The simple act of breathing is among the most familiar ways we convert nutrients to energy – inhaling molecules of oxygen and harmlessly breathing out unwanted material. But when our usual disposal mechanisms fail, the accumulated electrons can produce the kind of toxic event that causes many diseases, including cancer. […]

High blood pressure appears to accelerate a decline in cognitive performance in middle-aged and older adults, according to new research published today in Hypertension, an American Heart Association journal. Nearly half of American adults have high blood pressure or hypertension. Having high blood pressure is a risk factor for cognitive […]

A Washington state woman is recovering after a landmark organ transplant that she hopes will end her nearly decade-long bout with cancer. Kris Anderson, 51, of Redmond, received a lobe of liver from her daughter Lauren, 26, on Dec. 8. It was the Pacific Northwest’s first living-donor liver transplant for metastatic colorectal […]

Resveratrol and derived molecules were for a time excessively hyped as a means to trigger some of the beneficial metabolic response produced by calorie restriction, by acting on sirtuins, and thus have a positive impact on aging. The company Sirtris was founded to develop this area of research into a […]

Senolytic drugs are those capable of selectively destroying senescent cells. A range of such therapies are at various stages of development, including those that have reached initial human clinical trials. Senescent cell accumulation is an important cause of degenerative aging, and the removal of such cells via senolytic treatments has […]

Axin is a VIP – a Very Important Protein. It’s essential to the development of an embryo. It’s a key player in allowing the body’s cells to divide without going haywire and forming a tumour. It regulates the body’s production of lipids, or fats, which can affect aging. Essentially, it […]

The introduction of computer simulation to the identification of symptoms in children with attention-deficit/hyperactivity disorder (ADHD) has potential to provide an additional objective tool to gauge the presence and severity of behavioural problems, Ohio State University researchers suggest in a new publication. Most mental health disorders are diagnosed and treated based […]

In an in-depth study of how COVID-19 affects a patient’s brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease. In addition, they saw no signs of SARS-CoV-2 in […]

Experiments with mice and humans showed that exercise training increased the expression in adipose tissue of a key enzyme for the organism's metabolic health, combating the harmful effects of aging and obesity. Adipose tissue is not just a simple reservoir of energy for periods of food scarcity. It contributes significantly […]

Women awaiting liver transplants in the United States are known to be about one-third more likely than men to become too ill to undergo surgery or die before receiving a liver. Now a study headed by UC San Francisco and Columbia University highlights the role that frailty plays in this […]

The human body is filled with friendly bacteria. However, some of these microorganisms, such as Veillonella parvula, may be too nice. These peaceful bacteria engage in a one-sided relationship with pathogen Porphyromonas gingivalis, helping the germ multiply and cause gum disease, according to a new University at Buffalo-led study. The […]

Small studies have suggested that a group of medications called RAS inhibitors may be harmful in persons with advanced chronic kidney disease, and physicians therefore often stop the treatment in such patients. Researchers at Karolinska Institutet now show that although stopping the treatment is linked to a lower risk of […]
