1. 16. Regional Lung Mechanics and Influence of an Active Diaphragm in Experimental Lung Injury

   Författare :Mariangela Pellegrini; Anders Sune Larsson; Göran Hedenstierna; Michael Quintel; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute respiratory distress syndrome; artificial respiration; diaphragm; pulmonary atelectasis; lung imaging; respiratory system; animal model; Fysiologi; Physiology; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Sammanfattning : Despite being an essential life-support strategy in severe respiratory failure, mechanical ventilation can, if not optimally set and monitored, lead to injury of the lung parenchyma and diaphragm. These conditions are called ventilator-induced lung injury and ventilator-induced diaphragmatic dysfunction (VIDD), respectively. LÄS MER

3. 17. Fractional moving blood volume in fetal organs estimated using power Doppler ultrasound

   Författare :Edgar Hernandez-Andrade; Lund Obstetrik och gynekologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; fetal adrenal gland; fetal lung; radionuclear microspheres; fetal lamb; perfusion; fetus; Power Doppler ultrasound; fractional moving blood volume;

   Sammanfattning : Power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. The aim of the present study was to develop a standardized method for quantification of the PDU signals recorded from a specific region of interest (ROI) within fetal organs. LÄS MER

4. 18. Lung growth and lung hypoplasia in congenital diaphragmatic hernia

   Författare :Carmen Mesas Burgos; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Pulmonary hypoplasia and persistent pulmonary hypertension are the main causes of mortality and morbidity in newborns with congenital diaphragmatic hernia (CDH). Prenatal tracheal occlusion or ligation (TL) is known to accelerate lung growth, but the mechanism of this is poorly understood. LÄS MER

5. 19. Angiogenesis Related Markers In Non-Small Cell Lung Cancer

   Författare :Daniel Brattström; Ola Brodin; Gunnar Wagenius; Torgny Rasmusen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Lung cancer; NSCLC; Therapy; Angiogenesis; VEGF; bFGF; Microvessel density; Survival; Onkologi; Oncology; Onkologi;

   Sammanfattning : This thesis investigated the predictive and the prognostic powers of angiogenesis related markers in both operable and inoperable non-small cell lung cancer (NSCLC) patients.In the first and second study, we investigated the serological fractions of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in 2 cohorts of patients with either operable or inoperable NSCLC.

7. 20. From Air to Aria. Relevance of Respiratory Behaviour to Voice Function in Classical Western Vocal Art

   Författare :Monica Thomasson; KTH; []
   Nyckelord :Abdominal wall; breathing; consistency; inhalation; lung volume; respiratory behaviour; phonation; rib cage; singers; singing; subglottal pressure; tracheal pull; vertical laryngeal position; voice source.;

   Sammanfattning : While previous studies of opera singers’respiratorybehaviour have focused on kinematic or dynamic aspects mainly,this thesis attempts to adopt a broader perspective. Not onlylung volumes, rib cage and abdominal wall kinematics areconsidered, but also the effects of lung volumes and respiratorybehaviour on phonation characteristics. LÄS MER
