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.
Eating too much meat is considered a risk factor for high cholesterol, which is a risk factor for hypertension, which is a risk factor for heart disease. Given all that statistical correlation, it's no wonder the public don't know what to believe about red meat.But white meat is no better. This is a relief for cattle ranchers, who have been subjected to decades of claims that white meat is healthier and red meat causes heart attacks. The controversial French statistical group International Agency for Research on Cancer (IARC) even lists red meat as one of its hundreds and hundreds of things they can statistically correlate to cancer, albeit in doses up to 10,000 times normal levels.
Don't drink 25 cups of coffee a day, you shouldn't consumer anything equivalent to 25 cups per day, but if you do it won't be your arteries that give out, according to research presented today at the British Cardiovascular Society (BCS) Conference in Manchester.
The U.S. Food and Drug Administration is expressing concern supplements containing vinpocetine, a supplement (e.g. Vinca minor extract, lesser periwinkle extract, common periwinkle extract) which is a derivative of the vinca alkaloid vincamine, an extract from the lesser periwinkle plant and which sellers claims will enhance memory, focus, or mental acuity, increase energy, and cause weight loss.
A new paper says that racist experiences increase inflammation in African American individuals, raising their risk of chronic illness and providing more evidence that creates physical health outcomes, states a paper led by April Thames, Ph.D., associate professor at the University of Southern California Dornsife College of Letters, Arts and Sciences."I looked at it as a chronic stressor. Our results showed that racial discrimination appears to trigger an inflammatory response among African Americans at the cellular level," states Thames.
Cancer starts as a single rogue cell whose mutations then trigger aggressive growth, damaging the health of the organism. But if cancer cells were accumulating harmful mutations faster than they could be purged, wouldn't the population eventually die out? How do cancer cells avoid complete genetic meltdown? To try and find answers, researchers in a recent study probed the most famous cultured cancer cells, HeLa cells, isolated from cervical cancer victim Henrietta Lacks in 1951 and becoming the first immortalized cell line.
Some will say that walking a dog is a conversation starter and the fitness benefits of walking are well-known, but most who walk their dog simply enjoy it, not because of health or social benefits.Using 26 interviews combined with personal written reflections of dog walking experiences, the authors of a
International Journal of Environmental Research and Public Health
paper found that while owners may say the reason they go walking is to benefit the dog, the importance of their own improved happiness and wellbeing is clear.
Though some diet book authors want to suggest certain food types have magical power - trans fats, non-nutritive sweeteners, corn syrup, sugar, etc. - the rise in type 2 diabetes does not have anything to do with soda and everything to do with energy balance.People who eat more calories than they burn on a consistent basis gain weight, and that eventually begins to hinder insulin production, which can mean type 2 diabetes.
In a recent paper, Lehigh University anthropologist Professor Allison Mickel says archaeological excavations are often led by foreigners from the West while dependent on the labor of people from the local community, a relic of Western colonial and imperial pursuits.
People treated in hospitals and other health care settings are increasingly at risk of infection with multidrug-resistant bacteria. Many of these microbes produce enzymes called extended-spectrum β-lactamases (ESBLs), which make them resistant to antibiotics. Understanding how ESBL bacteria spread from person to person is key to developing effective prevention strategies.An observational study conducted in a French hospital showed that human contact was responsible for 90 percent of the spread of one species of antibiotic-resistant bacteria to new patients, but less than 60 percent of the spread of a different species.
If you survey educators and students, current or former, many will claim they have a learning style - such as visual, auditory or tactile - that they were born with, and some say it predicts both academic and career success. There is no scientific evidence to support this common myth, according to new researc, but surveys in the United States and other industrialized countries across the world have shown that 80% to 95% of people believe in learning styles. It's difficult to say how that myth became so widespread.
A prototypical extrovert is someone talkative, outgoing, who prefers taking the initiative in groups, expresses positive emotion and enjoys seeking out new experiences. By contrast, a prototypical introvert is quiet, emotionally reserved, less effusive, and harder to get to know.You can imagine which of those is going to have an easier time in most jobs.
Ancestors of modern humans "recycled" broken flint tools 400,000 years ago in order to create small, sharp utensils with specific functions in the processing of animal products and plant materials. The results were found in digs at Qesem Cave, located just outside Tel Aviv, which was discovered in 2000 during a road construction project and has since provided insights into life in the region hundreds of thousands of years ago.
