The biological behavior of childhood B-lineage acute lymphoblastic leukemia (B-ALL) is different from that of adults. We performed a comprehensive analysis of the deletion and the methylation profile of CDKN2A (hereafter identified separately as p16 and p14, for the different proteins encoded) and CDKN2B (hereafter p15) in 91 newly diagnosed B-ALL patients(More)
Since accurate identification of species is necessary for proper treatment of Acinetobacter infections, we compared the performances of 4 bacterial identification methods using 167 Acinetobacter clinical isolates to identify the best identification method. To secure more non-baumannii Acinetobacter (NBA) strains as target strains, we first identified(More)
Although the presence of decreased plasma fibrinogen has been regarded as an indicator of ongoing disseminated intravascular coagulation (DIC), fibrinogen, which is one of the acute phase reactants, is often increased in the patients with DIC. We investigated the diagnostic and prognostic utility of a new parameter [the fibrinogen/C-reactive protein (CRP)(More)
Trisomy 8 and trisomy 1q are the most frequent chromosomal abnormalities in Korean patients with myelodysplastic syndrome (MDS). MicroRNA (miRNA) deregulation is involved in the development of hematological malignancies, including MDS, and cancer-associated genomic regions are known to encode miRNAs. The aim of the present study was to investigate the(More)
We propose a learning method for the ADALINE. The proposed method exploits fuzzy logic system for automatic tuning of the weights of the ADALINE. The inputs of the fuzzy logic system are error and change of error, and the output is the weight variation. We used same membership functions and different scaling factor for each weights. In order to verify the(More)
Death receptor 3 (DR3, TNFRSF25) is expressed by activated lymphocytes and signaling by its ligand, TL1A, enhances cytokine expression and proliferation. Recent studies show that DR3 is also present on murine type 2 innate lymphoid cells (ILC2s). Here, we show that DR3 is expressed by IL-22-producing human group 3 innate lymphoid cells (ILC3s). Stimulation(More)
It is well established that TGF-β1 and retinoic acid (RA) cause IgA isotype switching in mice. We recently found that lactoferrin (LF) also has an activity of IgA isotype switching in spleen B cells. The present study explored the effect of LF on the Ig production by mouse peritoneal B cells. LF, like TGF-β1, substantially increased IgA production in(More)
Thrombomodulin has a central role in the regulation of coagulation through its abilities to promote generation of the potent anticoagulant activated protein C. Because little is known about monocyte thrombomodulin expression and its regulatory mechanism by lipopolysaccharide, we investigated the effect of lipopolysaccharide on monocyte's thrombomodulin(More)
We used pyrosequencing, peptide nucleic acid (PNA)-clamping polymerase chain reaction (PCR), and real-time PCR to detect the BRAF V600E mutation and to investigate the prognostic effect of the BRAF V600E mutation in paraffin block specimens from 100 patients diagnosed with papillary thyroid carcinoma. Positive rates of PNA-clamping PCR, real-time PCR, and(More)
We had previously reported the association of the NQO1*2/*2 polymorphism with a decreased risk for multiple myeloma (MM) in Koreans (odds ratio, OR, 0.24; 95% confidence interval, CI, 0.01-0.68). The associations of polymorphisms of other metabolizing enzymes (CYP1A1, GSTM1 and GSTT1) with the MM risk were investigated in 116 Korean MM patients and 176(More)
