Cytoprotection assessment against mycotoxins on HepG2 cells by extracts from Allium sativum L

2021

Abstract Cytoprotection effects of Allium sativum L garlic extract from a local garlic ecotype from Ferrara (Italy) on hepatocarcinoma cells, HepG2 cells, is presented in this study. This garlic type is known as Voghiera garlic and has been characterized as PDO (Protected designation of Origin) product. Voghiera garlic extract (VGE) was evaluated against beauvericin (BEA) and two zearalenone (ZEA) metabolites (α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL))-induced cytotoxicity on HepG2 cells by the MTT (3–4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay, over 24 h and 48 h. Direct treatment, simultaneous treatment and pre-treatment strategies at the dilution 1:16–1:00 for VG…

Estrategia medioambiental de la empresa y rendimiento. El rol intermedio del aprendizaje organizativo: Un aplicación a las industrias minerales.

2004

Uno de los temas más polémicos relacionados con la incorporación a la gestión empresarial del condicionante medioambiental es su impacto en el rendimiento. Mientras unos defienden la existencia de estrategias win-win gana la empresa, gana el medio ambiente , otros anuncian que no es fácil ser verdes. Para buscar una explicación a este pensamiento dispar, consideramos la posible existencia de una o más variables intermedias que pudieran moderar incluso modificar esta relación.Los trabajos relacionados con el aprendizaje organizativo hacen atribuciones casi milagrosas a las learning oganizations. Estas organizaciones son poseedoras de una ventaja competitiva sostenible en el tiempo: la capaci…

A Theoretical Study of the Favorskii Rearrangement. Calculation of Gas-Phase Reaction Paths and Solvation Effects on the Molecular Mechanism for the …

1997

The molecular mechanism of the α-chlorocyclobutanone transposition to yield cyclopropanecarboxylic acid, as a model of the Favorskii rearrangement, has been theoretically characterized in vacuo by means of ab initio molecular orbital procedures at the Hartree−Fock (HF) level of theory with the 6-31G* and 6-31+G* basis sets. The electron correlation has been estimated at the MP2/6-31G* level and calculations based on density functional theory, BLYP/6-31G*. The solvent effects are included at HF/6-31G* level by means of a polarizable continuum model. The questions related to the two accepted molecular mechanisms, the semibenzilic acid and the cyclopropanone transpositions, as well as the comp…

Partielle spezifische refraktionen von polymethylmethacrylat und polystyrol. I. Einfluß verschiedener lösungsmittel

1969

Auf der Grundlage der Formeln von LORENTZ-LORENZ, GLADSTONE-DALE und EYKMAN wurden die partiellen spezifischen Refraktionen von Polymethylmethacrylat in den Losungsmitteln Aceton, Athylacetat, Butylacetat, Tetrahydrofuran, Dioxan, Chloroform, Toluol und Benzol sowie die von Polystyrol in Butanon, Dioxan, Toluol und Benzol bestimmt. Es zeigt sich, das these Werte, die mit einer Genauigkeit von ± 0,1% aus den experimentellen Grosen Brechungsindex-Inkrement, Brechungsindex der Losung und partielles spezifisches Volumen berechnet wurden, nicht ganz frei von Losungsmitteleinflussen sind. Der groste Unterschied wurde bei den LORENTZ-LORENZ-Refraktionen gefunden und betrug 1,3%. Die EYKMAN-Refrakt…
