BACKGROUND We assessed the hemodynamic performance of various prostheses and the clinical outcomes after aortic valve replacement, in different age groups. METHODS One-hundred-and-twenty patients with isolated aortic valve stenosis were included in this prospective randomized randomised trial and allocated in three age-groups to receive either pulmonary autograft (PA, n = 20) or mechanical pr...

OBJECTIVE Avoiding potentially irritating contact is a key point in vulvar lichen simplex chronicus (VLSC) management. This study aims to assess the use of nonirritating silk fabric underwear (Dermasilk) as an adjuvant tool in the treatment of VLSC. METHODS Twenty women with VLSC were enrolled in a 1-week open-label active treatment phase with topical 0.1% mometasone furoate (MMF) ointment. P...

How species diversity relates to productivity remains a major debate. To date, however, the underlying mechanisms that regulate the ecological processes involved are still poorly understood. Three major issues persist in early efforts at resolution. First, in the context that productivity drives species diversity, how the pathways operate is poorly-explained. Second, productivity per se varies ...

BACKGROUND In patient with acute myocardial infarction (AMI), the hyperintense area in T2-weighted imaging shows the periinfarct zone which was defined as the myocardial edema surrounding the irreversible myocardial injury (Fig 1A). Recent studies suggested that reduction of myocardial edema is a novel target to reduce irreversible injury and improve left ventricular remodeling. On the other ha...

BACKGROUND AND PURPOSE Increasing evidence suggests that iron deposition is present in the later stages of MS. In this study we examined abnormal phase values, indicative of increased iron content on SWI-filtered phase images of the SDGM in CIS patients and HC. We also examined the association of abnormal phase with conventional MR imaging outcomes at first clinical onset. MATERIALS AND METHO...

BACKGROUND Survival after prolonged ventricular fibrillation (VF) appears severely limited by 2 major factors: (1) low defibrillation success rates and (2) persistent post-countershock myocardial dysfunction. Biphasic (BP) waveforms may prove capable of favorably modifying these limitations. However, they have not been rigorously tested against monophasic (MP) waveforms in clinical models of ex...

BACKGROUND 6-Mercaptopurine (6-MP) and its prodrug azathioprine (AZA) have proven efficacy in the treatment of Crohn disease (CD). The immunosuppressive properties of AZA/6-MP are mediated by the intracellular metabolism of 6-MP into its active metabolites, 6-thioguanine nucleotides (6TGN) and 6methylmercaptopurine (6-MMP). Preliminary studies have suggested that the red blood cell concentratio...

OBJECTIVES The aim of this study was to determine long-term results between bioprosthetic (BP) and mechanical (MP) aortic valves in middle-aged patients. BACKGROUND It has not been established which is the best aortic valve substitute in patients ages 55 to 70 years. We conducted a randomized study to compare long-term outcomes between BP and MP aortic valves. METHODS Between January 1995 a...
