One reason brain tumors are more common in men Posted: 01 Aug 2014 06:33 PM PDT New research helps explain why brain tumors occur more often in males and frequently are more harmful. For example, glioblastomas, the most common malignant brain tumors, are diagnosed twice as often in males, who suffer greater cognitive impairments than females and do not survive as long. The researchers found that retinoblastoma protein, a protein known to reduce cancer risk, is significantly less active in male brain cells than in female brain cells.

Chili peppers for a healthy gut: Spicy chemical may inhibit gut tumors Posted: 01 Aug 2014 06:33 PM PDT Researchers report that dietary capsaicin – the active ingredient in chili peppers – produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors.

A map for eye disease: Most detailed molecular map of eye region associated with vision loss Posted: 01 Aug 2014 09:50 AM PDT Vision specialists have created the most detailed molecular map of a region of the human eye associated with disease, including age-related macular degeneration. The map catalogs more than 4,000 proteins in each of three areas of the choroid.

'Normal' bacteria vital for keeping intestinal lining intact Posted: 01 Aug 2014 09:50 AM PDT Scientists have found that bacteria that aid in digestion help keep the intestinal lining intact. The findings could yield new therapies for inflammatory bowel disease and a wide range of other disorders.

Small RNAs in blood may reveal heart injury Posted: 01 Aug 2014 08:58 AM PDT Like clues to a crime, specific molecules in the body can hint at exposure to toxins, infectious agents or even trauma, and so help doctors determine whether and how to treat a patient. In recent years, tiny pieces of RNA called microRNAs have captured scientific attention for their potential as markers of health and disease.

New mothers still excessively sleepy after 4 months, study shows Posted: 01 Aug 2014 07:50 AM PDT New mothers are being urged to be cautious about returning to work too quickly, after a study found one in two were still excessively sleepy four months after giving birth. "Sleep disruption strongly influences daytime function, with sleepiness recognized as a risk-factor for people performing critical and dangerous tasks," an author of the new article said.

Recent use of some birth control pills may increase breast cancer risk, study suggests Posted: 01 Aug 2014 06:12 AM PDT Women who recently used birth control pills containing high-dose estrogen and a few other formulations had an increased risk for breast cancer, whereas women using some other formulations did not, according to new data.

Management of anticoagulant-associated intracerebral hemorrhage Posted: 01 Aug 2014 06:12 AM PDT A 20-page supplement has been published, covering the current knowledge of anticoagulant-associated intracerebral hemorrhage (AAICH) and methods in use for management of the condition. Intracerebral hemorrhage (ICH) is a potentially deadly form of hemorrhagic stroke. A medical emergency, ICH occurs when blood escapes into brain tissue from an injured or diseased blood vessel. Increased blood in the brain builds up pressure within the skull, which can cause unconsciousness and death.

New guidelines help keep asthma out of 'yellow zone' Posted: 01 Aug 2014 06:12 AM PDT New guidelines to assist patients in recognizing and treating acute loss of asthma control. They apply to the home setting only; not providers' offices, emergency departments or hospital settings.

Female baby boomers with asthma? You may need help Posted: 01 Aug 2014 06:12 AM PDT Women over the age of 65 who have asthma, are also likely to have a range of other health-related issues which are barriers to them staying healthy. Among other things, this group of women tends to not make asthma a priority when caring for themselves, leading to other asthma-related issues.

Plastic surgeons or nurses: Who are the better injectors? Posted: 01 Aug 2014 06:12 AM PDT In recent years, minimally invasive aesthetic injectable procedures have grown in popularity as more and more men and women are seeking age-defying treatments. As Botulinum toxin -- generally known as BOTOX® -- use has increased, a growing number of nonaesthetic health professionals have emerged to perform procedures utilizing this and other injectables. According to a survey, plastic surgeons consider themselves the most capable injectors.

Common herbal-based anti-malarial drug effective in controlling asthma, study suggests Posted: 01 Aug 2014 06:11 AM PDT Asthmatic patients may soon have a more effective way to control the condition, thanks to a new pharmacological discovery.

Scientists find new calorie-burning switch in brown fat Posted: 01 Aug 2014 06:11 AM PDT Biologists have identified a signaling pathway that switches on a powerful calorie-burning process in brown fat cells. The study sheds light on a process known as "brown fat thermogenesis," which is of great interest to medical researchers because it naturally stimulates weight loss and may also protect against diabetes.

Keep calm moms: Maternal stress during pregnancy linked to asthma risk in offspring Posted: 01 Aug 2014 06:10 AM PDT During pregnancy, many women make a concerted effort to keep stress levels low -- and for good reason. Maternal stress has been linked to a number of negative outcomes for women and their infants, including developmental and behavioral problems. Now, it has been linked to the development of asthma. Researchers found that a single bout of stress during pregnancy can affect allergy and asthma susceptibility in neonates.

To combat obesity among U.S. Latina immigrants, cultural food patterns must be acknowledged Posted: 31 Jul 2014 01:00 PM PDT The factors that contribute to the problem of obesity among Latina immigrants in the U.S.A is the focus of new research. By compiling a systematic review of qualitative studies that focused on food patterns in Latina women, researchers have brought new light to this subject.

Popping pills to pushing needles: Prescription opioid abuse among young adults in NYC Posted: 31 Jul 2014 01:00 PM PDT Researchers have explored, within a social context, the drug-use and sexual experiences of young adult (ages 18-32) nonmedical prescription opioid users as they relate to risk for HIV and HCV transmission.

Childhood coxsackie virus infection depletes cardiac stem cells, might compromise heart health in adults Posted: 31 Jul 2014 11:57 AM PDT There is epidemiological evidence that links type B coxsackie virus infection with heart disease, and research now suggests a mechanism by which early infection impairs the heart's ability to tolerate stress at later stages of life. CVB infection is very common and affects mostly children, and is often asymptomatic.

Depression as a risk factor for dementia: Link is independent of dementia-related brain changes Posted: 30 Jul 2014 01:15 PM PDT A new study by neuropsychiatric researchers gives insight into the relationship between depression and dementia. The current study indicates that the association of depression with dementia is independent of dementia-related brain changes.

Target growth-driving cells within tumors, not fastest-proliferating cells Posted: 30 Jul 2014 10:31 AM PDT Growth-driving cancer cells may be better targets for therapies than cells that proliferate the fastest within the tumor, experts say. Of the many sub-groups of cells jockeying for supremacy within a cancerous tumor, the most dangerous may not be those that can proliferate the fastest, they explain in a new article.
