares, according to a study of more than 5 million people. "We found that patients with new-onset IBD had a 37% increased risk of hospitalization for heart failure during a mean follow-up of 6.4 years compared to the healthy population. But the risk more than doubled during periods of IBD activity," a researcher noted.

Cardiovascular diseases rise during Greek financial crisis

Posted: 18 May 2014 06:27 AM PDT

Hospital admissions for cardiovascular diseases increased during the Greek financial crisis, according to two studies from Athens. The researchers retrospectively analyzed all admissions to the cardiology department of a hospital in Athens during two time periods. The first time period, 2003 to 2007, was defined as the pre-crisis period, while 2008 to 2012 was the crisis period.

Transgenic mice produce both omega-3, omega-6 fatty acids on carbohydrate diet

Posted: 16 May 2014 05:32 PM PDT

A transgenic mouse has been developed that synthesizes both the omega-3 and omega-6 essential fatty acids within its tissues on a diet of carbohydrates or saturated fats. Significant evidence suggest that the ratio of dietary omega-6 to omega-3 has important implications for human health, further increasing interest in the development of foods rich in omega-3s.

Breakthrough in HIV/AIDS research gives hope for improved drug therapy

Posted: 16 May 2014 05:32 PM PDT

The first direct proof of a long-suspected cause of multiple HIV-related health complications was recently obtained by a team of researchers. The finding supports complementary therapies to antiretroviral drugs to significantly slow HIV progression. The study found that a drug commonly given to patients receiving kidney dialysis significantly diminishes the levels of bacteria that escape from the gut and reduces health complications in non-human primates infected with the simian form of HIV.

MicroRNA that could be used to suppress prostate cancer progression found

Posted: 16 May 2014 05:32 PM PDT

About one in seven men will develop prostate cancer over the course of a lifetime, and about one in 36 men will die from it. This is why findings by researchers, showing that a tumor suppressive microRNA, when activated by an anti-estrogen drug, could contribute to development of future targeted therapies, are important.

New early warning system predicts dengue fever risk during the football World Cup in Brazil

Posted: 16 May 2014 05:29 PM PDT

For the first time, scientists have developed an early warning system to predict the risk of dengue infections for the 553 microregions of Brazil during the football World Cup. The estimates show that the chance of a dengue outbreak is enough of a possibility to warrant a high-alert warning in the three northeastern venues (Natal, Fortaleza, and Recife) but is likely to be generally low in all 12 host cities.

Many Smokers Still Surprised by Facts About Tobacco's Dangers

Posted: 15 May 2014 12:38 PM PDT

Between half and one-third of smokers presented with corrective statements about the dangers of smoking indicated that some of the information was new to them and motivated them to quit, finds a new study. "The tobacco industry systematically deceived the public for decades, denying that smoking was dangerous or addictive," explained one of the study's authors, adding that cigarette makers were actually designing their products to be more addictive to increase sales.
