  2. 11. Lysosomal stability under the influence of oxidative stress and lipofuscin accumulation

    Author : Evalill Nilsson; Ulf Brunk; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Medicin;

    Abstract : The lysosome is the cellular organelle responsible for degradation and recycling of macromolecules through hetero- and autophagocytosis. It is generally considered a stable organelle that breaks down only late during cellular degeneration. READ MORE

  4. 12. Novel Metal-Mediated Organic Transformations : Focusing on Microwave Acceleration and the Oxidative Heck Reaction

    Author : Per-Anders Enquist; Mats Larhed; Anders Hallberg; Troels Skrydstrup; Uppsala universitet; []
    Keywords : Organic chemistry; palladium II ; oxidative Heck reaction; high-throughput-chemistry; microwave acceleration; dicobalt octacarbonyl; in situ carbonylation; urea; diaryl ketones; ESI-MS; Organisk kemi;

    Abstract : Transition metals have played an important role in synthetic organic chemistry for more than a century, and offer catalytic transformations that would have been impossible with classical chemistry. One of the most useful and versatile of the transition metals is palladium, which over the years has catalyzed many important carbon-carbon forming reactions. READ MORE

  5. 13. Oxidative stress, macrophages, iron, and atherosclerosis

    Author : Wei Li; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Macrophages have a great capacity to take up exogenous material, such as oxidatively modified low density lipoproteins (oxLDL) and different sources of iron containing structures. OxLDL is taken up into macrophage lysosomes by receptor-mediated endocytosis, but poorly degraded, resulting in foam-cell formation. READ MORE

  6. 14. Glutathione peroxidase and selenium in meat - Tissue and species variation, thermal stability and selenium speciation

    Author : Charlotte Daun; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nutrition; Näringslära; speciation of selenium; lipid oxidation; thermal stability; RN phenotype; ageing; meat; Glutathione peroxidase; selenium;

    Abstract : Lipid oxidation is a major problem in muscle foods, leading to a loss in quality and nutritional value. It occurs in raw meat but is usually more pronounced in cooked meat. Since the demands of consumers for ready-to-eat foods have increased, the control of off-flavour in cooked meat is an important industrial problem. READ MORE

  7. 15. STUDIES OF FACTORS AFFECTING INTRACELLULAR TOXICITY OF THE SCA7 DISEASE PROTEIN ATAXIN - 7 : FOCUS ON ATAXIN-7 DEGRADATION AND OXIDATIVE STRESS

    Author : Xin Yu; Anna-Lena Ström; Nico Dantuma; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyglutamine; SCA7; UPS; Autophagy; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Spinocerebellar ataxia type 7 (SCA7) is one of nine neurodegenerative disorders caused by expansion of CAG/polyglutamine repeats. Proteins carrying expanded polyglutamine (polyQ) domains are suggested to be resistant to degradation and aggregate. Furthermore, a negative correlation between aggregation and toxicity has been shown. READ MORE
