OBJECTIVE: Despite the popularity of coronary stenting in coronary artery disease (CAD), restenosis remains a challenging clinical problem. This study evaluated the efficacy of rosiglitazone for preventing in-stent restenosis in type 2 diabetic patients. RESEARCH DESIGN AND METHODS: We conducted a prospective, randomized, case-controlled trial involving 95 diabetic patients with CAD who were randomly assigned to either the control or rosiglitazone group (48 and 47 patients, respectively). Quanti

Abstract Hydrogels have been applied to improve stem cell therapy and drug delivery, but current hydrogel‐based delivery methods are inefficient in clinical settings due to difficulty in handling and treatment processes, and low off‐the‐shelf availability. To overcome these limitations, an adhesive hyaluronic acid (HA) hydrogel patch is developed that acts as a ready‐to‐use tissue tape for therapeutic application. The HA hydrogel patches functionalized with phenolic moieties (e.g., catechol, pyr

OBJECTIVE: To investigate whether sub-antimicrobial dose doxycycline (SDD) therapy for 120 d in chronic adult periodontitis patients had significant effects on gingival crevicular fluid (GCF) matrix metalloproteinase-8 (MMP-8) levels, and on gingival tissue MMP-9, tissue inhibitor of matrix metalloproteinases-1 (TIMP-1) and interleukin-6 (IL-6) levels. BACKGROUND: Tetracycline can significantly inhibit MMP activity in GCF and in gingival tissue, even in much lower dosage then a traditional antim

In the absence of repair mechanisms involving angiogenesis and cardiomyogenesis, loss of cardiomyocytes after myocardial injury is a primary causative factor in the progression toward heart failure. In an effort to reduce ischemic myocardial damage, we investigated the effects on infarcted myocardium of transplantation of genetically modified mesenchymal stem cells (MSCs) that specifically expressed vascular endothelial growth factor (VEGF) under hypoxic conditions. A hypoxia-inducible VEGF expr

Distant free flaps have become a routine option for reconstruction of large, complicated facial soft tissue defects. The challenge is to find a flap that is pliable to provide good contour and function. The purpose of this paper was to evaluate the use of superficial circumflex iliac artery perforator (SCIP) flaps for facial defects. From November 2010 to June 2013, facial reconstruction was performed on 6 patients (age range, 15-79 years). The harvesting technique was modified to elevate above

Serum aldosterone is significantly associated with central aortic PWV in hypertensive patients. The results demonstrate a possible role for aldosterone in developing central aortic stiffness and increased PWV in hypertensive patients.

BACKGROUND AND AIMS: Drug-coated balloons (DCBs) have demonstrated favourable outcomes following endovascular therapy for femoropopliteal artery (FPA) disease. However, uncertainty remains whether the use of intravascular ultrasound (IVUS) can improve the outcomes of DCBs. METHODS: This prospective, multicentre, randomized trial, conducted at seven centres in South Korea, compared the outcomes of IVUS-guided vs. angiography-guided angioplasty for treating FPA disease with DCBs. Patients were ass
