Each year, millions of people sustain a traumatic brain injury (TBI), often resulting in serious, long-term consequences. Research indicates that even one head injury is linked to a higher risk of developing dementia, with the risk increasing further after two or more. A recent study found that TBIs can reactivate dormant herpes simplex virus type 1 (HSV-1), driving neuroinflammation and contributing to the development of Alzheimer's. Researchers created a three-dimensional model of the human brain. Then, they subjected HSV-1-infected and non-infected brain tissue to multiple blows, emulating... brain alzheimer's inflammation virus tbi
Read moreAlthough iron is essential for many physiological processes in the body, it can also be harmful, inducing oxidative stress and hindering neurogenesis. The body typically stores iron in protein complexes until needed, but these storage processes decline with age, leading to iron accumulation in body tissues. A recent study revealed that iron can build up in the brain, impairing cognitive function. Nevertheless, dietary components can help reduce iron accumulation in the brain and maintain cognitive health. Researchers examined the brain health of 72 cognitively healthy older adults by conductin... brain diet iron polyphenol
Read morePathological increases in the heart's left ventricle typically arise from diseases or unhealthy behaviors, such as increased sedentary time, and can negatively affect heart function. These changes usually manifest in adulthood and are robust predictors of cardiovascular disease-related death. Physiological increases in the left ventricle, on the other hand, are beneficial adaptations that occur in response to healthy activities, such as moderate-to-vigorous physical activity. These changes promote a stronger and more efficient heart muscle without the adverse effects associated with pathologic... exercise heart disease cardiovascular
Read moreThe pain relieving drug acetaminophen (commonly known as Tylenol or paracetamol) is considered safe for use during pregnancy by the Food and Drug Administration and European Medicines Authority; however, recent evidence suggests that acetaminophen may increase the risk of fetal neurodevelopmental (https://pubmed.ncbi.nlm.nih.gov/29341895/), reproductive, and urogenital disorders. (https://pubmed.ncbi.nlm.nih.gov/27150289/). A group of expert scientists, clinicians, and public health professionals recently issued a statement calling for greater caution in recommending acetaminophen use during p... pregnancy autism
Read moreThe gut microbiota is composed of the community of bacteria, archaea, fungi, and viruses that live in the human intestine and is unique to each individual. Diet can modulate the structure and function of the gut microbiota in ways that either increase or decrease disease risk. Findings of a new report detail the effects of a very-low-calorie diet on the gut microbiota, weight loss, and infection risk. Following the absorption of most macronutrients (carbohydrates, fats, and proteins) and micronutrients (vitamins and minerals) present in food in the small intestine, undigested food travels to t... obesity microbiome fasting antibiotics
