为了更好地理解油料产品价格的波动规律，提升国内油料产品价格研究水平，以大豆、油菜、花生为油料作物的典型代表，以2011年2月—2019年12月油料产业链上各个环节月度价格数据为基础，采用三元VAR-BEKK-GARCH(1，1)模型，研究油料产业链上、中、下游产品的价格溢出效应。结果表明：大豆产业链各环节产品均存在价格均值溢出效应，油菜产业链上、中游之间没有价格均值溢出效应，花生产业链上、下游之间不存在价格均值溢出效应；在大豆、油菜和花生产业链中，各环节产品间价格双向波动溢出效应明显。政府应通过建立农业产业链价格监测体系、多元化的价格监测体系、稳定的市场调节机制等措施，促进相关农业产业链的协调发展。In order to better understand the fluctuation patterns of oilseed product prices and enhance the level of domestic research on oilseed product prices. Taking soybean, rapeseed and peanut as typical representatives of oilseed crops and using the monthly price data of each link in the oilseed industry chain from February 2011 to December 2019 as the basis, a trivariate VAR-BEKK-GARCH(1,1) model was adopted to study the price spillover effect of the upstream, midstream and downstream sectors of the oilseed industry chain. The results showed that there was a price mean spillover effect among all links in the soybean industry chain, and there was no price mean spillover effect between the upstream and midstream sectors of the rapeseed industry chain, and there was no price mean spillover effect between the upstream and downstream sectors of the peanut industry chain. The bidirectional price volatility spillover effects among the various links in the soybean, rapeseed and peanut industry chains was more significant. The government should promote the coordinated development of the relevant agricultural industry chain by establishing a price monitoring system for the agricultural industry chain, a diversified price monitoring system, and a stable market adjustment mechanism.

随着风电、光伏的大规模并网，电力系统面临灵活调节能力不足的挑战。水电运行灵活，通过与风光协同规划、互补运行，能有效平抑新能源出力波动，保障并网消纳。水风光协同规划的关键之一在于对水电灵活调节能力进行准确建模，其中振动区约束不容忽略。为此，提出了考虑水电振动区的水风光协同规划模型。该模型首先利用组合数学技术将水电机组振动区合成为电站振动区；然后，综合考虑振动区约束及梯级水力联系、水力发电方程等各项约束，实现对水电系统的准确建模；最后，耦合水电系统与新能源、联络线等相关运行约束形成水风光协同规划模型，并采用混合整数线性规划进行求解。以乌江流域某水风光互补系统为例，验证所提模型的有效性。

Neuronal synaptic plasticity involves adaptive changes in the structure and function of the nervous system, which can be categorized into structural and functional forms. This plasticity is crucial for both physiological and pathological brain states. The Rho GTPase family, comprising Rac1, Cdc42 and RhoA, plays distinct and significant roles in regulating neuronal synaptic plasticity. This review explores the influence of the Rho GTPase family on synaptic plasticity in drug addiction, thus enhancing our understanding of the molecular mechanisms underlying this condition.

Serine/arginine-rich splicing factor 6 (SRSF6) is a member of the serine and arginine-rich (SR) protein family, and it plays a crucial regulatory role in RNA splicing. Dysregulation of SRSF6 expression or function can lead to aberrant alternative splicing of certain genes, and contribute to the development and progression of inflammatory diseases, including tumors, diabetes, and pleural fibrosis. However, the role of SRSF6 in inflammation remains unclear. In this study, we found that the expression of inflammatory factors, including tumor necrosis factor-α (TNF-α) and cyclooxygenase-2 (COX-2), was induced by lipopolysaccharides (LPS). Concurrently, both the levels of SRSF6 mRNA and protein expression significantly increased with prolonged LPS stimulation (P<0.05). Furthermore, we investigated the change of SRSF6 expression on the expression of inflammatory factors. The results showed that upregulation of SRSF6 enhanced the expression of LPS-induced inflammatory factors (P<0.05), while downregulation of SRSF6 inhibited their expression (P<0.05). Additionally, the activation of the nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways was suppressed by SRSF6 knockdown (P<0.05), indicating that SRSF6 is involved in regulating inflammatory responses in macrophages. Myeloid differentiation factor 88 (MyD88) is a key adaptor protein in the TLR4 signaling pathway, with its splicing isoforms MyD88-L and MyD88-S exerting pro-inflammatory and anti-inflammatory effects, respectively. Analysis of RNA-binding protein database and RNA immunoprecipitation showed that SRSF6 binds to MyD88 mRNA. Splicing analysis indicated that downregulation of SRSF6 promoted the expression of the anti-inflammatory MyD88-S mRNA isoform (P<0.01). Moreover, knockdown of MyD88-S could rescue the expression of inflammatory factors suppressed by SRSF6 downregulation. These findings suggest that SRSF6 regulates MyD88 alternative splicing in macrophages, thereby affecting the activation of inflammatory signaling pathways and the expression of inflammatory factors. This study provides a foundation for further elucidating the role of SRSF6 in inflammatory diseases. [ABSTRACT FROM AUTHOR]

The problem of mycotoxin contamination in edible and forage agricultural products has become increasingly serious due to global warming and drought. Vomitoxin, also known as deoxynivalenol (DON), is one of the most common mycotoxins, mainly produced by Fusarium spp. and others, which not only causes great economic losses, but also seriously harms the health of humans and livestock. Mycotoxin de‐ toxification methods mainly include physical, chemical and biological methods, while biological detoxification methods based on microorganisms or enzymes have received more and more attention and application due to the advantages of strong specificity, high efficiency and no secondary pollution. This paper mainly reviews the toxicity of DON and its pathogenic mechanism to animals, as well as the research progress on the application of biological detoxification technology in feeds, aiming to provide reference for the biodetoxification of DON in feeds.

The research progress on simulation and optimization of pressure swing adsorption purification technology for low concentration coal is reviewed. The adsorbent and pressure swing adsorption process are briefly and clearly introduced. From the perspective of the development trend of adsorbents, simulation and optimization can improve the performance of adsorbents and the ratio of raw materials, and improve the effectiveness of adsorbents. From the perspective of the development trend of pressure swing adsorption, simulation and optimization of pressure swing adsorption equipment can make its automation effect better and economic benefit higher. This paper summarizes and points out that simulation and optimization play an important role in this technology from both perspectives, which improves the efficiency and productivity. While bringing a lot of convenience to the technology, there are also areas for further improvement from both perspectives. From the perspective of adsorbent, the simulation and optimization of multicomponent mixtures still need to be improved; from the perspective of pressure swing adsorption, there are still limitations in the dynamic change simulation in the actual operation, and the safety optimization in the operation of the device should be considered more.
