Five hundred four fecal specimens, collected between 2004 and 2006 from young children with acute diarrhea, were screened for rotavirus by ELISA with VP6-specific antibody. Of these samples, 394 (78.2%) were confirmed as group A rotavirus and they underwent G- and P typing using a combination of ELISA, RT-PCR, and sequence analysis methods. The dominant(More)
The human rotavirus G1P[8] strain is one of the most common rotaviruses worldwide, including Korea. Six Korean G1P[8] human rotaviruses, isolated using cell culture techniques, were characterized on the basis of sequence differences in VP7, VP4, VP6, and NSP4 genes to elucidate the evolutionary relationships in the community. All strains had a long RNA(More)
Perinatal hypoxic ischemia injury is a common cause of morbidity and mortality in neonates. Physical exercise may ameliorate neurological impairment by impeding neuronal loss following various brain insults. In the present study, the effect of treadmill exercise on sensory-motor function in relation with hippocampal apoptosis following hypoxic ischemia(More)
Huntington's disease is a chronic neurodegenerative disorder inherited in an autosomal dominant fashion, and characterized as involuntary movement. Quinolinic acid has been used to produce an animal model of Huntington's disease. In the present study, the effect of treadmill exercise on spatial-learning ability and motor coordination focusing on the(More)
The accuracies of relative gene expressions as determined by quantitative real-time polymerase chain reaction are largely dependent on the variabilities of the reference genes used. Validation of the stabilities of reference genes under experimental conditions is an essential initial step for comparative studies on the expression levels of target genes in(More)
The purpose of this study was to investigate the impact of the duration-dependence of the one bout treadmill exercise on cell proliferation, stress, and central fatigue in rats. The animals were randomly divided into five groups: the non-exercise group, 1-h exercise group, 2-h exercise group, 4-h exercise group, and 6-h exercise group. The exercise load(More)
Bacillus anthracis has four plasmid possible virulence genotypes: pXO1+/pXO2+, pXO1+/pXO2-, pXO1-/pXO2+ or pXO1-/pXO2-. Due to the lack of a specific chromosomal marker for B. anthracis, differentiation of the pXO1-/pXO2- form of B. anthracis from closely related Bacillus cereus group species is difficult. In this study, we evaluate the ability of sspE,(More)
BACKGROUND & AIMS Hepatitis B virus (HBV) genotype C infection is associated with progression of hepatocellular carcinoma (HCC). Specific mutations of the HBV surface (S) gene have been reported to contribute to the development of HCC. In this study, novel nucleotide changes (sW182*) that result in a premature stop at codon 182 in the S gene of genotype C(More)
AIM Our previous study showed for the first time that shikonin, a natural compound isolated from Lithospermun erythrorhizon Sieb. Et Zucc, inhibits adipogenesis and fat accumulation. This study was conducted to investigate the molecular mechanism of the anti-adipogenic effects of shikonin. MAIN METHODS Gene knockdown experiments using small interfering(More)
Depression is a major cause of disability and one of the most common public health problems. In the present study, antidepressive effect of treadmill exercise on chronic mild stress (CMS)-induced depression in rats was investigated. For this, sucrose intake test, immunohistochemistry for 5-bromo-2'-deoxyuridine, terminal deoxynucleotidyl(More)
