Lipophorin (Lp) is the main haemolymphatic lipoprotein in insects and transports lipids between different organs. In adult females, lipophorin delivers lipids to growing oocytes. In this study, the interaction of this lipoprotein with the ovaries of Rhodnius prolixus was characterised using an oocyte membrane preparation and purified radiolabelled Lp (125I-Lp). Lp-specific binding to the oocyte...

The current study presents synthesis and characterization of high impact polystyrene - TiO2 nanoparticles mixed matrix membranes for separation of carbon dioxide from nitrogen. The solution-casting method was used for preparation of membranes. The nano mixed matrix membranes were characterized using scanning electron microscopy to ensure the suitable dispersion of nano particles in high impact ...

The characterization of and construction of a new optical sensor based on the immobilization of Pyrocatechol Violet on a triacetylcellulose membrane was described to for the determination of bismuth (III) in real samples. The interaction between sensing membrane and bismuth (III) was caused at pH 3.80 in acetate buffer solution and the color changed from yellow to blue along with the appearance...

Coherent feedback stabilises a system towards target state without the need of measurement, thus avoiding quantum backaction inherent to measurements. Here, we employ optical coherent remotely cool nanomechanical membrane using atomic spins as controller. Direct manipulation atoms allows us tune from strong-coupling an overdamped regime. Making use full control offered by our system, perform sp...

PURPOSE To determine whether age-related changes in Bruch's membrane affect its permeability to macromolecules. Such changes have been postulated to underlie some pathologic manifestations of age-related macular degeneration. METHODS Bruch's membrane preparations were isolated from the macular region of donated human eyes of differing age and mounted in a modified Ussing chamber. Permeability...

The reported work is on the preparation and characterization of polyvinyl alcohol -g- Polyacrylic acid (PVA-g-PAA)/ Polybenzimidazole sulfone (PBIs) cation exchange membrane used for the electro dialysis of sodium chloride solution. The polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. The polymer ...

There is possibility of microbial contamination of any single-dose vials (SDVs), multiple-dose vials (MDVs) and admixtures (ADXs) during the preparation and injection to the patients that could be resulted in bloodstream infection. The goal of this study was to investigate the microbial contamination of MDVs and SDVs after multiple use and ADXs prepared by nursing staff in the treatment room ve...

Evaluation of the electrocatalyst performance data includes an electrode preparation step. Herein, we compare structural composition Fe–N–C materials, used to electrocatalyze oxygen reduction reaction in proton-exchange membrane fuel cells, before and after catalyst layer preparation. The effects this step on electronic structure local coordination Fe were investigated by X-ray absorption (XAS)...
