“Crias do abuso na Amazônia”: os (ab)usos discursivos da imprensa paraense na cobertura de casos de violência sexual contra crianças e adolescentes

Esta Dissertação de Mestrado problematiza como os jornais paraenses, O Liberal e Diário do Pará, dois dos mais importantes periódicos da Amazônia na atualidade, produzem discursos sobre casos de violência sexual contra crianças e adolescentes. Tomamos, como suporte de pesquisa, notícias publicadas nas páginas policiais e em diversas editorias, ao longo da trajetória dos dois jornais, além de enunciados jornalísticos produzidos durante a vigência da Comissão Parlamentar de Inquérito (CPI) da Assembleia Legislativa do Estado do Pará (ALEPA), entre 2008 e 2010. Para tornar possível a análise discursiva sobre essa complexa temática, adotamos como metodologia a Análise do Discurso (AD) de vertente francesa, especialmente os postulados de Michel Foucault sobre discurso, história e poder, a fim de efetuarmos as leituras do corpus selecionado. Para aprofundarmos a nossa análise, fizemos um trabalho arqueológico da história da imprensa paraense para observarmos a atualização de redes de memória e as relações de poder que atravessam os discursos dos jornais sobre a temática, pois na microfísica de poder midiático amazônico ambos travam uma “guerra discursiva” registrada de forma peculiar em suas páginas. Assim, fizemos uma aproximação dos estudos da análise do discurso com os do jornalismo, por meio de teóricos do campo da Comunicação, como Nelson Traquina. Além disso, nossa pesquisa considerou nas análises as peculiaridades da Amazônia, região ao norte do país que sofre diversos apagamentos discursivos midiáticos nacionais ao longo da história e onde também observamos, em meio a sua diversidade, a prática cultural das “crias”, realidade que nossos estudos mostraram como secular e que até hoje retira crianças de cidades do interior para morar e estudar na capital. Essa e outras dinâmicas que envolvem o abuso e exploração sexual de crianças e adolescentes nos levaram à percepção de uma série de (ab)usos discursivos sobre o tema na imprensa paraense.

O saber fazer docente na educação para a sexualidade em Coimbra, Portugal: a realidade de 02 escolas de ensino básico

The research addresses the teacher know-how in relation to how it is crafted to education for sexuality in two public schools in Coimbra - Portugal, with teachers from different areas of the 3rd cycle of basic education (humanities, sciences and biological sciences), which corresponds to the Elementary School II in Brazil. It will be based on law 60/2009 of August 6, regulated by Decree 196-A of April 9, 2010 of the Ministry of Education - Portugal, which establishes the implementation of sexual education in primary and secondary schools across the country. This research is funded by FAPESP - Research Support Fund of the State of São Paulo, process number 2011/12902-3. The research was based on a qualitative approach, conducting case studies and using semistructured interviews for data collection. The performance of the topic of sexuality and gender relations at Portuguese’s classroom aims to provide young people the opportunity to exercise their sexuality in a responsible, healthy and pleasurable way. The law seeks to ensure that this work is established in the Portuguese school effectively. Therefore, the trajectory of teachers formation (initial or continuing) will also be a focus of this research, to understand how and where it is built and how they act in their daily classroom practices, with their students the sexuality and gender relations

Use of Cathorops spixii as bioindicator of pollution of trace metals in the Santos Bay, Brazil

In the present study Cathorops spixii, was evaluated as a bioindicator fish for trace metal pollution. Concentrations of cobalt (Co), iron (Fe), selenium (Se) and zinc (Zn) were determined by Instrumental Neutron Activation Analysis in liver. Mercury (Hg) and methyl-mercury (MeHg) were analyzed by Cold Vapor Atomic Absorption Spectrometry in muscles and livers. High concentrations of Co, Fe, Se and Zn were observed in C. spixii from Santos Bay in comparison to fish collected in a non-polluted site in the same Brazilian coast. These trace metal concentrations were out of the permissible levels for human consumption. Although, Hg and MeHg levels were low, the C. spixii could still be used as an effective bioindicator to observe trace metal behaviors in the environment in function of the bioaccumulation process observed mainly by other analyzed trace metals. Thus, the use of this species is strongly recommended to monitor the effects and behavior of trace metal pollution in aquatic ecosystems in Brazil due to its bioaccumulation function.

Field and laboratory studies to assess the effects of Vertimec (R) 18EC on Daphnia similis

The present study aimed to evaluate the interactions of the pesticide Vertimec (R) 18EC in aquatic ecosystems. In this respect, soil plots were contaminated with Vertimec (R) 18EC at the concentration indicated for strawberry crops (0.125 L of solution m(-2)). After the contamination, torrential rainfall was simulated and the surface runoff was collected and transferred to mesocosm tanks in five treatments, run in triplicate: (1) control-C; (2) runoff from an uncontaminated plot-UR; (3) runoff from the plot contaminated with Vertimec (R) 18EC-CR; (4) direct application of Vertimec (R) 18EC in the water-V and (5) water samples gathered randomly to verify whether there was contamination between the mesocosms-RS. Water samples from these tanks were also submitted to ecotoxicological tests with Daphnia similis and analyses to evaluate the limnological characteristics, in five collection periods over 10 days (240 h). Physical and chemical differences were observed in the water samples, mainly related to increased turbidity, suspended solids and nutrients (nitrogen and phosphate forms). Acute toxicity was observed for the direct application treatment for the entire experimental period, and in some periods for the CR treatment (from 48 h to 168 h). The results obtained suggest that the pesticide did not fully degrade during the study period (10 days) in the direct application treatment, demonstrating that the presence of other substances in the commercial formulation contribute to the maintenance of toxicity. This represents a potential risk for aquatic ecosystems in areas adjacent to where the chemical is applied. (C) 2011 Elsevier Inc. All rights reserved.

