Objective: This study aimed evaluating histologically and histomorphometrically the response of the conjunctive tissue face to the implant of chlorhexidine chips in the subcutaneous tissues of rats. Study Design: In this research 35 male rats Wistar were used to analyze the biocompatibility and the degradation process of chlorhexidine chip. In each animal, it was made 2 incisions for subcutaneous implantation of chlorhexidine chip (test group) and a polytetrafluorethylene membrane (control group). The morphological changes in subcutaneous implantations were assessed after 1, 3, 5, 7, 10, 14, 21 days. The data were submitted to Friedman nonparametric test to analyze the comparisons among observation periods and to allow the comparison among groups. Results: Differences were found in the analysis of the inflammatory response when comparing the tested materials (p values <= 0.05). In test group was observed hemorrhage, edema and intense inflammatory infiltrate predominantly neutrophilic around material. From 3-day and subsequent periods was verified granulation tissue externally at this infiltrate. From 10-day on was observed crescent area of degradation of chlorhexidine chip, associated with neutrophilic and macrophagic infiltrate, that maintained until 21-day. In the control group, moderate inflammatory infiltrate was observed initially, predominantly polymorphonuclear, edema and granulation tissue 3-day period. The inflammatory infiltrate was gradually replaced for granulation tissue, culminating in a fibrous capsule. Giant multinucleate cells situated at contact interface with the coating was examined since 3-day and persisted until 21-day. Conclusion: The chlorhexidine chip induces an intense acute inflammatory response at subcutaneous tissue of rats. Therefore, at conditions of this study was not biocompatible.

There is a molecular crosstalk between the trophoblast and maternal immune cells of bovine endometrium. The uterine cells are able to secrete cytokine/chemokines to either induce a suppressive environment for establishment of the pregnancy or to recruit immune cells to the endometrium to fight infections. Despite morphological differences between women and cows, mechanisms for immune tolerance during pregnancy seem to be conserved. Mechanisms for uterine immunesuppression in the cow include: reduced expression of major histocompatability proteins by the trophoblast; recruitment of macrophages to the pregnant endometrium; and modulation of immune-related genes in response to the presence of the conceptus. Recently, an eGFP transgenic cloned embryo model developed by our group showed that there is modulation of foetal proteins expressed at the site of syncytium formation, suggesting that foetal cell can regulate not only by the secretion of specific factors such as interferon-tau, but also by regulating their own protein expression to avoid excessive maternal recognition by the local immune system. Furthermore, foetal DNA can be detected in the maternal circulation; this may reflect the occurrence of an invasion of trophoblast cells and/or their fragment beyond the uterine basement membrane in the cow. In fact, the newly description of exosome release by the trophoblast cell suggests that could be a new fashion of maternal-foetal communication at the placental barrier. Additionally, recent global transcriptome studies on bovine endometrium suggested that the immune system is aware, from an immunological point of view, of the presence of the foetus in the cow during early pregnancy.

Utilizando resultados de trabalho estatístico com base nos dados da Relação Anual de Informações Sociais (RAIS), que permitem caracterizar a indústria de calçados de Nova Serrana (MG) como um sistema local de produção, e nos resultados de pesquisa de campo efetuada em abril de 2002, quando foram realizadas entrevistas e visitas em empresas e instituições locais, o artigo estuda o sistema local de produção de Nova Serrana tanto em termos do sistema como um todo quanto das empresas e instituições que o compõem. O objetivo é produzir, nesses dois níveis de análise, evidências que possam orientar ações públicas e privadas, visando ao aprimoramento do sistema e das empresas locais em duas esferas: (1) produtiva e tecnológica, em seus vários desdobramentos, e (2) institucional e organizacional. Para isso, caracteriza e dimensiona primeiramente o sistema local em termos de sua localização e região de influência, sua logística, população e empregos gerados, história e evolução, estrutura de produção, instituições de apoio, contexto social, cultural e político. em seguida, caracteriza as empresas em termos de tamanho e quanto a: desenvolvimento de produto, sistemas de comercialização, relações cooperativas, interações com fornecedores, fontes de informação para desenvolvimento de produtos e sobre mercados e processos de fabricação, práticas e políticas quanto à qualidade, ao financiamento e a outros aspectos pertinentes ao caso em estudo. Por fim, ressalta os problemas mais relevantes que podem ser objeto de políticas públicas e/ou de ações conjuntas das empresas e instituições locais.

From a diagnostic on the learning of written text, this research aimed to carry out educational activities aimed at textual production, performing operation and activity of reflection on texts written by students in a learning situation of parallel recovery, aiming to improve the standard textuality of his written production. These actions were guided from the conception of language as social practice and discourse and, later, a survey was made in the standard of textuality textual productions resulting from such actions. 5 students participated in the research of a 4th grade of elementary school, a School of Duartina peripheral zone integrating the local school system of that city. The textual productions written by these students were analyzed from three categories: common mistakes in the process of literacy, with subdivisions: phonetic transcription, dialetação, hollow hipossegmentação or vocabulary, or improper separation hiperssegmentação, overcorrection, exchange, omission or addition letters, phonemes homorganic exchange; factors textual and contextual, in which it reviewed the following factors: coherence, cohesion and story elements, clarity, in which category were analyzed: the segmentation of text into paragraphs, grammar errors of different nature, use of direct and indirect speech. The results of the intervention and ongoing analysis of data shows that there has been considered developments in the performance of the written production of the research subjects
