Binge drinking is associated with an increased risk of cardiovascular events. Those events often happen within hours after alcohol is consumed. Apart from arrhythmias and changes in blood pressure, these events may be caused by an acute (i.e., occurring within a 24-h period) shift of the hemostatic balance in a thrombogenic direction. Alcohol can influence platelet aggregation and inhibit fibrinolysis, but little is known about its direct effect on coagulation. In the current study, parameters of coagulation, reflecting either stimulation or inhibition, were measured 5 and 15 h after the consumption of four (62.5 g of alcohol) and eight (125 g of alcohol) glasses of red wine. Both doses had no direct effect on activated cephalin time, thrombin-antithrombin complexes, factors VII and VIII, and von Willebrand factor. In contrast with the observed effects on thrombocytes and fibrinolysis, the consumption of large amounts of wine does not influence the coagulation pathway.

Over the last decade, research has emphasized the role of the microbiome in regulating cardiovascular physiology and disease progression. Understanding the interplay between wine polyphenols, the gut microbiota, and cardiovascular health could provide valuable insights for uncovering novel therapeutic strategies aimed at preventing and managing cardiovascular disease. In this study, two commercial red wines were subjected to dynamic gastrointestinal digestion (GIS) to monitor the flavanol-microbiota interaction by evaluating the resulting microbial metabolites.

The individual (poly)phenols of red wines cultivated in two different Western Balkan wine-growing regions were determined using the HPLC method, while the ABTS and DPPH tests were employed to investigate antioxidant activity. The reduction potential of antioxidants was determined by FRAP assay. Five distinct classes of phenolic compounds, including phenolic acids, flavan-3-ols, flavonols, stilbenes, and anthocyanins, were identified.

A simple and rapid colorimetric detection strategy, based on hydrogen bond identification of 6-thioguanine (6-TG) functionalized Au nanoparticles (AuNPs), is proposed for highly selective and sensitive determination of kanamycin (KA). In this strategy, the hydrogen bond interaction between 6-TG and kanamycin induces AuNPs to agglomerate, with a consequent color change of AuNPs from wine red to purple or even blue. The kanamycin concentrations can be quantified by employing UV-vis spectrophotometer.

The use of nanozymes for electrochemical detection in the food industry is an intriguing area of research. In this study, we synthesized a laccase mimicking the MnO@CeO nanozyme using a simple hydrothermal method, which was characterized by modern analytical methods, such as transmission electron microscope (TEM), X-ray diffraction (XRD), and energy dispersive X-ray spectroscopy (EDX), etc. We found that the addition of MnO significantly increased the laccase-like activity by 300% compared to CeO nanorods.

The winemaking process generates huge amounts of waste every year. Fermented grape pomace, the major by-waste product, holds significant value due to its chemical composition and technological properties. In this study a multi-omics approach was employed for the detailed molecular characterization of fermented grape pomace from Montepulciano grape, a widely used Italian red grape variety.
