prevention and treatment of the rickets of prematurity is an important aspect of the care of preterm infants. the purpose of this study was to compare the prophylactic effects of different doses of vitamin d on the clinical, biochemical and radiological indices of the rickets of prematurity. in a randomized clinical trial, 68 premature infants (<38 weeks) with birth weight under 2000 g, randoml...

Alkaline phosphatase activity and calbindin-D9K immunoreactivity are decreased in the intestines of spontaneously hypertensive rats (SHRs). To investigate the potential role of altered gene expression in these decreases, we measured, by Northern blot analyses, the abundances of alkaline phosphatase and calbindin-D9K mRNAs in the proximal regions of the small intestines of 14-week-old SHR and co...

Alkaline phosphatase serves both as a model enzyme for studies on the mechanism and kinetics of phosphomonoesterases and as a reporter in enzyme-linked immunosorbent assays (ELISAs) and other biochemical methods. The tight binding of the enzyme to its inorganic phosphate product leads to strong inhibition of catalysis and confounds measurements of alkaline phosphatase activity. We have develope...

The kinetics of hydrogen evolution reaction (HER) was studied in 1M NaOH at various temperatures (298 to 358 K) on Ni-P-C (composite electrodes. The electrochemical efficiency of the electrodes has been evaluated on the basis of electrochemical data obtained from the steady-state polarization Tafel curves, electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) in 1M NaOH solut...

Background: Due to different such as some sexrelated illnesses, spouses have been encourage to designate special treatments for assessing sexuality. Moreover, Utilizing from identifying sexulityb has been an important aim in industry in order to product humans needs and develop cattle. In this research, the effect of alkaline environments were examined migration spermatozoa for sex selection. M...

Background: There are different factors Tahat effect in sex selection such as the best medium treatment.These techniques can be used in live stock industry for product in ordre to humans need. Materials and Methods: Forty mice (NMRI) were divided in to a control group and three experimental group. Ovulation of mice was stimulated by using PMSG and HCG hormones. Female mice were killed by cervic...

The aim of this study was to Investigate the toxic effects of chromium and cadmium on the activity of two isoenzymes of alkaline phosphatase in vitro and in vivo experiments. Oral administration and peritoneal injection of  CdCl2 or CrCl3 in rats reduced serum alkaline phosphatase by 21.5℅ and 25.5℅ respectively. At the same time high molecular weight alkaline phosphatase was elevated by 138℅ a...

Osteocalcin or bone gamma-carboxyglutamic acid (gla) protein and Bone-specific alkaline phosphatase (b-AP) total protein levels were evaluated as indicators of bone turnover in twenty patients with sickle cell haemoglobinopathies and in twenty normal healthy individuals. The serum bone-specific alkaline phosphatase total protein level was measured by immunoradiometric (IRMA) method. The concent...

STATEMENT OF THE PROBLEM Alkaline pH can affect the physical and chemical properties and sealing ability of apical plug material. Calcium hydroxide is used as an intracanal medication to complete disinfection of root canals. It raises the pH of environment to alkaline value. PURPOSE The aim of this in vitro study was to evaluate and compare the effect of alkaline pH on the sealing ability of ...
