  2. 2. Physical Training and Testing in Patients with Chronic Obstructive Pulmonary Disease (COPD)

    Author : Ragnheiður Harpa Arnardóttir; Gunnar Boman; Kjell Larsson; Margareta Emtner; Hans Hedenström; Sven Larsson; Uppsala universitet; []
    Keywords : Physical therapy; chronic obstructive pulmonary disease; pulmonary rehabilitation; physical training; endurance training; interval training; health-related quality of life; exercise testing; walking tests; physiotherapy; Sjukgymnastik;

    Abstract : The overall aims of the studies were to investigate the effects of different training modalities on exercise capacity and health-related quality of life (HRQoL) in patients with moderate or severe COPD and, further, to explore two of the physical tests used in pulmonary rehabilitation.In study I, the 12-minute walking distance (12MWD) did not increase on retesting in patients with exercise-induced hypoxemia (EIH) whereas 12MWD increased significantly on retesting in the non-EIH patients.

  3. 3. Purification, Stereoisomeric Analysis and Quantification of Biologically Active Compounds in Extracts from Pine Sawflies, African Butterflies and Orchid Bees

    Author : Joakim Bång; Erik Hedenström; Kristina Sjödin; Hans-Erik Högberg; Anna-Karin Borg-Karlsson; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Semiochemicals; sex pheromone; pine sawflies; Bicyclus; Euglossa; chiral separation; derivatisation; GC-­MS; Organic chemistry; Organisk kemi;

    Abstract : Stereochemistry plays an important role in nature because biologically important molecules such as amino acids, nucleotides and sugars, only exist in enantiomerically pure forms. Semiochemicals carry messages, between the same species (pheromones) and between different species (allelochemicals). READ MORE

  4. 4. Lung function in relation to exercise capacity in health and disease

    Author : Amir Farkhooy; Andrei Malinovschi; Christer Janson; Hans Hedenström; Harrpa Arnardottir; Ann Ekberg Jansson; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise capacity; Exercise test; Lung function; Spirometri; Diffusion capacity; COPD; Pulmonary hypertension; Clinical Physiology; Klinisk fysiologi;

    Abstract : Background: Exercise capacity (EC) is widely recognized as a strong and independent predictor of mortality and disease progression in various diseases, including cardiovascular and pulmonary diseases. Furthermore, it is generally accepted that exercise capacity in healthy individuals and in patients suffering from cardiovascular diseases is mainly limited by the maximum cardiac output. READ MORE

  5. 5. The Immune Response to One-Lung Ventilation : Clinical and Experimental Studies

    Author : Thomas Schilling; Göran Hedenstierna; Hans Hedenström; Thomas Hachenberg; Sven-Erik Ricksten; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; One-lung ventilation; open thoracic surgery; ventilation-induced lung injury; alveolar immune response; bronchoalveolar lavage; propofol; desflurane; cytokines; animal model; mRNA; RT-PCR; Medical laboratory science; Medicinsk laboratorievetenskap; anestesiologi; Anaesthesiology;

    Abstract : One-lung ventilation (OLV) as an established procedure during thoracic surgery may be injurious in terms of increased mechanical stress characterised by alveolar cell stretch and overdistension, increased cyclic tidal recruitment of alveolar units, compression of alveolar vessels and increased pulmonary vascular resistance. This may result in ventilation-induced lung injury with pro-inflammatory cytokine production, leukocyte recruitment and neutrophil-dependent tissue destruction. READ MORE
