1Estimations of primary production and export production in the South China Sea based on sediment trap experiments显示文摘The results of time series sediment trap experiments in the South China Sea show that particulate organic carbon (POC) fluxes are influenced by the monsoons. The increase of productivity in the northern South China Sea is mainly due to northeast monsoon while in the central South China Sea the influence of southwest monsoon becomes more prominent. The annual primary production and export production calculated based on POC fluxes are 53 0-63 4 and 10 32-12 93 gC·m -2·a -1, respectively. The enhancement of POC flux during monsoon period suggest that higher palaeoproductivity or organic carbon accumulation rate in glacial age in the South China Sea might be the result of strengthening of the monsoons.Jianfang Chen Lianfu Zheng M.

21993~1996年南海中部海洋沉降颗粒通量的季节和年际变化显示文摘通过对南海中部1993~1996年获得的浅层和深层时间系列沉积物捕获器的样品分析,发现了稳定同位素值、颗粒总通量、碳酸盐、生物蛋白石、有机碳、表层初级生产力、浮游有孔虫总通量和属种的分布存在明显的季节性变化,其通量都是在东北季风和西南季风盛行期出现高值,在季风转向期出现低值.浮游有孔虫Globigerinoides sacculifer,G.ruber,Globigerinita glutinata,Neogloboquadrina dutertrei等种的通量和相对百分含量也是在东北季风和西南季风盛行期都出现高值,但Globigerina bulloides,Globorotalia menardii和Pulleniatina obliquiloculata等种则在东北季风盛行期出现高值,分析还发现Globigerinoides sacculifer和Globorotalia menardii等种的通量和百分含量以及有孔虫总通量和碳酸盐通量等从1993到1996年存在下降趋势,而Globigerina,bulloides和Globigerinita glutinata的通量和百分含量以及生物蛋白石通量等在该期间显示为上升趋势,浅层捕获器样品中的碳酸盐和有机碳的通量比深层的高.研究表明海洋沉降通量和浮游有孔虫属种的季节和年际变化主要受与东亚季风相关的表层初级生产力和海洋水文条件变化所控制,深层捕获器样品中的碳酸盐和有机碳的通量低应与碳酸盐溶解作用有关。陈荣华 郑玉龙 WIESNER M G 金海燕 赵庆英 郑连福 成鑫荣 2006海洋学报2006,28,3:17

4H3K27me3表达缺失是散发性和放射相关性恶性外周神经鞘膜瘤的一种高敏感性标志物显示文摘大多数恶性外周神经鞘膜瘤(MPNST)表现为NF1、CD—KN2A及多梳抑制复合体2组成基因——胚胎外胚层发育基因(EED)和Zeste12抑制基因(SUZl2)的共同缺失。EDD和SUZl2的突变导致组蛋白H3第27号位赖氨酸上三甲基化(H3K27me3)无法进行,导致多梳抑制复合体2抑制性同源盒主调控因子转录活性异常。因此,作者探讨抗H3K27me3单克隆抗体C36811作为MPNST免疫组化标志物的作用。Prieto-Granada C N Wiesner T Messina J L 胡舜 余英豪(审校) 2016临床与实验病理学杂志2016,32,7:9
5南海北部和中部硅藻通量季节性变化及其对季风气候的响应显示文摘通过对南海北部和中部两套时间序列沉积物捕获器中的颗粒物样品进行硅藻分析,揭示了南海北部和中部硅藻通量的季节变化规律及其区域差异和各自对东亚季风气候的响应。研究表明在南海北部和中部海域,硅藻通量可以在一定程度上指示海洋初级生产力水平,其中南海北部硅藻通量明显低于中部,这可能与北部颗粒物样品采集期间发生的El Ni o事件有关;南海北部和中部硅藻通量均存在明显的季节性变化规律,其中东亚冬季风对南海北部海域硅藻的生长有着显著影响,而南海中部则受夏季西南季风的影响更为强烈;南海北部深层硅藻通量高于浅层,这表明南海北部可能存在较强的深层流作用。冉莉华 郑玉龙 陈建芳 陈荣华 郑连福 WIESNER Martin-G 2011海洋学报2011,33,5:7
62009—2010年南海北部浮游有孔虫通量和稳定同位素季节变化及其对东亚季风的响应显示文摘通过对南海北部2009—2010年获得的浅层、中层和深层时间系列沉积物捕获器的样品分析,发现浮游有孔虫总通量和主要属种Globigerinoidesruber,Globigerinoidessacculifer,Pulleniatinaobliquiloculata和Neogloboquadrinadutertrei的通量和百分含量存在明显的季节性变化,在东北季风和西南季风盛行期出现高值,特别在冬季风期间高值明显,在季风间歇期出现低值,展示出'双峰型'通量模式。浮游有孔虫通量与颗粒总通量、有机碳通量、总碳通量、总氮通量、碳酸钙通量和蛋白石通量变化一致,随叶绿素a浓度和风速大小变化而改变,表明南海北部生源颗粒通量主要受季风影响的表层生产力所控制。浮游有孔虫壳体氧同位素与表层海水温度的季节变化相吻合。壳体δ18 O主要受海水温度变化的影响,不同深度属种的δ18 O变化反映了上层海水温度梯度。此外,壳体碳同位素值总体上在东亚季风强盛期低、季风间期高,与表层海水中叶绿素a浓度和海表风速的变化趋势相反,说明浮游有孔虫δ13 C值反映了水体营养和表层生产力的变化。王小华 陈荣华 赵庆英 陈建芳 冉莉华 Wiesner M G 2014海洋地质与第四纪地质2014,34,1:7
7南海若干古生产力替代指标探讨显示文摘沉积记录中的古环境信息,是经过各种复杂的生物地球化学过程改造后的信号,因而是不完整的,有些甚至可能是被歪曲的。通过表层沉积有机碳、生物硅和色素对上层海洋的响应,对南海古生产力替代指标的可靠性及其影响因素作出初步评估。尽管南海海洋生产力较低,生源通量以小颗粒为主(沉降速率慢),侧向漂移明显,且不易形成低氧条件,使有机碳的保存效率比较低,影响了沉积有机碳作为古生产力替代指标的可靠性,但南海表层沉积有机碳含量在大的时空尺度上仍然能反映上升流高生产力区状况,说明沉积记录(几十至几百年时间尺度)对小尺度(自季至年)上的'细节'差异可以进行'平滑'。总的来说,沉积有机碳是比较好的古生产力指标,但对于寡营养、生物群落结构时空变化大、碳酸盐溶解和陆源稀释影响明显的南海,将绿素和生物硅含量作为古生产力替代指标时应该更加慎重。陈建芳 李宏亮 金海燕 陈法锦 M G WIESNER 郑连福 2010海洋学研究2010,28,1:6

