Fabrication of close-contact S-scheme CrBiO-BiO/FeO@porous carbon microspheres based on in-situ reaction: Enhanced photo-Fenton wastewater treatment.

Low photo-induced carrier recombination rate, exceptional light absorption, and advantageous recycling performance are crucial attributes of semiconductor photocatalyst for wastewater purification. Herein, based on in-situ reaction, close-contact S-scheme bismuth chromate/bismuth oxide/ferroferric oxide@porous carbon microspheres (CrBiO-BiO/FeO@PCs) (F-CBFP) was fabricated using alginates as precursor. Due to the abundance of functional groups on the porous carbon (PCs), BiO and CrBiO nanoparticles (NPs) are in situ deposited onto the highly conductive 3D magnetic porous FeO@PCs microsphere surface, which not only form tight interfacial contacts and reduces interfacial potential barriers but also prevent agglomeration or shedding of the NPs during photocatalytic reactions.

Protective effects of safranal on diabetic retinopathy in human microvascular endothelial cells and related pathways analyzed with transcriptome sequencing.

Aim: To determine the effect of safranal on diabetic retinopathy and its possible mechanisms.

Methods: We used human retinal microvascular endothelial cells (HRMECs) to test the influence of safranal . High glucose damage was established and an safranal was tested at various concentrations for its potential to reduce cell viability using the MTT assay.

Inhibitory effects of safranal on laser-induced choroidal neovascularization and human choroidal microvascular endothelial cells and related pathways analyzed with transcriptome sequencing.

Aim: To determine the effects of safranal on choroidal neovascularization (CNV) and oxidative stress damage of human choroidal microvascular endothelial cells (HCVECs) and its possible mechanisms.

Methods: Forty-five rats were used as a laser-induced CNV model for testing the efficacy and safety of safranal (0.5 mg/kg·d, intraperitoneally) on CNV.
