  1. 1. Three dimensional mathematical modelling of pronuclei migration for the mouse

    Författare :Sofia Tapani; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fertilisation process; pronucleus; dynamical simulation; SDE; correlation; CUSUM; microtubule; confocal microscopy; dynamical simulation;

    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

  3. 2. Sammanhangets mening : En empirisk studie av livsåskådningar i föreställningar om genteknik och i berättelser om barnlöshet, assisterad befruktning och adoption

    Författare :Katarina Westerlund; Carl Reinhold Bråkenhielm; Susanne Lundin; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Faiths and ideologies; view of life; life-philosophy; world-view; context; meaning in life; genetics; gene technology; childlessness; in-vitro-fertilisation; adoption; Tros- och livsåskådningsvetenskap; Faith and reason; Tros- och livsåskådningsvetenskap; tros- och livsåskådningsvetenskap; Studies In Faiths and Ideologies;

    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.

  4. 3. Towards an integrated ecology through mechanistic modelling of ecosystem structure and functioning

    Författare :Thomas Hickler; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; geomorphology; Physical geography; integrated ecology; plant hydraulic architecture; climate change; CO2 fertilisation effect; biogeography; biogeochemistry; vegetation dynamics; ecosystem modelling;

    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

  5. 4. OVULATION: Intra-ovarian mechanisms

    Författare :Farnosh Sørensen Zakerkish; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovulation; Human;

    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

  7. 5. The zebrafish as a model to elucidate human diseases and development

    Författare :Samantha Lin Chiou Lee; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    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
