In the age of stent deployment after balloon angioplasty. In stent restenosis (ISR) has become a major concern. Various coronary interventional measures and coronary artery bypass graft (CABG) has employed to manage the ISR. Although CABG seems to offer advantages over other coronary intervention methods in patients with multi vessel ISR; lack of appropriate graftable vessels often make the surgery difficult and end up with incomplete revascularization. Coronary endarterectomy with stent removal mitigated some of the limitations of CABG but initial results of this surgical measure were not favorable...

In-hospital outcomes of acute myocardial infarction (AMI) with cardiogenic shock (CS) were still not satisfactory even in the primary percutaneous coronary intervention (PCI) era. The aim of this study was to compare in-hospital outcomes of AMI with CS caused by right coronary artery (RCA) occlusion vs. left coronary artery (LCA) occlusion. Consecutive 894 AMI patients from January 2010 to March 2015 were screened for inclusion. A total of 114 AMI patients with CS were included as the final study population, and were divided into the RCA group (n = 56) and LCA group (n = 58)...

Here, we have developed a facile fluorometric system for the detection of adenosine triphosphate (ATP) by a rolling circle amplification (RCA) based on proximity ligation mediated amplification, and simultaneously achieved the release of the anticancer drug doxorubicin (DOX) through the mesoporous silicon system. Once the ATP molecule is present, the linker DNA will be released from the graphene oxide (GO) surface and hybridized to the template DNA of the GO surface joining with ligation enzyme. RCA reaction is followed by the addition of the phi29 DNA polymerase...

BACKGROUND: Movement of the stent delivery system in the coronary bed as a result of the cardiac cycle is a well-known clinical observation that usually is either underestimated or ignored. This effect may potentially jeopardize precise stent deployment. We used a novel technology to objectively measure the relative intracoronary device motion in the different coronary segments throughout the cardiac cycle. METHODS: A total of 193 patients undergoing coronary angiography were enrolled and their studies were analyzed for device movement using the SyncVision System (Philips Volcano)...

Developing a sensitive and selective sensing platform for the p53 gene and its mutation analysis is essential and may aid in early cancer screening and assessment of prognosis. Here, we developed a highly sensitive and selective p53 gene assay based on the coupling of a triple-helix magnetic probe (THMP) to a fluorescent liposome hybridization assembly, a process initiated by rolling circle amplification (RCA). In the presence of p53, the THMP unfolds and activates an enzymatic cleavage reaction, thus releasing the RCA primer and initiating the RCA product-assisted fluorescent liposome hybridization assembly...

Myocardial infarctions are frequently complicated by tachyarrhythmias, which commonly have wide QRS complexes (QRS duration > 120 milliseconds). Many published criteria exist to help differentiate between ventricular and supraventricular mechanisms. We present a case of a 61-year-old male with a history of hypertension, hyperlipidemia and coronary artery disease with prior stenting of the right coronary artery (RCA). He had been noncompliant with his antiplatelet medication and presented with cardiac arrest secondary to in-stent thrombosis...

BACKGROUND: Regional citrate anticoagulation (RCA) is being used increasingly in continuous renal replacement therapy (CRRT) as a safer alternative to heparin. However, complex metabolic control to avoid side effects have generated discrepancies about its introduction into everyday practice. We aimed to compare both anticoagulation techniques in terms of efficacy, safety and feasibility. METHODS: Observational retrospective study performed in 3 specialized ICUs in patients receiving CVVHDF with RCA between January 2013 and May 2016...

INTRODUCTION: Coronary arteries are exposed to several complex biomechanical forces during the cardiac cycle. These biomechanical forces potentially contribute to both native coronary artery disease, development of atherosclerosis and eventual stent failure. The aim of the present study was to characterize and define coronary artery axial rotation and the effect of stent implantation on this biomechanical factor. METHODS: Intravascular ultrasound (IVUS) images were obtained from porcine coronary arteries and analyzed in ultrasound analysis software used to evaluate myocardial strain and torsion in echocardiography...

Detection of pathogenic microorganisms is of great importance for public health and food safety. Traditional protocols can hardly meet the continuously increasing demand in sensitivity and specificity of pathogen detections. In this study, we adopted Vibrio parahaemolyticus (V. parahaemolyticus, Vp) as the model analyte, and developed an antibody-Vp-aptamer heterosandwich-based surface-enhanced Raman scattering (SERS) method in conjunction with in vitro isothermal amplification for sensitive detection of V...
