3. Investigação sobre compostos voláteis de espécies de Baccharis nativas do Rio Grande do Sul
The species of Baccharis spp. (Compositae) are an important source of research to investigation new active ingredients for medicinal natural products. Thus, this work presents a proposition of research on volatile compounds of three native species of Baccharis (Baccharis anomala DC, Baccharis dentata (Vell) G. M. Barroso and Baccharis uncinella DC) collected

4. Effect of repeated immersion solution cycles on the color stability of denture tooth acrylic resins
OBJECTIVE: Chemical solutions have been widely used for disinfection of dentures, but their effect on color stability of denture tooth acrylic resins after repeated procedures is still unclear. The aim of this in vitro study was to evaluate whether repeated cycles of chemical disinfectants affected the color stability of two denture tooth acrylic resins. MAT

5. Micobactérias de crescimento rápido de importância médica no Brasil: eficácia antimicrobiana de desinfetantes e sistema de esterilização por plasma / Rapidly growing mycobacteria of medical importance in Brazil: antimicrobial efficacy of disinfectants and plasma sterilization system
Práticas inadequadas de descontaminação, desinfecção e esterilização de materiais médico-hospitalares têm propiciado o surgimento de inúmeros surtos de infecções por \ Micobactérias de Crescimento Rápido\ (MCR), em todo o Brasil. Entre os anos de 2000 a 2008 foram relatados mais de 2000 casos confirmados de infecções por MCR, sendo que os pro

6. Evaluation of alternative methods for the disinfection of toothbrushes
The aim of this study was to evaluate alternative methods for the disinfection of toothbrushes considering that most of the previously proposed methods are expensive and cannot be easily implemented. Two-hundred toothbrushes with standardized dimensions and bristles were included in the study. The toothbrushes were divided into 20 experimental groups (n = 10

7. Antimicrobial efficacy of chemical disinfectants on contaminated full metal crowns
Restaurações protéticas provadas na cavidade bucal dos pacientes são fontes potenciais de infecção. Para evitar infecção cruzada, protocolos de controle de infecção devem ser estabelecidos no consultório e laboratório odontológicos. Este estudo avaliou a eficácia antimicrobiana de desinfetantes químicos em coroas metálicas contaminadas com mi

8. Evaluation of the viability of sporulated oocysts of Neospora caninum under different temperature and disinfectants treatments / Avaliação da viabilidade de oocistos esporulados de Neospora caninum a diferentes condições de temperatura e ação de desinfetantes
Neospora caninum is an Apicomplexan parasite that causes neuromuscular disorders in dogs and abortion in cattle. Dogs and coyotes are the only species identified as definitive hosts. The sexual phase of the N. caninum life cycle occurs within the host, and results in the shedding of oocysts in the feces that will sporulate in the environment and become infec

9. Physical-chemical characterization of pine oil samples and study on surfactants systems action in antimicrobial activity of active phenolic / Caracterização físico-química de amostras de óleo de pinho e estudo da ação de sistemas tensoativos na atividade antimicrobiana de ativos fenólicos
This work aims at characterizing commercial samples of pine oil with a view at identifying other components that present antimicrobial action besides its o -terpineol. It also aims at evaluating how three different surfactants influence the antimicrobial action of the o-phenyl-phenol, of the o-benzyl-p-chlorophenol and p-chloro-m-cresol. The selected surfact

10. Avaliação da atividade micobactericida de desinfetantes químicos utilizando a técnica de cultivo em camada de ágar Middlebrook 7H11 / Evaluation of mycobactericidal activity of chemical disinfectants using the Middlebrook 7H11 agar medium technique
The mycobactericidal activity of five chemical disinfectants was evaluated against a strain of Mycobacterium bovis isolated from a goat, typified by PCR (polymerase chain reaction) and with 32 days of growth in the Stonebrink medium. The disinfectants were tested using the modified thin layer Middlebrook 7H11 cultivation technique and it was compared to the

11. COOLING WATER TREATMENT USING HYDROGEN PEROXIDE / TRATAMENTO DE ÁGUAS DE RESFRIAMENTO COM PERÓXIDO DE HIDROGÊNIO
Cooling water treatment generally is made with the addition of chlorine, although it´s application has some disadvantages. There is an active development in Brazil and other countries to use alternative chemical disinfectants in place of chlorine, such as hydrogen peroxide, a powerful oxidant which is known for its high biocidal efficiency. The aim of this

12. Susceptibility of clinical isolates of multiresistant Pseudomonas aeruginosa to a hospital disinfectant and molecular typing
The aim of this study was to evaluate the susceptibility of 35 resistant Pseudomonas aeruginosa clinical isolates to a quaternary ammonium hospital disinfectant. The methodology was the AOAC Use-Dilution Test, with disinfectant at its use-concentration. In addition, the chromosomal DNA profile of the isolates were determined by macro-restriction pulsed field
