Background: Administration of anticoagulant citrate and dextrose (ACD-A) chelates ionized calcium in blood and causes hypocalcemia in plateletpheresis donors. The aim of the study was to observe the effects of oral calcium (Ca) supplementation during plateletpheresis on various parameters related to calcium metabolism.
Materials And Methods: This study was performed between January 2014 and December 2014 on 200 plateletpheresis donors. They were divided into two groups. In group A donors (n=100), no prophylactic oral calcium supplementation was given. In group B (n=100) donors, 2000 mg of calcium was given one hour before the start of the procedure, 500 mg was given at the start of the procedure and 500 mg calcium was given just before the end of procedure. Biochemical parameters like serum total calcium (T Ca), serum total magnesium (T Mg) and ionized calcium level (iCa) were measured before and after the procedure. Relative risk of citrate toxicity was measured between the two groups.
Results: There was a significant fall in total calcium (pre 9.02 mg/dl, post 8.23 mg/dl,), ionized calcium level (pre 1.14 mmol/L, post 0.91 mmol/L) and total magnesium (pre 1.92 mg/dl, post 1.79 mg/dl) amongst the donors who did not receive prophylactic calcium supplementation. Despite calcium intake, in prophylactic calcium intake group, we did observe a significant drop in total magnesium (pre 2.04 mg/dl, post 1.94 mg/dl) and ionized calcium level (pre 1.25 mmol/L, post 1.12 mmol/L, <0.01). We did observe a drop in total calcium level, however, this observation was not statistically significant. The risk (RR=5.44) of citrate toxicity was higher among group A donors.
Conclusion: Prophylactic oral calcium carbonate supplementation would help in to reduce the risk of citrate toxicity. Therefore, we suggest for prophylactic oral administration of 3000 mg elemental calcium carbonate in three divided doses to make PP procedures uneventful.

Calcium supplementation before exercise attenuates the decrease in serum calcium and increase in PTH and bone resorption. This study investigated the effect of calcium supplementation on calcium and bone metabolism during load carriage in women. Forty-eight women completed two load carriage sessions (load carriage 1 n = 48; load carriage 2 n = 40) (12.

Objective: To investigate if changes in body mass index (BMI) result in changes of the mandibular trabecular bone structure.
Materials And Methods: Females (18-35 years at baseline, mean BMI 42,3) were followed from before (n = 117) until two years (n = 66) after obesity treatment (medical or surgical). The mandibular bone trabeculation was classified as sparse, dense, or mixed on intraoral radiographs (Lindh's index).

Chronic cocaine use triggers inflammatory and oxidative processes in the central nervous system, resulting in impaired microglia. Mesenchymal stem cells, known for their immunomodulatory properties, have shown promise in reducing inflammation and enhancing neuronal survival. The study employed the cocaine self-administration model, focusing on ionized calcium-binding adaptor protein 1 (Iba-1) and cell morphology as markers for microglial impairment and PLX-PAD cells as a treatment for attenuating cocaine craving.

Introduction: Neuroinflammation derived from the activation of the microglia is considered a vital pathogenic factor of Alzheimer's Disease (AD). T-006, a tetramethylpyrazine derivative, has been found to alleviate cognitive deficits via inhibiting tau expression and phosphorylation in AD transgenic mouse models. Recently, T-006 has been proven to dramatically decrease the levels of total Amyloid β (Aβ) peptide and Glial Fibrillary Acidic Protein (GFAP) and suppress the expression of ionized calcium binding adaptor molecule-1 (Iba-1) in APP/PS1 mice.

Inducing a transient state of hypocalcemia prepartum mobilizes stored calcium (Ca) before the abrupt demand for Ca at parturition thus more tightly regulating postpartum hypocalcemia. Prepartum transient hypocalcemia can be achieved through intravenous infusions of either the precursor to serotonin, 5-hydroxy-tryptophan (5HTP) or a Ca chelating agent, ethylene-glycol-tetraacetic acid (EGTA). This study aimed to compare the ability of 5HTP and EGTA treatments to prevent postpartum hypocalcemia.
