Effect of oral glutathione on hepatic glutathione levels in rats and mice
Administration of oral glutathione (GSH) increases hepatic GSH levels in fasted rats, in mice treated with GSH depletors such as diethyl maleate and in mice treated with high doses of paracetamol. An increase in hepatic GSH levels after administration of oral GSH does not occur in animals treated with buthionine sulphoximine, an inhibitor of GSH synthesis. Administration of oral GSH leads to an increase in the concentration of l-cysteine, a precursor of GSH, in portal blood plasma. Oral administration of l-methionine produced a significant decrease of hepatic ATP in fasted rats, but not in fed rats. Administration ofN−acetylcysteine or GSH did not affect the hepatic ATP levels. The results …
What drives the helpfulness of online reviews? A deep learning study of sentiment analysis, pictorial content and reviewer expertise for mature destinations
Los destinos turísticos se ven cada vez más afectados por la información relacionada con los viajes que se comparte a través de las redes sociales. Basándose en teorías de proceso dual sobre cómo los individuos procesan la información, este estudio examina el papel de las rutas de procesamiento de información central y periférica en la formación de las percepciones de los consumidores sobre la utilidad de las reseñas en línea de destinos maduros.

Buying private label in durables: Gender and other psychological variables
Abstract In the context of durables, this paper analyzes some key psychological variables identified in convenience goods literature, for individuals facing private label purchase decisions: private label attitude, price consciousness, brand consciousness and involvement with the product. The role of gender in the relationships among those variables is also examined. On two different durables and with a sample of 432 individuals, all the proposed relationships are significant, except for price consciousness. Additionally, some gender differences among those relationships appear. Data suggest that being a woman (not a man) plays a key role in private label purchase intention.
Do Men and Women Differ When Purchasing Private Label Goods?

On a sample of 433 individuals, and considering two different shopping goods, results showed differences between men and women in all the variables, except in the value consciousness. Furthermore, due to a multigroup analysis technique, we found more differences between the variables affecting PL purchase intention. Acc…
Understanding University Library Users' Mistreatment of Books
This paper analyses university library users' attitudes towards book vandalism in order to develop a basis for intervention. Using a customer oriented approach data was collected from users who attended an academic library exhibition on vandalized books at a University campus. Respondants were asked both for their reactions to the vandalism as well as to suggest measures to solve this problem. Punishment and surveillance were most frequently mentioned as preventative measures although users also recognized the utility of the exhibition in increasing awareness of book mutilation. Further implications of social marketing for libraries are also discussed.
