INTRODUCTION In hypoparathyroidism, calcium supplementation using calcium carbonate is necessary for the hypocalcemia control. The best calcium carbonate intake form is unknown, be it associated with feeding, juice or in fasting. OBJECTIVE The objective was to evaluate the calcium, phosphorus and Calcium×Phosphorus product serum levels of hypoparathyroidism women after total thyroidectomy, fo...

Phosphate-binder therapy for hyperphosphataemia is key to the treatment of patients with chronic kidney disease (CKD)-mineral and bone disorder (MBD). Calcium-free phosphate binders are increasingly favoured since calcium-based agents potentially cause harmful calcium overload and vascular calcification that confound the benefits of reducing serum phosphorus. Several calcium-free phosphate bind...

Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...

Oyster shells have received attention for use as a calcium resource. For this study, calcium phosphate was prepared from phosphoric acid and oyster shells. The influences of the concentration of phosphoric acid and pH in the preparation conditions were studied from the yields of calcium phosphate and unreacted carbonate, and the Ca/P ratios in precipitates. The yield of calcium phosphate and ca...

A mechanism of the transport of nanocrystalline doped calcium carbonatephosphates through the membrane on the model of interaction with phospholipids is considered. Nanocrystalline doped calcium carbonate – phosphates are perspective to transport of the cations in a living cell. Kinetics of the synthesis of nanocrystalline doped calcium carbonatephosphates are non-linear kinetics. Biomaterial b...

Recent dietary life involves frequent opportunities for the ingestion of purified, processed food products and preserved foods, and it has been pointed out that the current dietary mineral intake strongly tends toward nutritional imbalance. The Ryukyu Islands yield coral which contains calcium and magnesium in a content ratio of about 2 to 1, with their approximate contents of 20 and 10%, respe...

We demonstrate a novel approach for synthesizing porosity-controlled calcium carbonate by one-step thermal decomposition of various calcium carboxylate derivatives as well as their mixtures with different molar ratios. By varying the volume content of calcium in the calcium compounds or mixtures, the resulting porous calcium carbonate exhibits distinct porosity and structures that are very prom...

Biomineralization is a known natural phenomenon associated with a wide range of bacterial species. Bacterial-induced calcium carbonate precipitation by marine isolates was investigated in this study. Three genera of ureolytic bacteria, Sporosarcina sp., Bacillus sp. and Brevundimonas sp. were observed to precipitate calcium carbonate minerals. Of these species, Sporosarcina sp. dominated the cu...

abstract the availability of heavy metals in the soil is related to their partitioning between solution and solid phases and expressed by sorption isotherm. twenty surface soil samples (0-30 cm) belonging to five soil subgroups were taken from agricultural regions of western azerbaijan province. the sorption isotherms of pb were determined by equlibrating the soil with solutions containing 0, 1...

background: this study investigated the effects of some important meteorological parameters and filler type compounds on phytotoxicity of captan in peach trees in the north of iran. captan is a phthalimide fungicide which has frequently been used in northern regions of iran to control certain plant diseases. this fungicide has caused intense phytotoxicity in peach trees which was first observed...
