The present study characterised p53 mutations in 44 hepatocellular carcinomas (HCCs) from Chinese patients residing in a high-incidence area. Twelve point mutations (27%) were detected in tumour tissues using single-strand conformation polymorphism analysis followed by direct DNA sequencing. Remarkably, no mutations were observed at codon 249. This is in(More)
Although human amniotic fluid is an attractive source of multipotent stem cells, the potential of amniotic fluid stem cells (AFSCs) to differentiate into hepatic cells has not been extensively evaluated. In this study, we examined whether human AFSCs can differentiate into a hepatic cell lineage in vitro and in vivo. After being treated with cytokines(More)
Post-traumatic stress disorder (PTSD) is a debilitating anxiety disorder that may develop after an individual has experienced or witnessed a severe traumatic event. It has been shown that the 18 kDa translocator protein (TSPO) may be correlated with PTSD and that the TSPO ligand improved the behavioral deficits in a mouse model of PTSD. Midazolam, a ligand(More)
BACKGROUND Whether Tai Chi benefits patients with osteoarthritis remains controversial. We performed a meta-analysis to assess the effectiveness of Tai Chi exercise for pain, stiffness, and physical function in patients with osteoarthritis. METHODS A computerized search of PubMed and Embase (up to Sept 2012) was performed to identify relevant studies. The(More)
AIM Cancer stem cells have the capacity to initiate and sustain tumor growth. In this study, we established a CD44(+) colorectal cancer stem cell line with particular emphasis on its self-renewal capacity, enhanced tumor initiation and drug resistance. METHODS Fresh colon cancer and paired normal colon tissues were collected from 13 patients who had not(More)
OBJECTIVES To analyze the relationship between the fetus infection and HBV M, HBV DNA in amniotic fluid, umbilical cord blood, maternal blood and placenta, and to explore the mechanism of vertical transmission of HBV. METHODS Immunonetric assay and nucleic acid amplification hybri-comb were used. Both HBV M and HBV DNA were detected in amniotic fluid,(More)
In the present paper, nanocrystalline glass-ceramic of CaO-MgO-Al2O3-SiO2 system was produced by melting method. The CaO-MgO-Al2O3-SiO2 nanocrystalline glass-ceramic was measured by Raman spectroscopy in the temperature range from -190 to 310 degrees C in order to study the effect of temperature on the structure of this system nanocrystalline(More)
To detect the expression of RKIP, E-cadherin and NF-kB p65 in esophageal squamous cell carcinoma (ESCC) and study their correlations. Steptavidin-peroxidase (S-P) method was employed to detect the expressions of RKIP, E-cadherin and NF-kB p65 in ESCC tissues from 77 cases and paracancerous tissues from 77 cases. The correlations between their expressions(More)
Corticosterone inhibits the proliferation of hippocampal neural stem cells (NSCs). The removal of corticosterone-induced inhibition of NSCs proliferation has been reported to contribute to neural regeneration. Leptin has been shown to regulate brain development, improve angiogenesis, and promote neural regeneration; however, its effects on(More)
