Cucurbitacin IIb mitigates concanavalin A-induced acute liver injury by suppressing M1 macrophage polarization.

Cucurbitacins are a class of triterpenoid compounds extracted from plants and possess various pharmacological applications. Cucurbitacin IIb (CuIIb), extracted from the medicinal plant Hemsleya amabilis (Cucurbitaceae), has served as a traditional Chinese medicine for the treatment of bacterial dysentery and intestinal inflammation. CuIIb has been shown to exhibit anti-inflammatory activity; however, the protective effect of CuIIb against concanavalin A (Con A)-induced acute liver injury (ALI) and the fundamental mechanism remain unelucidated.

Recent advances in nanoarchitectonics of two-dimensional nanomaterials for dental biosensing and drug delivery.

Two-dimensional (2D) nanoarchitectonics involve the creation of functional material assemblies and structures at the nanoscopic level by combining and organizing nanoscale components through various strategies, such as chemical and physical reforming, atomic and molecular manipulation, and self-assembly. Significant advancements have been made in the field, with the goal of producing functional materials from these nanoscale components. 2D nanomaterials, in particular, have gained substantial attention due to their large surface areas which are ideal for numerous surface-active applications.

N6-methyladenosine modification of 3'tRF-AlaAGC impairs PD-1 blockade efficacy by promoting lactic acid accumulation in the tumor microenvironment of gastric carcinoma.

The balance between CD8 T cells and regulatory T (Treg) cells in the tumor microenvironment (TME) plays a crucial role in the immune checkpoint inhibition (ICI) therapy in gastric carcinoma (GC). However, related factors leading to the disturbance of TME and resistance to ICI therapy remain unknown. In this study, we applied N6-methyladenosine (m6A) small RNA Epitranscriptomic Microarray and screened out 3'tRF-AlaAGC based on its highest differential expression level and lowest inter-group variance.

Glutathione-Responsive Metal-Organic-Framework-Derived MnO/(A/R)TiO Nanoparticles for Enhanced Synergistic Sonodynamic/Chemodynamic/Immunotherapy.

Despite the potential of sonodynamic therapy (SDT) in treating malignant tumors, the lack of effective sonosensitizers has limited its clinical implementation. In this study, we explored the relationship between the heteroatom doping concentration in metal-organic frameworks and interface formation after pyrolysis by regulating the addition of manganese sources and successfully derived Z-scheme heterojunctions MnO/(A/R)TiO (MTO) in situ from MIL-125-NH (Ti/Mn). The electron transfer pathway introduced by interfacial contact promoted carrier separation and greatly preserved the effective redox components, significantly influencing the performance of reactive oxygen species generation.
