  1. 1. Effects of palatable diets on appetite regulation, appetite peptides and neurogenesis

    Författare :Andreas Lindqvist; Aptitkontroll; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sekretion; Endokrinologi; diabetologi; Appetite regulation; Ghrelin; Obesity; Leptin; Endocrinology; diabetology; secreting systems;

    Sammanfattning : Obesity is increasing throughout the world at an epidemic rate, partly due to increased consumption of diets rich in fat and/or sugar. Ghrelin and leptin are hormones, originating from the periphery, involved in the regulation of food intake and of maintaining energy homeostasis. LÄS MER

  3. 2. Transglycosylation catalyzed by β-mannanases : Molecular aspects relevant for enzymatic synthesis

    Författare :Johan Morrill; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; β-mannanase; glycoside hydrolase; enzymology; kinetics; MALDI-TOF MS; HPLC; transglycosylation; alcoholysis; enzyme engineering; protein structure; enzymatic synthesis;

    Sammanfattning : β-Mannanases are a major type of enzyme involved in the hydrolysis and modification of β-mannans, a hemicellulose present in high amounts in e.g. softwoods such as spruce. The β-mannanases studied in this thesis belong to glycoside hydrolase (GH) families GH5 and GH26. LÄS MER

  4. 3. Age and gender differences in risk factor burden, myocardial dysfunction and cardiovascular events in relation to glucose metabolism

    Författare :Margrét Leosdottir; Internmedicin - epidemiologi; []
    Nyckelord :Age; cardiovascular disease; diabetes; echocardiography; gender; glucose; left ventricular function; Nt-proBNP; self-rated health;

    Sammanfattning : The risk of cardiovascular disease (CVD) and heart failure (HF) among individuals with diabetes is at least two times greater than in non-diabetic subjects. However, the excess risk of CVD in diabetic subjects seems to decrease with age. LÄS MER

  5. 4. Designing simultaneous saccharification and co-fermentation of lignocellulose for improved xylose conversion

    Författare :Kim Olofsson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; lignocellulose; simultaneous saccharification and co-fermentation; xylose fermentation;

    Sammanfattning : Fuel ethanol from lignocellulose is one sustainable alternative to the fossil fuels of today. All sugars in the material must be utilized in order to achieve high overall ethanol yields. Baker’s yeast, Saccharomyces cerevisiae, has been engineered to ferment the pentose sugar xylose from lignocellulose to ethanol. LÄS MER

  7. 5. Microbial biofilms on peritoneal dialysis catheters

    Författare :Maria Pihl; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peritoneal dialysis; Biofilm;

    Sammanfattning : Då njurarna slutar fungera produceras ingen urin, och avfallsprodukterna stannar kvar i blodet. Detta tillstånd kallas uremi (”urin i blodet”) och leder till döden om det inte behandlas. Det finns två artificiella sätt att rena blodet på, hemodialys och peritonealdialys. LÄS MER
