1. 16. Brain characteristics of memory decline and stability in aging : Contributions from longitudinal observations

   Författare :Sara Pudas; Jonas Persson; Lars Nyberg; Emrah Düzel; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; aging; episodic memory; individual differences; longitudinal assessment; magnetic resonance imaging; hippocampus; frontal cortex; Psychology; psykologi;

   Sammanfattning : Aging is typically associated with declining mental abilities, most prominent for some forms of memory. There are, however, large inter-individual differences within the older population. Some people experience rapid decline whereas others seem almost spared from any adverse effects of aging. LÄS MER

3. 17. The impact of criminal and externalizing behaviors on aging : Long-term associations with health and dementia

   Författare :Carmen Solares Canal; Henrik Larsson; Jonas Persson; Henrik Andershed; Björn Hofvander; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Older adults; aging; criminal behavior; externalizing behaviors; violent crime; dementia; Alzheimer s diseases; mental health; physical health; epidemiology;

   Sammanfattning : Previous studies have shown that criminal and other externalizing behaviors are associated with several adverse outcomes, but very little is known about the impact of these behaviors beyond middle adulthood. Few studies have explored how a life-course background of criminal and externalizing behaviors influence aging and more specifically, whether it is associated with the onset and development of different neurodegenerative, mental, and physical health disorders when aging.

4. 18. 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

5. 19. Links between Aging and Proteostasis Decline in Saccharomyces cerevisiae

   Författare :Veronica Andersson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aging; aggregates; proteostasis; proteasome; disaggregation; peroxiredoxins; asymmetric inheritance; S. cerevisiae;

   Sammanfattning : Proteins are continuously synthesized and degraded to meet the demands of the cell. Hence, a proper balance between synthesis, folding, disaggregation and degradation is of essence to ensure cell survival. Disruption of any part of this proteostasis network may have severe consequences for cellular fitness and longevity. LÄS MER
