  2. 1. Glucose- and hypoxia-regulated insulin gene expression

    Author : Linda Tillmar; Jens Höiriis Nielsen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; islet; beta-cell; insulin; mRNA stability; PTB; glucose; hypoxia; mTOR; p70s6k; ceramide; redox; ROS; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Although extensively studied, there are still many unanswered questions regarding the exact regulation of insulin gene expression. This is important to further investigate since it will hopefully help us understand the pathophysiology of some types of diabetes. READ MORE

  4. 2. Unravelling protein stability and aggregation

    Author : Tanja Weiffert; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein aggregation; amyloid beta peptide; protein stabilization; split GFP; monellin; secretagogin; ; aggregation kinetics; toxicity; aggregation mechanism; coaggregation;

    Abstract : Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. READ MORE

  5. 3. Peroxiredoxins in Redox Signaling and Aging

    Author : Friederike Roger; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aging; Peroxiredoxin; Redox Signaling; Caloric restriction; light sensing;

    Abstract : Peroxiredoxins have emerged as conserved modulators of the rate of aging in yeast and multicellular organisms and play a role in lifespan extension through the anti-aging intervention caloric restriction. Yet, it is not clear through what mechanism peroxiredoxins extend lifespan. READ MORE

  6. 4. Electrolyte-Based Dynamics: Fundamental Studies for Stable Liquid Dye-Sensitized Solar Cells

    Author : Jiajia Gao; Lars Kloo; Elizabeth Gibson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitized solar cells; Stability; Electrolyte; Cobalt redox couples; Additives; Kemi; Chemistry;

    Abstract : The long-term outdoor durability of dye-sensitized solar cells (DSSCs) is still a challenging issue for the large-scale commercial application of this promising photovoltaic technique. In order to study the degradation mechanism of DSSCs, ageing tests under selected accelerating conditions were carried out. READ MORE

  7. 5. Redox Reactions of NO and O2 in Iron Enzymes : A Density Functional Theory Study

    Author : Mattias Blomberg; Per Siegbahn; Adrian Mulholland; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzyme catalysis; redox reactions; cytochrome oxidase; nitric oxide reductase; hyponitrous acid anhydride; peroxynitrite; myoglobin; prostaglandin synthase; PGHS; NO; N2O; O2; CO; Chemical physics; Kemisk fysik;

    Abstract : In the present thesis the density functional B3LYP has been used to study reactions of NO and O2 in redox active enzymes.Reduction of nitric oxide (NO) to nitrous oxide (N2O) is an important part in the bacterial energy conservation (denitrification). READ MORE
