Study reveals new way to increase population of intestinal stem cells

Cells that line the intestinal tract are replaced every few days, a high rate of turnover that relies on a healthy population of intestinal stem cells. MIT and University of Tokyo biologists have now found that aging takes a toll on intestinal stem cells and may contribute to increased susceptibility to disorders of the gastrointestinal tract.

Preoperative donor muscle training expedites rehabilitation process in patients

Researchers at the Institute of Cognitive Neuroscience of the Higher School of Economics have proposed to train transplanted muscles in advance with new movements so that the brain can learn to use them more quickly after autotransplantation.

New medication increases muscle and bone mass in mice

It is common knowledge that as people grow older they lose a large part of their muscle mass - and neither are their bones what they once were. Researchers from Aarhus University, Denmark, working together with researchers at Erasmus Medical Center in Rotterdam have now studied a new group of medication which could prove beneficial for the elderly and the chronically ill who suffer a loss of bone- and muscle mass.

New computer program predicts risk of life-threatening arrhythmias

Combining a wealth of information derived from previous studies with data from more than 500 patients, an international team led by researchers from Johns Hopkins has developed a computer-based set of rules that more accurately predicts when patients with a rare heart condition might benefit--or not--from lifesaving implanted defibrillators.

Researchers discover underlying cause of hereditary muscle disease

Researchers at Karolinska Institutet have discovered the underlying cause of a hereditary muscle disease first characterised in a Swedish family in 1980. It proves to be the first identified disease caused by defective myoglobin, the protein that transports oxygen in muscle cells.

Sitting for long durations linked to premature deaths

A new study has found that thousands of premature deaths are occurring in the UK due to the long hours people spend sitting down. The study results were published in the latest issue of the Journal of Epidemiology and Community Health.

Causes of diabetes decline or disappear when ‘zombie cells’ are removed, shows study

Mayo Clinic researchers and their collaborators have shown that when senescent cells -- also known as "zombie cells" -- are removed from fat tissue in obese mice, severity of diabetes and a range of its causes or consequences decline or disappear. The findings appear in Aging Cell.

Nervous system relies on guidance cues for neuronal axons to reach destinations

Similar to the dozens of Sherpas that guide hikers up treacherous Himalayan mountains to reach a summit, the nervous system relies on elaborate timing and location of guidance cues for neuronal axons--threadlike projections--to successfully reach their destinations in the body.

Boys with obesity enter puberty at earlier age, shows study

Girls are not the only ones who go through puberty early if they have obesity. Boys with obesity enter puberty at an earlier age than average, according to a study that will be presented Sunday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

High-fat, high-sugar diet in mouse mothers causes problems in the hearts of offspring

A diet high in fats and sugars is known for its unhealthy effects on the heart. Scientists now have found that a high-fat, high-sugar diet in mouse mothers before and during pregnancy causes problems in the hearts of their offspring, and that such problems are passed down at least three generations, even if the younger generations only eat a standard mouse chow diet.
