Authors: Andreis A, Imazio M, De Ferrari GM Abstract Introduction: Acute pericarditis is frequently complicated with recurrences, which represent a diagnostic and therapeutic challenge for the physician, a bothersome trouble for patients. An incorrect treatment of pericarditis may cause further recurrence of symptoms, while an incorrect diagnosis may cause either a prolonged symptoms course with a possible risk of chronic constriction, or useless and potentially harmful treatments.Areas covered: This review will focus on the most useful and recent diagnostic tools for recurrent pericarditis. Medline/Pubmed Library ...

Publication date: Available online 11 November 2019Source: Polymer TestingAuthor(s): Juan Benito Pascual-Francisco, Leonardo Israel Farfan-Cabrera, Orlando Susarrey-HuertaAbstractThis work aims to determine the tensile set behavior of a silicone rubber under different stress magnitudes and temperatures through digital image correlation implemented in an improved creep experimental set-up. Creep-recovery strains were measured with time at 20, 40 and 60 °C under tensile strengths of 98.1, 196.2 and 394.3 kPa, respectively. The behavior of creep and recovery strain with time at the different stress magnitudes and temp...

The objective of this study was to develop a qPCR method for specific enumeration of viable Listeria monocytogenes in food processing facilities and heat treated products. Primers specific for L. monocytogenes were designed to amplify a short (199 bp) or long (1561 bp) fragment of the listeriolysin (hly) gene. The short- and long-amplicon qPCR methods with and without propidium monoazide (PMA) treatment of the cells were tested for their ability to discriminate between viable (no heat) and heat-killed cells (90 °C, 10 min). The PMA-qPCR methods were subsequently used to assess the survival of L. monocytogenes durin...

Abstract We investigated combinations of gaseous essential oils (EO gases) for their synergistic inhibitory activities against Listeria monocytogenes on a laboratory medium and radish sprouts. The minimum inhibitory concentrations and minimum lethal concentrations of oregano, thyme thymol, and cinnamon bark EO gases against L. monocytogenes were 0.0781 μL/mL on nutrient agar supplemented with glucose and bromocresol purple (NGBA). A checkerboard assay showed that combinations of oregano and thyme thymol EO gases and of oregano and cinnamon bark EO gases exert the strongest synergistic antilisterial activity (...

The objective of the present work was to evaluate the effect of a process which combines mild high hydrostatic pressure - HHP (200 and 300 MPa, 5 min, 10 °C), phage Listex™ P100 and the bacteriocin pediocin PA-1 as a new non-thermal process for destruction of Listeria monocytogenes (104 CFU mL-1 or 107 CFU mL-1) in milk. For inoculum levels of 104 CFU mL-1, HHP combined with phage P100 eliminated L. monocytogenes immediately after pressurization. When L. monocytogenes was inoculated at levels of 107 CFU mL-1, a synergistic effect between phage P100, pediocin PA-1 and HHP (300 MPa) on the i...

This study aimed to elucidate the response of persistent strains of L. monocytogenes to low pH and H2O2 exposure. Almost all of the persistent strains examined were highly susceptible to low pH, whereas H2O2 susceptibility was comparable to that of control strains. Two persistent strains isolated from the same sample, however, exhibited lower susceptibility to low pH. These findings suggest an acid-susceptible phenotype predominates in the habitat, indicating that environmental conditions contribute to the establishment of persistence. Representative strains exhibiting acid-susceptible and less acid-susceptible phenotypes ...

Antibacterial effect and mechanisms of action of 460-470 nm light-emitting diode against Listeria monocytogenes and Pseudomonas fluorescens on the surface of packaged sliced cheese. Food Microbiol. 2020 Apr;86:103314 Authors: Hyun JE, Lee SY Abstract The aim of this study was to investigate the antibacterial effect of 460-470 nm light-emitting diode (LED460-470nm) illumination against pathogens and spoilage bacteria on the surface of agar media and packaged sliced cheese. LED460-470nm illumination highly inhibited the growth of Listeria monocytogenes and Pseudomonas fluorescens on agar media cover...

dez Ernesto Rivera A new class of pyrene-based dendrimers, characterized by the presence of a 1,4,7,10-Tetraazacyclododecane (cyclen) unit as the core, was studied by SSF (steady-state fluorescence) and SPC (single-photon counting fluorescence). The photophysical behavior of these dendrimers was studied in THF, DMF and DMSO solution. The typical signals for pyrene-labeled molecules were recorded in each solvent, showing the representative fluorescence spectra: the corresponding emissions of monomer and excimer of the pyrene chromophore are observed. Unexpectedly, the typical quenching of tertiary amine on the pyrene ...

AbstractA prominent notion in the literature advocates that addictive behavior emerges on the basis of the combined effect of risk and protective factors. Yet, while existing evidence supports the relevance of both riskas well as protective factors in explaining variance in addictive behavior, almost no study has ever explored the relevance of a combined index of “risk vs. protective factors” in shaping addictive behavior. Based on Albee’s (Counselling Psychology Quarterly, 8, 205 –211,1995,Journal of Primary Prevention, 27, 449 –456,2006) theorem, it was hypothesized that the ratio of risk vs...
