1. 21. Adult Neural Stem Cells-Influence of Stroke, Inflammation and Aging

   Författare :Henrik Ahlenius; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammation; Neural stem cells; adult; neurogenesis; stroke; aging; TNF-R1; TNF-α;

   Sammanfattning : Neural stem cells (NSCs) in the embryo generate neurons, astrocytes and oligodendrocytes, the principal cells of the central nervous system (CNS), which contribute to the full diversity of the brain. Some NSCs persist in the adult brain and ensures neurogenesis throughout adult life in the subventricular zone (SVZ) and the subgranular zone (SGZ). LÄS MER

3. 22. Mitochondrial translation and its impact on protein homeostasis and aging

   Författare :Tamara Suhm; Martin Ott; Aleksandra Trifunovic; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mitochondrial ribosome; mitochondrial translation accuracy; mitochondrial communication; interorganellar communication; stress signaling; proteostasis; aging; yeast genetics; mitochondrial protein quality control; mitochondrial membrane protein insertion; Biochemistry; biokemi;

   Sammanfattning : Besides their famous role as powerhouse of the cell, mitochondria are also involved in many signaling processes and metabolism. Therefore, it is unsurprising that mitochondria are no isolated organelles but are in constant crosstalk with other parts of the cell. LÄS MER

4. 23. 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

5. 24. Proteostasis and Aging in Saccharomyces cerevisiae - The role of a Peroxiredoxin

   Författare :Sarah Hanzén; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aging; Caloric restriction; Oxidative stress; Peroxiredoxins; Proteostasis; Protein aggregates; Ubiquitin-proteasome system;

   Sammanfattning : Aging is characterized by a progressive decline in physiological functions that limits biological processes, increases the risk of disease, and ultimately leads to death. At the cellular level, aging is associated with accumulation of damaged components, including proteins, indicating that protein homeostasis (or proteostasis) fails to maintain the integrity and functionality of the proteome as cells age.

7. 25. Aging and heat-sealing properties of films based on wheat gluten

   Författare :Sung-Woo Cho; Mikael Hedenqvist; Minna Hakkarainen; Mikael Lindström; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheat gluten; aging; migration; opacity; heat sealability; shear strength; Polymer chemistry; Polymerkemi;

   Sammanfattning : Recently the research interest of the possibility of using wheat gluten (WG) as packaging material has greatly increased due to its combination of high gas barrier, attractive mechanical, film-forming and renewable properties. The source is also readily available and inexpensive on a worldwide basis. LÄS MER
