  2. 6. New micromanipulative techniques in reproductive biology

    Author : José Inzunza; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : New micro manipulative techniques have facilitated development to help patients who suffer from infertility and spontaneous abortion, as well as those who carry severe genetic diseases and have risks of delivering an affected child. Preimplantation genetic diagnosis (PGD), which is based on obtaining blastomere biopsy from an eight-cell embryo, has made it possible to diagnose severe defects caused by a genetic factor.

  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.

  5. 8. Chromatin and transcriptome-based integrative approaches to profile functional long noncoding RNAs - A computational approach

    Author : Santhilal Subhash; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computational biology; Long noncoding RNAs; Chromatin; S-phase; Cell cycle; sperm; Epigenetics; Histone; cancer; oncogene; Tumor suppressor; DNA methylation; Histone modifications; Chromatin remodelers; lncRNAs; lincRNAs;

    Abstract : One of the major hallmarks of cancer is aberrant or uncontrollable cell division, which occurs due to a defective cell cycle process. During the synthesis phase (S-phase) of the cell cycle, before cell division or mitosis phase, the DNA in the cell makes a new copy to pass on genetic information to the daughter cells. READ MORE

  6. 9. Molecular mechanisms of ovarian follicular development and early embryogenesis

    Author : Nagaraju Gorre; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ovary; primordial follicles; Embryogenesis; PI3K-mTORC1 signaling;

    Abstract : In the mammalian ovary, the dormant primordial follicles are the source of developing follicles and fertilizable ova for the entire reproductive life. In addition, the duration of fertility of a female is determined by the initial size of her pool of primordial follicles and by the rate of its activation and depletion. READ MORE

  7. 10. Cell transplantation and immunoisolation : studies on a macroencapsulation device

    Author : Ehab Rafael; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Encapsulation of cellular grafts in semipermeable membranes may provide a way to protect the graft from immune attack without the need for pharmacological immunosuppression. In this thesis, the use of immunoisolating devices consisting of a bilaminar PTFE membrane was evaluated. READ MORE
