Advanced glycation end products potentiate citrated plasma-evoked oxidative and inflammatory reactions in endothelial cells by up-regulating protease-activated receptor-1 expression
In this study, we investigated the effects of rivaroxaban, an inhibitor of factor Xa on 3% citrated human plasma-evoked reactive oxygen species (ROS) generation and RAGE, monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1) gene expression in AGE-exposed ECs. We further examined whether FR171113, an inhibitor of PAR-1 blocked the plasma-induced EC damage and if AGEs increased PAR-1 expression in ECs. Human citrated plasma stimulated ROS generation and RAGE, MCP-1 and ICAM-1 expression in ECs, all of which were potentiated by the treatment with AGEs. Rivaroxaban or FR171113 significantly inhibited these derangements in plasma- or plasma plus AGE-exposed ECs. Moreover, AGEs significantly increased the PAR-1 levels in ECs. The present study suggests that citrated plasma could induce oxidative and inflammatory reactions in ECs via the activation of thrombin-PAR-1 system and that AGEs could potentiate the plasma-evoked EC damages via up-regulation of PAR-1. Blockade of the crosstalk between AGE-RAGE axis and coagulation system by rivaroxaban might be a novel therapeutic target for thromboembolic disorders in diabetes.
Abstract Objectives: To investigate the influence of statins on major adverse cardiovascular events (MACE) in patients with coronary microvascular dysfunction (CMVD). Participants: 23,494 patients who received coronary angiography (CAG) were included. Thrombolysis in Myocardial Infarction, Myocardial Perfusion Grading (TMPG), a useful angiographic method, was used to evaluate CMVD. Results: Using multivariate analysis, NYHA III/IV (HR, 1.44; 95% CI, 1.03-2.01; P=0.031), PCI history (HR, 3.69; 95% CI, 2.57-5.31; P
Conclusion: Inner limiting membrane peeling during vitrectomy for macula-involving retinal detachment may substantially contribute to the visual recovery, reducing the incidence of secondary epiretinal membrane formation.
Conclusion: Swept-source OCTA is a reproducible technique in the assessment of macular perfusion in diabetic patients with special regards to foveal avascular zone analysis. The agreement with FFA is limited especially for diabetic macular ischemia grading. Fundus fluorescein angiography is more sensitive in identifying microaneurysms.
Conclusion: In Japanese patients with DME, IAI treatment was superior to laser for visual and anatomical outcomes and resulted in efficacy and safety outcomes similar to those in a non-Japanese patient population.
CONCLUSIONS The results indicated that longevity-associated FOXO3 variants were correlated with lower blood glucose levels in elderly women with type 2 diabetes in east China. PMID: 31009445 [PubMed - in process]
This study aims to assess the determinant of postprandial TG in healthy young adults.MethodsThis is a quasy-experimental study that involved 200 healthy young adults. This study compared fasting with postprandial TG and analyzed the relationship between postprandial TG with various demographic and metabolic parameters after ingestion of standardized high fat liquid meal.ResultThere was an upward trend from fasting TG to 2 h postprandial TG and 4 h postprandial TG. There was strong correlation between fasting TG and 2 h postprandial TG with 4 h postprandial TG (r = 0.731; p

We have recently read the report by Li et al. that inhibition of PTEN-induced putative kinase 1 (PINK1)/Parkin pathway activation is an effective treatment to improve myocardial ischemia/reperfusion (MI/R) injury . However, the specific mechanism by which PINK1 expression is regulated in MI/R injury has not yet been elucidated.
CONCLUSIONS: Pancreatic remnant volumetry and parenchymal thickness measurement after pancreaticoduodenectomy are correlated with exocrine insufficiency, but with limited predictive value. None of the preoperative measurements are withheld to predict postoperative exocrine function. Pre- and postoperative volumetry appear to have no use in predicting postoperative diabetes.
