1. 1. Cardiac hypertrophy : transcription patterns, hypertrophic progression and extracellular signalling

   Författare :Nina Gennebäck; Stellan Mörner; Anders Waldenström; Urban Hellman; Ali J Marian; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac hypertrophy; HCM; gene expression; OPLS-DA; multivariate dataanalysis; cardiomyocytes; exosomes; microvesicles; Medicine; medicin;

   Sammanfattning : Background: The aim of this thesis was to study transcription patterns and extracellular signalling of the hypertrophic heart to better understand the mechanisms initiating, controlling and maintaining cardiac hypertrophy.Cardiac hypertrophy is a risk factor for cardiovascular morbidity and mortality.

3. 2. S100B and Cardiac Surgery

   Författare :Henrik Bjursten; Thoraxkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; S100-B; S100B; S100beta; brain damage; cardiac surgery; CABG; renal function; autotransfusion; Cardiovascular system; serum marker; Kardiovaskulära systemet;

   Sammanfattning : The brain-derived protein S100B is a 21 Kda dimerand have been used as a serum marker for brain damage of different etiology. The feasability of protein S100B as serum marker for brain damage after cardiac surgery was studied in this thesis. One unexpected finding was made, which changed the basis for interpration of S100B levels. LÄS MER

4. 3. Aspects of regular long-term endurance exercise in adolescents, with focus on cardiac size and function, hormones, and the immune system

   Författare :Louise Rundqvist; Maria Faresjö; Peter Blomstrand; Katarina Steding-Ehrenborg; Jönköping University; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; endurance-trained; cardiac dimension; cardiac systolic function; cardiac diastolic function; growth hormone; immune response; echocardiography; biomarkers; cytokines; chemokines; insulin-like growth factor 1; type 1 diabetes-related autoantigen; proinsulin;

   Sammanfattning : The long-term effects of starting high-intensity training at younger ages are largely unknown. The present studies focused on adolescents who had performed regular endurance exercise for several years at an elite level and compared those subjects with a control group of adolescents of similar age and sex who had not engaged in regular exercise.

5. 4. Acute Myocardial Infarction: The Relationship between Duration of Ischaemia and Infarct Size in Humans - Assessment by MRI and SPECT

   Författare :Erik Hedström; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Fysiologi; Physiology; humans; cardiac troponin T; creatine kinase isoenzyme MB; delayed contrast-enhanced magnetic resonance imaging; single photon emission computed tomography; myocardial perfusion; myocardial infarct size; myocardium at risk; duration of ischaemia; Kardiovaskulära systemet;

   Sammanfattning : The effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. LÄS MER

7. 5. Lipid Micro Emboli in Cardiac Surgery

   Författare :Atli Eyjolfsson; Thoraxkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : This thesis is based on five studies. It includes the characterization of lipid micro emboli in shed mediastinal blood during cardiac surgery. The reuse of blood directly by cardiotomy suction is a common practice in order to reduce the need of blood transfusions. LÄS MER
