OBJECTIVE: Previous evidence suggested that intravascular ultrasound (IVUS) guidance could improve outcomes after drug-eluting stents (DES) placement, largely driven by data from observational studies. We, therefore, performed a meta-analysis and trial sequential analysis of randomized controlled trials to overcome this limitation. RESULTS: The retrieval process yielded 7 RCTs with 3,192 patients. Compared to the angiography guidance, IVUS-guided DES implantation was associated with a significant reduction in the major adverse cardiac events (MACE) (OR 0...

Gentiopicroside is a natural secoiridoid glycoside that may require metabolic activation to exert pharmacological effects. In this study, two active metabolites of gentiopicroside (M1 and M2) were isolated from rat urines and identified with our previous method. Most importantly, a fast, sensitive and selective ultra high-performance liquid chromatography-tandem mass spectrometry method was developed to simultaneously determine gentiopicroside and its two metabolites in rat plasma. The analytes and internal standard (swertiamarin) were separated on an ACQUITY UPLC(®) BEH C18 column (2...

Histidine-Proline-rich Glycoprotein (HPRG) is a plasma protein of vertebrates and several marine bivalves. Due to its multidomain structure consisting of several regions HPRG can interact with a variety of ligands, however the exact physiological role has not been discovered yet. Past purification approaches out of plasma or serum often led to co-purification of other proteins so that for a profound understanding of the function it is important to obtain a protein of high purity. Recent purification strategies were based upon metale chelate affinity chromatography followed by anion exchange chromatography or size exclusion chromatography, respectively...

Despite the progress in endovascular treatment of patients with peripheral arterial disease, restenosis remains the major drawback, especially in patients with femoropopliteal lesions. To reduce neointimal proliferation and subsequent restenosis the use of antiproliferative drug eluting devices was implemented in the endovascular treatment of femoropopliteal disease. Aiming to use the favorable effects of these antiproliferative agents and to reduce foreign body exposure in affected arteries, drug coated balloons (DCB) have been developed...

Due to the constant search for reliable methods to investigate glycoproteins in complex biological samples, an alternative approach combining affinity enrichment with rapid and sensitive analysis on-a-chip is presented. Glycoproteins were specifically captured by lectin-coated magnetic beads, eluted by competitive sugars, and investigated with microchip capillary gel electrophoresis (MCGE), i.e., CGE-on-a-chip. We compared our results to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) data, which turned out to be in very good agreement...

Development of coronary artery aneurysm (CAA) after implantation of drug-eluting stent is occasionally observed. We present a case of a 67-year-old man who underwent everolimus-eluting stent (EES) implantation in right coronary artery (RCA) for inferior wall myocardial infarction, and thereafter, giant CAAs were developed in the vessel of stent deployment, within 2 months. However, the patient was managed with coronary artery bypass grafting (CABG). On follow-up, the patient's condition was stable. To the best of our knowledge, we report the first case of occurrence of EES-associated giant CAAs in RCA subsequently treated with CABG...

Over the course of the 3 decades, percutaneous coronary intervention (PCI) with stent implantation transformed the practice of cardiology. PCI with stenting is currently the most widely performed procedure for the treatment of symptomatic coronary disease. In large trials, drug-eluting stents (DES) have led to a significant reduction in in-stent restenosis (ISR) rates, one of the major limitations of bare-metal stents. Due to these favorable findings, DES was rapidly and widely adopted enabling more complex coronary interventions...
