11. Lysosomal stability under the influence of oxidative stress and lipofuscin accumulation
Sammanfattning : 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. LÄS MER
12. Novel Metal-Mediated Organic Transformations : Focusing on Microwave Acceleration and the Oxidative Heck Reaction
Sammanfattning : 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. LÄS MER
13. Oxidative stress, macrophages, iron, and atherosclerosis
Sammanfattning : 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. LÄS MER
14. Glutathione peroxidase and selenium in meat - Tissue and species variation, thermal stability and selenium speciation
Sammanfattning : 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. LÄS MER
15. STUDIES OF FACTORS AFFECTING INTRACELLULAR TOXICITY OF THE SCA7 DISEASE PROTEIN ATAXIN - 7 : FOCUS ON ATAXIN-7 DEGRADATION AND OXIDATIVE STRESS
Sammanfattning : 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. LÄS MER
