2. 1. Separation of peptides by capillary electrophoresis : Application of chemometrics for evaluation of separation performance in micellar electrokinetic chromatography

   Author : Margrét Thorsteinsdóttir; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

   Abstract : The separation of enkephalin-related peptides and protein kinase A peptide substrates werestudied in micellar electrokinetic chromatography and compared with capillary zoneelectrophoresis. Special interest was focused on systems where the electroosmosis wasreversed in combination with neutral micellar agents. READ MORE

4. 2. Post-traumatic Stress Disorder – Assessment of current diagnostic definitions

   Author : Kristina Bondjers; Filip Arnberg; Mimmie Willebrand; Mark Shevlin; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PTSD; Complex PTSD; Post-traumatic Stress; Psychological assessment; DSM-5; ICD-11; Confirmatory factor analysis; Latent class analysis; Structural equation modelling; psychometric; psychiatric diagnoses; Psychiatry; Psykiatri;

   Abstract : Post-traumatic stress disorder (PTSD) is a debilitating condition that may arise after exposure to shocking, frightening, or dangerous events. Hallmark symptoms are re-experiencing, avoidance, and hyperarousal. Other common symptoms are more ancillary and overlap with other psychiatric disorders (e.g. READ MORE

5. 3. Standardization of Islet Isolation and Transplantation Variables

   Author : Andrew S Friberg; Olle Korsgren; Daniel Brandhorst; Paul R. V. Johnson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet isolation; standardization; enzyme; gradient separation; digital imaging analysis; DIA; transplantation outcome; islet transplantation; prediction; Medical technology; Medicinsk teknik; Medical Cell Biology; Medicinsk cellbiologi; Computerized Image Processing; Datoriserad bildbehandling;

   Abstract : Currently, the transplantation of islets of Langerhans is a viable means to maintain control of blood sugar levels and reduce the risk of hypoglycemia in defined populations with brittle type I diabetes mellitus or those requiring pancreatectomy. However, the process of islet isolation is highly variable and not all isolations result in islet numbers or quality suitable for transplantation. READ MORE

6. 4. On the phase behaviour of hydrogels : A theory of macroion-induced core/shell equilibrium

   Author : Jonas Gernandt; Per Hansson; Göran Frenning; Renko de Vries; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polymer; polyelectrolyte; surfactant; thermodynamics; elasticity; Pharmaceutical Science; Farmaceutisk vetenskap;

   Abstract : Colloidal macroions are known to interact very strongly with oppositely charged polyionic hydrogels. Sometimes this results in a non-uniform distribution of the macroions within the gel, a phenomenon that is not fully understood. READ MORE

7. 5. Retrogradation Properties of Starch

   Author : José Silverio; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; lipids; degree of polymerization DP ; isothermal microcalorimetry; differential scanning calorimetry DSC ; crystallinity; amylose; amylopectin; gelatinization; starch; retrogradation; temperature cycling; PCA; Food and drink technology; Livsmedelsteknik;

   Abstract : The main purpose of this thesis was to examine various factors influencing starch retrogradation. The reassociation events of starch, which are closely linked to the staling of bakery products, were mainly studied by thermal analysis. Some aspects of starch gelatinization are also included.
