BACKGROUND Patients with Fabry disease (FD) show left ventricular hypertrophy (LVH) mimicking hypertrophic cardiomyopathy (HCM) of sarcomeric origin and might benefit, if detected early, from specific enzyme replacement therapy. The prevalence of FD in patients with LVH of 13 mm or greater, screened using the leucocyte alpha-galactosidase A (α-gal A)(More)
A simple, rapid method for the simultaneous determination of cardiovascular drugs: celiprolol, bisoprolol and irbesartan in human plasma is described. The two main features of the proposed method deal first, with a simultaneous solid phase extraction of weakly basic beta-blockers derivatives and irbesartan which exhibit weak acidic properties; second with(More)
Due to its high sensitivity and specificity, determination of the c-galactosidase A activity in leukocytes is the gold standard to confirm the diagnosis of Fabry disease in hemizygous moles. In contrast, heterozygous females cannot be dependably diagnosed by this method and genotyping should always be carried out. Two recent breakthroughs have contributed(More)
INTRODUCTION Fabry disease (FD) is an X-linked lysosomal storage disorder caused by mutations in the GLA gene, which leads to a deficient activity of α-galactosidase A. α-galactosidase A activity can be assayed on dried blood spots on filter paper but the original method has been associated with a number of false positive due in great part to quenching of(More)
1,6-Diphenyl-1,3,5-hexatriene (DPH) is the most widely proposed molecular probe for the post-column fluorescence derivatization of lipids after liquid chromatography separation. This kind of detection consists of a supramolecular combination of DPH and eluted lipids. The detection is optimally performed in a mainly aqueous environment (over 80% v/v) because(More)
A general approach, still few exploited so far and never associated with microbore-LC, consisting of detection of various lipid classes (i.e. phospholipids, triglycerides, ceramides and glycosphingolipids) by non-covalent association with 1,6-diphenyl-1,3,5-hexatriene (DPH) fluorescence probe is developed. This mode of detection was coupled with non-aqueous(More)
PURPOSE To minimize the risk of chronic occupational exposure of antineoplastic drugs, cleaning procedures must be evaluated. This study was conducted to compare the detergent efficiency of cleaning solutions (two hydro-alcoholic solutions, three disinfectants and two detergents) used in different cleaning protocols. METHODS The central surface of a(More)
Raman microspectroscopy has been shown to enable the identification of micro-particles inside sealed glass containers for pharmaceutical use without any sample preparation. Raman spectra were collected from unknown particles with a maximum size of 1mm, adsorbed on the inner surface of ampoules. The particles were clearly identified as primarily hematite(More)
A simple and sensitive method is described for the determination of platinum surface contamination originating from cisplatin, carboplatin and oxaliplatin. Following extraction from swabs and preconcentration with the cloud point extraction (CPE) method, detection was by graphite furnace atomic absorption spectrometry (GFAAS). After desorption of platinum(More)
Phospholipids are essential constituents of all living cell membranes. There are many analytical methods available for the quantitative and qualitative determination of phospholipids, but since these molecules lack chromophores, common absorbance based methods are of limited use. Beside mass spectrometry, some less specific approaches that are routinely(More)
