2. 1. Chiral recognition on cellulases : The active sites of the enzymes are involved

   Author : Hongbin Henriksson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Abstract : Two cellobiohydrolases (CBH I and CBH II) and endoglucanase I (EG I) fromTrichoderma reesei, and CBH 58 from Phanerochaete chrysosporium were immobilized onsilica as chiral stationary phases (CSPs) in HPLC for enantioseparation of a group ofpharmaceutical compounds. CBH I and CBH 58 wore excellent chiral selectors for β-adrenergic blocking agents, whereas CBH II displayed good enantioselectivity for someother compounds The CBHs share the common feature that their active sites are located intunnels.

4. 2. Protein folding, stability and recognition

   Author : Jianxin Duan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Protein; folding; stability; recognition; molecular dynamics; protein-DNA interactions; simulation;

   Abstract : Proteins make up for most of the dry mass of a cell and they are highly involved in virtually all cellular processes. The importance of the proteins is reflected by frequent association between dysfunctional proteins and diseases. Proteins have also wide applications in industries. READ MORE

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical exchange; Conformational entropy; Entropy; Galectin-3; Isothermal Titration Calorimetry; ITC; Model-free formalism; Molecular recognition; Nuclear Magnetic Resonance; NMR; PGB1; Protein dynamics; Protein–ligand interactions; Proton-transfer reactions; Spin relaxation; Viscosity; Chemical exchange; Conformational entropy; Entropy; Galectin-3; Isothermal Titration Calorimetry; ITC; Model-free formalism; Molecular recognition; Nuclear Magnetic Resonance; NMR; PGB1; Protein dynamics; Protein–ligand interactions; Proton-transfer reactions; Spin relaxation; Viscosity;

   Abstract : Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial protein G (PGB1).

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

   Author : Håkan S Andersson; Ann-Christin Koch-Schmidt; Ian A Nicholls; Klaus Mosbach; Richard F Venn; Tillämpad biokemi; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. Pattern Recognition Methods for Oral Lesion Classification using Digital Color Images

   Author : Artur Chodorowski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oral lesions; supervised classification; pattern recognition; computer-aided diagnosis; support vector machines; color; cancer; shape;

   Abstract : The present thesis addresses the development and application of pattern recognition methods for classification of oral lesions using digital color images as input. The human oral cavity is a site of numerous diseases and two of the common and visually similar lesions are oral leukoplakia and oral lichenoid reactions. READ MORE
