The crucial role played by the myofibroblast in wound healing and pathological organ remodeling is well established; the general mechanisms of extracellular matrix synthesis and of tension production by this cell have been amply clarified. This review discusses the pattern of myofibroblast accumulation and fibrosis evolution during lung and liver fibrosis(More)
BACKGROUND & AIMS The ligand-dependent transcription factor peroxisome proliferator-activated receptor gamma (PPARgamma) is expressed in hepatic stellate cells (HSC), and its transcriptional activity is reduced during cell transdifferentiation in culture. PPARgamma transcriptional activation decreases platelet-derived growth factor-induced proliferation and(More)
A genome-wide association screen for primary biliary cirrhosis risk alleles was performed in an Italian cohort. The results from the Italian cohort replicated IL12A and IL12RB associations, and a combined meta-analysis using a Canadian dataset identified newly associated loci at SPIB (P = 7.9 x 10(-11), odds ratio (OR) = 1.46), IRF5-TNPO3 (P = 2.8 x(More)
OBJECTIVE We sought to assess short- and long-term prognosis of syncope and associated risk factors. BACKGROUND Syncope is a common clinical event, but our knowledge of its short-term outcome is largely incomplete. Further, it is unknown whether hospital admission might positively affect a patient's syncope prognosis. METHODS We screened 2,775(More)
Fatty acids are ligands for the peroxisome proliferator-activated receptor alpha (PPAR alpha). Fatty acid levels are increased in liver during the metabolism of ethanol and might be expected to activate PPAR alpha. However, ethanol inhibited PPAR alpha activation of a reporter gene in H4IIEC3 hepatoma cells expressing alcohol-metabolizing enzymes but not in(More)
Peroxisome-proliferator activator receptor γ (PPARγ) is a nuclear receptor of central importance in energy homeostasis and inflammation. Recent experimental pieces of evidence demonstrate that PPARγ is implicated in the oxidative stress response, an imbalance between antithetic prooxidation and antioxidation forces that may lead the cell to apoptotic or(More)
OBJECTIVE : Evaluate HIV-1 subtype B integrase gene evolution in patients failing raltegravir (RAL)-based savage regimens by clonal analysis of the replicating viral quasispecies. DESIGN : Seven triple class failure HIV-1 (subtype B)-infected patients, followed at San Raffaele Hospital and enrolled in the RAL Expanded Access Program (MK0518-023), were(More)
BACKGROUND The role of laparoscopic surgery for the treatment of gastric cancer is still controversial, particularly in terms of oncologic efficacy. The aim of this study was to compare short-term outcomes of laparoscopic and open resection for gastric cancer at a single Western institution. SUBJECTS AND METHODS This study was designed as a matched cohort(More)
Several strains of Penicillium are used for the production of mold-ripened cheeses, and some of them are able to produce mycotoxins. The aims of the research were the determination of roquefortine C and PR toxin in domestic and imported blue cheeses, the identification of the penicillia used as starter, and the investigation of their capacity for producing(More)
OBJECTIVES To investigate the frequency of a first therapy interruption (TI) > or = 12 weeks, to identify the factors associated with TI and with therapy resumption, and to compare the risk of developing clinical events during TI and during continuous therapy. METHODS Observational study of 3142 patients who started a first highly active antiretroviral(More)
