A single 400 mg dose of moxifloxacin has been the standard positive control for thorough QT (TQT) studies. However, it is not clearly known whether a 400 mg dose is also applicable to TQT studies in Asian subjects, including Koreans. Thus, we aimed to develop a pharmacokinetic (PK)-pharmacodynamic (PD) model for moxifloxacin, to evaluate the time course of its effect on QT intervals in Koreans....

Objectives. Human placental extract (HPE) has begun to be used in Korea in various ways to improve health, even though evidence-based data is insufficient. This study investigated the effects of HPE on health status in elderly Koreans. Design. Randomized, single-blind, and case-control study design. Setting and Participants. Thirty-nine community-dwelling healthy Koreans ≥65 years of age. Inter...

Previous meta-analytic studies conducted in Western countries have consistently revealed impairments in theory of mind (ToM) in schizophrenia. However, there is no systematic meta-analytic review of ToM deficits in individuals with schizophrenia in non-Western countries. In addition, ToM impairments in individuals with schizophrenia have not been investigated in the distinctive domains (i.e., v...

BACKGROUND In this study, we used high-resolution DNA typing to investigate the distribution of HLA alleles and haplotypes in Koreans. METHODS HLA-A, -B, -C, and -DRB1 alleles were genotyped at the allelic (4-digit) level in 474 healthy Koreans. HLA genotyping was performed in two steps. Initially, serologic typing or generic-level DNA typing was performed using the PCR-sequence-specific olig...

INTRODUCTION There is ample evidence that certain habits, lifestyles and habitual or occasional behaviours have the potential of determining direct and/or indirect impact on health and on physical and mental wellbeing. For example, a healthy diet, regular and appropriate levels of physical activity, moderate alcohol consumption, and the abstinence from illegal drugs are considered healthy lifes...

The polymorphism in the factor XIII A-subunit gene (FXIII Val34Leu) has been recognized as a risk factor for primary intracerebral hemorrhage (PICH). In addition, FXIII Val34Leu has a significant ethnic heterogeneity. FXIII Val34Leu was detected in 41.7-54.8% of the Westerners, but in 2.5% of the Asians. We aimed to evaluate the prevalence of FXIII Val34Leu in patients with PICH and in healthy ...

The aim of this study was to determine the normal value of brachial-ankle pulse wave velocity (baPWV) and carotid-femoral pulse wave velocity (cfPWV) according to age group, gender, and the presence of cardiovascular risk factors in healthy Koreans, and to investigate the association between PWV and risk factors such as prehypertension, dyslipidemia, smoking, and obesity. We measured an arteria...
