However, their nutritional quality can be limited by the presence of antinutrients, such as phytic acid and trypsin inhibitors. Germination is a natural process that can enhance the nutritional value of legumes by reducing antinutrients and increasing the bioavailability of nutrients. The objective of this study was to evaluate the effect of soaking and germination on the antioxidant and nutritional attributes of soybean. Results showed that the germination process led to a significant increase (<em>p</em> ≤ 0.05) in the content of phenolic, flavonoids, and antioxidat activity (%) compounds following the 72-hour germination compared to samples from ungerminated soybeans. Strong correlations were concluded between antioxidant activity and total phenolic (R<sup>2</sup> 0.92), flavonoids (R<sup>2</sup> 0.82), and ascorbic acid (R<sup>2</sup> 0.99). The germination process also enhanced proteases activities, lipase activity, and protein digestibility. Concurrently, there was a significant reduction in phytic acid from 99.20 ± 2.56 to 73.39 ± 0.85, mg/100 g as well as trypsin inhibitors from 5.73 ± 0.116 to 2.91 ± 0.126 mg/g.

Our knowledge of the bio-response of Mo NPs in endothelial cells is lacking.

The study found that Mo NPs were highly biocompatible in HUVE cells and enhanced cellular antioxidant glutathione (GSH), significantly protecting cells against exogenous oxidants. Moreover, Mo NPs significantly restored the loss of mitochondrial membrane potential (MMP) determined by the Rh123 probe. They decreased reactive oxygen species (ROS) levels as measured by DHE and DCFH-DA probes. In light of Mo involvement in the nitric oxide (NO) metabolism and dependency of HUVE cells on NO signaling, intracellular NO was determined using DAR-2 fluorescent dye and the Griess assay. NO was not produced significantly by Mo NPs alone or t-BHP or H<sub>2</sub>O<sub>2</sub>. However, NO generation was significantly high when HUVE cells were co-exposed with Mo NPs and exogenous oxidants. Although the exact mechanism is unclear to us, our study concludes that the enhanced generation of NO under the co-exposure of oxidants with Mo NPs can impair the potential antioxidative property of Mo NPs, especially in endothelial cells.

A total of 62 genotypes germinated at 125 mM, showing significant phenotypic variation in traits such as root length, shoot length, fresh shoot weight, and dry shoot weight. Pearson’s correlation analysis revealed a strong positive correlation between most morpho-physiological traits, suggesting their interdependence. Eight salinity tolerance indices i.e., Fresh Weight Stress Tolerance Index (FWSI), Dry Weight Stress Tolerance Index (DWSI), Root Length Salinity Index (RLSI), Shoot Length Salinity Index (SLSI), Salinity Tolerance Index (STI), Salinity Susceptibility Index (SSI), Tolerance Index (TI), and Percent Reduction (PR) were calculated to assess genotypes response. Na<sup>+</sup> concentration and antioxidant activities significantly increased under salt stress compared to the control. The activities of antioxidant enzymes, as well as the levels of reactive oxygen species (ROS) such as H<sub>2</sub>O<sub>2</sub> and O<sub>2</sub><sup>−</sup>, were markedly higher under salt stress compared to the control. Hierarchical cluster analysis grouped genotypes into six clusters, with clusters V and VI comprising genotypes exhibiting higher salt tolerance based on high FWSI, DWSI, and STI values, and low PR, SSI, and TI values.

Our research aimed to comprehensively analyze its phytochemical constituents, and evaluate its antibacterial, antioxidant, antiviral, anti-inflammatory, antidiabetic, and antipyretic potentials. Utilizing a range of extracts including methanol (MtOH), ethanol (EtOH), ethyl acetate (EA), <em>n</em>-hexane (n-hex), dichloromethane (DCM), and aqueous (Aq), for effective extraction of phytochemicals from <em>C. edulis</em>. Standard biochemical assays and High-Performance Liquid Chromatography-Photodiode Array (HPLC-PDA) were used for analysis of phenolic compounds. Antibacterial effect(s) were confirmed through disc diffusion method and min inhibitory concentrations (MICs). The antioxidant activity was assessed through the Ferric Reducing Antioxidant Power (FRAP) assay and the DPPH radical scavenging method. <em>In vivo</em> antiviral potential was assessed through Hemagglutination (HA) test. Anti-inflammatory, antidiabetic, and antipyretic activities were performed on female albino rats using carrageenan, alloxan monohydrate and yeast-induced methods, respectively. Statistical analysis was done using standard one way ANOVA.Our findings revealed a rich diversity of phenolic compounds and the presence of proteins, alkaloids, and carbohydrates in <em>C. edulis</em>. MtOH and <em>n</em>-hex extracts demonstrated deep antiviral activity against various viral strains. <em>In vivo</em> toxicology studies indicated no significant toxicity at doses up to 5 g/kg.
