Abstract:
Infertility affects 15 % of couples, which corresponds to 60 - 80 million worldwide. The microenvironments in which the oocyte, embryo and fetus mature are vital to the establishment and development of a healthy pregnancy. Different biological systems, such as angiogenesis, the immune system and apoptosis need to be adequately regulated for pregnancy to occur and progress normally. The overall aim of this thesis was to investigate the impact of Histidine-rich glycoprotein (HRG) and Src homology 2 domain-containing adapter protein B (SHB) on human female fertility. HRG is a plasma protein that

Abstract:
Nitrogen (N) fertilization is known to influence the susceptibility of many plants to a variety of diseases. In the case of diseases caused by Botrytis cinerea, the role of N fertilization appears to be variable, with high levels either fostering or reducing severity depending on the studies. To test whether this variability could be due to possible differences in the host plants, inoculum pressure or in the behavior of different strains of the pathogen, studies were carried out to investigate the effect of different N fertilization regimes on the susceptibility of tomato and lettuce to six is

A cana-de-açúcar é uma das principais culturas no cenário nacional e tem grande importância nos fatores econômicos, sociais e ambientais. O nitrogênio é um macronutriente essencial para a planta e a adubação nitrogenada é um manejo de muita importância, mas ao mesmo tempo difícil de se trabalhar devido a suas formas de perdas no solo e na planta. A inoculação com bactérias do gênero Azospirillum em cana-de-açúcar pode ser considerada uma alternativa capaz de contribuir para a sustentabilidade do manejo da adubação nitrogenada e do seu melhor aproveitamento.

Abstract:
The successive use of pig slurry as a soil fertilizer on pasture areas is a common practice in southern Brazil. While there are economic benefits of reuse of waste, this practice poses serious environmental risks and can cause changes in the composition and activity of soil organisms. The soil organisms and microbiological soil quality indicators are very sensitive and allow the monitoring of the soil environment conditions. This work aimed to study the effect of the successive application of pig slurry in pasture areas on the composition, biological activity and microbiological soil quality.

Abstract:
Broadcast spawning marine invertebrates have been widely used as model organisms to study processes of evolution. One of these is the study of various life history stages associated with reproduction. Fertilization ecology in broadcast spawning marine organisms, i.e. the process by which sperm and egg fusion occurs once released into the ocean, has been the subject of intensive study for roughly the last 20 years, and represents thus a recent field in ecological sciences. This growth in interest was sparked by studies that showed spawning events may take place predominantly under sperm limitin

The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa L. cv. 'Vernema'. Field experiments were conducted in 1987 and 1988 at Powell Butte, OR, to determine the effect of five levels of preplant N (0, 10, 20, 40, 60 kg ha⁻¹) on yield and shoot N concentration of alfalfa.

This thesis identifies and elaborates on the way in which notions of genetic inheritance connect with notions of ’proper’ families and hence shape policies concerning reproduction and family formation. Assumptions about the structure and shape of the ’proper’ or ’traditional’ family - as a heterosexual two-parent unit with biological children - and its claim to naturalness, are embedded in policies related to reproductive technologies and family formation. The thesis explores the discourses surrounding the following specific policies - surrogacy, IVF, adoption, abortion, child support and post

Abstract:
Agriculture significantly impacts the global carbon (C) and nitrogen (N) cycles through land use change, soil C loss, greenhouse gas emissions, and increased fixed-N availability. Agriculture occupies a third of the terrestrial biosphere, making understanding its impacts on the C and N cycles critical. I used a novel analytical tool (solid-state 13 C nuclear magnetic resonance spectroscopy) to characterize properties of the C and N cycles in agriculture, including biochemical responses to N fertilizer and agriculture gas fluxes. A central component of the C cycle is the rapid exchange of carbo

The main objective of modern IVF is to maximize the effectiveness of the times to achieve a pregnancy and at the same time also manage the risks, looking for new predictive parameters of the embryonic developmental competence. The analysis of embryo morphodynamic growth is not associated with its euploidy or implantation competence. However, some static parameters of embryo quality might exist that could be associated with embryo competence beyond its chromosomal constitution. The aims of this project are: i) To study from a morphodynamic, genetic and clinical point of view, embryos that show
