2. 1. Heart Regeneration : Lessons from the Red Spotted Newt

   Author : Nevin Witman; Jamie Morrison; Thomas Braun; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heart; Regeneration; Newt; microRNAs; RNA editing; Molecular Biology; molekylärbiologi;

   Abstract : Unlike mammals, adult salamanders possess an intrinsic ability to regenerate complex organs and tissue types, making them an exciting and useful model to study tissue regeneration. The aims of this thesis are two fold, (1) to develop and characterize a reproducible cardiac regeneration model system in the newt, and (2) to decipher the cellular and molecular underpinnings involved in regeneration.

4. 2. Heart preservation

   Author : Guangqi Qin; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : In clinical transplantation today, the donor heart is preserved with cold ischemic storage that gives safe preservation for 4 hours. Non-ischemic perfusion preservation is able to preserve the donor heart for 24 hours in pre-clinical studies. The aim of this thesis is to investigate: 1. READ MORE

5. 3. Echocardiographic measurements of the heart : with focus on the right ventricle

   Author : Karin Loiske; Kent Emilsson; Allan Sirsjö; Jan Engvall; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; heart; right ventricle; right ventricular outflow tract 1; isovolumetric relaxation time; maximal early diastolic relaxation velocity; takotsubo cardiomyopathy; long-axis function; MEDICINE; MEDICIN; Clinical physiology; Klinisk fysiologi; Biomedicin; Biomedicine;

   Abstract : Echocardiography is a well established technique when evaluating the size and function of the heart. One of the most common ways to measure the size of the right ventricle (RV) is to measure the RV outflow tract 1(RVOT1). Several ways to measure RVOT1 are described in the literature. READ MORE

6. 4. Functional and morphological MR studies in congenital cardiovascular malformations

   Author : Catarina Holmqvist; Lund Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; Contrast-enhanced MR angiography.; Coarctation; Intra-cardiac shunts; Conduits; Tetralogy of Fallot; Function; Flow; MR velocity mapping; Infants; Children; Magnetic Resonance Imaging; Angiocardiography; Heart; Congenital heart defects; medical instrumentation; tomography; radiology; Clinical physics;

   Abstract : The aim of this study was to evaluate new MR techniques permitting qualitative and quantitative analysis of cardiac function and measurement of velocity and flow, and later on contrast-enhanced MR angiography, techniques largely unexplored in children with CHD. Infants with tetralogy of Fallot and pulmonary atresia with ventricular septal defect were examined pre-operatively. READ MORE

7. 5. Being physically active as an adult with congenital heart disease

   Author : Annika Bay; Bengt Johansson; Kristina Lämås; Malin Berghammer; Camilla Sandberg; Anna Strömberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult congenital heart disease; congenital heart disease; heart defect; physical activity; exercise self-efficacy; muscle function; quality of life; nursing; interviews; content analysis; prevention; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

   Abstract : Background: Due to advances in medical and surgical care adults with congenital heart disease (CHD) is a growing and aging population, that now outnumbers the children with CHD. In general, adults with CHD have reduced aerobic exercise capacity and nearly half of the patients do not reach current recommendations on physical activity. READ MORE
