  1. 16. Enzymes involved in heparan sulfate chain elongation : Function of a novel family of tumor suppressors?

    Author : Thomas Lind; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparan sulfate; biosynthesis; glycosyltransferase; EXT1; EXT2; UDP-glucosedehydrogenase; KfiC; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Abstract : Heparan sulfate (HS) is a glycosaminoglycan associated with many physiological functions such as regulation of growth factor action and cell adhesion. The HS polysaccharide is synthesized by alternating addition of D-glucuronic acid (GlcA) and N-acetyl-D-glucosamine (GlcNAc) units from the corresponding UDP-sugar precursors. READ MORE

  2. 17. Insights Into Protein Synthesis - Structural Aspects of Elongation Factor G and Fusidic Acid Inhibition

    Author : Sebastian Hansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molekylär biofysik; Structure chemistry; Strukturkemi; Molecular biophysics; Biologi; Biology; Biomedicinska vetenskaper; Biomedical sciences; conformational change; fusidic acid; protein synthesis; elongation factor G; crystal structures;

    Abstract : Elongation factor G (EF-G) catalyses the translocation step in protein synthesis on the ribosome. During this event the antibiotic Fusidic acid (FA) binds to and irreversably inhibits the release of the EF-G:GDP complex from the ribosome. READ MORE

  4. 19. Telomeres in ecology and evolution: Hypotheses and connections between telomere length, infections and life history trade-offs

    Author : David Gomez Blanco; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; telomeres; life history; telomere elongation; telomere shortening; early-life telomere length; critical threshold; malaria infection; great reed warbler; Acrocephalus arundinaceus;

    Abstract : Studying life history strategies is crucial for understanding the diversity among organisms. The trade-offs in traits related to survival, self-maintenance and reproduction play an important role in the variation of life histories and can be adjusted in response to environmental and physiological factors.

  5. 20. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation

    Author : Natasha Kamerlin; Christer Elvingson; Jan Forsman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; Brownian dynamics; polymer gel; microgel; spherical boundary conditions; hypersphere; core-shell; deswelling; mechanical properties; uniaxial elongation;

    Abstract : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.
