The rapid immunocapture assays, OptiMal and ICT, were evaluated from 87 individuals for the diagnosis of malaria infections directly from whole blood. A total of 87 individuals was examined for malaria parasites by microscopic examination of Giemsa-stained blood smears, and 65 cases were positive for Plasmodium vivax by microscopy. Correspondingly, the(More)
BACKGROUND The information on the incidence, seasonal variation and clinical pattern of respiratory virus infections is very important for clinicians in managing their patients. This study was aimed to define the epidemiology of respiratory viral pathogens in Seoul and the neighboring areas from March 2004 to February 2006. METHODS A total of 6,533(More)
Protein chips are a powerful emerging technology with extensive biomedical applications. However, the development of optimal, economical surface materials capable of maintaining the activity of embedded proteins is a challenge. Here, we introduce a new optimized, low-cost, sol-gel biomaterial for use in protein chips with femtogram-level sensitivity. A(More)
BACKGROUND The Korean Laboratory Accreditation Program (KLAP) by the Korean Society of Laboratory Medicine (KSLM) was started in 1999. We summarized history and achievement of KLAP for the last 8 yr. METHODS We analyzed 8 yr data (1999-2006) of historical events, trends of participating laboratories, and scores according to the impact of the question to(More)
This study evaluated the performance of a handheld coagulation analyzer for measurements of capillary blood specimens of 93 outpatient cardiology patients with atrial fibrillation who were receiving oral anti-coagulant therapy. The international normalized ratio (INR) results of the CoaguChek XS system (Roche Diagnostics) were compared with those obtained(More)
The species identification within Mycobacterium terrae complex has been known to be very difficult. In this study, the genomic diversity of M. terrae complex with eighteen clinical isolates, which were initially identified as M. terrae complex by phenotypic method, was investigated, including that of three type strains (M. terrae, M. nonchromogenicum, and(More)
BACKGROUND Plasma adiponectin is decreased in patients with coronary artery diseases, especially in patients with acute coronary syndrome (ACS). However, the correlation between plasma adiponectin and variant angina pectoris (VAP) has not been verified. Plasma adiponectin concentrations between VAP and other coronary artery diseases was compared in the(More)
The mechanisms of resistance to macrolides in 51 erythromycin-resistant clinical isolates of Streptococcus pyogenes collected from 1997 through 2003 in Seoul, Korea were evaluated. They were characterized by their antimicrobial susceptibility, phenotype (using triple-disc and induction tests), resistance genotype, emm genotyping (M typing) and phylogenetic(More)
BACKGROUND R-Mix, which contains a fresh mixture of two cell lines, Mv1Lu (mink lung cells) and A549 cells, has shown good sensitivity and specificity for respiratory virus culture. However, it has until recently only been available in North America, in part due to the shipping constraints associated with cell aging and the difficulty in providing these(More)
CONTEXT The Anyplex II HPV HR detection kit (Seegene Inc, Seoul, Korea) is a new, multiplex, real-time polymerase chain reaction assay to detect individual 14 high-risk (HR) human papillomavirus (HPV) types in a single tube. OBJECTIVE To evaluate the clinical performance of the HPV HR kit in predicting high-grade squamous intraepithelial lesions and(More)
