In a recent paper published in Nature,Li et *** that resistance to stimulator of interferon genes(STING)monotherapy in solid tumors is attributable to the unexpected surge of IL-35-producing regulatory B(Breg)cells that impair NK-cell cytotoxicity[1].They depict STING-induced Breg-NK-cell crosstalk and propose that combining the STING agonist 2'3'cyclic GMP-AMP(cGAMP)with anti-IL-35 blockade is a promising strategy to overcome tumor immunosuppression,especially in pancreatic cancers[1].

引用

Signal Transduction and Targeted Therapy 2023年第6期8卷 2437-2439页

In two recently published papers in Nature,^(1,2)Logan Walsh and colleagues utilized imaging mass cytometry(IMC)to create comprehensive single-cell spatial landscapes of the tumor immune microenvironment(TIME)in lung tumors from 416 lung adenocarcinoma(LUAD)patients,as well as brain tumors from 139 high-grade glioma and 46 brain metastasis(BrM)*** conducting a thorough analysis to characterize cellular spatial interactions and neighborhood patterns,and correlating these spatial features with clinical outcomes(Fig.1),the researchers gained novel insights into the complexities of tumoral ***,they identified two sets of clinically relevant predictive immune markers that could be used to assist in guiding clinical decisions.

LiNi_(0.8)Co_(0.15)Al_(0.05)O_(2)@Cr_(2)O_(5)composite electrode combines the high rate-capability characteristics of NCA with the stability of Cr_(2)O_(5),playing a synergistic role in improving the cyclic stability,initial discharge capacity and the security of low cut-off voltage(2.0 V).When the mass ratio of Cr_(2)O_(5)in NCA is 45%(mass),the capacity retention rate increases from 58.5% without Cr_(2)O_(5)to 69.3% in the range of 2.0-4.3 *** initial discharge capacity of NCA@Cr_(2)O_(5)composite material is 211.4 mA·h·g^(-1),its first coulombic efficiency is 94.2%,and the charging capacity remains approximately constant when mixed with 15%(mass)Cr_(2)O_(5).The reason for the improvement of the initial charge-discharge efficiency(ICDE)was *** and cyclic voltammetry analysis reveal more detailed reasons of the observed *** with NCA cathode material,the NCA@Cr_(2)O_(5)composite material can provide not only additional stable sites and channels for Li^(+)insertion/extraction to make up for the loss of active Li^(+)sites and prevent the accumulation of Li+in the circulation process,but also protect the NCA electrode from the corrosion of the electrolyte decomposition by the Cr_(2)O_(5)nanoparticles adhering to NCA interface.

由于锂离子电池内部电化学反应的复杂性以及外部工作环境的不确定性,难以对电池SOH(健康状态)进行准确估算。为了提高SOH的估算精度,提出一种基于XGBoost算法的锂离子电池健康状态估算方法。首先,利用Matplotlib对锂离子电池数据进行分析,并提取平均电压、电压差、电流差和温度差等特征量来描述电池的老化过程。然后,利用XGBoost算法建立估算模型,对电池SOH进行智能估算。实验结果表明:与线性回归、随机森林、支持向量机、K近邻算法这4种回归算法相比,所提方法的估算精度和泛化能力更优,并且可将估算误差控制在±0.4%左右。

体育课程思政是落实立德树人的本质要求。体育课程思政建设是我国高校体育工作落实立德树人根本任务的一个重要途径。该文通过文献资料法、逻辑分析法和访谈法,研究发现:目前高校存在体育课程思政建设的保障机制不完善;相关领域的研究多数处于学理层面,缺少立足于实际的可行性方案;高校体育教师思政素养有待提高,积极性有待调动等。针对存在的问题,提出高校体育课程思政建设突破路径:建立健全的保障机制,保障课程思政育人效果见功见效;理论层面指导与实践层面相结合;注重对体育教师的课程思政育人能力的培养。希望该文为深化高校体育课程思政建设提供一些参考。
