O TRABALHAR E O ESTUDAR NO CONTEXTO UNIVERSITÁRIO: UMA ABORDAGEM COM TRABALHADORES-ESTUDANTES

O estudo teve como objetivo compreender a relação entre o trabalhar e o estudar, de estudantes de Enfermagem que exercem concomitante a atividade de Técnicos em Enfermagem, inseridos no curso de graduação em Enfermagem em uma universidade pública do Mato Grosso. Trata-se de uma pesquisa de campo com abordagem qualitativa, cuja coleta de dados foi realizada por meio de entrevistas semiestruturadas com cinco trabalhadores-estudantes, as quais foram analisadas por meio da Análise de Conteúdo. Como resultados emergiram as seguintes categorias: “Universidade x Atividade Laboral”, no qual foram abordadas, principalmente, as dificuldades oriundas ao trabalho e ao estudo e “Conciliando as atividades acadêmicas e as atividades laborais” evidenciando as estratégias elaboradas pelos acadêmicos a fim de finalizar o percurso acadêmico com êxito. O estudo indicou a necessidade de que, a política de permanência para os estudantes da educação superior pública estenda seus benefícios ao trabalhador-estudante, visto que é cada vez mais frequente a sua presença nesse nível de ensino.

An Adjoint-Based Approach for a Class of Nonlinear Fokker-Planck Equations and Related Systems

Here, we introduce a numerical approach for a class of Fokker-Planck (FP) equations. These equations are the adjoint of the linearization of HamiltonJacobi (HJ) equations. Using this structure, we show how to transfer properties of schemes for HJ equations to FP equations. Hence, we get numerical schemes with desirable features such as positivity and mass-preservation. We illustrate this approach in examples that include mean-field games and a crowd motion mode

Identification of COL6A1 as a differentially expressed gene in human astrocytomas

Diffuse infiltrating gliomas are the most common tumors of the central nervous system. Gliomas are classified by the WHO according to their histopathological and clinical characteristics into four classes: grade I (pilocytic astrocytoma), grade II (diffuse astrocytoma), grade III (anaplastic astrocytoma), and grade IV (glioblastoma multiforme). Several genes have already been correlated with astrocytomas, but many others are yet to be uncovered. By analyzing the public SAGE data from 21 patients, comprising low malignant grade astrocytomas and glioblastomas, we found COL6A1 to be differentially expressed, confirming this finding by real time RT-PCR in 66 surgical samples. To the best of our knowledge, COL6A1 has never been described in gliomas. The expression of this gene has significantly different means when normal glia is compared with low-grade astrocytomas (grades I and II) and high-grade astrocytomas (grades III and IV), with a tendency to be greater in higher grade samples, thus rendering it a powerful tumor marker

Cytotoxin-associated gene a strains of Helicobaciter pylori represent a risk factor for the development of microalbuminuria in type 2 diabetes

The reasons why diabetic patients with microalbuminuria have marked endothelial damage (1,2) and an increased risk of atherosclerosis (3,4) are unclear. Infection with Helicobacter pylori, especially with strains carrying the cytotoxin-associated gene A (CagA), might represent a causal factor, since anti-CagA antibodies elicited by infection may cross-react with endothelial antigens (5), increasing the vascular damage associated with diabetes itself and consequent albumin leakage. Furthermore, infection might induce a persistent systemic inflammatory response, which is a recognized risk factor for atherosclerosis (6). In this study, we investigated the possible pathogenetic role of CagA-positive H. pylori strains in type 2 diabetic patients with microalbuminuria
