  2. 1. Gastrointestinal mucosal protective mechanisms : Mudolatory effects of Heliobacter pyroli on the gastric mucus gel barrier and mucosal blood flow in vivo

    Author : Christer Atuma; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mucus gel layer; mucosal blood flow; mucus thickness; chronic infection; rat; platelet activating factor; mast cell; nitric oxide; nitric oxide synthase; ketotifen; intra-vital microscopy; microelectrode; laser-Doppler flowmetry; L-NNA; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The gastrointestinal mucus gel layer and blood flow are two important mechanisms for protection at the pre-epithelial and sub-epithelial levels, respectively. Helicobacter pylori might circumvent these mechanisms and elicit a chronic inflammatory response with consequent ulcers in the stomach and duodenum. READ MORE

  4. 2. Helicobacter pylori and Gastric Protection Mechanisms : An in vivo Study in Mice and Rats

    Author : Johanna Henriksnäs; Lena Holm; Lars Engstrand; Erik Persson; Lars Fändriks; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; mucus gel layer; mucosal blood flow; mucus thickness; intra-vital microscopy; laser-Doppler flowmetry; pH-sensitive microelectrode; nitric oxide; Helicobacter pylori; bicarbonate secretion; mouse model; Fysiologi; Physiology; Fysiologi;

    Abstract : The stomach is frequently exposed to hazardous agents and to resist this harsh environment, several protective mechanisms exist. Of special interest is the gastric pathogen Helicobacter pylori which causes gastritis, ulcers and cancer but the mechanism leading to these diseases are still unclear. However it is very likely that H. READ MORE

  5. 3. Nitrate, Nitrite and Nitric Oxide in Gastric Mucosal Defense

    Author : Joel Petersson; Lena Holm; Jon Lundberg; Mia Phillipson; Matthew Grisham; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dietary nitrate; mucus gel layer; mucosal blood flow; mucus thickness; laser-Doppler flowmetry; mucosal damage; intra-vital microscopy; mucosal permeability; Physiology; Fysiologi;

    Abstract : The human stomach normally contains high levels of bioactive nitric oxide (NO). This NO derives from salivary nitrate (NO3-) that is converted to nitrite (NO2-) by oral bacteria and thereafter non-enzymatically reduced in the acidic gastric lumen to NO. READ MORE

  6. 4. Long-term cardiovascular follow-up after preterm birth

    Author : Anna-Karin Edstedt Bonamy; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cardiovascular disease is a leading cause of morbidity and mortality worldwide. A large number of studies show that the risk of cardiovascular disease is increased in people born with low birth weight. READ MORE
