1. Helicobacter pylori and Gastric Protection Mechanisms : An in vivo Study in Mice and Rats
Sammanfattning : 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. LÄS MER
2. Gastric gland luminal pressure and mucosal protection : An in vivo study in the anesthetized rat
Sammanfattning : The driving force for creation of channels in gastric mucus, for acid and pepsin transport, ismost probably the hydrostatic pressure generated within the gastric gland lumen. The aim ofthis study was to investigate the origin and regulation of the glandular pressure. LÄS MER
3. Short and long-term effects of exposure to low dose and low dose rate of gamma radiation : using in vitro and in vivo models
Sammanfattning : Assessment of human health risks from exposure to ionizing radiation (IR) is mainly based on the extrapolation of results from epidemiological studies on populations exposed to relatively high doses and often at high dose rates (HDR). Risk estimates after exposure to low doses and in particular at low dose rates (LDR) remain controversial due to a lack of epidemiological evidence. LÄS MER
4. Acid transport through gastric mucus : A study in vivo in rats and mice
Sammanfattning : The gastric mucosa is frequently exposed to endogenously secreted hydrochloric acid of high acidity. Gastric mucosal defense mechanisms are arranged at different levels of the gastric mucosa and must work in unison to maintain its integrity. LÄS MER
5. Toll-like receptors in airway inflammation in vitro and in vivo
Sammanfattning : During evolution a variety of solutions has been developed by different living organisms in order to protect itself from invading potential pathogens and particles. Protection of the host is essential for its survival and involves efficient recognition and elimination of potential pathogens. LÄS MER
