1. 21. Structural and Functional Studies on Human Type 2 Cystatins

   Författare :Marcia Alvarez Fernandez; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical chemistry; Klinisk kemi; structural- functional relationships.; protein crystallography; enzyme kinetics; inhibitors; cathepsins; legumains; cystatins; cysteine peptidases;

   Sammanfattning : Proteolytic enzymes are enzymes that hydrolyze peptide bonds in peptides and proteins. This ability to carry out protein degradation is essential for many cellular and extracellular processes that occur in all living organisms. Cysteine peptidases constitute a class of proteolytic enzymes. LÄS MER

3. 22. Water-Metal Surfaces : Insights from core-level spectroscopy and density functional theory

   Författare :Theanne Schiros; Anders Nilsson; John Hemminger; Stockholms universitet; []
   Nyckelord :water; hydroxyl; metal; surfaces; x-ray spectroscopy; density functional theory; bonding; fuel cell; kemisk fysik; Chemical Physics;

   Sammanfattning : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. LÄS MER

4. 23. Extent and limitations of functional redundancy among bacterial communities towards dissolved organic matter

   Författare :Martin Andersson; Eva Lindström; Stuart Jones; Uppsala universitet; []
   Nyckelord :Dissolved organic matter; BCC; biodiversity; functional redundancy; Mikrobiologi; Microbiology;

   Sammanfattning : One of the key processes in the carbon cycle on our planet is the degradation of dissolved organic matter (DOM) in aquatic environments. The use of organic matter by bacteria links energy from DOM to higher trophic levels of the ecosystem when bacteria are consumed by other organisms. This is referred to as the microbial loop.

5. 24. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications

   Författare :Jonas Mindemark; Tim Bowden; Andrew Dove; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA condensation; gene delivery; ionomers; polyplexes; self-assembly; amphiphiles; biodegradable; biological applications of polymers; transfection; cyclic carbonate monomers; polycarbonates; semicrystalline polymers; click chemistry; triazoles; cycloaddition; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

   Sammanfattning : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. LÄS MER

7. 25. Health, physical ability, falls and morale in very old people: the Umeå 85+ Study

   Författare :Petra von Heideken Wågert; Yngve Gustafson; Lillemor Lundin-Olsson; Birgitta Lindmark; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aged; 80 and over; accidental falls; epidemiological studies; geriatric assessment; health status; morale; physical ability; population characteristics; reference values; Physiotherapy; Sjukgymnastik fysioterapi;

   Sammanfattning : The very old, aged 80 years and over, is the fastest growing age group today, and the demands for healthcare and services will be even higher in the future. It is, therefore, of great importance to advance our knowledge about this group. LÄS MER
