The nickel and vanadium contents of nine institutional diets were determined by atomic absorption spectrometry with background correction. The following values were obtained for nickel: mean concentration, 0.27 +/- 0.02 microgram/g (dry weight); range, 0.19 and 0.41 microgram/g; mean intake, 165 +/- 11 microgram/day or 75 +/- 10 microgram/1000 cal.

BACKGROUND Non-invasive prenatal test of trisomy 21 (T21) is being researched using fetal specific epigenetic biomarkers present in maternal plasma. We applied a methyl-CpG binding domain-based protein (MBD) method based on epigenetic characteristics of fetal specific-methylated regions with a high CpG density in HLCS on chromosome 21 and RASSF1A on(More)
A semiquantitative chromatographic technique was developed and standardized using water/chloroform extracts of foods which are spotted onto heat-activated silica gel thin layer chromatographic (TLC) plates, run in butanol/acetic acid/ether/water, developed in acids anisaldehyde, and quantitated planimetrically using Purdy and Truter's formula. Clinically(More)
The objective of this study was to discover a panel of microRNAs (miRNAs) as potential biomarkers for noninvasive prenatal testing (NIPT) of trisomy 21 (T21) and to predict the biological functions of identified biomarkers using bioinformatics tools. Using microarray-based genome-wide expression profiling, we compared the expression levels of miRNAs in(More)
Non-invasive prenatal testing of trisomy 21 (T21) is being actively investigated using fetal-specific epigenetic markers (EPs) that are present in maternal plasma. Recently, 12 EPs on chromosome 21 were identified based on tissue-specific epigenetic characteristics between placenta and blood, and demonstrated excellent clinical performance in the(More)
OBJECTIVES The aim of this study was to investigate the clinical and biochemical profiles according to homeostasis model assessment of insulin resistance (HOMA-IR) in Korean polycystic ovary syndrome (PCOS) patients. METHODS In 458 PCOS patients diagnosed by the Rotterdam European Society for Human Reproduction and Embryology (ESHRE) criteria,(More)
BACKGROUND Quantification of cell-free fetal DNA by methylation-based DNA discrimination has been used in non-invasive prenatal testing of fetal chromosomal aneuploidy. The maspin (Serpin peptidase inhibitor, clade B (ovalbumin), member 5; SERPINB5) gene, located on chromosome 18q21.33, is hypomethylated in the placenta and completely methylated in maternal(More)
BACKGROUND Cell-free fetal DNA and cell-free total DNA in maternal circulation have been proposed as potential markers for noninvasive monitoring of the placental condition during the pregnancy. However, the correlation of and change in cell-free fetal DNA and cell-free total DNA in spontaneous abortion (SA) with fetal chromosomal aneuploidy have not yet(More)
A tapered plasmonic channel waveguide can be used for index sensing by spatial mapping of the scattering field intensity. A numerical simulation shows that this waveguide reflects the plasmonic channel waveguide mode at various points as the refractive index of an analyte changes, and a strong outgoing scattering wave appears at the reflection point. One(More)
Chronic alcohol consumption causes hepatic steatosis, which is characterized by a considerable increase in free fatty acid (FFA) and triglyceride levels. To identify the possible proteins involved in the progression to alcoholic hepatosteatosis, we performed proteomic analysis on livers of mice exposed to alcohol. 2D-based proteomic analysis revealed that(More)
