Tumor contamination of autologous peripheral blood stem/progenitor cell grafts occurs in a substantial proportion of high-risk breast cancer patients, and the possibility that such contamination may contribute to relapse has focused attention on methods for removal of the contaminating cells prior to transplantation. One such approach is positive selection(More)
Authentication of a food product is the procedure by which it is verified that the product matches the statements on the label, and that it conforms to what is established by regulations. This testing process includes analysis of the ingredients, determination of the geographical origin, and examination of the production methods. In particular, the use of(More)
A fast and reliable HPLC method for the determination of 11 biogenic amines in beverages has been performed. After pre-column derivatization with dansyl-chloride a Kinetex C18 core-shell particle column (100 mm × 4.6 mm, 2.6 μm particle size) has been employed and the biogenic amines were identified and quantified in a total run time of 13 min with(More)
Thirty patients (18 women, 12 men) with permanent or paroxysmal atrial fibrillation were treated with a new antiplatelet drug, ticlopidine, in order to study platelet aggregation behaviour, to see whether the drug prevents thromboembolisms and to observe side-effects over a period of 6 months. A further comparative study of the effects of ticlopidine and(More)
Liquid-liquid microextraction coupled to LC with fluorescence detection for the determination of Environmental Protection Agency's 16 priority pollutant polycyclic aromatic hydrocarbons in rainwater has been developed. The optimization of the extraction method has involved several parameters, including the comparison between an ultrasonic bath and a(More)
The increased separation efficiency provided by the new technology of column packed with core-shell particles in high-performance liquid chromatography (HPLC) has resulted in their widespread diffusion in several analytical fields: from pharmaceutical, biological, environmental, and toxicological. The present paper presents their most recent applications in(More)
Right ventricular infarction in inferior left ventricular infarction is very common. We have examined, by means of equilibrium gated radionuclide angiography, the relationship existing between right ventricular infarction and atrioventricular block. Seventy-two patients with inferior wall myocardial infarction were studied. Thirty-nine of them had(More)
