The brain is uniquely protected against invading bacteria and viruses, but its defence mechanism has long remained a mystery. Now, a study in mice, confirmed in human samples, has shown that the brain has a surprising ally in its protection: the gut.

The brain is arguably the most important organ in the body, as it controls most other body systems and enables reasoning, intelligence, and emotion. Humans have evolved a variety of protective measures to prevent physical damage to the brain: it sits in a solid, bony case — the skull — and is wrapped in three layers of watertight tissue known as the meninges.

Avoiding Inflammatory foods can Lower Heart disease, Stroke risk

Dietary Inflammatory Potential and Risk of Cardiovascular Disease Among Men and Women in the U.S.

Study further examines connection between inflammation and heart disease through impact of inflammatory food consumption. Diets high in red and processed meat, refined grains and sugary beverages, which have been associated with increased inflammation in the body, can increase subsequent risk of heart disease and stroke compared to diets filled with anti-inflammatory foods according to a study published today in the Journal of the American College of Cardiology. A separate JACC study assessed the positive effects eating walnuts, an anti-inflammatory food, had on decreasing inflammation and heart disease risk.

Chronic inflammation has been shown to play an important role in the developme...

Implantable Device can Monitor and Treat Heart Disease

Yu cardiac patch
Cunjiang Yu, Bill D. Cook Associate Professor of Mechanical Engineering at UH, led a group of researchers that developed a cardiac patch made from fully rubbery electronics that can be placed directly on the heart to collect electrophysiological activity, temperature, heartbeat and other indicators, all at the same time.

Researchers reported developing a cardiac patch made from fully rubbery electronics that can be placed directly on the heart to collect electrophysiological activity, temperature, heartbeat and other indicators, all at the same time.

Pacemakers and other implantable cardiac devices used to monitor and treat arrhythmias and other heart problems have generally had one of two drawbacks — they are made with rigid materials that can’t move to accommodate a beating heart,...

Some of the principal treatments for osteoporosis, denosumab, zoledronate and calcium, could have a protective effect against COVID-19 in patients who take them, specifically a 30 to 40% reduction in the rate of infection, according to the results of a joint study by Hospital del Mar, the Hospital del Mar Medical Research Institute (IMIM), Pompeu Fabra University and the Pere Virgili Health Park. The study, the first of its kind in the world, has just been published the journal Aging.

The last author of the study, Dr...
