2. 16. Factors of importance for the outcome of IVF-treatment in women with tubal infertility

   Author : György Csemiczky; Karolinska Institutet; Karolinska Institutet; []
   Keywords : In vitro fertilization; grade of tubal damage; extent of reconsructive surgery; E2; P4; prognostic factors; ovarian failure; endometrium; implantation.;

   Abstract : In vitro fertilization embryo transfer (IVF-ET) is a well-established infertility treatment caused by damage of the fallopian tube, which is one of the largest diagnostic categories in most IVF programs. This study evaluates factors of importance for the outcome of IVF-treatment: age, tubal damage grade, extent of reconstructive surgery, endocrine ovarian function and endometrial development.

4. 17. Prenatal diagnosis in routine antenatal care : a randomised controlled trial

   Author : Sissel Saltvedt; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Ultrasound; fetal ultrasonography; Down s syndrome; chromosomal disorder; nuchal translucency; genetic screening; prenatal diagnosis; abnormalities; gestational age; in vitro fertilization; fetometry; dating formulas; false positive reactions; anxiety;

   Abstract : Nuchal translucency (NT) measurement combined with maternal age has been shown to identify women at an increased risk of carrying a fetus with Down's syndrome (DS) more accurately than does maternal age alone. The aim of this study was to evaluate more widely the effects of two different strategies for prenatal diagnosis. READ MORE

5. 18. Polyandry and the evolution of reproductive divergence in insects

   Author : Tina Nilsson; Göran Arnqvist; David Hosken; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Bruchidae; cryptic female choice; multiple mating; sexual conflict; sexually antagonistic coevolution; sexual selection; speciation; sperm competition; Tenebrionidae; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Abstract : Multiple mating by females is common in nature. Yet, the evolution and maintenance of polyandry remains a bit of an evolutionary puzzle. It was my aim in this thesis to reach a greater understanding of this phenomenon as well as to investigate the consequences of polyandry on the evolution of reproductive divergence in insects.

6. 19. Mechanisms and regulations of priming effects in soil

   Author : Jian Li; MEMEG; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Soil organic matter (SOM) plays a significant role in the global carbon (C) and nutrients cycles, not only since SOM is a major storage reservoir of C and plant nutrients, but also since microbial decomposition of SOM releases large quantities of CO2 to the atmosphere. The accelerated or reduced turnover rate of SOM after the input of labile C compounds is a phenomenon known as the priming effect (PE). READ MORE

7. 20. Management of severe male infertility with special reference to IVF and ICSI

   Author : Björn Rosenlund; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: Until recently the treatment options for couples with severe male factor infertility have been restricted. With the advent of intracytoplasmic sperm injection (ICSI) it has now become possible to offer these couples effective treatment. READ MORE
