Rates of metallo-beta-lactamase and 16S rRNA methylase production were investigated in 51 imipenem-resistant Pseudomonas aeruginosa clinical isolates collected from hospitals in São Paulo, Brazil. Of them, 57% and 75% produced SPM-1 and RmtD, respectively. Of note, 51% produced both enzymes, suggesting that their coproduction is already common in this geographic area.

Type 1 diabetes (T1D) is a T cell mediated autoimmune disease. During the pathogenesis, patients become progressively more insulinopenic as insulin production is lost, presumably this results from the destruction of pancreatic beta cells by T cells. Understanding the mechanisms of beta cell death during the development of T1D will provide insights to generate an effective cure for this disease....

BACKGROUND/AIM The aim of this study was to determine the molecular characteristics and antibiotic resistance of 13 (10 inpatient and three outpatient) Acinetobacter baumannii beta-lactamase-producing isolates collected in Bosnia and Herzegovina between December 2009 and May 2010. MATERIALS AND METHODS Susceptibility testing was performed by disk diffusion and broth microdilution methods. The...

introduction: leptin is an adipocyte-derived hormone. exogenous leptin allows the recovery of the reproductive function. in humans, leptin correlates positively with the body mass index (bmi). the aim of this study was to investigate the association of leptin with the toxic effects of iron overload. methods: 219 major beta thalassemic patients (119 men, 100 women) and 137 non thalassemic indivi...

Background: &beta-thalassemia is the most common monogenic disorder in human. The (CT) polymorphism at -158 upstream region of the &gammaG-globin gene and pharmacological factors such as hydroxyurea have been reported to influence &gamma-globin gene expression and the severity of clinical symptoms of &beta-thalassemia. Methods: In the present study, 51 &beta-thalassemia intermediate patients w...
