The purpose of this study is to gain a better understanding of calcium absorption and metabolism in patients with Chronic Kidney Disease (CKD) using calcium balance and kinetic methods.
Hypoparathyroidism is an endocrinopathy characterized by a deficient secretion or action of PTH associated with low calcium level. According to the European guideline (2015), standard trea...
This study will evaluate the effectiveness of taking supplemental calcium while pregnant in reducing the risk of postpartum depression.
Patients diagnosed with, or in risk of osteoporosis regularly take calcium dietary supplements, although their contribution to BMD maintenance, prevention of bone loss or reduction of the ...
Interventional Clinical trial with food supplement, randomized, double-blind, comparative between microencapsulated calcium, calcium carbonate salts standardized and calcium citrate, in a ...
Following Roux-en-Y gastric bypass (RYGB), elevated parathyroid hormone (PTH) levels potentially harmful to bone health are commonly observed. Owing to assumed superior absorption, calcium citrate is ...
Calcium carbonate was previously shown to interfere with L-thyroxine absorption. To estimate the magnitude of tablet L-thyroxine malabsorption caused by calcium carbonate, with resulting increase in s...
Calcium gradient, the difference between serum calcium and dialysate calcium d[Ca], is the main contributor factor influencing calcium transfer during hemodialysis. The impact, however, of bone turnov...
Sex-specific effects of pregnancy calcium carbonate supplementation have been reported in 8-12 year old Gambian children, indicating faster growth in boys but slower growth in girls born to calcium-...
Evidence shows that adequate calcium intake during pregnancy reduces the risk of hypertensive disorders of pregnancy. In most low-and-middle-income countries (LMICs) daily calcium intake is well below...
Carbonic acid calcium salt (CaCO3). An odorless, tasteless powder or crystal that occurs in nature. It is used therapeutically as a phosphate buffer in hemodialysis patients and as a calcium supplement.
Signal transduction mechanisms whereby calcium mobilization (from outside the cell or from intracellular storage pools) to the cytoplasm is triggered by external stimuli. Calcium signals are often seen to propagate as waves, oscillations, spikes, sparks, or puffs. The calcium acts as an intracellular messenger by activating calcium-responsive proteins.
Intracellular signaling peptides and proteins that bind to CALCIUM. They undergo allosteric changes when bound to CALCIUM that affects their interaction with other signal-transducing molecules. They differ from CALCIUM-SENSING RECEPTORS which sense extracellular calcium levels.
A class of G-protein-coupled receptors that react to varying extracellular CALCIUM levels. Calcium-sensing receptors in the PARATHYROID GLANDS play an important role in the maintenance of calcium HOMEOSTASIS by regulating the release of PARATHYROID HORMONE. They differ from INTRACELLULAR CALCIUM-SENSING PROTEINS which sense intracellular calcium levels.
A stromal interaction molecule that functions in the regulation of calcium influx following depletion of intracellular calcium in the ENDOPLASMIC RETICULUM. It translocates to the plasma membrane upon calcium depletion where it activates the CALCIUM RELEASE ACTIVATED CALCIUM CHANNEL ORAI1.
