Robustness evaluation of the chromatographic method for the quantitation of lumefantrine using Youden's test

O teste de Youden constitui um método confiável para avaliação da robustez de métodos analíticos, por meio de um delineamento que envolve sete parâmetros analíticos combinados em oito experimentos. No presente estudo, a robustez de um método cromatográfico para quantificação de lumefantrina em matéria-prima farmacêutica foi avaliada utilizando-se o teste de Youden. Assim, foi possível determinar o efeito de cada parâmetro analítico nos resultados finais das análises. O teste de Youden se mostrou um procedimento simples e confiável para a avaliação da robustez de métodos cromatográficos.Youden's test is a reliable method to evaluate the robustness of analytical methods, by means of an experiment design which involves seven analytical parameters combined in eight tests. In the present study, we assessed the robustness of a chromatographic method to quantify lumefantrine in raw material samples, using Youden's test. Hence, it was possible to determine the effect of each analytical parameter in the final analysis results. Youden's test showed to be a simple and feasible procedure to evaluate the robustness of chromatographic methods

Les importations d’amphores Dressel 20 en Gaule Cisalpine

José Remesal Rodríguez examined question of Baetica olive oil imports in Germania and Rome but lacked data on Cisalpine Gaul. This study aims at supplementing the data on import of Baetica olive oil to Northern Italy. As a result of a query in deposits in Friuli and Veneto a map of distribution of amphorae type Dressel 20 on the mainland was established. The image complements data concerning Transpadana and Transalpine Gaul. A map showing finds of Baetica amphorae in the Venetian Lagoon also arose. The lagoons of the Upper Adriatic were used for a transportation of goods to Aquileia, Concordia, Altino, Oderzo, Este and Verona. Dressel 20 amphorae are most numerous in Aquileia. In remaining cities of the Adriatic coast only single pieces of amphorae for olive oil were spotted. Analysis of these amphorae deposits enabled construction of a hypothesis on the existence of microregions in imports of goods to areas of Cisalpine Gaul during the Roman period

Occurrence and expression of virulence-related properties of Vibrio species isolated from widely consumed seadfood products

none5In this study, widely consumed fresh seafood products were examined for the presence of Vibrio spp. Thirteen percent of the samples examined were found to be contaminated with halophilic vibrios belonging to the species V. alginolyticus (81.48%),V. parahaemolyticus(14.8%) andV. choleraenon 0:1 (3.7%). A greater isolation frequency (18.9%) was found for mussels. Significant adhesiveness and strong cytotoxicity factors were revealed in a significant number of theVibriospp. isolated. These results confirm that the presence of Vibrio spp. in seafood products is common, and suggest that routine examination of such products for these pathogenic agents would be advisable.openW.BAFFONE; A.

El papel de la Bahía de Mazarrón (Murcia) en los contactos comerciales mediterráneos en época romana

For many years I have dedicated myself to the study of commercial contacts between the Roman provinces, based on research on amphorae. The knowledge of the production of the amphorae of Baetica and the deposits of the amphorae of Galia Cisalpina made it possible to draw conclusions about commercial contacts between these provinces. The aim of my new study of amphorae from Mazarrón Bay (Murcia), funded by the NCN - National Science Centre in Poland, arose from my previous research. Thanks to the collaboration of the University of Murcia, the Archaeological Museum of Murcia and the Municipal Archaeological Museum of the “Factoría Romana de Salazones” of Mazarrón, I was able to document the hitherto unpublished amphorae of the Mazarrón coast. During the process of documenting 574 amphorae, excavated in the dredging works in Puerto de Mazarrón, in the stores of the Museum of Murcia and the Museum of Mazarrón, I registered 169 containers coming from the production of the south coast of the region of Murcia. The typological and chronological elaboration, as well as the comparison with the finds of amphorae in the interior of the Mazarrón area, allow conclusions to be drawn about the local production and imports of containers from other regions of the Iberian Peninsula and from other Mediterranean areas. The study, based on pieces of material culture, allows the reconstruction of the role of Mazarrón Bay in the ancient trade of the peninsular southeast and other Mediterranean areas

