Statin therapy produces significant reductions in major vascular events irrespective of age, including in people older than 75 years, according to a new study published in The Lancet. Statins produce significant reductions in major vascular events, but there is less direct evidence of benefit among patients older than 75 years …

An international team of researchers from the United States, Australia, Poland, Norway, and New Zealand, has found higher levels of Porphyromonas gingivalis, a bacterium associated with chronic gum disease (periodontitis), and toxic enzymes from the bacterium called gingipains in the brains of patients with Alzheimer’s disease. The team has also …

The newly-discovered ‘trans-cortical vessels’ connect the bone marrow with the periosteal circulation, according to new research published in the journal Nature Metabolism. Closed circulatory systems underlie the function of vertebrate organs, but in long bones their structure is unclear although they constitute the exit route for bone marrow leukocytes. To …

Fasting affects peripheral circadian clocks in the liver and skeletal muscle, causing them to rewire their metabolism, which can ultimately lead to improved health and protection against aging-associated diseases, according to a new study published in the journal Cell Reports. Kinouchi et al reveal that fasting affects peripheral circadian clocks …

Blood-forming (hematopoietic) adult stem cells reside deep in the bone marrow and are responsible for regenerating the body’s blood supply including red blood cells, white blood cells, and platelets. In a study published this week in the journal Cell Reports, a team of researchers from China and the United States …

According to a study published in the journal Immunity, fever alters surface proteins on immune cells to make them better able to travel via blood vessels to reach the site of infection. Fever is an evolutionarily conserved response in both endothermic and ectothermic species and confers survival benefits during infection …

An international team of researchers led by Queen’s University, Columbia University and the Federal University of Rio de Janeiro has found that irisin, a hormone released by muscles during exercise, could slow the progression of Alzheimer’s disease. Irisin is produced by muscles during exercise. Image credit: Free-Photos. “In the past …
