La représentation des sexes dans les manuels defrançais langue étrangère pour le collège suédois

Dans notre travail nous avons décidé  d’analyser et de discuter le «gender» et l’égalité des sexes  comme ce sont des  thèmes actuels en Suède avec le débat sur la répartition inégale des sexes dans des différents domaines, par exemple sur le marché de l’emploi, au sujet des salaires et dans l’enseignement et parce que ce sont des questions qui nous intéressent personnellement beaucoup comme mère, femme  et future  professeur.  Le champ de notre travail s’est restreint à l’analyse des manuels du français comme langue étrangère pour le collège suédois.

Publicações indexadas geradas a partir de resumos de congressos de angiologia e cirurgia vascular no Brasil

CONTEXTO: Grande parte da produção científica apresentada em congressos não é publicada. Mesmo nos países do primeiro mundo, os números demonstram que essa perda é expressiva. OBJETIVO: Dimensionar o número de artigos publicados e indexados em bases de dados nacionais e internacionais, a partir dos títulos e autores de temas livres ou painéis dos congressos brasileiros de cirurgia vascular de 2001 e 2003. MÉTODOS: Foram pesquisados os 541 e 567 resumos apresentados, respectivamente, no XXXIV Congresso Brasileiro de Angiologia e Cirurgia Vascular, em 2001 e no XXXV Congresso de Angiologia e Cirurgia Vascular, em 2003. Foi realizada pesquisa computadorizada através dos seguintes instrumentos de busca: Scirus, Bireme, LILACS, SciELO, MEDLINE-PubMed e Biblioteca Cochrane, Google Acadêmico e índices remissivos e onomásticos do Jornal Vascular Brasileiro. Os artigos foram classificados em internacionais ou nacionais e em completos ou modificados. RESULTADOS: Foram encontrados 21 (3,89%) e 49 (8,64%) artigos publicados, a partir dos congressos de 2001 e 2003, respectivamente. A média de publicação dos dois congressos foi de 6,32%. CONCLUSÕES: Os números revelados nessa amostra revelam o quanto a publicação das pesquisas no Brasil é relegada a segundo plano. Muitos trabalhos deixam de ser publicados pela falta de prioridade e tradição em escrever, falta de tempo, empenho e de incentivo.

Differentiation of the honey bee (Apis mellifera L.) antennal lobes during metamorphosis: a comparative study among castes and sexes

In insects the antennal lobes (AL) constitute the brain deutocerebrum. In bees they consist of two neuropil regions, each associated with one antenna, delimited by a layer of glial cells and somata of neurons. The neuropil is organized in distinct globular structures of dense synaptic axons coming from the olfactory organs of the antennae, known as glomeruli. In Apis mellifera, as in other eusocial species of bees, queens, workers, and drones perform different functions in the colony and consequently the organs associated with these functions undergo a differential development. In this paper we analyzed the structure and size of the differentiating AL of queens, workers, and drones during metamorphosis using light microscopy. During metamorphosis the neuropil enlarge and differentiates into concentric structures known as glomeruli. The results showed size, structural and temporal differences in the glomeruli development among the classes of individuals of the colony. The neuropil differentiation starts early and is faster in drones and newly emerged worker is the colony individual class with greater neuropil area in AL. These results are discussed taking in account the functions of the individuals in the colony. (C) Koninklijke Brill NV, Leiden, 2011.

The chemical composition of the mandibular gland secretion of Melipona bicolor lepeletier, 1836 (Hymenoptera, Apidae, Meliponini): A comparative study among castes and sexes

The mandibular gland secretions of newly emerged, nurse and forager workers, virgin and physogastric queens and males of Melipona bicolor were analyzed by gas chromatography-mass spectrometry. The secretion is composed of a blend of hydrocarbons, alcohols, esters, and acids. The secretion is caste-sex specific and also differs with the tasks performed by the workers and the physiological reproductive condition of the queens.

Perfil da atividade de pesquisa publicada nos anais dos congressos brasileiros de pneumologia e tisiologia nos últimos vinte anos

Objective: To increase the knowledge base regarding pulmonology research in Brazil. Methods: A retrospective, observational study of the abstracts published in the Annals of the Brazilian Pulmonology and Phthisiology Conferences held from 1986 to 2004, quantifying the institutions of origin by geographic distribution and type, as well as categorizing the abstracts by study design and topic. Results: A total of 6467 abstracts were published. The institutions of origin were located, variously, in the Southeast (3870 abstracts), South (1309), Northeast (783), Central-West (267) and North (84). There were 94 abstracts originating from foreign institutions, especially from institutions in Portugal (56.3%) and the United States (13.8%). Most of the studies (5825) were conducted in public Brazilian institutions. There were 4234 clinical studies, 1994 case reports and 239 original research articles. A marked, progressive increase was observed in the number of clinical studies and case reports during the period evaluated. Overall, the most common themes were tuberculosis and other infections diseases (25.2%), following by oncology (11.6%), interstitial lung diseases (8.8%) and thoracic surgery (8.5%). Nevertheless, the number of abstracts on each topic varied widely from year to year. Conclusion: Public Brazilian institutions are the principal sources of pulmonology research in Brazil. Such research activity is concentrated in the southeastern part of the country. Case reports account for one-third of this activity. Although there was great variability in the subjects addressed, diseases that are highly prevalent in Brazil, such as tuberculosis and other infections diseases, were the most common topics.

Morpho-structural characterization of rabbits of both sexes in the southeastern region of Brazil

Several studies have highlighted the importance of the correlation between body size and body weight. The objective of this study was to characterize the morphological structure of New Zealand White rabbits, phenotypically correlating body shape traits with body weight. For this purpose, forty rabbits, weaned at 35 days of age, were distributed in a completely randomized experimental design, consisting of two treatments (female and male) with twenty replicates each. At 88 days of age, animals were weighed to determine body weight (B W), and then the following body measures were determined using a measuring tape: ventral perimeter, thoracic perimeter, wither height, croup height, ear length, and body length. Average BW was 2,220 g, and average body measures were 34.4 cm, 28.4 cm, 8.95 cm, 10.4 cm, 10.6 cm, and 36 cm respectively. No significcmt differences between sexes were found relative to the studied traits. There was no negative correlation between body measures and BW, and, except for body length, all measures were significantly correlated with BW, with ear length and ventral perimeter presenting the highest values.

Inactivating Mutations of the Human Luteinizing Hormone Receptor in Both Sexes

The human luteinizing hormone/chorionic gonadotropin receptor (LHCGR) plays a fundamental role in male and female reproductive physiology. Over the past 15 years, several homozygous or compound heterozygous loss-of-function mutations in the LHCGR gene have been described in males and females. In genetic males, mutations in LHCGR were associated with distinct degrees of impairment in pre- and postnatal testosterone secretion resulting in a phenotypic spectrum. Patients with the severe form of LH resistance have predominantly female external genitalia and absence of secondary sex differentiation at puberty. Patients with milder forms have predominantly male external genitalia with micropenis and/or hypospadias or only infertility without ambiguity. The undermasculization is associated with low basal, as well as human CG-stimulated, testosterone levels and elevated LH levels after pubertal age, without abnormal step-up in testosterone biosynthesis precursors. The testes have only slightly reduced size but mature Leydig cells are absent or scarce (Leydig cell hypoplasia). Genetic females with inactivating LHCGR mutations have female external genitalia, spontaneous breast and pubic hair development at puberty, and normal or late menarche followed by oligoamenorrhea and infertility. Estradiol and progesterone levels are normal for the early to midfollicular phase, but do not reach ovulatory or luteal phase levels. Serum LH levels are high whereas follicle-stimulating hormone levels are normal or only slightly increased. Pelvic ultrasound has demonstrated a small or normal uterus and normal or enlarged ovaries with cysts. The inactivating mutations of the LHCGR have provided important insights into distinct physiological roles of LH in reproduction of both sexes.
