  1. 1. Selection of the principal cause of death : studies on the basis of mortality statistics for rheumatoid arthritis

    Author : B Ingemar B Lindahl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : rheumatoid arthritis;

    Abstract : The official statistics of Sweden for 1971-75 show a 2.7-fold increase in mortality for men and a 3.0-fold increase for women attributed to rheumatoid arthritis (RA) as the underlying cause of death. In order to investigate the basis of this observed increase, all death certificates for 1971 and 1975 with a diagnosis of RA (N=1224) were studied. READ MORE

  2. 2. On Causal Attribution

    Abstract : This dissertation treats of the problem of attributing the occurrence of an individual event or state to a single cause — a problem commonly understood either as a question of distinguishing the cause from the mere conditions or as a matter of singling out, from several causes, one cause, as the cause. The main purpose of the study is to clarify some basic concepts, and some criteria of ascertainment of the cause, that may be discerned in the literature on causal attribution. READ MORE

  3. 3. HDZip I Transcription Factors in Arabidopsis thaliana : Expression and Function in Relation to Environmental Stress Conditions

    Author : Anna S. B. Olsson; Peter Engström; Eva Söderman; Pieter B. F. Ouwerkerk; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; homeodomain leucine zipper; ABA; transcription factor; water deficit; Arabidopsis thaliana; Biologi; Biology; Biologi;

    Abstract : The homeodomain leucine zipper (HDZip) proteins constitute a plant-specific family of transcription factors, that based on sequence criteria have been grouped into four classes, HDZip I-IV. This thesis describes the phylogeny, function, expression patterns and regulation of the HDZip class I genes in the model species Arabidopsis thaliana. READ MORE

  4. 4. Standardization of Islet Isolation and Transplantation Variables

    Author : Andrew S Friberg; Olle Korsgren; Daniel Brandhorst; Paul R. V. Johnson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet isolation; standardization; enzyme; gradient separation; digital imaging analysis; DIA; transplantation outcome; islet transplantation; prediction; Medical technology; Medicinsk teknik; Medical Cell Biology; Medicinsk cellbiologi; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Currently, the transplantation of islets of Langerhans is a viable means to maintain control of blood sugar levels and reduce the risk of hypoglycemia in defined populations with brittle type I diabetes mellitus or those requiring pancreatectomy. However, the process of islet isolation is highly variable and not all isolations result in islet numbers or quality suitable for transplantation. READ MORE

  5. 5. Hepatitis B virus replication and integration

    Author : Simon B. Larsson; Göteborgs universitet; []

    Abstract : Chronic infection with hepatitis B virus (HBV) affects 240 million people worldwide and may cause liver disease including hepatocellular carcinoma (HCC). Initially patients have high levels of HBV DNA in their blood, no liver disease and express the e antigen (HBeAg). READ MORE
