1. 6. Cardiopulmonary involvement in Puumala hantavirus infection

   Författare :Johan Rasmuson; Clas Ahlm; Anders Blomberg; Jamshid Pourazar; Gregory J. Mertz; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hemorrhagic fever with renal syndrome; hantavirus; echocardiography; respiratory function tests; computed tomography; bronchoalveolar lavage; biopsy; cytotoxic T cells; disease severity; Infectious Diseases; infektionssjukdomar;

   Sammanfattning : Puumala hantavirus (PUUV) causes hemorrhagic fever with renal syndrome in Europe. After inhalation of virus shed by bank voles, the virus systemically targets the vascular endothelium leading to vascular dysfunction and leakage. LÄS MER

3. 7. Lung function in micro- and in hypergravity

   Författare :Stéphanie Montmerle; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Lung physiology; human; spirometry; rebreathing; cardiogenic oscillations; phase IV; anti-G suit; stroke volume; weightlessness; closing volume; DLCO;

   Sammanfattning : The lung is extremely susceptible to gravity, even during short-term changes of the gravity vector, because it is a mixture of air and elastic tissue components. Yet, there is limited knowledge of the effects of gravity on the respiratory system. LÄS MER

4. 8. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling

   Författare :Ramin Ghorbani; Florian M. Schmidt; Anders Blomberg; Christoffer Boman; Staffan Schedin; Jonathan Beauchamp; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon monoxide CO ; pulmonary gas exchange; computational modeling; real-time breath gas analysis; single-exhalation profile; laser absorption spectroscopy; nonlinear least-squares fitting; breath sampling; baseline level; diurnal variation; healthy population; exposure study; fysik; Physics; Physiology; fysiologi;

   Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

5. 9. Ventilatory-perfusion relationships and respiratory drive in chronic obstructive pulmanory disease : with special reference to hypoxaemia, sleep quality and treatment with inhaled corticisteroid

   Författare :Karin Sandek; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : By measuring retention in blood and excretion in exhaled air of six infused inert gases using multiple inert gas technique (MIGET), it is possible to obtain detailed assessment of the ventilation-perfusion (VA/Q) relationships in patients with chronic obstructive pulmonary disease. Stable, non-bronchitic COPD patients show a substantial perfusion of hyper-ventilated lung regions. LÄS MER

7. 10. Lung function in smokers - Aspects on COPD diagnosis and associations to atherosclerosis and alcohol consumption

   Författare :Sophia Frantz; Malmö Klinisk fysiologi och nuklearmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lung function; smoking; COPD; IOS; atherosclerosis; alcohol consumption;

   Sammanfattning : Smoking is the most common and important risk factor for reduced lung function. Chronic Obstructive Pulmonary Disease (COPD) affects mainly smokers and is characterized by airflow obstruction, assessed using one of two major diagnostic spirometric criteria. LÄS MER
