Rapid kinetic studies of SH oxidation-induced calcium release from sarcoplasmic reticulum vesicles
(Academic Press Inc., 1997)
We studied the kinetics of calcium release induced by SH oxidation in triads isolated from frog and rabbit skeletal muscle by measuring calcium fluxes by a fast filtration method. In both species SH oxidation induced release ...
Regulation of intestinal calcium absorption by luminal calcium content. Role of intestinal alkaline phosphatase
(Wiley VCH Verlag, 2014-03)
Scope: Intestinal alkaline phosphatase is a brush border enzyme that is stimulated by calcium. Inhibition of intestinal alkaline phosphatase increases intestinal calcium absorption. We hypothesized that intestinal alkaline ...
Signal transduction and gene expression regulated by calcium release from internal stores in excitable cells
(SOCIEDAD BIOLOGIA CHILE, 2004)
Calcium regulation of several transcription factors involves different calcium-dependent signaling cascades and engages cytoplasmic as well as nuclear calcium signals. The study of the specific sources of calcium signals ...
Regulation of Intercellular Calcium Signaling Through Calcium Interactions with Connexin-Based Channels
(2012)
The synchronization of numerous cellular events requires complex electric and metabolic cell-cell interactions. Connexins are a family of membrane proteins that constitute the molecular basis of two kinds of channels: gap ...

Sodium-calcium exchange in transverse tubules isolated from frog skeletal muscle
(1989)
Transverse tubule vesicles isolated from frog skeletal muscle display sodium-calcium exchange activity, which was characterized measuring 45Ca influx in vesicles incubated with sodium. The initial rates of exchange varied ...
Osteogenesis-inducing calcium phosphate nanoparticle precursors applied to titanium surfaces
(2013-05-20)
This study investigated the effects of the morphology and physicochemical properties of calcium phosphate (CaP) nanoparticles on osteogenesis. Two types of CaP nanoparticles were compared, namely amorphous calcium phosphate ...
