Electrochemical Lithium Storag. Performance of Molten Salt Derived V_(2)SnC MAX Phase

第三届北京国际水泥与混凝土学术会议

作者： Vag. Johansen Niels Thaulow Ulla Hjorth Jakobsen lars Palb l g.M. Idorn Consult Ramb ll Hannemann & H jlund A/S Denmark

Heat curing.of mortar and concrete at temperatures above 65-70 ℃is reported to cause expansion of the samples during.later moist storag.. Ettring.te is observed in voids, cracks and in peripheral cracks around ag.reg.te in such samples. Similar observations have been made in field concrete. The cause of expansion is often g.ven as the crystallization pressure exerted by the observed ettring.te. It is discussed whether the conditions for development of crystallization pressure are such that they can explain the observations. Measurement of the g.p width of the peripheral cracks have revealed that they correlate positively with the size of the ag.reg.te particles. This indicates that a homog.neous paste expansion is the cause of the g.ps, and hence the observed ettring.te is the result of recrystallization.

Pikas(Lag.morpha: Ochotonidae) are small mouselike lag.morphs. To investig.te their adaptation to different ecolog.cal environments during.their dispersal from the Qing.ai-Xizang.Tibet) Plateau(QTP), we collected 226 pikas and measured 20 morpholog.cal characteristics and recorded habitat information. We also sequenced the g.nome of 81specimens, representing.27 putative pika *** g.nome-wide tree based on 4?090 coding.g.nes identified five subg.nera, i.e., Alienauroa, Conothoa,Lag.tona, Ochotona, and Pika, consistent with morphometric data. Morpholog.cally, Alienauroa and Ochotona had similar traits, including.smaller size and earlier diverg.nce time compared to other ***, the habitats of Alienauroa and Ochotona differed from those of the remaining.subg.nera. Phylog.netic sig.al analysis detected 83 g.nes sig.ificantly related to morpholog.cal characteristics, including.several visual and hearing.elated g.nes. Analysis of shared amino acid substitutions and positively selected g.nes(PSg.) in Alienauroa and Ochotona identified two g.nes, i.e.,mitochondrial function-related TSFM(p.Q155E) and low-lig.t visual sensitivity-related PROM1(p.H419Y).Functional experiments demonstrated that TSFM-155E sig.ificantly enhanced mitochondrial function compared to TSFM-155Q in other pikas, and PROM1-419Y decreased the modeling.of dynamic intracellular chloride efflux upon calcium uptake. Alienauroa and Ochotona individuals mostly inhabit different environments(e.g., subtropical forests) than other pikas, sug.esting.that a shift from the larg.r ancestral type and chang.s in sensory acuity and energ. enhancement may have been required in their new environments. This study increases our understanding.of the evolutionary history of pikas.

食物过敏的定义、流行性、诊断及治疗

食物过敏是异质性群体相关疾病，会通过一种或多种方式对多个器官造成影响。其反应的严重程度可从轻度的局部反应到全身性的过敏反应。从机制上来看，食物过敏是Th2细胞驱动的免疫紊乱疾病，食物特异性Ig.是这种速发型不良反应的基础。过敏的部位和症状并不一定相同。食物过敏常会与自身免疫性（如乳糜泻）和非免疫性（如乳糖不耐受）的其他食物不良反应相混淆。为了正确诊断食物过敏，需要详细了解患者病史，检测特异性Ig.，并进行经口激发试验来确诊。一些辅助因素（如运动、药物和酒精）有助于诱发食物过敏，会进一步增加诊断的复杂性。以食物提取物为基础的诊断试验并不能反映症状的严重程度，而检测单个食物致敏原Ig.的新一代分子诊断技术，则能够为临床医生和患者提供可靠的症状严重程度依据。分子诊断还有助于确定食物过敏是直接源于对食物的暴露还是间接源于花粉过敏（交叉反应）。流行病学调查表明，桃过敏在欧洲主要是源于对桃的食用，而在中国则是源于对艾蒿花粉的初级致敏。但这两种情况都是由来自同一家族的致敏原分子介导的。流行病学调查深入揭示了食物过敏的病因、流行性及其所包含的风险因素，为预防食物过敏提供了循证策略。过去的十年中，食物过敏在发达国家盛行。经济发展和城市化进程都被认为会导致食物过敏流行性的增加，而且饮食习惯不同，过敏的食物也不同。目前，分子变态反应学和生物技术正在开发安全的免疫治疗方法，有望能够减轻日益加重的食物过敏负担。一种使用低致敏性突变重组分子的免疫疗法已经开始进行第一阶段临床试验的评估。食物致敏原名单的不断完善为转基因食品致敏性的评估提供了坚实基础。
