Superoxide dismutases (SODs) are vital components that defend against oxidative stress through decomposition of superoxide radical. Escherichia coli contains two highly homologous SODs, a manganese- and an iron-containing enzyme (Mn-SOD and Fe-SOD, respectively). In contrast, a single Mn-SOD is present in Bacillus subtilis. In E. coli, the absence of SODs(More)
AIMS This report describes the baseline characteristics of patients in the Reduction of Events with Darbepoetin alfa in Heart Failure trial (RED-HF) which is testing the hypothesis that anaemia correction with darbepoetin alfa will reduce the composite endpoint of death from any cause or hospital admission for worsening heart failure, and improve other(More)
The adherence of Helicobacter pylori to gastric epithelial cells is required for prolonged persistence in the stomach and for induction of injury. Here, we first reported a new role of the receptor for advanced glycation end-products (RAGE) on the adherence of H. pylori to gastric epithelial cells, assessed by different methods and binding to immobilized(More)
The prevalence of Helicobacter pylori infection and the gastric cancer mortality rate in Chile are remarkably high. This study identified some virulence-associated genes in 78 H. pylori clinical isolates from dyspeptic patients from the Region del Maule, which is the region with the higher gastric cancer mortality rate in the country. The cagA, vacA and(More)
OBJECTIVES To determine the distribution of lipoprotein(a) levels and prevalence of hyperLp(a) in diabetes mellitus type I (IDDM). To analyze the effect of glycemic control and microalbuminuria on Lp(a) levels. METHODS Cross-sectional study of 263 subjects with IDDM with a mean age of 19.2 +/- 11.6 years and an evolutive course of 6.3 +/- 6.5 years. Apart(More)
The Broad-Complex (BR-C) of D. melanogaster, mapping at the 2B5 early ecdysone puff, mediates ecdysone-induced processes. We present here the transcriptional analysis of the locus in both wild type and representative mutants. Two well defined regions are transcribed, only one of which has a pattern consistent with the proposed 2B5 located BR-C function. The(More)
The monocyte-macrophage lineage shows a high degree of diversity and plasticity. Once they infiltrate tissues, they may acquire two main functional phenotypes, being known as the classically activated type 1 macrophages (M1) and the alternative activated type 2 macrophages (M2). The M1 phenotype can be induced by bacterial products and interferon-γ and(More)
