In the field of tissue engineering, electrospinning is a versatile technique that provides nanofibers with structure similar to extracellular matrix owing their flexible functionalization. Considerable developments in have been made produce engineered electrospun for different biomedical applications. Various biopolymers possess good biocompatibility and biodegradability are nontoxic nature. Mo...

The current study was conducted on 10 wells of water located within the city Mosul / left side. quality this evaluated to determine number physical and chemical properties, including acidity, turbidity, total dissolved salts, alkalinity, nitrates, chlorides, phosphates, calcium, magnesium, sulfates. showed that values ​​of solids sulfate rates for well ranged between 155-1150 mg/L, 226-1037mg/L...

Gene transfer methods are promising in the field of gene therapy. Current methods for gene transfer include three major groups: viral, physical and chemical methods. This review mainly summarizes development of several types of chemical methods for gene transfer in vitro and in vivo by means of nano-carriers like; calcium phosphates, lipids, and cationic polymers including chitosan, polyethylen...

The R&D of ceramic biomaterials has extensively progressed in Japan since commercial production of calcium phosphates of hydroxyapatite and β-tricalcium phosphate, A-W glass, chemicalsand SBF (simulated body fluid)-treated metals, and yttria-stabilized zirconia for dental and medical applications. The centers of R&D excellence in Japan consist of universities and national research institutes in...

Autologous bone grafting remains the gold standard for bone grafting in clinical practice. Although it has withstood the test of time, it remains associated with multiple comorbidities. The search for an alternative bone graft substitute harnessing bone's osteoconductive, osteoinductive, and osteogenic properties remains a challenge. This article examines the various bone grafting materials cur...

Receptor-mediated changes in cytoplasmic calcium concentrations occur either through release from intracellular calcium stores or by the opening of channels in the plasma membrane, allowing influx of calcium from the extracellular fluid. Carbachol, a muscarinic receptor agonist, stimulated both calcium influx and inositol 1,4,5-trisphosphate (InsP3)-mediated intracellular calcium release in A9 ...

The blood serum protein and electrolyte levels as well the effects of age, sex time bleeding on these were investigated in a 2x2x2 factorial experiment using twenty four mature guinea fowls(Numedia melagris pallas). results showed fiat proteins major — sodium . (ppm), potassium. (ppm) calcium (mg/100 ml), magkesium ml) phosphates mg/100ml) res­pectively 2.45 ±0.04, 3231 56 ±107.52, 1301. 26 ±33...

The significance of calcium soap formation in the inhibition of calcium absorption has been studied in rats. 47Ca labelled soaps of fatty acids were introduced into the duodenum and the absorption of calcium measured after four hours in a whole body counter. The absorption of calcium was inversely correlated with the chain length of the fatty acid varying from 1% for Ca-stearate to 60% for Ca-h...

The interaction of calcium phosphates with biological molecules under controlled conditions permits the formulation of meaningful conclusions concerning the driving forces. The uptake and release at the material-solution interface is the result of the various interactions between and within the system components which include the solid surface, the adsorbate, the solvent and other solutes prese...
