Recently, novel hybrid thiol peroxidase (TPx) proteins fused with a glutaredoxin (Grx) were found from some pathogenic bacteria, cyanobacteria, and anaerobic sulfur-oxidizing phototroph. The phylogenic tree analysis that was constructed from the aligned sequences showed two major branches. Haemophilus influenzae TPx.Grx was grouped in one branch as a 1-Cys(More)
This study was aimed at developing a predictive model for assessing the breast cancer risk of Korean women under the assumption of differences in the risk factors between Westerners and Koreans. The cohort comprised 384 breast cancer patients and 2 control groups: one comprising 166 hospitalized patients and the other comprising 104 nurses and teachers. Two(More)
Microarray-based comparative genomic hybridization (array CGH) is a high-resolution and comprehensive method for detecting both genome-wide and chromosome-specific copy-number imbalance. We have developed an array CGH analysis system (consisting of an array CGH chip plus its exclusive analysis software) for constitutional genetic diagnosis and have(More)
The objective of this study was to identify the main risk factors for gastric cancer in Koreans through the development of a predictive model by multivariate logistic regression analysis that could aid the development of specific guidelines for early detection. We conducted a case control study to identify the risk factors for gastric cancer. The cohorts(More)
A 12b 2MS/s cyclic ADC achieves low power consumption with a single-ended rail-to-rail input signal range of 3.3Vp-p. The proposed voltage reference scheme directly employing power supply voltages implements an offset voltage less than 1mV without well-known calibration and trimming techniques. The prototype ADC in a 0.18mm CMOS technology demonstrates the(More)
Only limited information is available in the research area on the effect of elevated CO2 concentration ([CO2]) and air temperature (Tair) on the fertilizer N uptake by rice. This study was conducted to investigate changes in rice uptake of N derived from fertilizer (NDFF) and soil (NDFS) as well as fertilizer N uptake efficiency (FUE) with elevated [CO2](More)
In this study, we investigated whether vitrification of an embryo by attachment to the inner surface of a plastic straw, which requires a small volume of vitrification solution, improves the survival of thawed embryos. In vitro-produced Korean native cattle blastocysts were randomly assigned into four groups: (1) blastocysts attached to the inner surface of(More)
