GTP and Ca2+ Modulate the Inositol 1,4,5-Trisphosphate-Dependent Ca2+ Release in Streptolysin O-Permeabilized Bovine Adrenal Chromaffin Cells [PDF]
The inositol 1,4,5-trisphosphate (IP3)-induced Ca2+ release was studied using streptolysin O-permeabilized bovine adrenal chromaffin cells. The IP3-induced Ca2+ release was followed by Ca2+ reuptake into intracellular compartments.

Sediment metals adhering to biochar enhanced phosphorus adsorption in sediment capping
Metal ions in sediment are inherent Ca and Fe sources for biochar modification. In this work, the effect of Ca2+ and Fe2+ released from sediment on biochar for phosphorus adsorption was evaluated.

Saltatory Propagation of Ca2+ Waves by Ca2+ Sparks [PDF]
Punctate releases of Ca2+, called Ca2+ sparks, originate at the regular array of t-tubules in cardiac myocytes and skeletal muscle. During Ca2+ overload sparks serve as sites for the initiation and propagation of Ca2+ waves in myocytes. Computer simulations of spark-mediated waves are performed with model release sites that reproduce the adaptive Ca2 ...

Ontogeny of purinergic receptor-regulated Ca2+ signaling in mouse cortical collecting duct epithelium [PDF]
Changes in ATP-induced increase in {[}Ca2+], during collecting duct ontogeny were studied in primary monolayer cultures of mouse ureteric bud (UB) and cortical collecting duct (CCD) cells by Fura-PE3 fluorescence ratio imaging.

Ca2+ Dependence of the Ca2+-selective TRPV6 Channel [PDF]
Microfluorimetry and patch-clamp experiments were performed on TRPV6-expressing HEK cells to determine whether this Ca(2+)-sensing Ca(2+) channel is constitutively active. Intact cells loaded with fura-2 had an elevated intracellular free Ca(2+) concentration ([Ca(2+)](i)), which decreased to the same level such as in non-transfected cells if external ...

Possible Role of N-Methyl-D-Aspartate Glutamate Receptors in The Induction of Acrosome Reaction in Human Sperm [PDF]
Objective: Acrosome reaction is a receptor and Ca2+-dependent process. N-Methyl-D- aspartate (NMDA) glutamatereceptors are expressed in the human sperm and are involved in the Ca2+ influx.

STIM Is a Ca2+ Sensor Essential for Ca2+-Store-Depletion-Triggered Ca2+ Influx [PDF]
Ca(2+) signaling in nonexcitable cells is typically initiated by receptor-triggered production of inositol-1,4,5-trisphosphate and the release of Ca(2+) from intracellular stores. An elusive signaling process senses the Ca(2+) store depletion and triggers the opening of plasma membrane Ca(2+) channels.

The Electromagnetic potential gradient ,Ca2+ and Starch-Statoliths on the Uneven Growth of Plants
Effect of electromagnetic potential gradients on the uneven growth of shoot apex of Phaseolus vulgaris was investigated. Phaseolus vulgaris plants were fixed to a 3 - D clinostat with microelectrodes which applied an electromagnetic potential gradient (E.
