7 Early Warning Signs Of An HIV Infection
Illustration: Kim Salt for HuffPost; Photos: Getty Images Sore muscles and swollen lymph nodes could be subtle red flags. During the first few weeks of being infected with human immunodeficiency virus (HIV), most people — roughly two-thirds — experience a mix of flu-like symptoms that indicate their body is reacting to the virus. After being […]
Common Headaches May Be Pains in the Neck
CHICAGO — Inflammation and edema of the trapezius muscles appeared linked to tension and migraine headaches, a small prospective cohort study found. Patients with mixed-type tension and migraine headaches demonstrated the highest muscle T2 MRI values (31.4 ms on the right and left sides), and the average value was significantly higher compared to those with […]
Calorie restriction in humans builds strong muscle and stimulates healthy aging genes
Reducing overall calorie intake may rejuvenate your muscles and activate biological pathways important for good health, according to researchers at the National Institutes of Health and their colleagues. Decreasing calories without depriving the body of essential vitamins and minerals, known as calorie restriction, has long been known to delay the progression of age-related diseases in […]
Exercise and muscle regulation: Implications for diabetes and obesity
How do our muscles respond at the molecular level to exercise? Researchers at Helmholtz Munich and the German Institute of Human Nutrition Potsdam-Rehbrücke (DIfE) have unraveled the cellular basis and signaling pathways responsible for the positive impact of physical activity on our overall health. Regulatory T cells, a type of immune cell, play a critical […]
How fit is your gut microbiome? New research shows duration and not intensity of exercise is most important
Exercise has many benefits — strengthening muscles and bones, preventing disease and extending lifespan. It is also known to change the composition and activity of the trillions of microbes in our guts known as the microbiome. It is well known that the microbiomes of athletes are different from those who are sedentary. This is not […]
Skin: An additional tool for the versatile elephant trunk: Elephant biomechanics suggests a new approach for soft robotics
A new study from Georgia Institute of Technology suggests that an elephant’s muscles aren’t the only way it stretches its trunk — its folded skin also plays an important role. The combination of muscle and skin gives the animal the versatility to grab fragile vegetation and rip apart tree trunks. The research, in collaboration with […]
Multiple treatments to slow age-related muscle wasting
Everyone wants to stay fit and healthy as they grow old. But as we age, our body degrades, our muscles shrink and strength declines. Some older people suffer from excessive muscle loss, a condition known as sarcopenia. University of Basel researchers show that a combination therapy could delay the onset of sarcopenia. We now live […]
I Work With Dying Veterans. Here’s Why I Don’t Automatically Thank Them For Their Service.
James shifts nervously from one foot to the other, sweat glistening on his forehead and his muscles tense. A smiling intern approaches with a flag pin intent on thanking him for his military service whether he likes it or not. That’s when he bolts for the door. I take off after him; there’s no way […]
