Abstract:
Abstract Traditional diagnosis of hemoglobinopathies rely on separation and accurate quantification of hemoglobin (Hb) fractions using alkaline and acid electrophoresis, isoelectric focusing (IEF) and/or High Performance Liquid Chromatography (HPLC). Recent reports have suggested capillary electrophoresis (CE) as an alternate method for screening. We evaluated a new CE system the Sebia CapillaryS 2 (Evry Cedex, France) and compared it to IEF and HPLC. For this evaluation samples referred to our laboratory for routine hemoglobinopathy screening or as cord bloods sent for confirmation of a varia

Abstract:
An HPLC-UV fingerprint analysis was developed for the quality evaluation of Andrographis paniculata aerial parts. HPLC-DAD-MS experiments allowed the identification of eleven diterpenes and five flavonoids. Plant material of Indian and Chinese origin was evaluated employing the developed method. The chemical fingerprints of the plant material of different origins do not show significant differences.

Abstract:
Abstract The determination of PAH metabolites in fish bile is performed to assess the PAH contamination in fish for environmental monitoring. A growing number of laboratories in Europe use this parameter for national monitoring. However, an international intercomparison between laboratories has not taken place in the last years. Therefore the determination of the PAH metabolite 1-hydroxypyrene was tested in a collaborative trial performed by 10 laboratories from eight countries. Five samples of naturally contaminated fish bile covering different concentration levels were distributed among the

Abstract:
Abstract Hemoglobin A2 (Hb A2) and hemoglobin F (Hb F) are important analytes in the diagnosis and follow up of Hb diseases. We evaluated a new capillary zone electrophoresis (CZE) kit for Hb A2 and Hb F measurements. The imprecision ranged from 3% to 6% for Hb A2 and Hb F at physiological and pathological concentrations. The method compared well with cation-exchange HPLC for Hb A2 and Hb F and with anion-exchange chromatography in microcolumns (MAEC), for Hb A2. Nevertheless, higher results were obtained [Hb A2 CZE (%) = 1.233 Hb A2 HPLC − 0.2; Hb A2 CZE (%) = 1.190 Hb A2 MAEC + 0.1; Hb FCZE

Abstract Background: Information on interlaboratory variation and especially on methodological differences for plasma total homocysteine is lacking. Methods: We studied 14 laboratories that used eight different method types: HPLC with electrochemical detection (HPLC-ED); HPLC with fluorescence detection (HPLC-FD) further subdivided by type of reducing/derivatizing agent; gas chromatography/mass spectrometry (GC/MS); enzyme immunoassay (EIA); and fluorescence polarization immunoassay (FPIA). Three of these laboratories used two methods. The laboratories participated in a 2-day analysis of 46 pl

O Brasil é o maior produtor mundial do maracujá, e em vista disto é de suma importância o desenvolvimento de métodos analíticos e estudos de atividade antioxidante e anti-inflamatória do fruto de maracujá, visando sua possível utilização como alimento funcional e produção de possíveis fármacos.
