Inflammatory bowel disease (IBD), particularly Crohn's disease, frequently causes intestinal fibrosis that ultimately leads to formation of strictures requiring bowel resection. Currently there is no effective antifibrotic therapy available for this disease. Pirfenidone is a small compound that has a broad spectrum of antifibrogenic effect and has been used(More)
This study aimed to identify the effect of β-caryophyllene (BCP) pretreatment and elucidate the Nrf2/HO-1 signaling mechanism after focal cerebral ischemia-reperfusion (I-R) injury in rats. Adult male Sprague–Dawley rats were randomly assigned to the sham-operated group, I-R group and BCP pretreated I-R group. At 24 h after reperfusion, neurological(More)
OBJECTIVE To investigate the consequences of histone deacetylase inhibition by histone deacetylase inhibitor valproic acid and IκB kinase/nuclear factor-κB signaling blockade by IκB kinase inhibitor BAY11-7082 on (microvascular) endothelial cell behavior in vitro as well as in mice subjected to hemorrhagic shock/resuscitation in vivo. DESIGN Prospective,(More)
Acute lower gastrointestinal bleeding (ALGIB) is a rare but potentially life-threatening complication of Crohn disease (CD). Thus far, few studies of ALGIB in the context of CD have been published, most of which were case reports with limited value. We aimed to explore the prevalence of ALGIB in CD patients, evaluate risk factors for hemorrhagic CD and its(More)
Circulatory shock and resuscitation are associated with systemic hemodynamic changes, which may contribute to the development of MODS (multiple organ dysfunction syndrome). In this study, we used an in vitro flow system to simulate the consecutive changes in blood flow as occurring during hemorrhagic shock and resuscitation in vivo. We examined the kinetic(More)
Spleen tyrosine kinase (Syk), a member of Syk family of cytoplasmic non-receptor tyrosine kinases, is a key component of B cell receptor signaling and regulates multiple physiological functions of B lymphocytes in vertebrates. In the current study, a Syk homologue was identified in the lamprey Lampetra japonica (Lj-Syk). The cDNA fragment of Lj-Syk contains(More)
BACKGROUND The role of human papillomavirus (HPV) may be involved in the development of esophageal cancer (EC) and the polymorphic immune response gene transporter associated with antigen processing (TAP) may be involved in HPV persistence and subsequent cancer carcinogenesis. The current study aims to provide association evidence for HPV with EC, to(More)
