‘Golden Delicious’ apples (Malus /domestica Borkh.) were either untreated or pressure-infiltrated after harvest with 0, 1, 2, 3 or 4% CaCl2 solutions (w/v) and stored at 0 8C for up to 6 months. The chemical composition of the fruit cortical tissue and cell walls of the 2 /4 mm layer under the epidermis was studied. Storage of untreated fruit resulted in a decrease in K, P, Mg, S and Suc conten...

INTRODUCTION This in vitro study investigated the effect of adding 10% calcium chloride (CaCl2) on push out bond strength of calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA) to root canal dentin. METHODS AND MATERIALS A total of 120 root dentin slices with 2 mm thickness were prepared from sixty single-rooted human teeth. Dentinal discs were enlarged to achieve 1.3 m...

OBJECTIVE Endothelium-derived nitric oxide (EDNO) has been shown to have vascular, metabolic, and contractile effects in the heart. We evaluated these effects during intracoronary (i.c.) administration of CaCl2 in dogs. METHODS The left anterior descending coronary artery of nine anesthetized, open-chest dogs was perfused at controlled pressure (80 mm Hg) with arterial blood. Coronary blood f...

The postharvest quality of tomato fruit harvested at the pink stage and dipped in 3 different concentrations of CaCl2 for different dip times (30, 20 and 10 minutes) were studied. Tomato fruits dipped in 6% CaCl2 for 30 and 20 minutes retained significantly (P < 0.05) higher level of firmness, titrable acidity and vitamin C than fruits dipped in 2% CaCl2 and the control. The calcium chloride tr...

The effects of temperature and calcium on pectin methylesterase (PME) activity and texture in tomato pericarp material were examined. Heating thin slices of pericarp to temperatures between 50 °C and 75 °C led to the rapid evolution of methanol from the material, indicating an activation of PME. This activity was further stimulated when CaCl2 (up to 2.0% w/v) was added. When applied to half-inc...

Twenty-two Bos indicus type steers were commercially slaughtered, and their carcasses were chilled and processed to determine the effects of injecting calcium chloride (CaCl2) on beef steak palatability and quality traits. Top loin and inside round subprimals were removed from each carcass using industry fabrication procedures. No injection (control) or injection of 200 mM CaCl2 at 5% (wt/wt) w...

The influence of CaCl2 and borax on growth, yield, and quality of tomato was investigated during the years 2009 and 2010. The experiment was laid out with a randomized complete block design. Calcium chloride (0.3% and 0.6%) and borax (0.2% and 0.4%) solutions were applied as foliar sprays either alone or in combination and data were recorded for plant height, branches per plant, flowers per clu...

OBJECTIVES Methylcellulose (MC) is a chemical compound derived from cellulose. MTA mixed with MC reduces setting time and increases plasticity. This study assessed the influence of MC as an anti-washout ingredient and CaCl2 as a setting time accelerator on the physical and biological properties of MTA. MATERIAL AND METHODS Test materials were divided into 3 groups; Group 1(control): distilled...

Platelet-Rich Plasma (PRP) is a low-cost procedure to deliver high concentrations of autologous growth factors (GFs). Platelet activation is a crucial step that might influence the availability of bioactive molecules and therefore tissue healing. Activation of PRP from ten voluntary healthy males was performed by adding 10% of CaCl2, 10% of autologous thrombin, 10% of a mixture of CaCl2 + throm...

The effects of bivalent cations on cytochrome b5 reduction by NADH:cytochrome b5 reductase and NADPH:cytochrome c reductase were studied with the proteinase-solubilized enzymes. Cytochrome b5 reduction by NADH:cytochrome b5 reductase was strongly inhibited by CaCl2 or MgCl2. When 1.2 microM-cytochrome b5 was used, the concentrations of CaCl2 and MgCl2 required for 50% inhibition (I50) were 8 an...
