1. 1. Aspects on luminal nitric oxide in relation to oesophageal acid exposure and mucosal integrity

   Författare :Mogens Bove; Göteborgs universitet; []
   Nyckelord :nitric oxide; nitric oxide synthase; acid; gastro-esophageal reflux disease; membrane potentials; saliva; nitrate; blood flow; ferret; histopathology;

   Sammanfattning : Nitric oxide (NO) exerts important neuromuscular control of the oesophagus, but little is known about the sources and effects of the NO present in the distal oesophageal lumen. These questions were presently addressed in both human and animal experiments. LÄS MER

4. 3. Inhaled Nitric Oxide Therapy : Non-response and Rebound Response

   Författare :Luni Chen; Eddie Weitzberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; nitric oxide inhalation; rebound response; non-response; endothelin-1; COX inhibitor; prostaglandin; ARDS; endotoxin; oleic acid; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : Therapeutic inhaled nitric oxide (INO) has proved beneficial in patients with pulmonary hypertension. However, around 30-40% of the patients are non-responders to this therapy, and a life-threatening rebound response may occur during attempts to withdraw INO. LÄS MER

5. 4. Crystallization of Metal Fluoride Hydrates from Mixed Acid Solutions

   Författare :Kerstin Forsberg; Åke Rasmuson; Alison Lewis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crystallization; crystal growth; b-FeF3.3H2O; iron fluoride trihydrate; CrF3.3H2O; pickling; pickle bath; hydrofluoric acid; nitric acid; stainless steel; Chemical engineering; Kemiteknik;

   Sammanfattning : In this work crystal growth and nucleation of b-FeF3×3H2O and crystallization of chromium (III), iron (III) and nickel (II) fluoride hydrates from mixed acid (1-3 mol/kg HNO3 and 1-6 mol/kg free HF) have been investigated. The solubility of b-FeF3×3H2O has been determined in solutions of different hydrofluoric acid (1-7mol/ kg) and nitric acid (0-7mol/ kg) concentrations at 30, 40 and 50°C. LÄS MER

7. 5. Helicobacter pylori interference with the L-arginine/NO pathway in the upper gut

   Författare :Charlotte Von Bothmer; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acid; bicarbonate; duodenal ulcer; Helicobacter pylori; host defence; mucosa; nitric oxide; nitric oxide synthase;

   Sammanfattning : Helicobacter pylori causes chronic gastritis and sometimes peptic ulcers but the pathogenesis is not fully understood. H. pylori-infected individuals with duodenal ulcer have an impaired duodenal mucosal bicarbonate secretion (DMBS) in response to acid. NO is an important signalling molecule in the body. LÄS MER
