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.

气体膜分离法是从气流中分离二氧化碳(CO2)的最有前途的技术之一。例如,采用该技术对燃烧过程中的烟气进行处理,以达到CO2 捕集和封存的目的。聚环氧乙烷嵌段共聚物能够很好地应用于膜分离技术,如Pebax® 或PolyActive™。本文采用PolyActive™ 作为复合薄膜的选择层。在环境温度下,当CO2/N2 选择性超过55 时,这种薄膜的CO2渗透率高达4 m3(STP)·m−2·h−1·bar−1(注:1bar=105 Pa)。这种薄膜可以按照中试规模进行生产放大,而且可以设计成不同的平面膜组件。采用单一气体渗透数据作为唯一的实验输入而开发出的仿真工具可以准确预测这种膜组件的性能。在不同的中试研究中,我们利用烟气和沼气作为原料气流,反复检测这些膜和膜组件的性能。PolyActive™ 在检测中显示出了稳定的分离性能,表明PolyActive™ 非常适用于作为膜材料进行工业规模气体处理。
