The aim of this study is to produce self-assembled structures with hydrophobic polypeptide cores via Reversible Addition–Fragmentation chain Transfer (RAFT) – mediated Polymerisation-Induced Self-Assembly (PISA).
The radical copolymerization of N-[3-(dialkylamino)-propyl]methacrylamides with a number (meth)acrylic amides and esters in organic solvents over wide range molar ratios has been studied. Co-polymerisation constants for five polymerisation systems 1,4-dioxane toluene have determined by the Feinman Ross method. influence solvent on kinetics studied monomers was found, which manifests itself chan...
Complex permittivity of conducting polypyrrole (PPy)-coated Nylon-Lycra textiles is measured using a free space transmission measurement technique over the frequency range of 1-18 GHz. The aging of microwave dielectric properties and reflection, transmission and absorption for a period of 18 months is demonstrated. PPy-coated fabrics are shown to be lossy over the full frequency range. The leve...
Abstract Red blood cells (RBCs) from patients with sickle cell disease (SCD) lyse in deoxygenated isosmotic non-electrolyte solutions. Haemolysis has features which suggest that it is linked to activation of the pathway termed Psickle. This pathway is usually described as a non-specific cationic conductance activated by deoxygenation, HbS polymerisation and RBC sickling. The current work addre...
α1-Antitrypsin is primarily synthesised in the liver, circulates to the lung and protects pulmonary tissues from proteolytic damage. The Z mutant (Glu342Lys) undergoes inactivating conformational change and polymerises. Polymers are retained within the hepatocyte endoplasmic reticulum (ER) in homozygous (PiZZ) individuals, predisposing the individuals to hepatic cirrhosis and emphysema. Latency...
In a cell-free system from neutrophil cytosol GTP(&ggr ;)S can induce an increase in the number of free filament barbed ends and massive actin polymerisation and cross-linking. GTP(&ggr ;)S stimulation was susceptible to an excess of GDP, but not Bordetella pertussis toxin and could not be mimicked by aluminium fluoride, myristoylated GTPgammaS.Gialpha2 or Gbeta1gamma2 subunits of trimeric G pr...
We have investigated amine([–NH2])-rich coatings in various cell-culture applications for several years, depositing films by plasma polymerisation from ethylene (C2H4)-N2 or C2H4–NH3 mixtures, respectively. More recently, vacuum-ultraviolet(VUV, < 200 nm) assisted photo-polymerisation has proven highly advantageous: Employing quasi-monochromatic Kr and Xe VUV sources, we have found the latter t...
ParA Walker ATPases form part of the machinery that promotes better-than-random segregation of bacterial genomes. ParA proteins normally occur in one of two forms, differing by their N-terminal domain (NTD) of approximately 100 aa, which is generally associated with site-specific DNA binding. Unusually, and for as yet unknown reasons, parA (incC) of IncP-1 plasmids is translated from alternativ...
