In this study, the key drivers of sustainability commitment, green supply chain management, big data integration and green human resource practice are explored, and the impact of these sustainable capabilities on the environmental and financial performance of banks is also elaborated. In addition, the influence of green management practices on integrating big data technology into operations is presented. As for the concept of dynamic ability, it has been used to recommend and empirically test conceptual models. Data were collected through a self-administrated survey questionnaire on 317 people working in 37 banks in six Asian countries. Research suggests that big data analytics strategies have an impact on internal processes and on the stability and financial performance of banks. Besides,it is indicated that banks are committed to proper data monitoring of their customers to complete operational efficiency and sustainability goals. Furthermore, our result proved that banks practicing Green Innovation strategies experience better environmental and economic performance because their employees are already trained in Green HR. Finally, from our study, it was found that internal and external green supply chain management practices have a positive effect on the environmental and financial performance of banks, thus ensuring that the bank of Association of Southeast Asian Nations(ASEAN) mitigates the environmental impact through its operations and ultimately experiences an increase in financial performance. 相似文献

We have reported that chymotrypsin B (CtrB) is not just a digestive enzyme but is also stored in lysosomes. Herein, we demonstrated a broad distribution of CtrB and explored the involvement of CtrB in apoptosis. Exposure of RH-35 cells to H2O2 or palmitate induced the redistribution of lysosomal CtrB into the cytoplasm as a result of lysosomal membrane permeabilization (LMP). Suppression of CtrB significantly blocked apoptosis, while overexpression of CtrB sensitized apoptosis markedly. CtrB could cleave Bid under neutral conditions. In RH-35 cells with Bid silenced, apoptosis induced by CtrB protein was attenuated, suggesting that CtrB mediates apoptosis of RH-35 cells mainly through processing Bid. Our data also suggest that LMP occurs earlier than mitochondrial outer membrane permeabilization; Bid activation initiated by caspase-8 might be reinforced by CtrB in consequence of LMP, which causes a positive feedback loop leading to the accumulation of tBid, and results in lysosome- and mitochondrion-dependent apoptosis. 相似文献

When they recognize a target cell, natural killer (NK) cells mount an attack to kill the target by exerting their cytotoxicity
via the exocytosis of cytotoxic granules. Although the details of this process (which includes the movement of cytotoxic granules
in the immune synapse and their fusion with the plasma membrane, releasing granzymes and perforin into the synaptic cleft)
are relatively better understood, the post-exocytosis regulation of the process is still largely unknown. Here we show that
a clathrin-dependent endocytosis stimulated by target cell occurs in NK92 cell line, which is closely correlated with granzyme
B recovery. Inhibition of the endocytosis significantly attenuates the cytotoxicity of NK92 cells. The NK cell recovery of
its released effector molecules, in turn, suggests that endocytosis may well play a key role in the post exocytosis regulation
of immune cells. 相似文献

过江隧道穿越既有铁路的相互影响是一个难点.依托重庆长江隧道穿越襄渝铁路工程进行研究,研究结果表明:过江隧道施工对既有铁路两个方向地表沉降的影响都很小,最大值为2.549 mm,故受影响的既有铁路附近地层不需做特殊加固处理,但要加强监控;既有铁路对过江隧道结构安全性及洞周位移影响也较小,在列车荷载作用下结构最小安全系数为6.8,过江隧道结构仍是偏于安全的,故隧道结构可不作加固处理,只需加强监控.研究成果为保证既有铁路的正常运营及过江隧道的结构安全性提供了理论基础,并可为相似工程提供参考. 相似文献

Plague is a pandemic human invasive disease caused by the bacterial agent Yersinia pestis. We here report a comparison of 17 whole genomes of Y. pestis isolates from global sources. We also screened a global collection of 286 Y. pestis isolates for 933 SNPs using Sequenom MassArray SNP typing. We conducted phylogenetic analyses on this sequence variation dataset, assigned isolates to populations based on maximum parsimony and, from these results, made inferences regarding historical transmission routes. Our phylogenetic analysis suggests that Y. pestis evolved in or near China and spread through multiple radiations to Europe, South America, Africa and Southeast Asia, leading to country-specific lineages that can be traced by lineage-specific SNPs. All 626 current isolates from the United States reflect one radiation, and 82 isolates from Madagascar represent a second radiation. Subsequent local microevolution of Y. pestis is marked by sequential, geographically specific SNPs. 相似文献