Amphorae in the Exhibition of the Archaeological Museum in Murcia (Spain)

This article deals with ancient amphorae in the exhibition of the Archaeological Museum of Murcia (Spain). So far, the amphorae have only had inventory cards and there has been no typological-chronological study of them. Each of the 8 amphorae is a different type and purpose. These are finds from various locations in the Region of Murcia. The aim of the study is to supplement museum data and to show the Polish reader amphorae of local production and those imported to this region of Spain in the ancient period

Naval crossfire: a comparative analysis of iron projectiles from mid-18th to early 19th centuries European warships

The ordnance of early Modern main maritime powers (i.e. Great Britain, France, and Spain) played an important role in conflictsfor supremacy of the seas. Therefore, it was subjected to various innovation processes, in order to improve their efficiency. Thisstudy presents the characterization results of an array of iron projectiles recovered from the following sites: 1) the sloop-of-warHMS Swift (1763-1770), 2) the Spanish ship Triunfante (1756-1795), 3) the French ship Bucentaure (1804-1805), and 4) the siteDeltebre I (1813). Based on data obtained using Optical Microscopy (OM), Scanning Electron Microscopy (SEM), and EnergyDispersive X-ray Spectrometry (EDXRS), a comparative analysis was performed, in order to clarify the technological differencesand similarities that were present in the projectiles used by the mentioned ships.Fil: Ciarlo, Nicolás Carlos.

Anfore espagnole del depostio di Verona (Italia). Interpretazione dei dati analiticii

We present the study of the amphorae found near the Tomb of Julie in Verona, as part of an investigation that we are carring out on the Baetican amphorae found in the Veneto región (Italy). Generally the Baetican amphorae studied here may be classified as a Dr 7 or 8 of incomplete amphorae Dr 7/8 should be verified.. Petrographical and mineralogical (XR Diffraction) analyses were made on the samples of Baetican amphorae. Usual statical methods, together with a new method called here «lpercubo» were applied for the elaboration of the same quantitative data of mineralogical analyses.. The most useful results were obtained by Discriminant Analysis and the «Ipercubo» method, proving that the majority of incomplete forms Dr 7/8 have pastes similar to the pastes of the Dr 7 group.Presentamos un estudio de las ánforas béticas halladas cerca de la Tumba de Julieta en Verona que forma parte de un trabajo general sobre todas las ánforas béticas procedentes de la región. La mayoría de ellas se clasifican como Dr.7 y 8 (Beltrán IA y B), dudándose a qué tipo pertenecían algunas ánforas incompletas. Para verificarlo se realizaron análisis Petrográficos y mineralógicos (difracción de RX), aplicándose para la elaboración de los datos cuantitativos de estos últimos, además delos normales métodos estadísticos, uno nuevo que denominamos «hipercubo». Los mejores resultados se han obtenido con el método discriminante y el «hipercubo» que muestra cómo las pastas de la mayoría de las ánforas incompletas se asemejan a las del grupo Dr 7

An innovative, simple, fast, and less toxic high-performance liquid chromatographic method for determination of prednisone in capsules

Prednisone is an anti-inflammatory steroid drug widely used in clinical practice. However, no high-performance liquid chromatographic (HPLC) method has been described in the literature for the determination of prednisone in capsules until now. Thus, an HPLC method was developed using a C18 (250x4.0, 5 µm) column, with methanol:water (70:30) as mobile phase at a flow rate of 1 mL/min and detection at 240 nm. The developed method was validated following current Brazilian legislation. Additionally, linearity was assessed by evaluating the assumptions of normality, homoscedasticity, and independency of residuals, and the fit to the linear model. The method showed linearity (r2>;0.99) over the range of 14.0-26.0 µg/mL, selectivity, precision (RS
