A Protocol to Perform Systemic Lipopolysacharide (LPS) Challenge in Rats

Odovtos (En línea); 21 (1), 2019
Abstract 19. Lipopolysaccharide (LPS) is a component of the outer membrane of Gram-negative bacteria. In animals, intraperitoneal administration of LPS, stimulates innate immunity and the production of proinflammatory cytokines. LPS provides an inflammatory stimulus that activates the neuroimmune and neu...

Owlet moths (Lepidoptera: Noctuoidea) associated with Bt and non- Bt soybean in the brazilian savanna

Braz. j. biol; 79 (2), 2019
Abstract The use of GMO expressing Bt toxin in soybean production has increased significantly in the last years in Brazil in order to manage the damage caused by lepidopteran pests. In this study, we compared the richness and abundance of owlet moths (Noctuoidea) associated with Bt and non-Bt soybean. W...

Correlation between volume of root canal, cultivable bacteria, bacterial complexes and endotoxins in primary infection

Braz. dent. j; 30 (2), 2019
Abstract This clinical study was conducted to correlate the levels of endotoxins and culturable bacteria found in primary endodontic infection (PEI) with the volume of root canal determined by using Cone Beam Computed Tomography (CBCT); and to evaluate the bacterial diversity correlating with clinical fe...

Redução de bactérias cultiváveis, lipopolissacarídeos e colagenase/mmp-8 no tratamento endodôntico associado à ativação ultrassônica na infecção endodôntica primária: estudo clínico randomizado

O objetivo desse estudo clínico randomizado foi avaliar em dentes com infecção endodôntica primária (IEP) os microrganismos anaeróbios cultiváveis (UFC/mL), níveis de endotoxinas (LPS) (EU/mL) e colagenase/MMP-8 da região periapical antes e durante o tratamento endodôntico utilizando diferentes...

Aplicabilidade de métodos alternativos no monitoramento da qualidade microbiológica da água tratada para diálise

A fim de garantir a qualidade final de produtos os laboratórios de análise microbiológica fornecem dados sobre a qualidade dos mesmos em todas as suas etapas de produção. A crescente preocupação com a saúde dos pacientes conduz à busca de métodos que forneçam resultados precisos e rápidos, po...

Comparison of two rotary systems in bacteria/lps removal from endodontic infections: randomized clinical trial

Abstract: This clinical study compared the effectiveness of two rotary systems: HyFlex CM (Coltene-Whaledent, Altstetten, Switzerland) and ProTaper Next (Dentsply Sirona, Ballaigues, Switzerland) on the removal of cultivable bacteria and endotoxins from primarily infected root canals. This study was desi...

Etiologic role of root canal infection in apical periodontitis and its relationship with clinical symptomatology

Braz. oral res. (Online); 32 (supl.1), 2018
Abstract: Evidence shows the polymicrobial etiology of endodontic infections, in which bacteria and their products are the main agents for the development, progression, and dissemination of apical periodontitis. Microbial factors in necrotic root canals (e.g., endotoxin) may spread into apical tissue, ev...

Successful and failed mini-implants: microbiological evaluation and quantification of bacterial endotoxin

J. appl. oral sci; 26 (), 2018
Abstract Objectives Using two groups of mini-implants (successful and failed) the objectives of this in vivo study were: to evaluate the microbial contamination by the checkerboard DNA-DNA hybridization technique and to quantify the bacterial endotoxin by the limulus amebocyte lysate assay. Material a...

Diversity and distribution of lepidopteran-specific toxin genes in Bacillus thuringiensis strains from Argentina

Rev. argent. microbiol; 49 (3), 2017
A total of 268 Bacillus thuringiensis strains obtained from different sources of Argentina were analyzed to determine the diversity and distribution of the cryl, cry2, cry8, cry9 and vip3A genes encoding for lepidopteran-specific insecticidal proteins. Twin strains were excluded. Ten different profiles w...
