1. 16. Phosphatidylethanol - formation and degradation in blood and organs

   Författare :Steina Aradottir; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostik; Public health; Diagnostics; organs; blood; HPLC; in vitro; in vivo; human; rat; phosphatidylethanol; phospholipase D; alcohol; ethanol; epidemiology; Folkhälsa; epidemiologi;

   Sammanfattning : Phosphatidylethanol (PEth) is an abnormal phospholipid formed exclusively by the action of phospholipase D (PLD) in the presence of ethanol. The degradation of PEth is slow and due to its accumulation in some cells the possibility to use PEth as marker of ethanol intake has been proposed. LÄS MER

3. 17. Effects of Dehydration and Blockade of the Renin-Angiotensin System in the One-humped Camel (Camelus dromedarius)

   Författare :Mahmoud Al Haj; Fred Nyberg; Santi Spampinato; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood; biochemical analysis; catecholamine; colorimetric assay; cortisol; dehydration; dromedary camel; glutathione; hematological analysis; HPLC; insulin- like growth factor-1; losartan; plasma; receptors; radioimmunoassay; serum; Pharmaceutical Science; Farmaceutisk vetenskap;

   Sammanfattning : The one-humped or the dromedarian camel is a pseudo-ruminant mammal, well adapted to the hot and dry climates of the desert. Its ability to withstand torrid heat and extreme desiccation is of paramount importance to its survival. LÄS MER

4. 18. Towards the Rational Design of Molecularly Imprinted Polymers

   Författare :Håkan S Andersson; Ann-Christin Koch-Schmidt; Ian A Nicholls; Klaus Mosbach; Richard F Venn; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermodynamics; Molecular Recognition; Polyvalency; Cooperativity; Electrostatic Interactions; Hydrophobic Effect; Chromatography; Frontal Analysis; HPLC; Spectroscopy; Molecularly Imprinted Polymer; Molecular Imprinting; Crown Ether; Template Polymerisation; Cyclodextrin; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik; molecular recognition; Biokemi;

   Sammanfattning : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. LÄS MER

5. 19. Exploring beta-mannan acting glycosidase families in hydrolysis and mannosyl transfer

   Författare :Simon Birgersson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; beta-mannanase; Transglycosylation; enzymatic synthesis; Enzyme synergy; enzyme engineering; MALDI-TOF; HPLC; NMR;

   Sammanfattning : The thesis revolves around the study of glycoside hydrolases (GH), specifically GH5 β-mannanases and GH36 α-galactosidase (I-III), as well as a GH130 mannoside phosphorylase (I, IV). These enzymes are investigated for their actions on and conversion of hemicellulosic β-mannan, including food-grade galactomannan and softwood galactoglucomannan, along with manno-oligosaccharides (MOS) derived from such polymers.

7. 20. The digestive machinery of a human gut bacterium : Structural enzymology of galactomannan utilisation

   Författare :Viktoria Bågenholm; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; Glycoside hydrolase; enzymology; structural biology; kinetics; HPLC; product profiles; structure-function;

   Sammanfattning : Human gut bacteria utilise different types of polysaccharides present in our diet. One of these polysaccharides is galactomannan. Many organisms in the phylum Bacteroidetes have gene clusters encoding for all proteins required for hydrolysis, binding and transport of one type of polysaccharide, called polysaccharide utilisation loci (PULs).
