2. 21. Health effects of air pollution in Iceland : respiratory health in volcanic environments

   Author : Hanne Krage Carlsen; Anna Oudin; Thorarinn Gislason; Kadri Meister; Bertil Forsberg; Gunilla Wieslander; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory health; air pollution; volcanic ash; epidemiology; hydrogen sulfide.; Epidemiology; epidemiologi; folkhälsa; Public health;

   Abstract : Air pollution has adverse effects on human health. The respiratory system is the most exposed and short-term changes in air pollution levels have been associated with worsening of asthma symptoms and increased rates of heart attacks and stroke. Air pollution in cities due to traffic is the major concern, as many people are exposed. READ MORE

4. 22. Mucins in normal and diseased airways

   Author : Hans Hovenberg; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory system; Submucosal glands; Goblet cells; Organ culture; Respiratory tract; Mucins; Mucus glycoproteins; Andningsorganen;

   Abstract : Mucus glycoproteins (mucins) are the principal constituents of respiratory secretions in health and disease. The increased 'acidity' of mucin producing cells in the bronchitic airways is not reflected in a change of negative charge of bronchitic mucins. READ MORE

5. 23. Mechanistic Insights in the Biogenesis and Function of the Respiratory Chain

   Author : Hannah Dawitz; Martin Ott; Cristina Ugalde; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; respiratory chain; bc1 complex; cytochrome c oxidase; Cbp3; Rcf1; Rcf2; respiratory supercomplexes; biogenesis; mitochondria; Saccharomyces cerevisiae; Biochemistry; biokemi;

   Abstract : Mitochondria fulfill a plethora of functions, including harboring metabolic pathways and converting energy stored in metabolites into ATP, the common energy source of the cell. This last function is performed by the oxidative phosphorylation system, consisting of the respiratory chain and the ATP synthase. READ MORE

6. 24. Studies on nitric oxide in the respiratory system

   Author : Ulla Schedin; Karolinska Institutet; Karolinska Institutet; []
   Keywords : nitric oxide; endogenous; respiratory system; neonate; prematureinfant; animal; primate; elephant; chemiluminescence; electrochemical; nitrogen dioxide; trachea; nose; ;

   Abstract : Nitric oxide (NO) is formed in biological tissues and has regulatory functions in many organ systems. Endogenous NO has been found in exhaled air and NO is considered to have effects on the pulmonary circulation and bronchial tone, and to be one of the mediators for the circulatory adaptation at birth.
