1. Impact of Single versus Double Clamp Technique on Blood Lactate Levels and Postoperative Complications in Coronary Artery Bypass Surgery
Abstract Introduction: Cardiopulmonary bypass (CPB) is associated with hyperlactatemia, which leads to adverse clinical outcomes. No study has examined the effect of different clamping techniques on postoperative hyperlactatemia (PHL). Thus, we aimed to evaluate the impact of two different techniques on PHL and the clinical outcomes in patients undergoing i

2. Avaliação da qualidade de amostras comerciais de leite de janaguba (Himatanthus drasticus (Mart.) Plumel) em Fortaleza – Ceará
RESUMO Os fitoterápicos à base de leite de janaguba (Himatanthus drasticus (Mart.) Plumel), usados para o tratamento de câncer, úlcera gástrica e outras doenças, são muito vendidos em mercados públicos de Fortaleza (CE). No entanto, registros mencionam que é comum a troca deste leite por látex de mangabeira (Hancornia speciosa Gomes). O trabalho ob

4. Effects of bleaching agents of high concentration for treatment in office in microhardness, morphology and chemical composition of human enamel / Efeitos de agentes clareadores de alta concentração para tratamento em consultorio na microdureza, morfologia e composição quimica do esmalte humano
Several studies have been concerned with the adverse effects produced by home applied and in-office bleaching treatments. The aim of this study is to evaluate the effects of highconcentrated bleaching agents (35% hydrogen peroxide) on human enamel microhardness, chemical and structural composition. Sixty and five human third molars human were used. Two ename

6. Characterization of Interactions between the Transcriptional Repressor PhlF and Its Binding Site at the phlA Promoter in Pseudomonas fluorescens F113
The phlACBD genes responsible for the biosynthesis of the antifungal metabolite 2,4-diacetylphloroglucinol (PHL) by the biocontrol strain Pseudomonas fluorescens F113 are regulated at the transcriptional level by the pathway-specific repressor PhlF. Strong evidence suggests that this regulation occurs mainly in the early logarithmic phase of growth. First, t

7. Identification and Characterization of a Gene Cluster for Synthesis of the Polyketide Antibiotic 2,4-Diacetylphloroglucinol from Pseudomonas fluorescens Q2-87
The polyketide metabolite 2,4-diacetylphloroglucinol (2,4-DAPG) is produced by many strains of fluorescent Pseudomonas spp. with biocontrol activity against soilborne fungal plant pathogens. Genes required for 2,4-DAPG synthesis by P. fluorescens Q2-87 are encoded by a 6.5-kb fragment of genomic DNA that can transfer production of 2,4-DAPG to 2,4-DAPG-nonpro

8. Autoinduction of 2,4-Diacetylphloroglucinol Biosynthesis in the Biocontrol Agent Pseudomonas fluorescens CHA0 and Repression by the Bacterial Metabolites Salicylate and Pyoluteorin†
The antimicrobial metabolite 2,4-diacetylphloroglucinol (2,4-DAPG) contributes to the capacity of Pseudomonas fluorescens strain CHA0 to control plant diseases caused by soilborne pathogens. A 2,4-DAPG-negative Tn5 insertion mutant of strain CHA0 was isolated, and the nucleotide sequence of the 4-kb genomic DNA region adjacent to the Tn5 insertion site was d

9. Fusaric Acid-Producing Strains of Fusarium oxysporum Alter 2,4-Diacetylphloroglucinol Biosynthetic Gene Expression in Pseudomonas fluorescens CHA0 In Vitro and in the Rhizosphere of Wheat
The phytotoxic pathogenicity factor fusaric acid (FA) represses the production of 2,4-diacetylphloroglucinol (DAPG), a key factor in the antimicrobial activity of the biocontrol strain Pseudomonas fluorescens CHA0. FA production by 12 Fusarium oxysporum strains varied substantially. We measured the effect of FA production on expression of the phlACBDE biosyn

10. Conservation of the 2,4-diacetylphloroglucinol biosynthesis locus among fluorescent Pseudomonas strains from diverse geographic locations.
The broad-spectrum antibiotic 2,4-diacetylphloroglucinol (PHL) is a major determinant in the biological control of a range of plant pathogens by many fluorescent Pseudomonas spp. A 4.8-kb chromosomal DNA region from Pseudomonas fluorescens Q2-87, carrying PHL biosynthetic genes, was used as a probe to determine if the PHL biosynthetic locus is conserved with

11. The PhlA Hemolysin from the Entomopathogenic Bacterium Photorhabdus luminescens Belongs to the Two-Partner Secretion Family of Hemolysins
Photorhabdus is an entomopathogenic bacterium symbiotically associated with nematodes of the family Heterorhabditidae. Bacterial hemolysins found in numerous pathogenic bacteria are often virulence factors. We describe here the nucleotide sequence and the molecular characterization of the Photorhabdus luminescens phlBA operon, a locus encoding a hemolysin wh

12. Assessment of Genotypic Diversity of Antibiotic-Producing Pseudomonas Species in the Rhizosphere by Denaturing Gradient Gel Electrophoresis
The genotypic diversity of antibiotic-producing Pseudomonas spp. provides an enormous resource for identifying strains that are highly rhizosphere competent and superior for biological control of plant diseases. In this study, a simple and rapid method was developed to determine the presence and genotypic diversity of 2,4-diacetylphloroglucinol (DAPG)-produc