Oxidative Stress and Modification of Renal Vascular Permeability Are Associated with Acute Kidney Injury during P. berghei ANKA Infection

Malaria associated-acute kidney injury (AKI) is associated with 45% of mortality in adult patients hospitalized with severe form of the disease. However, the causes that lead to a framework of malaria-associated AKI are still poorly characterized. Some clinical studies speculate that oxidative stress products, a characteristic of Plasmodium infection, as well as proinflammatory response induced by the parasite are involved in its pathophysiology. Therefore, we aimed to investigate the development of malaria-associated AKI during infection by P. berghei ANKA, with special attention to the role played by the inflammatory response and the involvement of oxidative stress. For that, we took advantage of an experimental model of severe malaria that showed significant changes in the renal pathophysiology to investigate the role of malaria infection in the renal microvascular permeability and tissue injury. Therefore, BALB/c mice were infected with P. berghei ANKA. To assess renal function, creatinine, blood urea nitrogen, and ratio of proteinuria and creatininuria were evaluated. The products of oxidative stress, as well as cytokine profile were quantified in plasma and renal tissue. The change of renal microvascular permeability, tissue hypoxia and cellular apoptosis were also evaluated. Parasite infection resulted in renal dysfunction. Furthermore, we observed increased expression of adhesion molecule, proinflammatory cytokines and products of oxidative stress, associated with a decrease mRNA expression of HO-1 in kidney tissue of infected mice. The measurement of lipoprotein oxidizability also showed a significant increase in plasma of infected animals. Together, our findings support the idea that products of oxidative stress, as well as the immune response against the parasite are crucial to changes in kidney architecture and microvascular endothelial permeability of BALB/c mice infected with P. berghei ANKA.

Increased Antioxidant Content in Juice Enriched with Dried Extract of Pomegranate (Punica granatum) Peel

Antioxidants are compounds responsible for free radical scavenging in the body. They protect the organism from oxidative modification of cells and tissues. These modifications have been associated with degenerative diseases, atherosclerosis and carcinogenesis. Punica granatum displays high antioxidant potential due to the presence of phenolic compounds, which are capable of disease prevention. The present study showed the highest antioxidant activity in pomegranate peel than in seeds and pulp. Based on these results, pomegranate peel was used to produce dried extract that was added to commercial tomato juice and orange juice with strawberries. Analysis to determine the content of phenolic compounds and antioxidant activity was performed on pomegranate pulp, seeds and peel and in juices enriched with dried extract of pomegranate peel. The dried extract was responsible for a significant increase in antioxidant activity of the juices, proportional to the concentrations added. However, although both flavors of enriched juices displayed high antioxidant levels, the samples with higher dried extract concentrations received the lowest scores from sensory analysis participants due to the characteristic astringent flavor of pomegranate peels. Therefore, to obtain greater acceptance in the consumer market, we concluded that the maximum addition of dried pomegranate peel extract is 0.5% in tomato juice and orange juice with strawberries.

Bone marrow cells of swine: collection and separation

Bone marrow is a source of stem cells for greater and easier access, which is widely studied as a provider of hematopoietic and mesenchymal cells for various purposes, mainly therapeutic by the advances in research involving cell therapy. The swine is an animal species commonly used in the pursuit of development of experimental models. Thus, this study aimed to standardize protocol for collection and separation of bone marrow in swines, since this species is widely used as experimental models for various diseases. Twelve animals were used, which underwent bone marrow puncture with access from the iliac crest and cell separation by density gradient followed by a viability test with an average of 98% of viable cells. Given our results, we can ensure the swine as an excellent model for obtaining and isolation of mononuclear cells from bone marrow, stimulating several studies addressing the field of cell therapy.

Hyaluronidase splice variants are associated with histology and outcome in adenocarcinoma and squamous cell carcinoma of the lung

Heterogeneity of hyaluronidase (HYAL) expression has been identified in tumors and shows promise as an indicator of disease progression. The expression profile of alternatively spliced forms of HYAL was evaluated in tumors and normal lung tissue from 69 resected tumors of patients with adenocarcinomas and squamous cell carcinomas. HYAL1-wild-type (wt) and variants 1 to 5, HYAL2-wt, and HYAL3-wt, and variants 1 to 3 were identified by polymerase chain reaction and direct sequencing. Different proportions of the 3 HYAL-wt and variants were expressed in tumor and normal lung tissues. HYAL1-wt was associated with a poorer prognosis and HYAL3-vl with a better prognosis. HYAL splice variants are associated with histology and outcome, suggesting that strategies aimed at modulating their levels may be effective for lung cancer treatment. (C) 2012 Elsevier Inc.

Molecular epidemiology of the SH (small hydrophobic) gene of human respiratory syncytial virus (HRSV), over 2 consecutive years

Human respiratory syncytial virus (HRSV) strains were isolated from nasopharyngeal aspirates collected from 965 children between 2004 and 2005, yielding 424 positive samples. We sequenced the small hydrophobic protein (SH) gene of 117 strains and compared them with other viruses identified worldwide. Phylogenetic analysis showed a low genetic variability among the isolates but allowed us to classify the viruses into different genotypes for both groups, HRSVA and HRSVB. It is also shown that the novel BA-like genotype was well segregated from the others, indicating that the mutations are not limited to the G gene. (C) 2011 Elsevier B.V. All rights reserved.
