2. 1. Reproductive toxicology of endocrine disruptors : effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis

   Author : David Gunnarsson; Gunnar Selstam; Gunnar Nordberg; Per Leffler; Henrik Leffers; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Endocrine disruptors; reproductive toxicology; cadmium; phthalates; DEHP; MEHP; phytoestrogens; steroidogenesis; testosterone; Leydig cell; Molecular biology; Molekylärbiologi;

   Abstract : A number of investigations during the last two decades describe adverse trends in male reproductive health, which have been proposed to be caused by environmental factors with endocrine disrupting properties. In contrast to many other toxicants, endocrine disruptors often do not show linear dose-response relationships typical of those found in traditional toxicological studies. READ MORE

4. 2. Biological Markers of Fertility

   Author : Sarah Nordqvist; Helena Åkerud; Karin Kårehed; Agneta Skoog Svanberg; Anneli Stavreus-Evers; Geraldine Hartshorne; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; embryogenesis; female reproductive tract; fertility; fertilization; Histidine-rich glycoprotein; intron; in vitro fertilization; oocyte; ovarian response; pregnancy; single nucleotide polymorphism; Src homology 2 domain-containing adapter protein B;

   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. READ MORE

5. 3. G protein-coupled estrogen receptor 1 (GPER) in the female reproductive tract: from physiology to cancer

   Author : Zuzana Kolkova; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Estrogen effects are mediated either through genomic action involving the classical estrogen receptors, estrogen receptor alpha (ERα) and beta (ERß), which function as transcription factors in the nucleus, or through rapid non-genomic action via receptors associated with plasma membrane. Recently, a member of the G protein-coupled receptor family was ascribed estrogen receptor properties and proposed as a candidate for mediating non-genomic estrogen signaling. READ MORE

6. 4. Host epithelium integrity in the female reproductive tract during Neisseria gonorrhoeae infection

   Author : Linda Weyler; Helena Aro; Lene Rasmussen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Female reproductive tract; Neisseria gonorrhoeae; VK2 E6E7 cells; DNA damage; cell cycle; mitosis; restriction endonucleases; infection models; molekylär biovetenskap; Molecular Bioscience;

   Abstract : Neisseria gonorrhoeae infections are asymptomatic in approximately fifty percent of the affected women. Left untreated, this can develop into a long-term inflammatory state with detrimental secondary complications such as ectopic pregnancy and sterility. Furthermore, studies have shown that N.

7. 5. Aspects of biliary tract cancer : incidence and reproductive risk factors

   Author : Carl Kilander; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Biliary tract cancer, including cancer of the extra-hepatic bile ducts, cancer of the Ampulla of Vater and gallbladder cancer, is a devastating disease with poor prognosis. The incidence of biliary tract cancer is decreasing worldwide, for unknown reasons. READ MORE
