The ability of Congo red to form complexes with α-proteins, human growth hormone and human interferon-α2b, was found by absorption difference spectroscopy. A human growth hormone– Congo red complex was isolated by gel-permeation chromatography, and its visible absorption spectrum was registered in comparison to free dye. The ability of Congo red to induce dimerization of human growth hormone wa...

The carbon dioxide-assisted polymer compression method is used to create porous products with laminated fiber sheets that are crimped in the presence of dioxide. In this method, fibers oriented sheet-spread direction, and intersections upper lower crimped, leading several within product. This type orientation a material anisotropic. A dye solution was injected via syringe into product made poly...

Water contaminated with low concentrations of pollutants is more difficult to clean up than that high pollutant content levels. Membrane separation provides a solution for removing from water. However, membranes are prone fouling, losing performances over time. Here we synthesized neutral (IM-NH2) and positively charged (IL-NH2) imidazole derivatives chemically functionalize membranes. With dis...

Novel synthetic mimics of antimicrobial peptides have been developed to exhibit structural properties and antimicrobial activity similar to those of natural antimicrobial peptides (AMPs) of the innate immune system. These molecules have a number of potential advantages over conventional antibiotics, including reduced bacterial resistance, cost-effective preparation, and customizable designs. In...

the aim of the present study was to investigate the influence and the mechanisms of cineoleand terpineol on the in-vitro transdermal delivery of huperzine a from microemulsions, andtheir potential synergistic effect on the permeation enhancement. the transdermal deliveryof huperzine a from microemulsions with different concentrations of cineole and terpineolthrough the rat abdominal skin was de...

We have examined the kinetics by which FM1-43 escapes from individual synaptic vesicles during exocytosis at hippocampal boutons. Two populations of exocytic events were observed; small amplitude events that lose dye slowly, which made up more than half of all events, and faster, larger amplitude events with a fluorescence intensity equivalent to single stained synaptic vesicles. These populati...
