2. 1. Exhaled markers of oxidative stress in the airways

   Author : Mona Lärstad; Göteborgs universitet; []
   Keywords : exhaled air; exhaled breath condensate; malondialdehyde; 3-nitrotyrosine; ethane; pentane; isoprene; oxidative stress; airways; inflammation;

   Abstract : Breath contains a number of different molecules, some of which may have potential use as markers for oxidative stress in the airways during chronic airway inflammation. The major objectives were to develop and validate methods for quantifying five potential exhaled markers of oxidative stress: malondialdehyde (MDA) and free 3-nitrotyrosine (3-NT) in exhaled breath condensate (EBC) and ethane, pentane and isoprene in exhaled air, and to test the applicability of the methods.

4. 2. Mass spectrometric investigation of protein nitration in inflammation and neurodegeneration

   Author : Henrik Ryberg; Göteborgs universitet; []
   Keywords : mass spectrometry; oxidative stress; nitrotyrosine; neurodegeneration; peroxynitrite; protein modification;

   Abstract : The nitration of tyrosine seems to be very common in human diseases and at least forty different diseases have been reported to be associated with an increased nitration of proteins. The nitration of proteins results in a modification of tyrosine, 3-nitrotyrosine (3-NT), which is stable. READ MORE

5. 3. Experimental Helicobacter pylori infection in an animal model

   Author : Yi-Qian Sun; Torkel Wadström; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Background: Helicobacter pylori is a microaerophilic Gram-negative bacterium colonizing the human stomach. The prevalence of this infection is between 20-90% depending on geographic location. Comprehensive studies have shown significant relationships between H. pylori infection and chronic gastritis, peptic ulcer and gastric carcinoma. READ MORE
