Antisperm antibodies in infertile men and their correlation with seminal parameters

Aim: Antisperm antibodies (ASA) in males cause the autoimmune disease 'immune infertility'. The present study intended to detect the presence of ASA and their incidence in men with unexplained infertility, as well as to evaluate the correlation between the presence of ASA and semen parameter alterations. Methods: Blood and sperm assessment were collected to carry out a direct and indirect mixed antiglobulin reaction (MAR) test and semen analysis in infertile and fertile men from the University Hospital of the Faculty of Medicine, Sao Paulo State University, Sao Paulo. Results: In the MARtest, 18.18% of infertile men were positive for ASA. In fertile men, no positivity was found. A significant correlation between the presence of ASA with an increased white blood cell count plus a decreased hypoosmotic swelling test result was observed. Conclusions: The results indicate that ASA are involved in reduced fertility. It is not ASA detection per.se that provides conclusive information about the occurrence of damage to fertility. The correlation between infertility and altered seminal parameters reinforce the ASA participation in this pathology. © 2007 The Authors Journal compilation. © 2007 Japan Society for Reproductive Medicine.

Phylogeny and taxonomic revision of the spider mite genera Aponychus, Paraponychus and Stylophoronychus using morphology (Acari:Tetranychidae)

Despite their great importance as pests of cultivated plants worldwide, members of the family Tetranychidae have never been subjected to a thorough cladistic analysis to reveal the history and relationships among related genera. Herein, we provide the first phylogenetic analysis and taxonomic review of species of the genera Aponychus, Paraponychus and Stylophoronychus using morphological characters. The results indicate a monophyletic clade uniting the aforementioned genera, although none of the three genera were recovered as monophyletic. We reinstate the tribe Aponychini as the taxon containing those three genera. Aponychus bambusae and A. aequilibris are herein considered junior synonyms of Stylophoronychus vannus and A. corpuzae, respectively. © 2013 CSIRO.

The dynamic implementation of non-overt arguments in nominalizations

Valency is an inherent property of nominalizations representing higher-order entities, and as such it should be included in their underlying representation. On the basis of this assumption, I postulate that cases of non-overt arguments, which are very common in Brazilian Portuguese and in many other languages of the world, should be considered a special type of valency realization. This paper aims to give empirical support to this postulate by showing that non-overt arguments are both semantically and pragmatically motivated. The semantic and pragmatic motivations for non-overt arguments may be accounted for by the dynamic implementation of the FDG model. I argue that the way valency is realized by means of non-overt arguments suggests a strong parallelism between nominalizations and other types of non-finite embedded constructions – like infinitival and participial ones. By providing empirical evidence for this parallelism I arrive at the conclusion that there are at least three kinds of non-finite embedded constructions, rather than only two, as suggested by Dik (1997).

Botticelli: pintura e teoria

Esta obra analisa com profundidade o trabalho do florentino Sandro Botticelli (aproximadamente 1445-1510), um dos mais conhecidos representantes da arte renascentista, autor de afrescos que decoram a Capela Sistina e de ícones da pintura ocidental, como O Nascimento de Vênus e A Primavera. Aqui, Débora Barbam Mendonça toma como ponto de partida a comparação do estudo Clássico e Anticlássico, de Giulio Carlo Argan, sobre a pintura do florentino, com obras de outros teóricos e historiadores. O objetivo é estudar o conceito de graça na pintura de Boticelli e confrontá-lo com os pressupostos teóricos da produção do artista. A autora discute a interpretação de especialistas sobre o Renascimento como período histórico, filosófico e artístico, discorre sobre o legado teórico da pintura humanista e busca o ideal de belo intrínseco à obra de Boticelli. No terceiro capítulo, Mendonça analisa detalhadamente a pintura A Virgem do magnificat como referência para situar Boticelli como artista intelectual do Renascimento e destacar na obra sua ideia de graça. A filósofa conclui que Boticelli seguia uma linha teórica, mas a partir de uma escolha individual, ou seja, desenvolvia uma estética psicológica. E, por meio dos elementos formais de que dispunha, transmitia em suas obras o conceito de graça, transpondo ao mesmo tempo o resultado do diálogo que mantinha com a Filosofia, a ciência, a religião e, nostalgicamente, com a Antiguidade

Confirmatory factor analysis of different versions of the Body Shape Questionnaire applied to Brazilian university students

This study aimed at evaluating the validity, reliability, and factorial invariance of the complete (34-item) and shortened (8-item and 16-item) versions of the Body Shape Questionnaire (BSQ) when applied to Brazilian university students. A total of 739 female students with a mean age of 20.44 (standard deviation = 2.45) years participated. Confirmatory factor analysis was conducted to verify the degree to which the one-factor structure satisfies the proposal for the BSQ's expected structure. Two items of the 34-item version were excluded because they had factor weights (lambda)< 40. All models had adequate convergent validity (average variance extracted =.43-.58; composite reliability=.85-.97) and internal consistency (alpha =.85-.97). The 8-item B version was considered the best shortened BSQ version (Akaike information criterion = 84.07, Bayes information criterion = 157.75, Browne-Cudeck criterion= 84.46), with strong invariance for independent samples (Delta chi(2)lambda(7)= 5.06, Delta chi(2)Cov(8)= 5.11, Delta chi(2)Res(16) = 19.30).
