  2. 1. Role of estrogen receptor beta in epithelia lacking estrogen receptor alpha expression

    Author : Andrea Morani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Estrogen Receptors; Extracellular Matrix; Prostate Cancer; Lung Diseases; Ovarian Follicle;

    Abstract : Estrogens influence the physiology of many organs by activation of the nuclear receptors ERalpha and ERbeta. The epithelium of ventral prostate, ovarian granulosa cells and lung, are ERalpha-negative but express high levels of ERbeta. This thesis focuses on the role played by ERbeta in ERalpha-negative epithelium. READ MORE

  4. 2. Epigenetic Regulation of Replication Timing and Signal Transduction

    Author : Rosita Bergström; Aristidis Moustakas; Carl-Henrik Heldin; Rolf Ohlsson; Alain Mauviel; Uppsala universitet; []
    Keywords : Cell and molecular biology; Chromatin; CTCF; Epigenetics; Genomic Imprinting; H19; Id; Igf2; Insulator; Replication; Signal Transduction; Smad; TGF-β; Transcription; Cell- och molekylärbiologi;

    Abstract : Upon fertilization the paternal and maternal genomes unite, giving rise to the embryo, with its unique genetic code. All cells in the human body are derived from the fertilized ovum: hence they all contain (with a few exceptions) the same genetic composition. READ MORE

  5. 3. Assessment of tubal infertility with radionuclide-labelled particles and falloscopy

    Author : Steffan Lundberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : fallopian tube; falloposcopy; hysterosalpingography; radionuclide hysteropingography; tubal infertility; tubal investigation; tubal transport;

    Abstract : The fallopian tubes are of central importance for human reproduction in vivo. Damage to the tubal internal mucosa can result in disturbance of sperm and ovum transport. About 40% of infertile women have tubal disease as their main cause of infertility. READ MORE

  6. 4. Considering a Baby? Responsible Screening for the Future : Ethical and social implications for implementation and use of preconception expanded carrier screening in Sweden

    Author : Amal Matar; Anna T Höglund; Mats G. Hansson; Lars Sandman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preconception expanded carrier screening; reproductive autonomy; solidarity; popula-tion screening; genomics; ELSI;

    Abstract : Preconception expanded carrier screening is a novel technology that involves the offer of a screening test for many recessive diseases (via an expanded screening panel) to prospective parents, with no priori risk. Test positive couples have a number of reproductive choices; prenatal diagnosis and aborting affected fetus, IVF and preimplantation genetic diagnosis, sperm or ovum donation or simply accept the risk.

  7. 5. Human gonadotrophins for ovarian stimulation in infertility treatment

    Author : Jonas Harlin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Infertility problems are present in 10 to 15 % of couples of fertile age. Ovulatory dysfunction, as a single cause, can be successfully treated and in-vitro fertilisation (IVF) can help a considerable number of couples, also when male problems are present. READ MORE
