1. Soil microbial biomass and enzyme activity in six Brazilian oxisols under cropland and native vegetation
ABSTRACT Oxisols are important soils that have been converted from native vegetation to croplands, and can affect soil biological properties such as microbial biomass and enzyme activity. Thus, the aim of this study was to evaluate the changes on soil microbial biomass and enzyme activity when native vegetation (NV) was converted to cropland (CL), such as ma

3. Dendritic cells and their relation to apical peridontitis
Abstract: The purpose of this manuscript was to re-discuss apical periodontitis, apical biofilm, and its possible relationship with dendritic cells (DC). DCs are potent regulators of the immune system and their function is divided into three categories that involve the presentation of antigens: the presentation of antigens and activation of T cells; a not we

4. A biotechnology perspective of fungal proteases
Proteases hydrolyze the peptide bonds of proteins into peptides and amino acids, being found in all living organisms, and are essential for cell growth and differentiation. Proteolytic enzymes have potential application in a wide number of industrial processes such as food, laundry detergent and pharmaceutical. Proteases from microbial sources have dominated

5. Identificação de fatores de transcrição e sinais celulares que regulam a expressão do gene cspC em Caulobacter crescentus. / Identification of transcription factors and cellular signals that regulate cspC gene expression from Caulobacter crescentus.
As proteínas de choque frio pertencem a uma família de proteínas com um domínio altamente conservado, denominado domínio de choque frio (CSD). Estão envolvidas em vários processos celulares, incluindo adaptação a baixas temperaturas, estresse nutricional e fase estacionária. Em C. crescentus, uma α-proteobacteria não pat

6. Atividade e diversidade catabólica da biomassa microbiana do solo alterada pelo uso da terra / Effects of soil land use on microbial activity and catabolic diversity
The increasing demand for food creates environmental problems, mainly due to the removal of native vegetation cover for agriculture expansion in Brazil. These changes in land use leads to changes in the soil organic matter dynamics. The vegetation type also affects the soil biota and, therefore, its change causes modifications in the microbial biomass, as sh

7. Caracterização molecular das subunidades catalítica e regulatória da calcineurina no fungo patogênico Paracoccidioides brasiliensis. / Molecular characterization of catalytic and regulatory subunits of calcineurina in the pathogenic fungus Paracoccidioides brasiliensis.
A calcineurina é uma fosfatase ativada por Ca2+ e calmodulina presente em todos os eucariotos que, em fungos, atua na sinalização de eventos em resposta a estímulos do ambiente e tem papel essencial na patogenicidade de fungos causadores de doenças. O Paracoccidioides brasiliensis é um fungo dimórfico causador da paracoccidioidomicose, uma micose sist

8. Avaliação macroscópica e microscópica do cimento Portland comum - CP I e do cimento Portland branco não estrutural - CPB incluídos na calvária de ratos / Macroscopic and microscopic evaluation of Portland Cement Joint - CP I and the Portland Cement White not structural - CPB included in the skull of rats
The biomaterials can be defined as substances of natural or synthetic origin that are tolerated on a temporary or permanent by the various tissues that make up the organs of living beings. Among these biomaterials can quote the mineral trioxide aggregate (MTA), which was developed at the University of Loma Linda, in the 90s. Since then, it stopped work on re

9. Interleukin-15: its role in microbial infections
Interleukin-15 (IL-15) is a pleiotropic cytokine which regulates the proliferation, survival and the secretory activities of many distinct cell types in the body. This cytokine is produced by macrophages and many other cell types in response to infectious agents; it controls growth and differentiation of T and B lymphocytes, activation of Natural Killer (NK)

10. High-throughput screening in enzyme assays for epoxide hydrolases and monooxygenases activity detection using whole cell / Triagem de alto desempenho para detecção de atividade de epoxido-hidrolases e monooxigenases utilizando celulas integras
Biocatalysis is a multidisciplinary area, where new technologies are developing rapidly in order to offer unique options and solutions to different organic chemistry problems, complementing the classical synthetic chemistry. Facing the need imposed by progress in this area, this project aims at the implementation of high-throughput screening (HTS) methodolog

12. Creating and Maintaining the Gastrointestinal Ecosystem: What We Know and Need To Know from Gnotobiology
Studying the cross talk between nonpathogenic organisms and their mammalian hosts represents an experimental challenge because these interactions are typically subtle and the microbial societies that associate with mammalian hosts are very complex and dynamic. A large, functionally stable, climax community of microbes is maintained in the murine and human ga
