Regardless of age, adults are advised to do at least 150 minutes a week of moderate intensity activity or 75 minutes a week of vigorous intensity activity, or an equivalent combination. “Our study suggests that walking at least one hour every week is beneficial for people aged 85 years and older. Put simply, walk for […]
A research team led by the University of Michigan Health Department of Neurology followed more than 120 patients who underwent bariatric surgery for obesity over two years after the procedure. They found that all metabolic risk factors for developing diabetes, such as high glucose and lipid levels, improved outside of blood pressure and total cholesterol. […]
Scientists at the Medical College of Georgia looked in the hypothalamus, key to functions like releasing hormones and regulating hunger, thirst, mood, sex drive and sleep, at a population of neurons called the proopiomelanocortin, or POMC, neurons, in response to 10 days of chronic, unpredictable stress. They found the stressors increased spontaneous firing of these […]
Post-traumatic stress disorder in U.S. military members frequently follows a concussion-like brain injury. “Is one causing the other, and how does that occur?” asked senior author Michael Fanselow. Two groups of rats were studied. Through surgery, a concussion-like brain injury was produced in 19 of the rats. Sixteen other rats also had the surgery, but […]
Knee joint injuries are typically related to sports, but people often do not know that such injuries may lead to joint inflammation and post-traumatic osteoarthritis. The study presents a new mechanobiological model for cartilage degeneration by implementing tissue deformation and fluid flow as mechanisms for cartilage breakdown when a normal dynamic loading, such as walking, […]
Fermented foods are a source of tryptophan, an amino acid key to the production of serotonin, a messenger in the brain which influences several aspects of brain function, including mood. The foods may also contain other brain messengers in their raw form. Researchers at APC Microbiome, University College Cork, and Teagasc are currently working on […]
A new study from UCLA researchers finds sex-specific brain signals that appear to confirm that different drivers lead men and women to develop obesity. “We found differences in several of the brain’s networks associated with early life adversity, mental health quality, and the way sensory stimulation is experienced. The resulting brain signatures, based on multimodal […]
Prostate cancer is the second-leading cause of cancer death among men in the United States; about 33,330 men are expected to die of the disease this year. Most prostate cancers remain confined to the prostate and can be successfully managed by active surveillance or local therapy, with five-year survival rates above 99%. But once prostate […]
Researchers at the University of Maryland School of Medicine have conducted a study that has determined the role that a critical protein plays in the development of hair cells. Hearing relies on the proper functioning of specialized cells within the inner ear called hair cells. Researchers have been focusing on describing the developmental steps that […]
Hair follicles are mini-organs from which new hair constantly grows. The basis for new hair growth is the proper function of hair follicle stem cells (HFSCs). HFSCs undergo cyclic symmetric and asymmetric cell divisions (SCDs and ACDs). SCDs generate two identical cells that go on to have the same fate, while ACDs generate a differentiating […]
