Cyclooxygenase (COX), the rate-limiting enzyme in prostaglandins (PG) synthesis, exists in at least two isoforms, COX-1 and COX-2. COX-2 plays an important role in carcinogenesis, and overexpression may increase proliferation, inhibit apoptosis, and enhance the invasiveness of breast cancer cells. Polymorphisms in the regulatory regions of the COX-2 gene(More)
BACKGROUND The first outbreak of H5N1 highly-pathogenic avian influenza (HPAI) virus associated with several human deaths occurred in 1997 in Hong-Kong, China. While H5N1 virus infection in poultry workers has been studied in some detail, little is known about the environmental risk factors of the H5 avian influenza virus infection in China. METHODS A(More)
BACKGROUND & OBJECTIVE Transforming growth factor beta (TGFbeta) signaling pathway plays an important role in the genesis and progression of tumors through regulating cell proliferation and differentiation. The concentration of TGFbeta1 in plasma and the expression of TGFbeta receptor II (TGFbetaRII) are correlated to the development of certain tumors,(More)
OBJECTIVE To explore the relationship between total plasma homocysteine (tHcy) levels, dietary habits and susceptibility of gastric cancer (CGC) in Yangzhong and Yixing cities, the two high GC risk areas in Jiangsu province. METHODS A population-based case-control study was conducted including 391 histologically-confirmed adenocarcinoma GC cases and 608(More)
BACKGROUND The Ebola virus disease spread rapidly in West Africa in 2014, leading to the loss of thousands of lives. Community engagement was one of the key strategies to interrupt Ebola transmission, and practical community level measures needed to be explored in the field and tailored to the specific context of communities. METHODS First,(More)
OBJECTIVE To investigate the association of polymorphisms of CDT1 and GMNN gene, two important genes participating in DNA replication, with the risk of sporadic breast cancer. METHODS Using polymerase chain reaction-restriction fragment length polymorphism (PCR - RFLP) and the primer-introduced restriction analysis (PIRA)-PCR assay to genotype the CDT1(More)

In the title compound, [Co(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], the Co(II) ion is located on a twofold rotation axis and shows a distorted octa-hedral coordination configuration, defined by two N,O-bidentate 1H-imidazole-4-carboxyl-ate ligands in the equatorial plane and two water mol-ecules in the axial positions. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds(More)
OBJECTIVE To identify risk factors of ventilator-associated pneumonia (VAP) in pediatric intensive care unit (PICU). METHODS PubMed, Ovid, Web of Science, the Cochrane Library and references of retrieved articles were searched without language limitation. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by using both the(More)
