The chromatographic separation of MeOH extract from Clerodendron trichotomum Thunberg leaves led to the isolation of three phenylpropanoid compounds. Using spectroscopic methods, the structures of these compounds were determined as beta-(3', 4'-dihydroxyphenyl)ethyl-O-alpha-L-rhamnopyranosyl (1-->3)-beta-D-(4-O-caffeoyl)-glucopyranoside, acteoside(More)
We report the results of spectroscopic mapping observations carried out toward the Herbig-Haro objects HH7–11 and HH54 over the 5.2 − 37μm region using the Infrared Spectrograph of the Spitzer Space Telescope. These observations have led to the detection and mapping of the S(0) – S(7) pure rotational lines of molecular hydrogen, together with emissions in(More)
OBJECTIVE Human multidrug and toxin extrusion member 2 (MATE2-K, SLC47A2) plays an important role in the renal elimination of various clinical drugs including the antidiabetic drug metformin. The goal of this study was to characterize genetic variants of MATE2-K and determine their association with the pharmacokinetics of metformin. METHODS We screened(More)
Multidrug and toxin extrusion 1 (MATE1, SLC47A1), an organic cation transporter, plays an important role in the renal and biliary elimination of various clinical drugs, including the anti-diabetic drug metformin. The goal of this study was to identify and characterize novel genetic variants of MATE1. Five variants in the promoter region and two(More)
BACKGROUND/AIMS Home oxygen therapy (HOT) costs a great deal every year and demand for the service is growing. In Korea, health insurance has covered HOT since November 1, 2006. The objective of this study was to evaluate clinical features of patients who used long-term HOT due to chronic respiratory failure and to determine the appropriateness of oxygen(More)
AIM The aim of the present study was to evaluate the efficacy of a multidomain program in patients with Alzheimer's disease (AD). METHODS A total of 53 patients with probable AD participated in the present study. The participants were classified to a cognitive programming group (n = 32) and control group (n = 21). Participants in the cognitive(More)
We analyzed alcoholic extracts of herbs possessing anti-neosporal activity against Neospora (N.) caninum. To identify the chemical components of Sophora (S.) flavescens and Torilis (T.) japonica associated with anti-neosporal activity, specific fractions were isolated by high-performance liquid chromatography (HPLC). In vitro activity of the fractions(More)
We present our investigation of 319 Class II objects in Orion A observed by Spitzer/IRS. We also present the follow-up observations of 120 of these Class II objects in Orion A from the Infrared Telescope Facility/SpeX. We measure continuum spectral indices, equivalent widths, and integrated fluxes that pertain to disk structure and dust composition from IRS(More)
Class 0 protostars, the youngest type of young stellar objects, show many signs of rapid development from their initial, spheroidal configurations, and therefore are studied intensively for details of the formation of protoplanetary disks within protostellar envelopes. At millimetre wavelengths, kinematic signatures of collapse have been observed in several(More)
