BACKGROUND Ferroptosis is involved in developing inflammatory diseases;yet,its role in acute hypertriglyceridemic pancreatitis(HTGP)remains *** To explore whether ferroptosis is involved in the process of HTGP and elucidate its potential *** An HTGP mouse model was induced using intraperitoneal injection of P-407 and caerulein(CAE).Then,pancreatic tissues from the model animals were subjected to proteome sequencing *** pathological changes and scores of the pancreas,lung,and kidney were determined using hematoxylin-eosin *** levels of serum amylase(AMY),triglyceride,and total cholesterol were measured with an automatic blood cell ***,the serum levels of tumor necrosis factor(TNF)-α,interleukin(IL)-6,and IL-1βwere determined by enzyme linked immunosorbent ***(MDA),glutathione(GSH),and Fe^(2+)were detected in the ***,immunohistochemistry was performed to assess the expression of ferroptosis-related *** Proteome sequencing revealed that ferroptosis was involved in the process of HTGP and that NADPH oxidase(NOX)2 may participate in ferroptosis ***,the levels of serum AMY,TNF-α,IL-6,and IL-1βwere significantly increased,MDA and Fe^(2+)were upregulated,GSH and ferroptosis-related proteins were reduced,and the injury of the pancreas,lung,and kidney were aggravated in the P407+CAE group compared to CAE and wild type groups(all P<0.05).Notably,the inhibition of ferroptosis and NOX2 attenuated the pathological damage and the release of TNF-α,IL-6,and IL-1βin the serum of the *** Ferroptosis was found to have an important role in HTGP and may be considered a potential target for clinical treatment.

Identification of a fatty acid synthase gene(FAS1)from Laodelphax striatellus planthoppers contributing to fecundity

引用

Insect Science 2023年第3期30卷 599-610页

作者： Jia-Yan Cheng pei-han yu Xue Xia Ru Zhang Li-Hua Wang Ji-Chao Fang Ary AHoffmann Guang-Hua Luo Cllege of Plant Protection Nanjing Agricultural UniversityNanjingChina Institute of Plant Protection Jiangsu Academy of Agricultural SciencesJiangsu Key Laboratory for Food and Safety-State Key Laboratory Cultivation Base of Ministry of Science and TechnologyNanjingChina School of BioSciences Bio21 InstituteUniversity of MelbourneParkvilleVictoriaAustralia

Fatty acid synthase (FAS) is a multifunctional enzyme that plays an important role in the formation of fatty acids. The fatty acids take part in many processes, such as cell signaling and energy metabolism, and in insects they are important in both cuticular hydrocarbon (CHC) formation and reproduction. Here we characterized the sequence structure and function of an FAS from the small brown planthopper (SBPH), Laodelphax striatellus. The full-length open reading frame (ORF) sequence of LsFAS1 was 7122 bp, encoding a predicted protein of 2373 amino acid residues. There were 7 functional domains in the LsFAS1 protein sequence. Gene expression screening by real-time quantitative polymerase chain reaction (RT-qPCR) showed that LsFAS1 was expressed in all developmental stages. Relative expression was highest at the 4th-instar and female adult stages. Among different tissues, the expression level of LsFAS1 in the ovary was the highest. Phylogenetic analysis showed that LsFAS1 clustered in a clade with 2 FASs from Nilaparvata lugens. Furthermore, these 3 FASs are related to cockroach BgFAS and locust LmFAS. After RNA interference-mediated knock-down, most treated insects died at eclosion. In addition, the lifespan of dsFAS1-treated female adults was shorter than that of the dsGFP-injected control, and offspring production decreased. Also, the expression of vitellogenin (Vg) and vitellogenin receptor (VgR) genes decreased. Virgin females dissected at days 2 and 4 post-eclosion showed many matured oocytes in planthoppers treated with dsGFP but not with dsFAS1. These data highlight the importance of LsFAS1 in SBPH, including a role in reproduction.

太阳电池单晶Si片表面制绒已是一项成熟的工艺,但普遍制绒时间较长。为提高制绒效率,本课题研究了较短时间内NaOH/异丙醇(IPA)体系制绒时的温度、时间、溶液组分对绒面的影响,以及制绒前去损伤的优劣。最终实现了,在含2.5%NaOH(质量百分比,下同)和10%IPA的溶液中,80℃恒温处理15 min即可制备出比较均匀的绒面。溶液中加入3%Na2SiO3,效果更佳,反射率最低可达9.5%。并发现去损伤后制绒效果并不理想,同时还研究了表面活性剂1,4-环己二醇(CHX)和十二烷基苯磺酸钠(SDBS)代替异丙醇制绒。研究发现,异丙醇仍然是性价比较好的添加剂。

引用

Dianwang Jishu/Power System Technology 2025年第1期49卷 242-251页

作者： Ai, yu Jia, Yanbing han, Xiaoqing Shanxi Key Laboratory of Power System Operation and Control Taiyuan University of Technology Shanxi Province Taiyuan 030024 China Key Laboratory of Cleaner Intelligent Control on Coal & Electricity Taiyuan University of Technology Ministry of Education Shanxi Province Taiyuan 030024 China

Accurate day-ahead electricity price prediction is the basis for market operation and policy planning, while market disclosure information is essential for electricity price prediction. This paper proposes a combined CNN-GRU deep-learning electricity price prediction model introducing the Self-attention mechanism. Firstly, for the trading process of the Shanxi electricity spot market and the formation mechanism of electricity price before the day, it is proposed to adopt the maximum mutual information coefficient method to extract features from the market disclosed information data such as boundary conditions before the day, to determine the key influencing factors of electricity price and its weight coefficients;and then based on the weighted grey correlation of the history of similar day screening method to generate the historical dataset of electricity price prediction, and to excavate the internal change rule of electricity price and its features;Finally, the CNN-GRU model introducing Self-attention mechanism is used to get the predicted electricity price based on the historical data set. The effectiveness and accuracy of the prediction method proposed in this paper are verified through examples. © 2025 Power System Technology Press. All rights reserved.
