Bacteria are thought to contribute to the pathogenesis of necrotizing enterocolitis (NEC), but it is unknown whether their interaction with the epithelium can participate in the initiation of mucosal injury or they can act only following translocation across a damaged intestinal barrier. Our aims were to determine whether bacteria and intestinal epithelial TLR4 play roles in a well-established ...

Bacterial lipopolysaccharide and some cytokines can activate macrophages to secrete nitric oxide. Macrophage-derived nitric oxide is a key cytotoxic factor for microbicidal and tumoricidal processes. We report here that a monoclonal antibody specific for beta interferon inhibited lipopolysaccharide-induced nitric oxide production in thioglycolate-elicited C3HeB/FeJ peritoneal macrophages and ma...

Administration by stomach tube of 7,12-dimethylbenz(aV anthracene (DMBA) (30 mg/100 gm body weight) in oil caused a decrease in the ovarian weights of C57BL/6J, C3D2F!, CAFl5 B6AFj, B6D2F,, and C57BL/6J X C3HeB/FeJ mice, but it did not affect the ovarian weights of C3HeB/FeJ X NZY mice or of Sprague-Dawley or Fischer rats. DMBA treatment also eliminated the ovarian weight gain, which normally i...

Let $\varphi=\{\varphi_k\}_{k=-\infty}^\infty$ denote the extended Takenaka--Malmquist system on unit circle $\mathbb T$ and let $\sigma_{n,\varphi}(f),$ $f\in L^1(\mathbb T)$, be Fej\'er-type operator based $\varphi$, introduced by V. N. Rusak. We give convergence criteria for $\sigma_{n,\varphi}(f)$ in Banach space $X(\mathbb T):=L^p(\mathbb T)\vee C(\mathbb $p\ge 1$. Also we prove Voronovska...

∗ Autor para correspondência. Correio eletrónico: [email protected] (A.R. Araújo). Na radiografia de tórax observou-se cardiomegalia, com índice cardiotorácico de 60%. O eletrocardiograma mostrou ondas Q > 3 mm em DI, aVL e V7 e inversão da onda T de V5-V7, padrão sugestivo de enfarte do miocárdio. O ecocardiograma transtorácico revelou dilatação e disfunção global do ventrículo esqu...

In this paper, we propose a programming language called NextEJ. NextEJ is a smooth combination of a role-based language EpsilonJ and context activation mechanisms provided by COP languages. It supports all the features of the Epsilon model such as dynamic object-role binding and unbinding, and encapsulation of collaboration of roles as a context that can be defined as a reusable module. Further...
