11. Human exposure to persistent organic pollutants : Illustrated by four case studies in Europe
Sammanfattning : An extensive use of chemicals in countless consumer products has resulted in human exposure to several persistent organic pollutants (POPs). Sufficient knowledge about their chemical composition properties and environmental faith is required, to be able to proper risk assess and regulate the substances. LÄS MER
12. Structure and distribution of alpha-1-microglobulin proteins
Sammanfattning : This thesis describes studies of the structure and tissue distribution of alpha-1-microglobulin (a1-m), a member of the lipocalin protein superfamily with immunosuppressive properies. It was shown that a1-m appears in human plasma in five major forms. LÄS MER
13. Nitric oxide synthase in female reproductive and urinary organs: Hormonal regulation and functional significance
Sammanfattning : Nitric oxide synthase (NOS) activity was studied in cytosolic and particulate fractions in reproductive organs from rabbit (uterus and vagina) and rat (uterus, vagina and cervix). NOS was found predominantly in cytosolic fractions in all tissues and the activity of NOS in both fractions was highly Ca2+ dependent. LÄS MER
14. Regulation of Ovarian Aromatase: Studies by Aromatase Assays in vitro and in vivo
Sammanfattning : An in vitro method was developed for measuring aromatase, based on binding of competitive aromatase inhibitor [11C]vorozole to the active site of the enzyme. [11C]Vorozole displayed high, specific binding in vitro to human placenta and human granulosa cells (GC), both fresh and frozen/thawed cells, provided correct procedures were used. LÄS MER
15. Exosomes and the NKG2D receptor-ligand system in pregnancy and cancer : using stress for survival
Sammanfattning : Although not obvious at first sight, several parallels can be drawn between pregnancy andcancer. Many proliferative, invasive and immune tolerance mechanisms that supportnormal pregnancy are also exploited by malignancies to establish a nutrient supply andevade or edit the immune response of the host.
