BACKGROUND The purpose of the meta-analysis is to explore the association between vitamin D receptor polymorphisms (including four gene loci: Taq-I, Bsm-I, Apa-I, and Fok-I) for susceptibility to periodontitis (either chronic [CP] or aggressive [AP]). Up to now, there has been only one systematic review focusing on this topic. We obtained some different(More)
Imprinted genes play important roles in mammalian growth, development and behavior. In this study, we obtained 1568 bp mRNA sequence of porcine DIO3 (deiodinase, iodothyronine, type III), and also identified its imprinting status during porcine fetal development. The complete open reading frame (ORF) encoding 278 amino acids. The porcine DIO3 mRNA was(More)
BACKGROUND Aspergillus fumigatus (A. fumigatus) is a ubiquitous saprophytic fungus responsible for the majority of invasive mold infections in patients undergoing chemotherapy, organ transplantation or with persistent neutropenia. This study aimed to determine the role of E-cadherin for adhesion and endocytosis of A. fumigatus blastospores in the human(More)
In this study, an affine registration algorithm with reference-omitted scheme and soft correspondence is proposed. It is an iterative method with two-step matching process at each iteration, named as forward matching and backward matching. Due to the introduction of backward matching, two sets of points are alternately to be reference set, such that the(More)
Point set matching is a common problem in many domains, such as medical image analysis, object recognition, 3D reconstruction, and motion tracking. Coherent point drift (CPD) appears as an efficient algorithm to align two point sets. It treated point set matching as a problem of Gaussian mixture density estimation. But there are four drawbacks in the CPD(More)
Influenza A affects a large population worldwide. Influenza virus evades immune responses via various mechanisms, including through the modification of the immune microenvironment. Influenza virus non‑structural protein 1 (NS1) encoded by the virus genome inhibits type I interferon (IFN) signaling pathways, which is essential for viral clearance. However,(More)
Diabetes mellitus is considered as a risk factor of Alzheimer's disease (AD), the front runner of neurodegenerative disorders. Streptozotocin (STZ) is a toxin for pancreatic β-cell, which can construct a model of insulin deficient diabetes through intraperitoneal or intravenous injection. A model generated by intracerebroventricular STZ (icv-STZ) also shows(More)
In recent years, along with the wide application of organ transplantation and immunosuppressive agents, as well as the abuse of broad spectrum antibiotics, the incidence of invasive fungal infections has been increasing gradually. The present study aimed to identify novel biomarkers in cells infected with Aspergillus fumigatus. Human umbilical vein(More)
This paper proposes a new affine registration algorithm for 2D point matching. It is a two-step iterative registration algorithm by soft weight assignment based on bidirectional distance. At each iteration, the affine transformation is updated by two optimization steps, in which the model data and the test data are matched from each other respectively. By(More)
BACKGROUND Influenza A virus infection and its complications effect a large population worldwide. Endothelial cells are an important component in lung inflammation caused by influenza A virus infection. The roles of endothelial sphingosine 1-phophate receptor 1 (S1PR1) in the regulation of molecules involved in leukocyte recruitment during influenza A virus(More)
