Both calcium and caffeine induced calcium release from actively loaded heavy sarcoplasmic reticulum vesicles were studied to analyze the dependence of both activities on the composition of the release medium with respect to monovalent anions. Calcium is unable to induce net calcium release while caffeine remains effective as releasing agent when the experimental media contain neither chloride n...

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...

Pollen viability and its germination capability for fruit set in are almond and peach essential. To optimize the pollen culture medium of almond and peach and selection of best medium, the present study was carried out with 48 different culture media containing different compositions including diverse levels of boric acid (0 and 100mg/1), calcium nitrate (0,150and300mg/l،), magnesium sulphate (...

The purpose of this study was to test a gallium nitrate solution, a resorption inhibitor, employed as a root canal dressing in teeth submitted to late replantation. Thirty maxillary right central incisors of rats were avulsed and kept dry for thirty minutes. The teeth were instrumented and the root surfaces were treated with 1% hypochlorite solution followed by application of 2% sodium fluoride...

Calcium (Ca(2+)) serves as a critical messenger in a number of adaptation and developmental processes. In plants, CBL family represents a unique group of calcium sensors that decodes calcium signals. Several CBL members have been functionally characterized in the model plant Arabidopsis thaliana, but the role of CBL7 remains unknown. Here, we report that CBL7 is involved in the regulation of lo...

Abstract: Despite having a number of advantages, reinforced concrete can suffer rebar corrosion in high–chloride media, resulting in failure of reinforced concrete structures. In this research the corrosion inhibition capability of the mixture of calcium and ammonium nitrate of steel rebar corrosion was investigated in the simulated concrete pore solution. Cyclic polarization and Electroche...

AIM To study the effect of gallium nitrate in the treatment of flare hypercalcemia in rats, bearing mammary tumor with bone metastasis. MATERIALS AND METHODS Female Sprague-Dawley albino rats were used in the study. Animals were divided into 5 groups: normal control; hypercalcemic rats bearing DMBA-induced mammary tumors; flare hypercalcemic animals bearing DMBA-induced mammary tumors (hyperc...
