  1. 6. Atrial function and loading conditions in athletes

    Författare :Flavio D'Ascenzi; Michael Henein; Sergio Mondillo; Roxy Senior; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; athlete s heart; training; exercise; speckle-tracking echocardiography; atrial strain; atrial deformation; Cardiology; kardiologi;

    Sammanfattning : Intensive training is associated with hemodynamic changes that typically induce an enlargement of cardiac chamber. Despite LA dilatation in athletes has been interpreted as a benign adaptation, little evidence is available. LÄS MER

  3. 7. Structural concrete elements subjected to air blast loading

    Författare :Johan Magnusson; Anders Ansell; Bengt Vretblad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Sammanfattning : In the design of structures to resist the effects of air blast loading or other severe dynamic loads it is vital to have large energy absorbing capabilities, and structural elements with large plastic deformation capacities are therefore desirable. Structures need to be designed for ductile response in order to prevent partial or total collapse due to locally failed elements. LÄS MER

  4. 8. Hyaluronan and Renal Fluid Handling : Studies during Normal and Pathological Conditions of Renal Function

    Författare :Viktoria Göransson; Mats Rundgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; CD44; gerbils; hyaluronan; ischemia-reperfusion; kidney; osmolality; oxygen tension; rat; renomedullary interstitial cells; water; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Sammanfattning : The kidney is the major organ responsible for the regulation of the composition and volume of the body fluids, which is essential for homeostasis. The glycosaminoglycan hyaluronan (HA), with extreme water-binding capacity, is present in the interstitium of the kidney with a heterogenous distribution. LÄS MER

  5. 9. Traumatic high-load injuries in the adolescent spine. Clinical, radiological and experimental studies

    Författare :Adad Baranto; Göteborgs universitet; []
    Nyckelord :Adolescence; athletes; spinal loading; back pain; disc degeneration; growth zone; intervertebral disc; MRI; nucleus pulposus; porcine spine; radiography; spine; vertebral endplate;

    Sammanfattning : Background: Disc degeneration and other radiological abnormalities are highly frequent among young athletes in sports with great demands on the back. It has also been reported that athletes with these abnormalities have more back pain than other athletes and non-athletes. LÄS MER

  7. 10. Hemodynamic and cardiometabolic studies in patients with distributive circulatory dysfunctions : with special reference to the effects of the beta-1-adrenoreceptor agonist prenalterol

    Författare :Sebastian Reiz; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic aneurysm surgery; gram negative septic shock; hemodynamics; myocardial metabolism; thermodilution; thoracic epidural block; volume loading; prenalterol;

    Sammanfattning : A total of 49 patients were studied, using invasive hemodynamic techniques with systemic arterial, pulmonary artery and right atrial pressure recordings together with thermodilution cardiac output determinations. Sixteen of the patients were also subjected to cardiometabolic studies, using measurement of coronary sinus blood flow by the continuous thermodilution technique and analyses of oxygen content and lactate concentration in the systemic and coronary circulation.
