New evidence explains how warming-up enhances muscle performance Date: October 26, 2023 Source: Osaka University Summary: Researchers have investigated the effect of increased cell temperature on ...

According to the research, the protein seems to sense stress on the muscle cells and adjusts sarcomere shortening – and consequently, muscle contraction – based on how hard the heart needs to work. If ...

Sweet taste receptors in the heart: A new pathway for cardiac regulation New research shows that the heart can sense sweeteners and can increase the force of heart muscle contraction in response ...

Without this protein, muscle contraction occurred at a higher rate, especially when the heart was under increased stress." The study is published in the Journal of General Physiology.

But we're proposing a more direct consequence, where we have a spike in our blood sugar after eating a meal, and that's binding to these sweet taste receptors on the heart muscle cells, causing a ...

This new study is the first to identify specific “sweet taste” receptors, known as TAS1R2 and TAS1R3, on the surface of heart muscle cells. Racing heart ...

Calf muscles sit in the back of your lower legs, starting below your knee and extending to your ankle. Besides the basic movement, they are also responsible for pushing blood up towards the heart.

Moreover, while the deficiency in the ribosomal protein, known as RPL3L, altered translation dynamics for the entire tissue, its effects were most pronounced for proteins related cardiac muscle ...

In a heartbeat, cardiac muscle cells contract to push blood out to the body, then relax to allow the heart to fill again. This is possible because muscle proteins are organized into sarcomeres, which ...
