Exploration of the effects of aortic cell subpopulations in AS remains challenging due to cellular heterogeneity. Phytosterol oxidation products (POPs) are key dietary factors influencing AS due to their potential pro-inflammatory effects in atherosclerotic mice. However, the contribution of alterations in cellular heterogeneity to this outcome and the exact mechanisms remain elusive. Here, we constructed a novel single-cell transcriptomic landscape of arteries in ApoE<sup>−/−</sup> mice fed an atherosclerotic diet without or with POPs. Combining single-cell RNA sequencing (scRNA-seq) with <em>in vitro</em> functional validation, we demonstrated that 7-ketositosterol, a major component of POPs, induced macrophages to skew the pro-inflammatory (M1) phenotype through the TLR4-IRF5 axis, thereby amplifying the inflammatory response. Notably, we verified the presence of this pro-inflammatory immune niche with the same molecular features using publicly available human arterial scRNA-seq data. This demonstrates that this is a reproducible characteristic in human AS. Our study shifts the current paradigm of exploring the biological effects of food components, and provides unprecedented perspectives for the application of single-cell technology to food nutrition research.","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"11 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144694234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By means of nanoskiving, ultrathin vertically aligned InSe ribbons were fabricated and subsequently transferred onto flexible polyethylene terephthalate (PET) substrates. The photoluminescence (PL) spectra revealed the tunability of the bandgap induced by strain, and the molecular dynamics (MD) simulations emphasized the influence of thickness on the mechanical properties. The vertically aligned InSe ribbons demonstrated an enhanced photoresponse under tensile strain in photodetectors, thereby demonstrating their potential for use in flexible optoelectronic devices.

In this study, we conducted a meta-analysis of microbial communities across nine datasets from bioreactors operated under varied conditions. Null model-based analysis indicated that stochastic processes predominantly govern community assembly during contaminant-free selection phases or stable operation. In contrast, deterministic processes consistently govern initial acclimation of activated sludge. These processes then shift toward stochastic dominance as the operation stabilizes. The presence of environmental disturbances—such as shock, refeeding, or stress—during operation increases the relative contribution of deterministic processes to community structuring. Notably, low bioreactor performance is associated with deterministic assembly, whereas sustained stable operation corresponds to stochastic dynamics, irrespective of reactor type or condition. These findings were integrated across four categories of biotreatment operations to illustrate how specific disturbances influence microbial community succession and performance stability. This work advances the theoretical understanding of microbial dynamics in engineered systems and offers practical insights into linking community assembly mechanisms with bioreactor function.","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"12 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional treatments, including drug administration and surgery, focus primarily on symptom relief but fail to address the underlying pathological mechanisms of IVDD. Extracellular matrix (ECM) degradation is closely related to the senescence of nucleus pulposus cells (NPCs) caused by highly levels of inflammation, overproduction of reactive oxygen species (ROS), DNA damage, low levels of autophagy, and the acidic microenvironment in the disc. This review explores the pathogenesis of IVDD mediated by NPC senescence, summarizes recent advances in biological therapy, and highlights the latest developments in antisenescent biomaterials. These biomaterials have the potential to delay disc degeneration by clearing senescent cells, inhibiting oxidative stress and inflammation, activating autophagy, and modulating the acidic microenvironment of the disc.

In the configuration designed by the Chinese partners, the air reactor (AR) is a transport bed, while the fuel reactor (FR) is a bubbling/turbulent fluidized bed. The solid circulation between the FR and AR is regulated by the overflow method, and the oxygen carrier (OC) from the AR cyclone returns to the FR riser.

During the operation, all solid fuel was fed into the dense bed of the FR, while only air was introduced into the AR. No electric or other external heating was applied, meaning that the whole pilot unit was heated by the oxidation of the OC within the AR. Hence, auto-thermal CLC operation was successfully achieved. Heating the unit was completed in 48 h; furthermore, switching to CLC mode was straightforward and took less than 1 h. During the operation, the temperature of the entire loop was stable. The temperatures of the AR and FR were 1000–1040 °C and 940–980 °C, respectively. Based on the operational data, the maximum CO<sub>2</sub> capture efficiency of the lignite-fed CLC unit was greater than 97%, and the minimum oxygen demand for unburnt gases from the FR was 2.45%.

Although protein glycosylation is one of the most common post-translational modifications, its evolutionary origin remains largely unexplored. Here, we performed a phylostratigraphic tracking of glycosylation machinery (GM) genes and their targets—glycosylated proteins—in a broad phylogenetic context. Our results show that the vast majority of human GM genes trace back to two evolutionary periods: the origin of all cellular organisms and the origin of all eukaryotes. This indicates that protein glycosylation is an ancient process likely common to all life, further elaborated in early eukaryotes. In contrast, human glycoproteins exhibited prominent enrichment signals in more recent evolutionary periods, suggesting an important role in the transition from metazoans to vertebrates. Focusing specifically on the N-glycosylation (NG) pathway, we noted that the majority of NG genes acting on the cytoplasmic side of the endoplasmic reticulum (ER) trace back to the origin of cellular organisms. This sharply contrasts with the rest of the NG pathway, which is oriented toward the ER lumen, where genes of eukaryotic origin predominate. In the Golgi, we also identified an analogous binary evolutionary origin of GM genes. We discuss these findings in the context of the evolutionary emergence of the eukaryotic endomembrane system and propose that the ER evolved through the invagination of a prokaryotic cell membrane containing an NG pathway.","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"3 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144630435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
