采集辽河流域浑河、太子河干流及大伙房水库共56个站点的表层沉积物样品,根据相平衡分配法的修正模型建立辽河流域沉积物重金属质量基准(Cu、Pb、Zn、Cd的SQC(基于CCC)分别为75.26 μg/g、25.72 μg/g、255.96 μg/g、2.52 μg/g),依据重金属急、慢性生物毒性风险确定辽河流域沉积物重金属质量三级标准,并创建沉积物质量风险评估方法——沉积物污染指数法(SPI),对辽河流域水环境进行沉积物质量风险评估,评估结果显示:浑河干流中下游、太子河中上游及大伙房水库库中、库尾处的沉积物质量状况为中风险,此沉积物重金属污染状况使长期生活在其中的底栖生物受到轻微重金属慢性毒性影响,其中浑河中游红透山铜矿处和细河上游沈阳工业区的沉积物质量风险极高。

笔者设计并实现了高通量多羽流脉冲激光沉积 (MPPLD) 系统,而且与传统的高通量薄膜材料合成技术进行了比较。目前大多数组合式脉冲激光沉积 (PLD) 系统为了使沉积的薄膜厚度均匀而采用掩膜法多层薄膜沉积和沉积后退火的工艺,MPPLD则同时利用了多个PLD羽流的方向性和沉积速率的空间变化,在一个衬底上直接沉积不同成分的化合物以形成薄膜材料库

The central dogma of biology holds that the transcription of DNA into RNA and the translation of RNA into proteins forms the primary axis of biological activity [1]. Following major advances in the description of the complex glycan and lipid chains that are added onto these basic building blocks, the glycome and lipidome have recently been added to this doctrine as an exciting new extension named the ‘‘paracentral dogma” [2]. However, it has been pointed out that biological systems can include many layers, which are described in modern omics technology platforms relating to both cell-intrinsic and cell-extrinsic layers of control, including metabolomic, microbiomic, immunological, epigenomic, epitranscriptomic, proteomic and phosphoproteomic layers [3].
It is well known that stem and progenitor cells have a metabolism that is based on glycolysis and glutaminolysis [4]. Although this provides less energy to the cell than oxidative phosphorylation, it suffices for these cells’ needs, since such cells are generally relatively quiescent and normally suppress energy-intensive processes such as genome duplication and transcription. Moreover, it has been shown that the high intracellular lactate levels involved in such states not only inhibits the key gatekeeper enzymes of oxidative phosphorylation (i.e., pyruvate dehydrogenase and carnitine palmitoyl acyltransferase) but also actually covalently modifies them by lactylation in order to maintain this inhibited metabolic–epigenomic state [5]. In addition, intermediate metabolism and nutrients are the source of the very extensive library of post-translational modifications to DNA, RNA, and proteins, as well as supplying cellular energy for many of the required reactions. Hence, the metabolic state locks in and reinforces the epigenomic state, and the metabolome and epigenome thereby play mutually reinforcing roles. This self-reinforcing coordination explains why it is so difficult to generate induced pluripotent cells and is a contributory explanation for why the described protocols typically have such low cellular yields.
These concepts become even more important when it is considered that cancer cells are de-differentiated, similarly rely on glycolysis and glutaminolysis, and are similarly metabolically–epigenomically–genomically synchronized. The disruption of this metabolic system is a key focus of mechanistic cancer research.
These important considerations imply that the descriptive and predictive power of the newly described ‘‘paracentral dogma” of biology may be usefully and meaningfully extended by including the metabolome, along with the genome, transcriptome, proteome, glycome, and lipidome, to describe cell-intrinsic regulation—not only in terms of another omics analytical layer but also as a fully predictive and interactive partner in the symphonic-like multilayer coordination that evidently comprises cellular regulatory layering.

仿生学(模仿生物特殊本领的学科) 以及合成生物学,将和过去50年的硅芯片一样与工程开发、工业发展产生紧密联系。化学工业已经将白色生物技术应用于新工艺、新材料和资源的可持续利用中。合成生物学也已经应用到第二代生物燃料的发展中,并利用特制的微生物或生物制催化剂获取太阳能。而仿生学在制药、处理工程以及DNA存储领域的市场潜力是巨大的。这些研究将给生物学带来新思考。生物工程将和今天的数字化技术一样驱动创新。本文讨论了生物工程,特别是碳基生物燃料的应用和细胞饰变的技术与风险。大数据、分析学和海量存储将是未来的发展方向。虽然合成生物学在未来50年将和当今的数字化一样普遍且具有革新能力,但是目前它的应用和影响力还处在初级阶段。本文采用了将生物工程发展分为五个阶段(DNA分析、生物回路、最小基因组、原始细胞、异源生物学)的普遍分类方法,阐述了其对安全与保障、工业发展以及生物工程和生物技术作为跨学科领域发展的影响,同时讨论了伦理问题及公众对仿生学和合成生物学结果的公众讨论的重要性

Most human-secreted and membrane-bound proteins have covalently attached oligosaccharide chains, or glycans. Glycosylation influences the physical and chemical properties of proteins, as well as their biological functions. Unsurprisingly, alterations in protein glycosylation have been implicated in a growing number of human diseases, and glycans are increasingly being considered as potential therapeutic targets, an essential part of therapeutics, and biomarkers. Although glycosylation pathways are biochemically well-studied, little is known about the networks of genes that guide the cell- and tissue-specific regulation of these biochemical reactions in humans in vivo. The lack of a detailed understanding of the mechanisms regulating glycome variation and linking the glycome to human health and disease is slowing progress in clinical applications of human glycobiology. Two of the tools that can provide much sought-after knowledge of human in vivo glycobiology are human genetics and genomics, which offer a powerful data-driven agnostic approach for dissecting the biology of complex traits. This review summarizes the current state of human populational glycogenomics. In Section 1, we provide a brief overview of the N-glycan's structural organization, and in Section 2, we give a description of the major blood plasma glycoproteins. Next, in Section 3, we summarize, systemize, and generalize the results from current N-glycosylation genome-wide association studies (GWASs) that provide novel knowledge of the genetic regulation of the populational variation of glycosylation. Until now, such studies have been limited to an analysis of the human blood plasma N-glycome and the N-glycosylation of immunoglobulin G and transferrin. While these three glycomes make up a rather limited set compared with the enormous multitude of glycomes of different tissues and glycoproteins, the study of these three does allow for powerful analysis and generalization. Finally, in Section 4, we turn to genes in the established loci, paying particular attention to genes with strong support in Section 5. At the end of the review, in Sections 6 and 7, we describe special cases of interest in light of new discoveries, focusing on possible mechanisms of action and biological targets of genetic variation that have been implicated in human protein N-glycosylation.
