BACKGROUND Calcium (Ca)- magnesium (Mg) imbalance is implicated in prostate cancer. Ca/Mg ratio increases or decreases with proliferation or apoptosis, respectively. The study examined whether this Ca/Mg imbalance exists in BPH patients and the effect of a phytotherapeutic drug on the Ca/Mg ratio. METHODS Thirty (30) BPH patients who used the ethanolic root extract of Croton membranaceus (60 ...

In cardiac muscle, intracellular Ca(2+) and Mg(2+) are potent regulators of calcium release from the sarcoplasmic reticulum (SR). It is well known that the free [Ca(2+)] in the SR ([Ca(2+)](L)) stimulates the Ca(2+) release channels (ryanodine receptor [RYR]2). However, little is known about the action of luminal Mg(2+), which has not been regarded as an important regulator of Ca(2+) release. T...

To investigate uterine fluid and serum calcium (Ca) and Magnesium (Mg) variations during the estrus cycle in water buffaloes, 71 genital tracts and blood samples were collected from the abattoir in Urmia. The phase of the estrous cycle was determined by examining ovarian structures. 18 animals were pro-estrous, 15 estrous, 16 met-estrous and 22 diestrous. The uterine fluid was collected by gent...

in a greenhouse experiment, the effects of waterlogging, sewage sludge and manure on the uptake and concentrations of p, k, ca, mg and na in root and shoot of sunflower (helianthus annuus l.) were investigated. a factorial experiment based on completely randomized design with three replications including duration of waterlogging at five levels (0, 2, 4, 8, 22 days), source of organic fertilizer...

an experiment was conducted to investigate the effects of fruit hydroalcoholic extract of withania coagulans (wc) and 1, 25-dihydroxycholecalciferol on bone mechanical and histological properties of male chickens. diets were arranged factorially (2×3×2) consisted of a positive control with adequate ca (10.4 g/kg diet) and nonphytate p (npp; 5 g/kg diet) exceed the requirements suggested in the ...

In cardiac muscle, Ca(2+)-induced Ca(2+) release (CICR) from the sarcoplasmic reticulum (SR) defines the amplitude and time course of the Ca(2+) transient. The global elevation of the intracellular Ca(2+) concentration arises from the spatial and temporal summation of elementary Ca(2+) release events, Ca(2+) sparks. Ca(2+) sparks represent the concerted opening of a group of ryanodine receptors...

Many patients with thyrotoxicosis develop hypercalciuria and nypercalcemia. Urine calcium excretion depends on diet, latitude and sunshine exposure. With regard to variation of these indices in different geographical regions, we conducted a one-year study on 202 patients, 65 males and 137 females, with thyrotoxicosis of varying severity. The mean age of patients was 35.24±11.95 and 35.87±1...
