Female athletes and women who have eating disorders are prone to developing a condition called hypothalamic amenorrhea that causes them to stop menstruating. The Endocrine Society today issued a Clinical Practice Guideline advising healthcare providers on ways to diagnose and treat this condition.
A study in Neurology suggests that analyzing levels of the protein p75ECD in urine samples from people with amyotrophic lateral sclerosis (ALS) may help monitor disease progression as well as determine the effectiveness of therapies. The study was supported by National Institute of Neurological Disorders and Stroke (NINDS) and National Center for Advancing Translational Sciences (NCATS), both part of the National Institutes of Health.
Two landmark publications with co-authors from the University of Cincinnati Gardner Neuroscience Institute outline a transformative approach to defining, studying and treating Parkinson's disease. Rather than approaching Parkinson's disease as a single entity, the international cadre of researchers advocates targeting therapies to distinct 'nodes or clusters' of patients based on specific symptoms or molecular features of their disease.
Words and experience matter to surrogates making end-of-life decisions.
Heroin use is associated with excessive histone acetylation, an epigenetic process that regulates gene expression, and more years of drug use correlate with higher levels of hyperacetylation, according to research conducted at The Icahn School of Medicine at Mount Sinai and published in the journal Biological Psychiatry.
Osteoporosis affects more than 200 million people worldwide and is a serious public health concern, according to the National Osteoporosis Foundation. Now, Pamela Hinton, associate professor in the Department of Nutrition and Exercise Physiology, has published the first study in men to show that long-term, weight-bearing exercises decrease sclerostin, a protein made in the bone, and increase IGF-1, a hormone associated with bone growth. These changes promote bone formation, increasing bone density.
Nearly 1,000 feet below the bed of the Dead Sea, scientists have found evidence that during past warm periods, the Mideast has suffered drought on scales never recorded by humans -- a possible warning for current times. Thick layers of crystalline salt show that rainfall plummeted to as little as a fifth of modern levels some 120,000 years ago, and again about 10,000 years ago.
Researchers have developed a technique that uses light to get flat, plastic sheets to curve into spheres, tubes or bowls.
Are powerful, well-to-do people more charitable? It depends. According to a new study in the Journal of Consumer Research, wealthier people are more likely to donate to charity if they endorse social inequality while less wealthy people are more likely to make donations if they endorse greater equality.
The Arctic sea ice maximum extent and Antarctic minimum extent are both record lows this year. Combined, sea ice numbers are at their lowest point since satellites began to continuously measure sea ice in 1979.
The common assumption about retail therapy is that it's all about indulging in things like pricey designer duds or the latest gadgets. But according to a new study in the Journal of Consumer Research, consumers are actually more likely to make practical purchases than splurge on luxury items when they feel less in control.
Researchers from Tufts University and the University of Maryland, Baltimore County used machine learning on the Stampede supercomputer to model the cellular control network that determines how tadpoles develop. Using that model, they reverse-engineered a drug intervention that created tadpoles with a form of mixed pigmentation never before seen in nature. They plan to use the method for cancer therapies and regenerative medicine.
Dartmouth researchers unlock the key to transforming microscopic nanorings into smart materials that perform work at human-scale.
Why do people pay for experiences deliberately marketed as painful? According to a new study in the Journal of Consumer Research, consumers will pay big money for extraordinary -- even painful -- experiences to offset the physical malaise resulting from today's sedentary lifestyles.
Popular media mirror Western culture's fixation with being thin. According to a new study in the Journal of Consumer Research, even subtle reminders of idealized bodies can encourage overweight consumers to overspend.
Long gone are the days when a life of material excess and endless leisure time signified prestige. According to a new study in the Journal of Consumer Research, Americans increasingly perceive busy and overworked people as having high status.
Only case series without informative value are available for most indications. A plausible mode of action is insufficient to attribute a potential.
IQWiG has attributed a potential for a benefit to a new treatment method according to §137e SGB V. A testing study has been initiated. Numerous other assessments had no consequences.
Solar cells and photodetectors could soon be made from new types of materials based on semiconductor quantum dots, thanks to new insights based on ultrafast measurements capturing real-time photoconversion processes.
New light has been shed on the functioning of human gut bacteria which could help to develop medicines in the future to improve health and well-being.
