AI Article Synopsis
Article Abstract
Background: The volatile composition of Ruché, a red wine produced from a native grape in Piedmont (Italy), was investigated using headspace-solid phase microextraction (SPME) coupled to gas chromatography-mass spectrometry (GC/MS). The main volatile compounds of the wine were identified and quantified. Chemometric techniques were applied to identify features and possible clusters among the different samples.
Results: Forty volatile compounds were unambiguously identified in the 36 wine samples from different producers. The aroma profile was mainly composed of different alcohols and esters but also featured appreciable concentrations of terpenes, aldehydes, and octanoic acid. 2-Methyl benzaldehyde was identified for the first time. A high concentration of isoamyl alcohol significantly contributed to the aroma complexity. Differences between producers are highlighted.
Conclusion: The present work is the first report about the volatile profile of Ruché wines investigated by chemometric methods with quantitative results. Multivariate exploratory approaches revealed minor but distinct differences among the studied wines, likely attributable to variations in winemaking procedures. This study could be developed in future by investigating possible differences between wines according to different production vintages. © 2024 The Author(s).

Effect of Drug-to-Protein Reaction Kinetics on the Results of Thermal Proteome Profiling.

In this Letter, a two-term formalism for constructing protein solubility curves in thermal proteome profiling (TPP) is considered, which takes into account the efficiency of the drug-protein binding reaction. When the reaction is incomplete, this results in distortion of the otherwise sigmoidal shape of the curve after drug treatment, which is often observed in experiments. This distortion may be significant enough to disqualify the corresponding protein from the list of drug target candidates, thus negatively affecting the results of TPP data analysis.

Background: The consumption of ultra-processed foods has increased significantly worldwide and is associated with the rise in inflammatory bowel diseases. However, any causative factors and their underlying mechanisms are yet to be identified. This study aimed to further elucidate whether different types of the dietary emulsifier carrageenan (CGN) can alter the permeability and inflammatory state of the intestinal epithelium.
