background: association between the vitamin d deficiency and metabolic syndrome (mets) has previously been noted and reported to be controversial. the aim of this study was to determine the association of serum 25 (oh) d level and vitamin d dietary intake with mets among iranian population . methods: this analytical study was conducted on 122 patients with mets based on the atpiii criteria and ...

BACKGROUND Mineral disorders are associated with adverse renal outcomes in chronic kidney disease (CKD) patients. Previous studies have associated hypercalcemia and hypocalcemia with mortality; however, the association between serum calcium and renal outcome is not well-described. Whether adding calcium besides phosphorus or in the form of calcium-phosphorus (Ca×P) product into the model of sur...

background: osteopenia is common problem in premature infants. low-birth weight babies do not receive adequate amounts of calcium and phosphorus through breast feeding. this study examines the effect of calcium and phosphorus supplements on osteopenia in premature infants. methods: this clinical trial included 42 premature infants hospitalized at razi hspital in kermanshah. all the babies had a...

Musilova A., Lichovnikova M., Kupcikova L., Anderle V. (2017): Effect of suboptimal levels of non-phytate phosphorus and exogenous phytase on precaecal digestibility of phosphorus and calcium in laying hens. Czech J. Anim. Sci., 62, 473–481. The precaecal digestibility of phosphorus and calcium in laying hens was evaluated at two dietary levels of non-phytate phosphorus (NPP; 1.58 and 2.03 g/kg...

abstract background: to determine daily calcium, vitamin d intake and serum biochemical findings of rickets in adolescent girls. methods: a total of 414 healthy adolescent student girls aged 11-15 years were evaluated from various areas of tehran, iran with different socioeconomic status. a randomized, cross-sectional, prospective and descriptive study was undertaken for calculation of daily ca...

In a series of investigations on the relation of the thyroid to calcium and phosphorus metabolism Aub and his coworkers (1) have demonstrated that increased thyroid activity is associated with an increased excretion of calcium and phosphorus. In exophthalmic goiter there is an increased output of calcium not only in the urine but in the feces. In normal individuals who are fed thyroid there is ...

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...

Minerals play an essential role in the normal vital process.Calcium, phosphorus and magnesium are the most abundant minerals. Vitamin D and parathyroid hormone play a key role in regulation of their homeostasis as well. The aim of this study was to evaluate calcium, phosphorus, magnesium, vitamin D and parathyroid hormone on 30 Caspian horses of Guilan Province (south of the Caspian Sea) in two...

In addition to their role in the development and maintenance of the skeleton in pigs, calcium and phosphorus are involved in many other physiological processes. In practical swine diets, calcium can be considered an inexpensive nutrient. Phosphorus, on the other hand, is the third most expensive nutrient after energy and protein (amino acids). As the utilization of phosphorus in swine diets is ...
