Abstract Abscisic acid (ABA), hydrogen peroxide (H₂O₂) and ascorbate (AsA)–glutathione (GSH) cycle are widely known for their participation in various stresses. However, the relationship between ABA and H₂O₂ levels and the AsA–GSH cycle under drought stress in wheat has not been studied. In this study, a hydroponic experiment was conducted in wheat seedlings subjected to 15% polyethylene glycol (PEG) 6000–induced dehydration. Drought stress caused the rapid accumulation of endogenous ABA and H₂O₂ and significantly decreased the number of root tips compared with the control. The application of ABA significantly increased the number of root tips, whereas the application of H₂O₂ markedly… More >

Abstract Background: Nano-selenium has been widely used in antiviral and anticancer therapy, and has the advantages of good targeting and low toxicity. For the first time, we combined male reproduction with nano-selenium to investigate its antioxidant effect. This study investigated the protective effect of lentinan functionalized selenium nanoparticles on oxidative stress injury of the hydrogen peroxide (H₂O₂)-induced Leydig cell line, TM3. Methods: The suitable concentration of nano-selenium treatment to promote cell proliferation was also discussed. The concentration of 4 μM could significantly promote the growth of TM3 cells. Oxidative stress damage was caused using an 800 μM concentration of hydrogen peroxide.… More >

Abstract A H₂O₂-induced oxidative stress injury cell model was established to investigate the antioxidant effect of nano-selenium on mouse spermatocyte lines and the regulation mechanism of the expression level and activity of selenium-containing antioxidant enzymes induced by oxidative stress. A safe and effective nano-drug system of functionalized selenium-containing nanoparticles (SeNPs) was developed with lentinan (LNT) (SeNPs@LNT). Mice spermatocyte line GC2-spg cells were treated with SeNPs@LNT (1, 2, 4, 8, 16, 32 μM) for 24–72 h to evaluate the cytotoxicity of selenium. GC2-spg cells were randomly divided into the following groups: control, hydrogen peroxide (H₂O₂), SeNPs@LNT, and H₂O₂+SeNPs@LNT groups. H₂O₂+SeNPs@LNT group was… More >

Abstract Nanosilver (10⁻⁹ m) refers to particles comprising 20–15,000 silver atoms, exhibiting high stability and specific surface area. At present, nanosilver has been used in agricultural cultivation and production. This study examined the effects of nanosilver on growth and development of rice root systems. Study results showed that fresh weight of rice belowground organs and root length both increased significantly by 5% and 25%, respectively, after rice radicles were treated with 2 ppm of nanosilver for three days. However, the H₂O₂ level reached its peak at 2 days from treatment, but the activities of the antioxidant enzymes CAT, APX, and GR… More >

Abstract Drought is the most common form of abiotic stress that reduces plant growth and productivity. It causes plant injuries through elevated production of reactive oxygen species (ROS). Potassium (K) is a vital plant nutrient that notably ameliorates the detrimental effect of drought stress in the plant. A pot experiment was conducted at the Laboratory of Plant Stress Responses, Faculty of Agriculture, Kagawa University, Japan, under controlled environment of green house to explore the role of K in mitigating drought severity in wheat (Triticum asevitum L.) seedlings. Three days after germination, seedlings were exposed to three water regimes viz., 100, 50,… More >

Abstract The cell activity of adipose-derived stem cells (ADSCs) is affected by the intracellular reactive oxygen species (ROS) and the level of autophagy. Previous studies reveal that acetyl-L-carnitine (ALC) possesses capacities of resisting oxidative stress and regulating autophagy. Activating molecule in Beclin1-regulated autophagy protein 1 (AMBRA1) plays a key role in initiating Beclin1-regulated autophagy. In the present study, we discovered ALC pretreatment (1 mM, 24 h) significantly increased the activity of ADSCs exposed to H₂O₂ (100 μM, 2 h) in vitro with improved stemness, and reduced the production of intracellular ROS. In addition, we found for the first time that ALC… More >

Abstract Maize being sub-tropical crop is sensitive to water deficit during the early growth stages; particularly clay-rich soil, due to the compaction of the soil. It is well-documented that potential sub-surface drip irrigation (SDI) (Full irrigation; SDIFull (100% field capacity (FC)), Deficit irrigation; SDIDeficit (70% FC)) improves water use efficiency, which leads to increased crop productivity; since it has a constraint that SDI excludes soil air around the root-zone during irrigation events, which alter the root function and crop performance. Additionally, in clayrich soils, the root system of plants generally suffers the limitation of oxygen, particularly the temporal hypoxia, and occasionally… More >

Abstract Selenium (Se) is an essential element for many organisms, although in high concentrations it may become toxic, leading to the generation of reactive oxygen species (ROS). In this study, bean plants received different application rates of Se (0, 10, 20, 40, 80, and 160 µM) in the form of selenite and selenate to evaluate the activity of the detoxifying enzymes of H₂O₂. The results indicated that the activity of these enzymes in bean plants depended on the chemical form of Se: selenite at rates of 20 µM or greater diminished biomass and yield, increasing the activity of superoxide dismutase (SOD).… More >
