Mortalidade por causas externas no Município de São José do Rio Preto, no período de 1996-1998

Introduction: An epidemiological study of the mortality rates by injuries in São José do Rio Preto, State of São Paulo, Brazil, has been carried out. The period considered is 1996-1998. Objectives: To show injuries mortality rates in São José do Rio Preto-SP in 1996-98. Methods: The study was based on official data from the Mortality Information Service of the Brazilian Ministry of Health, and in a survey based on data from medical forensic examiners (IML). Software Epinfo6.0 and Tabwin was utilized for data analises. Results: The results were compared to values obtained in the literature for the other cities of São Paulo and Brazil. In the case of São José do Rio Preto, was observed a decrease in the number of deaths associated with external causes in the period, but particularly in deaths due to traffic accidents with motor vehicles an increase in cases of pedestrians killed by hit-and-run drivers, that is much larger than the corresponding values for Brazil and for the State of São Paulo. The study showed increase in rates of homicides, mainly in the 15 to 39 years age group. Conclusion: This result suggests that is important to start programs to reduce the number of deaths by injuries, as well as the necessity of monitoring locally all these data.

Dominance hierarchy in different stages of development in colonies of the primitively eusocial wasp Mischocyttarus cassununga (Hymenoptera, Vespidae)

Seven colonies of Mischocyttarus cassununga were studied under field conditions at Universidade Federal de Juiz de Fora, MG, in southeastern Brazil: in pre-emergence, post-emergence and decline stages, during 145.8 hours. Dominance interactions among the females were quantified to verify the dynamics of succession in the social hierarchy of the colonies. Early pre-emergence colonies present more intense aggressive interactions than late pre-emergence ones, because the females are engaged in securing the role of main egg layer in the nest. In post-emergence (pre-male) colonies the dominance hierarchy is more defined and the frequency of dominance and subordination behaviors were lower than in pre-emergence stages: most of the agonistic behaviors are restricted to the first ranked females (potentially queens) and the subordinate individuals play the role of workers in the nests. In the post-emergence, post-male, and decline stages the hierarchy is still maintained by the aggressive behaviors of the 1st-ranked female but because the presence of males and future nest foundresses these interactions are not well defined in a linear way.

A organização da informação hipertextual no artigo jornalístico: em busca das marcas ideológicas

Discusses some aspects of newspaper hypertextual article in order to find their ideological marks. Assumes that the choice of the element of contact with other texts (links), when producing an article reveals the author's ideology and the institution he represents. Intends to offer the less experienced reader of news, conditions to the development of more fruitful reading. Argues that reading is a process of interaction between reader and text and that requires the presence of an active reader, able to construct new meanings. Establishes as a general objective to identify the ideological marks presents in hypertext and its relation to the critical reading of the media. This theme is treated with special attention to its educational aspects, aiming at understanding the reality that educators must become familiar with, in order to turn more effective the processes of education for the media.

The intricate role of mast cell proteases and the annexin A1-FPR1 system in abdominal wall endometriosis

Endometriosis is a continuous and progressive disease with a poorly understood aetiology, pathophysiology and natural history. This study evaluated the histological differences between eutopic and ectopic endometria (abdominal wall endometriosis) and the expression of mast cell proteases (tryptase and chymase), annexin A1 (ANXA1) and formyl peptide receptor 1 (FPR1). Ectopic endometrium from 18 women with abdominal wall endometriosis and eutopic endometrium from 10 women without endometriosis were obtained. The endometrial samples were analysed by histopathology, immunohistochemistry and ultrastructural immunogold labeling to determine mast cell heterogeneity (tryptase and chymase positive cells) and the expression levels of ANXA1 and FPR1. Histopathological analysis of the endometriotic lesions showed a glandular pattern of mixed differentiation and an undifferentiated morphology with a significant influx of inflammatory cells and a change in mast cell heterogeneity, as evidenced by a significant increase in the number of chymase-positive cells and endogenous chymase expression. The undifferentiated glandular pattern of endometriotic lesions was positively associated with a marked increase and co-localization of ANXA1 and FPR1 in the epithelial cells. In conclusion, the co-upregulated expression of mast cell chymase and ANXA1–FPR1 system in ectopic endometrium suggests their involvement in the development of endometriotic lesions.

