6. Sucrose cleavage pathways in aspen wood
Sammanfattning : Cellulose is the main component of wood and one of the most important renewable raw materials. In several tree species including Populus species, carbon for cellulose biosynthesis is derived from the disaccharide sucrose. LÄS MER
7. Antioxidants in Andean food and meals
Sammanfattning : Abstract The constant need to improve health and to prevent disease in Bolivia, especially in the Andean region with its extreme environmental conditions (high altitude and lower temperatures), motivated us to extend studies of antioxidant sources in foods and plants, since antioxidants are believed to have major health benefits. Spectrophotometric methods, such as ABTS (2, 2’- azinobis-3-ethylbenzotiazoline-6-sulfonic acid) and FRAP (ferric reduction antioxidant power), were used to evaluate antioxidant activity. LÄS MER
8. Articular cartilage proteoglycan biosynthesis and sulfation
Sammanfattning : Glucosamine (GlcN) and glucosamine sulfate (GS) have been used to treat the patients with osteoarthritis(OA) as a disease-modifying agent. Previousin vitro studies have focused on the effects of GlcN or GSon cartilage metabolism, whereas in vivo studies have investigated their potential for the treatment of OA. LÄS MER
9. Physiological and clinical studies of calcium-regulating hormones calcitonin and parathyroid hormone-related protein
Sammanfattning : The present studies were performed to elucidate several physiological and clinical questions of calcitonin (CT) and parathyroid hormone-related protein (PTHrP) such as: a) Does age influence the basal and calcium-stimulated levels and circulating molecular forms of CT in healthy females? b) Are osteoporotic patients lacking circulating monomeric CT? c) How is salmon CT (sCT) absorbed and cleared during treatment of diseases? d) Is there any effect of acute physical activity on circulating CT, PTH, PTHrP and bone metabolic markers? e) Is there an absorbance of PTHrP in milk by the neonate? and f) Are there any interactions between CT and PTHrP? In addition, by use of time-resolved dissociation and enhancement lanthanide fluorometry, the effort was put to develop two-site immunofluorometric assays (IFMA) for sCT and PTHrP as well as a quantitative competitive PCR (QC-PCR) for measuring PTHrP mRNA and use these methods in some of the investigations. Heterogeneity of CT forms in serum was disclosed after immunoextraction, fast protein liquid chromatography (FPLC) and radioimmunoassay (RIA) in healthy females and osteoporotic patients. LÄS MER
10. Identification of candidate genes involved in Mercury Toxicokinetics and Mercury Induced Autoimmunity
Sammanfattning : BACKGROUND: Autoimmune diseases require the involvement and activation of immune cells and occur when the body builds up an immune response against its own tissues. This process takes place due to the inability to distinguish self-antigen from foreign antigen. Systemic autoimmunity represents an important cause of morbidity and mortality in humans. LÄS MER
