  1. 6. Phytoplankton defense mechanisms against grazing : the role of grazing infochemicals

    Författare :Veronica Lundgren; Edna Granéli; Takeshi Yasumoto; Aaron Barkoh; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Many phytoplankton species have evolved a variety of different defenses to decrease losses from grazing; morphological features, changes in life-history/behavior, and production of toxins. These defenses may be associated with costs. Therefore, some phytoplankton only express the defense when needed, i.e. LÄS MER

  3. 7. Genotypic and phenotypic characterization of Porphyromonas gingivalis in relation to virulence

    Författare :Takashi Yoshino; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Porphyromonas gingivalis; Phenotype; Genotype; Virulence; Periodontitis;

    Sammanfattning : The present thesis was designed to increase the knowledge on the role of pathogenic potential of Porphyromonas gingivalis as a putative periodontal pathogen. P. LÄS MER

  4. 8. Host responses and bacterial virulence factors in Neisseria infections

    Författare :Linda Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neisseria; CD46; LPS; antimicrobial peptide.;

    Sammanfattning : Neisseria meningitidis and Neisseria gonorrhoeae are human specific pathogens. N. meningitidis is a major cause of meningitis and sepsis, whilst N. gonorrhoeae causes many millions of cases of gonorrhea in the world every year. LÄS MER

  5. 9. Programming Blood Cell Fates. Insights from Direct Lineage Conversion and Development

    Författare :Sandra Capellera Garcia; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic development; Erythropoiesis; Megakaryopoiesis; Direct Lineage Conversion;

    Sammanfattning : Red blood cells (RBC) and platelets constitute the non-immune branch of the hematopoietic system and are responsible for the vital functions of transporting oxygen to the tissues and clotting blood vessel injuries, respectively. These cells are produced during embryonic development and throughout life through a process called hematopoiesis which is tightly regulated by extrinsic and intrinsic factors. LÄS MER

  7. 10. Effects of 5-fluorouracil on oral barrier functions

    Författare :Inger von Bültzingslöwen; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Many anticancer drugs, e.g. 5-fluorouracil (5-FU), may cause oral mucositis and ulcerations. These adverse reactions can be severe and debilitating to the patient, and adjustment of the cancer treatment may be necessary. LÄS MER
