The purpose of this study was to evaluate the effectiveness of various chemical disinfectants in decontamination of gutta-percha (GP) cones contaminated with Bacillus subtilis spores. Sodium hypochlorite solution (4%), glutaraldehyde solution (2%), povidone-iodine solution (5%), and savlon solutions were compared for effectiveness in sterilizing gutta-percha cones contaminated with Bacillus sub...

BACKGROUND To determine the efficacy of different antiseptic solutions (Control group (I), Antibiotic solution (II), Chlorhexidine 0.4% (III), and povidone - iodine 10% (IV)) in sterilizing contaminated osteochondral plugs. METHODS Under sterile conditions, the femoral head and condyles of 20 rabbits were removed and cut into equal osteochondral pieces. A total of 200 osteochondral specimens ...

Babenyshev and Martins proved that two hidden multi-sorted deductive systems are deductively equivalent if and only if there exists an isomorphism between their corresponding lattices of theories that commutes with substitutions. We show that the π-institutions corresponding to the hidden multi-sorted deductive systems studied by Babenyshev and Martins satisfy the multi-term condition of Gil-Fé...

To eliminate the use of chlorinated hydrocarbons, we have improved the method for the flow-injection (FI) determination of iodine based on the chemiluminescence reaction of iodine with luminol in a chloroform-free reversed micellar medium of the surfactant cetyltrimethylammonium chloride (CTAC) using a mixture of 1-hexanol-cyclohexane as a bulk solvent. The FI procedure used simply involves the...

The activity per unit mass of an iodine-131 solution was absolutely standardized by both the 4πβ-γ coincidence method and the 4πγ counting technique. The calibrated solution was used to prepare point sources after a preliminary deposit of AgNO3 to prevent the loss of volatile iodine. Relative and absolute photon emission intensities of 15 sgamma-rays and those of the two K X-rays of xenon were ...

A spectrophotometric study concerning the interactoin between iodine and bromine with tetrabutylammonium iodide (TBAI), tetrabutyl- ammonium bromide (TBABr) and cryptand 222 (C222) has been performed in dichloromethane solution at 25°C. The results are indicative of the formation of TBA+X3- and  C222X+X3-  t...

b-cyclodextrin glucosyl transferase (b-cgtase) hydrolyses starch to produce b-cyclodextrin by transglycosylation (cyclization) activity. the conventional method for detection of b-cgtase activity is based on detecting starch hydrolysis by iodine staining. this method reveals all amylolytic enzymes, but can not discriminate them. in the present study, we introduce a new method for specific detec...
