1. 6. Patient-Specific Finite Element Modeling of the Blood Flow in the Left Ventricle of a Human Heart

   Författare :Jeannette Hiromi Spühler; Johan Hoffman; Johan Jansson; Mariano Vazquez; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Finite element method; Arbitrary Lagrangian-Eulerian method; Fluid-Structure interaction; Contact model; parallel algorithm; blood flow; left ventricle; aortic valves; patient-specific heart model;

   Sammanfattning : Heart disease is the leading cause of death in the world. Therefore, numerous studies are undertaken to identify indicators which can be applied to discover cardiac dysfunctions at an early age. LÄS MER

3. 7. Cerebellar development and very preterm birth interactions with neonatal events

   Författare :Kristbjorg Sveinsdottir; Lund Pediatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : AbstractThe cerebellum is an important part of the brain and in very preterm infants the cerebellum is smaller at term equivalent age compared to that of infants born at term.Hypothesis and aims: The general hypothesis is that preterm birth per se causes cerebellar underdevelopment and that certain events following preterm birth, either complications or treatments, can aggravate the underdevelopment.

4. 8. Electromechanical effects and optimization modalities of cardiac resynchronization therapy

   Författare :Cinzia Valzania; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cardiac resynchronization therapy; coronary blood flow; dyssynchrony; echocardiography; exercise; heart failure; hemodynamics; intracardiac electrogram; intracardiac impedance; optimization;

   Sammanfattning : Background and aims: Heart failure is a major health care problem, with high morbidity and mortality rates. In recent years, cardiac resynchronization therapy (CRT) has become an established additive treatment for patients with advanced heart failure, left ventricular (LV) dysfunction, and wide QRS complex.

5. 9. Neural stem cells and their contribution to neurogenesis in the adult mammalian brain

   Författare :Stefan Momma; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : For a long time it was believed that neurogenesis in the mammalian central nervous system was restricted to the embryonic and early postnatal period. Almost four decades ago Altman and colleagues challenged this notion, but it took more than thirty years before new studies with refined methods convincingly demonstrated neurogenesis in the adult mammalian brain, including the adult monkey and human brain.

7. 10. Long-term follow-up of very low birthweight children : A prospective study from the southeast region of Sweden

   Författare :Per-Olof Gäddlin; Ingemar Leijon; Orvar Finnström; Torstein Vik; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Very low birthweight infants; Follow-up studies; Adolescence; Gender; Neonatal risk factors; Magnetic Resonance Imaging; Cognitive function; School performance; Health; Quality of Life; Paediatric medicine; Pediatrisk medicin;

   Sammanfattning : Background: The survival rates for very low birthweight (VLBW; birthweight ≤1500 g) children are increasing, but they run a greater risk than controls of developing neurosensory disabilities and other functional problems during childhood. However, there is a great need for more knowledge regarding long-term outcome to adulthood in VLBW subjects. LÄS MER
