To explore the antioxidant activity of enzymatic hydrolysates of from Dalian and preliminarily elucidate their mechanisms of action both and . Samples were hydrolysed using alcalase, protamex, and neutrase. 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging assays showed that the alcalase hydrolysate had the highest antioxidant activity, with IC values of 4.

Institute of Ophthalmology, School of Medicine, Jinan University, Guangzhou, China.
Purpose: To investigate the therapeutic efficacy of BEZ235, a dual PI3K/mTOR inhibitor, in suppressing pathological neovascularization in an oxygen-induced retinopathy (OIR) mouse model and explore the role of cyclin D1 in endothelial cell cycle regulation.
Methods: Single-cell RNA sequencing was performed to analyze gene expression and cell-cycle alterations in retinal endothelial cells under normoxic and OIR conditions. The effects of BEZ235 on human umbilical vein endothelial cells (HUVECs) and human retinal microvascular endothelial cells (HRMECs) were evaluated by assessing cell viability, cell-cycle progression, proliferation, migration, and tube formation.

About one-fifth of people in industrialised countries are tattooed, potentially putting them at risk of exposure to possible carcinogenic or otherwise harmful substances. This study aims to determine the exposure to soluble tattoo ink ingredients and their excretion within 24 h after tattooing. In this clinical study, 24 subjects were tattooed with black or red tattoo ink to which the 3 tracer substances, potassium iodide, 4-aminobenzoic acid (PABA) and 2-phenoxyethanol (PEtOH), had been added to mimic known substances found in tattoo inks.

Purpose: Following the initial reports demonstrating the feasibility of immunoPET imaging of simian immunodeficiency virus (SIV) using gp120-targeting monoclonal antibodies in non-human primates, replication efforts of the imaging system in human immunodeficiency virus (HIV)-infected individuals have yielded conflicting results. Herein, we used two anti-gp120 antibodies, 7D3 and ITS103.01LS-F(ab'), to interrogate the reproducibility of gp120-targeting probes for immunoPET imaging of SIV in rhesus macaques.
