Rev. bras. cir. plást; 31 (4), 2016
Introduction: Prevention of infection in burned patients poses great challenges such as infection, which constitutes the most common cause of mortality after burn injury. An analysis of burned patients younger than 20 years-old was performed prospectively to identify the incidence of nosocomial infection...

Cloning and purification of the first termicin-like peptide from the cockroach Eupolyphaga sinensis

Abstract Background Termicin is an antimicrobial peptide with six cysteines forming three disulfide bridges that was firstly isolated from the salivary glands and hemocytes of the termite Pseudacanthotermes spiniger. In contrast to many broad-spectrum antimicrobial peptides, termicin is most active again...

Estudo transversal do perfil das infecções congênitas atendidas entre 2012 e 2014 em um centro de referência em Belo Horizonte, Minas Gerais
Cross-sectional study of clinical and laboratorial aspects of congenital infections attended at a reference Center in Belo Horizonte, MG, 2012-2014

Rev. méd. Minas Gerais; 26 (supl. 2), 2016
Introdução: as infecções congênitas são resultantes da transmissão vertical de microrganismos de gestantes infectadas para seus conceptos. Apesar dessas infecções, em geral, cursarem com pouca ou nenhuma manifestação clínica nas gestantes, a infecção fetal pode trazer morbimortalidade perin...

Tissue characterization following revascularization of immature dog teeth using different disinfection pastes

Braz. oral res. (Online); 30 (1), 2016
Abstract Revascularization of immature teeth with necrotic pulps traditionally involves the use of triple antibiotic paste, which may sometimes lead to undesirable complications. The objective of this study was to assess tissue repair in immature dog teeth with apical periodontitis subjected to revascula...

Antimicrobial activity and substantivity of Uncaria tomentosa in infected root canal dentin

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to analyze the antimicrobial activity and substantivity of Uncaria tomentosa Willd DC (cat's claw, CC) in root dentin contaminated with Enterococcus faecalis. Forty-eight human premolars were contaminated with E. faecalis (ATCC 29212) and randomly divided into four grou...

Synthesis and antimicrobial evaluation of two peptide LyeTx I derivatives modified with the chelating agent HYNIC for radiolabeling with technetium-99m

Background Current diagnostic methods and imaging techniques are not able to differentiate septic and aseptic inflammation. Thus, reliable methods are sought to provide this distinction and scintigraphic imaging is an interesting option, since it is based on physiological changes. In this context, radio...

Suscetibilidade antimicrobiana de bactérias ocorrentes em úlceras crônicas aos extratos brutos de Prosopis juliflora

Úlceras crônicas são suscetíveis à infecção devido à perda estéril da função de barreira inata da pele e dos anexos cutâneos, facilitando o desenvolvimento de comunidades microbianas. O objetivo do estudo foi investigar a suscetibilidade de bactérias associadas a úlceras crônicas aos extra...

Triagem fitoquímica, análise antimicrobiana e citotóxica e dos extratos das plantas: schinus terebinthifolia, maytenus ilicifolia reissek, tabebuia avellanedae, anadenanthera colubrina (Bell. ) Brenan

O reino vegetal oferece maior variedade de substâncias potencialmente úteis nas enfermidades humanas, especialmente aquelas causadas por micro-organismos. Um dos maiores problemas de Saúde Pública enfrentado nos últimos anos é o agravamento da resistência bacteriana e isto se tornou mais grave com...

Silver nanoparticles incorporated into nanostructured biopolymer membranes produced by electrospinning: a study of antimicrobial activity

Braz. j. pharm. sci; 51 (4), 2015
abstract This study examines the antimicrobial activity of silver nanoparticles incorporated into nanostructured membranes made of cellulose acetate (CA) and blends of chitosan/poly-(ethylene oxide, CTS/PEO) and prepared by electrospinning. The formation of chemically synthesized Ag nanoparticles (AgNPs)...
