Interleukin-17A and interleukin-17F (IL-17A and IL-17F) are candidate genes for chronic inflammatory disease. We investigated the association between IL17A/F gene polymorphisms and susceptibility to and clinical features of inflammatory bowel disease (IBD). A total of 270 ulcerative colitis (UC) patients, 82 Crohn’s disease (CD) patients and 268 healthy(More)
BACKGROUND Previous studies implicated that IL23R and IL17 genes play an important role in autoimmune inflammation. Genome-wide association studies have also identified multiple single nucleotide polymorphisms (SNPs) in the IL23R gene region associated with inflammatory bowel diseases. This study examined the association of IL23R and IL17A gene SNPs with(More)
The cone theory andmonotone iterative technique are used to investigate theminimal nonnegative solution of nonlocal boundary value problems for second-order nonlinear impulsive differential equations on an infinite interval with an infinite number of impulsive times. All the existing results obtained in previous papers on nonlocal boundary value problems(More)
AIM To investigate the involvement of Dickkopf-1 expression in gastric cancer. METHODS Dickkopf-1 mRNA and protein expression were determined by real-time quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) and immunohistochemistry in specimens of primary cancer and their adjacent noncancerous tissues in gastric cancer patients.

In this paper, proper orthogonal decomposition (POD) is used for model reduction of mixed finite element (MFE) for the nonstationary Navier–Stokes equations and error estimates between a reference solution and the POD solution of reduced MFE formulation are derived. The basic idea of this reduction technique is that ensembles of data are first compiled from(More)

Zinc finger E-box binding homeobox factor 1 (ZEB1), as a crucial mediator of “epithelial-mesenchymal transition,” contributes to malignant progression of various epithelial tumors. However, its involvement in human esophageal squamous cell carcinoma (ESCC) remains unclear. In order to investigate the expression pattern of ZEB1 in ESCC tissues and evaluate(More)
Based on the renowned additive operator splitting (AOS) schemes that ensure equal treatment of all coordinate axis, accelerated AOS schemes for solving regularized Perona-Malik (P-M) equation are presented. These ameliorated AOS schemes are stable unconditionally, consistent with nonlinear parabolic equations under certain circumstance and demonstrate a(More)
