Detection and identification of Xanthomonas arboricola pv. pruni from symptomless plant material: results of an Italian test performance study
2015
Xanthomonas arboricola pv. pruni, the causal agent of bacterial spot disease of stone fruits, is a regulated quarantine pathogen in the European Union, listed as an A2 pest by the European and Mediterranean Plant Protection Organization (EPPO). Because detection and identification of this pathogen is key for its management and to ensure the production of pest free propagation material, it should be based on reliable tests, in particular when dealing with symptomless material. The current EPPO diagnostic Standard (PM 7/64) does not provide specific molecular methods for detection of this pest. The present paper summarizes the results of a test-performance study (TPS) to validate, at a nation…
Coordinated induction of drug transporters and phase I and II metabolism in human liver slices
2008
Although regulation of phase I drug metabolism in human liver is relatively well studied, the regulation of phase II enzymes and of drug transporters is incompletely characterized. Therefore, we used human liver slices to investigate the PXR, CAR and AhR-mediated induction of drug transporters and phase I and II metabolic enzymes. Precision-cut human liver slices were incubated for 5 or 24 h with prototypical inducers: phenobarbital (PB) (50 mu M) for CAR, beta-naphthoflavone (BNF) (25 mu M) for AhR, and rifampicin (RIF) (10 mu M) for PXR, and gene expression of the phase I enzymes CYP1A1, 1A2, 3A4, 3A5, 2136, 2A6, the phase II enzymes UGT1A1 and 1A6, and the transporters MRP2, MDR1, BSEP, …
Risk for non-AIDS-defining and AIDS-defining cancer of early versus delayed initiation of antiretroviral therapy
2021
BACKGROUND: Immediate initiation of antiretroviral therapy (ART) regardless of CD4 cell count reduces risk for AIDS and non-AIDS-related events in asymptomatic, HIV-positive persons and is the standard of care. However, most HIV-positive persons initiate ART when their CD4 count decreases below 500 × 10 9 cells/L. Consequences of delayed ART on risk for non-AIDS-defining and AIDS-defining cancer, one of the most common reasons for death in HIV, are unclear. OBJECTIVE: To estimate the long-term risk difference for cancer with the immediate ART strategy.DESIGN: Multinational prospective cohort study.SETTING: The D:A:D (Data collection on Adverse events of anti-HIV Drugs) study, which included…
CONSERVATIVE RESTORATION OF TWO WOODEN ARM RELIQUARIES (18TH CENTURY) FROM PALERMO’S CATHEDRAL
2016
The scientific investigations preliminary to the restoration of two golden wooden reliquaries, from Palermo's Cathedral, are reported in this work.
Scientific studies for the restauration of two wooden arm reliquaries from the Cathedral of Palermo
2017
Dedicated to Saint Generosi and Saint Rosana, the reliquary arms, recalling the shape of a body part, are today located in the Relics Chapel in Palermo Cathedral. They are probably dated to the second half of the 18th century and are attributed to an unknown artist. The aims of this study were to investigate the decorative techniques, verify the state of conservation of the constitutive materials, measure the microclimate condition in the Relics Chapel, in order to set up a correct preventive conservation strategy. In this regard, an integrated scientific investigation was performed focusing on environmental monitoring (thermo-hygrometric parameters) by HOBO system, characterization of mate…
The Association of Intraoperative driving pressure with postoperative pulmonary complications in open versus closed abdominal surgery patients – a po…
2021
Abstract Background It is uncertain whether the association of the intraoperative driving pressure (ΔP) with postoperative pulmonary complications (PPCs) depends on the surgical approach during abdominal surgery. Our primary objective was to determine and compare the association of time–weighted average ΔP (ΔPTW) with PPCs. We also tested the association of ΔPTW with intraoperative adverse events. Methods Posthoc retrospective propensity score–weighted cohort analysis of patients undergoing open or closed abdominal surgery in the ‘Local ASsessment of Ventilatory management during General Anaesthesia for Surgery’ (LAS VEGAS) study, that included patients in 146 hospitals across 29 countries.…
