  2. 1. A Parametric Approach to Yeast Growth Curve Estimation and Standardization

    Author : Ilona Pylvänäinen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioscreen; Chapman-Richards model; growth curve; growth rate; lag time; optical density OD ; Saccharomyces cerevisiae; standardized curve; stationary phase OD increment; summary curve; optical density OD ;

    Abstract : The purpose of this thesis is to contribute to the understanding of yeast growth. It builds upon a dataset consisting of growth curves of 576 Saccharomyces cerevisiae mutants in eight different environments. The data will be a part of a publicly available phenotypic library, PROPHECY, containing growth curves and characteristics of viable S. READ MORE

  4. 2. Cell-Specific Ca2+ Response in Pancreatic ß-cells

    Author : Natalia Gustavsson; Per Lindström; Peter Bergsten; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heterogeneity; individual ß-cells; islets of Langerhans; cytoplasmic calcium; repetitive glucose stimulation; lag-time; cell-specific; glyceraldehyde; ketoisocaproic acid; tolbutamide; mitochondrial metabolism; Histology; Histologi;

    Abstract : Pancreatic ß-cells are heterogeneous in their secretory responsiveness, glucose sensitivity and metabolic rate. A diminished and delayed first-phase insulin release is an early sign of failing ß-cells in diabetes. READ MORE

  5. 3. LDL Oxidation Susceptibility and Its Relation To Antioxidants and Fatty Acids : A Clinical and Experimental Study

    Author : Bo Ziedén; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Atherosclerosis is an arterial disease characterized by lipid deposits in the artery wall. These lipid deposits partly consist of oxidatively modified low density lipoprotein (LDL). Several lines of evidence indicate a role of oxidized LDL in atherogenesis. READ MORE

  6. 4. Hidden in the Water : Development of screening strategies to identify new organic contaminants of emerging concern

    Author : Frank Menger; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Man-made chemicals enable and sustain our modern quality of life. These chemicals can, however, become contaminants of emerging concern (CECs). There is currently a considerable lag time between release of chemicals to the environment and their identification as CECs. READ MORE

  7. 5. To Fold or To Fibrillate? Serendipity in Stability Studies

    Author : Olga Szczepankiewicz; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein stability; protein reconstitution; protein aggregation; Monellin; PGB1; Split-GFP; Amyloid beta;

    Abstract : Proteins are complex structures and years of research have been spent on attempts to understand their complexity. The non-covalent interactions involved in protein folding are: hydrophobic effect, electrostatic interactions, van der Waals interactions and hydrogen bonding. READ MORE
