From August 1978 to December 1983, 51 insulin-dependent diabetic patients with end-stage renal disease were selected for treatment by continuous ambulatory peritoneal dialysis. There were 27 male and 24 female patients, with a mean age of 52.3 +/- 13.5 years. Forty-five patients dialyzed themselves by continuous ambulatory peritoneal dialysis and six were(More)
The in vitro antimicrobial activities of pannarin, a depsidone isolated from lichens, collected in several Southern regions of Chile (including Antarctica), was evaluated alone and in combination with five therapeutically available antibiotics, using checkerboard microdilution assay against methicillin-resistant clinical isolates strains of Staphylococcus(More)
The frequency of Klebsiella pneumoniae carbapenemase-producing K. pneumoniae is increasing in Italian hospitals and poses an emerging threat to the management of infections in hospitalized patients. In this study, we report a detailed molecular characterization of a K. pneumoniae subsp. pneumoniae KP1/11 isolate from the decubitus ulcer of a hospitalized(More)
The purpose of this study was to investigate the presence and distribution of integron-carrying isolates among Enterobacteriaceae resistant to β-lactam antibiotics collected from a wastewater effluent of the city of L'Aquila (Italy). A total of 471 Enterobacteriaceae were collected during a period of 2 years (2005-2006). The presence and distribution of(More)
The in vitro antimicrobial activities of usnic acid were evaluated in combination with five therapeutically available antibiotics, using checkerboard microdilution assay against methicillin-resistant clinical isolates strains of Staphylococcus aureus. MIC₉₀, MIC₅₀, as well as MBC₉₀ and MBC₅₀, were evaluated. A synergistic action was observed in combination(More)
The in vitro antimicrobial activities of five compounds isolated from lichens, collected in several Southern regions of Chile (including the Chilean Antarctic Territory), were evaluated alone and in combination with five therapeutically available antibiotics, using checkerboard microdilution assay against methicillin-resistant clinical isolates strains of(More)
Clozapine is the most effective antipsychotic to date, but its benefits are counterbalanced by the risk of severe hematological effects. In this study, we analyzed whether clozapine inhibits polymorphonuclear (PMN) leukocyte chemotaxis. We found that clozapine, within the therapeutic concentration range, potently and selectively inhibits PMN chemotaxis(More)
The role of RecA protein in bacterial resistance to antibiotics makes this protein attractive from a pharmacological point of view. In this study we demonstrate that curcumin is able to inhibit the SOS response in Escherichia coli induced by levofloxacin. The blaTEM-1 gene has been placed under the control of the LexA-binding box and used as reporter gene.(More)
In this study 114 extensively drug-resistant Acinetobacter baumannii clinical isolates were characterized. The strains were collected at L'Aquila Hospital after the earthquake in L'Aquila city (central Italy) on the 6th of April 2009. The genes blaOXA-23 and blaOXA-51 were detected in all clinical isolates analyzed, whereas blaTEM-1 allele was detected in(More)
Evolution of visual function was assessed in 43 insulin-dependent diabetic (IDD) patients treated by maintenance haemodialysis (MH) for a cumulative duration of 1248 patient-months. At start of MH, 23 patients (46 eyes) still had good vision, 20 patients (40 eyes) were blind. All 40 blind eyes had severe proliferative retinopathy (PR) with additional(More)
