The article presents the results of studies on the oxidation mechanism of 3-hydroxy-2,7-naphthalenedisulfonic acid disodium salt (R-salt) with oxygen in subcritical water. To this aim, a series of experiments were carried out which showed that at a temperature of 413 K and pH > 9 the oxidation r...

A new hollow fiber liquid-phase microextraction (HF-LPME) method has been developed for the extraction of a group of phthalic acid esters (PAEs) of interest from different water samples prior to gas chromatography tandem mass spectrometry analysis. HF-LPME was carried out using 1-octanol as extr...

In this work, comparative study between electrochemical processes such as electrocoagulation (EC), peroxi-coagulation (PC) and peroxi-electrocoagulation (PEC) was performed for the removal of phthalic acid (PA) and chemical oxygen demand (COD) from aqueous medium. Initially, acid treatment was s...

A new rapid, sensitive and selective colorimetric sensing platform for the detection of glutathione (GSH) in dietary supplements was developed by phthalic acid (PTA) assisted synthesis of silver nanoparticles (AgNPs). The di-carboxylic functional groups of PTA were used to modify the surface of ...

A homopolymer strategy was developed to synthesize temperature and pH/CO2 stimulus-responsive homopolymers. A new class of acrylamide monomers bearing oligo(ethylene glycol) unit and N,N-diethylaminoethyl group were designed and prepared through Aza-Michael addition reaction followed by amidatio...

The effects of various heterogeneous nucleating agents (i.e. sodium benzoate, talcum, dimethyl dibenzylsorbitol, and a combination of calcium stearate and pimelic acid) on the mechanical properties of heterophasic copolymer of isotactic polypropylene and ethylene–propylene rubber (iPP/EPR blend...

The effect of concentration on the light stabilising efficiency of three metal chelates in polypropylene film has been examined. Both the calcium and nickel complexes of bis(ethyl-3,5-di-tert-butyl-4-hydroxybenzyl) phosphonate (Irganox 1425 and Irgastab 2002, respectively) exhibit the same behav...

Isotropic epoxy-resin bonded magnets composed of different amounts of Magnequench MQP-B and strontium ferrite powders have been prepared using a compression molding technique. The magnetic parameters for magnets with different amounts of strontium ferrite and magnetization reversal processes hav...

A normal mode analysis was carried out for a monoclinic anhydrous zinc acetate crystal in which the acetate groups had bridging bidentate coordination forms, and spectral assignments were made. Based on the assignments, a relation between the coordination structure of the carboxylate groups arou...

It is shown that the carrier fluid has a marked effect on the performance of metallic stearates. Some metallic stearates in water provide improved tribological activities and thus their application in aqueous media may be useful in the reduction of pollution arising from oil components in many m...

A membrane reactor containing an immobilized heterogeneous catalyst is an alternative for traditional homogeneous-based catalyzed transesterification for biodiesel production. Major problems in homogeneous catalysis are related to catalyst recuperation and soap formation, which can be overcome b...

The dynamic modulus (G′) and the loss (G″) were measured as a function of temperature for strontium stearate which undergoes successive phase transitions from crystal (Cr)–unknown liquid crystalline (lc) (X), rhombohedral lc (R), body-centered cubic (Q) and hexagonal lc (H) phases. This Lette...

Pulmonary inflammation is a biological response to cadmium entering the body via the respiratory route. Systemic administration of this metal revealed the lungs as a significant site of its disposition. In this study, the presence of basic indicators of lung inflammation (leukocyte infiltration ...

Infiltration of circulatory inflammatory cells is a common histopathological finding in target organs following cadmium administration, but there is paucity of data concerning their activity. In this study, the effects of sublethal (1 mg/kg) cadmium on peripheral blood polymorphonuclear (PMN) ce...

ObjectiveTo investigate the abilities of two flavonoids - Garcinia biflavanol-1 (GB-1) and Garcinia biflavanol-2 (GB-2) from Garcinia kola (G. kola) in reducing cadmium-induced effects on raw U937 cells and U937-derived macrophages.

ObjectiveTo investigate the effect of the anthocyanin-rich extract of Hibiscus sabdariffa (H. sabdariffa) calyx on the viability of cadmium-treated U937 cells and cadmium-mediated activation of U937-derived macrophages.

ObjectiveTo examine the presence of gender differences in pulmonary inflammation evoked by acute systemic cadmium administration in rats.

This study investigates the effect of glycine on cadmium-induced alterations on the viability and activation of the cell line U-937. In this experiment, U-937 cells were pre-treated with 16 μM cadmium (as cadmium chloride). These cadmium-treated cells were later incubated with or without glycin...

A specific metal ion-responsive lipid liquid crystalline (LLC) dispersion system was fabricated, which can work in buffer solutions. The LLC matrix was prepared from phytantriol which spontaneously forms the reversed bicontinuous cubic phase in water, and a novel peptide–lipid conjugate (peplip...

Cadmium (Cd) is a heavy metal with several toxicities that have destructive effect on most organ systems. However, its toxic effects on human lipoproteins are largely remained unknown especially in hyperlipidemic zebrafish model. Treatment of human high-density lipoprotein (HDL) with cadmium chl...
