The drugmaker working to develop a pill to boost sexual desire in women says regulators are demanding more studies on the experimental drug. Sprout Pharmaceuticals said that the Food and Drug Administration wants to see more data on how the company's drug, flibanserin, interacts with other medications and how it affects driving ability. Nearly 10 percent of women studied in company trials reported sleepiness while taking the daily pill.
Curtin University researchers have found a way to breed disease-resistant wheat with no downside, potentially bringing multi-million dollar savings to Australia’s agricultural industry. According to John Curtin Distinguished Professor Richard Oliver, Director of the Australian Centre for Necrotrophic Fungal Pathogens at Curtin, farmers can lose more than 0.35 tonnes per hectare in wheat yields to Yellow Spot, even after applying fungicide.
Researchers have found that the melanopsin pigment in the eye is potentially more sensitive to light than its more famous counterpart, rhodopsin, the pigment that allows for night vision. Recent studies revealed the existence of a small number of intrinsically photosensitive nervous cells that regulate non-visual light responses.
Some of the world's biggest drugmakers are playing a larger role in anti-doping efforts at this year's Winter Olympics: They're providing information on drugs that once would have been considered proprietary trade secrets. GlaxoSmithKline, Amgen, and Roche are among the drugmakers that have begun sharing "confidential research and data" with anti-doping officials about experimental drugs they are developing.
In an attempt to learn how and why certain cancers spread to specific organs, researchers have developed a three-dimensional microfluidic platform that mimics the spread of breast cancer cells into a bonelike environment.
Testing for HGH, including samples from Sochi Olympic athletes, should resume after being stalled by an appeal case ruling last year, WADA director-general David Howman said. WADA also said it was "totally outrageous" that a Russian scientist reportedly offered to sell a potent and undetectable new muscle-building drug to undercover journalists. The substance, known as full size MGF, has only been trialed on animals.
Declines in the underlying brain skills needed to think, remember, and learn are normal in aging. Therapies to improve the cognitive health of older adults are critically important for lessening declines in mental performance as people age.
Scientists have for the first time sequenced an ancient RNA genome—of a barley virus once believed to be only 150 years old— pushing its origin back at least 2,000 years and revealing how intense farming at the time of the Crusades contributed to its spread.
Monkeys that ate a diet rich in omega-3 fatty acids had brains with highly connected and well organized neural networks—in some ways akin to the neural networks in healthy humans—while monkeys that ate a diet deficient in the fatty acids had much more limited brain networking.
In his 2014 State of the Union address, President Obama referred to an August 2013 CDC study that showed a decline in the obesity rate among low-income preschool children. While the CDC report’s data is encouraging, a new study published by University of Illinois kinesiology and community health professor Ruopeng An shows the notion that the American obesity epidemic has begun to reverse may be premature.
University of Adelaide researchers have identified a key step for the future prevention of liver failure resulting from taking too much of the everyday painkiller paracetamol (also known as acetaminophen). The study pinpoints a target for new treatments to prevent the potentially lethal consequences of paracetamol overdose.
CVS Caremark is kicking the habit of selling tobacco products at its more than 7,600 drugstores nationwide as it focuses more on providing health care. The nation's second-largest drugstore chain said Wednesday that it will phase out cigarettes, cigars and chewing tobacco by Oct. 1, a move that will cost about $2 billion in annual revenue.
Designing nanomedicine to combat diseases is a hot area of scientific research, primarily for treating cancer, but very little is known in the context of atherosclerotic disease. Scientists have engineered a microchip coated with blood vessel cells to learn more about the conditions under which nanoparticles accumulate in the plaque-filled arteries of patients with atherosclerosis.
Gasoline-like fuels can be made from cellulosic materials such as farm and forestry waste using a new process invented by chemists at the University of California, Davis. The process could open up new markets for plant-based fuels, beyond existing diesel substitutes.
Adoption of new guidelines recommending screening mammography every two years for women ages 50 to 74 would result in breast cancer screening that is equally effective, while saving the United States $4.3 billion a year in health care costs, according to a study led by UC San Francisco.
Children newly diagnosed with Crohn’s disease may benefit from early treatment with the biologic drugs known as anti-TNF-α agents. Researchers compared the effectiveness of early (within three months after diagnosis) treatment with anti-TNF-α inhibitors, compared with early treatment with immunomodulatory drugs, in attaining clinical remission and facilitating growth in children with Crohn's disease.
Could too much sugar be deadly? The biggest study of its kind suggests the answer is yes, at least when it comes to fatal heart problems. It doesn't take all that much extra sugar, hidden in many processed foods, to substantially raise the risk, the researchers found, and most Americans eat more than the safest amount.
In a study to be presented on Feb. 6 at 3 p.m. CST, at the Society for Maternal-Fetal Medicine’s annual meeting, The Pregnancy Meeting, in New Orleans, researchers will report that women ages 35 and older are at a decreased risk of having a child with a major congenital malformation, after excluding chromosomal abnormalities.
An experimental therapy that fed children with peanut allergies small amounts of peanut flour has helped more than 80 percent of them safely eat a handful of the previously worrisome nuts. Although experts say the results of the carefully monitored study are encouraging, they warn it isn't something that parents should try at home.
Those efforts to fight obesity in schools? Think younger. A new study finds that much of a child's "weight fate" is set by age 5, and that nearly half of kids who became obese by the eighth grade were already overweight when they started kindergarten.
The regular appearance of food poisoning in the news, including a recent event that led to the recall of more than 33,000 pounds of chicken, drives home the need for better bacterial detection long before meats and produce make it to the dinner table. On the horizon is a new approach for pathogen screening that is far faster than current commercial methods.
An international team of scientists has discovered that two of the world’s most devastating plagues – the plague of Justinian and the Black Death, each responsible for killing as many as half the people in Europe—were caused by distinct strains of the same pathogen, one that faded out on its own, the other leading to worldwide spread and re-emergence in the late 1800s.
A team of researchers has discovered a protein that is required for the growth of tiny, but critical, hair-like structures called cilia on cell surfaces. The discovery has important implications for human health because lack of cilia can lead to serious diseases such as polycystic kidney disease, blindness, and neurological disorders.
Your best friend swears by the Paleo Diet. Your boss loves Atkins. Your sister is gluten-free, and your roommate is an acolyte of Michael Pollan. So who’s right? Maybe they all are. Researchers identified a collection of genes that allow an organism to adapt to different diets and showed that without the genes, even minor tweaks to diets can cause premature aging and death.
After 20 years, the nutrition facts label on the back of food packages is getting a makeover. Knowledge about nutrition has evolved since the early 1990s, and the Food and Drug Administration says the labels need to reflect that. Nutritionists and other health experts have their own wish list for label changes.
