Aiming to describe the patterns of the fish assemblages organization in streams of the Iguatemi River basin we sampled streams with seine nets and sieves from November/1999 to August/2000. We collected 567 individuals distributed in 24 species. We detected statistically significant influence of the streams characteristics upon species diversity. The species composition was hardly explained by the physical and chemical characteristics of the streams. Then we detected significant influence of the fish ecomorphology in the species occurrence (Mantel r = -0.34; P = 0.04), but not in the distribution of its abundance (Mantel r = -0.21; P = 0.07). We verified through the species co-occurrence index (C-score) that its composition in the studied streams is stochastic.

The objective of this work was to make a comparative analysis of germ cell organization at different stages of cellular differentiation in adult males of Dendropsophus nanus (Boulenger, 1889), Pseudis limellum (Cope, 1862), P. paradoxa (Linnaeus, 1758), and Scinax acuminatus (Cope, 1862), belonging to the family Hylidae; and Leptodactylus chaquensis (Cei, 1950) and L. podicipinus (Cope, 1862), belonging to the family Leptodactylidae, collected in the Pantanal and in Serra da Bodoquena, Mato Grosso do Sul State, Brazil. The testes were removed and fixed, dehydrated in a graded series of ethanol and embedded in methacrylate glycol resin (Historesin Leica®). The sections were stained by 1% toluidine blue and observed under light microscope. It was detected that all individual of the Hylidae family show, throughout the year, the presence of all germ cell types of spermatogenesis. However, all Leptodactylidae family individuals only show the presence of all germ cell types during the rainy season. The variations of characteristics in seminiferous epithelium organization, as well as the evident difference in the amount of spermatozoa inside the tubules, are evidence that the anurans in this work show different forms of spermatogenesis development throughout the year: the cycle is continuous for the Hylidae family, and discontinuous with explosive release of spermatozoa for the Leptodactylidae family.

Objective: The aim of our study was to assess the likelihood of IUI success as a function of the previously described predictive factors, including sperm morphology according to the new reference values defined by WHO. Material and Methods: This retrospective study enrolled 300 couples which underwent IUI. Regression analyses were used to correlate maternal age, number of preovulatory follicles on the day of hCG administration, number of inseminated motile sperm, and normal sperm morphology with clinical pregnancy. Results are expressed as odds ratio (OR) with 95% of confidence intervals (CI). Results: Women older than 35 years showed a lower pregnancy rate (6.5% vs 18.2%, p=0.017). Logistic regression models confirmed the lower chance of pregnancy occurrence for older women (OR: 0.39; CI: 0.16-0.96; p=0.040). The presence of two or more preovulatory follicles on the day of hCG administration resulted in higher pregnancy rate when compared to cases in which only one preovulatory follicle was present (18.6% vs 8.2%, p=0.011). The regression model showed a more than two fold increase on probability of pregnancy when two or more preovulatory follicles were detected (OR: 2.58; CI: 1.22-5.46, p=0.013). The number of inseminated motile sperm positively influenced pregnancy occurrence (OR: 1.47; CI: 0.88-3.14, p=0.027). Similar pregnancy rates were observed when semen samples were classified as having normal or abnormal morphology (10.6% vs 10.2%, p=0.936). Conclusion: Our results demonstrate that sperm morphological normalcy, according to the new reference value, has no predictive value on IUI outcomes. © Todos os direitos reservados a SBRA - Sociedade Brasileira de Reprodução Assistida.

The patellofemoral pain syndrome (PFPS) is defined as a retropatellar or anterior knee pain, without another disease. It affects until 25% of the population, being more common in women and trained persons. As others pathologies, PFPS have been affected the training of elite and amateurs athletes. Thereby, the general purpose of this study was discuss the occurrence of PFPS as a sports injury, there prevention possibilities and the appropriate recovery training after injury. It had been developed a literature review addressing the specific characteristics of the syndrome, its diagnosis, its target population, its development, how it affects the training and which are their possibilities of prevention and treatment. © FTCD/FIP-MOC.

The search for a dialogical interpretation on the concept theory is the purpose of this paper. It uses the concept of dialogism, proposed by Bakhtin, which refers to the interaction occurring among the social actors in the process of (re)construction of language. Starting from the analysis of texts on concept theory authored by Dahlberg, Hjorland, Tennis and Tennis and Sutton, the convergent, divergent and complementary aspects related to the concepts advocated by the authors are discussed. The analysis revealed that, although these concepts have been built individually, they are reflections of distinct currents of thought and of the historical moments that have influenced each author's ideas. It can be argued, therefore, that the studied concepts were developed on dialogue with other authors and among themselves.

Considering knowledge organization and representation as a theoretical line used by Information Science to face the subject approach to information, in a dialogical relation with subject cataloguing, indexing and analyse documentaire, this article carries out a domain-analysis of Scire journal (1995-2010) in order to identify the scientific production in the mentionned theoretical lines as well as their relationships. Scire constitutes an environment where members of the different paradigms have found an space to relate each other.
