    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; Planctomycetes; Gemmataceae; functional organization; signalling; protein interaction; peptidoglycan; membranes; cell division; radiation tolerance; Pfam; SCOP; comparative genomics; protein architecture; domain shuffling and orthologous clustering; Bioinformatics; Bioinformatik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : Bacteria of the family Gemmataceae belong the phylum Planctomycetes and are remarkable because of their complex cellular architectures, previously considered to be traits exclusive to eukaryotes. This thesis provides clues to the atypical cell envelope, the enhanced radiotolerance and the amazing cellular complexity of these bacteria. LÄS MER

  3. 22. The impact of early nutrition on extremely preterm infants

    Författare :Elisabeth Stoltz Sjöström; Magnus Domellöf; Inger Öhlund; Deborah O'Connor; Umeå universitet; []

    Sammanfattning : Background Modern neonatal care has improved the survival rate of extremely preterm infants. These infants are at high risk of malnutrition and growth failure during 3-4 months of hospital care. LÄS MER

  4. 23. Self-assembly of amyloid-β peptides in the presence of metal ions and interacting molecules – a detour of amyloid building blocks

    Författare :Cecilia Mörman; Astrid Gräslund; Daniel Otzen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biophysics; Alzheimer’s disease; protein aggregation; amyloid formation; amyloid-β peptide; aggregation kinetics; interactions; metal ions; designed peptide constructs; Tau protein; NMR; circular dichroism; fluorescence spectroscopy; Biophysics; biofysik;

    Sammanfattning : Misfolding of proteins into amyloid structures is implicated as a pathological feature in several neurodegenerative diseases and the molecular causes are still unclear. One typical characteristic of Alzheimer’s disease is self-assembly and accumulation of soluble amyloid-β (Aβ) peptides into insoluble fibrils and plaques. LÄS MER

  5. 24. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties

    Författare :Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Sammanfattning : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

  7. 25. Synthesis, Characterisation and Application of 68Ga-labelled Macromolecules

    Författare :Irina Velikyan; Bengt Långström; Mats Bergström; Helmut Maecke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; 68Ga; 68Ge 68Ga generator; radiolabelling; microwave heating; specific radioactivity; peptide; protein; antibody; oligonucleotide; positron emission tomography; tumour; Kemi; Chemistry; Kemi;

    Sammanfattning : The positron emitting radionuclide 68Ga (T1/2 = 68 min) might become of practical interest for clinical positron emission tomography (PET). The metallic cation, 68Ga(III), is suitable for complexation with chelators, either naked or conjugated with biological macromolecules. LÄS MER
