Major concerns about donor safety cause controversy and limit the use of living donor liver transplantation to overcome organ shortages. The Korean Organ Transplantation Registry established a nationwide organ transplantation registration system in 2014. We reviewed the prospectively collected data of all 832 live liver donors who underwent procedures between April 2014 and December 2015. We allocated the donors to a left lobe group (n=59) and a right lobe group (n=773) and analyzed the relations between graft types and remaining liver volumes and complications (graded using the Clavien five-tier grading system)...

Perilla (Perilla frutescens) is an economically and culturally important plant in East Asia. Plant breeding between cultivars has enhanced the genetic diversity of perilla overall, but means that functionally diverse subspecies are more difficult to identify and distinguish. In this study, we developed gene-based DNA markers to distinguish between the Korean herbal medicinal perilla varieties. We identified informative simple sequence repeat (SSR) regions on the promoter regions of the Myb-P1 and dihydroflavonol 4-reductase (DFR) genes, as well as a large insertion-deletion (indel) region in the limonene synthase (LS) gene, and developed markers to characterize the distinct subspecies differences (PfMyb-P1pro, PfDFRpro, and PfLS, respectively)...

Obesity is closely associated with metabolic diseases including type 2 diabetes. One hallmark characteristics of obesity is chronic inflammation that is coordinately controlled by complex signaling networks in adipose tissues. Compelling evidence indicates that reactive oxygen species (ROS) and its related signaling pathways play crucial roles in the progression of chronic inflammation in obesity. The pentose phosphate pathway (PPP) is an anabolic pathway that utilizes the glucoses to generate molecular building blocks and reducing equivalents in the form of NADPH...

BACKGROUND: Endoscopic resection (ER) is a widely accepted treatment for patients with early gastric cancer (EGC) with no lymph node metastasis. Occasionally, however, additional surgery is needed due to an incomplete resection. The purpose of this study was to detect clinical factors which might identify patients at greater risk of additional surgery after ER and to suggest an alternative treatment strategy for these patients. METHODS: This study retrospectively analyzed 350 patients with gastric cancer who underwent radical gastrectomy and lymphadenectomy after ER in a single institution between July 2004 and July 2014...

We investigated changes in the crystal structure of GeTe during its phase transition. Using density functional theory (DFT) calculations, four possible crystal structures were identified: R3m, P1, Cm, and Fm3m. Among these, P1 and Cm were examined here for the first time. By calculating the internal energy of the crystal volume change, we verified that P1, R3m, and Cm can coexist in crystalline GeTe. The X-ray diffraction spectra of annealed and laser-irradiated GeTe films revealed coexisting P1 or R3m and Cm...

Axl is an oncogenic receptor tyrosine kinase that plays a role in many cancers. LIGHT (Lymphotoxin-related inducible ligand that competes for glycoprotein D binding to herpesvirus entry mediator on T cells) is a ligand that induces robust anti-tumor immunity by enhancing the recruitment and activation of effector immune cells at tumor sites. We observed that mouse EL4 and human Jurkat T lymphoma cells that stably overexpressed Axl also showed high expression of LIGHT. When Jurkat-Axl cells were treated with Gas6, a ligand for Axl, LIGHT expression was upregulated through activation of the PI3K/AKT signaling pathway and transcriptional induction by Sp1...

Functional dyspepsia (FD) is a constellation of epigastric symptoms originating in the gastroduodenal region without organic and metabolic cause. However, similar confounding symptoms can also appear in patients with gallbladder (GB) dyskinesia. Therefore, symptoms of GB dyskinesia may be mistaken for FD. We aimed to identify GB dyskinesia as a cause of FD symptoms compatible with the Rome IV criteria and the need for an evaluation of GB function in patients with FD symptoms.We investigated information of patients with FD symptoms who underwent a quantitative Tc-diisoproyl iminodiacetic acid cholescintigraphy (DISIDA scan) through electronic medical records, and GB dyskinesia was judged to be the cause of the FD symptoms if the symptoms disappeared as GB function normalized on the follow-up DISIA scan in patient with decreased GB function on the initial DISIDA scan...
