In order to improve quantitative and qualitative properties and vase life of rose cv. Dolcvita, an experiment was conducted in a randomized complete blocks design with ten treatments and three replications in a hydroponic greenhouse adjacent to Yasouj city, Iran. Treatments included control, spermidine (0.5, 1 and 1.5 mM), calcium sulfate (2.5 and 5 mM), spermidine 0.5 mM+ calcium sulfate 2.5 m...
This article addresses the interplay between heat of hydration and physico-mechanical properties of calcium sulfate hemi-hydrate in the presence of retarding additives such as citric and malic acids and sodium citrate. The heat of hydration was measured using a semi-isothermal calorimeter. Results proved that citric and malic acids had superior impact on hydration and mechanical properties. Whi...
Differential heating curves were used to study the behavior of calcium sulfate at high temperatures. After cooling, the material was examined by means of the petrographic microscope and by study of its X-ray pattern. It was found that the beta-to-alpha transition of calcium sulfate occurs at approximately 1,214° C, and the conclusion of i ts discoverer that the high temperature form is unstable...
Background and Aim: Medical grade calcium sulfate hemihydrate (MGCSH) is used as a bone graft material for socket preservation. This study aimed to evaluate the changes in bone width and height after tooth extraction and socket preservation with MGCSH using cone-beam computed tomography (CBCT). Materials and Methods: This study evaluated 17 systemically healthy patients over a 1-year period. Th...
RATIONALE Transient receptor potential melastatin (TRPM)3 is a calcium-permeable ion channel activated by the neurosteroid pregnenolone sulfate and positively coupled to insulin secretion in beta cells. Although vascular TRPM3 mRNA has been reported, there is no knowledge of TRPM3 protein or its regulation and function in the cardiovascular system. OBJECTIVE To determine the relevance and reg...
