1. DNA methylation, environmental exposures and early embryo development
Abstract The first crucial step in the developmental program occurs during pre-implantation, the time after the oocyte has been fertilized and before the embryo implants in the uterus. This period represents a vulnerable window as the epigenome undergoes dynamic changes in DNA methylation profiles. Alterations in the early embryonic reprogramming wave can im

2. Immunohistochemical localization of progesterone receptors alpha (PRA) in ovary of the pseudopregnant rabbit
Abstract Progesterone plays an important role in the reproductive function and follicular development in mammals. The aim of the present study was to examine the localization of progesterone receptor alpha (PRA) in ovary of pseudopregnant rabbit by immunohistochemical methods. Samples were collected from 14 h. to 18 days of pseudopregnancy. At the first stag

3. Morphological changes of gonad and gene expression patterns during desexualization in Dugesia japonica (Platyhelminthes: Dugesiidae)
ABSTRACT Planarians, the representatives of an ancient bilaterian group with complex reproductive system and high regenerative capabilities, are model system suitable for studying the basic molecular requirements for the development of the reproductive system. To further explore the morphological changes of the gonads during desexualization and the molecular

4. Flow Analysis: Looking Back and Forward
Flow analysis changed significantly the way of performing chemical analysis by (i) mechanization of analytical procedures in a continuous flowing stream with minimal sample intercontamination; (ii) analytical measurements without attaining chemical equilibria, thus increasing the applicability of kinetic methods and allowing the exploitation of non-quantitat

5. Source-sink relationships in two soybean cultivars with indeterminate growth under water deficit
Abstract Water deficit is a major factor limiting crop yield in rainfed areas. We hypothesized that under water deficit the decrease of photosynthetic production stimulates: carbohydrate remobilization from leaves, stems and roots to reproductive organs; and decreasing flowering intensity and pod development. The present work aims to study the effect of wate

6. Determination of limited histotrophy as the reproductive mode in Mustelus schmitti Springer, 1939 (Chondrichthyes: Triakidae): analysis of intrauterine growth of embryos
ABSTRACT This work analyzed length-mass relationship, growth in length, mass variations and dynamic of yolk sac depletion of Mustelus schmitti embryos, extracted from females catched by the artisanal fishery acting off La Paloma (34°39'S, 54°10'W, Uruguay) during 2006 and 2007. Differences in total length and total mass between sexes were not significant.

7. Feminismo, Iglesia Católica y derechos sexuales y reproductivos en el Chile post-dictatorial
In the last decades, sexuality and reproduction have become areas of disputes between antagonistic actors, generating a regional dynamic of advances and retreats on the sexual and reproductive rights agenda. In Chile, many reforms in these areas have been stopped by conservative opposition, while others simply have not even become publicly discussed. Current

9. The resigned qualification: the bad formation of workforce how a structural problem of Brazilian development / A qualificação resignada : A má formação da força de trabalho como um problema estrutural do desenvolvimento brasileiro
This work makes a diagnosis of training policy and professional education system in Brazil. The subject had never been so professional education on the agenda in the sociology of work and labor economics, but came to light at the end of the twentieth century, when the new stage of accumulation explained the decline of Fordism-Taylorism, also denouncing the n

12. Perfil demográfico e estimativas de paridade dos Guarani nas regiões Sul e Sudeste do Brasil / Demographic profile and parity estimation of Guarani in South and Southeast regions of Brazil
The indigenous people in Brazil and Latin America are in a population growth process, in spite of pessimists forecasts which indicated their disappearance. In the last decades, the native Brazilian population has grown, in mean, 3.5% per year, more than the double the national mean, which is due to the high fecundity regimen and moderate mortality. The Guara
