  1. 1. Exploring Intestinal Ischemia An experimental study

    Detta är en avhandling från Umeå : Kirurgisk och perioperativ vetenskap

    Författare :Rolf Fröjse; Umeå universitet.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; gastrointestinal tonometry; continuous; pig; pHi; intestinal ischemia; intestinal vascular bed; lactate; tissue oxygen tension; microdialysis; dopexamine; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; Surgery; kirurgi;

    Sammanfattning : Background and aims: Unrecognized intestinal mucosal ischemia in severely ill patients may trigger development of multiple organ failure. Such ischemia can be evaluated by intraluminal tonometry reflecting mucosal PCO2 and intramucosal pH (pHi). LÄS MER

  2. 2. Intestinal Mucosa Reconstitution and Protection: Impact of Luminal Factors

    Detta är en avhandling från Department of Surgery, Clinical Sciences Lund, Lund University

    Författare :Yilei Mao; Lund University.; Lunds universitet.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Probiotics; Pectin; Oat; Methotrexate; Lactobacilli; Intestinal injury; Intestinal immunity; Intestinal barrier; Enterocolitis; Fiber; Radiation; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : The gastrointestinal mucosa is one of the most rapidly proliferating tissues in the body, and serves as a barrier to luminal bacteria and toxins. Enteral nutrition, luminal fiber and probiotics are of crucial importance for the integrity of this barrier. LÄS MER

  3. 3. Membrane transport and the human small intestine : Relation to mucosal protection, intestinal anaphylaxis and nitric oxide

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tina W. Knutson; Uppsala universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; albumin; bicarbonate secretion; carbonic anhydrase; dopamine; duodenum; histamine; humans; hyaluronan; intestinal anaphylaxis; intestinal obstruction; jejunum; lidocaine; LOC-I-GUT; nitecapone; nitric oxide; potential difference; prostaglandins; segmental intestinal perfusion; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; anestesiologi; Anaesthesiology;

    Sammanfattning : The tightly adherent monolayer of epithelial cells that line the luminal side of the intestine provides a dynamic and highly regulated barrier to the passive and active transport of ions, water and macromolecules. Cathecol-O-methyl transferase inhibition prevents tissue degradation of catecholaminesincluding dopamine and intracellular carbonic anhydrase activity is an important regulator of ion and water transport in the small intestine.

  4. 4. Intestinal preservation for transplantation: translational approaches

    Detta är en avhandling från Göteborgs universitet

    Författare :John M. Söfteland; Göteborgs universitet.; Gothenburg University.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intestinal transplantation; intestinal preservation; apoptosis; tight junction; luminal preservation;

    Sammanfattning : Background: Intestinal preservation injury (IPI) may result in various degrees of mucosal damage, which may later favor bacterial translocation, post-reperfusion syndrome, and upregulation of alloreactivity. Experimental evidence suggests that combining vascular perfusion and cold storage with luminal interventions using polyethylene glycol (PEG) solutions may mitigate the mucosal damage and extend the safe storage time.

  5. 5. Intestinal transport of levodopa : Implications for the therapy of Parkinson's disease

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Dag Nilsson; Uppsala universitet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Parkinson s disease; levodopa. duodenal Infusion; intestinal permeability; positron emission tomography; Neurovetenskap; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Neurology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Neurologi; Neurology; neurologi;

    Sammanfattning : Levodopa has been the basic treatment of patients with Parkinson's disease for the last 30 years. However, with time nearly all patients develop fluctuations in motor performance correlated to levodopa plasma concentrations. LÄS MER
