Multidrug-resistant bacteria from chickens pose risk to human health Posted: 04 Nov 2016 04:13 PM PDT Isolates of a common poultry pathogen collected from animals in Indian bird markets were found to be mostly resistant to multiple classes of antibiotics. The study provides the first data on prevalence and isolation of Helicobacter pullorum in India.

Laser particles could provide sharper images of tissues Posted: 04 Nov 2016 04:09 PM PDT A new imaging technique stimulates particles to emit laser light and could create higher-resolution images of living tissues, say scientists.

12-week exercise program significantly improved testosterone levels in overweight, obese men Posted: 04 Nov 2016 04:05 PM PDT Twelve weeks of aerobic exercise significantly boosted testosterone levels in overweight and obese men, according to researchers. Increased levels were highest among men who exercised vigorously, report investigators.

Study challenges model of Alzheimer's disease progression Posted: 04 Nov 2016 11:58 AM PDT Researchers provide unprecedented evidence that basal forebrain pathology precedes and predicts both entorhinal pathology and memory impairment in people with Alzheimer's disease.

Brain needs to be retrained after ACL injury Posted: 04 Nov 2016 11:58 AM PDT Regaining full function after an anterior cruciate ligament (ACL) injury is more than just physical -- it requires retraining the brain, say researchers.

Chicago wouldn’t last long under zombie invasion, model finds Posted: 04 Nov 2016 09:05 AM PDT In the unlikely event of the zombie apocalypse, it would take less than two months for the undead to take control of the city, says a new study.

Researchers find immunotherapy treatments better for advanced skin cancer Posted: 04 Nov 2016 08:36 AM PDT A research team evaluated 15 randomized controlled trials published between 2011 and 2015, assessing the benefits and harms of targeted or immune checkpoint inhibitors in 6,662 patients with cancer that had spread to the lymph nodes and surgery was not an option, or distant metastatic melanoma.

The brain can reveal drinking status even after death Posted: 04 Nov 2016 07:24 AM PDT Scientists who use postmortem brain tissue to study alcohol's effects on brain structure and function will find this research interesting. Phosphatidylethanol (PEth) is an alcohol metabolite and its concentration in whole blood samples is a biomarker of drinking habits. For this study, scientists examined PEth levels in postmortem brains of individuals known to have had alcohol use disorders (AUDs).

Receptor that may allow HIV to infect kidney cells identified Posted: 04 Nov 2016 07:24 AM PDT New research suggests that transmembrane TNF-alpha may allow HIV to infect kidney cells that not express the major HIV-1 CD4 receptor. The findings could provide insights on how patients develop HIV-1 associated nephropathy.

New study shows balloon in a capsule helps patients lose nearly twice as much weight than diet, exercise and lifestyle therapy alone Posted: 04 Nov 2016 07:23 AM PDT Patients with obesity who swallowed gas-filled balloon capsules designed to help them eat less, lost 1.9 times more weight than patients who relied on diet, exercise and lifestyle therapy alone, according to new research.

Male sleep habits may increase risk of cancer Posted: 04 Nov 2016 07:20 AM PDT Men who have worked night shifts for more than 20 years, or who work night shifts without daytime napping, or sleep for more than ten hours per night on average may have an increased risk of cancer, according to a new study.

Weight loss after obesity doesn’t cut risk of certain types of cancer Posted: 03 Nov 2016 01:03 PM PDT Losing weight may not protect against colon and liver cancer, even though obesity is associated with increased risk of certain types of gastrointestinal malignancy.

New computational tool may speed drug discovery Posted: 03 Nov 2016 11:34 AM PDT A new computational tool called fABMACS is helping scientists see beyond static images of proteins to more efficiently understand how these molecules function, which could ultimately speed up the drug discovery process.

Eleven substances added to 14th Report on Carcinogens Posted: 03 Nov 2016 09:46 AM PDT The recent release of the U.S. Department of Health and Human Services 14th Report on Carcinogens includes seven newly reviewed substances, bringing the cumulative total to 248 listings.

Faster diagnosis of sepsis pathogens Posted: 03 Nov 2016 08:51 AM PDT Microbial pathogens can be diagnosed unambiguously and within just 24 hours by means of high-throughput sequencing of their genetic makeup and special bioinformatics evaluation algorithms. Researchers have validated this in a clinical study with sepsis patients.

Insurance coverage of obesity, lack of formal diagnosis emerge as top barriers to getting professional weight loss help Posted: 03 Nov 2016 06:12 AM PDT Improving health insurance coverage for weight loss services could help people struggling with obesity lose weight, according to a new survey of non-physician health professionals (HPs). A second study found that three out of four patients are affected by obesity or overweight, yet less than half (48%) of these patients with a BMI higher than 30 received a formal diagnosis of obesity.

Eating dinner early, or skipping it, may be effective in fighting body fat Posted: 03 Nov 2016 06:12 AM PDT The first human test of early time-restricted feeding found that this meal-timing strategy strategy reduced swings in hunger and altered fat and carb burning patterns, which may help with losing weight. In early time-restricted feeding (eTRF), people eat their last meal by the mid-afternoon and don't eat again until breakfast the next morning.
