  1. 16. alpha-synuclein: amyloid fibrils and interactions with lipid membranes

    Författare :Marija Dubackic; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alpha-synuclein; model lipid membranes; amyloid fibrils; Parkinson s disease; Lewy bodies; SANS; SAXS;

    Sammanfattning : The second most common neurodegenerative disease, Parkinson’s disease, is linked with an amyloid forming protein, alpha-synuclein. Hallmarks of Parkinson’s disease are progressive loss of dopaminergic neurons and accumulation of intraneuronal inclusions termed Lewy bodies. LÄS MER

  3. 17. Drug Partitioning into Natural and Artificial Membranes : Data Applicable in Predictions of Drug Absorption

    Författare :Caroline Engvall; Birgitta Tomkinson; Katarina Edwards; Sven Engström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Bilayer disk; Cholesterol; Drug partitioning; Drugs; Electrostatic effects; Immobilized liposome chromatography; Liposome; Membrane protein; Model membrane; Oligonucleotide-liposome complex; Phospholipid; Phospholipid bilayer; Proteoliposome; Surfactant; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : When drug molecules are passively absorbed through the cell membrane in the small intestine, the first key step is partitioning of the drug into the membrane. Partition data can therefore be used to predict drug absorption. LÄS MER

  5. 19. In vitro characterization of nanodrugs at model lipid membranes

    Författare :Rickard Frost; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; in vitro screening; nanomedicine; drug delivery; drug carrier; supported lipid bilayer; QCM-D; nanoparticle; cell membrane;

    Sammanfattning : The use of nano-sized drug carriers to improve the efficiency of drug delivery has become well established during the past decades. New nanoparticle (NP) formulations for the administration of biopharmaceuticals (e.g. proteins and peptides) emerge at an increasing rate and the need for methods to evaluate their properties is expanding.

  7. 20. Gas Adsorption and Permeation in MFI Zeolites and Membranes

    Författare :Sang Wirawan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite membranes; TPD; MFI zeolites; WGS membrane reactor; adsorption; FTIR spectra;

    Sammanfattning : The single and multi component gas adsorption behavior on silicalite-1 and cation exchanged MZSM-5 zeolites (M = H, Na, and Ba) were investigated by a step change response method. Temperature programmed desorption (TPD) and in-situ fourier transform infrared (FTIR) spectroscopy were also performed to study the type of adsorbed species and their thermal stabilities. LÄS MER
