In the present study, NMR-based urinary metabonomic profiles resulting from dosing with widely recognized microsomal enzyme inducers were evaluated in male rats. Wistar or Sprague-Dawley rats were dosed daily by oral gavage with phenobarbital (PB; 100 mg/kg), diallyl sulfide (DAS; 500 mg/kg), the investigational compound DMP-904 (150 mg/kg), or beta-naphthoflavone (BNF; 100 mg/kg) for 4 days, and urine was collected daily for analysis. Compounds known to increase cytochrome P450 2B enzymes, including PB, DAS and DMP-904, increased the urinary excretion of gulonic and ascorbic acid in a time-dependent manner, reaching a maximum following 3-4 days of dosing. In contrast, BNF, an agent that induces primarily Cyp1A enzymes, did not increase gulonic or ascorbic acid excretion, despite inducing Cyp1A1 more than 200-fold. Given the metabonomic results, hepatic transcriptional changes in the regulation of ascorbic acid biosynthesis were determined by RT-PCR. All Cyp2B inducers increased hepatic mRNA levels of aldo-keto reductase 1A1, an enzyme that catalyzes the formation of gulonic acid from glucuronate with concurrent decreased expression of both regucalcin (Rgn), the enzyme responsible for conversion of gulonic acid to gulono-1, 4-lactone and gulonolactone oxidase (Gulo), the rate-limiting enzyme in ascorbate biosynthesis. These effects would be expected to increase levels of gulonic acid. In addition, Cyp2B inducers also increased hepatic expression of enzymes regulating ascorbic acid reutilization including glutaredoxin reductase (Glrx2) and thioredoxin reductase (Txnrd1). In contrast, BNF did not effect hepatic expression of any enzyme regulating gulonic or ascorbic acid biosynthesis. Thus, some microsomal enzyme inducers alter transcriptional regulation of ascorbic acid biosynthesis, and these changes are detected by noninvasive metabonomic profiling. However, not all microsomal enzyme inducers appear to alter ascorbic acid metabolism. Finally, the work illustrates how metabonomic results can direct additional studies to determine the biochemical mechanisms underlying changes in urinary metabolite excretion.

Cerium oxide NPs (-CeO), with notable performance in various biological tests like redox activity, free radical scavenging, and biofilm inhibition, emerge as significant candidates to address issues in related areas. In this research, copper-decorated -CeO (Cu@-CeO) were first synthesized and then characterized using advanced techniques such as SEM-EDX, XRD, XPS, BET, and ICP-OES. The biochemical properties of the obtained Cu@-CeO nanostructure and its performance in polyethersulfone (PES) membranes were thoroughly investigated in this research study.

Resistant hypertension (RH) may cause severe target organ damage and poses significant challenges in the field of hypertension prevention and treatment. Mining biological characteristics is crucial for exploring the pathogenesis of RH and for early diagnosis and treatment. Although several single-omics studies have been conducted on RH, its complex pathogenesis has only been partially elucidated.

Biopolymer-based emulsion systems have been used for food preservation. In this study, mung bean protein (MBP) was added to konjac glucomannan (KGM)/curdlan-based camellia oil emulsion (KC-CO) to develop KCM-CO emulsion system. KCM-CO emulsions showed good compatibility and stability during storage.

In the present study, 85% aqueous ethanol extract of stem bark (MESB) showed the isolation of six bioactive compounds including myricanone (), myricanol-5-O-β-D-glucopyranoside (), myricetin (), myricolol (), β-sitosterol (), and β-sitosterol-D-glucoside (). The HPLC approach revealed as a key bioactive compound, with a 69% abundance in the crude ethanol (CE) extract. Furthermore, the CE was assessed for antioxidant activity using DPPH and hydroxyl radical tests, while purified compounds were examined for total antioxidant capacity using cyclic voltammetry and verified using the density functional theory (DFT) method.
