Microinvasive intrascleral double continuous suture repair surgery for cyclodialysis clefts.

Background: The traditional suturing method for cyclodialysis cleft usually requires an incision in the sclera for direct suturing, resulting in greater damage and a high risk of postoperative complications. The purpose of this work is to propose a newly intrascleral double continuous suture repair technique for the treatment of cyclodialysis clefts.

Methods: Seven patients with cyclodialysis cleft underwent microinvasive intrascleral double continuous suture repair surgery to restore the attachment of the detached ciliary body to the sclera without scleral incision.

Tollip suppresses MyD88-mediated NF-κB activation by enhancing MyD88 ubiquitination levels in large yellow croaker (Larimichthys crocea).

Toll-interacting protein (Tollip) plays an important role in the innate immune response by negative regulation of the TLR-IL-1R signaling pathway. MyD88 serves as a universal adaptor in TLR-mediated NF-κB activation. However, the regulation mechanisms of Tollip in piscine MyD88-mediated NF-κB activation is largely unknown.

Role of red blood cell distribution in predicting drug-eluting stent restenosis in patients with stable angina pectoris after coronary stenting.

Background: It has been reported that increased red blood cell distribution width (RDW) predicts adverse events in cardiovascular disease and in patients undergoing percutaneous coronary intervention.

We aimed to investigate the relationship between serum RDW levels and in-stent restenosis (ISR) after coronary stenting with DES in stable angina pectoris (SAP) patients.

One-year clinical outcomes of everolimus- versus sirolimus-eluting stents in patients with acute myocardial infarction.

Background: In contrast to many studies comparing everolimus-eluting stent (EES) with paclitaxel-eluting stent (PES), data directly comparing EES with sirolimus-eluting stent (SES) are limited, especially in patients with acute myocardial infarction (AMI).

Methods: This study includes 2911 AMI patients treated with SES (n=1264) or EES (n=1701) in Korea Acute Myocardial Infarction Registry (KAMIR). Propensity score matching was applied to adjust for baseline imbalance in clinical and angiographic characteristics, yielding a total of 2400 well-matched patients (1200 receiving SES and 1200 receiving EES).

Materials And Methods: A total of 1729 consecutive patients without significant CVD who underwent coronary angiography and intracoronary ACh test between November 2004 and August 2010 were analyzed.

Six-month angiographic and one-year clinical outcomes of polymer free paclitaxel-eluting stent in patients with ST-segment elevation myocardial infarction: a comparison with permanent polymer sirolimus-eluting stent.

Background: Since permanent polymer is implicated in adverse events associated with delayed vessel healing after drug eluting stents (DES) implantation, great efforts have been made to develop more biocompatible DES with biodegradable polymer or without polymer. The present study aimed to evaluate the safety and efficacy of polymer free paclitaxel-eluting stents (PF-PES) in comparison with permanent polymer sirolimus-eluting stents (PP-SES) in patients with acute ST-segment elevation myocardial infarction (STEMI).

Methods: Patients with STEMI were randomly assigned to receive PP-SES (n = 55), and PF-PES (n = 50).

Unrestricted use of 2 new-generation drug-eluting stents in patients with acute myocardial infarction: a propensity score-matched analysis.

Objectives: This study sought to compare everolimus-eluting stents (EES) with zotarolimus-eluting stents (ZES) in patients with acute myocardial infarction (AMI).

Background: There is a paucity of data to exclusively evaluate the safety and efficacy of second-generation drug-eluting stents (DES) in the setting of AMI.

Methods: The present study enrolled 3,309 AMI patients treated with ZES (n = 1,608) or EES (n = 1,701) in a large-scale, prospective, multicenter registry-KAMIR (Korea Acute Myocardial Infarction Registry).

Materials And Methods: Twenty-one rabbits were randomized to receive overlapping stents in the iliac artery for 3 months {distal sirolimus-eluting stent (SES, Cypher™)+proximal paclitaxel-eluting stent (PES, Taxus™) (C+T, n=7), distal Taxus+proximal Cypher (T+C, n=7) and bare metal stent (BMS)+BMS (B+B, n=7)}. Endothelial function was evaluated by the acetylcholine provocation test during follow-up angiography.

Impact of low-dose aspirin on coronary artery spasm as assessed by intracoronary acetylcholine provocation test in Korean patients.

High-dose aspirin has been reported to aggravate coronary artery spasm (CAS). However, it is unknown whether low-dose aspirin (LDA; 100 mg) has deleterious impact on CAS. We assessed the impact of LDA on CAS induced by intracoronary acetylcholine (ACh) provocation test.

'Smoker's paradox' in young patients with acute myocardial infarction.

1. Of the patients suffering from acute myocardial infarction (AMI), smokers are younger than non-smokers, which may be a major confounding factor causing 'smoker's paradox'. Therefore, in the present study we evaluated the 'smoker's paradox' in young patients with AMI.
