6. Endocrine Disruption in Amphibians : Developmental Effects of Ethynylestradiol and Clotrimazole on the Reproductive System
Sammanfattning : Amphibian populations are declining world-wide and one of the suggested reasons is environmental pollutants. Studies of long-term effects on the reproductive system in frogs following larval exposure to environmental pollutants are scarce. It is therefore important to develop methods to study developmental reproductive toxicity in amphibians. LÄS MER
7. 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
8. Role of Islet Endothelial Cells in β-cell Function and Growth
Sammanfattning : The pancreatic islets are collections of endocrine cells, dispersed throughout the pancreas. In adult islets, endocrine cells are closely associated with capillary endothelial cells and receive a high blood perfusion. Transplanted pancreatic islets, on the other hand, have a vascular disturbance, manifested as decreased blood vessel density. LÄS MER
9. Nitric Oxide Exchange in Central and Peripheral Airways : Determinants in Health and Respiratory Disease
Sammanfattning : Background: Exhaled nitric oxide (NO) is a marker of eosinophilic steroid-sensitive inflammation in the airways of patients with respiratory disease. Moreover, information about the localization of inflammation in the respiratory tree is obtained by estimates of bronchial and alveolar contributions to exhaled NO. LÄS MER
10. Nitrate, Nitrite and Nitric Oxide in Gastric Mucosal Defense
Sammanfattning : 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. LÄS MER
