Determination of residual parachloroaniline produced by endodontic treatment after the use of 5% sodium hypochlorite and 2% chlorhexidine combined: an ex-vivo study

ABSTRACT: Aim: The objective of this work was to determine the concentrations of irrigating solutions and the residual content of parachloroaniline (PCA) formed after endodontic irrigation, using 5% NaOCl, 0.9% NaCl, 10% EDTA and 2% CHX 2%. Methodology Twenty premolars were used and 13 samples were col...

Development of a propidium monoazide-polymerase chain reaction assay for detection of viable Lactobacillus brevis in beer

Braz. j. microbiol; 48 (4), 2017
ABSTRACT The spoilage of beer by bacteria is of great concern to the brewer as this can lead to turbidity and abnormal flavors. The polymerase chain reaction (PCR) method for detection of beer-spoilage bacteria is highly specific and provides results much faster than traditional microbiology techniques. ...

Variation analysis of bacterial polyhydroxyalkanoates production using saturated and unsaturated hydrocarbons

Braz. j. microbiol; 48 (4), 2017
ABSTRACT Polyhydroxyalkanoates (PHA) are efficient, renewable and environment friendly polymeric esters. These polymers are synthesized by a variety of microbes under stress conditions. This study was carried out to check the suitability of waste frying oil in comparison to other oils for economical biop...

Promotion of iron nutrition and growth on peanut by Paenibacillus illinoisensis and Bacillus sp. strains in calcareous soil

Braz. j. microbiol; 48 (4), 2017
ABSTRACT This study aimed to explore the effects of two siderophore-producing bacterial strains on iron absorption and plant growth of peanut in calcareous soil. Two siderophore-producing bacterial strains, namely, YZ29 and DZ13, isolated from the rhizosphere soil of peanut, were identified as Paenibacil...

Isolation and molecular characterization of Thraustochytrium strain isolated from Antarctic Peninsula and its biotechnological potential in the production of fatty acids

Braz. j. microbiol; 48 (4), 2017
ABSTRACT Thraustochytrids are unicellular protists belonging to the Labyrinthulomycetes class, which are characterized by the presence of a high lipid content that could replace conventional fatty acids. They show a wide geographic distribution, however their diversity in the Antarctic Region is rather s...

Characterization of dioxygenases and biosurfactants produced by crude oil degrading soil bacteria

Braz. j. microbiol; 48 (4), 2017
ABSTRACT Role of microbes in bioremediation of oil spills has become inevitable owing to their eco friendly nature. This study focused on the isolation and characterization of bacterial strains with superior oil degrading potential from crude-oil contaminated soil. Three such bacterial strains were selec...

Localization and identification of tyrosine phosphorylated proteins in adult Sprague-Dawley rat testis

Int. j. morphol; 35 (4), 2017
SUMMARY: Spermatogenesis is a major process in testis occurring from puberty through life span of males. The tyrosine phosphorylation is assumed to play roles in spermatogenesis because this process is important for cell proliferations, divisions, and differentiations. However, the localizations and iden...

Parâmetros citológicos e bioquímicos do líquido cefalorraquidiano coletado de bovinos sadios em dois momentos, com intervalo de 96 horas

A análise do líquido cefalorraquidiano (LCR) é uma importante ferramenta no diagnóstico das doenças neurológicas dos bovinos. A coleta do LCR em diferentes momentos facilita o monitoramento do quadro clínico e/ou a avaliação da eficácia de tratamentos estabelecidos. Todavia, os efeitos de colet...

Effect of different commercial fat sources on brain, liver and blood lipid profiles of rats in growth phase

Acta cir. bras; 32 (12), 2017
Abstract Purpose: To investigate the fatty acid content of different fat sources and evaluate the effect of them on plasma and hepatic lipids and on the fatty acid profile of the brain tissue of Wistar rats. Methods: Thirty male albino Wistar rats received for 59 days, the following diets: diet added...

Crab shell extract improves serum biochemical markers and histological changes of pancreas in diabetic rats

Int. j. morphol; 35 (4), 2017
SUMMARY: Diabetes mellitus is a common metabolic disease. There are many natural agents available to control and treat diabetes. Crab shell extract has antioxidant properties. The aim of present study was to investigate the effect of crab shell hydroalcoholic extract on blood glucose, liver enzymes, nitr...
