    Sammanfattning : Background and Objectives: With an ageing population, the number of older persons with substance use problems, particularly problematic alcohol use, is increasing. Despite grow­ing recognition of the negative consequences of problematic alcohol use on older persons, there is a dearth of knowledge about the alcohol use profiles and the dimensionality of alcohol problems in older people.

  3. 2. Proteomics in biomarker research : Insights into the effects of aging and environment on biological systems

    Författare :Hanna Amelina; Susana Cristobal; Jean-Charles Sanchez; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; proteomics; biomarker; peroxisomes; 2-dimensional gel electrophoresis 2-DE ; mass spectrometry MS ; aging; marine pollution; Biochemistry; Biokemi; Environmental toxicology; Miljötoxikologi; Cell and molecular biology; Cell- och molekylärbiologi; Biochemistry; biokemi;

    Sammanfattning : Proteomics is the global analysis of proteins that covers a broad range of technologies aimed at determining the identity and quantity of proteins expressed in the cell, their three-dimensional structure and interaction partners. In contrast to genome, proteome reflects more accurately on the dynamic state of the cell, tissue, or an organism. LÄS MER

  4. 3. Caulobacter crescentus folding machines at the interface of inheritance, cell division, and energy metabolism

    Författare :Kristen Schroeder; Kristina Jonas; Pierre Genevaux; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chaperones; DnaK; chaperonin; GroESL; protein quality control; protein folding; stress response; cellular aging; cell division; bacterial respiration; Caulobacter crescentus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : All living cells must perform essential biological processes while monitoring and responding to environmental cues. Bacteria are accessible experimental systems in which to study the function of conserved central processes. LÄS MER

  5. 4. Aging effects on commercial lean NOx trap catalysts

    Författare :Jesus De Abreu Goes; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aging; thermal degradation; sulfur poisoning; characterization; commercial lean NOx traps; NOx storage and reduction;

    Sammanfattning : As a countermeasure to global warming, vehicles with low carbon emissions are being investigated by promoting lean-burn engines and high combustion efficiencies. However, one limitation to the increasing use of these engines is the need to develop corresponding catalytic systems for controlling the nitrogen oxide (NOx) emissions in their lean exhaust.

  7. 5. On protein oxidation, lifespan and aging in Saccharomyces cerevisiae

    Författare :Hugo Aguilaniu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asymmetric cell division; protein oxidation; yeast; aging; signalling pathways;

    Sammanfattning : In this thesis, we have investigated the physiology of protein oxidation and its possible role in the aging of the yeast Saccharomyces cerevisiae. There are two ways to measure yeast aging. First, they can only divide a finite number of times even when all nutrients necessary for division are provided. This is replicative aging. LÄS MER
