The Effect of Dietary Fats Containing Trans-Octadecenoates on Calcium Transport and Membrane Properties of The Rat Erythrocyte
The response of rat erythrocyte membrane fatty acids to dietary fat of widely differing fatty acid composition was investigated. The red cell fatty acids were susceptible to dietary influence in a very specific manner. An increase of linoleic acid in the diet resulted in higher levels of 9,12-c,c, …

Informing Therapeutic Approaches For Infectious Disease And Heart Disease, Focusing On Cell-Free Synthesis Of Bacteriophages And Calcium Transport By Serca
… SERCA, PLB, and DWORF regulate intracellular calcium transport in cardiac muscle. I detail the methodology behind purifying and co-reconstituting these membrane proteins in vesicles, and I present the dynamical information of these proteins obtained by EPR spectroscopy. My experimental …

Effects of dietary calcium, phytoestrogen rich diets and estrogen on intestinal calcium transport proteins, egg and eggshell quality in maturing layer hens / Ali Asghar Saki.
… estrogen modulates the proteins associated with calcium transport (eg calcium binding protein, calbindin D28k) in the intestinal tissue during sexual maturation of laying hens. Studies the temporal and spatial expression of estrogen receptors (ER) and calcium binding protein in jejunal tissue. …

Pattern and Mechanism of Calcium Mobilization During Embryonic Development in a Viviparous Snake, <em>Virginia striatula</em>.
<p>Yolk supplies the majority of embryonic calcium in snakes. Oviparous and viviparous snakes also receive calcium late in development from the eggshell and placenta, respectively. The pattern and mechanism of calcium transport are partly understood for oviparous snakes. I studied a viviparous …

Calcium homeostasis in Escherichia coli
<p>While the role of calcium ions as secondary chemical messengers has been well described in eukaryotic cells, little is known about calcium homeostasis in bacteria at the physiological and molecular level. No calcium influx gene has been identified so far. This dissertation focuses on calcium …

Binding and transport of calcium by synthetic analogues of ionomycin
… oxidation of theP-diketo tau-alcohols. The transport of calcium across an organic barrier by these synthetic analogues of ionomycin was determined in a cylindrical glass cell using chloroform as the artificial membrane. The presence of the P-diketone and carboxyl groups within the same …

Membrane reconstitution studies on the irreversibility of inactivation of sarcoplasmic reticulum of rabbit skeletal muscle
… ether) - N,N' - tetraacetic acid inactivates calcium transport by sarcoplasmic reticulum membranes but does not inhibit calcium stimulated ATPase activity. This inactivation is apparently irreversible. The purpose of the present study was to determine whether lipid-protein interactions, …

Conformational changes in the (Ca²⁺, Mg²⁺)-ATPase of sarcoplasmic reticulum during energy transduction
… in a progressive irreversible inhibition of calcium transport while (Ca²⁺, Mg²⁺)-ATPase activity is unimpaired. Possible conformational changes associated with this uncoupling were monitored by following alterations in kinetic mobility of sulphydryl (-SH) groups either by using 5, …

Spatio-Temporal Calcium Dynamics of the Interstitial Cells of Cajal
… which are in turn linked to the integrated transport of calcium between the endoplasmic reticulum (ER), through inositol-trisphosphate receptor (IP3R) release, and mitochondria, through the uniporter. In the intestinal regions, a non-specific cation channel (NSCC) is associated with the …

Structure and function of sarcoplasmic reticulum isolated from slowly and from rapidly-glycolysing skeletal muscle
… a rapid post-mortem decline in pH has impaired calcium-accumulating ability when compared with that from normal muscle which has a slow rate of pH decline (Greaseret al., 1969a). The enzyme responsible for translocating the cations, namely the ATPase protein, was less affected. The implication …

Role of transient receptor potential channels in mammalian oviduct and uterine epithelia
Calcium is an important secondary messenger and plays a major role in cell function, including proliferation, cell growth, secretion and death .It also plays a critical role in uterine smooth muscle contraction and embryo implantation. This thesis is concerned with calcium homeostasis in epithelial …

Towards the development of calcium ion batteries
A novel system for the study of calcium-ion electroactive materials has been developed, characterized, and utilized to screen a number of candidate calcium intercalation compounds. The system is comprised of a dried, pre-electrolyzed calcium perchlorate salt in acetonitrile solvent electrolyte …

The calcinogenic principles of Trisetum flavescens
… and shown to promote intestinal phosphate transport and increase plasma phosphate levels. This factor was shown to influence the movement of phosphate from the serosa to the bloodstream but not direct uptake from the intestinal lumen. This substance was found to be unlike vitamin D3 or its …

Low Bone Mineral Density is not related with High Coronary Artery Calcium Score but with High Hair Calcium: The Relationship among different Calcium Pools in Body
BACKGROUND: With aging, calcium efflux from bone increased as age-related bone loss reduces bone mineral density and age-related calcium adoption in arterial wall progressively stiffens blood vessels, insinuating calcium exchange among different calcium pools in body however these relationships …

Effects of copper on calcium metabolism and detoxification mechanisms in freshwater bivalve species of Anodonta
… Cu2+ effects on cellular plasma membrane calcium transport were studied first. In the second step, the investigations focused on Cu2+ detoxification mechanism involving cysteine (Cys) rich compounds known to play a major role in homeostasis of essential trace metals and in cellular metal …

Structural studies on the plant plasma membrane calcium-ATPase
… membrane protein that mediates the active transport of calcium out of the cytoplasm into the cell exterior. In plant cells it is believed to play a major regulatory role in signal transduction by helping to maintain a large gradient of calcium across the plasma membrane, thereby keeping the …
