Mídia e gênero: análise crítica da violência contra a mulher no telejornalismo

This thesis is consisted of a theoretical and empirical study about the treatment given by media, particularly on telejournalism, to violence against women. It aims to analyze and reflect about the role of media, particularly television, on the process of reproduction of patriarchy system of gender on the context of Brazilian society, from content and narrative news about crimes committed against Andreia Rodrigues and Eliza Samudio. In light of the critical perspective, we seek to apprehend the particularities of patriarchy as a system of domination and subjugation of women, and also reveal the involvement of traditional means of media on reproduction and maintenance of inequality between men and women. To apprehend that reality, we had as guidance a critical social theory, grounded in historical-dialectical materialism which enabled us to apprehend the phenomenon under investigation actually enrolled in a dynamic and contradictory reality. The research had qualitative approach. We appeal to the specialized literature of the area from classical and contemporary authors. We conducted a content analysis of categorized matters, and interviews with individuals involved in issues of gender and / or communication. The critical examination of the matters indicated that television journalism is permeated by the contradictions inherent in social life, means that states and restates the ideology of ruling classes, their values and worldviews, but also express conflicts and social demands. The study revealed that prevails on television playing stereotypes and gender inequalities. We could also see that violence against women gets a sensationalist overblown approach and with no insights on the social relations that determine and base it.

A Novel Diagnostic Target in the Hepatitis C Virus Genome

BackgroundDetection and quantification of hepatitis C virus (HCV) RNA is integral to diagnostic and therapeutic regimens. All molecular assays target the viral 5'-noncoding region (59-NCR), and all show genotype-dependent variation of sensitivities and viral load results. Non-western HCV genotypes have been under-represented in evaluation studies. An alternative diagnostic target region within the HCV genome could facilitate a new generation of assays.Methods and FindingsIn this study we determined by de novo sequencing that the 3'-X-tail element, characterized significantly later than the rest of the genome, is highly conserved across genotypes. To prove its clinical utility as a molecular diagnostic target, a prototype qualitative and quantitative test was developed and evaluated multicentrically on a large and complete panel of 725 clinical plasma samples, covering HCV genotypes 1-6, from four continents (Germany, UK, Brazil, South Africa, Singapore). To our knowledge, this is the most diversified and comprehensive panel of clinical and genotype specimens used in HCV nucleic acid testing (NAT) validation to date. The lower limit of detection (LOD) was 18.4 IU/ml (95% confidence interval, 15.3-24.1 IU/ml), suggesting applicability in donor blood screening. The upper LOD exceeded 10(-9) IU/ml, facilitating viral load monitoring within a wide dynamic range. In 598 genotyped samples, quantified by Bayer VERSANT 3.0 branched DNA (bDNA), X-tail-based viral loads were highly concordant with bDNA for all genotypes. Correlation coefficients between bDNA and X-tail NAT, for genotypes 1-6, were: 0.92, 0.85, 0.95, 0.91, 0.95, and 0.96, respectively; X-tail-based viral loads deviated by more than 0.5 log10 from 5'-NCR-based viral loads in only 12% of samples (maximum deviation, 0.85 log10). The successful introduction of X-tail NAT in a Brazilian laboratory confirmed the practical stability and robustness of the X-tail-based protocol. The assay was implemented at low reaction costs (US$8.70 per sample), short turnover times (2.5 h for up to 96 samples), and without technical difficulties.ConclusionThis study indicates a way to fundamentally improve HCV viral load monitoring and infection screening. Our prototype assay can serve as a template for a new generation of viral load assays. Additionally, to our knowledge this study provides the first open protocol to permit industry-grade HCV detection and quantification in resource-limited settings.

