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...

Effects of ouabain, CaCl2 and verapamil on the frequency-force relationship (FFR) were investigated in the isolated, blood-perfused dog atrial muscle preparation. When ouabain (3 and 10 micrograms) or CaCl2 (0.5, 1 and 2 mg/min) was given into the sinus node artery, the contractile force of the atrial muscle, driven at a constant pacing rate of 2 Hz, increased dose-dependently. Verapamil (1 and...

The effects of changed ionic environments on the canine taste responses to sugars were examined by recording the activity of the chorda tympani nerve. a) The responses to various sugars were greatly enhanced by the presence of salts having monovalent cations such as Na+, K+, choline+, or Tris+. The responses to sugars were suppressed by high concentrations of salts. (b) The presence of 100 mM N...

Ovine carcasses were arterially infused with a volume equal to 10% of the live weight after electrical stimulation. The infusion solutions contained .075 M, .15 M or .3 M calcium chloride. Results indicated that .3 M calcium chloride treatment was the most effective concentration of CaCl2 to reduce the shear force value measured at 24 h postmortem. To examine the contribution of ionic strength ...

Calcium alginate membrane has great potential for membrane separation technology. The polymer frameworks of the membrane were successfully regulated by the mass fraction of homopolymeric blocks of -L-guluronic acid (FGG) in the entire molecular chain of alginate and the additive CaCl2 as a cross-linker. The mechanical strength can be controlled by regulated the FGG and CaCl2 concentration. Sele...

The benefits of calcium applications pre and postharvest on fruit storage ability have been mentioned in the bibliography. It was objective of this work to study the effect of calcium preharvest application in two different forms and calcium chloride application postharvest on ‘Hayward’ kiwifruit storage ability. Kiwifruit vines were sprayed with 0.03% CaCl2 or 0.03% CaO at one, three and four ...

γ-Aminobutyric acid (GABA) can accumulate in apple fruit response to stress, but little is known about the responses of GABA treatments. The hypothesis that would inhibit physiological disorder development ‘Honeycrisp’ apples has been tested a three-year study. In 2015, trees were sprayed with 40 mM 2 and 4 weeks before harvest, harvested stored at 0.5 °C, chilling injury-inducing temperature, ...
