Aim: The role of vitamin D has been studied in growth and reproduction, carcinomas, psoriasis etc. Even in preeclampsia aberration in calcium homeostasis was found to be associated with decreased calcitriol levels. In present study, we investigated the role of vitamin D supplementation in regulation of calcium homeostasis and prevention of preeclampsia. Methods: The study comprised of 200 primi...

Vitamin D supplementation effects with or without calcium in pregnancy for reducing risk of preeclampsia and gestational or pregnancy induced hypertension are controversial. Literature was systematically searched in Medline, Scopus and Cochrane databases from inception to July 2017. Only randomized controlled trials (RCTs) in English were selected if they had any pair of interventions (calcium,...

BACKGROUND Chronic renal failure has been referred to as a state of cellular calcium toxicity. The aim of this study was to investigate the status of free cytosolic calcium ([Ca(2+)](i)), intracellular calcium reserves and the capacitative calcium entry in peripheral blood mononuclear cells (PBMCs) of early-stage chronic kidney disease (CKD) patients, and to determine the effect of vitamin D(3)...

To determine whether dietary calcium supplementation affects esophageal precancerous lesions, 200 subjects with esophageal lesions in a high-risk area for esophageal cancer in China (Huixian, Henan) were randomly divided into 2 groups (100 subjects/group). Subjects in one group received an oral supplementation of calcium carbonate tablets (1200 mg of calcium daily), and subjects in the other gr...

AIMS In breast cancer survivors, we aimed to describe the frequency of hot flashes and night sweats, frequency and type of treatment, and the association of hot flashes and use of calcium supplements. METHODS Charts of breast cancer survivors were reviewed for information about hot flashes, treatment for hot flashes, and calcium supplementation. Associations between variables were explored us...

BACKGROUND Prenatal lead exposure is associated with deficits in fetal growth and neurodevelopment. Calcium supplementation may attenuate fetal exposure by inhibiting mobilization of maternal bone lead and/or intestinal absorption of ingested lead. OBJECTIVE Our goal was to evaluate the effect of 1,200 mg dietary calcium supplementation on maternal blood lead levels during pregnancy. METHOD...

Abstract Trichoderma reesei RUT-C30 is a well-known high-yielding cellulase-producing fungal strain that converts lignocellulose into cellulosic sugar for resource regeneration. Calcium ubiquitous secondary messenger regulates growth and cellulase production in T. . We serendipitously found adding Sr 2+ to the medium significantly increased activity upregulated expression of cellulase-related g...

BACKGROUND Regional citrate anticoagulation is a very effective anticoagulation method for haemodialysis. However, it is not widely used, primarily due to the risk of hypocalcaemia. We studied citrate and calcium kinetics to better understand safety aspects of this anticoagulation method. METHODS During 15 haemodialysis treatments with a calcium-free dialysis solution, citrate was infused pre...

BACKGROUND Bariatric surgery, especially Roux-en-Y gastric bypass, can cause serious nutritional complications arising from poor absorption of essential nutrients. Secondary hyperparathyroidism is one such complications that leads to increased parathyroid hormone levels due to a decrease in calcium and vitamin D, which may compromise bone health. AIM To compare calcium carbonate and calcium c...

OBJECTIVE to study the effects of different doses of calcium intake on bone health and body composition in Chinese adolescents. METHODS a double-blind randomized controlled trial of calcium carbonate supplementation in 257 healthy adolescents aged 12-15 years old for 24 months. Subjects were randomly assigned to four groups receiving chewable calcium carbonate tablets providing elemental calc...
