More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
Even small tumors can be aggressive, according to a study in patients with early stage breast cancer presented at the ESMO 2017 Congress in Madrid. They found that nearly one in four small tumors were aggressive and patients benefited from chemotherapy. Aggressive tumors could be identified by a 70-gene signature.
The dominant Australian community would very much like to keep Indigenous communities from alcohol, but indigenous communities aren't having it. A giant black market has sprung up and such non-government alcohol sells for up to 1100 percent of the retail price.
The Centers for Disease Control and Prevention seem more scared than elated by United States smoking rates. They have migrated from a war on the world's top killer, smoking, to being in a war on a chemical, nicotine.They needn't be concerned. Science and health have won, and it wasn't because of taxes on cigarettes or a cottage industry of anti-smoking ads built by a tobacco company settlement, it was because of peer pressure. In young people. As the American Council on Science and Health, a pro-science consumer advocacy group based in New York City, has said since the 1970s, smoking is a pediatric disease. In the past, 90 percent of smokers picked up the habit by age 18, making adolescence a critical time for smoking-prevention efforts.
Center for Science in the Public Interest, a litigation group that sues food companies, may be dusting off some of its old materials after new report which finds "good" cholesterol, also known as HDL, might not be as good as we think.
The new paper contradicts findings from the last 25 years that high levels of HDL in the blood are a good thing. They instead found that people with extremely high levels of good cholesterol have a higher mortality rate than people with normal levels. For men with extremely high levels, the mortality rate was 106 percent higher than for the normal group.
Researchers looked at frequency magnetic resonance imaging (fMRI) images to compare neural responses to food cues in overweight and normal weight adolescents.
They noted that food stimuli activated regions of the brain associated with reward and emotion in all groups but overweight adolescents had progressively less neural activity in circuits of the brain that support self-regulation and attention.
If mouse studies were transferable to humans, we'd have cured every disease thousands of times. That is the big reason why you shouldn't accept scaremongering about the chemical of the week in the New York Times, or claims about Miracle Vegetables in the Washington Post.
Licorice roots have a diverse history, having been used throughout history as a flavoring agent and as an ingredient in some licorice candies, while in ancient Egyptian times it was a tea and the Chinese used it for medicinal purposes.
One trend in the alternative medicine movement, which seeks to replace approved pharmacology with essentially untested natural products (as long as they carry a disclaimer FDA has not verified their efficacy or safety), is for women to take licorice extracts as supplements to treat hot flashes and other menopausal symptoms.
Survey results show that workers believe the American workplace is physically and emotionally taxing, and they don't like the social environment. Since we are only now recovering from an economic malaise, they also worry about unstable work schedules. Some cited unpleasant and potentially hazardous working conditions.
Physicists from the ATLAS experiment at CERN have confirmed one of the oldest predictions of quantum electrodynamics (QED), finding the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction.
Nomophobia, defined as smartphone separation anxiety, is when people perceive smartphones as part of their extended selves.Counselors, lawyers and therapists are aggressively pushing it as the fad diagnosis of 2017, but what behaviors and descriptors can help identify people with high nomophobia ? A new paper compares how people considered to have high and low nomophobic tendencies perceive and value their smartphones.
Cancer is a leading cause of illness and death worldwide. In 2015, the World Health Organisation (WHO) recorded 8.8 million cancer-related deaths and nearly twice that are diagnosed each year. Since people are living longer, cancer diagnoses is likely to continue to increase by about 70% for at least the next two decades.Given that more cancers are likely in the developing world, the search is on for treatments that are simple and inexpensive to manufacture. The answer may lie in herbal medicine. The problem, as always, is that while there are numerous anecdotes about those, there are few studies.
Just like some people are overweight but healthy - an obesity paradox - some people are thin but have a three-fold higher risk of mortality and/or cardiovascular events. Weight is not the best way to understand metabolic health, according to an analysis of lean, overweight and obese people.A new paper claims that ~20 percent of normal weight adults are still metabolically unhealthy and have a higher risk of mortality and/or cardiovascular events than metabolically healthy obese subjects. Oddly, a reduced accumulation of fat in the lower body puts lean people at risk.One size does not fit all
