  2. 1. Creating Optical Activity: Total Spontaneous Resolution and Viedma Ripening

    Author : Per Martin Björemark; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical activity; absolute asymmetric synthesis; total spontaneous resolution; Viedma ripening; grinding; chirality; conglomerate; coordination compound; coordination polymer; single crystal X-ray diffraction; solvent free oxidation; nantioselective sulfide oxidation; solid state VCD;

    Abstract : The creation of optical activity has been considered as something impossible even though reports of such creation via total spontaneous resolution since the 1940´s have been published. More recently Viedma ripening have been developed that also produce enantiopure bulk product. Both methods are examples of absolute asymmetric synthesis i.e. READ MORE

  4. 2. Beyond the established risk factors of myocardial infarction : lifestyle factors and novel biomarkers

    Author : Patrik Wennberg; Jan-Håkan Jansson; Mai-Lis Hellénius; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lifestyle factors; physical activity; commuting activity; leisure time physical activity; occupational physical activity; snuff use; haemostatic markers; inflammatory markers; myocardial infarction; epidemiology; primary prevention.; Family medicine; Allmänmedicin; Family Medicine; allmänmedicin;

    Abstract : Age, male sex, hypertension, smoking, diabetes, dyslipidaemia, and obesity are considered as established risk factors for cardiovascular diseases. Several of these established cardiovascular risk factors are strongly influenced by lifestyle. READ MORE

  5. 3. Physical Activity and Cardiovascular Disease

    Author : Kasper Andersen; Johan Sundström; Claes Held; Frieder Braunschweig; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical activity; epidemiology; cohort study; heart failure; cardiovascular disease; arrhythmias; atrial fibrillation; bradyarrhythmias; sudden cardiac death; heart failure; stroke; ischemic heart disease; cardiovascular death; maximal exercise capacity; muscle strength; skeletal muscle morphology; Kardiologi; Cardiology; Epidemiology; Epidemiologi;

    Abstract : The aim was to investigate associations of fitness and types and levels of physical activity with subsequent risk of cardiovascular disease.Four large-scale longitudinal cohort studies were used. The exposures were different measures related to physical activity and the outcomes were obtained through linkage to the Swedish In-Patient Register. READ MORE

  6. 4. Beta-Glycosidases from Hyperthermophiles as Biocatalysts

    Author : Therese Hansson; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biochemical technology; Biokemisk teknik; Proteins; enzymology; Proteiner; enzymologi; Biotechnology; high temperatures; water activity; activity; selectivity; hexanol; hexyl-b-glycoside; galacto-oligosaccharides; lactose; hyperthermostable b-glycosidase; hydrolysis; optimisation; transglycosylation;

    Abstract : The thesis concerns glycosyl transfer with use of b-glycosidases, most of them from hyperthermophilic organisms. Both optimisation of the reaction conditions and protein engineering in terms of site-directed mutagenesis were used to improve b-glycosidase-catalysed reactions. READ MORE

  7. 5. Gait speed, physical activity, cognitive function and dementia : associations in cross-sectional and longitudinal studies and validity of a physical activity questionnaire in very old people

    Author : Jerry Öhlin; Annika Toots; Birgitta Olofsson; Håkan Littbrand; Stefan Söderberg; Anna Cristina Åberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait speed; cognitive function; dementia; physical activity; aged 80 and over; physiotherapy; fysioterapi;

    Abstract : Dementia and cognitive impairment are leading causes of disability in older people (≥ 65 years) and gait speed decline seem to be an early indicator of these conditions, sometimes preceding clinical symptoms. Dementia may be delayed or prevented with management of risk factors, such as low physical activity. READ MORE
