Background: Doxorubicin (Dox) is a medicine for cancer chemotherapy in various cancers, such as leukaemia, lympyoma and breast cancer. However, the Dox metabolite induced cardiotoxicity. Therefore, how to monitor exactly the concentration of Dox and its metabolites in plasma or serum is an important issue. Methods: Doxorubicin was dissolved in ethanol to prepare 10000 μg/mL solutions. Doxorubicin solution (20 Read More

Background: Concerns has been raised for developing flexible, lightweight, sustainable and environmental friendly energy storage and conversion device to meet the energy demand of the modern society. In the recent past, supercapacitors have gathered much attention as a promising electrochemical energy storage system because of its high power density, excellent cycle life and rapid chargedischarge. The key eleme Read More

Background: Antimony is a metaloide that offers human health risks. Then, the determination of this chemical element in food samples is always opportune. This paper proposes a method for determination of total antimony in fish muscle tissue using hydride generation atomic absorption spectrometry (HG AAS). Methods: The optimization of the quantification step was performed using a two-level full factorial design and a Read More

Background: This study describes a simple and rapid analytical method for the simultaneous determination of trace amounts of copper(II), zinc(II), nickel(II), cobalt(II), iron(II), cadmium(II) and mercury(II) in fish samples by the reversed-phase highperformance liquid chromatography (RP-HPLC) with di-2-pyridyl ketone benzoylhydrazone (DPKBH) as pre-column derivatization reagent. Methods: Seven metal chelates were successf Read More

Background: Hawthorn species (Crataegus) belonging to the Rosaceae family is one of the most commonly used phytopharmaceuticals against mild cardiovascular diseases. The use of medicinal herbs is regulated by the World Health Organisation regarding their content of toxic elements. Thus it is important to study the elemental pattern of the plant organs used to ensure safe use on the one hand and sufficient amounts of essen Read More

Introduction: The growing textile industry has posed a prudent threat to already depleting freshwater resources. Therefore, it is essential to treat dyes from effluents prior to their discharge using some low-cost adsorbents in the scenario of developing countries like Pakistan. Objectives: The current manuscript deals with the screening of agriculture and forest waste adsorbents for removal of hazardous malachite green (MG) Read More

Objective: A comprehensive monosaccharide quantifying method was developed in this article. Monosaccharides (including glucose, arabinose, galacturonic acid, galactose, mannose, rhamnose and xylose) were analyzed by RP-HPLC-DAD method. Meanwhile, mannitol and fructose were calculated based on peak areas obtained by HPIEC-RID and corresponding data obtained by RP-HPLC-DAD. Monosaccharide composition Read More

Background: Quantitative structure-mobility relationships are proposed to estimate the electrophoretic mobility of diverse sets of analytes in capillary zone electrophoresis using Abraham solvation parameters of analytes, namely the excess molar refraction, polarizability, hydrogen bond acidity, basicity, and molar volume. Multiple linear regression (MLR) as a linear model, adaptive neuro-fuzzy inference system (ANFIS), a Read More

Background: The solution scannometric technique was introduced recently by Abbaspour et al. They used commercially available flatbed-scanners for obtaining the images of color solutions. The obtained images have been transferred to computer for analyzing and determining the intensity of color solutions. The method is based scanning of solution phase, in Plexiglas® cells. Finally the RGB (red, green and blue) color model w Read More
