  1. 1. Aerobic fitness and healthy brain aging : cognition, brain structure, and dopamine

    Författare :Lars Jonasson; Carl-Johan Boraxbekk; Katrine Riklund; Emrah Düzel; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerobic exercise; VO2; working memory; executive function; freesurfer; striatum; dopamine; D2-receptors; [11C]raclopride;

    Sammanfattning : Background: Performing aerobic exercise and maintaining high levels of aerobic fitness may have positive effects on both brain structure and function in older adults. Despite decades of research however, there is still a rather poor understanding of the neurocognitive mechanisms explaining the positive effects of aerobic exercise on cognition. LÄS MER

  4. 3. The effect of wood properties on oxidative isolation of cellulose nanofibrils and characterization of networks

    Författare :Simon Jonasson; Kristiina Oksman; Lars Wågberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; wood; TEMPO-oxidation; nanofibril network; lignin; tension wood; transgenic tree; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Wood is a natural resource that has been an integral part of society for as long as humans have been on Earth. From serving as fuel for fire and construction material the applications of wood has been developed in modern times and only surged as a consequence of societal strive for sustainability and usage of green resources.

  5. 4. Signs of inflammation in different types of heart valve disease : The VOCIN study

    Författare :Lars Wallby; Lena Jonasson; Mats Broqvist; Mårten Rosenqvist; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart valve dysfunction; heart valve disease; VOCIN study group; aortic valves; Gross valvular pathology; Cariology; Cariologi;

    Sammanfattning : Heart valve dysfunction is a relatively common condition in the population, whereas significant heart valve disease is more unusual. The cause of different types of heart valve disease depends on which valve is concerned. Rheumatic heart valve disease, has for a long time been considered to constitute a post-inflammatory condition. LÄS MER

  7. 5. Low-Density Lipoprotein Oxidation and Renal Dysfunction : New Markers of Poor Prognosis in Patients with Unstable Coronary Artery Disease