HISTORICAL PERSPECTIVE and HUMAN CONSEQUENCES of AFRICANIZED BEE STINGS IN THE AMERICAS

In 1956, Africanized bees began to spread in the American continent from southern Brazil, where original African bees mated with European bees. A few years later, in 1990, these Africanized bees reached the United States and were found in Texas. Currently, these hybrid bees are found in several North American states and will probably reach the Canadian border in the future. Although the presence of Africanized bees had produced positive effects on Brazilian economy, including improvement in crop pollination and in honey production, turning Brazil into a major exporter, the negative impacts-such as swarming, aggressive behavior, and the ability to mass attack-resulted in serious and fatal envenomation with humans and animals. Victims of bee attacks usually develop a severe envenomation syndrome characterized by the release of a large amount of cytokines [interleukins (IL) IL-1, IL-6, IL-8], and tumor necrosis factor (TNF). Subsequently, such cytokines produce an acute inflammatory response that triggers adverse effects on skeletal muscles; bone marrow; hepatic and renal functions; and cardiovascular, central nervous, and immune systems. Finally, the aim of the present review is to study historical characteristics and current status of Africanized bees' spread, the composition of their venom, the impact of the bees on the Brazilian economy and ecology, and clinical aspects of their stings including immune response, and to suggest a protocol for bee sting management since there is no safe and effective antivenom available.

Crotoxin: Novel activities for a classic beta-neurotoxin

Crotoxin, the main toxin of South American rattlesnake (Crotalus durissus terrificus) venom, was the first snake venom protein to be purified and crystallized. Crotoxin is a heterodimeric beta-neurotoxin that consists of a weakly toxic basic phospholipase A(2) and a nonenzymatic, non-toxic acidic component (crotapotin). The classic biological activities normally attributed to crotoxin include neurotoxicity, myotoxicity, nephrotoxicity and cardiotoxicity. However, numerous studies in recent years have shown that crotoxin also has immunomodulatory, anti-inflammatory, anti-microbial, anti-tumor and analgesic actions. In this review, we describe the historical background to the discovery of crotoxin and its main toxic activities and then discuss recent structure-function studies and investigations that have led to the identification of novel pharmacological activities for the toxin.

Hydrochemical evaluation of the quality of some Brazilian waters

This investigation was carried out within the Parane sedimentary basin and neighbourhood in Brazil and involved the sampling of different water types with the purpose of evaluating its quality. Several methods were utilized for acquiring the hydrochemical data and a novel technique has been developed for evaluating the gross alpha and beta radioactivities in water, through a combined gamma-alpha spectrometry technique. The results obtained for the analyzed samples were compared with the guideline values established by the São Paulo State and Brazilian Health Ministry legislations for defining potable water standards and for the prevention and control of pollution in the environment. The hydrochemical data allowed evaluation of diverse problems related to the interaction between society and the environment such as sugarcane production and the releases associated with gas stations suppliers. The geogenic input of sulfate in groundwater was also identified. The established radiometric technique was properly calibrated and successfully applied to the analysis of different water types utilized for human consumption.

Refiguração do tempo histórico pela ficção

M. Bakhtin afirma que a representação de acontecimentos, relações e processos no romance deve abranger a totalidade de uma época nela deve haver uma peculiar concatenação, literariamente expressa, espácio-temporal. Essa formulação contém elementos basilares para o entendimento e análise do romance, objeto deste estudo, Leite derramado de 2009 de Chico Buarque. A narrativa figura, pelo menos, duas grandes épocas históricas do Brasil: uma que vai do início do século XIX até 1930 e outra que vai desse momento ao início do XXI. É a representação da saga histórica da decadência de uma categoria social (fração da classe dominante), personificada na família Assumpção, com seus valores éticos e culturais, suas concepções de mundo e seu comportamento, estilizando sua dissolução social e moral. Ao fazer isso o romance coloca inúmeros problemas desde humano-existenciais até histórico-políticos para a reflexão do leitor.

Romance e realidade na ficção brasileira contemporânea

Este trabalho é uma reflexão sobre a representação do real no romance Inferno provisório, de Luiz Ruffato, considerando as proposições de Claudio Magris acerca da forma romanesca moderna e sua possível transformação nas últimas décadas. O objetivo é questionar de que modo o projeto estético do romance incorpora uma visão em profundidade do real, originando um princípio ético de análise e crítica da sociedade contemporânea.
