Recent studies suggest that the intracoronary administration of bone marrow (BM)-derived mesenchymal stem cells (MSCs) may improve left ventricular function in patients with acute myocardial infarction (AMI). However, there is still argumentative for the safety and efficacy of MSCs in the AMI setting. We thus performed a randomized pilot study to investigate the safety and efficacy of MSCs in patients with AMI. Eighty patients with AMI after successful reperfusion therapy were randomly assigned

AIMS: This study aimed to evaluate the feasibility and safety of the left distal transradial approach (ldTRA) as a default route for coronary angiography (CAG) and percutaneous coronary intervention (PCI). METHODS AND RESULTS: Between October 2017 and January 2018, 200 consecutive patients were enrolled in a single centre. The left distal radial artery was punctured with a 20-gauge venipuncture catheter needle by three expert left radial approach operators. The success rates of arterial puncture

Purpose: In order to gain insight into the physicians’ awareness of and attitude towards management of overactive bladder (OAB) in males, we performed a nationwide survey of the current strategies that urologists use to diagnose and manage OAB in male patients. Materials and Methods: A probability sample was taken from the Korean Urological Association Registry of Physicians, and a random sample of 289 Korean urologists were mailed a structured questionnaire that explored how they manage benign

Purpose: Leuprorelin is a well known luteinizing hormone releasing hormone agonist. However, there are insufficient data on the efficacy and safety of high dose leuprorelin acetate, especially in Asian patients with prostate cancer. We aimed to investigate the safety and efficacy of leuprorelin acetate 22.5 mg administered at three-month intervals in patients with prostate cancer. Materials and Methods: In an open, prospective clinical trial enrolling 47 patients, we aimed to assess the efficacy

전환사채란 어느 일정한 기간을 경과하면 미리 예정된 가액으로 사채를 주식 으로 전환할 수 있는 사채를 말한다. 전환사채와 관련하여 전환사채 투자자는 주가가 상승하지 않으면 사채를 상환기간까지 보유하여 이자분의 이익을 얻고 반대로 주가가 상승하면 주식으로 전환하여 매각이익을 얻을 수 있다. 반면에 전환사채 발행회사는 일반사채보다 낮은 이율로 전환사채를 발행함으로써 저렴 한 비용으로 자본을 조달하고 추후에는 사채를 주식으로 전환하여 줌으로써 채 무를 자기자본화할 수 있는 장점이 있는 자금조달방식이다. 전환사채의 발행시 이사회에서 결정하여야 하는 전환조건은 협의의 전환조건 을 의미하며 이는 전환가액의 결정을 의미한다. 전환가액은 그 전환가액의 산 정방식에 따라 액면등가전환방식이나 시가전환방식에 의하여 이루어지 있다. 액면등가방식이란 발행회사의 주식의 액면을 기준으로 삼아 주식의 전환가액을 산정하는 방식인데 반하여 시가전환방식은 전환사채 발행 당시의 주가를 기준 으로 전환가액을 산정하는 방

Traditionally, corporate finance has consisted of equity finance and debt finance. However the recent trend called ‘Mezzanine Finance’ combines the elements of both debt and equity and is consisted of mezzanine loan and hybrid security. Mezzanine loan has been clearly categorized as debt, but hybrid security has characterizations of both equity and debt. Hybrid securities were frist introduced to Korean financial system during the 1998 Financial Crisis when the Basel Committee of the Bank of Int
