Introduction: Vaccine studies against Pseudomonas aeruginosa have often focused on outer membrane proteins (OPRs) due to their potent stimulation of the immune response. Using major outer membrane proteins of cell walls (mOMPs) of P. aeruginosa and other Gram-negative bacteria actively stimulate the immune system without any toxic side effects. Moreover, these antigens show immunological cross-...

UV-induced grafting technique was used as a flexible method for surface modification of Polysulfone (PSf) ultrafiltration (UF) membranes in order to prepare hydrophilic nanofiltration (NF) membranes. Flat sheet Polysulfone (PSf) ultrafiltration membranes were prepared via phase inversion method. N-methylene-2-pyrrolidone (NMP) and polyethylene glycol (PEG) of three different molecular weights (...

A flexible robot arm with strain gauges distributed on it is used as a sensing unit in determination of endpoint position and force of flexible manipulator. The position and orientation of the flexible arm is expressed as a function of the local curvature. An interpolation technique gave a continuous curvature function from a finite set of measurements made with strain gauges. The endpoint forc...

In the photosynthetic purple bacterium Rhodobacter (Rba.) sphaeroides, light is absorbed by membrane-bound light-harvesting (LH) proteins LH1 and LH2. LH1 directly surrounds the reaction center (RC) and, together with PufX, forms a dimeric (RC-LH1-PufX)2 protein complex. In LH2-deficient Rba. sphaeroides mutants, RC-LH1-PufX dimers aggregate into tubular vesicles with a radius of approximately ...

and increases the light absorption of the active material, which improves the overall device performance. Furthermore, paper is able to act as a good interspacing layer to prevent short-circuit problem commonly encountered in fabricating vertical devices with NCs on fl exible substrates. People have long used paper as a dielectric layer for energy storage devices [ 29,30 ] and fi eld effect tra...

We designed a flexible probe to record both neuroelectrical and neurochemical activities (Figure 1). This probe has four microelectrodes for neural recording and a fluidic channel covered with a semipermeable membrane; the membrane is used for microdialysis in the brain. We measured impedance of the electrodes, and examined the leakage of dialysate from the fluidic channel in vitro.
