    Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER

  2. 17. Pharmacokinetics of the enantiomers of thalidomide

    Författare :Tommy Eriksson; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein binding; blood distribution; stereoselective pharamacokinetics; pharmacokinetic modelling; oral administration; intravenous administration; chiral inversion; stereospecific assay; HPLC; Thalidomide; hydroxylated metabolites; enantiomers; in vitro kinetics; sedative effects; concentration-effect relationship.; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : Thalidomide has a chiral center and the racemate of (+)-(R) and (-)-(S)-thalidomide was introduced as a hypnotic/sedative drug in 1957. In 1961 it was withdrawn due to teratogenicity and neuropathy. There is a growing interest in thalidomide treatment of immunomodulatory diseases. LÄS MER

  3. 18. Regulation of inducible nitric oxide synthase - Consequences in experimental models of bladder disease

    Sammanfattning : Inducible nitric oxide synthase (iNOS) expression is associated with various pathophysiological conditions in the lower urinary tract. The aims of this thesis have been to investigate the regulation of iNOS in bladder smooth muscle cells and the consequences on neuromuscular regulation, cell growth and differentiation. LÄS MER

  4. 19. Tissue remodelling in pulmonary fibrosis linked to 5-HT2 receptor activation

    Författare :Anna Löfdahl; Lungbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Serotonin 5HT ; Serotonin class 2 receptor antagonist; Fibroblast; Pulmonary fibrosis; Extracellular matrix ECM ;

    Sammanfattning : After an injury, an immediate reparative response is triggered to replace the damaged tissue, however, in fibrosis, cells remain active despite wound resolution causing a steady build-up of fibrotic tissue. In pulmonary fibrosis,there is a constant regeneration and remodelling of lung tissue where the thin architecture of alveoli become thickened, hampering efficient diffusion of oxygen, as seen in diseases like idiopathic pulmonary fibrosis (IPF).

    Sammanfattning : It is frequently argued that cannabinoids exert part of their analgesic and anti-inflammatory effects via activation of the cannabinoid CB1 receptor located on TRPV1-expressing primary sensory nerve fibres in peripheral tissues. However, we find no evidence of CB1 receptor immunoreactivity on nerve fibres in rat or mouse hindpaw skin and mesenteric artery. LÄS MER
