Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (EVG/COBI/FTC/TAF) is specified in its package insert to be taken with food to obtain sufficient exposure of EVG. It has been reported that a nutritional protein-rich drink shows comparable pharmacokinetics (PK) of EVG to those with a standard breakfast. In this study, the PK profiles of EVG and COBI were evaluated by administration of a single dose of EVG/COBI/FTC/TAF, after ingestion of either a nutritional protein-rich drink, milk, or apple juice. The geometric means for C and AUC of EVG following milk ingestion slightly decreased by 21% and 14%, respectively, and those following apple juice ingestion decreased by 67% and 61%, respectively, compared with a nutritional protein-rich drink. There were no differences in any PK parameters of COBI. Therefore, taking EVG/COBI/FTC/TAF after milk or apple juice ingestion appeared to be not appropriate. However, for plasma trough concentrations (C ), it is known that C is best correlated with the efficacy of EVG. The mean C of EVG after milk ingestion was 620.6 ng/mL, which was more than 10-fold the protein binding-adjusted 95% inhibitory concentration. With all the above considerations, it was concluded that taking EVG/COBI/FTC/TAF with milk could be an option to maintain sufficient plasma concentrations of EVG.

Apple pomace, a by-product of apple juice production, is typically discarded as waste. Recent approaches have focused on utilizing apple pomace by extracting beneficial bioactive compounds, such as antioxidant phenolic compounds (PCs). Before these PC-rich extracts can be used in food products, they must undergo food preservation and processing methods.

The increasing trend of diet-related chronic diseases has stimulated research into developing new food products and beverages with health-promoting potential. At the same time, new resources, including plant by-products, are currently being investigated as a sustainable source of bioactive compounds. In this context, the present study focused on the enrichment of apple juice with anthocyanins and other phenolic compounds by direct ultrasound-assisted extraction (UAE) from bilberry pomace.

For separation of deoxyribonucleic acid (DNA), positively charged amino-modified magnetic nanoparticles (MN) can effectively adsorb negatively charged DNA through electrostatic interaction. However, the reported preparation of amino-modified MN is usually tedious and time-consuming. Therefore, a simple synthesis method of amino-modified MN is necessary for DNA extraction.

In this study, DL-phenylalanine modified with a multiwall carbon nanotube paste electrode is used as advanced electrochemical sensor for analysing of 0.1 mM caffeic acid (CFA) with simultaneous detection of riboflavin (RFN). The developed sensors include electrochemically polymerized DL-phenylalanine (DL-PA) modified multiwall carbon nanotube paste electrode [DL-PAMMCNTPE] and bare multiwall carbon nanotube paste electrode [BMCNTPE].
