Introduction: In the present study, various formulations of cationic liposomes were designed and prepared using different cationic lipids. It was performed to assess the physicochemical properties, miRNA loading ability and cellular toxicity rates of liposomes in order to use in gene therapy. Methods: Different cationic liposome formulations (F1-F4) containing various cationic lipids, DOTAP, D...
The effects of mucosal application of 1 mg% Alcian blue (a trivalent cationic phthalocyanine dye) on functional and ultrastructural parameters of the isolated rabbit gallbladder have been studied. Apart from minor changes in the shape of the group of central microvilli observed in thin-section electron microscopy and scanning electron microscopy, the major ultrastructural change induced by Alci...
This work reports the behavior of montmorillonite–magnetite mixtures varying composition in aqueous dispersions and evaluates their adsorbing properties using a cationic organic pollutant, methylene blue (MB+), an anionic inorganic arsenate (As(V)), as species. The effects presence montmorillonite on As(V) adsorption by magnetite MB+ clay were specially addressed. simple mixture dispersion with...
This study investigates the production and performance of a novel nanofiltration membrane for removal cationic dye (Methylene blue) multivalent cations. These positively charged membranes are made by dispersing modified metal–organic framework, Cl-MIL-101(Cr), into polyvinyl alcohol matrix as skin layer. To this end, mobile anion (Cl−) embedded in MIL-101(Cr) structure plays role to create posi...
In the present study the authors investigated a set of three new zinc(II) phthalocyanines (zinc(II) tetranitrophthalocyanine (ZnTNPc), zinc(II) tetra(phenyloxy)phthalocyanine (ZnTPhOPc) and the tetraiodide salt of zinc(II)tetra(N,N,N-trimethylaminoethyloxy) phthalocyaninate (ZnTTMAEOPcI)) immobilized into Al-MCM-41 prepared via ship-in-a-bottle methodology. The samples were fully characterized ...
Innate sensory biases could play an important role in helping naı̈ve animals to find food. As inexperienced bees are known to have strong innate colour biases we investigated whether bumblebee (Bombus terrestris) colonies with stronger biases for the most rewarding flower colour (violet) foraged more successfully in their local flora. To test the adaptive significance of variation in innate colo...

In this study, the photodegradation and the mineralization of a cationic dye Methylene Blue (MB) from aqueous solution was investigated, in the presence of hydrogen peroxide, using a photocatalyst based on copper modified natural zeolite (Z-Cu). Comparative studies of photolysis, photocatalysis on the monocationic form of zeolite (Z-Na) and photocatalysis on Z-Cu, quantified in terms of process...
In this work, we report synthesis and characterization of Bi2O3 nanoparticles loaded on mesoporous MCM-41 nanoparticles by a simple solid-state dispersion (SSD) method. Monoclinic bismuth oxide nanoparticles were prepared by polyacrylamide gel method and used as loading materials on the prepared mesoporous MCM-41 as a supporting material. Fourier transform infrared spectroscopy (FT-IR), X-ray p...
