Blossom-end rot (BER) is one of the physiological disorders related to calcium (Ca) deficiency in the fruit which reduces yield and fruit quality of bell pepper (Capsicum annuum L.). Every year, occurrence of BER in bell pepper of Shahreza greenhouses causes a loss to farmers of this vegetable. This experiment was conducted to elucidate the effects of foliar application of calcium sources and r...
Introduction: Menopause is the natural termination of menstruation, which affects the quality, and important aspects of women life. The aim of this study was to investigate regular resistance training along with vitamins D and calcium intake in the pre-menopausal period on bone mineral density (BMD) in rats. Methods: In this experimental study, the rats were randomly divided into control grou...
a systematic review on the effects of maternal calcium supplementation on offspring’s blood pressure
background: evidence proposes that maternal calcium (ca) supplement during pregnancy may be inversely associated with the off spring’s blood pressure (bp) level. it is suggested that increased maternal ca intake during pregnancy may result in lower bp in the off spring. the reduction in the incidence of hypertension in mothers is documented but the effects on the off spring are uncertain.mater...
The objective of the present study was to investigate the effect of calcium supplementation on prevention of pregnancy induced hypertension. A randomized clinical trial of calcium supplementation in pregnancy versus no Ca supplementation was performed on 400 primigravida with 20 completed weeks of pregnancy. 200 patients(Ca supplementation) and 200 patients(without Ca supplementatio...
summer pruning and calcium spray could improve kiwifruits quality. in this study, effect of summer pruning in two times, 2 and 15 days after petal fall alone or in combination with %1 calcium chloride spray on fruit quality and mineral elements contents of ‘hayward’ kiwifruit was investigated. calcium sprayed four times 90 days after petal fall with 15 days intervals. the results showed that su...
Nanocrystalline hydroxyapatite was precipitated from calcium hydroxide and phosphoric acid. Effects of precipitation temperature and different calcium to phosphate ratios (Ca/P) on the obtained powders were investigated. Characteriza-tion of the powders was performed using XRD and FTIR spectra, scanning electron microscopy, and transmission electron microscopy. Increase in precipitation t...
nanocrystalline hydroxyapatite was precipitated from calcium hydroxide and phosphoric acid. effects of precipitation temperature and different calcium to phosphate ratios (ca/p) on the obtained powders were investigated. characteriza-tion of the powders was performed using xrd and ftir spectra, scanning electron microscopy, and transmission electron microscopy. increase in precipitation tempera...
the interaction between sodium and calcium, magnesium and calcium and the combined effect of sodium, magnesium and calcium was observed on the growth and ion uptake of hippophae rhamnoides l. the results demonstrated that an addition of sodium with calcium, (set a, na 2.5 + ca 5 mm) showed prominent increase in fresh weight of roots and shoots. the dry weight (average) of roots decreased and th...
The primary aim of this study was to assay the influence of dietary Ca sources and levels on performance, egg quality indices, and selected blood variables of laying hens. A total of 192 Bovanz commercial layers were distributed to 6 dietary treatment groups with 4 replicates and 8 birds in each replicate. The experimental diets were iso-caloric and iso-nitrogenous, but they were different in t...
