The Lie algebra sl_(2)(C)may be regarded in a natural way as a subalgebra of the infinite-dimensional Virasoro Lie algebra,so it is natural to consider connections between the representation theory of the two *** this paper,we explore the restriction to sl_(2)(C)of certain induced modules for the Virasoro ***,we consider Virasoro modules induced from so-called polynomial subalgebras,and we show that the restriction of these modules results in twisted versions of familiar modules such as Verma modules and Whittaker modules.

While self-assembled monolayers(SAMs)of aromatic thiolates are frequently used in a wide range of applications,their formation is often hampered by the low solubilities of their *** we introduce the 3,4-dimethoxybenzyl group as a protective group for the thiol moiety,which increases the solubility and stability of the precursor,but becomes cleaved off during monolayer formation,especially at elevated temperature(60°C)and in presence of protons(trifluoroacetic acid).For a series of substituted terphenylthiols as model systems,it could be demonstrated by using ellipsometry,infrared-reflection absorption spectroscopy,and scanning-tunneling microscopy that the resulting SAMs have the same structure and quality as the ones obtained from the respective unprotected *** protective group has the additional advantage to be stable under Pdcatalyzed C–C bond formation reaction conditions,facilitating the syntheses of the respective precursors.

通过对菲律宾皮纳图博(Pinatubo)火山1991年6月爆发前后南海表层沉积物及沉降颗粒物中的硅藻丰度及群落组成进行分析,试图揭示皮纳图博火山爆发对南海硅藻生长的影响。研究发现,火山爆发后南海沉积物中硅藻相对丰度显著减少,原因主要在于皮纳图博火山喷发物大量沉积于南海深海,显著提高了南海沉积速率,同时稀释了沉积物中生源物质的含量。进一步对火山爆发前后同期南海中部深海沉降颗粒物开展研究发现,火山爆发次年同期沉降颗粒物总通量以及生物硅通量明显增加,而硅藻及其他硅质生物相对丰度和通量均显著降低,其中硅藻相对丰度从2.20×10^(8)枚·g^(-1)降到5.48×10^(7)枚·g^(-1),通量从2.90×10^(7)枚·m^(-2)·d^(-1)降到8.57×10^(6)枚·m^(-2)·d^(-1)。1年后的南海中部深海沉降颗粒物中仍然有大量火山玻璃的存在,可能是导致湿化学法测量生物硅含量明显增加的主要原因,而硅藻乃至所有硅质生物通量及丰度的显著降低可能与火山灰沉降的负面影响有关,也可能与1991年厄尔尼诺对南海海洋环境的影响有关。总之,1991年6月皮纳图博火山爆发后南海的沉积物硅藻及沉降颗粒物硅藻丰度都出现了显著降低,但具体的环境调控机制仍有待进一步深入研究。

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.

The synaptonemal complex （SC） is an evolutionarily well-conserved structure that mediates chromosome synapsis during prophase of the first meiotic division. Although its structure is conserved, the characterized protein components in the current metazoan meiosis model systems （Drosophila melanogaster, Caenorhabditis elegans, and Mus musculus） show no sequence homology, challenging the question of a single evolutionary origin of the SC. However, our recent studies revealed the monophyletic origin of the mammalian SC protein components. Many of them being ancient in Metazoa and already present in the cnidarian Hydra. Remarkably, a comparison between different model systems disclosed a great similarity between the SC components of Hydra and mammals while the proteins of the ecdysozoan systems （D. rnelanogaster and C. elegans） differ significantly. In this review, we introduce the basal-branching metazoan species Hydra as a potential novel invertebrate model system for meiosis research and particularly for the investigation of SC evolution, function and assembly. Also, available methods for SC research in Hydra are summarized.
