Ethyl glucuronide in plant extracts :O16

Introduction: The specificity of ethyl glucuronide (EtG) in hair as marker of alcohol consumption exceeds by far those of fatty acid ethyl esters. False positive cases are therefore very rare but not excluded as recent publications have shown. Especially, the use of plant extracts containing high percentages of ethanol can lead to EtG hair concentrations typically found in cases of chronic alcohol consumption. As proposed by Baumgartner et al., a nucleohilic substitution could most likely explain this phenomenon. Fresh and dried plants as well as commercial hair lotions based on plants extracts have been analysed for EtG presence or EtG formation. Methods: Urtica dioica, Plantago lanceolata, Cortex Quercus, Sempervivum, Armoracia rusticana, Juniperus communis, Brassica alba, Thymian vulgaris, Salvia officinalis, Majorana hortensis, Aloe vera, birch gingko and green tea leafs, ginger, lemon grass were extracted in water, water/ethanol (50/50) and ethanol (100%). The extracts as well as diluted hair lotions were measured by immunological test (Microgenics DRI® EtG assay) and by LC-MS/MS on Shimadzu Nexera UHPLC coupled with an AB Sciex 4500 QTrap. Results: EtG could not be detected in water extracts of all tested plants. However, DRI® EtG assay indicated the presence of EtG in 66% of the tested ethanolic plant extracts. That could only be confirmed by mass spectrometry in the cases of fresh thyme as well as in dried birch, oak and plantain extracts where EtG concentrations between of 0.25 and 2,09 mg/l were measured. In one hair lotion, the EtG concentration was 0,76 mg/l. Conclusion: Ethanolic plant extracts represents a non-negligible risk for false positive EtG hair tests, especially when applied as lotion without following washing out. The use of hair care products must therefore be evaluated at every hair sampling. In case of doubt, the product should be analysed by mass spectrometric methods since the presence of EtG can't be proven by use of the DRI® EtG assay, only. Our results support Baumgartner's assumption of a nucleophilic substitution in presence of ethanol because EtG was only measured in the ethanolic extracts.

Complexometric titration with potenciometric indicator to determination of calcium and magnesium in soil extracts¹

This study proposes a method of direct and simultaneous determination of the amount of Ca2+ and Mg2+ present in soil extracts using a Calcium Ion-Selective Electrode and by Complexometric Titration (ISE-CT). The results were compared to those obtained by conventional analytical techniques of Complexometric Titration (CT) and Flame Atomic Absorption Spectrometry (FAAS). There were no significant differences in the determination of Ca2+ and Mg2+ in comparison with CT and FAAS, at a 95 % confidence level. Additionally, results of this method were more precise and accurate than of the Interlaboratorial Control (IC).

Comparison of three antigenic extracts of Eurotium amstelodami in serological diagnosis of farmer's lung disease.

In France and Finland, farmer's lung disease (FLD), a hypersensitivity pneumonitis common in agricultural areas, is mainly caused by Eurotium species. The presence of antibodies in patients' serum is an important criterion for diagnosis. Our study aimed to improve the serological diagnosis of FLD by using common fungal particles that pollute the farm environment as antigens. Fungal particles of the Eurotium species were observed in handled hay. A strain of Eurotium amstelodami was grown in vitro using selected culture media; and antigen extracts from sexual (ascospores), asexual (conidia), and vegetative (hyphae) forms were made. Antigens were tested by enzyme-linked immunosorbent assay (ELISA), which was used to test for immunoglobulin G antibodies from the sera of 17 FLD patients, 40 healthy exposed farmers, and 20 nonexposed controls. The antigens were compared by receiver operating characteristic analysis, and a threshold was then established. The ascospores contained in asci enclosed within cleistothecia were present in 38% of the hay blades observed; conidial heads of aspergillus were less prevalent. The same protocol was followed to make the three antigen extracts. A comparison of the results for FLD patients and exposed controls showed the area under the curve to be 0.850 for the ascospore antigen, 0.731 for the conidia, and 0.690 for the hyphae. The cutoffs that we determined, with the standard deviation for measures being taken into account, showed 67% for sensitivity and 92% for specificity with the ascospore antigen. In conclusion, the serological diagnosis of FLD by ELISA was improved by the adjunction of ascospore antigen.

Philo of Alexandria's De opificio mundi (LIII-LXI): discovering the essential features of Greek and Western Misogyny in a Platonising Jewish Text

The aim of this article is to show the Western centuries-old misogynist tradition from its origins in Greece by analysing a text by the allegorical interpreter of the Bible Philo of Alexandria, his De opifico mundi, which on many occasions is read by him from a Platonic point of view. The accurate analysis of the chapters devoted to the creation of the woman by God proves to what extent it is not possible to understand this text if one does not take into account a Greek philosophical tradition which was already centuries-old.

Antihelenismo y anticlasicismo en la obra de Oscar Wilde. El polo opuesto de una mente paradójica.

Gracias a una poderosa arma intelectual, la paradoja, Oscar Wilde descubre también los déficits del Clasicismo y del Helenismo. Un análisis riguroso del conjunto de su obra desde la perspectiva de la Tradición Clásica, nos revela también un Oscar Wilde diferente del usual Wilde filohelénico y, sobre todo, platónico. El objetivo de este artículo es abordar un tema muy poco estudiado por los filólogos clásicos cual es el anticlasicismo y el antihelenismo como necesidades intelectuales.

Antihel·lenisme i anticlassicisme en l'obra d'Oscar Wilde. L'altre pol d'una ment paradoxal.

Gràcies a una poderosa arma intel·lectual, la paradoxa, Oscar Wilde descobreix tambè els dèficits del Classicisme i l'Hel·lenisme. Una anàlisi acurada del conjunt de les seves obres des de la perspectiva de la Tradició Clàssica, ens revela també un Oscar Wilde diferent de l'usual Wilde filohel·lènic i, sobretot, platònic. L'objectiu d'aquest article és abordar un tema molt poc estudiat pels filòlegs clàssics, l'anticlassicisme i l'antihel·lenisme com a necessitats intel·lectuals

Anti-Hellenism and Anti-Classicism in Oscar Wilde's Works. The Second Pole of a Paradoxical Mind.

Thanks to a powerful intellectual weapon, paradox, Oscar Wilde also discovers the dark side of both Classicism and Hellenism. An accurate analysis of his works from the point of view of the Classical Tradition shows an Oscar Wilde who is quite different from the usual Philhellenic one and, above all, from the Platonic one. The aim of this article is to approach a theme which has been hardly studied by classical philologists, that is, anti-classicism and anti-hellenism as an intellectual urge.

Tennessee Williams's Cat on a hot tin roof or the dramatic aptitudes of the goddess Diana

The aim of this article is to show which are the dramatic "yields" of the inclusion of the reference to the goddess Diana in Tennessee Williams's Cat on a Hot tin Roof. In the author's opinion, it does not deal simply with a meaningful reference; on the contrary, the accurate analysis of Williams's text proves that it is a true nuclear and cohesive element of the whole drama.

Woody Allen and the Spirit of the Greek Tragedy: from Crimes and Misdemeanors to Match Point

Many studies have already paid attention to what is called the "serious films" by Woody Allen and, among them, it is also worth mentioning the one written by the very Pau Gilabert Barberà (2006), which is devoted to the Sophistic legacy underlying in his opinion the screenplay of Crimes and Misdemeanors. On this occasion, his aim is to analyse the fluctuating sight of the American director with regard to the Greek tragedy. Indeed, Gilabert is convinced that, only in this way, it is possible to reveal the true Allen¿s sympathy with the tragic spirit of the Greeks, as well as to understand his urge to present that ancient literary genre as a paradigm with the help of which one can evaluate the greatness and misery of our contemporary world.

Poison without antidote for the historical Socrates and french classical tragedy in El verí del teatre (The Poison of the Theatre) by Rodolf Sirera. (An extreme dose of sadism to put a stop to the excesses of theatrical fiction).

Socrates' serene attitude before his death -although this is questioned-, as described by Xenophon in his Apologia Socratis becomes for the playwright Rodolf Sirera a useful reference in an effort to reflect boldly on the limits of theatrical fiction in another clear example of the Classical Tradition, including that derived from Baroque Tragedy. However, in this case, it is judged severely to make us more conscious of the risk of turning life into a mere theatrical performance and human beings into actors and actresses in a play they did not write.

Verí sense antídot per al Sòcrates històric i la tragèdia barroca al Verí del teatre de Rodolf Sirera. (Una dosi extrema de sadisme per aturar els excessos de la ficció teatral).
