Enhancing photocatalytic partial oxidation of methane to methanol: Experimental investigation of 2D/metal oxide composite catalysts
منشور في 2025"…Among the three catalysts tested, the composite W₁₈O₄₉/g-C₃N₄ demonstrated remarkable catalytic activity of 62.3 μmol g−1 h−1 under visible light, nearly 4-fold higher than pristine W₁₈O₄₉ and 5-fold higher than g-C₃N₄. The enhanced performance is attributed to the forming of a Z-scheme heterojunction system, as evidenced by XPS analysis showing increased oxygen vacancy density and strong electronic coupling between the components, further confirmed by electrochemical characterization revealing improved charge separation efficiency. …"

Sensitivity of endoscopic ultrasound, multidetector computed tomography, and magnetic resonance cholangiopancreatography in the diagnosis of pancreas divisum
منشور في 2013"…Results: The sensitivity of EUS for pancreas divisum was 86.7%, significantly higher than the sensitivity reported in the medical records for MDCT (15.5%) or MRCP (60%) (P < 0.001 for each). On review by expert radiologists, the sensitivity of MDCT increased to 83.3% in cases where the pancreatic duct was visualized, with fair IOA ([kappa] = 0.34). …"

Resveratrol-Elicited PKC Inhibition Counteracts NOX-Mediated Endothelial to Mesenchymal Transition in Human Retinal Endothelial Cells Exposed to High Glucose
منشور في 2021"…Here, we investigate whether EndMT is implicated in the diabetic retinopathy fibrotic process and evaluate the possibility that resveratrol could counteract EndMT by inhibiting high glucose (HG)-induced increases in ROS. Primary Human Retinal Endothelial Cells (HRECs) were either pre-treated for 24 h with 1 µM resveratrol or left untreated, then glucose (30 mM) was applied at 3-day intervals for 10 days. qRT-PCR and ELISA were used to detect mRNA or protein expression of endothelial markers (CD31, CDH5, vWF) or mesenchymal markers (VIM, αSMA and collagen I), respectively. …"
