  1. 16. Molecular epidemiologic studies on helicobacter pylori infection and stomach cancer risk

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Medical Epidemiology and Biostatistics

    Författare :Zongli Zheng; Karolinska Institutet.; Karolinska Institutet.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori;

    Sammanfattning : Helicobacter pylori (H. pylori) infection increases stomach cancer risk. The aim of this thesis was to study genetic susceptibility from the host and to develop molecular methods for future characterization of bacterial virulence factors in longitudinal cohorts. LÄS MER

  2. 17. Effect of Cholecystokinin-B/Gastrin Receptor Antagonists on Rat Stomach ECL Cells

    Detta är en avhandling från Department of Pharmacology, Lund University

    Författare :Xi-Qin Ding; Lunds universitet.; Lund University.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; vävnadskultur; histokemi; cytokemi; Histologi; tissue culture; histochemistry; gastrin; cholecystokinin CCK receptors; ECL cells; CCK-B gastrin receptor antagonists; histidine decarboxylase HDC ; histamine; pancreastatin; chromogranin A CGA ; gastric acid secretion.; cytochemistry; Histology; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : The histamine- and pancreastatin- containing ECL cells in the acid-producing mucosa of the rat stomach operate under the control of circulating gastrin. The present work examines how cholecystokinin (CCK)-B/gastrin receptors regulate the activity of the ECL cells. LÄS MER

  3. 18. Helicobacter pylori infection and associated stomach pathology in the adult general population

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Neurobiology, Care Sciences and Society

    Författare :Tom Storskrubb; Karolinska Institutet.; Karolinska Institutet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The discovery of H. pylori infection has had a tremendous impact on the understanding and treatment of upper gastrointestinal diseases. It causes gastritis, sometimes developing to atrophy and intestinal metaplasia (IM), both considered as premalignant conditions and it is an important risk factor for peptic ulcer and non-cardia gastric cancer.

  4. 19. Helicobacter pylori associated effects on inflammatory radical formation and angiotensin II receptors in the stomach

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Neurobiology, Care Sciences and Society

    Författare :Anders Elfvin; Göteborgs universitet.; Gothenburg University.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; Mongolian gerbil; gastric adenocarcinoma; nitro-radical; iNOS; nitric oxide; nitrotyrosine; oxy-radical; myeloperoxidase; angiotensin II; AT1R; AT2R;

    Sammanfattning : Helicobacter pylori infection of the stomach always results in mucosal inflammation and a marked systemic immune response. Despite the profound host defence reactions the bacterium avoids elimination and persists in the mucosa. This results in chronic inflammation and an increased risk for peptic ulcers and adenocarcinoma. LÄS MER

  5. 20. Differential maturation of Na+, K+ -ATPase in the rat : Transcriptional regulation by glucocorticoids

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Zheng-Ming Wang; Karolinska Institutet.; Karolinska Institutet.; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glucocorticoids; ontogeny; Na ; K -ATPase; H ; K -ATPase; iontransporter; kidney; lung; heart; stomach; colon.;

    Sammanfattning : Na+,K+-ATPase is a ubiquitous transmembrane enzyme that creates theelectrochemical gradient across the cell membrane. Na+,K+-ATPase activity is lowin many immature tissues. LÄS MER
