Publisher SummaryPoly (arylene ether sulfone)s, (PAES)s, have been known since 1970's. They are tough linear polymers and possess a number of attractive features, such as excellent high-temperature resistance, good electrical properties, and good hydrolytic stability. PAESs are also known a...
In this paper, composite reverse osmosis (RO) membranes made from sulfonated poly(arylene ether sulfone) containing amino groups (aPES) and hyper-branched aromatic polyamide-grafted silica (HBP-g-silica) were prepared, with the aim of enhancing chlorination resistance and improving membrane perf...
Poly(aryl ether ketones) belong to the class of engineering polymers. Refined varieties of poly(ether ether ketone)s include the poly(ether ketone ketone) (PEKK), poly(ether ether ketone ketone) (PEEKK) and poly(ether ketone ether ketone ketone) (PEKEKK) polymer type. Special additives like Melt...
In this work, the organic-inorganic hybrid membranes were prepared. The synthesis and properties of the hybrid membranes were investigated. The sulfonated poly(arylene ether ketone sulfone) containing amino groups (Am-SPAEKS) was synthesized by nucleophilic polycondensation. The sol-gel method w...
This chapter describes the monomers, properties, and applications of Poly(arylene ether sulfone)s. The synthesis and the modification techniques concerning PES are reviewed. Poly(ether sulfone)s can be obtained either by a conventional step-growth polycondensation or by a chain-growth polyconden...
The synthesis and properties of novel cross-linked composite sulfonated poly (aryl ether ketone sulfone) containing multiple sulfonic side chains as proton exchange membranes were investigated. The multiple side-chain membranes were prepared by direct polycondensation and simple free radical rea...
The ion-associate complexes of lignocaine hydrochloride (Lig.Cl) with ammonium reineckate (Rk) or sodium cobaltithiocyanate, and that of amprolium hydrochloride (Amp.Cl) with ammonium reineckate, have been prepared. The precipitated ion-associates were subjected to elemental analyses, infrared a...
Arsanilic acid (ASA) and amprolium hydrochloride (AMP) are widely used as feed additives to control coccidial intestinal parasites and improve feed efficiency, but due to low metabolism most of the drugs are excreted by the animals unchanged and eventually end up in wastewaters. Little is known ...
Five simple, specific, accurate and precise UV-spectrophotometric methods are adopted for the simultaneous determination of Amprolium hydrochloride (AMP) and Ethopabate (ETH), a binary mixture with overlapping spectra, without preliminary separation. The first method is first derivative of the r...
As a consequence of the finding of veterinarian drugs in food European Community banned several compounds like coccidiostats as amprolium (APL). This antibiotic has been used as a preventive and clinical anticoccidial drug in chicken. The 2005/187/CE, 2005/925/EC Recommendations ban the use of a...
Three novel amprolium HCl (AMP)-selective electrodes were investigated with 2-nitrophenyl octylether as a plasticiser in a polymeric matrix of polyvinyl chloride (PVC). Sensor I was fabricated using potassium tetrakis(4-chlorophenyl) borate (TpClPB) as a cationic exchanger without incorporation ...
We present a fast liquid chromatography–tandem mass spectrometry (LC–MS/MS) method for the analysis of the coccidiostat amprolium in food samples. Tandem mass spectrometry in a triple quadrupole was used for quantitative purposes, and the information from multiple-stage mass spectrometry in an...
Two sensitive and selective spectrofluorimetric methods are proposed to determine ethopabate (ETH) and amprolium hydrochloride (AMP). First derivative synchronous spectrofluorimetry determines the natively fluorescent ethopabate at 288 nm in presence of amprolium hydrochloride which is a non flu...
This study evaluated the efficacy of two different doses of amprolium in goats heavily infected with pathogenic Eimeria species. Forty Boer goat kids ranging from 3 to 5 months of age with naturally occurring coccidiosis were randomly divided into 2 groups and treated orally with amprolium at do...
Coccidiosis is an important disease of young goats leading to weight loss, diarrhea, and death. In the USA, both ionophores and decoquinate are labeled for prevention of coccidia in goats. However, there are no drugs approved for treatment of clinical cases of coccidiosis in this species. Amprol...
Erythrocytes are both an important source and target of reactive oxygen species in sickle cell disease. Levels of glutathione, a major antioxidant, have been shown to be decreased in sickle erythrocytes and the mechanism leading to this deficiency is not known yet. Detoxification of reactive oxy...
Glutathione (GSH) is the most abundant low-molecular-mass thiol within cells and one of the major antioxidant compounds in body fluids. Under pro-oxidant conditions, two GSH molecules donate one electron each and are converted into glutathione disulfide (GSSG). The GSH/GSSG molar ratio is consid...
Chromatographic determination of glutathione disulfide (GSSG) without any preliminary reduction has been presented using GSSG derivatization by p-hydroxymercuribenzoate (pHMB) in strong alkaline medium followed by the determination of GS–pHMB complex by reversed phase chromatography coupled to ...
The disruption of redox state homeostasis, the overexpression of lipogenic transcription factors and enzymes, and the increase in lipogenic precursors induced by sweetened beverages are determinants of the development of nonalcoholic fatty liver disease.This study evaluated the action of nicotin...
A sensitive and selective sensor for oxidized glutathione (GSSG) detection based on the recovered fluorescence of naphthalimide-DPA (NDPA)-Fe3O4@SiO2-Cu(II) system is reported. NDPA-Fe3O4@SiO2 was characterized by X-ray power diffraction (XRD), transmission electron microscopy (TEM), Fourier tra...
