11. Oropharyngeal origin of markers in exhaled breath
Abstract : Normal NO formation in the human airways occurs primarily in the nasal airways, where it is catalyzed by inducible NO synthase (iNOS), and in the oropharyngeal tract, via as yet not fully defined pathways. This NO can be detected in exhaled breath and when inflammation is present in the airways, for example in asthma, the concentration of NO is increased. READ MORE

12. New Instrumentation for Forensic Applications : Automatic Fiber Detection and Breath Alcohol Measurements
Abstract : Two forensic instruments have been developed and evaluated with respect to basic characteristics. One instrument is used for automatic fiber detection and the other for breath alcohol measurement. READ MORE

13. Exhaled Breath Condensate in Obstructive Lung Diseases : A Methodological study
Abstract : Asthma and chronic obstructive pulmonary disease (COPD) are two common inflammatory airway diseases characterized by airway inflammation and mucus hypersecretion. Prediction of the outcome of these diseases may not be performed and the need for non-invasive diagnostic tools capable of identifying inflammation in asthma and COPD becomes therefore obvious.

14. Biokinetics and radiation dosimetry of 14C-labelled triolein, urea, glycocholic acid and xylose in man. Studies related to nuclear medicine “breath tests” using accelerator mass spectrometry
Abstract : 14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. READ MORE

15. Respiratory drive assessment : an evaluation of the breath-by-breath occlusion pressure method in man
Abstract : A simplified concept of respiratory drive is to consider it as the integrated "output" from the CNS to the respiratory "pump" muscles. This drive is a result of a complex central respiratory pattern generation, and can in abnormal situations, e.g. of pathological or pharmacological origin, be altered. READ MORE
