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 ...

Unsaturated fatty acids play a role in winter hibernation

The duration of the periods for which animals hibernate in winter is affected by the quantity of unsaturated fatty acids that they absorb from their food. How animals react to an excess – or a lack – of unsaturated fatty ...

A heartbeat away? Hybrid 'patch' could replace transplants

Because heart cells cannot multiply and cardiac muscles contain few stem cells, heart tissue is unable to repair itself after a heart attack. Now Tel Aviv University researchers are literally setting a new gold standard in ...

New mouse model reveals a mystery of Duchenne muscular dystrophy

Children with Duchenne muscular dystrophy often die as young adults from heart and breathing complications. However, scientists have been puzzled for decades by the fact that laboratory mice bearing the same genetic mutation ...

How nanotechnology could keep your heart healthy

Since the heart is such a delicate and critical organ, clinicians usually opt not to intervene with the dead cells that remain after a heart attack or cardiac disease. "But we think that all heart attacks deserve some kind ...

And the beat goes on: The reliable heartbeat of hibernators

At the current temperatures, all hibernators have probably emerged from their winter hibernation and are enjoying the warm weather. However, this is quite different during the cold season. Many small mammals such as marmots, ...

Scientists identify critical enzyme in healthy heart function

Scientists are reporting the first-ever data to show that the enzyme calcineurin is critical in controlling normal development and function of heart cells, and that loss of the protein leads to heart problems and death in ...

Cardiac function curve

A cardiac function curve is a graph showing the relationship between right atrial pressure (x-axis) and cardiac output (y-axis).

Superimposition of the cardiac function curve and venous return curve is used in one hemodynamic model.
