Calcium is a very special nutrient. In the cells of most living beings calcium ions function as so-called second messengers to transmit important signals. The same applies equally to animal, plant and ...

Calcium ions enable cells to communicate with one another, allowing neurons to interact, muscles to contract, and the heart's muscle cells to synchronize and beat. To better understand these processes ...

Researchers at the Intermountain Medical Center Heart Institute in Salt Lake City have found that incorporating underused, but available, imaging technologies more precisely predicts who's at risk for ...

MRI scans can look deep into the brain using powerful magnets to see brain anatomy and structure. Different types of MRI scans including functional MRIs that track blood flow as an indicator of brain ...

Calcium ions are essential for cells, but can be toxic in higher concentrations. A team of researchers has now designed and prepared a combination drug that kills tumor cells by modulating the calcium ...

Alzheimer's disease (AD) is the most common cause of dementia but the changes in brain cell function underlying memory loss remains poorly understood. Researchers at the University of Bristol have ...

The ability to modify the intracellular concentrations of divalent calcium ions is vital to normal cell functioning. In the cells of the cardiac muscle, calcium ions play a crucial role in coupling ...
