Electron transfer is a fundamental process in host–guest interactions, significantly influencing nanoscale physicochemical processes. Elucidating the mechanism by which the host influences the electronic structure of the guest is essential for elucidating these interactions. This study reports the successful synthesis of a material system consisting of precisely resolved AgBr nanowires encapsulated within single-walled carbon nanotubes (SWCNTs) that has been successfully synthesized and utilized to investigate the intrinsic electron transfer across 1D vdWHs. Cyclic voltammetry (CV) was employed to investigate the 1D vdWH interaction between AgBr and SWCNTs, which provided a more intuitive and accurate characterization of the charge transfer from SWCNTs to AgBr. Furthermore, Kelvin probe force microscopy showed a 149 mV reduction in the average surface potential of carbon nanotubes after AgBr filling, supporting the efficacy of CV in probing electron dynamics in 1D vdWHs. Finally, theoretical calculations indicated a charge transfer of 0.11 e^– per simulation cell, reinforcing the effectiveness of CV in assessing the interactions within 1D vdWHs.","PeriodicalId":15,"journal":{"name":"ACS Earth and Space Chemistry","volume":"72 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142609855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, in order to reduce the emitter sensitivity to charge noise, inversion symmetric systems are typically designed, providing a stable emission frequency with a quadratic-only dependence on the applied field. However, such nonlinear behavior might be reflected in correlations between the tuning ability and unwanted spectral fluctuations. Here, we provide experimental evidence of this trend using molecular quantum emitters in the solid state cooled down to liquid helium temperatures. We finally combine the electric field generated by electrodes, which is parallel to the molecule’s induced dipole, with optically excite long-lived charge states acting in the perpendicular direction. Based on the anisotropy of the molecule’s polarizability, our two-dimensional control of the local electric field allows us not only to tune the emitter’s frequency but also to sensibly suppress the spectral instabilities associated with field fluctuations.","PeriodicalId":15,"journal":{"name":"ACS Earth and Space Chemistry","volume":"11 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142609856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the presence of infection- and vaccine-induced immunity, SARS-CoV-2 infections remain a major global health concern because of the emergence of SARS-CoV-2 variants that can cause severe acute coronavirus disease 2019 (COVID-19) or enhance Long Covid disease phenotypes. About 5 to 10% of SARS-CoV-2–infected individuals develop Long Covid, which, similar to acute COVID 19, often affects the lung. However, Long Covid can also affect other peripheral organs, especially the brain. The causal relationships between acute disease phenotypes, long-term symptoms, and involvement of multiple organ systems remain elusive, and animal model systems mimicking both acute and post-acute phases are imperative. Here, we review the current state of Long Covid animal models, including current and possible future applications.","PeriodicalId":15,"journal":{"name":"ACS Earth and Space Chemistry","volume":"2 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commonly reported symptoms include fatigue, weakness, postexertional malaise, and cognitive dysfunction, with many other symptoms reported. Symptom range, duration, and severity are highly variable and partially overlap with symptoms of myalgic encephalomyelitis/chronic fatigue syndrome and other post-acute infectious syndromes, highlighting opportunities to define shared mechanisms of pathogenesis. Potential mechanisms of Long Covid are diverse, including persistence of viral reservoirs, dysregulated immune responses, direct viral damage of tissues targeted by SARS-CoV-2, inflammation driven by reactivation of latent viral infections, vascular endothelium activation or dysfunction, and subsequent thromboinflammation, autoimmunity, metabolic derangements, microglial activation, and microbiota dysbiosis. The heterogeneity of symptoms and baseline characteristics of people with Long Covid, as well as the varying states of immunity and therapies given at the time of acute infection, have made etiologies of Long Covid difficult to determine. Here, we examine progress on preclinical models for Long Covid and review progress being made in clinical trials, highlighting the need for large human studies and further development of models to better understand Long Covid. Such studies will inform clinical trials that will define treatments to benefit those living with this condition.","PeriodicalId":15,"journal":{"name":"ACS Earth and Space Chemistry","volume":"35 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Travel to High-Volume Centers and Survival After Esophagectomy for Cancer","authors":"Sara Sakowitz, Syed Shahyan Bakhtiyar, Saad Mallick, Jane Yanagawa, Peyman Benharash","doi":"10.1001/jamasurg.2024.5009","DOIUrl":"https://doi.org/10.1001/jamasurg.2024.5009","url":null,"abstract":"ImportanceOngoing efforts have encouraged the regionalization of esophageal adenocarcinoma treatment to high-volume centers (HVCs). Yet such centralization has been linked with increased patient travel burden and reduced postoperative continuity of care.ObjectiveTo determine whether traveling to undergo esophagectomy at HVCs is linked with superior overall survival compared with receiving care locally at low-volume centers (LVC).Design, Setting, and ParticipantsThis cohort study considered data for all patients diagnosed with stage I through III esophageal adenocarcinoma in the 2010-2021 National Cancer Database. Patients were stratified based on distance traveled to receive care and the annual esophagectomy volume at the treating hospital: the travel-HVC cohort included patients in the top 25th percentile of travel burden who received care at centers in the top volume quartile, and the local-LVC cohort represented those in the bottom 25th percentile of travel burden who were treated at centers in the lowest volume quartile. Data were analyzed from July 2023 to January 2024.Main Outcomes and MeasuresThe primary end points were overall survival at 1 year and 5 years. Secondary end points included perioperative outcomes and factors linked with traveling to receive care.ResultsOf 17 970 patients, 2342 (13%) comprised the travel-HVC cohort, and 1969 (11%), the local-LVC cohort. The median (IQR) age was 65 (58-71) years; 3748 (87%) were male and 563 (13%) were female. After risk adjustment and with care at local LVCs as the reference, traveling to HVC was associated with superior survival at 1 year (hazard ratio for mortality [HR], 0.69; 95% CI, 0.58-0.83) and 5 years (HR, 0.80; 95% CI, 0.70-0.90). Stratifying by stage, traveling to HVCs was associated with comparable outcomes for stage I disease but reduced mortality for stage III (1-year HR, 0.72; 95% CI, 0.60-0.87; 5-year HR, 0.83; 95% CI, 0.74-0.93). Further, traveling to HVC was associated with greater lymph node harvest (β, 5.08 nodes; 95% CI, 3.78-6.37) and likelihood of margin-negative resection (adjusted odds ratio, 1.83; 95% CI, 1.29-2.60).Conclusions and RelevanceTraveling to HVCs for esophagectomy was associated with improved 1-year and 5-year survival compared with receiving care locally at LVCs, particularly among patients with locoregionally advanced disease. Future studies are needed to ascertain barriers to care and develop novel targeted pathways to ensure equitable access to high-volume facilities and high-quality oncologic care.","PeriodicalId":15,"journal":{"name":"ACS Earth and Space Chemistry","volume":"80 1","pages":""},"PeriodicalIF":16.9,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
