s an accelerated absorption in vivo and its effect time was prolonged, and the observed improvement of anti-AGMI effect was achieved through anti-oxidation and anti-inflammation regulation. Seed biopriming is an emerging technique to enhance seed germination under stress conditions. An integrated approach of tomato seed biopriming with ascorbic acid, Trichoderma asperellum BHU P-1 and Ochrobactrum sp. BHU PB-1 was applied to observe the response against wilt pathogen of tomato Fusarium oxysporum f. sp. lycopersici (FOL). Tomato seeds bioprimed with the aforementioned application expressed augmented seed germination and activated of defense response. Seed germination was recorded higher (80 %) at low concentration (1 pM) of ascorbic acid as compared to high concentration of 1 mM (41 %). Combination of both ascorbic acid and antagonistic microbe treatments (T5 & T6) significantly reduced disease incidence (up to 28 %) in tomato plants at 10 days. T5 and T6 treated plants exhibited higher accumulation of total phenol content and increased activity of Phenylammonia lyase (PAL), Peroxidase (PO), Chitinase (Chi) and Polyphenol oxidase (PPO) as compared to control (T1) plants. ROS formation in the form of H2O2 was also found to be reduced in combined treatment. Histochemical analysis revealed that phenylpropanoid pathway (lignin deposition) was more activated in combined priming treatment plants as compared to individual treatment upon challenge inoculation with FOL. Transcript expression analysis of defense genes confirmed the up-regulation of PAL (2.1 fold), Chi (0.92 fold), Pathogenesis related proteins (PR) (1.58 fold) and Lipoxygenase (Lox) (0.72 fold) in T6 treatment as compared to T1 treatment plants at 96 h. This study reveals that ascorbic acid treatment with antagonistic microbes through seed priming effectively induced seed germination and elicited defense mechanism to control wilt disease in tomato plants. The competence of hydrophilic interaction (HILIC) and reversed phase liquid chromatography (RPLC) modes, employing two new stationary phases triazole- and pentabromobenzyl-bonded silica (PBr), respectively, was inspected for separation of two polar basic analytes famotidine (FAM) and its acidic degradant famotidone (FON). Comparison of the chromatographic efficiency, greenness, and economy aspects showed that the RPLC is superior to the HILIC. Hence, the RPLC method was adopted and validated adhering to the FDA guidelines showing excellent linearity for FAM (1.0-20.0 μg/mL) with a detection limit of 0.14 μg/mL. The method was applied to study the behavior of FAM in simulated gastric juice (SGJ), where it exhibited rapid degradation yielding FON. This degradation pathway is a probable major reason for the poor bioavailability of FAM. The kinetic study of the gastric degradation of FAM in SGJ demonstrated pseudo-first order reaction with a rate constant of 8.1 × 10-3 min-1. Moreover, FAM degradation has been proven to be pH-dependent and catalyzed by the gastric juice components. Hence, in situ buffered dosage form is recommended to overcome or decrease this problem. Molecular docking study shows that FON is missing a crucial stabilizing interaction with the key amino acid Asp98 causing a reduced activity at hH2R receptor relative to FAM. Selleck 2-NBDG Moreover, ADMET properties prediction revealed some differences in the toxicity, pharmacokinetics, metabolism, and solubility profiles of FAM and FON. Oxidative stress is a pathological condition characterized by an imbalance between body's antioxidant defenses and oxidizing agents, resulting in damage of endogenous molecules. These products can be used as markers of oxidative conditions; in particular, isoprostanes (IsoPs) come from the reaction of arachidonic acid with reactive oxygen species (ROS) and are currently defined as gold markers of oxidative stress in urine. Our main goal was the development of a reliable analytical method for the determination and quantification of the IsoPs in human urine by dispersive Liquid-Liquid Micro Extraction (dLLME) coupled with micro Solid Phase Extraction (μSPE) clean-up and HPLC-MS/MS analysis. The selected compounds are present in very small concentration in urine, furthermore, due to relevant matrix effect, they are challenging for ESI-MS/MS analysis. This approach provided selectivity and sensitivity for 8-isoprotaglandine F2α (8-iso-PGF2α), the "gold" OS marker, together with the main isomers. dLLME extraction allowed a significant enrichment factor and μSPE clean-up provided the removal of ion-suppressing compounds from the sample resulting in low matrix effect. The chromatographic separation was also challenging as the target compounds possess very similar chemical characteristics, so experimental conditions were carefully tuned. The reported method represents a useful tool for the detection of IsoPs in urine taking advantage of the combination of dLLME extraction and μSPE clean-up; overall recoveries were above 50 % and matrix effects were ≤15 %, with LOQs ranging between 0.020 and 0.060 ng mL-1. The procedure is easy to use and rapid allowing the removal of interfering compounds and matrix effect maintaining a highly sensitive determination. A novel method was developed for the determination of aucubin in rat serum by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) with supramolecular solvent (SUPRAS)-based dispersive liquid-liquid microextraction (DLLME). The SUPRAS was prepared with pentanol as extraction solvent and tetrahydrofuran as dispersing agent. Based on single factor test and response surface methodology, critical parameters were optimized as 1 mL of pentanol as extraction solvent, 4 mL of tetrahydrofuran as dispersing agent, 200 μL of SUPRAS, and vortex duration of 2.5 min. The established method was validated in terms of selectivity, linearity, accuracy, precision, recovery, stability, and applied to a pharmacokinetic study on type 1 diabetes model rats intraperitoneally administered with aucubin. The experimental results showed that the maximum concentration in serum (Cmax) and area under the serum concentration versus time curve (AUC) of aucubin in type 1 diabetic rats were higher than those in normal rats.
