BACKGROUND AND AIMS Activins belong to the transforming growth factor-beta superfamily. Recent studies have shown that activin and its natural antagonist, follistatin, are involved in tissue repair and inflammatory processes. The aim of this study was to determine whether neutralization of activins with follistatin would have an in vivo anti-inflammatory(More)
PURPOSE The aim of this review of the literature was to evaluate the effectiveness of anesthetics in protecting the heart against myocardial ischemia-reperfusion injury. SOURCE Articles were obtained from the Medline database (1980-, search terms included heart, myocardium, coronary, ischemia, reperfusion injury, infarction, stunning, halothane,(More)
BACKGROUND & AIMS The cytokines interleukin (IL)-4 and IL-13 have pleiotropic effects on a variety of cell types and impact both pathologic changes and tissue remodeling. The aim of this study was to clarify the roles of IL-13 receptor alpha2 (IL-13Ralpha2), which is the high-affinity decoy receptor for IL-13, in gastrointestinal tract epithelial cell(More)
Our past studies showed that Peyer's patches were required for the induction of oral tolerance to the protein antigen ovalbumin (OVA), but not to the hapten 2,4,6-trinitrobenzene sulfonic acid (TNBS). In the present study, the effects of immunosenescence on oral tolerance induction were assessed with these two toleragens. Significant reductions in(More)
Cholera toxin (CT) is a potent adjuvant; however, the mechanism for its ability to enhance mucosal immunity has not been fully elucidated. We report here that CT exerts its adjuvant properties by signaling through the GM1 ganglioside receptor. When ganglioside-defective mice were given the antigen (Ag) ovalbumin (OVA) with CT by the oral route, CT failed to(More)
A low dose of morphine, given intrathecally is an effective postoperative analgesic technique and is widely used in cesarean section. Delayed respiratory depression is the most feared side effect of this technique. However, this side effect has not been thoroughly reported in the obstetric population. The aim of this study was to describe respiratory(More)
BACKGROUND & AIMS T helper (Th) 1 and Th2 cell subsets significantly influence the pathological features of inflammation in the gastrointestinal tract in a distinct manner. It is now established that the transfer of CD4(+)CD45RB(Hi) (RB(Hi)) T cells to either severe combined immunodeficient (SCID) or recombinase activation gene 2-deficient (RAG(-/-)) mice(More)
BACKGROUND p51 (p73L/p63/p40/KET), a recently isolated novel p53 homologue, binds to p53-responsive elements to upregulate some p53 target genes and has been suggested to share partially overlapping functions with p53. p51 may be a promising candidate target molecule for anti-cancer therapy. METHODS In this study, we adenovirally transduced p51A cDNA into(More)
Despite the huge number of colonized Gram-negative bacteria in the colon, the normal colon maintains its homeostasis without any excessive immune response. To investigate the potential mechanisms involved, human colonic lamina propria mononuclear cells (LPMCs) obtained from uninflamed mucosa were cultured with lipopolysaccharide (LPS) prepared from(More)
Near-infrared spectrophotometry (NIRS) is a new technique that allows continuous non-invasive monitoring of tissue oxygenation and haemodynamics in the brain. We used NIRS in various types of paediatric epileptic seizures in order to understand the pathophysiology of epileptic seizures in childhood epilepsy. This study examined 15 children ranging in age(More)
