Heart patch could limit muscle damage in heart attack aftermath

Researchers have designed a new type of adhesive patch that can be placed directly on the heart and may one day help to reduce the stretching of heart muscle that often occurs after a heart attack. The patch, made from a water-based hydrogel material, was developed using computer simulations of heart function in order to fine tune the material’s mechanical […]

Scientists ID new metabolic target to prevent, treat heart failure at earliest stage

Researchers with The Ohio State University College of Medicine and The Ohio State University Wexner Medical Center have identified a metabolic process in the heart that, if treated, could someday prevent or slow the progression of heart failure. The American Heart Association journal Circulation published the findings today. Before any physical signs or symptoms of heart failure are present, the […]

Bad cholesterol: ‘Slim down’ fat-carrying particles to reduce its spread

The enzyme that ‘loads up’ fat-carrying particles in the liver before they are transported around the body has been identified for the first time by scientists at the University of Warwick. The discovery also reveals how to ‘slim down’ these particles to reduce the amount of the worst type of ‘bad’ cholesterol distributed throughout the body and could pave the […]

How long do people need to be monitored after fainting? Study reveals best ways to catch life-threatening conditions

For the first time, physicians in the Emergency Department (ED) have evidence-based recommendations on how best to catch the life-threatening conditions that make some people faint. New research published in Circulation suggests that low-risk patients can be safely sent home by a physician after spending two hours in the ED, and medium and high-risk patients can be sent home after […]

Hand-knitted molecules: Chemistry at very small scales

The fabrication of electronic components usually follows a top-down pathway in specialized physical laboratories. Using special carving tools in clean rooms, scientists are capable of fabricating structures reaching only a few nanometers. However, atomic precision remains very challenging and usually requires special microscopes such as an Atomic Force Microscope (AFM) or a Scanning Tunneling Microscope (STM). Chemists on the other […]

High-fat diets appear bad for blood pressure in younger males and females

There’s more evidence that a high-fat diet is bad for both younger males and females, but exactly how it’s harmful may differ between the sexes, scientists report. While they hypothesized that high-fat fare would be harder on males, they found that in just four weeks both young male and female rats experienced comparable increases in blood pressure. “You have a […]
