background: preeclampsia is a disorder of pregnancy without any specific reasons that characterized by high blood pressure and large amounts of protein in the urine. this disorder is caused by multiple factors and finding any factor related to this disorder can help on time prevention of this disease. objective: in this study, serum levels of calcium (ca), magnesium (mg) and zinc (zn) were eval...
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...
background: calcium is the most abundant mineral in the human body. this mineral is provided only by the consumption of foods containing calcium that it is recommended to use at least1300 mg daily for adults. this study is aimed to investigate the nutritional behavior of female high school students about consumption of calcium-rich foods.materials and methodsat a descriptive-analytical study, t...

In order to investigate the interaction effect of salinity and supplementary calcium nitrate on growth, quantitative and qualitative attributes of flowers and mineral composition of Rosa hybrida ‘Ilona’, a factorial experiment was carried out in completely randomized design with three replications. Treatments consisted of four sodium chloride rates (0, 5, 10 and 20 mM sodium chloride) and four ...
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...
Calcium doped nickel ferrite powders have been prepared by sol-gel combustion technique. Metal nitrates, such as calcium nitrate, nickel nitrate and ferric nitrate, were used as the source materials and citric acid and polyvinyl alcohol were used as the burning agent and agglomeration reducing agent, respectively. The average crystallite size of the prepared ferrite was in the order of ~70- 92 ...
