... This study aims to investigate the potentiality of selenium in modulating arsenic stress in rice seedlings. Arsenate accumulation along with its transformation to arsenite was enhanced in arsenate exposed seedlings. Arsenite induced oxidative stress and severely affected the growth of the seedlings. Arsenate exposure caused an elevation in ascorbate and glutathione levels along with the activities ...

Abstract:
... Protein complexes mediated by various post-translational modifications (PTMs) play important roles in almost every aspect of biological processes. PTM-mediated protein complexes often have weak and transient binding properties, which limit their unbiased profiling especially in complex biological samples. Here, we developed a plug-and-play chemical proteomic approach for high-throughput analyis of ...

Abstract:
... Odorant-degrading enzymes (ODEs) play an important role in rapidly degrading and inactivating odorant molecules that have completed information transmission, as well as in maintaining the stability and sensitivity of insect olfactory sensing systems. Glutathione S-transferases (GSTs), as a group of ODEs, supposedly bear the ability to catalyze the conjugation of glutathione (GSH) and xenobiotic od ...

To enhance the salt resistance of seeds and seedlings for grapes under salt stress, multi-walled carbon nanotubes (MWCNTs) at 30, 60, 90, 150, and 180 μg/mL, respectively, were used to treat gape seedlings, and the seed germination and physiological characteristics grape seedlings were studied. MWCNTs at 90 μg/mL exhibited the best results, increased root length and germination rate compared with ...
... Arsenic (As) has aroused worldwide concern due to its accumulation in the food chain. Inoculated peanut plants with Bradyrhizobium sp. strains showing contrasting tolerance to arsenic (As), were exposed to a low arsenate (Asⱽ) for 30 days in order to decipher the participation of the antioxidant system, mainly related to glutathione (GSH) metabolism, together with the arsenate reductase (AR) activ ...

Abstract:
... Domestic sewage is an important source of pollutants in aquatic ecosystems and includes both microplastics (MPs) and pharmaceuticals and personal care products (PPCPs). This study sought to assess the biological effects of the interaction between plastic particles and the antibacterial agent triclosan (TCS). The study relied on the swamp ghost crab Ucides cordatus as a model. Herein polyethylene p ...

Abstract:
... The aim of the present study was to perform a pilot assessment and analysis of the oxidative stress (OS) level in four commercially important fish species (round goby, red mullet, sprat and horse mackerel) from different localities of the Bulgarian Black Sea coast. The fish were sampled during trawl selectivity experiments. The OS level in the fish was assessed by measuring lipid peroxidation (LPO ...
... Freshwater acidification and phenanthrene may result in complex adverse effects on aquatic animals. Juvenile Chinese mitten crabs (Eriocheir sinensis) were exposed to different pH levels (7.8, 6.5, and 5.5) under phenanthrene (PHE) (0 (control) and 50 μg/L) conditions for 14 days. Antioxidant and transcriptomic responses were determined under stress conditions to evaluate the physiological adaptat ...
... Thiamethoxam is an insecticide mainly used in agriculture to control insect pests. However, non-target insect species, such as honeybees, may also be impacted. In this study, adults of Apis mellifera intermissa were orally exposed under laboratory conditions to a sublethal concentration of thiamethoxam (CL₂₅₌ 0.17 ng/μl) for 9 days and the effects were evaluated at the biochemical level, by monito ...
... We conducted this study to investigate the positive effects of foliar-applied salicylic acid (SA) and kinetin (KN) in improving waterlogging stress tolerance, by upregulating reactive oxygen species (ROS) metabolism and antioxidant defense including glyoxalase system in soybean (Glycine max cv. Sohag) grown under different levels of waterlogging. Waterlogging was imposed on plants at 15 days after ...
... Obesity is a debilitating disorder with a variety of problems including oxidative stress, inflammation, and apoptosis. The aim of our study was to investigate the therapeutic role of bee bread on oxidative stress, apoptosis, and inflammation in the testis of obese rats. Thirty-two adult male Sprague Dawley rats, with weights between 230–300 g, were distributed into four groups (n = 8/group), namel ...
... This study investigated the effects of dietary nanoselenium (nano-Se) supplementation protecting from renal oxidative damages induced by mercury (Hg) exposure in laying hens. Furthermore, endoplasmic reticulum (ER) stress pathway was explored to reveal the protective mechanism of nano-Se. A total of 576 40-week-old Hyline-White laying hens were randomly allocated to 4 groups with 6 pens per group ...
... Fish transportation is a stressful event in aquaculture industry, which causes crowding stress, oxidative stress, hypoxia, and water pollution stress. Therefore, it is necessary to work on the methods for mitigation of such stresses. Glycine has been known for its roles in the antioxidant system and ammonia detoxification in fish. Therefore, the present study aimed at assessing the effects of diet ...
... The benefits of dietary glycine supplementation were investigated in common carp, Cyprinus carpio, following an acute ammonia challenge. Fish were fed diets supplemented with glycine (0, 2.5, 5 and 10 g/kg; named C, 2.5G, 5G and 10G, respectively) for 3 weeks, followed by 3‐h exposure to 0.5 mg/L unionized ammonia nitrogen. Plasma immunoglobulin levels showed no changes in relation to ammonia chal ...

... The addition of thiol compounds to o-quinones, as exemplified by the biologically relevant conjugation of cysteine to dopaquinone, displays an anomalous 1,6-type regiochemistry compared to the usual 1,4-nucleophilic addition, for example, by amines, which has so far eluded intensive investigations. By means of an integrated experimental and computational approach, herein, we provide evidence that ...
