Seagrasses provide numerous ecosystem services for coastal and estuarine environments, such as nursery functions, erosion protection, pollution filtration, and carbon sequestration. Zostera marina (common name "eelgrass") is one of the seagrass bed-forming species distributed widely in the northern hemisphere, including the Korean Peninsula. Recently, however, there has been a drastic decline in the population size of Z. marina worldwide, including Korea. We examined the current population genetic status of this species on the southern coast of Korea by estimating the levels of genetic diversity and genetic structure of 10 geographic populations using eight nuclear microsatellite markers...

Immunologic tolerance to solid organ and islet cell grafts has been achieved in various rodent models using antibodies directed at CD45RB and Tim-1. We have shown that this form of tolerance depends on regulatory B-cells. To elucidate further the mechanism by which Bregs induce tolerance we investigated the requirement of NK and NKT cells in this model. To do so, hyperglycemic B6, μMT, Beige or CD1d(-/-) mice received Balb/c islet grafts and treatment with the tolerance inducing regimen consisting of anti-CD45RB and anti -TIM1...

Transcatheter arterial chemoembolization (TACE)-induced complete pathological response (CPR) is known to improve post-resection outcomes of hepatocellular carcinoma (HCC). We aimed to assess the prognostic effects of CPR after preoperative TACE for HCC in patients who underwent hepatic resection (HR) or liver transplantation (LT). The clinical outcomes of patients showing CPR after HR (n=110) or LT (n=233) were analyzed. The control groups comprised patients with minimal recurrence risk as naïve single HCC ≤2 cm for HR (n=476), and one or two HCCs ≤2 cm for LT (n=184)...

INTRODUCTION: Tacrolimus is a calcineurin inhibitor used as an immunosuppressant drug in solid organ transplantation, and is mainly metabolized by cytochrome P450 (CYP) 3A4 and CYP3A5. Studies have shown an association between the CYP3A5 genotype and tacrolimus dose-adjusted trough concentrations. Variants in the genes PPARA, POR and CYP3A4 have recently been shown to influence tacrolimus metabolism. Furthermore, pharmacokinetic interaction between corticosteroid treatment and tacrolimus has been shown...

BACKGROUND: Grafts survive despite blood group antigens on the transplant being continuously exposed to antibodies in the blood of recipients in ABO-incompatible kidney transplantation (ABOi KT), owing to the mechanism of accommodation. We analyzed the immunodynamics of soluble ABH antigens in allografts from secretor donors and the influence of such immunodynamics on accommodation and subsequent graft survival in ABOi KT. METHODS: The genotype of a known human β-galactoside α-1,2-fucosyltransferase gene (FUT2), which determines soluble ABH antigen secretor status, was established in 32 donors for ABOi KT at the Severance Hospital, from June 2010 to July 2015...

BACKGROUND: Since the introduction of the Lung Allocation Score (LAS), the mean LAS has risen. Still, it remains uncertain whether mortality has improved in the most severely ill lung transplant recipients over this time period. METHODS: Using the United Network for Organ Sharing database, we identified 3,548 adult lung transplant recipients from May 4, 2005, to March 31, 2014, with a match-time LAS in the upper quartile (>75th%ile). We divided this population across three eras: 1 = May 4, 2005, to December 31, 2008 (n = 1,280); 2 = January 1, 2009, to December 31, 2011 (n = 1,266); and 3 = January 1, 2012, to March 31, 2014 (n = 1,002)...
