Tailoring Interfacial Active Sites and Valence States via Ligand Modulation in ZIF-Derived Catalysts for Enhanced Fenton-like Reactions.

Zeolitic imidazolate framework (ZIF)-derived catalysts have emerged as promising materials for Fenton-like advanced oxidation processes aimed at the degradation of persistent organic pollutants. However, the impact of the ligand chemistry on the interfacial properties and catalytic performance of these materials remains underexplored. Herein, Fe-doped ZIF precursors (ZIF-7/8/90) with different imidazolate ligands were pyrolyzed to obtain corresponding carbon-supported catalysts (ZIF-7/8/90-Fe-900) and evaluated under environmentally relevant water treatment conditions.

Endoplasmic reticulum-mitochondria coupling prompts ZBP1-mediated RPE cell PANoptosis in age-related macular degeneration.

Age-related macular degeneration (AMD) is the leading cause of central vision impairment among the elderly. Geographic atrophy is a defining characteristic of AMD, but the detailed mechanism for massive loss of retinal pigment epithelium (RPE) cells is not fully understood. In this study, we found that Z-DNA binding protein 1 (ZBP1), a sensor for dsDNA, is able to induce RPE cell PANoptosis.

Post-translational modifications in diabetic retinopathy: a comprehensive review of mechanisms, crosstalk and clinical prospects.

FXR suppress Müller cell activation by regulating cGAS/STING pathway in diabetic retinopathy.

Diabetic retinopathy (DR) is widely acknowledged as an ocular complication of diabetes mellitus involving retinal inflammation and secondary neuro/microvascular degeneration. Müller glial cells play a crucial role in regulating retinal homeostasis and neuroinflammation within the retina. Farnesoid X nuclear receptor (FXR) has emerged as a potential regulator of metabolic homeostasis and inflammatory responses as a bile acid nuclear receptor.

A study of specific immunoglobulin G4 expression in allergic rhinitis and its value in assessing efficacy and in predicting prognosis of sublingual immunotherapy.

Allergic rhinitis (AR) is a widespread health issue with a rising global prevalence, and sublingual immunotherapy (SLIT) has shown efficacy in AR treatment. We examined specific immunoglobulin G4 (sIgG4) expression in AR and its role in evaluating SLIT efficacy and predicting patient prognosis. We compared total nasal symptom score (TNSS), total medication score (TMS), visual analogue scale (VAS) score, inflammatory cytokines, and immune function markers in AR patients before and after SLIT.

FADS1 inhibition protects retinal pigment epithelium cells from ferroptosis in age related macular degeneration.

Purpose: Age-related macular degeneration (AMD) is the leading cause of vision loss among the elderly individuals. Retinal pigment epithelium (RPE) ferroptosis is a significant pathogenetic component in AMD. This study aims to elucidate the role and mechanisms of fatty acid desaturase 1 (FADS1) in ferroptosis as well as AMD progression.

Deciphering unique enzymatic pathways in sulfonamide biotransformation by direct ammonia oxidizer Alcaligenes ammonioxydans HO-1.

Heterotrophic nitrification, similar to autotrophic nitrification, involves key enzymes and reactive nitrogen intermediates during ammonia oxidation, which may influence antibiotic transformation. However, the interference between antibiotic transformation products from ammonia oxidation and secondary metabolites in heterotrophic nitrifiers makes antibiotic transformation pathways more complicated. In this work, we observe that the heterotrophic nitrifier Alcaligenes ammonioxydans HO-1 can effectively convert sulfonamide antibiotics.

An AIE probe for simultaneous monitoring of endogenous and exogenous hypochlorite and Zn at dual channels in living cells.

Zn and ClO may be associated with a variety of pathologies, and their simultaneous measurement is crucial for disease diagnosis and environmental protection. In this work, we synthesized an independent AIE probe, HNTE, through a one step reaction. The probe HNTE displayed a distinctive fluorescence color change from deep yellow to blue for ClO and to green for Zn.

YAP O-GlcNAcylation contributes to corneal epithelial cell ferroptosis under cigarette smoke exposure.

Cigarette smoke (CS) is an important indoor air pollutant associated with an increased risk of ocular surface disease. As the eye's outermost layer, the cornea is highly sensitive to air pollutants like CS. However, the specific mechanisms linking CS exposure to corneal dysfunction have not been fully elucidated.

Beautoide A, an Anti-Osteoclastogenic Sterol from Beauveria sp. NBUF147 Associated with an Irciniidae Sponge from the Marine Mesophotic Zone.

Mesophotic coral ecosystems (MCEs), located at depths ranging from 30-150 m, host some of the most diverse yet least explored marine bioresources, particularly significant for the discovery of new bioactive molecules. The fungus Beauveria sp. NBUF147, associated with an Irciniidae sponge from the mesophotic zone at a depth of 82 m, underwent chemical investigation that led to the identification of one new sterol, beautoide A (1), and one reported sterol, 3β,5α,9α-trihydroxy-(22E,24R)-ergosta-7,22-dien-6-one (2).

Association between indoor residual spraying and the malaria burden in Zambia and factors associated with IRS refusals: a case-control study in Vubwi District.
