1. 1. Protein complexes : assembly, structure and function

   Författare :Kristina Wilhelm; Ludmilla Ludmilla Morozova-Roche; Catharina Svanborg; Umeå universitet; []
   Nyckelord :HAMLET; ELOA; lysozyme; amyloid; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning :  Most proteins must fold into their native conformations to fulfil their biological functions. Failure of proteins to fold leads to cell pathology and a broad range of human diseases referred to as protein misfolding disease, e.g., Alzheimer’s disease, Parkinson’s disease, and type II diabetes.

3. 2. Zero-Field Splitting in Gd(III) complexes : Towards a molecular understanding of paramagnetic relaxation

   Författare :Shehryar Khan; Michael Odelius; Arnold Maliniak; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zero-Field Splitting; Relaxation; Quantum Chemistry; Molecular Dynamics; Gd III ; kemisk fysik; Chemical Physics;

   Sammanfattning : The prime objectives of contrast agents in Magnetic Resonance Imaging(MRI) is to accelerate the relaxation rate of the solvent water protons in the surrounding tissue. Paramagnetic relaxation originates from dipole-dipole interactions between the nuclear spins and the fluctuating magnetic field induced by unpaired electrons. LÄS MER

4. 3. Role of respiratory supercomplexes : Electronic connection between complexes III and IV

   Författare :Agnes Moe; Peter Brzezinski; James A. Letts; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electron transfer; cytochrome c oxidase; cytochrome bc1; respiratory supercomplex; bioenergetics; membrane protein; biokemi; Biochemistry;

   Sammanfattning : In the final step of cellular respiration, electrons are transferred through the respiratory chain to reduce molecular oxygen to water. The energy released in this chain is used to maintain a proton electrochemical gradient across the cell membrane, which is used, for example, by the ATP synthase to produce ATP. LÄS MER

5. 4. Modeling Photofunctional Transition Metal Complexes

   Författare :Iria Bolano Losada; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; earth-abundant; molecular dynamics; quantum chemistry; photosensitizer; photophysics; photochemistry; solar fuels; solar energy conversion; transition metal complexes;

   Sammanfattning : Transition metal complexes play a crucial role in solar energy conversion. These coordination compounds have promising applications in dye-sensitized solar cells and photocatalysis, with particular interest in solar fuel production. LÄS MER

7. 5. Streptococcus pyogenes - a manipulator of human defences

   Författare :Fredrik Kahn; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pyogenes; M protein; neutrophils; platelets; platelet-neutrophil complexes; fibrinogen; IgG; abscess; venous thrombosis; heparin binding protein; thrombocytopenia;

   Sammanfattning : Streptococcus pyogenes is a major human pathogen with more than 500 000 casualties annually of which at least 163 000 are due to invasive infections. The remainder is due to post-streptococcal complications with rheu¬matic heart disease constituting the majority. S. LÄS MER