O papel das emissoras educativas no Brasil em tempo de eleições

The concept of educational radio is present in the Brazilian Code of Broadcasting in 1963, valued by an Interministerial 1999.According to the Ministry of Communications, only 176 stations are considered educational universe of 3,000 existing radios in Brazil. In this context, the study proposes to establish a discussion on the educational experiences obtained from the radio, considering the Brazilian radio culture that favors concessions to trade groups and religious politicians. The challenge will be to move toward a program that combines educational content, entertainment, and thus ensures a common universe of communication skills enabling the adult radio listeners their actual interaction with the world around him. The methodology will work in the literature from texts on the subject, and the result of practical observations collected during visits to the broadcasters, programming and analysis.

Cytotoxicity tests for nanostructured chitosan/PEO membranes using the agar diffusion method

Electrospinning is used to produce fibers in the nanometer range by stretching a polymeric jet using electric fields of high magnitude. Chitosan is an abundant natural polymer that can be used to obtain biocompatible nanostructured membranes. The objectives of this work were to obtain nanostructured membranes based on blends of chitosan and polyoxyethylene (PEO), and evaluate their thermal and morphological properties, as well as their in vitro biocompatibility by agar diffusion cytotoxicity tests for three different cell lines. A nanostructured fibrous membrane with fiber diameters in the order of 200 nm was obtained, which presented a rough surface and thickness ranging from one to two millimeters. The results of the cytotoxicity tests evidenced that the chitosan/PEO membranes are non-toxic to the cells studied in this work. Further, the electrospinning technique was effective in obtaining nanostructured chitosan/PEO membranes, which showed biocompatibility according to in vitro preliminary tests using the cell lines.

Cyan fluorescent protein expression in ganglion and amacrine cells in a thy1-CFP transgenic mouse retina.

PURPOSE: To characterize cyan fluorescent protein (CFP) expression in the retina of the thy1-CFP (B6.Cg-Tg(Thy1-CFP)23Jrs/J) transgenic mouse line. METHODS: CFP expression was characterized using morphometric methods and immunohistochemistry with antibodies to neurofilament light (NF-L), neuronal nuclei (NeuN), POU-domain protein (Brn3a) and calretinin, which immunolabel ganglion cells, and syntaxin 1 (HPC-1), glutamate decarboxylase 67 (GAD(67)), GABA plasma membrane transporter-1 (GAT-1), and choline acetyltransferase (ChAT), which immunolabel amacrine cells. RESULTS: CFP was extensively expressed in the inner retina, primarily in the inner plexiform layer (IPL), ganglion cell layer (GCL), nerve fiber layer, and optic nerve. CFP fluorescent cell bodies were in all retinal regions and their processes ramified in all laminae of the IPL. Some small, weakly CFP fluorescent somata were in the inner nuclear layer (INL). CFP-containing somata in the GCL ranged from 6 to 20 microm in diameter, and they had a density of 2636+/-347 cells/mm2 at 1.5 mm from the optic nerve head. Immunohistochemical studies demonstrated colocalization of CFP with the ganglion cell markers NF-L, NeuN, Brn3a, and calretinin. Immunohistochemistry with antibodies to HPC-1, GAD(67), GAT-1, and ChAT indicated that the small, weakly fluorescent CFP cells in the INL and GCL were cholinergic amacrine cells. CONCLUSIONS: The total number and density of CFP-fluorescent cells in the GCL were within the range of previous estimates of the total number of ganglion cells in the C57BL/6J line. Together these findings suggest that most ganglion cells in the thy1-CFP mouse line 23 express CFP. In conclusion, the thy1-CFP mouse line is highly useful for studies requiring the identification of ganglion cells.
