Four integral membrane proteins, PomA, PomB, MotX, and MotY, are thought to be directly involved in torque generation of the Na(+)-driven polar flagellar motor of Vibrio alginolyticus. Our previous study showed that PomA and PomB form a complex, which catalyzes sodium influx in response to a potassium diffusion potential. PomA forms a stable dimer when expressed in a PomB null mutant. To explor...

Rotation of the sodium ion-driven polar flagellum of Vibrio alginolyticus requires the inner membrane sodium ion channel complex PomA/PomB and the outer membrane components MotX and MotY. None of the detergents used in this study were able to solubilize MotX when it was expressed alone. However, when co-expressed with MotY, MotX was solubilized by some detergents. The change in the solubility o...

In the framework of development multi-responsive polymer materials, a well-defined copolymer bearing supramolecular recognition units was designed based on 2-(dimethylamino)ethyl methacrylate (DMAEMA) and dialkoxynaphthalene-functionalized monomer (NaphtA). The host–guest interactions this P(DMAEMA-co-NaphtA) with electron-deficient CBPQT4+, 4Cl- cyclophane host were studied by 1H NMR spectrosc...

Imitating the natural "energy cascade" architecture, we present a single-molecular rod-like nano-light harvester (NLH) based on a cylindrical polymer brush. Block copolymer side chains carrying (9,9-diethylfluoren-2-yl)methyl methacrylate units as light absorbing antennae (energy donors) are tethered to a linear polymer backbone containing 9-anthracenemethyl methacrylate units as emitting group...

The introduction of high molecular weight poly(methyI methacrylate) or poly(butadiene-co-acrylonitrile) into ethyl 2-cyanoacrylate produced viscous adhesives with a homogeneous or heterogeneous structure after cure. Steel joints bonded with these adhesives are shown to have improved tensile shear strength, deformability and stress relaxation of bonds compared with pure cyanoacrylate adhesive. P...

The environmentally-friendly synthesis of epoxy-functional spherical nanoparticles has been achieved using polymerization-induced self-assembly (PISA) in aqueous solution. Firstly, a non-ionic hydrophilic stabilizer block, poly(glycerol monomethacrylate) (PGMA), was prepared by reversible addition–fragmentation chain transfer (RAFT) solution polymerization in ethanol. This water-soluble precurs...

In Sweden as well as in many other countries most materials currently used for dental restorations contain acrylate and methacrylate monomers (1). As a consequence of increased use of resin-based compounds, there has been an increase in reported cases of irritant and allergic contact dermatitis mainly among dental professionals (2-5). The most common agent causing dermatitis among dental profes...
