Determination of Pesticide Residues in Honey by Single-Drop Microextraction and Gas Chromatography
(2011)A novel, simple, and rapid single-drop microextraction (SOME) procedure combined with GC has been developed, validated, and applied for the determination of multiclass pesticide residues in honey samples. The SDME was ... -
Direct ethanol PEM fuel cells: The case of platinum based anodes
(2005)PtSn/C catalysts were prepared by the direct decoration of Pt/C with Sn through a modified poly process. XRD results showed there existed obvious SnO2 in this catalyst, different from the PtSn/C prepared by co-precipitation, ... -
The effect of the MEA preparation procedure on both ethanol crossover and DEFC performance
(2005)In the present work, the changes of Nafion((R))-115 membrane porosity in the presence of ethanol aqueous solutions of different concentrations were determined by weighing vacuum-dried and ethanol solution-equilibrated ... -
Elimination profiles of flurbiprofen and its metabolites in equine urine for doping analysis
(2001)Flurbiprofen and its main acidic metabolites were detected in equine urine after a single-dose administration of 500 mg flurbiprofen to two 2.5-3.5-years-old mares, in order to be used in equine doping control routine ... -
Evaluation and Properties of the Budding Yeast Phosphoproteome
(2012)We have assembled a reliable phosphoproteomic data set for budding yeast Saccharomyces cerevisiae and have investigated its properties. Twelve publicly available phosphoproteome data sets were triaged to obtain a subset ... -
High-performance liquid chromatographic determination of benzoylurea insecticides residues in grapes and wine using liquid and solid-phase extraction
(1999)A method for the determination of the benzoylurea insecticides diflubenzuron, triflumuron, teflubenzuron, lufenuron and flufenoxuron in grapes and wine by HPLC has been developed and validated. Grape samples (50 g) were ... -
Impact of biological factors on binding media identification in art objects: Identification of animal glue in the presence of Aspergillus niger
(2004)The materials and especially organic materials used for creation of art objects can be utilized by various microorganisms for their growth and facilitate the microbial colonization of the object. An understanding of the ... -
In vivo evaluation of CYP1A2 CYP2A6, NAT-2 and xanthine oxidase activities in a Greek population sample by the RP-HPLC monitoring of caffeine metabolic ratios
(2007)A RP-HPLC method was developed for the assessment of caffeine and its metabolites in urine and was used for the evaluation of the CYP1A2, CYP2A6, xanthine oxidase (XO) and N-acetyl-transferase-2 (NAT-2) in vivo activities ... -
Interplay between protein carbonylation and nitrosylation in plants
(2013)ROS and reactive nitrogen species (RNS) are key regulators of redox homeostasis in living organisms including plants. As control of redox homeostasis plays a central function in plant biology, redox proteomics could help ... -
Liquid chromatographic determination of fosthiazate residues in environmental samples and application of the method to a fosthiazate field dissipation study
(2005)A method was developed and validated for the determination of residues of the organophosphorus nematicide fosthiazate in soil and water by using reversed-phase liquid chromatography with UV detection. Good recoveries (> ... -
Microwave-assisted Extraction of Glucosinolates from Eruca sativa Seeds and Soil: Comparison with Existing Methods
(2009)Introduction - Glucosinolates (GSLs) are secondary plant metabolites that are abundant in brassicas and their hydrolysis products, isothiocyanates, are toxic to soil pathogens. Efficiency and extraction time are critical ... -
Migration Phenomenon in Food Packaging. Food-Package Interactions, Mechanisms, Types of Migrants, Testing and Relative Legislation-A Review
(2014)The development of convenient and low-cost packages, together with the increased consumer demands for safer products, have resulted in the conduction of extensive research and the publication of numerous studies related ... -
Modeling of signaling pathways in chondrocytes based on phosphoproteomic and cytokine release data
(2014)Objective: Chondrocyte signaling is widely identified as a key component in cartilage homeostasis. Dysregulations of the signaling processes in chondrocytes often result in degenerative diseases of the tissue. Traditionally, ... -
