Here, we conducted an individual-level time-stratified case-crossover study to explore the association of daily stock volatility (daily returns and intra-daily oscillations for three kinds of stock indices) with MACEs and suicide among more than 12 million individual decedents from all counties in the mainland of China between 2013 and 2019. For daily stock returns, both stock increases and decreases were associated with increased mortality risks of all MACEs and suicide. There were consistent and positive associations between intra-daily stock oscillations and mortality due to MACEs and suicide. The excess mortality risks occurred at the current day (lag 0 d), persisted for two days, and were greatest for suicide and hemorrhagic stroke. Taking the present-day Shanghai and Shenzhen 300 Index as an example, a 1% decrease in daily returns was associated with 0.74%–1.04% and 1.77% increases in mortality risks of MACEs and suicide, respectively; the corresponding risk increments were 0.57%–0.85% and 0.92% for a 1% increase in daily returns and 0.67%–0.77% and 1.09% for a 1% increase in intra-daily stock oscillations. The excess risks were more pronounced among individuals aged 65–74 years, males, and those with lower education levels. Our findings revealed considerable health risks linked to sociopsychological stressors, which are helpful for the government and general public to mitigate the immediate cardiovascular and mental health risks associated with stock market volatility.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"42 ","pages":"Pages 157-165"},"PeriodicalIF":10.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141282105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their activity has been utilized in artificial reactions, such as using the SAT WecE to transform valienone into the valuable α-glucosidase inhibitor valienamine. However, the low thermostability and limited activity on non-natural substrates have hindered their applications. Simultaneously improving stability and enzyme activity is particularly challenging owing to the acknowledged inherent trade-off between stability and activity. A customized combinatorial active-site saturation test–iterative saturation mutagenesis (CAST-ISM) strategy was used to simultaneously enhance the stability and activity of WecE toward valienone. Fourteen hotspots related to improving the stability–activity trade-off were identified based on evolutionary conservation and the average mutation folding energy assessment of 57 residues in the active site of WecE. Positive mutagenesis and combinatorial mutations of these specific residues were accomplished via site-directed saturation mutagenesis (SSM) and iterative evolution cycles. Compared with those of the wild-type (WT) WecE, the quadruple mutant M4 (Y321F/K209F/V318R/F319V) displayed a 641.49-fold increase in half-life (<em>t</em>_1/2) at 40 °C and a 31.37-fold increase in activity toward the non-natural substrate valienone. The triple mutant M3 (Y321F/K209F/V318R) demonstrated an 83.04-fold increase in (t_1/2) at 40 °C and a 37.77-fold increase in activity toward valienone. The underlying mechanism was dependent on the strengthened interface interactions and shortened transamination reaction catalytic distance, compared with those of the WT, which improved the stability and activity of the obtained mutants. Thus, we accomplished a general target-oriented strategy for obtaining stable and highly active SATs for artificial amino-sugar biosynthesis applications.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"42 ","pages":"Pages 185-195"},"PeriodicalIF":10.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142700862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we explored skin rejuvenation in aged mice through fecal microbiota transplantation (FMT) using feces from young mice. The results demonstrated enhanced water retention, thickened stratum corneum, increased collagen content, and improved epithelial cell differentiation in aged mice following FMT. Notably, FMT particularly increased the abundance of <em>Lactobacillus</em> and <em>Lactococcus</em> in aged mice, which were nearly undetectable in untreated aged mice. Non-targeted and targeted metabolomics analyses indicated that FMT significantly elevated levels of tryptophan (Trp) and its microbiota metabolites (e.g., indole-3-lactic acid (ILA)) in the feces and serum of aged mice. Both Trp and ILA appeared to rejuvenate aged skin by activating the aryl hydrocarbon receptor (AhR) to promote epidermal cell differentiation. In conclusion, FMT from young mice rejuvenated aged skin via Trp-metabolizing bacteria (<em>Lactobacillus</em> and <em>Lactococcus</em>) and Trp-derived metabolites, suggesting that interventions targeting Trp metabolites may effectively improve skin aging.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"42 ","pages":"Pages 26-38"},"PeriodicalIF":10.