9The Globalization of Traditional Medicines: Perspectives Related to the European Union Regulatory Environment显示文摘In the Member States of the European Union (EU), a harmonized legislation on medicinal products has been enforced, which specifically defines herbal medicinal products and traditional herbal medicinal products. The scope was to create a regulatory environment that takes into account the particular characteristics of herbal medicinal products. The harmonization of standards is intended to harmonize assessment and facilitate access to the market in different Member States. The standards defined by the EU herbal monographs of the Committee on Herbal Medicinal Products (HMPC) and the quality requirements laid down in the European Pharmacopoeia represent an excellent model of multinational harmonization of the regulatory environment for herbal and traditional medicines. It has also been demonstrated that this framework is at least partially applicable for herbal and traditional medicines from traditional Chinese medicine (TCM) to gain access to the EU market. Moreover, the HMPC provides specific guidance documents and pilot projects on monographs on the safety and efficacy of Chinese herbal drugs. In the European Pharmacopoeia, the number of quality monographs of herbal drugs with an origin in TCM is continuously growing. These developments indicate that globalization of traditional medicines is an ongoing process. Communication and cooperation between regulators, the scientific community, and interested stakeholders will set the stage for the convergence of diverse regulatory environments. This will contribute to worldwide availability of traditional medicines based on appropriate standards.Werner Knoess Jacqueline Wiesner 2019Engineering2019,5,1:3

15南海生源物质通量与生物泵组成的初步解析显示文摘海洋'生物泵'是海洋去除大气CO2的一种机制。'生物泵'的强度可以用真光层以下水柱生源颗粒物质的输出通量来表示,常用的方法有放射性同位素示踪法和沉积物捕获器法。前者获得的是海洋某一时段、某一站位的颗粒物质通量;而后者除了获取短时间尺度(十几天)至年际尺度的物质通量以外,还可以利用收集到的样品开展地球化学、微体古生物学等分析,从而进一步推知生物泵的组成。迄今为止,利用沉积物捕获器开展南海生物地球化学通量研究已有20余年,已经有诸多成果发表。本文在总结已发表成果和笔者部分未发表数据基础上,对于南海北部海域生物地球化学通量变化、组成特征及其季节变化进行了回顾和总结,并与利用放射性同位素234Th/238U不平衡法获得的结果进行了比较。在此基础上,对南海生物泵结构和调控因子作了初步的分析探讨,发现,南海'碳酸盐泵'和'硅酸盐泵'具有同等重要的作用。指出,若要全面了解南海生物泵的时空变化及其调控机制,需要开展点(锚系潜标与浮标)、线(船基断面调查和过程研究)、面(时间序列的遥感资料)结合的综合观测和研究。陈建芳 Wiesner M.G. 李宏亮 冉莉华 张静静 孙麟 2015矿物岩石地球化学通报2015,34,5:2
