Tea benefits: A cuppa a day can boost immune system

People who are overweight or eat a high-fat diet are the most likely to benefit. Tea has long been linked to good health. But earlier this year a study confirmed it lowers cholesterol and blood pressure – key risk factors for heart disease and stroke – while another showed it protects…

Drinking tea improves brain health, study suggests

A recent study led by researchers from the National University of Singapore (NUS) revealed that regular tea drinkers have better organised brain regions — and this is associated with healthy cognitive function — compared to non-tea drinkers. The research team made this discovery after examining neuroimaging data of 36 older…

Promising approach to reducing plaque in arteries

In a new Yale-led study, investigators have revealed previously unknown factors that contribute to the hardening of arteries and plaque growth, which cause heart disease. Their insight is the basis for a promising therapeutic approach to halt and potentially reverse plaque buildup and the progression of disease, the researchers said….

Keeping livestock in the yard just might help your baby’s immune system: Amish babies’ gut microbes lead to more robust immune development in newborn pigs

Getting up close — and a little dirty — with farm animals just might help us fend off illness, say researchers who’ve further demonstrated the benefits of early exposure to a wide variety of environmental bacteria. Scientists from The Ohio State University found that bacteria and other microbes from rural…

An ‘EpiPen’ for spinal cord injuries

An injection of nanoparticles can prevent the body’s immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis. The approach was demonstrated in mice at the University of Michigan, with the nanoparticles enhancing healing by reprogramming the aggressive immune cells — call it an…

Tumor mutations may predict response to immunotherapy

Checkpoint inhibitor drugs that stimulate the immune system have become a growing success story in the treatment of some cancers. But about half of patients whose tumors are marked by a large number of mutations from so-called mismatch repair genetic deficiency fail to respond to the drugs. Now, researchers from…

Pericytes may improve muscle recovery: Pericyte transplantation may improve skeletal muscle recovery following limb immobilization, animal study shows

Extended periods of limb immobilization — whether from long-term bed rest, casting, spaceflight, or other circumstances — can reduce skeletal muscle mass and strength to the extent that recovery is delayed or never achieved. The biological basis for this lack of recovery, however, remains unclear. An animal study published in…
