BACKGROUND Ionotropic glutamate receptors of the N-methyl-D-aspartate receptor (NMDAR) type are expressed on keratinocytes and play a role in the proliferation, differentiation, and cornification of keratinocytes. However, the expression profile of NMDAR and its role in cutaneous malignancy is unclear. OBJECTIVE We analyzed the expression of NMDAR-1 in(More)
BACKGROUND/AIMS Pre-existing diabetes mellitus (DM) has been identified as an adverse prognostic variable associated with increased mortality in various cancers. Although DM and hyperglycemia are considered risk factors for pancreatic cancer (PC), antidiabetic treatments for patients with advanced PC have been overlooked. This study aimed to evaluate the(More)
BACKGROUND AND AIM The Model for End-Stage Liver Disease (MELD) has been widely used for predicting short-term mortality in patients with cirrhosis in the U.S. A modification of the MELD score was published in 2011. This was validated for Korean patients with cirrhosis. METHODS The medical records of patients with cirrhosis who were admitted to Konkuk(More)
BACKGROUND/AIMS The modification of the Model for End-Stage Liver Disease (MELD) scoring system (Refit MELD) and the modification of MELD-Na (Refit MELDNa), which optimized the MELD coefficients, were published in 2011. We aimed to validate the superiority of the Refit MELDNa over the Refit MELD for the prediction of 3-month mortality in Korean patients(More)
Let k be an imaginary quadratic field, h the complex upper half plane, and let τ ∈ h ∩ k, q = e πiτ. In this article, we obtain algebraic numbers from the 130 identities of Rogers-Ramanujan continued fractions investigated in [28] and [29] by using Berndt's idea ([3]). Using this, we get special transcendental numbers. For example, q 1/8 1 + −q 1+q + −q 2(More)
We first develop a criterion to determine normal bases (Theorem 2.4), and by making use of necessary lemmas which were refined from [3] we further prove that singular values of certain Siegel functions form normal bases of ray class fields over all imaginary quadratic fields other than Q(√ −1) and Q(√ −3) (Theorem 4.5 and Remark 4.6). This result would be(More)
BACKGROUND/AIMS A revised classification system for renal dysfunction in patients with cirrhosis was proposed by the Acute Dialysis Quality Initiative and the International Ascites Club Working Group in 2011. The aim of this study was to determine the prevalence of renal dysfunction according to the criteria in this proposal. METHODS The medical records(More)
