2. 1. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

   Author : Arieh Cohen; Avdelningen för arbets- och miljömedicin; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

   Abstract : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. READ MORE

4. 2. A close-up on neutrophils : Visualizing the mechanisms of their in vivo recruitment and function

   Author : Sara Massena; Mia Phillipson; Randall S. Jonhson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; chemokine; chemotactic gradient; citrullination; hypoxia; inflammation; intraluminal crawling; intravital imaging; PAD enzymes; permeability; proangiogenic; proinflammatory;

   Abstract : A successful immune response depends on prompt and sufficient recruitment of leukocytes from the circulation to infected or injured sites. Mobilization of leukocytes to hypoxic tissues is vital for angiogenesis, i.e. the formation of new blood vessels from preexisting vasculature, and thus crucial for tissue growth and regeneration.

5. 3. Microdialysis Sampling, Electrochemical Detection and Mass Spectrometry of Carbohydrates in Monitoring Bioprocesses

   Author : Nelson Torto; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; monosaccharides; membrane; IPED; ion spray; probe internal geometry; extraction fraction; electrochemical oxidation; electrochemical detection; disaccharides; desalting; carbohydrates; bioprocess monitoring; Cu; APCI; Au; MS; oligosaccharides; PAD; PEI; Analytical chemistry; Analytisk kemi;

   Abstract : This thesis addresses; (1) the microdialysis experiment, application and methodology to maximise its performance when sampling from enzymatic bioprocesses, (2) electrochemical detection and electrochemical oxidation of carbohydrates on Au as well as Cu electrodes in alkaline solutions, and (3) coupling and maximising the performance of a microdialysis sampling based high performance anion exchange chromatography-integrated pulsed electrochemical detection-mass spectrometry system. Studies were carried out to investigate the effect of temperature, analyte as well as biomatrix complexity, analyte concentration, permeability factors, protein(enzyme)-membrane interaction and membrane material on the performance of microdialysis sampling.

6. 4. Characterisation of the Substituent Distribution in Starch and Cellulose Derivatives

   Author : Sara Richardson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Analytisk kemi; Cationic amylopectin; Hydroxypropyl amylopectin; Ethyl hydroxyethyl cellulose; Substituent distribution; Enzymic degradation; HPAEC-PAD; MALDI-TOF-MS; ESI-MS; Kemi; Analytical chemistry;

   Abstract : Starch and cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution and properties is important in order to design modification processes so as to produce derivatives with the desired properties.

7. 5. Characterisation of starch: development of analytical methods

   Author : Gunilla Nilsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; substitution pattern; microdialysis; HPAEC-PAD; NMR; biosensor; IMER; potato amylopectin starch; amylose; amylopectin; chain length; Analytical chemistry; Analytisk kemi;

   Abstract : Starch, comprised of amylose and amylopectin, is a very complex biopolymer. Different methods are therefore needed for the investigation of the molecular structures of amylose and amylopectin. In this thesis analytical methods have been developed and various techniques were combined for the characterisation of starch. READ MORE
