Study explores effects of occupational, lifestyle risk factors on nurses' health

Fri, 08/18/2017 - 06:23
A prospective study of more than 20,000 nurses aged 20-45 years, 88% of whom had worked night shifts, reported their most common health issues, disease history, reproductive experiences, occupational exposures, and other lifestyle- and work-related factors.

Drug-like molecule appears to interfere with inflammatory response in variety of diseases

Fri, 08/18/2017 - 06:12
A drug-like molecule developed by Duke Health researchers appears to intercede in an inflammatory response that is at the center of a variety of diseases, including some cancers, rheumatoid arthritis and Crohn's disease.

New ultra lightweight device for neural recording in mice could transform brain disorder research

Fri, 08/18/2017 - 06:00
Research published this week in Scientific Reports describes a new ultra lightweight system for recording neural activity in the brains of mice.

High-definition eye scan could reveal crucial warning signs of Alzheimer's disease

Fri, 08/18/2017 - 05:35
Cedars-Sinai neuroscience investigators have found that Alzheimer's disease affects the retina – the back of the eye – similarly to the way it affects the brain.

UAB awarded $2.2 million NIH grant to address driving attention issues

Fri, 08/18/2017 - 05:31
The Translational Research for Injury Prevention Laboratory at the University of Alabama at Birmingham has been awarded $2.2 million by the National Institutes of Health to address a major health issue.

Researchers get closer to creating new blood test that can identify breast cancer brain metastasis

Fri, 08/18/2017 - 04:44
Houston Methodist cancer researchers are now closer to creating a blood test that can identify breast cancer patients who are at increased risk for developing brain metastasis, and also monitor disease progression and response to therapy in real time.

NIH researchers unravel how male, female mouse embryos acquire sex-specific reproductive systems

Fri, 08/18/2017 - 04:28
A protein called COUP-TFII determines whether a mouse embryo develops a male reproductive tract, according to researchers at the National Institutes of Health and their colleagues at Baylor College of Medicine, Houston.

Antibiotic use makes immune cells less effective in fighting infections

Fri, 08/18/2017 - 04:18
Adding another reason for doctors to avoid the overuse of antibiotics, new research shows that a reduction in the variety of microbes in the gut interferes with the immune system's ability to fight off disease.

Study shows feasibility of noninvasive retinal imaging for screening people at risk of AD

Fri, 08/18/2017 - 04:10
Alzheimer's disease (AD) represents the leading cause of dementia worldwide. Currently, challenges in making an early and definitive diagnosis of AD limit opportunities to intervene with disease-modifying therapies before substantial neurodegeneration occurs.

Abnormal eating schedules affect skin’s protection from harmful UV rays of the sun

Fri, 08/18/2017 - 04:06
Sunbathers may want to avoid midnight snacks before catching some rays. A study in mice from the O'Donnell Brain Institute and UC Irvine shows that eating at abnormal times disrupts the biological clock of the skin, including the daytime potency of an enzyme that protects against the sun's harmful ultraviolet radiation.

Early surgery for rotator cuff tears leads to lasting improvement in outcomes

Fri, 08/18/2017 - 03:54
Early surgery to repair tears of one of the shoulder rotator cuff muscles provides lasting improvement in strength, function, and other outcomes, reports a study in the August 16, 2017 issue of The Journal of Bone & Joint Surgery. The journal is published in partnership with Wolters Kluwer.

Study explores link between socioeconomic factors and CAD in patients undergoing coronary angiography

Fri, 08/18/2017 - 03:50
Historically, from the 1930's to the 1950's, the rate of cardiovascular disease in high-income countries was high. Since the mid-1970's, the rate of cardiovascular disease has declined in high income countries, possibly due to socioeconomic inequalities and better management of risk factors for coronary heart disease among the wealthy.

Teenagers’ impulsive and risk taking behavior not related to brain deficit symptoms

Fri, 08/18/2017 - 00:23
A popular theory in recent neuroscience proposes that slow development of the prefrontal cortex - and its weak connectivity with brain reward regions - explains teenagers' seemingly impulsive and risky behavior.

Women’s decision-making habits combined with values impact choice of breast cancer treatment

Fri, 08/18/2017 - 00:11
A new study finds that more than half of women with early stage breast cancer considered an aggressive type of surgery to remove both breasts.

Thu, 08/17/2017 - 23:57
Scientists are increasingly appreciating estrogen's role in brain health. Now for the first time, production of estrogen in the brain has been directly linked to the presence of docosahexaenoic acid (DHA).

New terahertz imaging could be useful tool for detecting early-stage skin cancer

Thu, 08/17/2017 - 23:28
Researchers have developed a new terahertz imaging approach that, for the first time, can acquire micron-scale resolution images while retaining computational approaches designed to speed up image acquisition.
