Transplantation of OECs to various neuronal injury locations showed a reparative impact; however, there was huge variability. By combining mRNA sequencing with bioinformatics analysis and immunohistochemistry, we characterized the cellular and molecular biological properties of OECs of the lamina propria and their response to neuronal injury. We found that OECs do not express NGFR (p75) under steady state conditions, questioning the common approach of isolating OECs with NGFR antibodies. While OECs express a peculiar combination of markers of different types of glial cells, they are strikingly similar to satellite glia cells of the dorsal root ganglion; for example, they showed marked upregulation of genes involved in lipid metabolism during neuronal regeneration. Similar to satellite glia cells and unlike Schwann cells, adult OECs did not proliferate in response to injury. Like endothelial cells at the blood-brain barrier and unlike other glia types, OECs showed extensive connections via the tight junction protein Claudin 5. Furthermore, OECs lack water channels, which probably explains why they sustain a stable environment after olfactory epithelium ablation. Regulation of the extracellular osmolarity seems to involve Aquaporin 1 in perineural fibroblasts together with high levels of KCNJ10, Na⁺K⁺ATPase, and gap junctions in OECs. Optimizing the clinical uses of these unique glia cells is probably made easier by this thorough characterization of marker gene expression in steady state and during neurogenesis.</p>","PeriodicalId":174,"journal":{"name":"Glia","volume":" ","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144793095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the rising incidence of cardiovascular complications in oncology patients, few large-scale studies have examined arrhythmia profiles across cancer subtypes and treatment trajectories in real-world emergency settings. As emergency physicians (EPs) managing acute cardio-oncologic complications, we commend this study and wish to highlight three findings with critical implications for emergency care, along with opportunities to strengthen clinical translation.&lt;/p&gt;&lt;p&gt;The significantly higher rate of emergency admissions among cancer patients with arrhythmias (58.9% vs. 57.6% in non-cancer patients; &lt;i&gt;p&lt;/i&gt; &lt; 0.05) underscores a growing challenge for emergency departments (EDs). This finding aligns with global trends showing increasing cardiovascular emergencies related to malignancy due to aging populations and the widespread use of cardiotoxic therapies [&lt;span&gt;2&lt;/span&gt;]. However, the underlying factors contributing to these admissions—whether related to arrhythmia severity, cancer progression, or gaps in outpatient care—remain insufficiently explored.

ED-specific algorithms would benefit from integrating oncology-informed variables such as current drug profiles, platelet counts, and malignancy characteristics to individualize AF management.&lt;/p&gt;&lt;p&gt;The observed frequencies of pneumonia (7.41%) and sepsis (2.26%) as clinical triggers for arrhythmia underscore the role of systemic inflammation in acute cardiac dysrhythmias.

However, conflicting reconstructions of the Cambrian redox landscape make it difficult to determine the extent of ocean oxygenation during this significant biotic event, particularly regarding the redox state of the global deep ocean. In this study, we present authigenic thallium isotope compositions (ε²⁰⁵Tl_auth) for two shale sequences from South China (Qingjiang and Weng'an) that span the Cambrian Stage 2–3 boundary to the appearance of the Qingjiang biota, approximately 521–518 million years ago (Ma), a timeframe that chronicles a particularly rapid interval of metazoan diversification and radiation in the broader Cambrian explosion. If this event occurred amid modern-like extents of global ocean oxygenation, we would expect a significant increase in the global extent of seafloor Mn-oxide burial to drive lower ε²⁰⁵Tl_auth values near the modern open-ocean composition of −6‱. Instead, we observe broadly stable ε²⁰⁵Tl_auth values of around −3 to −4‱ in both studied sections. The lack of any significant Tl isotope shifts in our dataset argues against a short-term global ocean oxygenation event and suggests the global deep ocean was not characterized by modern extents of oxygenation 521–518 Ma. We reinterpret contemporaneous near-modern Mo and U isotope compositions to signal a relatively minor increase in marine oxygenation, likely limited to the continental shelves. However, ε²⁰⁵Tl_auth lower than the average isotopic composition of approximately −2‱ in Ediacaran shales suggests a shift to comparatively better-oxygenated conditions sometime between ~555 Ma and 521 Ma. If diversification at this time was linked to increased ocean oxygen levels, these changes were likely more dominant in the relatively shallow-water settings of continental shelves most densely populated by Cambrian animals and were incapable of dramatically altering seawater Tl isotope mass balance through seafloor Mn-oxide burial.</p>\u0000 </div>","PeriodicalId":173,"journal":{"name":"Geobiology","volume":"23 4","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
