2. 1. Flow processing and gel formation for producing biopolymer drops with functional shapes and diffusion properties

   Author : Bernhard Walther; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; drop deformation; 4-roll mill; biopolymer; agarose; shear; Kappa-carrageenan; elongation; microstructure; flow processing; drop-shaping; rheology; poly ethyleneglycol ; diffusion; gelatine; NMR; gel formation; TEM; flow channel;

   Abstract : This thesis focuses on the development of novel processes which combine flow-induced drop deformation and simultaneous temperature-induced gel formation in order to create shaped biopolymer drops. The drops are functional in terms of rheology and diffusion properties, factors strongly influencing the consistency of food products and flavour or drug release. READ MORE

4. 2. Generic Properties of Polymer Solutions

   Author : Takashi Uematsu; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

   Abstract : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. READ MORE

5. 3. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes

   Author : Ákos Végvári; Douglas Westerlund; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; capillary electrophoresis; capillary electrochromatography; gel electrophoresis; agarose; polyacrylamide; b-cyclodextrin; DNA; peptide; glutathione; drug enantiomers; microchip; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Abstract : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. READ MORE

6. 4. Diffusion studies in gels using holographic laser interferometry

   Author : Charlotte Mattisson; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical potential; ionic strenght; pH; cubic phase; partition coefficient; holographic laser interferometry; holography; pullulan; lysozyme; BSA; macromolecules; diffusion; gel; Poisson-Boltzmann; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Abstract : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.

7. 5. Some Characteristics of Human Prostasomes and Their Relationship to Prostate Cancer

   Author : Göran Ronquist; Anders Larsson; Lena Carlsson; Alicia Llorente; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostasomes; prostate; prostate cancer; clusterin; antibodies; metastasis; exosomes; PC-3 cells; DNA vehicles; gene therapy; immunoblotting; mass spectrometry; agarose gel electrophoresis; vertebral metastasis.; Clinical chemistry; Klinisk kemi; Clinical Chemistry; klinisk kemi;

   Abstract : Background: The secretory epithelial cells of the prostate gland use sophisticated vehicles named prostasomes to relay important information to sperm cells in semen. This prostasome-forming and secretory ability of the epithelial cells is also preserved in poorly differentiated prostate cancer cells. READ MORE
