Candida sp.99-125 lipase was suitable for transesterification of fats and oils to produce fatty acid methyl ester. The adsorption of Candida sp.99-125 lipase onto the fiber-like SBA-15 mesoporous material has been studied. The unaltered structural order of the fiber-like SBA-15 before and after the adsorption has been confirmed by FT-IR, SEM and N2(More)
Polymorphisms in 3' untranslated region (UTR) of cancer-related genes might affect their regulation by microRNAs (miRNAs) and thereby contribute to carcinogenesis. In this study, we screened single nucleotide polymorphisms (SNPs) in 3' UTR of cancer-related genes and investigated their effects on risk of lung cancer. First, we genotyped seven SNPs in a(More)
To improve the performance of motion estimation in video coding, we propose a novel search algorithm, which utilizes the global search ability of particle swarm optimization (PSO) and the local search ability of simplex method (SM).According to the center-biased and temporal-spatial correlation features of motion vector and the global randomness of PSO, the(More)
Lysyl oxidase (LOX) has been reported to regulate tumor metastasis and has been found to involve in modification of extracellular matrix (ECM) in the context of tumorigenesis. The aim of this study is to determine the prognostic significance of LOX in non-small cell lung cancer (NSCLC) patients and to examine the correlation between LOX expression and ECM(More)
BACKGROUND Injurious inflammatory response is critical to the development of lung ischemia/reperfusion injury (LIRI). The cytochrome P450 epoxygenase 2J2 (CYP2J2) metabolizes arachidonic acid to epoxyeicosatrienoic acids (EETs), which exert an anti-inflammatory effect on the cardiovascular system. We therefore cytochrome hypothesized that CYP2J2(More)
Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) such as gefitinib are clinically effective treatments for non-small cell lung cancer (NSCLC) patients with EGFR activating mutations. However, therapeutic effect is ultimately limited by the development of acquired TKI resistance. MicroRNAs (miRNAs) represent a category of small(More)
To assess novel liquid chromatography/mass spectrometric methods for measuring oxidative damage to nucleic acids and lipids, we compared urinary excretion of 8-hydroxy-2'-deoxyguanosine (8-OHdG), 5-hydroxymethyl-2'-deoxyuridine (5-OHmU), and 8-hydroxyguanosine (8-OxoG), and an isoprostane, 8-iso-prostaglandin F(2)alpha (IsopF(2)alpha) in 234 healthy men (n(More)
Published literatures on the prognostic value of hypoxia-inducible factor-1α (HIF-1α) overexpression in esophageal squamous cell carcinoma (ESCC) are conflicting and heterogeneous. We performed a meta-analysis to more precisely evaluate the clinicopathological and prognostic value of HIF-1α in patients with ESCC. Searches were applied to MEDLINE, Pubmed,(More)
Epidermal growth factor receptor (EGFR) mutation status is the best predictor of patient response to treatments with tyrosine kinase inhibitors in primary lung adenocarcinoma and is typically analyzed by DNA-based techniques, such as direct DNA sequencing and allele-specific PCR. Recently, however, two mutation-specific antibodies against delE746-A750 in(More)
BACKGROUND Cytochrome P450 epoxygenase 2J2 (CYP2J2) metabolizes arachidonic acids to epoxyeicosatrienoic acids (EETs). EETs exert various biological effects, including anti-inflammatory, anti-apoptotic, pro-proliferation, pro-angiogenesis, anti-oxidation, and anti-fibrosis effects. However, little is known about the role of CYP2J2 and EETs in lung(More)
