1. Influence of 2% chlorhexidine on pH, calcium release and setting time of a resinous MTA-based root-end filling material
The addition of chlorhexidine (CHX) to a resinous experimental Mineral Trioxide Aggregate (E-MTA) based root-end filling material is an alternative to boost its antimicrobial activity. However, the influence of chlorhexidine on the properties of this material is unclear. The aim of this study was to evaluate the influence of 2% chlorhexidine on the pH, calci

2. Compensador série de tensão em onda quadrada para mitigação de afundamentos de tensão
Compensadores Série de Tensão (CST) são utilizados para mitigação de fenômenos de qualidade da energia elétrica relacionados a distúrbios na tensão. Os mais conhecidos en-TM tre os CSTs são o DVR (Dynamic Voltage Restorer) e o TM DySC (Dynamic Sag Corrector), utilizados para proteção de cargas elétricas sensíveis a afundamentos de tensão. A te

3. EMI conduzida gerada por conversores estáticos aplicados à correção do fator de potência
Este trabalho investiga a interferência eletromagnética (EMI) conduzida gerada por conversores estáticos aplicados a correção do fator de potência. As topologias discutidas neste artigo são os conversores boost, boost intercalado e dual boost. Uma análise do comportamento dos ruídos conduzidos de modo diferencial e de modo comum nos conversores são

4. Conversores CC-CC elevadores de tensão, não isolados, com ganhos estáticos elevados / Step-up, non-insulated, high-gain Dc-DC converters
The DC-DC converters have important applications in the electric energy generation using renewable energy sources and in the electric vehicles. In those applications, it is often required that the converter operates with high voltage gain. This work investigates some non-insulated topologies of DC-DC converters that can be used when high voltage gain is nece

5. ANÁLISE COMPARATIVA DE CONVERSORES MONOFÁSICOS APLICADOS A CORREÇÃO DE FATOR DE POTÊNCIA
Esse trabalho apresenta um estudo e uma análise comparativa de conversores monofásicos aplicados i correção de fator de potência que estejam de acordo com as normas internacionais IEC 61000-3-4 (limitação de harmônicos) e CISPR 22 (limitação dos níveis de interferência eletromagnética) para aplicações de alta potência. Os conversores estudado

6. Recombinant rabies virus as potential live-viral vaccines for HIV-1
Recombinant, replication-competent rabies virus (RV) vaccine strain-based vectors were developed expressing HIV type I (HIV-1) envelope glycoprotein (gp160) from both a laboratory-adapted (CXCR4-tropic) and a primary (dual-tropic) HIV-1 isolate. An additional transcription stop/start unit within the RV genome was used to express HIV-1 gp160 in addition to th

7. Human Immunodeficiency Virus Induces a Dual Regulation of Bcl-2, Resulting in Persistent Infection of CD4+ T- or Monocytic Cell Lines
This work aims at characterizing the interplay between human immunodeficiency virus type 1 (HIV-1) and the antiapoptotic cellular protein Bcl-2 responsible for a persistent infection in lymphoblastoid T (J.Jhan) or monocytic (U937) cells. We report that the kinetics of Bcl-2 protein level during the establishment of a chronic infection is biphasic, character

8. Viral targeting of hematopoietic progenitors and inhibition of DC maturation as a dual strategy for immune subversion
DCs play a pivotal role in bringing forth innate and adaptive immune responses. Viruses can specifically target DCs, rendering them ineffective in stimulating T cells, which can ultimately lead to immunosuppression. In the present study we have identified several potential mechanisms by which lymphocytic choriomeningitis virus (LCMV) induces immunosuppressio

9. CD8+ T cell responses against a dominant cryptic HLA-A2 epitope after NY-ESO-1 peptide immunization of cancer patients
NY-ESO-1 is a germ cell antigen aberrantly expressed in different tumor types that elicits strong humoral and cellular immune responses in cancer patients. Monitoring spontaneous CD8+ T cell responses against NY-ESO-1 peptides 157–165 (S9C) and 157–167 (S11L) in a series of HLA-A2+ cancer patients showed that these two peptides had overlapping antigenic
