This study investigated the effect of a caries-detecting solution on the tensile bond strength (TBS) to sound bovine dentin--which was either rinsed thoroughly of or contaminated with the caries-detecting solution. Caries Detector (1.0% acid red in propylene glycol) was applied on flat dentin surfaces for 10 seconds, rinsed, and dried with syringe air. In another group, Caries Detector was not ...

Frothers havea profoundeffectonbubble size and also flotation efficiency. In present study the effect of type and dosage of frothers on the flotation response of coarse particles of quartz was investigated.  Therefore, flotation response of coarse particles using frothers such as MIBC, pine oil, poly propylene glycol with concentration of 0, 25, 50 and 75...

introduction: the aim of this study was to evaluate the effect of adding propylene glycol (pg) to mineral trioxide aggregate (mta) liquid with volume ratio of 20% on the compressive strength (cs) of mta in two time periods (4 and 21 days) after mixing. methods and materials: four groups of steel cylinders ( n =15) with an internal diameter of 3 and a height of 6 mm were prepared and mta (groups...

The research was carried out on 2 groups of dairy cows 30 heads the farm with formation technological according to timing calving and milking unit individual accounting milk yield. Cows experimental group in period two weeks before for months after were added diet, respectively, 150 300 ml / head day energy feed based propylene glycol glycerin a complex enzymes cellulase, xylase, beta-gluconase...

Fish oocytes have not been cryopreserved successfully, probably because it is difficult to prevent intracellular ice from forming. Previously, we have shown in medaka that immature oocytes are more suitable for cryopreservation than mature oocytes or embryos, in terms of permeability. We have also shown in immature medaka oocytes that the exogenous expression of aquaporin 3 (AQP3), a water/cryo...

The effect of i.v. propylene glycol in doses of 160-800 mg kg-1 on heart rate, arterial pressure and efferent sympathetic activity were observed in anaesthetized paralysed, artificially ventilated dogs. Within 3-5 s of the commencement of the injection of propylene glycol there was an immediate mean decrease in heart rate of 22.7 and 72.1 beat min-1 and in arterial pressure of 27.2 and 58.8 mm ...
