Abstract:
... Metal-nitrogen-doped carbon single-atom nanozymes (M − NC SAzymes) have tremendous prospects to replace natural enzymes for the treatment of reactive oxygen species (ROS)-related diseases. However, developing a pyrolysis-free and universal synthesis of M − NC SAzymes with robust enzyme-mimicking activity still remains a challenge. Herein, a promising cytoprotective agent (Fe-NC SAzymes) with multi ...

Abstract:
... In Arabidopsis thaliana, NAC-like and activated by AP3/PI (NAP) are NAC transcription factors that regulate leaf senescence and environment stress. Gene LbNAP, which has a typical NAC region, was cloned from lily petals. Our results indicated that LbNAP was located in the nucleus, and the gene had transcriptional activation activity. Further studies on LbNAP expression showed that it was lowest in ...
... Cyanobacteria and green algae are the OECD recommended test organisms for environmental toxicity assessments of chemicals. Whether the differences in these two species' responses to the identical chemical affect the assessment outcomes is a question worth investigating. Firstly, we investigated the distinct resistance mechanisms of Synechococcus sp. (cyanobacteria) and R. subcapitata (green algae) ...
... Once harvested, papaya fruit is prone to rapid deterioration and spoilage by microorganisms leading to food loss. The current study aimed to evaluate the effect of kojic acid (KA) treatments (2 mM and 5 mM) on the resistance of postharvest papaya against Colletotrichum brevisporum, a hazardous fungal pathogen. The results indicated that KA treatment decreased the lesion length in papayas by 30% af ...
... In order to avoid pyridine volatilization in the conventional aerobic system based on bubble aeration, an algal-bacterial symbiotic system based on photosynthetic oxygenation was developed. Nonetheless, pyridine at high concentration would inhibit algal growth and photosynthetic activity, and thus decrease oxygen production efficiency. An external-loop split-type dynamic membrane photobioreactor s ...

Abstract:
... Experiments were performed to explore the impact of sulfur nanoparticles (SNPs) on growth, Cu accumulation, and physiological and biochemical responses of oilseed rape (Brassica napus L.) inoculated with 5 mg/L Cu-amended MS medium supplemented with or without 300 mg/L SNPs exposure. Cu exerted severe phytotoxicity and inhibited plant growth. SNPs application enhanced the shoot height, root length ...

Abstract:
... The wastewater discharge from the process of chrome plating, which contains 6:2 chlorinated polyfluorinated ether sulfonate (F-53B) and chromium (Cr), may be toxic to biofilm. In this study we found that the biofilm formed by Pseudomonas aeruginosa PAO1 was inhibited by exposure to a combination of F-53B and Cr(VI). The combined pollution damaged the cell membranes and the structure of the biofilm ...

Abstract:
... Triclocarban (TCC) is an emerging environmental contaminant, posing potential ecological risks. Displaying a high accumulation effect and 120-day half-life in the soil environment, the toxic effects of TCC to soil organisms have been widely reported. Previous studies have confirmed that TCC can induce the oxidative stress and changes in superoxide dismutase (SOD) and catalase (CAT) activities in e ...
... Stressful situations induce an increase in the production of reactive oxygen species (ROS) which can lead to molecular damage and alteration of cell function. The introduction of new potential predators induces physiological stress in native fauna. However, behavioral responses have been reported in preys, demonstrating an induction of the defenses against alien species. Behavioral and antioxidant ...

Abstract:
... Hybridization is a widely used and effective method in grouper breeding. In this study, we constructed full-sib families of brown-marbled grouper (Epinephelus fuscoguttatus), Jinhu grouper (E. fuscoguttatus ♀ × E. tukula ♂), and Hulong grouper (E. fuscoguttatus ♀ × E. lanceolatus ♂) and compared the growth characteristics under industrial conditions. The body weight of Jinhu grouper was 1.49 times ...
... With the rapid development of hydropower facility construction, the total dissolved gas (TDG) generated by dam discharge is seriously threatening the survival of fish and has become an ecological environmental issue of global concern. However, how TDG affects fish physiology and the underlying molecular mechanism remain poorly known. In this study, Acipenser dabryanus, an ancient living fossil tha ...
... Tungsten trioxide (WO₃)-based nanoparticles (NPs) are gaining popularity because of their exciting potential for photocatalytic applications; however, the toxic potential of WO₃-based NPs remains a concern. In this study, we evaluated the toxic risk of WO₃ NPs and hydrated WO₃ NPs (WO₃·H₂O NPs) using lung cells and explored the underlying mechanism. WO₃ NPs and WO₃·H₂O NPs significantly decreased ...
... This experimental study was conducted to investigate the effects of β-aminobutyric acid (BABA) on chilling injury in cold-stored cucumber fruit. Results showed that BABA decreased the development of chilling injury in cucumber fruit. BABA-treated fruit exhibited elevated antioxidant ability, indicated by high activities of superoxide dismutase (SOD) and catalase (CAT) and low levels of hydrogen pe ...
... The aim of this study was to evaluate the physiological and biochemical heat responses of grafted tomato (Solanum lycopersicum L.) seedlings and their changes during the post-stress recovery period. Heat-tolerant ‘Celebrity’ and heat-sensitive ‘Arkansas Traveler’ tomatoes were grafted onto a commercial ‘Maxifort’ rootstock, and transplants were grown in growth chambers for 14 days of heat treatmen ...
... Antrodia camphorata is a genus of wood-rot basidiomycete in the family Fomitopsidaceae. It is a valuable medicinal fungus in China that contains more than 78 kinds of active compounds. A. camphorata has good protection effects on the liver, especially on alcoholic liver injury (ALI). This paper summarizes the complex occurrence and development of alcoholic liver disease (ALD). In addition, the eff ...

Abstract:
... To determine the optimal light color and photoperiod conditions for red claw crayfish juveniles, we studied the effects of these factors on their survival, growth, monoamine content, antioxidant capacity, nonspecific immune index, and the expression of EcR and α-AMY genes. Experiments involving five light color groups (red, green, blue, yellow, and white light), five photoperiod groups (0 L:24D, 6 ...
... A feeding experiment was carried out to compare the effects of dietary synthetic astaxanthin and Haematococcus pluvialis on growth, antioxidant capacity, immune response and hepato-morphology of Oncorhynchus mykiss under cage culture with flowing freshwater. Three isonitrogenous and isolipidic diets were formulated with or without synthetic astaxanthin and H. pluvialis and were administered to O. ...
... Pepper/Chilli leaf curl virus disease (PepLCVD/ChiLCVD) is the most destructive disease of pepper that seriously reduced pepper production. The LCVD is transmitted by vector whitefly (Bemisia tabaci) so efficiently that even single whitefly is able to transmit the virus. The effective way to manage the LCVD in pepper is to introduce LCVD resistance into agronomically desired cultivars, but the lac ...
... The purpose of this study was to evaluate effects of dietary quercetin (Que) on growth performance and disease resistance mechanism of Litopenaeus vannamei. Shrimp were randomly divided into 4 groups, with 3 replicants in each group and 70 shrimp in each replicants. The contents of Que. in the four groups were 0, 0.25, 0.5 and 1 g kg⁻¹, respectively. Samples were taken after 56 days, followed by a ...
