Clonorchis sinensis is still a common parasite in South Korea. An enzyme-linked immunosorbent assay (ELISA) was developed to replace the usual intradermal test, and its performance in an area of endemicity was evaluated. From 2004 to 2006, 182 adults were included. The patient group consisted of 51 adults; 43 patients showed fluke eggs by microscopy, and 8(More)
We validated candidate biomarkers using circulating miRNAs by analyzing serum miRNA concentrations from patients with gastric cancer (GC) to predict lymph node (LN) metastasis. In a pilot study, serum levels of miR-21, miR-27a, miR-106b, miR-146a, miR-148a, miR-223, and miR-433 were compared in 10 healthy donors, 16 LN-positive patients with GC, and 15(More)
BACKGROUND PCR is a widely used method for rapid and accurate diagnosis of mycobacteriosis. The sensitivity and specificity of a real time PCR kit newly developed in Korea were evaluated for detecting mycobacteria in respiratory specimens. METHODS One hundred twenty nine Mycobacterium tuberculosis (TB) culture positive respiratory specimens (82 AFB stain(More)
We report a case of acquired thrombotic thrombocytopenic purpura (TTP) triggered by influenza A virus subtype H1N1 infection. In December 2010, a 27-year-old man was diagnosed with pneumonia from influenza A virus infection at a local clinic. Two days later, he was admitted to our hospital because of a worsening condition and unexplained thrombocytopenia.(More)
We describe a 23-year-old retired military officer who was immunocompetent but diagnosed with hemophagocytic syndrome (HPS) by Plasmodium vivax infection. Initially, the patient was suspected to have toxic hepatitis related to heavy drinking. But abnormal hematologic findings required a further bone marrow examination and the diagnosis of HPS was made.(More)
HIF-1alpha is a transcription factor that acts as a master regulator of gene expression induced by hypoxia. Recent studies have demonstrated that the potent inflammatory factor, lipopolysaccharide (LPS), can also activate HIF-1alpha in myeloid cells. However, the molecular mechanisms at the transcriptional level of HIF-1alpha induction by LPS remained(More)
We evaluated high-resolution melting (HRM) curve analysis as a tool for detecting rifampin (RIF) and isoniazid (INH) resistance in Mycobacterium tuberculosis in an accurate, affordable, and rapid manner. Two hundred seventeen M. tuberculosis clinical isolates of known resistance phenotype were used. Twenty-nine known rpoB mutant DNAs, including rare(More)
BACKGROUND Although hepatitis B surface antigen (HBsAg) rapid test based on immunochromatographic assay (ICA) is now widely used, the test has not been evaluated sufficiently enough to validate its performance. Thus, it is important to summarize the clinical performance of the test kits. In this study, we performed meta-analysis for the performance of the(More)
Granulicatella adiacens is a catalase-negative, oxidase-negative, facultatively anaerobic, Gram-positive coccus [1]. This bacterium is considered nutritionally variant streptococci (NVS) because of its requirement for pyridoxal, L-cysteine, or additional nutrients, such as sulfhydryl compounds, for growth [2]. G. adiacens can grow well on culture medium(More)
The Di(a) antigen is well known as one of the antigens with low incidence among Caucasians; however, it has been discovered with a relatively higher incidence among Mongoloid populations. Thus, it has been speculated that the incidence of unexpected antibody against the Di(a) antigen might be relatively higher among these populations. Hemolytic transfusion(More)
