Resistance to HER2-targeted therapies presents a major challenge in the treatment of patients with HER2-positive breast cancer. N(6)-methyladenosine (m6A) modification plays a critical role in tumor progression; however, its role in mediating resistance to anti-HER2 therapy remains poorly defined. In trastuzumab-resistant HER2-positive breast cancer tissues, METTL14 expression is significantly upregulated and correlates with poor trastuzumab response.

Carbon monoxide (CO) is an important gas transporter and is closely related to a variety of physiological and pathological processes. Many fluorescent probes have been prepared for detecting CO, but most of them suffer from water-soluble fluorophores, which diffuse easily and are limited for application . Herein, a new solid-state fluorophore (HPQ-IM-OH) is prepared by introducing isophorone to HPQ, which has a long emission wavelength (680 nm) and good diffusion-resistance ability.

Leveraging inherent nonlinear dynamics, memristors have demonstrated superior performance in reservoir computing (RC). However, the use of different materials for reservoir nodes and readout layers poses significant challenges to integration. Moreover, the reported RC systems generally employ fixed reservoir nodes with limited temporal dynamics, which severely restricts the processing of sequences with complex temporal features in practical applications.

Cancer has become a serious threat to human health and the search for a safe and effective treatment method is particularly urgent. Chemodynamic therapy (CDT) is a non-invasive therapeutic method, but CDT still has certain disadvantages such as its limited therapeutic efficacy through overexpression of GSH and single treatment mode. In this paper, ZIF-based nanoparticles called Cu-SK-GOD@ZIF-90 are constructed for improved chemodynamic therapy and dual starvation therapy (ST).

The rational design and exploitation of cost-effective and robust catalysts for peroxymonosulfate (PMS) activation is of great significance. Herein, MnO/MnS nanoparticles encapsulated in Nitrogen-doped porous carbon skeleton (abbreviated as MnO/MnS@NPC) were first constructed through an easy two-step of impregnation along with subsequent pyrolysis technique and utilized to activate PMS for the elimination and mineralization of tetracycline (TC). Benefiting from the strong coupling of transition metal Mn with carbon-based material, the co-doping of heteroatom N and S, the enhanced electrical conductivity, and the hierarchical porous microarchitecture, the obtained MnO/MnS@NPC composite has been expected to present superior PMS activation capacity and pollutant elimination efficiency to its benchmark NPC and MnO@NPC, with 92.

Sustainable conversion of epoxides and propargylic amines using CO could produce valuable chemical products. Efficient conversion generally requires harsh conditions such as noble-metal catalysts, cocatalysts, and toxic solvents, thereby underscoring the crucial need for environmentally friendly non-noble-metal metal-organic framework (MOF) catalysts. In this study, we designed a novel zinc-based metal-organic framework (MOF) with a 5-fold interpenetrating diamond framework, specifically {[Zn(DMTDC)(bpy)]·HO} (), where HDMTDC represents 3,4-dimethylthieno[2,3-]thiophene-2,5-dicarboxylic acid and bpy denotes 4,4'-bipyridine.

The traditional methods for creating oxygen vacancies in materials present several challenges and limitations, such as high preparation temperatures, limited oxygen vacancy generation, and morphological destruction, which hinder the application of transition metal oxides in the field of zinc-air batteries (ZABs). In order to address these limitations, we have introduced a pioneering lithium reduction strategy for generating oxygen vacancies in δ-MnO@MXene composite materials. This strategy stands out for its simplicity of implementation, applicability at room temperature, and preservation of the material's structural integrity.
