  1. 1. Recurrent spontaneous abortion : a clinical, immunological and genetic study

    Författare :Barbara Jablonowska; Ole Christiansen B.; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Recurrent spontaneous abortion (RSA) is defined as the loss of three or more consecutive pregnancies before 20 completed gestational weeks. The condition affects 0.5-1% of all women. In the majority of women with RSA, the cause remains unexplained after genetic, endocrine, immunological and anatomical investigations of the couple.

  3. 2. Reproductive aspects of the protein C system in women

    Författare :Margareta Wramsby; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Hypercoagulation; Factor V Leiden; APC resistance; Protein C inhibitor; Recurrent abortions; Menstrual cycle; Pregnancy; Controlled ovarian hyperstimulation.;

    Sammanfattning : Of great importance to the reproductive system in women are the activating and inhibiting factors which maintain haemostatic balance. These play a prominent role in the prevention of abnormal bleeding, at ovulation as well as during menstruation, pregnancy and delivery. The coagulation cascade is primarily down regulated by the protein C system. LÄS MER

  4. 3. Studies on the genetic basis of Pk, P and P1 blood group antigen expression

    Författare :Åsa Hellberg; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; serology; serologi; transplantation; Immunology; SNP; phenotype; erythrocyte; blood group; glycosyltransferase;

    Sammanfattning : The clinically important carbohydrate P/GLOB blood group systems and collection give rise to both common (P1, P2) and rare (p, P1k, P2k) blood group phenotypes. The associated antibodies are implicated in severe transfusion reactions and recurrent spontaneous abortions. LÄS MER

  5. 4. Female and male infertility in Nigeria : studies on the epidemiology of infertility in Nigeria with special reference to the role of genital tract infections and sexual and reproductive risk factors

    Författare :Friday Ebodaghe Okonofua; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Infertility; childlessness; genital infection; risk factors; serology; Nigeria;

    Sammanfattning : Background: Infertility is a major public health problem in Nigeria, contributing to inappropriate contraceptive behavior and poor sexual and reproductive health of women. To date, there is a paucity of scientific information relating to the factors that place men and women at risk of infertility in this population. LÄS MER

  7. 5. Studies of Thai blood group and platelet polymorphism. Implications for malaria susceptibility

    Författare :Philaiphon Jongruamklang; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thai; Blood group polymorphism; Human platelet antigens; Malaria susceptibility; Plasmodium falciparum;

    Sammanfattning : The objectives of the thesis were to seek a better understanding of polymorphic RBC surface molecules in the Thai, and to investigate the role of certain blood groups in malarial invasion. MALDI-TOF MS was employed in Study I as an efficient method for genotyping to establish the common blood group and platelet antigen genotypes of 396 blood donors. LÄS MER
