ObjectiveCell division cycle 42 (CDC42) regulates CD4+T-cell differentiation and participates in vascular stiffness and atherosclerosis and is involved in the progression of Stanford type B aortic dissection (TBAD). This study aimed to explore the correlation between serum CDC42 level and CD4+T cell subsets and in-hospital mortality in TBAD patients.MethodsSerum CDC42 and peripheral blood T-helper (Th) 1, Th2, and Th17 cells were detected in 127 TBAD patients by enzyme-linked immunosorbent assay and flow cytometry, respectively. Serum CDC42 was also quantified in 30 healthy controls.ResultsSerum CDC42 was decreased in TBAD patients vs. healthy controls (median [interquartile range (IQR)]: 418.0 (228.0–761.0) pg/ml vs. 992.0 (716.3–1,445.8) pg/ml, P ConclusionSerum CDC42 negatively associates with Th17 cells and is independently correlated with decreased in-hospital mortality risk in TBAD patients.</p

Low-Cost Synthesis of Hierarchical V₂O₅ Microspheres as High-Performance Cathode for Lithium-Ion Batteries

Hierarchical V₂O₅ microspheres composed of stacked platelets are fabricated through a facile, low-cost, and energy-saving approach. The preparation procedure involves a room-temperature precipitation of precursor microspheres in aqueous solution and subsequent calcination. Because of this unique structure, V₂O₅ microspheres manifest a high capacity (266 mA h g^–1), excellent rate capability (223 mA h g^–1 at a current density 2400 mA g^–1), and good cycling stability (200 mA h g^–1 after 100 cycles) as cathode materials for lithium-ion batteries
