The physiological functions of vision, secretion and cardiac contractility are strongly dependent on sodium-calcium (Na+-Ca2+) exchange activity, according to the proceedings of the last NCX ...

Cerebral ischaemia, resulting from an interruption of blood supply to the brain, initiates a series of deleterious cellular events characterised by ionic imbalance and excitotoxicity. Central to this ...

Oregon Health & Science University research shows how calcium regulates the recharging of high-frequency auditory nerve cells after they've fired a signal burst. The study indicates calcium ions play ...

Calcium in the mitochondria -- the energy factory of cells -- may be one of the keys to understanding and treating Alzheimer's disease and dementia. Researchers have now identified how an imbalance of ...

(Philadelphia, PA) – Calcium transport into and out of mitochondria – the powerhouses of cells – is central to cellular energy production and cell death. To maintain the balance of calcium within ...

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 ...

Eight patients with alcoholic cirrhosis and ascites were studied. In 4 patients, urine was collected from 8 a.m. to 12 noon, 12 noon to 3 p.m., 3 p.m. to 6 p.m. and 6 p.m. to 8 a.m. for two successive ...
