Relationship between the acid and limonin content of Washington Navel orange juices
1985
Juice samples of Washington Navel oranges from three groves were analysed for limonin, °Brix and acid during several seasons. A strong correlation between limonin and acid content has been found.

Ferrocenylbis(ylene) phosphoranes
1997
The ferrocenylbis(methylene)phosphorane Fc-P(=CTms 2 ) 2 ( 1 ) (Fc = −C 5 H 4 FeC 5 H 5 ) can be synthesized starting from ferrocenyldichlorophosphane FcPCl 2 or ferrocenyldilithiophosphane FcPLl 2 . The X-ray structure of ( 1 ) shows some unusual structural features, which indicate considerable electronic interaction of the ferrocenyl group and the σ 3 λ 5 -phosphorane unit. As a consequence of this interaction, the rotational barrier of the methylene bonds is extraordinary low. Therefore, in contrast to other bis(methylene)phosphoranes, the endo - and exo -Tms groups are indistinguishable on the NMR time scale even at −100°C. The analogous ferrocenylbis(imino)phosphorane Fc-P(=NTms) 2 ( 9…
Alfred Gotthold Meyer, Canova (Bielefeld-Leipzig, Velhagen & Klasing 1898), introduzione e traduzione in italiano a cura di Alexander Auf der Heyde, …

Translation, comment and introduction to Alfred Gotthold Meyer's illustrated monograph "Canova" (Bielefeld-Leipzig 1898). This edition includes furthermore indexes and a critical catalogue of all graphic and photographical sources used for the autotypes.
Canova divulgato tra «Können» e «Wollen» nell’opera di Alfred Gotthold Meyer
2014
This article is a critical introduction to the Italian translation of Meyer's Canova monograph (1898), it focuses on the editorial process and on the use of photography during this early stage of popular art history. Further consideration is given to Meyer's critical point of view in the context of the German fin-de-siècle art discourse (Burckhardt, Springer, Bode, Wölfflin, Hildebrand).
Comparison of the antibacterial effect of uroepithelial cells from healthy donors and children with asymptomatic bacteriuria
1985
Bacterial attachment to uroepithelial cells (UEC) and the effect of UEC on bacterial growth was investigated in 15 healthy persons and 12 patients suffering from asymptomatic bacteriuria (ABU) with recurrent urinary tract infections (UTI). Desquamated UEC and mannose-resistant Escherichia coli were co-cultivated for up to 90 min. While no difference in bacterial adherence was observed between healthy controls and patients, 33.4% of the bacteria attached to normal UEC were found to be dead under microscopic evaluation (acridine orange staining), whereas no killing effect could be observed in patients' UEC 5 min after the onset of incubation. This phenomenon was confirmed by investigating the…
Seeing odors in color: Cross-modal associations in children and adults from two cultural environments
2018
International audience; We investigated the occurrence and underlying processes of odor–color associations in French and American 6- to 10-year-old children (n = 386) and adults (n = 137). Nine odorants were chosen according to their familiarity to either cultural group. Participants matched each odor with a color, gave hedonic and familiarity judgments, and identified each odor. By 6 years of age, children displayed culture-specific odor–color associations, but age differences were noted in the type of associations. Children and adults in both cultural groups shared common associations and formed associations that were unique to their environment, underscoring the importance of exposure le…
Ultra-Performance Liquid Chromatography-Ion Mobility Separation-Quadruple Time-of-Flight MS (UHPLC-IMS-QTOF MS) Metabolomics for Short-Term Biomarker…
2020
A major problem with dietary assessments is their subjective nature. Untargeted metabolomics and new technologies can shed light on this issue and provide a more complete picture of dietary intake by measuring the profile of metabolites in biological samples. Oranges are one of the most consumed fruits in the world, and therefore one of the most studied for their properties. The aim of this work was the application of untargeted metabolomics approach with the novel combination of ion mobility separation coupled to high resolution mass spectrometry (IMS-HRMS) and study the advantages that this technique can bring to the area of dietary biomarker discovery, with the specific case of biomarker…
Impact of a non-attentively perceived odour on subsequent food choices
2014
International audience; Current research in psychology suggests that unconscious processes influence a significant proportion of choices and decisions. To study the impact of a non-attentively perceived odour on food choices, we used a priming paradigm. We had previously shown that non-attentively perceived fruity odours could impact food choice intentions (on a menu card), guiding participants toward items containing more fruit and/or vegetables. The present study was designed to extend these findings, in a real-life consumption setting. One hundred and fifteen participants took part in this study, and were assigned randomly to either a control or a scented condition. On arrival in the lab…
Alliesthesia is greater for odors of fatty foods than of non-fat foods
2011
International audience; Alliesthesia is the modulation of the rewarding value of a stimulus according to the internal state (hungry or satiated). This study aimed to evaluate this phenomenon as a function of the nature of the stimulus (odors evoking edible and non-edible items, and the food odors evoking fatty and non-fat foods) and to compare the effectiveness of two reward evaluations (measures of pleasantness and appetence) to reveal alliesthesia. The results showed that both fatty and non-fat food odors were judged as less pleasant and less appetent when the subjects were satiated than when they were hungry, whereas no such difference was observed for non-food odors. There was a greater…
