Voltammetric Method for Simultaneous Determination of L-Dopa and Benserazide

06-Jun-2017 | Alexandra Rabinca, Andreea; Buleandra, Mihaela; Tache, Florentin; Mihailciuc, Constantin; Magdalena Ciobanu, Adela; ..., Current Analytical Chemistry, 2017

Abstract: Background: The aim of this work was to develop an efficient voltammetric method for rapid analysis and simultaneous determination of L-dopa and benserazide (Bz) in pharmaceutical formulations. To the best of our knowledge simultaneous electrochemical determination of the ...


A Fluorescent Probe Using the Boron and Nitrogen Co-Doped Carbon Dots for the Detection of Hg2+ Ion in Environmental Water Samples

06-Jun-2017 | Bian, Wei; Wang, Yakun; Yang, Haifen; Li, Ping; Yu, Qing; Shuang, Shaomin; Dong, Chuan; M. F. Choi, Martin, Current Analytical Chemistry, 2017

Abstract: Background: Mercury (Hg2+) ion which is one of the most toxic heavy metals, can pollute the environment and threaten human health due to its features of non-biodegradation and bioaccumulation. Therefore, the detecting of Hg2+ ion is very necessary and has received increasing ...


Au-Nanoparticles Based Sensors for Voltammetric Determination of Glutathione

06-Jun-2017 | O. Perevezentseva, Darya; V. Korshunov, Andrey; V. Gorchakov, Eduard; I. Bimatov, Vladimir; E. Phedorov, Ivan, Current Analytical Chemistry, 2017

Abstract: Background: Glutathione (GSH) is a water-soluble tripeptide which is contained in biological fluids (blood plasma, cell fluid) and plays an important role in redox processes in the organisms of humans and animals. The lack of GSH leads to oxidative stress in living cells and ...


In vivo Distribution of Tiotropium in a Rodent Model Utilizing AP-SMALDI Mass Spectrometry Imaging

06-Jun-2017 | Vegvari, Akos; E. Fehniger, Thomas; Dahlback, Magnus; Marko-Varga, Gyorgy; Strupat, Kerstin, Current Analytical Chemistry, 2017

Abstract: Background: Matrix-assisted laser desorption/ionization mass spectrometry imaging has proved to be a powerful tool in localization of endogenous molecules in thin tissue sections. Distributions of drug compounds following administration in experimental animal models can be ...


Total Antioxidant Capacity and Polyphenol Concentration of Several Pharmaceutical Integrators and Food or Feed Based Vegetables, Measured and Compared Using Two Different Enzyme Sensors

06-Jun-2017 | Tomassetti, Mauro; Angeloni, Riccardo; Martini, Elisabetta; Campanella, Luigi, Current Analytical Chemistry, 2017

Abstract: Background: This research had two purposes: first to verify if two enzyme biosensors developed by our research group for determining the Total antioxidant capacity (TAOC) and to determine the total polyphenol concentration (TPC) could correctly be used even in matrices such as ...


Volatile Organohalogen Compounds Determination with Dispersive Liquid-Liquid Microextraction Applying Solvent Lighter than Water

06-Jun-2017 | Bigus, Paulina; Szalkiewicz, Alicja; Namiesnik, Jacek; Tobiszewski, Marek, Current Analytical Chemistry, 2017

Abstract: Background: Volatile organohalogen compounds (VOX) are a group of environmental pollutants that risk the quality of drinking water. These compounds are characterized by certain acute and chronic toxicities, possessing mutagenic properties. Because of these potential risks factors ...


The Study on the Fingerprint and Qualitative Analysis of Characteristic Volatile Constituens in Xihuang Pill by GC/GC-MS

06-Jun-2017 | Li, Xiaoshi; Zhou, Jie; Kuang, Guojun; Shang, Xueying; Liu, Xiaolin; Tong, Ling; Zhang, Lei, Current Analytical Chemistry, 2017

Abstract: Background: In the modern clinical practice of TCM science, the formula Xihuang pill has been widely used as a remedy for the treatment of various tumors in clinical application. Due to the diversity of the manufacturers and relatively lower quality standards, the quality problem ...


Determination of Cd2+, Cr3+, Cu2+ and Zn2+ in Traditional Chinese Medicine Shuanghuanglian Oral Liquid by High Performance Capillary Electrophoresis

06-Jun-2017 | Luan, Feng; Lu, Yuxi; Tang, Lili; Liu, Huitao, Current Analytical Chemistry, 2017

Abstract: Background: The safety and level of heavy metal ions in the traditional Chinese medicine has become an important topic. Most of the metal ions are carcinogens and lead to serious health concerns by producing free radicals. It is of great significance to develop simple and ...


HPLC Fingerprints for the Authentication of Cranberry-Based Products Based on Multivariate Calibration Approaches

06-Jun-2017 | Puigventos, Lidia; Nunez, Oscar; Saurina, Javier, Current Analytical Chemistry, 2017

Abstract: Background: Food products and pharmaceuticals prepared with American red cranberries are gaining importance in our society due to some healthy effects on humans. However, some concerns have arisen on the evaluation of authenticity of red cranberry extracts as well as on the ...


Application of Combined Electrochemical Approaches for Removing/ Determining Cr(VI)

06-Jun-2017 | Cristina M. de Moura, Elaine; R. do Vale Souza Gois, Paulo; R. da Silva, Djalma; Medeiros de Araujo, Danyelle; A. Ma ..., Current Analytical Chemistry, 2017

Abstract: Background: In this work, a combined electrochemical approach has been developed for the purification and detection of chromium species in aqueous effluents. With this in mind, the technique of differential pulse voltammetry (DPV) using ultratrace graphite electrode was applied for the ...
