1. Three dimensional mathematical modelling of pronuclei migration for the mouse
Sammanfattning : The main question addressed in this thesis is what happens between the moment when the sperm enters the egg and the fusion of the male and the female pronuclei. Orientation of the apposing pronuclei most likely plays a decisive role in the polarity of the developing embryo. LÄS MER
2. Sammanhangets mening : En empirisk studie av livsåskådningar i föreställningar om genteknik och i berättelser om barnlöshet, assisterad befruktning och adoption
Sammanfattning : This present thesis explores the meaning of contexts for views of life. The first aim of the investigation is to describe the existential meaningful content of views of life in perceptions of gene technology and in narratives about childlessness, assisted conception and adoption, as they are articulated in two separate sets of interviews.

3. Towards an integrated ecology through mechanistic modelling of ecosystem structure and functioning
Sammanfattning : Plant physiology, population dynamics and the structure and functioning of ecosystems are closely interrelated. However, these processes are often investigated independently within different subdisciplines of ecology. LÄS MER
4. OVULATION: Intra-ovarian mechanisms
Sammanfattning : Background: Ovulation is the central biological process involved in the menstrual cycle of women. Specifically, ovulation involves the tissue remodelling of the preovulatory follicle to achieve the rupture of the exterior follicle wall with the extrusion of the oocyte. LÄS MER
5. The zebrafish as a model to elucidate human diseases and development
Sammanfattning : This thesis explores the zebrafish as a model organism to illuminate our understanding of processes that orchestrate the progression of cancer metastasis and myogenesis. First, I describe the successful establishment of a cancer metastasis model in the zebrafish, specifically to study intravasation - one of the earliest steps in the metastatic cascade. LÄS MER
