A progressive reduction in the size of rat metallothionein-1 mRNA following induction by copper chloride or dexamethasone was demonstrated on RNA blots, and was shown to be due to shortening of the poly(A)-tail. The rate of poly(A) removal was the same in rat liver and kidney following copper chloride induction, in rat liver following dexamethasone induction, and in mouse liver following copper...

BACKGROUND Contamination of dentin with hemostatic agents might exert a deleterious effect on adhesive procedures on dentin. The present study was undertaken to investigate the effect of aluminum chloride hemostatic agent on marginal gaps in Cl V giomer restorations. MATERIAL AND METHODS Fifty sound bovine permanent incisors were selected for the purpose of this in vitro study and Cl V caviti...

AIM This study evaluated the effect of three different contamination removal methods on bond strength of one-step self-etching adhesive to dentin contaminated with an aluminum chloride hemostatic agent. MATERIALS AND METHODS One hundred noncarious adult molars were used in this study; 2-mm-thick dentin disks were prepared and randomly assigned to 5 groups (n = 20). Group I: control; group II:...

OBJECTIVES/HYPOTHESIS To determine the ototoxic potential of aluminum acetate (0.5%)/benzethonium chloride (0.03%) otic solution in the chinchilla animal model. STUDY DESIGN A randomized, prospective, controlled study was conducted in the chinchilla animal model. METHODS Fourteen female chinchillas were used. After an incision was made in each tympanic membrane, baseline auditory brainstem ...

Background: Coagulation is a treatment procedure for metalworking fluids (MWFs). This study aimed to optimize coagulation using four coagulants and compare the results. Methods: In this research, the outputs of a coagulation procedure in chemical oxygen demand (COD) removal, turbidity, and the release of oil were investigated using four coagulants, ferric chloride (FeCl3), ferric sulfate (Fe2(...

Working on sludge with electrochemical oxidation is beneficial to promote the subsequent recessive growth of microorganisms in sludge. To achieve on-site reduction, this study combined anoxic/oxic (A/O) process based cell lysis-cryptic theory by determining experimental conditions and mechanism lysis. The reduction effluent treatment practical operation were studied. results showed that cumulat...
