Abstract:
... In order to answer the question whether coronaviruses (CoVs) can be transmitted via foods, this review made a comparison between CoVs with the most recognized foodborne virus, human noroviruses (NoVs). As a result, although CoVs indeed have shown the possibilities to remain infectious on foods and/or food packaging materials long enough (from several days to several weeks) to potentially cause tra ...

Abstract:
... Alcohol is an ancestral beverage. Both divinized and demonized, it is nowadays at the heart of a great controversy at health and social levels. Its consumption is subject to great control, consumption thresholds are instituted (i.e. WHO), limits imposed. However, it must be admitted that the consumption of alcohol is regulated by culture, contexts and identity. This article aims to show that the t ...

Abstract:
... Alcohol dehydrogenases (ADHs) catalyze the reversible reduction of a carbonyl group to its corresponding alcohol. ADHs are widely employed for organic synthesis due to their lack of harm to the environment, broad substrate acceptance, and high enantioselectivity. This review focuses on the impact and relevance of ADH enantioselectivities on their biotechnological application. Stereoselective ADHs ...

Abstract:
... We explored the wetting regimes inherent to liquid marbles filled with aqueous alcohol placed on water layers of various thicknesses. Very different wetting regimes are observed, depending on the thickness h of the supporting water layer: (i) Marangoni soluto-capillary flow-driven self-propulsion for h ≥ 1.2 mm; (ii) dewetting followed by the retraction of the triple line for 0.63 mm < h < 1.2 mm; ...

Abstract:
... The (polyenoyl)tetramic acid militarinone C (1) heads a family of seven members. Before our work, the configuration of C-5 was unknown whereas the configurations of C-8′ and C-10′ were either (R,R) or (S,S). We synthesized the four stereoisomers of constitution 1, which conform with these insights. This included cross-coupling both enantiomers of the western building block (8) with both enantiomer ...

Abstract:
... A Rh(II)-catalyzed formal [3+3] cyclization of diazonaphthoquinones and propargyl alcohol is reported to afford 2,3-dihydro-1,4-benzodioxins. Various terminal propargyl alcohols react with diazonapthoquinone in the presence of Rh₂(OAc)₄ to give the corresponding dihydrodioxins in good to high yields. However, dihydrodioxins are not formed in the reaction of internal propargyl alcohols, and the O–H ...

Abstract:
... Alcohol consumption has been linked to a wide range of social and health problems, and it is known that drinking among older age groups has been increasing. Relatively little qualitative research has examined how older drinkers make sense of their drinking practices, including how they seek to normalise their consumption when talking about it. This paper reports on a qualitative interview study wi ...
