The sunlight has an important role in metabolism of calcium ( Ca) and phosphorus ( P). The sunlight has different effects in different places. Therefore  the pattern of metabolic disease depends upon geographical place. In this investigation two groups of workers( one group working in shadow and the other under the sunshine) were chosen as control and experimental groups respectively.these two ...

Phospholipase C (PLC)-mediated hydrolysis of membrane phospholipids results in the production of diacylglycerol, inositol phosphates, and choline metabolites. Inositol triphosphate increases calcium levels, while diacylglycerol activates protein kinase C. The present studies demonstrate that exogenous PLC generates inositol phosphates, releases choline metabolites, and activates protein kinase ...

Abstract Introduction: Achievement of new drugs with minimal side effects is a important goal in the cancer treatment due to irreversible side effects of conventional drugs. Tricalcium phosphates as natural bone components have unique characteristics including excellent biocompatibility, high biosorption and superior bioactivity. This research aimed at investigating the inhibitory effect of tr...

The ability of ionsitol 1,4,5-trisphosphate (IP3) and other inositol phosphates to induce calcium release from canine aortic sarcoplasmic reticulum vesicles was examined. Using the calcium indicator chlorotetracycline or antipyrylazo III, aortic vesicles were shown to accumulate calcium in the presence of ATP, and then release approximately 25% of the intravesicular calcium upon addition of 7 m...

The paper presents directions for a new system technology for municipal wastewater treatment, in order to consider both phosphorus removal and recovery. The system technology is proposed in a way to use as much as possible existing investments for the treatment and focus on modification of the operational mode. The process is based on removal followed by phosphorus recovery as calcium phosphate...

Liposome encapsulation technology has been used to entrap aqueous calcium salts within dipalmitoylphosphatidylcholine lipid vesicles, which were then used to form calcium phosphate minerals. The calcium encapsulation efficiency was found to depend upon a number of factors that included calcium salt concentration, vesicle size, lipid concentration, and method of vesicle preparation. Removal of u...

Hydroxyapatite (HAP) ceramics belongs to a class of calcium phosphate-based biomaterial, which has been widely used as bone substitute for long time. In recent years, synthetic HAP has assumed substantial interest and importance due to its chemical similarity with the natural Ca phosphate mineral present in a biological hard tissue. Considering the wide applications of calcium phosphate compoun...
