Dear Editor,Since the first plant receptor-like kinase(RLK)gene ZmPK1 was cloned from Zea mays in 1990(Walker and zhang,1990),this large gene family has been extensively studied and shown to play crucial roles in growth,development,and immunity(Tang et al.,2017).RLKs are widespread in the plant ***,biological functions of most RLKs remain largely elusive(Dievart et al.,2020).Given RLKs share a conserved monophyletic RLK/Pelle kinase domain,RLKs in several model plants are classified into distinct families by extracellular domains(Shiu and Bleecker,2001).However,independent domain shuffling in specific lineages drives the origin of novel families,which raises a question what is the landscape of RLKs across the entire plant kingdom?Previously,sequence-homology-based methods have been widely used for RLK identification and classification,which might miss distantly related proteins with similar structures and potential novel families not mentioned in the *** academic community urgently requires a dedicated database for a systematic overview of the RLK gene family,providing data support for in-depth research on RLK ***,we used a topology-based method to accurately isolate the RLKomes from *** obtained RLKomes were further classified into(sub)families based on extracellular *** con-structed a comprehensively curated plant RLK database(https://***/rlkdb),which contains valuable re-sources for investigating the origin and evolution of the RLK fam-ily and multiple online tools for personalized analysis.

该研究的目的是探究小麦肽对乙醇造成的胃黏膜损伤的保护作用及其机制。使用小麦肽进行处理后,乙醇诱导小鼠胃黏膜损伤模型和人胃黏膜上皮细胞(human gastric mucosal epithelial cell,GES-1)细胞损伤模型,观察小鼠体重变化和胃组织损伤状况,评估氧化应激、炎症和自噬相关蛋白表达水平。小麦肽预处理显著改善了乙醇诱导的小鼠体重降低,提高了胃组织和GES-1细胞内抗氧化酶活力和一氧化氮(NO)含量,减少脂质过氧化发生。病理组织切片显示,小麦肽预处理后,胃组织损伤显著减少。此外,小麦肽降低了组织内促炎因子表达,并通过抑制GES-1细胞中PI3K/AKT/mTOR通路激活,提高了LC3-Ⅱ蛋白表达。小麦肽可以通过调节抗氧化能力和促炎因子表达,抑制PI3K/mTOR通路激活等方式,改善乙醇诱导的胃黏膜损伤。

SAR图像测量地球物理参数，实现定量遥感应用，对辐射定标精度有严格要求，因此需要对SAR卫星进行辐射定标精度验证。通过雷达方程推算出雷达散射截面积、定标常数与图像DN值三者之间的关系，并利用宁夏中卫定标场有源定标器及其SAR图像做定标验证实验。实验结果表明，高分三号02星数据绝对辐射定标精度较高，其中积分法辐射定标精度为0.65 dB,而峰值法定标精度为0.57 dB;海丝1号卫星数据辐射定标精度为1～2 dB,计算定标常数时保持相同波位可有效提高定标常数的稳定性。

Journal of Thermal Science 2017年第6期26卷 545-551页

作者： zhang yin WEI zhiyuan zhang yinping WANG Xin College of Architecture and Environment Sichuan University Department of Building Science Tsinghua University

Urban heating in northern China accounts for 40% of total building energy usage. In central heating systems, heat is often transferred from heat source to users by the heat network where several heat exchangers are installed at heat source, substations and terminals respectively. For given overall heating capacity and heat source tempera- tore, increasing the terminal fluid temperature is an effective way to improve the thermal performance of such cascade heat exchange network for energy saving. In this paper, the mathematical optimization model of the cas- cade heat exchange network with three-stage heat exchangers in series is established. Aim at maximizing the cold fluid temperature for given hot fluid temperature and overall heating capacity, the optimal heat exchange area dis- tribution and the medium fluids＇ flow rates arc determined through inverse problem and variation method. The preliminary results show that the heat exchange areas should be distributed equally for each heat exchanger. It al- so indicates that in order to improve the thermal performance of the whole system, more heat exchange areas should be allocated to the heat exchanger whore flow rate difference between two fluids is relatively small. This work is important for guiding the optimization design of practical cascade heating systems.
