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...

In order to investigate the effect of humic acid (HA) and nano-calcium chelate on the cut flowers of gerbera cv. Dune, an experiment was performed as a completely randomized design with two factors and three replications in hydroponic conditions. The first factor included humic acid at 4 concentrations of 0 (control), 500, 1000, and 2000 mg L-1 as drench and the second factor was ass...

Convincing evidence demonstrates that ionized calcium and not total calcium is the physiologically relevant component of blood calcium. Direct measurement of ionized calcium, however, is limited by difficulties in accurate analysis, lack of standardization, and need for special handling, all resulting in increased cost; therefore, strategies have been developed to estimate ionized calcium from ...

INTRODUCTION Calcium has anti-proliferative and pro-differentiation effects on cells in vitro and can inhibit the development of various cancers. While there is some epidemiologic evidence for an inverse relation between dietary calcium intake and prostate cancer risk, only few have focused on serum calcium levels in this respect. MATERIALS AND METHODS We assayed total serum calcium and ioniz...

Pistachio suffers from some physiological disorders such as fruit abscission, endocarp lesion, blankness, non-split, early-split and deformed nuts. In this experiment, the effects of calcium nitrate (2 gr/lit), calcium chloride (2 gr/lit), boric acid (200 ppm) and their combination treatments were investigated on physiological disorders of ‘Kaleh-Ghoochi’ pistachio. Foliar application was appli...
