L'Informatione del pestifero et contagioso morbo ... nella visione storica ed etica.

2012

Il saggio introduttivo all'opera di G. F. Ingrassia sulla peste di Palermo del 1575 si propone di analizzare il rapporto medico paziente di quella epoca, le credenze sulle modalità del contagio della peste, le concezioni di bene e di male, le nuove conoscenze sulla astronomia. Il clima di terrore per la presenza dell'Inquisizione sollecita una riflessione, tutt'ora attuale sui rapporti tra medicina e religione. Ma la presenza del protomedico nella Deputazione della città e il contatto con i governanti ha sollecitato una riflessione su medicina e politica. La peste ha portato tanta paura, la nuova padrona dei tempi attuali per l'esercizio medico. Il saggio si chiude con una riflessione sull'…

Contribution à l’étude de la fraction insaponifiable de trois huiles d’olive issues des variétés Guasto, Rougette et Blanquette plantés dans l’est al…

2010

The sterol profile of three Algerian virgin olive oils produced from Guasto, Blanquette and Rougette cultivar’s, varieties grown in the East of the country, was established by gas chromatography using a flame ionization detector and coupled to mass spectrometry. Four sterol compounds were identified and characterized in the three oils which are, sitosterol always predominant (43-66%), delta 5-avenasterol (8-13%), stigmasterol (≤ 1,5%) and campesterol (1-2%); one methyl sterol (4-methylsterol) : citrostadienol (4-7%) and two triterpenic alcohols : 24-methylene cycloartanol (10-33%) and cycloartenol (3-13%). These results vary according to campany and variety. Our study shows that most of the…

Sterol Composition in Infant Formulas and Estimated Intake.

2015

Sterol contents in infant formulas (IFs) from the European market were determined, and their intakes by infants between 0 and 6 months were evaluated. Total animal sterols (mg/100 mL) ranged from 1.71 to 5.46, cholesterol being the main animal sterol (1.46-5.1). In general, cholesterol and desmosterol were lower than the human milk (HM) values indicated by other authors. Total plant sterol (mg/100 mL) ranged from 3.1 to 5.0. β-Sitosterol, the most abundant phytosterol, ranged from 1.82 to 3.01, followed by campesterol (0.72-1.15), stigmasterol (0.27-0.53), and brassicasterol (0.14-0.28). Cholesterol intake (mg/day) ranged from 9 to 51 and plant sterol intake (mg/day) from 19 to 50. The ster…

Identification of bound alcohols in soil humic acids by gas chromatography-mass spectrometry

2000

International audience; Humic acids are complex, partly macromolecular, yellow-brownish substances occurring in soils, waters and sediments. In order to shed some light on their molecular structure, crop humic acids were cleaved by alkaline hydrolysis (KOH). The products were fractionated by thin layer chromatography to give mono-alcohols which were analysed as acetate derivatives by gas chromatography coupled to mass spectrometry. Linear alcohols, sterols, stanols and plant-derived triterpenoid alcohols were identified by co-injection of pure standards and by comparison with literature data. These findings imply that alcohols could have been incorporated into the humic matrix by esterifica…

Sterol oxidation in ready-to-eat infant foods during storage.

2008

The effect of storage on sterol oxidation of ready-to-eat infant foods was evaluated. Two different flavor (honey -LH- or fruits-LF-) liquid infant foods, prepared with milk and cereals, were stored for 0, 2, 4, 7 and 9 months, at 25ºC. Sterol oxidation products (SOP) were extracted by cold saponification, purified by silica solid-phase and analyzed by gas chromatography (GC) and GC-mass spectrometry. -sitosterol was the most representative sterol, followed by cholesterol and campesterol. No significant differences in the total and single SOP content (0.8-1 mg/kg of product) were observed with respect to storage time and type of sample; the main SOP found was 7-ketositosterol (< …

Tocopherol, fatty acid and phytosterol content in seeds of nine wild taxa of Sicilian Brassica (Cruciferae)

2010

The purpose of this study was to determine tocopherol (Toc), fatty acid and phytosterol content in dry seeds of nine wild taxa of Sicilian Brassica sect. Brassica. Analyses were performed by gas chromatography (GC)-mass spectroscopy (MS). The biochemical analysis of dry seeds showed that in the nine taxa examined, α - and γ -Toc were the major isomers, δ - Toc was present in traces and β -Toc was never found. All taxa had a similar fatty acid composition with C 16:0 (357.2 mg kg − 1 DW), C 18:1 (393.94 mg kg − 1 DW) and C 22:1 (618.29 mg kg − 1 DW) acids present in higher amount. Unsaturated fatty acids (52.5–66.5%) were more abundant than saturated (33.5–47.5%) ones relative to the total f…

Isomotiol, a new triterpene from strychnos potatorum

1978

Isomotiol (fern-8-en-3β-ol) was isolated from the leaves of Strychnos potatorum; it was not known previously as a natural product, but it has been obtained by acidic isomerization of compounds with a fern-7-ene or a fern-9(11)-ene skeleton. From the leaves and the bark mixtures of sitosterol, stigmasterol and campesterol were also isolated.

Sterol stability in functional fruit beverages enriched with different plant sterol sources

2012

Abstract Two different plant sterol (PS) sources (free PS from tall oil and esterified PS from vegetable oils) were used for manufacturing two types of functional beverages (fruit and milk-based fruit beverages), and their PS and phytosterol oxidation product (POP) contents were determined. Gas chromatography–tandem mass spectrometry (GC–MS/MS) was used for identification and gas chromatography–flame ionization detection (GC–FID) for quantitation purposes. Brassicasterol, campesterol, campestanol, stigmasterol, β-sitosterol and sitostanol were the quantified PS, conforming a profile in order with current legislation. The relative percentages of PS differed according to the enrichment source…

L'exclusion au Moyen Age

2007

1 article en italien, 1 article en castillan traductions en français; Dans ces actes du colloque organisé par le Centre d'Histoire médiévale de l'Université Jean Moulin - Lyon 3, en mai 2005, se trouvent exposées les principales causes de l'exclusion sociale et politique au Moyen Age. Hormis l'hérésie qui n'est pas le sujet de ce colloque, les motifs d'exclusion sont en effet nombreux : mépris des ethnies réprouvées, dégoût ou crainte de la maladie, rejet de la vieillesse, condamnation de la sexualité, ostracisme politique. Les communications insistent sur les méthodes et les marques de l'exclusion : signes distinctifs, ségrégation, relégation, expulsion, injures, recours aux exceptions jur…
