The aim of this study was to investigate the synthesis of calcium aluminate cement with and without phosphate additive by combustion synthesis. After preparing the gel from a solution containing aluminum and calcium nitrates and glycine fuel and ammonium dihydrogen Phosphate, its combustion was performed at 400 ° C. X-ray diffraction pattern and thermal analysis of the combustion sample showed...
Introduction: Preterm delivery is one of the essential midwifery problems, which causes a large proportion of infant mortality even in advanced societies. Despite advances in pregnancy care, the frequency of preterm delivery has not decreased. This study aimed to determine the relationship between serum calcium, phosphorus, and magnesium level with preterm labor in pregnant women. Methods: In ...
Background/Objective: Hyperphosphatemia is the consequence of end stage renal failure. Inadequate control of serum phosphorus results in elevated Ca×P product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification. In this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis patie...
An experiment was carried out on 384 7d old commercial broiler chicks (Lohman) to study the effect of changes in source and level of dietary calcium and limestone particle size on the performance and tibial growth and calcification of broiler chicks. From day 1 to day 7, the chicks were fed with the commercial basal diet. On day 7, the chicks were weighted and randomly assigned to 64 groups, si...

introduction: the aim of this research was to study the effect of a 6-week supplemented diet on increasing bone density by measuring calcium, phosphorus and bone mineral density (bmd) in male rats. materials and methods: in this experimental study, 24 wistar male rats, aged between 15 and 20 days, were selected. the rats were randomly divided into 3 groups: immune system supplement (iss), iss p...
Phosphorus and calcium are essential for bone health. There is a concern that a low calcium/phosphorus intake ratio resulting from low calcium intake coupled with high phosphorus intake may have a negative effect on bone mineral status, especially in Western countries. The objective of this study was to examine cross-sectionally the influence of habitual phosphorus and calcium intake and the ca...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
background: minerals are essential materials in animal reproduction. the determination of these elements is valuable in relation to different conditions in arabian horses. objectives: the purpose of this study was to evaluate the effects of pregnancy on certain macro and micro minerals in arabian horses. methods: blood samples were collected from one hundred apparently healthy mares from differ...
An acidic intravenous source of phosphorus (Addiphos) was compared with dipotassium hydrogen phosphate in 25 preterm infants to study acid-base state. Eight infants were given either Addiphos or dipotassium hydrogen phosphate alternately for 48 hour periods and similar amounts of calcium and phosphorus were delivered. There were no significant differences in calcium and phosphorus intake, calci...
