    Abstract : Recent research demonstrated that besides a role in sex determination and male fertility, the Y chromosome is involved in additional functions including prostate cancer, sex-specific effects on the brain and behaviour, graft-versus-host disease, nociception, aggression and autoimmune diseases. The results presented in this thesis include an analysis of sex-biased genes encoded on the X and Y chromosomes of rodents. READ MORE

  4. 7. Human endometrial receptivity and embryo-endometrium interactions

    Author : Signe Altmäe; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Infertility is an increasing medical and social problem affecting more than 10% of couples worldwide. Many underlying causes of human infertility have been overcome by assisted reproductive techniques; nevertheless, the implantation process remains one of the rate-limiting step as regards the success of the treatment.

    Author : Elo Madissoon; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Millions of couples worldwide have difficulties in conceiving a child. These couples, affected by infertility, suffer from symptoms of stress. The causes of infertility are largely unknown and current available treatment, in vitro fertilization has moderate success rates. READ MORE

  6. 9. Generation of midbrain dopaminergic neurons in vivo and in vitro: the role of Neurogenin2

    Author : Elin Andersson; Neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Medicin människa och djur ; cell replacement; Parkinson?s; dopamine; neuronal specification; development; mesencephalon; TH; neuronal differentiation; proneural genes; transcription factors; bHLH; neurospheres; stem cell; progenitor cell;

    Abstract : Parkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. READ MORE

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

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

    Abstract : 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. READ MORE
