Hydroxyapatite (HA) is one of the most important calcium phosphate minerals due to its application in orthopaedics and dentistry. The applications of the synthesized HA powder depend upon the morphology of the HA. In this research, hydroxyapatite crystal nanowires are synthesized by simple hydrothermal method from clamshells.

=Stimulated by the depletion of phosphate resources and the need to avoid eutrophication, phosphate removal/ recovery has been studied in recent years. The aim of this study is to investigate the feasibility of phosphate recovery from wastewater by the hybrid system consisting of pellet reactor and selectrodialysis. The phosphates will be pre-concentrated in the selectrodialysis and then be recovered by a crystallization process where it will precipitate on to sand grains as calcium phosphate in a pellet reactor

Cartilage calcification (CC) is associated with osteoarthritis (OA) in weight-bearing joints, such as the hip and the knee. However, little is known about the impact of CC and degeneration on other weight-bearing joints, especially as it relates to the occurrence of OA in the ankles.

The inhibitory effect of Bluméa balsamifera extract on the nucleation, growth, and aggregation phases of calcium oxalate formation has been studied. Plant samples were extracted by the maceration method with 80.00% ethanol. The results showed that the moisture content of Bluméa balsamifera extract was 82.83% and the yield was 5.79%. Bluméa balsamifera extract contains bioactive compounds including alkaloids, flavonoids, saponins, terpenoids, tannins, and phenol.

Calcium sulfate beads (CSBs) are biocompatible hydrophilic crystals that are used to deliver local antibiotics in periprosthetic joint infections. Hypercalcemia after placement of CSBs is uncommon and poorly understood.

Results from light, scanning, and transmission electron microscopic examination of CaOx crystal formation in 2 plant species, namely Corchorus olitorius L. and Malva parviflora L., revealed the presence of crystalline deposits. These deposits were of prismatic type in the case of C. olitorius and of druse type in the case of M. parviflora.

In the samples, various epidermal features were identified in the spur that developmentally are invaginations of the labellum and the adaxial surface of the labellum. Typical secretory cells and inclusions such as starch or calcium oxalate crystals of different sizes and shapes were found within the structure of individuals.

Crystal types from 3 oak species representing 3 different sections of the genus Quercus were identified. Crystals were studied with scanning electron microscopy after localisation by light microscopy. The crystals were composed of calcium oxalate silicates as whewellite (calcium oxalate monohydrate) composites.

In this study, we isolated a 25-kDa novel snake venom protein, designated ablomin, from the venom of the Japanese Mamushi snake (Agkistrodon blomhoffi). The amino-acid sequence of this protein was determined by peptide sequencing and cDNA cloning. The deduced sequence showed high similarity to helothermine from the Mexican beaded lizard (Heloderma horridum horridum), which blocks voltage-gated calcium and potassium channels, and ryanodine receptors. Ablomin blocked contraction of rat tail arterial smooth muscle elicited by high K+-induced depolarization in the 0.

In seminiferous tubules, Sertoli cells provide structural and nutritional support for the developing germinal cells. Cellto-cell signaling and cell adhesion require proteoglycans expressed at the cell membrane. A preliminary biochemical and structural approach indicated that cell surface proteoglycans are mostly heparan sulfate proteoglycans (HSPG). Glypican-1, syndecans-1 and -4 were identified using a molecular approach.

In late larvae of the blowfly, Calliphora vicina, arylphorin and LSP-2 proteins, which belong to the class of hexamerins, are selectively taken up by the fat body from the haemolymph. Hexamerin endocytosis is mediated by a specific membranebound receptor, the arylphorin-binding protein (ABP). Using the two-hybrid technique, we found that the anterior fat body protein (AFP) interacts with the hexamerin receptor.

Chimeric calcium/calmodulin dependent protein kinase (CCaMK) is characterized by the presence of a visinin-like Ca 2+ -binding domain unlike other known calmodulin-dependent kinases. Ca 2+ -Binding to the visinin-like domain leads to autophosphorylation and changes in the affinity for calmodulin [Sathyanarayanan P.V., Cremo C.R. & Poovaiah B.W. (2000)J. Biol. Chem. 275, 30417–30422]. Here, we report that the Ca 2+ -stimulated autophosphory-lation of CCaMK results in time-dependent loss of enzyme activity. ...

The present study was conducted on human Jurkat T-cell lines in order to elucidate the role of phospholipase A2in capacitative calcium entry. We have employed thapsigar-gin (TG)that induces increases in [Ca 2+ ] i by emptying the calcium pool of endoplasmic reticulum, followed by capacitative calcium entry. We designed a Ca 2+ free/Ca 2+ reintroduction (CFCR)protocol for the experiments, conducted in Ca 2+ -free medium.

Gelsolin is a multidomain and multifunction protein that nucleates the assembly of filaments and severs them. The activation of gelsolin by calcium is a multistep process involving many calcium binding sites that act to unfold the molecule from a tight structure to a more loose form in which three actin-binding sites become exposed. Low pHis alsoknowntoactivategelsolin, in theabsenceof calciumand this too results in an unfolding of the molecule.

In the leukemic macrophage cell-line THP-1, a fraction of the secreted matrix metalloproteinase 9 (MMP-9) is linked to the core protein of chondroitin sulfate proteoglycans (CSPG). Unlike the monomeric and homodimeric forms of MMP-9, the addition of exogenous CaCl2 to the proMMP-9/CSPG complex resulted in an active gelatinase due to the induction of an autocatalytic removal of the N-terminal prodomain.
