Ginger， rich in gingerols and shogaols， exhibits multiple biological properties. However， the mechanisms underlying its thermotolerance remain unclear. The study employed network pharmacology and experimental validation in Caenorhabditis elegans to investigate how gingerol-related compounds within ginger extract (GE) mitigated damage caused by heat stress (HS). A total of 18 types of gingerol analogues were identified in GE， among which 6-， 8-， and 10-gingerol， as well as 6-， 8-， and 10-shogaol were quantified. Collectively， these six compounds accounted for 54.4% of the total composition. Supplementation with 15 μg/mL GE significantly extended heat-stress lifespan by 20.30%， while the combination of the six major gingerols and shogaols at the same concentration prolonged lifespan by 18.93%. Additionally， pretreatment with GE and the combination alleviated HS-induced oxidative damage by eliminating reactive oxygen species (ROS) and upregulating antioxidant enzymes. Network pharmacology analysis suggested that the MAPK pathway may play a crucial role in thermotolerance. Experimental findings confirmed that ginger attenuated oxidative damage through the activation of SKN-1/Nrf2 and DAF-16/FOXO via the MAPK pathway. Moreover， GE stabilized mitochondrial membrane potential and restored ATP levels， thus preserving mitochondrial function during heat exposure. Further investigations using molecular docking and molecular dynamics simulations revealed that shogaols， with more stable binding affinities for KEAP1 protein， exhibited more potent effects than gingerols in prolonging lifespan and reducing ROS levels under HS conditions. In short， gingerol analogues from ginger conferred thermal resistance to nematodes by mitigating oxidative damage and mitochondrial dysfunction.

作者： Huifang Yang Ramy M.Khoder Shanbai Xiong Juan You Yueqi An Key Laboratory of Environment Correlative Dietology， Ministry of Education， College of Food Science and Technology， Huazhong Agricultural University Faculty of Agriculture， Benha University College of Health Science and Engineering， Hubei University

Grass carp fillets were susceptible to unpleasant fishiness during cold storage. To clarify the mechanism of fishy odor formation and achieve targeted regulation， volatile compounds， and lipid oxidation were investigated in grass carp fillets during cold storage （0-7d）. The lipid oxidation degree increased continually during cold storage， as evidenced by the change of AV， POV， TBARS， and HP. The activities of related enzymes (LOX， LPS， PLA[2]， and HPL) maintained a high level， reaching their maximums after 3-5 days. Free fatty acids exhibited a great downtrend， especially linoleic acid （18:2） and arachidonic acid （20:4）. Forty-five volatile compounds were identified by solvent-assisted flavor evaporation-gas chromatography-mass spectrometer， and the total contents of volatile compounds increased from 706.55 μg/kg （0d） to 1370.65 μg/kg （7d）. （Z）-4-heptenal，（E，E）-2，4-hexadienal， 1-penten-3-ol， nonanal， and （E）-2-heptenal were the key volatile compounds. The Pearson correlation showed a strong correlation between 47 differentially abundant lipids （variables important in projection > 1， P value < 0.05， and fold change > 2） and volatile compounds. During cold storage， lyso-phosphatidylcholine （20:4） and lyso-phosphatidylcholine （18:2） were selected as the main precursors of volatile compounds’ formation in grass carp fillets.

The authors of this paper have previously proposed the global virtual data space system (GVDS) to aggregate the scattered and autonomous storage resources in China’s national supercomputer grid (National Supercomputing Center in Guangzhou, National Supercomputing Center in Jinan, National Supercomputing Center in Changsha, Shanghai Supercomputing Center, and Computer Network Information Center in Chinese Academy of Sciences) into a storage system that spans the wide area network (WAN), which realizes the unified management of global storage resources in China. At present, the GVDS has been successfully deployed in the China National Grid environment. However, when accessing and sharing remote data in the WAN, the GVDS will cause redundant transmission of data and waste a lot of network bandwidth resources. In this paper, we propose an edge cache system as a supplementary system of the GVDS to improve the performance of upper-level applications accessing and sharing remote data. Specifically, we first designs the architecture of the edge cache system, and then study the key technologies of this architecture: the edge cache index mechanism based on double-layer hashing, the edge cache replacement strategy based on the GDSF algorithm, the request routing based on consistent hashing method, and the cluster member maintenance method based on the SWIM protocol. The experimental results show that the edge cache system has successfully implemented the relevant operation functions (read, write, deletion, modification, etc.) and is compatible with the POSIX interface in terms of function. Further, it can greatly reduce the amount of data transmission and increase the data access bandwidth when the accessed file is located at the edge cache system in terms of performance, i.e., its performance is close to the performance of the network file system in the local area network (LAN).

Solar-driven energy conversion is a promising technology for a sustainable energy future and environmental remediation, and an efficient catalyst is a key factor. Recently, metal halide perovskites(MHPs) have emerged as promising photocatalysts due to their exceptional photoelectronic properties and low-cost solution processing, enabling successful applications in H_(2) evolution, CO_(2) reduction, organic synthesis, and pollutant degradation. Despite these successes, the practical applications of MHPs are limited by their water instability. In this review, the recently developed strategies driving MHPcatalyzed reactions in aqueous media are outlined. We first articulate the structures and properties of MHPs, followed by elaborating on the origin of instability in MHPs. Then, we highlight the advances in solar-driven MHPbased catalytic systems in aqueous solutions, focusing on developing external protection strategies and intrinsically water-stable MHP materials. With each approach offering peculiar sets of advantages and challenges, we conclude by outlining potentially promising opportunities and directions for MHP-based photocatalysis research in aqueous conditions moving forward. We anticipate that this timely review will provide some inspiration for the design of MHPbased photocatalysts, manifestly stimulating their applications in aqueous environments for solar-to-chemical energy conversion.

An outstanding neuroprotection in diabetic model via wheat bran-derived peptides intervention and potent regulation pathways

Cerebral oxidative stress and inflammation play an important role in the pathophysiology of diabetes-related cognitive impairment. Therefore， the peptide-rich mixture from wheat bran （referred as EHWB） was adopted to investigate its neuroprotective effect on H2O2-damaged SH-SY5Y cells and diabetic rats. Results showed that pre-incubation of EHWB alleviated oxidative stress in H2O2-damaged SH-SY5Y cells by increasing levels of superoxide dismutase （SOD）， glutathione （GSH）， brain derived neurotrophic factor （BDNF）， and reducing the generation of reactive oxygen species （ROS）. Furthermore， EHWB pretreatment improved cell cycle arrest in the G2/M phase. More importantly， this study， at least in part， confirmed that EHWB could penetrate through the blood-brain barrier to exert a neuroprotective effect through an in vitro transwell model. EHWB administration improved the behavior performance in diabetic rats， including explorative activities， spatial learning and memory. Particularly， this study found that EHWB markedly suppressed the astrocyte activation， as shown by the downregulation of glial fibrillary acidic protein （GFAP） in the CA1 region of the hippocampus， but not for other regions or microglia. The potential mechanism of cognition enhancement of EHWB might be related to the signaling cascades induced by BDNF via the BDNF/TrkB/CREB pathway. This study might highlight a new ingredient for the prevention and protection of cognitive dysfunction.

To explore the application potential of ceramic matrix composite (CMC) mechanical connection structure in aero-engine， the failure mode and failure process of plain woven SiC/SiC perforated plate-metal pin connection structure under tension state were studied by combining test and numerical simulation. The deformation and failure process of the test specimens in real-time were observed through digital image correlation (DIC) technology. The main failure mode of the connected structure arising from the shear failure combined with delamination damage was revealed by test results. Based on the cohesive zone model (CZM)，the failure load，failure mode and delamination damage of the plain woven SiC/SiC perforated plate were predicted by using the progressive damage analysis method (PDA). Good consistency between the numerical failure predictions and the test results was obtained，and the failure load prediction error was less than 10%，indicating the validity of the numerical model for the failure analysis of connection structure. © 2025 Beijing University of Aeronautics and Astronautics (BUAA).

Heterogeneous distribution of Cardinium in whitefly populations is associated with host nuclear genetic background

Inherited bacterial symbionts are very common in arthropods, but infection frequency can vary widely among populations. Experiments and interpopulation comparisons suggest that host genetic background might be important in explaining this variation. Our extensive field investigation showed that the infection pattern of the facultative symbiont Cardinium was heterogeneous across geographical populations of the invasive whitefly Bemisia tabaci Mediterranean (MED) in China, with genetic nuclear differences evident in 2 of the populations: 1 with a low infection rate (SD line) and 1 with a high infection rate (HaN line). However, whether the heterogeneous frequency of Cardinium is associated with the host genetic background remains poorly understood. Here, we compared the fitness of the Cardinium-infected and uninfected sublines with similar nuclear genetic backgrounds from SD and HaN lines, respectively, and further determine whether host extranuclear or nuclear genotype influenced the Cardinium–host phenotype by performing 2 new introgression series of 6 generations between SD and HaN lines (i.e., Cardinium-infected females of SD were backcrossed with uninfected males of HaN, and vice versa). The results showed that Cardinium provides marginal fitness benefits in the SD line, whereas Cardinium provides strong fitness benefits in the HaN line. Further, both Cardinium and the Cardinium–host nuclear interaction influence the fecundity and pre-adult survival rate of B. tabaci, whereas the extranuclear genotype does not. In conclusion, our results provide evidence that Cardinium-mediated fitness effects were closely associated with the host genetic background, which provides a fundamental basis for understanding the mechanism underlying the heterogeneous distribution of Cardinium in B. tabaci MED populations across China.
