Polyurethane nanofibers containing calcium chloride (CaCl2) were prepared via an electrospinning technique for the biomedical applications. Polyurethane nanofibers with different concentration of CaCl2 were electrospun, and their bioactivity evaluation was conducted by incubating in biomimetic simulated body fluid (SBF) solution. The morphology, structure and thermal properties of the polyureth...

The objective of this study was to evaluate the storage life and quality of persimmon (Diospyros kaki Thunb.) fruit cv. ‘Karaj’ stored at 0°C for 4 months after postharvest calcium chloride treatment. Fruit weight loss, fruit firmness, total soluble solids, titratable acidity, total phenolic content, soluble tannin content, chilling injury, antioxidant activity, electrolyte leakage, and malondi...

The goal of this study was to determine whether calcium ion, (one of the electrolytes released after plant cell attack), may have a direct e€ect on fungal growth and chemistry of the fungal cell wall. B. cinerea was grown on Richard's solution containing di€erent amounts of CaCl2, and the cell walls were extracted from the mycelium after 7 days of growth. Mineral, neutral and aminosugar, protei...

This study evaluated the influence of the exposure of mineral trioxide aggregate (MTA) - with and without calcium chloride (CaCl2) -to phosphate-buffered saline (PBS) on apical microleakage. Sixty root segments were divided into 4 experimental groups (n=15). Apical cavities were filled with MTA with or without CaCl2, and the root canals dressed with a moistened cotton pellet or PBS: 1) MTA/cott...

Stimulation of beta-adrenergic receptors on LRM55 astroglial cells results in cAMP-dependent release of taurine. We have previously demonstrated that extracellular Ca2+ is not required for either spontaneous or receptor-mediated taurine release (Martin et al., 1988b). In the present series of experiments we investigated the relationship between changes in intracellular free Ca2+ ([Ca2+]i) and t...

The binding of oxygen by the haemocyanin of the gastropod Lymnaea stagnalis was studied by equilibrium and kinetic methods. The studies were performed under conditions in which the haemocyanin molecule was in the native state. Over the pH range 6.8-7.6, in the presence of 10mM-CaCl2 the haemocyanin bound O2 cooperatively. Over this pH range the haemocyanin molecule displayed a normal Bohr effec...

We examined the contribution of the primary hormones of calcium homeostasis to the control of calcium intake in the rat. Male Sprague-Dawley rats with 50 mM CaCl2 solution as their only source of calcium received subcutaneous hormone infusions for 13 days. Parathyroid hormone (PTH; 40, 80, or 160 ng/h) produced sustained dose-related decreases in CaCl2intake. High doses of calcitonin (CT; 32 or...

Natural fluids approximated by the H2O–NaCl–CaCl2 system are common in a wide range of geologic environments, including sedimentary basins associated with hydrocarbon occurrences and MVT deposits, submarine hydrothermal systems, and other metamorphic, magmatic and hydrothermal environments. We present a comprehensive numerical model and Microsoft Excel -based computer program to determine the c...

Fresh-cut fruits are often more perishable and exhibit browning shortly after pulp is cut exposed to natural atmosphere. In this study, fresh-cut peaches were treated with distilled water (control), 20 g L-1 soy protein isolate (SPI), 10 calcium chloride (CaCl2) or + (20 SPI 1.0 CaCl2), respectively, then stored at 0°C assess the protective effects of these treatments on qualities antioxidative...
