Scope: Knowledge of in vivo polyphenol metabolites derived from the consumption of red wine could be key to understanding its health benefits. This work aimed to predict the wine polyphenol metabolic space in biofluids by using all available data compiled in the Phenol-Explorer database.
Methods And Results: A search strategy was developed for Phenol-Explorer to obtain the widest range of metabolites related to wine consumption. A total of 97 metabolites have been described in intervention studies with wine and related products (n = 37), and after consumption of pure compounds known to be wine constituents (n = 90). These 97 metabolites, derived from host and microbial metabolism of several classes of polyphenols, were found in plasma and urine samples and some of them have demonstrated higher or lower biological activities than the parent compound in in vitro studies. The metabolites have been linked to generate, for the first time, a global pathway map of wine in vivo polyphenol metabolism.
Conclusion: The retrieval of the widest range of metabolites so far described and their assembly as a metabolic pathway map could aid the identification of possible biomarkers of wine consumption and improve current understanding of the health effects of wine consumption.

Harnessing the potential of Cupriavidus necator for CO capture from alcoholic fermentation and its bioconversion into poly(3-hydroxybutyrate).
Bioresour Technol

Department of Biology, University of Padova, 35131 Padova, Italy. Electronic address:
The fermentation process in alcoholic beverage production converts sugars into ethanol and CO, releasing significant amounts of greenhouse gases. Here, Cupriavidus necator DSM 545 was grown autotrophically using gas derived from alcoholic fermentation, using a fed-batch bottle system. Nutrient starvation was applied to induce intracellular accumulation of poly(3-hydroxybutyrate) (PHB), a bioplastic polymer, for bioconversion of CO-rich waste gas into PHB.

Consumption of contaminated wines is a significant source of ochratoxin A (OTA) intake in humans, yet existing techniques for OTA removal are inadequate. This study constructs a TiO/SiO/g-CN catalyst (TiSiMs-TCN) with a tubular structure, capable of efficiently removing OTA from both simulated and real wines under visible light irradiation. The results of experiments, characterizations, and theoretical calculations demonstrate that the incorporation of silica enhances the adsorption capacity for OTA, and the tubular structure improves the catalyst's photoelectric properties.

Fumonisins, a class of mycotoxins predominantly produced by species, represent a major threat to food safety and public health due to their widespread occurrence in staple crops including peanuts, wine, rice, sorghum, and mainly in maize and maize-based food and feed products. Although fumonisins occur in different groups, the fumonisin B series, particularly fumonisin B1 (FB1) and fumonisin B2 (FB2), are the most prevalent and toxic in this group of mycotoxins and are of public health significance due to the many debilitating human and animal diseases and mycotoxicosis they cause and their classification as by the International Agency for Research on Cancer (IARC) as a class 2B carcinogen (probable human carcinogen). This has made them one of the most regulated mycotoxins, with stringent regulatory limits on their levels in food and feeds destined for human and animal consumption, especially maize and maize-based products.

: Chronic kidney disease (CKD) geriatric patients experience a premature aging process, compared with the general population of the same age and sex. The uremic milieu is capable of enhancing oxidative stress (OS) and microinflammation, leading to a pro-aging mechanism and an increased protein catabolism. Moreover, cognitive disorders are observed.
