Perfusion of the isolated rat heart with Ca2+ concentrations exceeding 3 mM activated phosphofructokinase and phosphorylase, and decreased the concentration of cyclic AMP. Half-maximal activation of phosphofructokinase occurred at 5 mM-CaCl2; significant activation of phosphorylase did not occur until the concentration of CaCl2 exceeded 12 mM. The time course for the activation of phosphofructo...

The objective of this study was to evaluate the sealing ability and antibacterial activity of Ca3SiO5/CaCl2 composite cement. Fifty maxillary anterior teeth were instrumented according to step-back technique and filled with experimental and control materials. To evaluate the sealing ability, a fluid transport model using glucose was employed for quantitative analysis of endodontic microleakage....

Background/Aim: This in-vitro study evaluated the apical-sealing ability of MTA, MTA+10% CaCl2, Biodentine™ and RMGIC when used as retrograde material. Material Methods: A total 80 single-rooted bovine incisors were decoronated, instrumented, divided into 4 groups according to material, follows: Group 1: MTA (ProRoot Dentsply); 2: Dentsply) + 10% CaCl2; 3: Biodentine (Biodentine®, Septodont); 4...

Phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (P) forms to soluble and bioavailable P. The aim of the present study was to isolate P solubilizing bacteria from forest soils around the rock phosphate (RP) mine of Koh-e-SepidLar in Kohgiluyeh and Boyer Ahmad province and evaluate their ability in Sperber culture medium and wheat straw medium in the presen...

The objective of this study was to evaluate the effect of the concentration of calcium chloride (CaCl2) solution on the surface hardness of restorative glass ionomer cements (GICs). Two high-viscosity GICs, Fuji IX GP and GlasIonomer FX-II, were immersed in several concentrations of CaCl2 solution for 1 day and 1 week. The immersed specimen surfaces were evaluated using microhardness testing, g...

Rosa hybrida L. is an important commercial cut flower. Salicylic acid (SA) and calcium chloride (CaCl2) act as endogenous signal molecules responsible for growth parameters in plants. The aim of this study was to evaluate the effects of preharvest SA and CaCl2 treatments in extending the vase life of cut rose flowers. Therefore, a factorial experiment based on completely randomized design with ...

Chloride molten salts have become a potential heat storage material for the design of new generation concentrating solar power (CSP) (>700 °C) due to its abundant reserves and low cost. The difficulty measuring high-temperature thermal properties chlorides can be effectively solved by using molecular dynamics simulation. However, it is challenging get thermophysical multi-component containin...

We examined the effectiveness of intermittent warming (IW), hot water (HW), salicylic acid (SA), and calcium chloride (CaCl2) on the postharvest life of pomegranate fruit cv. ‘Shishe-Kab’ and extending fruit shelf life during cold storage (3°C). Fruit were subjected to cycles of 1 d at 17 ± 1°C every 6 d of storage at 3°C under IW conditions. Pre-storage treatments were HW (50°C) for 3 min, SA ...
