Rechargeable metal-ion batteries, such as lithium-ion batteries(LIBs) and sodium-ion batteries(SIBs),have raised more attention because of the large demand for energy storage solutions. Undoubtedly, electrode materials and electrolytes are key parts of batteries, exhibiting critical influence on the reversible capacity and span life of the metal-ion battery. Nonetheless, researchers commonly express concerns regarding the stability of both electrodes and electrolytes. Given its commendable stability attributes,high-entropy materials have garnered widespread acclaim and have been applied in many fields since their inception, notably in energy storage. However, while certain high-entropy designs have achieved substantial breakthroughs, some have failed to meet anticipated outcomes within the high energy density energy storage materials. Moreover, there is a lack of comprehensive summary research on the corresponding mechanisms and design principles of high-entropy designs. This review examines the current high-entropy designs for cathodes, anodes, and electrolytes, aiming to summarize the design principle,potential mechanisms, and electrochemical performance. We focus on their structural characteristics,interface characteristics, and prospective development trends. At last, we provide a fair evaluation along-side succinct development suggestions.

Genetic variation in ZmVPP1 contributes to drought tolerance in maize seedlings

作者： Xianglan Wang Hongwei Wang shengxue Liu Ali Ferjani Jiansheng Li Jianbing yan Xiaohong yang Feng Qin Key Laboratory of Plant Molecular Physiology Institute of BotanyChinese Academy of Sciences Graduate University of the Chinese Academy of Sciences Department of Biology Tokyo Gakugei University National Maize Improvement Center of ChinaChina Agricultural University National Key Laboratory of Crop Genetic Improvement Huazhong Agricultural University

Maize production is threatened by drought stress worldwide. Identification of the genetic components underlying drought tolerance in maize is of great importance. Here,we report a genome-wide association study(GWAS) of maize drought tolerance at the seedling stage that identified 83 genetic variations which were resolved to 42 candidate genes. The peak signal of GWAS uncovered that the natural variation in ZmVPP1,encoding a vacuolar-type H+-pyrophosphatase,most significantly contributes to the trait. Further analysis found that a 366-bp insertion in the promoter,containing three MYB cis-elements,confers drought-inducible expression of Zm VPP1 in drought-tolerant genotypes. Introgression the tolerant allele of ZmVPP1 into drought sensitive genetic background greatly improved seedling drought stress tolerance. Transgenic maize with enhanced ZmVPP1 expression exhibits improved drought tolerance,most likely due to enhanced photosynthetic efficiency and root development. Taken together,this research provides important genetic insights into the natural variation of maize drought tolerance. The identified loci/genes can serve as direct targets for both genetic engineering and selection for the trait improvement of maize.

Salidroside alleviates ferroptosis of retinal ganglion cells in db/db mice

引用

Food Science and Human Wellness 2024年

作者： Wenqiang Liu Anqi Liu Yufei Wang shengxue Yu Chuang Feng Wanpeng Liu yan Fang Jing Li Hongdan Yu Jiayou Liu Wenjuan Wang Jiayuan Ding Pan Lü Lipan Zhao Linqin Luo Xuezheng Liu Zhongfu Zuo Department of Anatomy， School of Basic Medicine， Jinzhou Medical University Liaoning Key Laboratory of Diabetic Cognitive and Perceptive Dysfunction， Jinzhou Medical University Tianjin Medical University Cancer Institute and Hospital， National Clinical Research Center for Cancer Xi'an Jiaotong University College of Medicine

Salidroside (Sal)， is one of the important food supplements from the traditional Chinese medicine Integripetal Rhodiola herb， encapsulating significant anti-oxidative stress， anti-ferroptosis， and neuroprotective attributes. Notwithstanding these latent virtues， the ramifications of Sal on retinal ganglion cells (RGCs) impairment during the incipient stages of diabetic retinopathy (DR) remain equivocal. The purpose of this study was to investigate inhibitory effect of Sal on ferroptosis of RGCs in db/db mice. Within the research conducted， Sal was administered via gavage， and observations were made eight weeks post-treatment. Retinal samples were collected for analysis. The results evidenced that Sal ameliorated blood glucose levels， attenuated RGCs destruction， and augmented visual functionality in db/db mice. Additionally， Sal exerted an anti-ferroptosis impact on the RGCs in the db/db mice. Successive discoveries have outlined the involvement of the HIF-1α/HO-1 signaling pathway in this protective mechanism. Ferroptosis of RGCs has a contributory effect on the development of DR， in part through the HIF-1α/HO-1 pathway. Intriguingly， Sal reversed the alterations in the HIF-1α/HO-1 pathway in db/db mice and displayed prospective advantageous effects on DR. Sal mitigated RGCs ferroptosis by reducing blood sugar and impeding the HIF-1α/HO-1 signaling pathway， thereby improving diabetic retinopathy. Thus， Sal shows potential for use as a pharmaceutical and nutraceutical for DR.

为揭示岩心渗透率对微生物驱油效果的影响规律,通过物理模拟的方法研究了不同渗透率条件下微生物在岩心中的生长代谢及驱油效果,并采用扫描电镜分析了岩心内部菌体的分布。研究表明,微生物激活生长以后能够产生驱油作用,渗透率为500×10^(-3)μm^2时微生物驱提高采收率最大(达6.6%),渗透率过高(>1500×10^(-3)μm^2)或过低(<100×10^(-3)μm^2)时微生物驱油效果均变差。渗透率过低时,孔吼半径较小,微生物无法通过孔吼进入岩心内部;渗透率过高时,菌体随产出液驱出,不能在岩心内部产生滞留作用。渗透率在100×10^(-3)~1500×10^(-3)μm^2范围内有利于微生物的生长吸附和滞留作用,此渗透率范围可以作为微生物驱油油藏渗透率筛选的依据。
