Team determines how cholesterol moves inside cells

Researchers have found that high-density lipoprotein, or HDL, sometimes referred to as "good" cholesterol, is transported from the outer wall to the interior of cells by a protein that helps create a "bridge" between the ...

New study uncovers the interaction of calcium channels

Korean researchers have identified the interactions of the combinants among calcium channel proteins that exist in nerve and heart cells. The result opened a new path of developing treatments for high blood pressure and brain ...

Keeping our cells stable: A closer look at microtubules

Microtubules help to regulate cell structure. A group of Japanese researchers have used cryo-electron microscopy to shed light on how a certain protein keeps microtubules stable and regulates microtubule-based transport within ...

A self-powered heart monitor taped to the skin

Scientists have developed a human-friendly, ultra-flexible organic sensor powered by sunlight, which acts as a self-powered heart monitor. Previously, they developed a flexible photovoltaic cell that could be incorporated ...

A 3-D model of a human heart ventricle

Harvard University researchers have bioengineered a three-dimensional model of a human left heart ventricle that could be used to study diseases, test drugs and develop patient-specific treatments for heart conditions such ...

High vinculin levels help keep aging fruit fly hearts young

Our cells tend to lose their shape as we grow older, contributing to many of the effects we experience as aging. This poses particular problems for the heart, where aging can disrupt the protein network within muscle cells ...

Researchers operate lab-grown heart cells by remote control

Researchers at University of California San Diego School of Medicine and their collaborators have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command—simply by ...

First successful ablation of a cardiac arrhythmia in a horse

The Equine Cardioteam, led by Prof Gunther van Loon, has treated a Norwegian showjumper stallion with a cardiac arrhythmia by ablation. The horse had been successfully treated by electroshock therapy several times but showed ...
