Abstract: the work was carried out to assess mass production and nutritional content of winter forages using lopsided oat (avena strigosa) and white oat (avena sativa) intercropped with ryegrass (lolium multiflorum) and vetch (vicia sativa l.). the species were intercropped as the following treatments: lopsided oat with ryegrass (lo+rg); white oat with ryegrass (co+rg); lopsided oat with vetch (lo+v); white oat with vetch (co+v); lopsided oat, vetch and ryegrass (lo+rg+v); and white oat, ryegrass and vetch (co+rg+v). the study evaluated total forage mass production of each intercropping and crude protein levels, neutral detergent fiber and in vitro digestibility coefficient of dry matter. the results indicate that forage yield of oats was higher in early assessments, and ryegrass and vetch were higher in the final evaluation period. the crude protein levels and neutral detergent fiber were higher at the start of the experiment for all evaluated treatments, and those including vetch intercropped with oats showed an increase in these parameters in the final period due to the presence of vetch, which has a more delayed cycle.

Abstract: A planície de inunda o do alto rio Paraná caracteriza-se pela grandediversidade de organismos aquáticos e as larvas de Chironomidae destacam-se por sua elevada abundancia. A partir da hipótese de que as variáveis abióticas influenciam a composi o, densidade e dominancia das larvas de Chironomidae em diferentes ambientes eperíodos amostrados, este trabalho objetivou: caracterizar o rio Baía, canal secundário, lagoa n o-conectada (Fechada) e lagoa conectada (Guaraná) da planície de inunda o do alto rio Paraná, de acordo com os atributos da assembléia de Chironomidae e identificar possíveis gradientes de distribui o espacial e temporal das larvas, relacionando-as com algumas variáveis abióticas. As coletas foram realizadas no período de mar o de 2003 a dezembro de 2005, em três pontos distintos (margens e centro), com o auxílio de um pegador tipoPetersen modificado. A Análise de Correspondência Can nica mostrou que as larvas foram influenciadas principalmente pela textura granulométrica do sedimento. O canal Curutuba, pela presen a de seixos, diferenciou-se das demais esta es de coleta como rio Baía e as lagoas de inunda o onde predominaram as partículas mais finas. Pode-se concluir que a composi o granulométrica, a porcentagem de matéria organica presente no sedimento e a hidrodinamica de cada ambiente foram os principais fatores que influenciaram a distribui o espacial das larvas de Chironomidae. The floodplain of the upper Paraná river is characterized by the great diversity of aquatic organisms, and the larvae of Chironomidae are distinguished for their high density. Starting from the hypothesis that abiotic variables influence Chironomidae larvae composition, density and dominance in different environments and sampled periods, this study aimed to characterize the Baía river, secondary channel, floodplain lakes (connected and non-connected) of the Paraná river floodplain, according to attributes of Chironomidae assemblage, and identify possible gradients of temporal and spatial distribution of the larvae, relating them with abiotic variables. The collections were carried out from March 2003 to December 2005. Samples were collected in three points (margins and center), using a modified Petersen grab. CCA showed the larvae were influenced mainly by sediment particle size. Curutuba channel, due to the presence of pebbles, differed from other sites such as the Baía river and floodplain lakes, where fine particles predominated. It was concluded that particle size composition, percentage of organic matter andhydrodynamic of each environment were the

Abstract: pesticides are widely used in agriculture, and the widespread application of these agents, without the appropriate use of bio-security measures, has been causing potential impacts for environmental degradation, as well as for the human organism, increasing the incidence of occupational poisoning. the aim of the present study was to review the available literature and to carry out a discussion regarding pesticides exposure and its harmful effects on the auditory system's function and structure. relevant national and international journals indexed in pubmed, medline, bireme and lilacs were reviewed, as well as book chapters and dissertations published between 1987 and 2009. the available data suggest that chronic exposure to pesticides lead to functional alterations in the vestibulocochlear system, as well as a series of signs and symptoms. in spite of the scarce data describing organophosphorus influence on morphological characteristics of the auditory system, the literature suggest that acute exposure to pesticides can also be responsible for auditory system alterations, characterized by structural lesions in the cochlea, mainly in outer hair cells.

Abstract: Com o objetivo de estimar e comparar a diversidade e flutua o populacional das famílias de Hymenoptera em área de restinga foi realizado um levantamento faunístico em duas áreas de restinga com diferentes níveis de conserva o. Foram coletados 5.518 himenópteros distribuídos em 30 famílias. Os picos populacionais na flutua o das famílias ocorreram no ver o confirmando a alta correla o da temperatura com a distribui o das famílias. Constatou-se na restinga em sucess o maior riqueza, porém, com alta dominancia, abrigando representantes dos três grupos ecológicos (antófilos, generalistas e parasitóides) em alta abundancia. A restinga preservada, com 17 famílias, verificou-se mais diversa e homogênea, onde verificou-se maior abundancia dos parasitóides, devido à maior estabilidade do sistema. A riqueza de famílias de Hymenoptera em áreas de restinga pode ser utilizada como parametro indicativo de qualidade ambiental, para este tipo de bioma.Hymenoptera Families (Insecta) as Evaluation Tool of the Conservation of Sandbanks in Southern BrazilAbstract. With aim to estimate and compare the diversity and population of the Hymenoptera families in a sandbank area was carried out a wildlife survey in two areas of sandbank with different levels of conservation. We collected 5 518 Hymenoptera distributed in 30 families. The peaks in the families fluctuation occurred in the summer confirmed the high correlation of temperature with the distribution of families. The sandbank in succession had the highest richness, however with high dominance, hosting representatives of the three ecological groups (anthophilous, generalists and parasitoids) in high abundance. The sandbank preserved, with 17 families, was more diverse and homogeneous, where the parasitoids showed greater abundance due to greater system stability. The richness of Hymenoptera families in sandbanks can be used as a parameter indicative of environmental quality.

Abstract: congenital isolated hypogonadotropic hypogonadism (ihh) is characterized by partial or complete lack of pubertal development due to defects in migration, synthesis, secretion or action of gonadotropin-releasing hormone (gnrh). laboratory diagnosis is based on the presence of low levels of sex steroids, associated with low or inappropriately normal levels of pituitary gonadotropins (lh and fsh). secretion of other pituitary hormones is normal, as well magnetic resonance imaging of the hypothalamohypophyseal tract, which shows absence of an anatomical defects. when ihh is associated with olfactory abnormalities (anosmia or hyposmia), it characterizes kallmann syndrome. a growing list of genes is involved in the etiology of ihh, suggesting the heterogeneity and complexity of the genetic bases of this condition. defects in olfactory and gnrh neuron migration are the etiopathogenic basis of kallmann syndrome. mutations in kal1, fgfr1/fgf8, prok2/prokr2, nelf, chd7, hs6st1 and wdr11 are associated with defects in neuronal migration, leading to kallmann syndrome. notably, defects in fgfr1, fgf8, prokr2, chd7 and wdr11 are also associated with ihh, without olfactory abnormalities (normosmic ihh), although in a lower frequency. mutations in kiss1r, tac3/tacr3 and gnrh1/gnrhr are described exclusively in patients with normosmic ihh. in this paper, we reviewed the clinical, hormonal and genetic aspects of ihh.
