A research team from the Nagoya University Graduate School of Medicine has discovered a promising way to slow the progression of heart failure in mice. They fed mice a diet rich in the soybean protein, β-conglycinin (β-CG), which can support heart health by influencing gut bacteria. Their analysis revealed that the soybean protein rich diet increased the production of the short-chain fatty acids (SCFAs) in the intestine that play a role in protecting the heart. Their findings were published in Clinical Nutrition.

Many people with heart problems try to eat a nutritious diet to reduce their risk of disease. As part of a healthy diet, soybeans have long been recognized for their antioxidant and anti-inflammatory properties...

A new UC Davis Health study has uncovered how Salmonella bacteria, a major cause of food poisoning, can invade the gut even when protective bacteria are present. The research, published in the Proceedings of the National Academy of Sciences, explains how the pathogen tricks the gut environment to escape the body’s natural defenses.

The digestive system is home to trillions of bacteria, many of which produce short-chain fatty acids (SCFAs) that help fight harmful pathogens. But Salmonella manages to grow and spread in the gut, even though these protective compounds are present. The study asks: How does Salmonella get around this defense?

“We knew that Salmonella invades the small intestine, although it is not ...

Researchers at The Hospital for Sick Children (SickKids) have uncovered that stress changes how our brain encodes and retrieves aversive memories, and discovered a promising new way to restore appropriate memory specificity in people with post-traumatic stress disorder (PTSD).

If you stumble during a presentation, you might feel stressed the next time you have to present because your brain associates your next presentation with that one poor and aversive experience. This type of stress is tied to one memory.

But stress from traumatic events like violence or generalized anxiety disorder can spread far beyond the original event, known as stress-induced aversive memory generalization, where fireworks or car backfires can trigger seemingly unrelated ...

Excess cholesterol is known to form artery-clogging plaques that can lead to stroke, arterial disease, heart attack, and more, making it the focus of many heart health campaigns. Fortunately, this attention to cholesterol has prompted the development of cholesterol-lowering drugs called statins and lifestyle interventions like dietary and exercise regimens. But what if there’s more to the picture than just cholesterol?

New research from Salk Institute scientists describes how another class of lipids, called sphingolipids, contributes to arterial plaques and atherosclerotic cardiovascular disease (ASCVD)...
