Circulating microRNA expression profiles may be promising biomarkers for diagnosis and assessment of the prognosis of cancer patients. Quantitative polymerase chain reaction (qPCR) is a sensitive technique for estimating expression levels of circulating microRNAs. However, there is no current consensus on the reference genes for qPCR analysis of circulating(More)
BACKGROUND Hyperbaric oxygen preconditioning (HBO) is a new method of ischemia preconditioning. In this study, we examined its effects on skin flap survival and the mechanisms involved. METHODS Thirty-six rats were divided into three groups: HBO preconditioning, control, and sham groups. An extended epigastric adipocutaneous flap based on the right(More)
BACKGROUND AND AIM Liver transplantation (LT) for hepatitis B virus (HBV)-related disease can be complicated by HBV recurrence. The aim of this study was to evaluate the risk factors, prophylaxis treatment, and histological characteristics of HBV recurrence after LT when using long-term, low-dose hepatitis B immunoglobulin (HBIG) plus nucleoside analog(More)
In patients with gastric cancer (GC), circulating microRNA-21 (miR-21) is overexpressed and may serve as a diagnostic biomarker. In the present study, it was hypothesized that the serum miR-21 expression levels were associated with prognosis in the patients with GC. The expression levels of serum miR-21 were measured using quantitative polymerase chain(More)
A simple method has been developed and validated for direct, sensitive detection and specific identification of 16S rRNA. We first report our direct investigation of discrimination efficiency for sequence variations in RNA using oligonucleotide microarrays assisted by base stacking hybridization, and demonstrate that the sequence variations of double base(More)
OBJECTIVE MicroRNAs (miRNAs) have potential as diagnostic biomarkers in cancer. Evaluation of the association between miRNA expression patterns and early detection of liver metastasis in colorectal cancer (CRC) has not been reported. METHODS We investigated the expression of metastasis-associated miRs-31, 335, 206, 141, 126, 200b, 200c, 21, Let7a, Let7b(More)
BACKGROUND In plastic surgery, skin damage induced by ischemia/reperfusion (I/R) is a multifactorial process that often occurs. Methane gas has been reported to be a new therapeutic gas for attenuating I/R injury. In this study, we assessed the effects of methane-rich saline (MRS) in regulating apoptosis on skin flap I/R injury. METHODS Male(More)
For most of the commonly used DNA chips, the probes are usually single-stranded oligonucleotides and the targets are double-stranded DNAs (dsDNAs). Only one strand of the DNA serves as the target while the other competes with the probes immobilized on the chip for the target and therefore is regarded as the interfering strand. In this report, a novel(More)
To investigate the potential adverse effects of mobile phone radiation, we studied reactive oxygen species (ROS), DNA damage and apoptosis in mouse embryonic fibroblasts (NIH/3T3) after intermittent exposure (5 min on/10 min off, for various durations from 0.5 to 8 h) to an 1800-MHz GSM-talk mode electromagnetic radiation (EMR) at an average specific(More)
BACKGROUND It is essential to clarify the interactions of hormones during the progression of human breast cancer. This study examined the effects of exogenous human leptin on estrogen receptor (ER) alpha and beta in human breast tumor tissue in a nude mouse xenograft model. METHODS We created nude mice xenografts of MCF-7 human breast cancer cells, and(More)
