UCNPs@PVP-Hemin-GOx@CaCO Nanoplatform for Ferroptosis Self-Amplification Combined with Calcium Overload.

Due to the complexity of the tumor microenvironment (TME), current tumor treatments cannot achieve satisfactory results. A nanocomposite material, UCNPs@PVP-Hemin-GOx@CaCO (UPHGC NPs) is developed that responds to the TME and controls release to achieve multimodal synergistic therapy in tumor tissues. UPHGC NPs mediate photodynamic therapy (PDT), chemodynamic therapy (CDT), and starvation therapy (ST) synergistically, ultimately inducing self-amplification of ferroptosis.

Development of a social learning theory-based pressure injury training program for nursing assistants in Chinese nursing homes.

Introduction: Pressure injury (PI) is a significant concern in Chinese nursing homes, particularly in China, especially due to the rapidly aging population. Nursing assistants play a vital role in PI prevention and management but often lack adequate training. To address this gap, we developed a training program for nursing assistants based on Social Learning Theory (SLT), aimed at improving their competencies in PI prevention and management.

Biodegradable Vanadium-Based Nanomaterials for Photothermal-Enhanced Tumor Ferroptosis and Pyroptosis.

The designability and high reactivity of nanotechnology provide strategies for antitumor therapy by regulating the redox state in tumor cells. Here, we synthesize a kind of vanadium dioxide nanoparticle encapsulated in bovine serum albumin and containing disulfide bonds (VSB NPs) for photothermal-enhanced ferroptosis and pyroptosis effects. Mechanism studies show that disulfide bonds can effectively consume overexpressed glutathione (GSH) in the tumor microenvironment, leading to a decrease in glutathione peroxidase 4 (GPX4) activity.

Role of signaling lymphocytic activation molecule family of receptors in the pathogenesis of rheumatoid arthritis: insights and application.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation and joint damage. The signaling lymphocytic activation molecule (SLAMF) family of receptors are expressed on various hematopoietic and non-hematopoietic cells and can regulate both immune cell activation and cytokine production. Altered expression of certain SLAMF receptors contributes to aberrant immune responses in RA.

A comprehensive review of hook. f. in the treatment of rheumatic and autoimmune diseases: Bioactive compounds, mechanisms of action, and future directions.

Rheumatic and autoimmune diseases are a group of immune system-related disorders wherein the immune system mistakenly attacks and damages the body's tissues and organs. This excessive immune response leads to inflammation, tissue damage, and functional impairment. Therapeutic approaches typically involve medications that regulate immune responses, reduce inflammation, alleviate symptoms, and target specific damaged organs.
