Início da função gonadal no sagui comum (Callithrix jacchus): diferenças entre gêneros

Os primatas não humanos, como Callithrix jacchus vêm sendo utilizados com maior frequência em pesquisa biomédica e, recentemente, nosso laboratório propôs uma nova classificação para monitorar com mais detalhes as modificações comportamentais e hormonais relacionadas ao desenvolvimento. O presente trabalho monitorou os níveis de hormônios gonadais de 4 machos e 6 fêmeas de C. jacchus durante as fases juvenil I e II e subadulta (dos 5 aos 15 meses). Os resultados apontaram que os níveis de progesterona nas fêmeas e andrógenas nos machos foram estatisticamente mais elevados nos estágios juvenil II e subadulto, respectivamente, em relação ao estágio juvenil I. Estes achados indicam que, de acordo com a nova classificação, foi possível observar que o funcionamento gonadal se instala mais cedo nas fêmeas

Changes in peak expiratory flow and respiratory strength during the menstrual cycle

This study evaluated the spirometry and respiratory static pressures in 17 young women, twice a week for three successive ovulatory menstrual cycles to determine if such variables changed across the menstrual, follicular, periovulatory, early-tomid luteal and late luteal phases. The factors phases of menstrual cycle and individual cycles had no significant effect on the spirometry variables except for peak expiratory flow (PEF) and respiratory static pressures. Significant weak positive correlations were found between the progesterone:estradiol ratio and PEF and between estrogen and tidal volume (r = 0.37), inspiratory time (r = 0.22), expiratory time (r = 0.19), maximal inspiratory pressure (r = 0.25) and maximal expiratory pressure (r = 0.20) and for progesterone and maximal inspiratory pressure (r = 0.32) during the early-to-mid luteal phase. Although most parameters of the spirometry results did not change during the menstrual cycle, the correlations observed between sexual hormones and respiratory control variables suggest a positive influence of sexual female hormones controlling the thoracic pump muscles in the luteal phase

O papel sócio empreendedor da ONG Sodireitos em defesa dos direitos sexuais e migratórios na Amazônia

This paper presents a case study from the Society for the Defense of Sexual and Migrate Rivers Amazônia - Sodireitos, whose central problem is to understand how it the works the social entrepreneur of the NGO Sodireitos in defense of sexual rights and migrate rivers in Amazônia. The central objective is to analyze the practices Social Entrepreneurship at the NGO Sodireitos on sexual rights and migrate rivers. The method adopted examined the entire creation process at the NGO the present day. Primary and secondary dates were used allowing the viewing of the dynamic intervention Social Sodireitos practiced by the fields of human rights and migrate rivers.

Femininos de montar - Uma etnografia sobre experiências de gênero entre drag queens

The paper presents a discussion about gender and body in the drag queens experience at Natal city (RN). From the different concepts that characterizes the identity processes on subjects who perform gender transformation (transvestites, transsexuals and female impersonators), the justification for studying the drag character is observed as a means to understand matters that are important when you take such a position. Therefore, there is a need for a linkage between the various concepts responsible for this definition, in addition to considering the historical and cultural process responsible for the creation of such categories, identities and stereotypes among these individuals. In this sense it will be possible to carry out a critical analysis on the different social loads present in each representation, and understand what is at stake in the attribution of classifications and terminologies that are applied to different expressions of metamorphosis. This ethnography considers the debate from a field research conducted at LGBT social establishments and other performance spaces of these people, verifying their dynamics in these places and investigating relationships between performers, personas and characters and also backstage scene in which they participate