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142701431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the shale gas enrichment mechanism within the DART is not fully understood. This study reviews the formation of the Qiongzhusi shale gas reservoirs within the DART by comparing them with cotemporaneous deposits outside the DART, and several findings are presented. The gas production interval was correlated with the main phase of the Cambrian explosion (lower Cambrian stage 3). In the early Cambrian ecosystem, dominant animals likely accelerated the settling rates of organic matter (OM) in the upper 1st member of Є₁q (Є₁q1₂) by feeding on small planktonic organisms and producing larger organic fragments and fecal pellets. High primary productivity and euxinic conditions contributed to OM enrichment in the lower 1st member of Є₁q (Є₁q1₁). Additionally, shale reservoirs inside the DART demonstrated better properties than those outside in terms of thickness, brittle minerals, gas content, and porosity. In particular, the abundant OM pores inside the DART facilitated shale gas enrichment, whereas the higher thermal maturity of the shales outside the DART possibly led to the graphitization and collapse of some OM pores. Meanwhile, the overpressure of high-production wells inside the DART generally reflects better shale gas preservation, benefiting from the shale’s self-sealing nature, “upper capping and lower plugging” configuration, and limited faults and microfractures. Considering these insights, we introduced a “ternary enrichment” model for the Qiongzhusi shale gas. Although the current high gas production of Z201 was found at the reservoir 3, two additional reservoirs were identified with significant potential, thus suggesting a “multilayer stereoscopic development” strategy in future shale gas exploration within the DART.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"42 ","pages":"Pages 278-294"},"PeriodicalIF":10.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140755686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, misleading sensing information or malicious attacks in vehicular wireless networks can jeopardize CAVs’ perception and platoon safety. In this paper, we develop a two-dimensional robust control method for a mixed platoon, including a single leading CAV and multiple following HDVs that incorporate robust information sensing and platoon control. To effectively detect and locate unknown obstacles ahead of the leading CAV, we propose a cooperative vehicle–infrastructure sensing scheme and integrate it with an adaptive model predictive control scheme for the leading CAV. This sensing scheme fuses information from multiple nodes while suppressing malicious data from attackers to enhance robustness and attack resilience in a distributed and adaptive manner. Additionally, we propose a distributed car-following control scheme with robustness to guarantee the following HDVs, considering uncertain disturbances. We also provide theoretical proof of the string stability under this control framework. Finally, extensive simulations are conducted to validate our approach. The simulation results demonstrate that our method can effectively filter out misleading sensing information from malicious attackers, significantly reduce the mean-square deviation in obstacle sensing, and approach the theoretical error lower bound. Moreover, the proposed control method successfully achieves obstacle avoidance for the mixed platoon while ensuring stability and robustness in the face of external attacks and uncertain disturbances.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"42 ","pages":"Pages 244-266"},"PeriodicalIF":10.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142700955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study describes a phenotype-based screening strategy for screening NP libraries and discovering more effective compounds to mitigate or counteract the adverse consequences of ZEA exposure in animals. Using this strategy, we initially identified 96 NPs and evaluated the potency and efficacy of two effective candidate compounds, fraxetin, and hydroxytyrosol, based on embryonic phenotype and locomotor activity using a scoring system and the TCMacro method. Furthermore, we performed transcriptome and protein−protein interaction (PPI) network analyses to extract two mRNA signatures to query the Connectivity Map (CMap) database and predict NPs. The predicted NPs showed the potential to reverse the gene expression profiles associated with ZEA toxicity. Consequently, we further screened these compounds using our model, which indicated that hispidin, daphnetin, and riboflavin exhibit promising <em>in vivo</em> efficacy in zebrafish. Notably, throughout the process, fraxetin consistently stood out as the most promising NP. Biological pathway analysis and functional verification revealed that fraxetin completely reversed the toxic effects of ZEA at very low doses. This was achieved by repairing damaged cell apoptosis, modifying the cell cycle pathway, and preventing senescence induction, indicating good application potential. Overall, we demonstrated that this integration strategy can be successfully applied to effectively discover potential antidotes.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"42 ","pages":"Pages 196-212"},"PeriodicalIF":10.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141026176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
