  1. 31. SODIUM/IODIDE SYMPORTER-NIS Abundant and Important in Gastric Mucosa

    Författare :Malin Josefsson; Neurogastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ussing chamber; MNNG; gastric iodide secretion; ouabain; gastric cancer; sodium perchlorate; gastric NIS; bile duct cancer; Sodium iodide symporter;

    Sammanfattning : ABSTRACT Background: Iodine is essential for development and growth as a constituent in thyroid hormones. Biological mechanisms for iodide uptake and concentration are very important, espe-cially as iodine is a relatively scarce element. LÄS MER

  2. 32. Systematics, phylogeography and multiple origins of morphs in two species complexes belonging to Cistaceae, Helianthemum oelandicum and H. nummularium

    Författare :Eman Soubani; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; introgression; parallel evolution; postglacial migration; genetic polymorphism; Pleistocene; morphometry; H. nummularium; Helianthemum oelandicum; cpDNA;

    Sammanfattning : The Helianthemum oelandicum complex shows considerable morphological variation across its geographic distribution in Europe and western Asia. By combining four primer pairs and four restriction enzymes I identified nine cpDNA haplotypes with distinct geographical distributions. LÄS MER

  3. 33. The threat from non indigenous species - ecosystem vulnerability, global distribution and co-occurrence with other major threats

    Författare :Helena Berglund; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; threats; distribution range; isolation; endemism; invasions; invaders; vulnerability; non indigenous species; rarity; threatened species;

    Sammanfattning : We live in a globalised world where people and goods travel large distances. Various species are brought along on these journeys, intentionally or as hitchhikers. Some of these species establish populations in regions to which they could not have spread without human assistance, and where they are considered to be non indigenous species (NIS). LÄS MER

  4. 34. The significance of urokinase-type plasminogen activator (u-PA) in tumour growth and Linomide-induced upregulation of u-PA's endogenous inhibitor PAI-2

    Författare :Anita Billström; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; roquinimex; Linomide; cancer; prostate cancer; PAI-2; plasmin; Plasminogen activators; u-PA; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : The progressive process of tumour invasion and generation of metastases is the primary cause of death for most patients with cancer. Some of the regulatory components of this progressive process are adhesion, migration, and proteolysis. LÄS MER

  5. 35. Genetic Characterization of Bone and Soft Tissue Tumors

    Författare :Anna Dahlen; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical genetics; Klinisk genetik; cytogenetik; Genetik; cytogenetics; mesenchymal tumor; pericytoma; Genetics; chondroma; lipoma;

    Sammanfattning : Bone and soft tissue tumors (BSTT) constitute a heterogeneous group of neoplasms of mesenchymal and neuroectodermal origin. Although many BSTT are rare, it has become clear that BSTT are characterized by recurrent acquired chromosomal aberrations, and the general aim of this thesis have been to apply molecular genetic and molecular cytogenetic techniques to further characterize recurrent breakpoints and deletions, and to search for candidate target genes.
