  2. 6. Integrating Biosensors for Air Monitoring and Breath-Based Diagnostics

    Author : Niklas Sandström; Wouter van der Wijngaart; Fredrik Nikolajeff; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The air we breathe is the concern of all of us but nevertheless we only know very little about airborne particles, and especially which biological microorganisms they contain. Today, we live in densely populated societies with a growing number of people, making us particularly vulnerable to air transmission of pathogens. READ MORE

  4. 7. Source-specific volatile organic compounds in human breath, wood smoke and biogas

    Author : Susan Björkqvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VOC; cymene; furans; methane; SBS; isoprene; limonene;

    Abstract : Volatile biogenic compounds are often overlooked in air quality studies. This work deals with the analysis of specific organic compounds of biogenic origin and with their sources. General aspects of indoor air chemistry and measurements of volatile organic compounds in indoor air are also discussed. READ MORE

  5. 8. Analysis of Endogenous Particles in Exhaled Air

    Author : Ann-Charlotte Almstrand; Göteborgs universitet; []
    Keywords : exhaled particles; time-of-flight secondary ion mass spectrometry; OPLS; airway closure; exhaled breath condensate; glutathione;

    Abstract : Exhaled air contains non-volatile particulate material from the respiratory tract. The precise location in which exhaled particles are formed is unknown, and details on their chemical content are scarce. The aim of this work was to chemically characterize and to study the mechanisms of formation of endogenous particles in exhaled air. READ MORE

  6. 9. Non-invasive analysis of leukotrienes as biomarkers of airway inflammation : method development and clinical applications

    Author : Flora Gaber; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Airway inflammation; aspirin-intolerant asthma; biomarker; exhaled breath condensate; FENO; induced sputum; leukotrienes; 5-lipoxygenase; non-invasive analysis; saliva;

    Abstract : Asthma and chronic obstructive pulmonary disease (COPD) are two common diseases characterized by chronic airway inflammation, but the inflammation in asthma is different from the one in COPD. In addition, asthma is a heterogeneous disease presenting with many different phenotypes (e.g. READ MORE

  7. 10. MRI sequences for detection of acute pulmonary embolism

    Author : Roberto Vargas Paris; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In recent years a range of imaging techniques have emerged to help diagnose patients with suspected acute Pulmonary Embolism (PE). This is particularly useful for those who are contraindicated (renal failure or allergies) to the contrast media that is needed to perform Computed Tomography Pulmonary Angiography (CTPA), which would be the usual diagnostic tool of choice.
