1. Virulence genes and genetic relationship of L. monocytogenes isolated from human and food sources in Brazil
ABSTRACT The herein presented assay provided a bacteriological and molecular characterization of 100 samples of L. monocytogenes isolated from human (43) and food (57) sources, from several regions of Brazil, and collected between 1975 and 2013. Antigenic characterization defined 49% of serotype 4b samples, followed by 28% of serotype 1/2b, 14% of serotype 1

2. Analise comparativa da eficácia do método imuno-histoquímico (d2-40 e cd34) e coloração de rotina (he) para detecção de invação vascular linfática e sanguinea no carcinoma gástrico
BACKGROUND: Worldwide, gastric carcinoma (GC) is the second largest cause of cancer-related death. The TNM staging system for GC is widely used and it provides important prognostic information, especially with regards to the lymph node status. The presence of lymphatic invasion (LVI) detected on the primary tumor is the strongest risk factor for lymph node m

3. VARIABLE-RATE NITROGEN FERTILIZATION WITH N-SENSOR IN MAIZE AND WHEAT / ADUBAÇÃO NITROGENADA À TAXA VARIADA COM O N-SENSOR NAS CULTURAS DO MILHO E TRIGO
Most tropical and subtropical soils present insufficient availability of nitrogen (N) to meet the demand of maize and wheat in order to obtain high yields. The N in plants can be evaluated through the use of sensors of active optical spectrometry, on which stands the N-Sensor, equipment able to determine the N rate to be applied in coverage in real-time. The

4. Sintese de indutancia negativa para aplicação serie em redes de energia eletrica / Negative inductance synthesis for series applications on the electrical network
Nesta tese é introduzida uma nova estratégia de controle que permite a síntese de indutâncias negativas para realização da compensação série de linhas de transmissão. O método, que é baseado na estratégia SDR (Síntese Direta de Reatâncias), opera com realimentação de estados e requer a medição de variáveis locais. Em relação aos método

5. Detection of Metarhizium anisopliae var. anisopliae within infected sugarcane borer Diatraea saccharalis (Lepidoptera, Pyralidae) using specific primers
In order to construct specific primers for the detection and identification of the entomopathogenic fungus Metarhizium within infected sugarcane borer (Diatraea saccharalis) larvae we analyzed the ITS1 -5.8S- ITS2 rDNA regions of strains and varieties of M. anisopliae, M. album and M. flavoviride. The PCR amplification of these regions yielded a unique fragm

6. Detecção e identificação de Metarhizium anisopliae em larvas de Diatraea saccharalis por Primers específicos. / Detection and identification of metarhizium anisopliae within infected sugarcane borer diatraea saccharalis larvae using specific primers.
A região espaçadora ITS rDNA tem sido utilizada como uma importante ferramenta molecular para a identificação de fungos. Neste estudo a região ITS1 - 5.8S - ITS2 foi analisada em diferentes espécies do fungo entomopatogênico Metarhizium incluindo M. anisopliae, M. album e M. flavoviride com o objetivo de se construir primers específicos para a detec�

7. Sintese e aplicações de indutancias negativas
This doctorate dissertation presents methods for emulating negative inductance, as well as their applications and stability analysis. Such non-natural behavior is analyzed based on mathematical modeling, circuit simulations and experimental results. Previously presented synthesis methods, the VAPAR and the BVI are described, and a new strategy, called SDR is

8. Quorum-Sensing Signals and Quorum-Sensing Genes in Burkholderia vietnamiensis
Acyl-homoserine lactone (acyl-HSL) quorum sensing is common to many Proteobacteria including a clinical isolate of Burkholderia cepacia. The B. cepacia isolate produces low levels of octanoyl-HSL. We have examined an environmental isolate of Burkholderia vietnamiensis. This isolate produced several acyl-HSLs. The most abundant species was decanoyl-HSL. Decan

9. Evidence for Production of a New Lantibiotic (Butyrivibriocin OR79A) by the Ruminal Anaerobe Butyrivibrio fibrisolvens OR79: Characterization of the Structural Gene Encoding Butyrivibriocin OR79A†
The ruminal anaerobe Butyrivibrio fibrisolvens OR79 produces a bacteriocin-like activity demonstrating a very broad spectrum of activity. An inhibitor was isolated from spent culture fluid by a combination of ammonium sulfate and acidic precipitations, reverse-phase chromatography, and high-resolution gel filtration. N-terminal analysis of the isolated inhib

10. Transcriptional Organization of the Erythromycin Biosynthetic Gene Cluster of Saccharopolyspora erythraea
The transcriptional organization of the erythromycin biosynthetic gene (ery) cluster of Saccharopolyspora erythraea has been examined by a variety of methods, including S1 nuclease protection assays, Northern blotting, Western blotting, and bioconversion analysis of erythromycin intermediates. The analysis was facilitated by the construction of novel mutants

11. Distribution of Quorum-Sensing Genes in the Burkholderia cepacia Complex
The distribution of quorum-sensing genes among strains from seven genomovars of the Burkholderia cepacia complex was examined by PCR. cepR and cepI were amplified from B. cepacia genomovars I and III, B. stabilis, and B. vietnamiensis. cepR was also amplified from B. multivorans and B. cepacia genomovar VI. bviIR were amplified from B. vietnamiensis. All gen
