Article Abstract
Azoles are a class of antimicrobial drugs used clinically to treat yeast and fungal infections. Against pathogenic yeast and fungi, azoles act by inhibiting the activity of the cytochrome P450 Cyp51, which is involved in the synthesis of a critical component of the yeast and fungal cell membrane. Azoles have antibacterial activity, including against mycobacteria, but the basis for this activity is not well-understood. We demonstrated that imidazoles are bactericidal to . A marked increase in reactive oxygen species (ROS) was observed within imidazole-treated . The generation of ROS did not appear to be related to the mechanism of killing of imidazoles, as the addition of antioxidants or altered expression of detoxifying enzymes had no effect on growth. We examined the metabolic changes induced by econazole treatment in both wild-type and econazole-resistant mutant strains of . Econazole treatment induced changes in carbohydrates, amino acids, and energy metabolism in both strains. Notably, the untreated mutant strain had a metabolic profile similar to the wild-type drug-treated cells, suggesting that adaptation to similar stresses may play a role in econazole resistance.

Superoxide dismutases (SODs) are key regulators of reactive oxygen species (ROS) and redox balance. Although intracellular SODs have been extensively studied, growing attention has been directed toward understanding the roles of extracellular SODs in both Dictyostelium and mammalian systems. In Dictyostelium discoideum, SodC is a glycosylphosphatidylinositol (GPI)-anchored enzyme that modulates extracellular superoxide to regulate Ras, PI3K signaling, and cytoskeletal remodeling during directional cell migration.

Various cancer therapeutic strategies have been designed for targeting tumor-associated macrophages (TAMs), but TAM reprogramming-based monotherapy is often clinically hindered, likely due to the lack of a coordinated platform to initiate T cell-mediated immunity. Herein, we fabricated reactive oxygen species (ROS)-responsive human serum albumin (HSA)-based nanoparticles (PEG/IL12-IA NPs) consisting of indocyanine green (ICG), arginine (Arg), and interleukin 12 (IL12). Upon laser irradiation, the nanoparticles were found to be able to dissociate, thus facilitating the release of IL12.

This review delivers a focused and critical evaluation of recent progress in the green synthesis of carbon quantum dots (CQDs), with particular attention to state-of-the-art approaches utilizing renewable biomass as precursors. The main objective is to systematically examine innovative, environmentally friendly methods and clarify their direct influence on the core properties and photocatalytic performance of CQDs. The novelty of this review stems from its comprehensive comparison of green synthetic pathways, revealing how specific processes determine key structural, optical, and electronic attributes of the resulting CQDs.

The NOD‑like receptor family pyrin domain containing 3 (NLRP3) inflammasome is a key molecular complex that amplifies inflammatory cascades by maturing interleukin‑1 beta (IL-1β) and interleukin‑18 (IL-18) and inducing pyroptosis. It serves as a major driver and co-driver of numerous diseases associated with chronic inflammation. Dysregulated NLRP3 activation contributes to the progression of disorders such as rheumatoid arthritis, inflammatory bowel disease, neurodegenerative diseases and atherosclerosis.

Background: The protective function of the tetrandrine (TET)-mediated transient receptor potential vanilloid 2 (TRPV2) channel in myocardial ischemia/reperfusion injury (MI/RI) has been established in numerous investigations. The objective of the current study was to explain how TRPV2 further modulates downstream factors to influence the progression of MI/RI.
Methods: To this end, an MI/RI model in rats and a hypoxia-reoxygenation (H/R) cell model in H9c2 cells were constructed.
