Summary: The addition of enzymes in fish feed can enhance the digestibility and absorption of plant- and animal-derived ingredients, leading to increased growth in aquacultural animals. Studies have shown that the use of digestive and non-digestive enzymes can improve the quality of fish feed, but critical steps in the production process should be carefully monitored to ensure enzyme activity is maintained.

Summary: In this study, the accumulation of lignin and changes in the transcriptome of postharvested water bamboo shoots under cold storage were investigated. It was found that lignin significantly accumulated in the shoots and the major up-regulated genes were involved in phenylpropanoid biosynthesis, plant-pathogen interactions, and starch and sucrose metabolism. The MAPK signaling pathway and RBOH genes were also up-regulated. Inhibition of RBOH oxidase hindered lignin deposition and biosynthesis, while H2O2 enhanced these processes, indicating that lignification of water bamboo shoots is regulated by RBOH-mediated ROS signaling.

Summary: This study investigated the lignification of water bamboo shoots and found that lignin significantly accumulated in the epidermis of cold storage shoots. The up-regulated genes involved in lignin biosynthesis and MAPK signaling pathway suggested that lignification is regulated by RBOH-mediated ROS signaling.

Summary: Reactive oxygen species (ROS) and the photoreceptor protein phytochrome B (phyB) play a key role in plant acclimation to stress. This study reveals that phyB and respiratory burst oxidase homolog proteins (RBOHs) act as part of a regulatory module that controls ROS production, stress-response gene expression, and plant acclimation to excess light stress. The findings also demonstrate that phyB can regulate ROS production even if it is restricted to the cytosol and that phyB and RBOHD/RBOHF co-regulate the expression of thousands of genes in response to light stress. Additionally, phyB is found to be necessary for ROS accumulation during heat, wounding, cold, and bacterial infection.

Summary: In this study, the researchers found that Brassinosteroids (BRs) promote adventitious root (AR) formation in pepper plants. They discovered that BRs regulate AR formation by modulating the production of apoplastic reactive oxygen species (ROS), including hydrogen peroxide (H2O2) and superoxide radical (O-2(& BULL;-)). The findings provide important insights into the regulatory roles of BRs and ROS in plant development.

Summary: Salt stress is a critical environmental factor that affects plant growth and development, especially crop productivity. Understanding how plants respond to salt stress is crucial for the development of salt-tolerant plants. In this study, we investigated the role of GmMPK6, a soybean mitogen-activated protein kinase, in regulating reactive oxygen species (ROS) generation and salt tolerance.

Summary: The study investigated the prediction of individual FE in European sea bass, identifying significant effects of temperature and population on FE and RMR. However, individual FE and RMR were not significantly correlated, indicating a need for further investigation into the relationship between metabolic rate and feed efficiency.

Summary: This study found that modification of apoplastic reactive oxygen species metabolism leads to growth retardation in plants under ammonium nutrition. Disruption of the D isoform of respiratory burst oxidase homolog resulted in lower apoplastic superoxide and hydrogen peroxide levels, downregulation of ROS sensing markers, and downregulation of ROS-responsive signaling pathway. These modifications make the transgenic plants more sensitive to the inhibitory effects of ammonium.

Summary: StCDPK23 is significantly induced at potato tuber wounds and regulates StRbohs to promote ROS production and suberin deposition during healing. The overexpression of StCDPK23 in tubers results in increased expression levels of StRbohs and enhanced production of O-2(-) and H2O2 during healing process.

Summary: Climate change poses a risk to the immune response against pathogens. A study on sea urchins exposed to temperatures above their comfort zone found that heat stress altered the distribution and activity of immune cells, increased lipid peroxidation, and reduced hydrogen peroxide production. The respiratory burst, a marker of immune response, was observed in all groups but was higher in the group kept at the optimal temperature. These findings suggest that high temperatures can impair immune cell functions and affect defense mechanisms against pathogens.

Summary: This research investigates the influence of process parameters on the mechanical characteristics of metal components produced through wire arc additive manufacturing (WAAM). The study found that WAAM-processed parts exhibit isotropic material properties and developed a surrogate model to accurately predict the effects of process parameters. Torch speed was identified as the most significant parameter, while wire feed speed primarily influenced yield strength, elastic modulus, and dimensional accuracy. This study provides valuable insights for predicting the mechanical properties of WAAM-produced parts.

Summary: This study assessed the effects of dietary insect meal from Hermetia illucens larvae on the gut microbial community of rainbow trout. The inclusion of insect meal in the diet led to an increase in beneficial bacteria and a reduction of pathogenic bacteria, shaping the metabolic activity of the trout gut microbiota. Insect meal from H. illucens is a promising protein source for trout nutrition, with potential to improve fish health by modulating the gut microbial community.

Summary: This study investigated the effects of fully replacing fishmeal with Tenebrio molitor larvae meal on the gut and skin microbiota of rainbow trout. The data showed slight changes in the microbiota after total replacement with insect meal, with no major effects on bacterial species richness and diversity. The study suggests that Tenebrio molitor larvae meal could be a viable alternative to fishmeal in aquafeeds.

Summary: The study aimed to evaluate the effects of plant-based oligosaccharides and phytogenic feed additives on the oxidative stress status and mucosal health of the gills of juvenile European sea bass. Results showed that these additives can protect the gill epithelia of sea bass from oxidative stress by modulating the expression of oxidative enzyme-related genes and reducing the density of PCNA+ cells in the gills.

Summary: P53 is a human protein consisting of five proposed domains, with a central DNA binding domain crucial for the direct binding of p53 to specific elements in the promoters of its target genes. Stimulated by cellular stressors, P53 acts as a tumor suppressor gene and plays significant roles in translational regulation and feedback processes. Various damage signals can activate the p53 pathway by affecting p53 stability, post-translational modifications, and recruitment to binding sites in chromatin. P53 functions as a transcriptional activator, mediating transcriptional changes that promote cell death, senescence, or cell cycle arrest. Due to its importance in tumor prevention, deregulation of p53 activity has been observed in human tumors. This article focuses on the mechanism of p53's suppressive effects in response to stress and the correlation between mutant p53 and different types of tumors.

Summary: This study was conducted to investigate the effects of spirulina on physicochemical parameters in carp. The results showed that fish fed with commercial spirulina pellets exhibited significantly increased growth rate and condition factor compared to the control group. Moreover, the spirulina-fed fish showed higher red and white blood cell counts, hemoglobin, and hematocrit, as well as reduced mean corpuscular hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin concentration. Additionally, there were significant differences in lipid profile parameters, with a decrease in low-density lipoprotein in the spirulina group. Overall, this study highlights the important role of spirulina supplementation in fish growth and hematological and biochemical parameters.

Summary: In this study, a feeding trial was conducted with rainbow trout to evaluate the bioavailability and efficacy of five different forms of methionine. The results showed that different forms of methionine had no effects on growth performance but led to changes in the whole-body composition of the fish. Additionally, specific forms of methionine affected hepatic methionine metabolism through different molecular pathways.
