Scientists from QIMR Berghofer's Cardiac Bioengineering Lab have developed lab-grown, three-dimensional heart tissues known ...

Heart failure (HF) is a growing global health concern, affecting more than 64 million people worldwide. It develops when the heart can no longer pump enough blood to meet the body's demands, often due ...

Researchers using cardiac MRI have found that long-term exposure to air pollution is associated with early signs of heart ...

Researchers at Tohoku University have discovered that an oral drug called MA-5 can improve both heart and muscle problems in ...

Cardiac muscle is highly organized and contains many types of cells, including fibroblasts, smooth muscle cells, and cardiomyocytes. Cardiac muscle only develops in the heart.

In this study, we aimed to investigate the effect of gap junction (GJ) on apoptosis of smooth muscle. Forty adult male guinea pigs were randomly divided into four groups with 10 guinea pigs in each ...

Coupling between cardiac cells—An important determinant of electrical impulse propagation and arrhythmogenesis. Biophysics Reviews, 2021; 2 (3): 031301 DOI: 10.1063/5.0050192 ...

The connections between cells forming the low resistance pathway and facilitating the current flow are called gap junctions. Each consists of many channels, which are formed when specific proteins ...

Cells are connected by gap junctions, which are vital for a healthy heart. The rhythm in a working heart is regulated by electrical impulses. Disturbances of this bioelectrical process can result in ...

Rationale: Efficient communication between heart cells is vital to ensure the anisotropic propagation of electrical impulses, a function mainly accomplished by gap junctions (GJ) composed of Cx43 ...

Innexins are a family of proteins that form gap junctions in invertebrate neurons and muscle cells. Gap junctions allow free (though gated) movement of ions and small signaling molecules between the ...
