1. 6. Fetal Outcome in Experimental Diabetic Pregnancy

   Författare :Sheller Zabihi; Ulf Eriksson; Michael Welsh; Elisabeth (Lisa) Persson; Uppsala universitet; []
   Nyckelord :Cell biology; Rat; Mouse; TG; KO; Diabetes in Pregnancy; Embryo; Folic acid; Superoxide dismutase; Catalase; Glutathione peroxidase; Vascular endothelial growth factor-A; Folate binding protein-1; Bax; Bcl-2; Caspase-3; P53; Pax-3; Blood flow; Cellbiologi;

   Sammanfattning : Women with pregestational diabetes have a 2-5 fold increased risk of giving birth to malformed babies compared with non-diabetic women. Diabetes-induced oxidative stress in maternal and embryonic tissues has been implicated in the teratogenic process. LÄS MER

3. 7. Studies on in vitro fertilised human preembryos. Morphological and chromosomal aspects

   Författare :Thorir Hardarson; Göteborgs universitet; []
   Nyckelord :IVF; oocyte; embryo; blastocyst; human; FISH; aneuploidy;

   Sammanfattning : The success rate of in vitro fertilisation (IVF) has gradually increased due to basic research in preembryonic biology and the introduction of new methods, both technical and medical. However, further research is needed to establish which preembryos are developmentally most competent in order to be able to maintain the pregnancy rate while only a single preembryo is being transferred.

4. 8. Yolk sac morphology and uterine blood flow are associated with fetal outcome in diabetes pregnancy

   Författare :Sheller Zabihi; Uppsala universitet; []
   Nyckelord :Diabetes; yolk sac; embryo; gene expression; blood flow; folic acid; SOD; apoptosis;

   Sammanfattning : Women with pregestational diabetes have a 3-5 times increased risk of giving birth to malformed babies compared with non-diabetic women. The malformations are likely to be induced before the seventh week of pregnancy, when the yolk sac is partly responsible for the transfer of metabolites to the embryo, and the uterine blood flow to the implantation site determines the net amount of nutrients available to the conceptus.

5. 9. Cumulative Live Birth Rates after In Vitro Fertilization

   Författare :Catharina Olivius; Göteborgs universitet; []
   Nyckelord :in vitro fertilization; cumulative live birth; single embryo transfer; frozen-thawed cycle; discontinuation;

   Sammanfattning : Background: In vitro fertilization (IVF) has become increasingly common, today representing about 3% of all live births in some countries. Most patients have to undergo more than one treatment in order to achieve a live birth. Thus cumulative live birth rates are highly interesting to the patients. LÄS MER

7. 10. GM-CSF. A regulator of pre-implantation embryo development

   Författare :Cecilia Sjöblom; Göteborgs universitet; []
   Nyckelord :GM-CSF blastocyst embryo culture cytokine growth factor GM-CSF receptor glucose transport apoptosis;

   Sammanfattning : GM-CSF is a multifunctional cytokine expressed in abundance in the female reproductive tract during early pregnancy. We have investigated the regulatory influence of GM-CSF in development of pre-implantation mouse and human embryos. LÄS MER
