    Sammanfattning : Glycosidases hydrolyse the glycosidic bond in carbohydrates. Structural studies of three glycosidases with different substrate specificities are presented in this work.Dextranase catalyzes the hydrolysis of α-1,6-glycosidic linkage in dextran polymers. LÄS MER

  3. 22. Plant and microbial xyloglucanases: Function, Structure and Phylogeny

    Författare :Jens Eklöf; Harry Brumer; Harry Gilbert; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; xyloglucan; xyloglucanases; XTH; XET; XEH; endoglucanases; EG16; Molecular biology; Molekylärbiologi;

    Sammanfattning : In this thesis, enzymes acting on the primary cell wall hemicellulose xyloglucan are studied.  Xyloglucans are ubiquitous in land plants which make them an important polysaccharide to utilise for microbes and a potentially interesting raw material for various industries.

  4. 23. Probing Interactions between Bio-Fibre Components

    Författare :Niklas Nordgren; Mark Rutland; Harry Brumer; Vincent Bulone; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AFM; QCM-D; cellulose; xyloglucan; surface forces; friction; colloidal probe; nanotribology; biomimetic; enzymatic; polysaccharide; self assembly; grafting; thiol; spring constant; calibration; photodetector calibration.; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : I den här avhandlingen har atomkrafts mikroskopi (AFM) och kvartskristall mikrovåg med dissipation (QCM-D) används för att undersöka interaktioner i bio-fiber modell system av cellulosa och xyloglukan (XG); en naturligt förekommande polysackarid viktig för tillväxt av träd och andra växter. Dessutom har det avgörande momentet av friktionskrafts-kalibrering studerats för att erhålla noggranna och kvantitativa resultat med kolloidal prob AFM. LÄS MER

  5. 24. Inguinal hernia surgery : aspects on chronic pain and contralateral repair

    Författare :Anders Olsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Inguinal hernia is common, and the only permanent treatment is surgical repair. Approximately 16,000 hernia repairs are performed annually in Sweden. Optimized surgical technique including mesh prosthesis decreases the prevalence of recurrences and the main outcome measurement is today chronic postoperative inguinal pain (CPIP). LÄS MER

  7. 25. Haemorrhoids : Aspects of Symptoms and Results after Surgery

    Författare :Helgi Örn Jóhannsson; Wilhelm Graf; Lars Påhlman; Olof Hallbök; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Haemorrhoids; Haemorrhoidectomy; Faecal incontinence; Irritable Bowel Syndrome; Bowel symptoms; Sphincter pressure; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : One hundred haemorrhoid patients were compared with 300 matched control persons. Haemorrhoid symptoms and bowel symptoms were studied. Most common symptom of the patients was bleeding (44%), followed by prolapse (24%), hygiene problem (14%), pain (12%) and itching (5%). LÄS MER
