  1. 31. Lipid-Based Surface Modifications: towards the Development of Membrane-Protein Arrays

    Författare :Indriati Pfeiffer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA-array; cholesterol-DNA; EIS; membrane proteins; lipid vesicles; QCM-D; supported lipid bilayer;

    Sammanfattning : Mimics of the natural cell membrane, such as lipid vesicles and supported lipid membranes, have gained significant attention in recent years. This is primarily due to their ability to provide scientists with a model system allowing a large arsenal of scientific tools to be used in studies of biological reactions that are naturally controlled by the cell membrane and its components.

  3. 32. Cellular targets of HAMLET, their role in tumor cell death and therapeutic potential

    Författare :Aftab Nadeem; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer therapy; colon cancer; bladder cancer; cell death; HAMLET; alpha-lactalbumin; oleate; membrane lipids; nucleotide-binding protein; Ras GTPases; alpha-helical peptides;

    Sammanfattning : Protein-lipid complexes have broad and specific effects against cancers of different origins. HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells) is a complex of partially unfolded α-lactalbumin and oleic acid that kills a wide range of tumor cells but leaves healthy differentiated cells unaffected.

  4. 33. Sustainable membrane fabrication using greener solvents

    Författare :Norafiqah Ismail; Naser Tavajohi Hassan Kiadeh; Nils Skoglund; Lidietta Giorno; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Technologies based on polymeric membranes have diverse applications in purification, desalination, and decontamination processes. However, current membrane production techniques are neither sustainable nor environmentally benign. LÄS MER

  5. 34. Biological membrane interfaces involved in diseases : a biophysical study

    Författare :Fredrick Lindström; Gerhard Gröbner; Dick Sandström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid-state NMR; DSC; Amyloid-beta peptide; Nociceptin; DMPC; DMPG; DDAB; peptide-lipid interaction; branched-chain fatty acid.; Biophysical chemistry; Biofysikalisk kemi;

    Sammanfattning : Interactions between peptides and biological lipid membranes play a crucial role in many cellular processes such as in the mechanism behind Alzheimer’s disease where amyloid-beta peptide (Abeta)is thought to be a key component. The initial step of binding between a surface active peptide and its target membrane or membrane receptor can involve a non specific electrostatic association where positively charged amino acid residues and a negatively charged membrane surface interact.

  7. 35. Zeolite Membrane Separation at Low Temperature

    Författare :Pengcheng Ye; Linda Sandström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The energy consumption of separation process accounts for a large part inchemical industry. Membrane processes use much less energy compared to thecurrently used thermally driven processes and could thereby reduce energyconsumption in industry significantly. LÄS MER
