    Abstract : Gasfasympning är en del i den moderna strategin för optimering av den molekylära designen av biomaterial. Kovalent ytmodifiering med hydrofila vinylmonomerer och koppling med bioaktiva grupper används för att öka biokompatibiliteten och bioaktiviteten hos biomaterialen.. READ MORE

  4. 2. Cell Contacts and Airway Epithelial Damage in Asthma

    Author : Shahida Shahana; Godfried Roomans; Rolf Odselius; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anatomy; Desmosomes; tight junctions; major basic protein; eosinophil; cytokines; epithelial damage.; Anatomi; Anatomy; Anatomi;

    Abstract : Airway epithelial damage is commonly found in asthma patients. Epithelial damage was investigated with special reference to contacts between epithelial cells.Eosinophils, common in allergic asthma, secrete cationic proteins, particularly major basic protein (MBP). READ MORE

  5. 3. Poly-and oligothiophenes : Optical probes for multimodal fluorescent assessment of biological processes

    Author : Karin Magnusson; Peter Nilsson; Per Hammarström; Thomas Borén; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : One interesting class of molecules in the research field of imaging biological processes is luminescent conjugated polythiophenes, LCPs. These fluorescent probes have a flexible backbone consisting of repetitive thiophene units. READ MORE

  6. 4. Poly(A)-specific Ribonuclease (PARN) : Structural and Functional Studies of Poly(A) Recognition and Degradation

    Author : Niklas Henriksson; Anders Virtanen; Marvin Wickens; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Regulation of mRNA degradation is a powerful way for the cell to regulate gene expression. A critical step in eukaryotic mRNA degradation is the removal of the poly(A) tail at the 3'-end of the mRNA. READ MORE

  7. 5. Bioresorbable copolymers with tailored properies : innovative materials för soft tissuel engineering

    Author : Natalia Andronova; Ann-Christine Albertsson; Pieter Dijkstra; KTH; []
