  1. 26. THE ANDROGEN RECEPTOR GGN POLYMORPHISM. Genetic and functional analyses

    Författare :Kristina Lundin; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Functional domain; Genetic predisposition; Reproductive function; Sex hormone; Transactivation function; Repeat; Polymorphism; Androgen receptor; Transcription factor; Medicin människa och djur ; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Male sex development and reproductive function is regulated by androgens acting via the androgen receptor (AR). The AR harbours two polymorphic repeats of CAG and GGN triplets, encoding glutamines and glycines, respectively. LÄS MER

  3. 27. Outcome and prevention strategies in peritoneal adhesion formation

    Författare :Fanny Fredriksson; Helene Lilja; Bobby Tingstedt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peritoneal adhesion prevention; inflammatory cytokines; experimental adhesion model; adhesive small bowel obstruction; adhesion-related morbidity; Barnkirurgi; Pediatric Surgery;

    Sammanfattning : Peritoneal adhesions occur in up to 93% of adults after peritoneal trauma during surgery. Most adhesions are asymptomatic but can cause female infertility, small bowel obstruction (SBO) and chronic abdominal pain. Adhesion prophylaxis is needed to reduce the significant morbidity and increased health care costs resulting from peritoneal adhesions. LÄS MER

  4. 28. Female genital mutilation : determinants and consequences among girls and women in Sudan

    Författare :Sozan Elmusharaf; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Female genital mutilation (FGM) is still a reality in Sudan, Egypt and sub-Saharan Africa with three million girls at risk of being subjected to the practice annually and approximately 140 million girls and women currently living with its consequences worldwide. Five hospital-based studies were conducted in Khartoum state, Sudan, with the following aims: (I) To investigate the association between FGM and primary infertility. LÄS MER

  5. 29. Growth factors in spermatogenesis

    Författare :Aida Wahlgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Testis; seminiferous tubules; proliferation; growth factors; sex steroids;

    Sammanfattning : The aim of this study was to increase the knowledge of die effects of locally produced growth factors and hormones on germ cell proliferation in rat testis in vitro. Since impaired sperm production and function accounts for half the cases of infertility, it is important to understand the physiological actions in germ cell development. LÄS MER

  7. 30. ELOVL2 and PUFA biosynthesis : Impact on sex-specific processes in mammals

    Författare :Amanda González-Bengtsson; Anders Jacobsson; Christian Drevon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysiologi; Physiology;

    Sammanfattning : Endogenously synthesized PUFAs (Polyunsaturated Fatty Acids) vary in production depending on medical conditions, gender, developmental phase, age, fertility status, pregnancy and lactation. PUFA biosynthesis is further regulated via amount of dietary intake as well as genetically. LÄS MER
