Traumatic brain injury(TBI)is a public health problem with an undue economic burden that impacts nearly every age,ethnic,and gender group across the globe(Capizzi et al.,2020).TBIs are often sustained during a dynamic range of exposures to energetic environmental forces and as such outcomes are typically heterogeneous regarding severity and pathology(Capizzi et al.,2020).

电压门控Ca2+通道是由多个亚基组成的膜蛋白,其分布广泛,生理功能极为重要,可被众多蛋白和信号传导通路调节。本综述重点介绍蛋白质水解对电压门控Ca2+通道的调节作用及其生理功能。Ca2+通道的主亚基Cavα1可被蛋白质水解,从而调控Ca2+通道的功能和降解,影响基因表达和细胞兴奋性。根据其组织分布,l类Ca2+通道有两种水解模式:在心脏和骨骼肌,Cavα1的羧基末端被水解后与剩余的羧基端结合,抑制Ca2+通道电流。这种自身抑制可被体内分泌的肾上腺素解除,引发心肌和骨骼肌Ca2+电流大量增加,在"打或逃"之类的应激反应中起重要作用,Cavα1羧基末端水解在大脑也存在,并可能是由calpain蛋白质水解酶催化;在某些大脑区域,Cavα1的整个羧基端可被水解并迁移至细胞核,起到转录因子的作用。P/Q类Ca2+通道Cavα1的羧基末端也可被水解,并迁移到细胞核。许多基因突变产生截断型P/QCavα1,而这些截断型Cavα1可严重影响正常Ca2+通道的功能,导致人类的疾病。截断型N类Ca2+通道Cavα1可通过诱变产生,影响正常通道的表达。新型Ca2+通道水解新模式可能是未来Ca2+通道研究中一个重要的探索方向。

Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol（1,6-HDO） with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments（LCAs）.Strategy A was found to be the most favorable both economically（USRDSCHARDOLLAR3,402/ton） and environmentally（-26.9 kg CO2eq.）. This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.
