O ESTÁGIO CURRICULAR SUPERVISIONADO NA FORMAÇÃO INICIAL DE PROFESSORES: O QUE DIZEM PESQUISAS SOBRE A TEMÁTICA?

Este estudo faz parte de uma pesquisa de mestrado em desenvolvimento, que objetivou mapear dissertações da Base de Dados de Teses e Dissertações (BDTD) voltadas para a temática do Estágio na Formação Inicial. Versa sobre o Estado do Conhecimento (MOROSONI; FERNANDES, 2014), levando em consideração que este, a princípio, é uma busca em que a revisão da literatura se faz presente. O estudo de cunho qualitativo busca resposta para a questão: O que as dissertações evidenciam sobre o Estágio Curricular Supervisionado na formação inicial de professores? Os descritores de busca foram: formação de professores, estágio supervisionado e formação inicial, com recorte temporal de 2010 a 2020. Os resultados encontrados convergem para a importância do estágio na construção de saberes e da identidade profissional, mas o currículo precisa acompanhar as necessidades formativas, dando abertura para atividades extraclasses e acompanhamento efetivo que suscite de forma concreta a parceria entre as instituições envolvidas

The Schistosoma mansoni cyclophilin A epitope 107-121 induces a protective immune response against schistosomiasis

Great efforts have been made to identify promising antigens and vaccine formulations against schistosomiasis. Among the previously described Schistosoma vaccine candidates, cyclophilins comprise an interesting antigen that could be used for vaccine formulations. Cyclophilin A is the target for the cyclosporine A, a drug with schistosomicide activity, and its orthologue from Schistosoma japonicum induces a protective immune response in mice. Although Schistosoma mansoni cyclophilin A also represents a promising target for anti-schistosome vaccines, its potential to induce protection has not been evaluated. In this study, we characterized the cyclophilin A (SmCyp), initially described as Smp17.7, analyzed its allergenic potential using in vitro functional assays, and evaluated its ability to induce protection in mice when administered as an antigen using different vaccine formulations and strategies. Results indicated that SmCyp could be successfully expressed by mammalian cells and bacteria. The recombinant protein did not promote IgE-reporter system activation in vitro, demonstrating its probable safety for use in vaccine formulations. T and B-cell epitopes were predicted in the SmCyp sequence, with two of them located within the active isomerase site. The most immunogenic antigen, SmCyp (107–121), was then used for immunization protocols. Immunization with the SmCyp gene or protein failed to reduce parasite burden but induced an immune response that modulated the granuloma area. In contrast, immunization with the synthetic peptide SmCyp (107–121) significantly reduced worm burden (48–50%) in comparison to control group, but did not regulate liver pathology. Moreover, the protection observed in mice immunized with the synthetic peptide was associated with the significant production of antibodies against the SmCyp (107–121) epitope. Therefore, in this study, we identified an epitope within the SmCyp sequence that induces a protective immune response against the parasite, thus representing a promising antigen that could be used for vaccine formulation against schistosomiasis

As manifestações clínicas do portador de paralisia facial

Introdução: A paralisia facial e um sintoma de um transtorno de base resultante em imobilidade e incapacidade de executar a mímica facial e a expressão emotiva. São várias as etiologias deste acometimento, sendo a classificação em paralisia facial periférica, representada classicamente pela paralisia de Bell e a central, pelo acidente vascular encefálico, adotada para auxiliar na investigação e seguimento clínico adequado. Objetivo: Descrever sobre a paralisia facial, com foco em características clínicas que propiciem ao diagnóstico precoce, medidas terapêuticas e restauração imediata. Metodologia: Revisão narrativa que selecionou artigos disponibilizados na íntegra publicados no recorte temporal de 2008 até 2022. Resultados: Dos 10 artigos incluídos neste estudo, todos realizaram uma ampla análise sobre a temática, a qual propiciou a disseminação de informações atualizadas sobre conceito, diagnóstico diferencial entre duas condições clínicas opostas resultantes em paralisia facial, manifestações, avaliação clínica e manejo adequado. Conclusão: Estudos ainda urgem em ser feitos no intuito de orientar melhor os profissionais e a comunidade a respeito da paralisia facial e a importância que possui o acompanhamento e seguimento precoce.

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
