1. 1. Maternal programming: costs, benefits and constraints of maternal hormone transfer

   Författare :Michael Tobler; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; aves; immune function; behavior; Maternal effects; hormones;

   Sammanfattning : Avian mothers convey significant quantities of androgens (i.e. ?male? steroids) to their eggs, which are known to positively influence embryonic development, post-natal growth and competitive behaviour of the offspring. However, there is large inter-female variation in the amount of androgens transferred to the eggs. LÄS MER

3. 2. Polybrominated dibenzo-p-dioxins : Natural formation mechanisms and biota retention, maternal transfer, and effects

   Författare :Kristina Arnoldsson; Peter Haglund; Patrik Andersson; Walter Vetter; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polybrominated dibenzo-p-dioxins; PBDDs; Baltic Sea; uptake; retention; maternal transfer; metabolism; bioavailability; natural formation; precursor; bromoperoxidase; bromophenol; photochemical transformation; oxidative coupling; hydroxylated polybrominated diphenyl ethers; Chemistry; Kemi; analytisk kemi; Analytical Chemistry;

   Sammanfattning : Polybrominated dibenzo-p-dioxins (PBDD) and dibenzofurans (PBDF) are a group of compounds of emerging interest as potential environmental stressors. Their structures as well as toxic responses are similar to the highly characterized toxicants polychlorinated dibenzo-p-dioxins. LÄS MER

4. 3. Safety and quality aspects of IVF - neonatal and maternal outcomes following advanced techniques

   Författare :Erica Ginström Ernstad; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blastocyst transfer; frozen embryo transfer; vitrification; preimplantation genetic testing; neonatal outcome; maternal outcome;

   Sammanfattning : Background: Singletons born following assisted reproductive technology (ART) have adverse neonatal outcome compared to singletons born following spontaneous conception (SC). Moreover, the women undergoing ART are at an increased risk of hypertensive disorders in pregnancy (HDP) and placental complications. LÄS MER

5. 4. Obstetric outcome after single embryo transfer

   Författare :Antonina Sazonova; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in-vitro fertilization; single embryo transfer; neonatal outcome; maternal outcome;

   Sammanfattning : Obstetric outcome after single embryo transfer Department of Obstetrics and Gynecology, Institute of Clinical Sciences, The Sahlgrenska Academy, University of Gothenburg, SE-413 45 Gothenburg, Sweden. Background: Children born after IVF have a poorer neonatal outcome than children born after spontaneous conception, even after adjustment for confounders. LÄS MER

7. 5. Elective single embryo transfer

   Författare :Ann Thurin-Kjellberg; Göteborgs universitet; []
   Nyckelord :In vitro fertilization; elective single embryo transfer; multiple pregnancies; randomized; controlled trial; prediction of IVF outcome; embryo selection; cost-effectiveness analysis;

   Sammanfattning : The aim of the study was to evaluate if the elective single embryo transfer (eSET) strategy couldmaintain delivery rates, with at least one live born child, and at the same time decrease the rate ofmultiple births. A cost-effectiveness analysis was also performed between the elective single embryotransfer (SET) (1+1) and double embryo transfer (DET) (2+0) strategies. LÄS MER
