4Exploring Seasonal and Circadian Rhythms in Structural Traits of Field Maize from LiDAR Time Series显示文摘Plant growth rhythm in structural traits is important for better understanding plant response to the ever-changing environment.Terrestrial laser scanning(TLS)is a well-suited tool to study structural rhythm under field conditions.Recent studies have used TLS to describe the structural rhythm of trees,but no consistent patterns have been drawn.Meanwhile,whether TLS can capture structural rhythm in crops is unclear.Here,we aim to explore the seasonal and circadian rhythms in maize structural traits at both the plant and leaf levels from time-series TLS.The seasonal rhythm was studied using TLS data collected at four key growth periods,including jointing,bell-mouthed,heading,and maturity periods.Circadian rhythms were explored by using TLS data acquired around every 2 hours in a whole day under standard and cold stress conditions.Results showed that TLS can quantify the seasonal and circadian rhythm in structural traits at both plant and leaf levels.(1)Leaf inclination angle decreased significantly between the jointing stage and bell-mouthed stage.Leaf azimuth was stable after the jointing stage.(2)Some individual-level structural rhythms(e.g.,azimuth and projected leaf area/PLA)were consistent with leaf-level structural rhythms.(3)The circadian rhythms of some traits(e.g.,PLA)were not consistent under standard and cold stress conditions.(4)Environmental factors showed better correlations with leaf traits under cold stress than standard conditions.Temperature was the most important factor that significantly correlated with all leaf traits except leaf azimuth.This study highlights the potential of time-series TLS in studying outdoor agricultural chronobiology.Shichao Jin Yanjun Su Yongguang Zhang Shilin Song Qing Li Zhonghua Liu Qin Ma Yan Ge LingLi Liu Yanfeng Ding Frédéric Baret Qinghua Guo 2021Plant Phenomics2021,3,1:5

6胆固醇水平与认知功能下降的关系显示文摘尽管血管危险因素可以直接增加阿尔茨海默氏病(AD)的易感性,但胆固醇水平和进行性痴呆之间的直接关联尚无定论。这项前瞻性研究旨在更好地了解这种关联。在基线水平,从上海老龄化研究的参与者中招募了60岁及以上的居民。所有人都接受了体检,包括空腹血脂和APOE基因分型。采集病史,包括血管危险因素(VRFs)。认知功能通过八项测试进行评估,然后由一个专家小组为每个参与者确定与认知功能相关的诊断,包括痴呆。在随访中,确定了基线数据与痴呆进展之间的关系。肥胖、高血压史、糖尿病史、卒中史和冠心病病史被定义为血管危险因素。受试者为1556名起初无痴呆的成年人,平均随访5.2年。在没有血管危险因素的人群中,总胆固醇(TC)和低密度脂蛋白胆固醇(LDL-C)与痴呆的发生呈负相关。此外,LDL-C与AD的发生呈负相关。研究发现,总胆固醇、LDL-C的增加与简易智力状态检查量表得分下降较慢之间存在相关性。在没有VRFs的参与者中,TC每增加1mmol/L会导致所有类型的痴呆风险降低38%(HR,0.62),LDL-C每增加1mmol/L会降低53%的痴呆风险(HR,0.47)。结论:这项中国的研究发现,在没有高血压、糖尿病、卒中或冠心病病史的患者中,总胆固醇和脂蛋白胆固醇升高与痴呆风险的降低有关。龚秋文(译) Ding D 2021中国康复2021,36,9:3

8基于影像表现预测骨关节炎进展显示文摘目前常用X线检查评估骨关节炎(OA)进展,MRI可了解OA初期至晚期关节功能丧失阶段进展规律。最新研究表明,MRI检测到的关节结构异常变化,如软骨缺损和骨髓水肿增加,软骨体积和厚度减少,软骨成分改变等可用于评估OA进展。肥胖、肌肉萎缩、关节内外翻、代谢性疾病、炎症和关节疼痛等临床危险因素及软骨损伤、骨髓水肿、半月板病变、滑膜炎等影像学特征等关节结构因素均与OA进展有关。改善这类危险因素,可减缓疾病进展;利用MRI监测疾病进展,发现新的危险因素,并对危险因素进行干预,有助于阻断OA进展。对处于高危险因素人群进行临床试验研究,可减少试验样本量和随访时间,增强临床试验研究效率。该文主要介绍OA进展的最新流行病学和临床研究证据,以及与OA进展相关的危险因素。徐勤光 韦宋谱 王学宗 丁道芳 庞坚 郑昱新 曹月龙 詹红生 Ding C Zhang Y Hunter D 2013国际骨科学杂志2013,34,2:2

11Influence of Coal Nature and Structure on Ash Size Formation Characteristic and Related Pollutant Emissions During CFB Combustion显示文摘The size distribution of coal particles in a Circulating Fluidized Bed (CFB) boiler plays a crucial role in the complicated combustion, heat exchange and pollutant emissions in such a plat. Therefore, it is fundamental to study the different factors having influence on the size distribution of coal particles. Above all, the coal itself and in particular, the coal combination phenomenon is a very influent factor. In the frame of this work, the coal nature (elementary composition) and coal internal structure (mineral components) are studied in detail. At this intermediary stage, experiments on three typical Chinese coals on a l.5 MWt CFBC pilot plant have been made. Some primary fragmentation tests have also been made in a small lab scale fluidized bed reactor. The results from the hot pilot test show i) the variation of coal ash distributions and other CFB performance data due to the cyclone and the coal characteristics and ii) the variation of desulfurization efficiency with limestone. Whereas the bench scale primary fragmentation test, likely linked to the caking propriety of a coal, does not seem to change considerably the char size distribution.Min QIAN Arnaud BOELLE Philippe JAUD ( Electricite de France Division R&D, 6 quai Watier B.P.49 78401 Chatou, France ) Yongjie NA Qinggang LU Shaolin BAO ding CUI Weihong JIAO Huanming ZHAO (Institute of Engineering Thermophysics, Chinese Academ 2000Journal of Thermal Science2000,9,3:2
