Journal ArticleDOI
Metagenomics Reveals Dysbiosis and a Potentially Pathogenic N. flavescens Strain in Duodenum of Adult Celiac Patients
Valeria D'Argenio,Giorgio Casaburi,Vincenza Precone,Chiara Pagliuca,Roberta Colicchio,Daniela Sarnataro,Valentina Discepolo,Sangman M. Kim,Ilaria Russo,Giovanna Del Vecchio Blanco,David S. Horner,Matteo Chiara,Graziano Pesole,Graziano Pesole,Paola Salvatore,Giovanni Monteleone,Carolina Ciacci,Gregory J Caporaso,Bana Jabri,Francesco Salvatore,Lucia Sacchetti +20 more
TL;DR: Marked dysbiosis and an abundance of a peculiar CD-Nf strain characterize the duodenal microbiome in active CD patients thus suggesting that the CD-associated microbiota could contribute to the many inflammatory signals in this disorder.
Journal ArticleDOI
Inhibitory effect of pomegranate (Punica granatum L.) polyphenol extracts on the bacterial growth and survival of clinical isolates of pathogenic Staphylococcus aureus and Escherichia coli
Caterina Pagliarulo,Valentina De Vito,Gianluca Picariello,Roberta Colicchio,Gabiria Pastore,Paola Salvatore,Maria Grazia Volpe +6 more
TL;DR: Data herein indicated that both pomegranate aril and peel extracts have an effective antimicrobial activity, as evidenced by the inhibitory effect on the bacterial growth of two important human pathogens, including Staphylococcus aureus and Escherichia coli, which are often involved in foodborne illness.
Journal ArticleDOI
Regulation and differential expression of gdhA encoding NADP-specific glutamate dehydrogenase in neisseria meningitidis clinical isolates
Caterina Pagliarulo,Paola Salvatore,Lucia Rosaria De Vitis,Roberta Colicchio,Caterina Monaco,Maurizio Tredici,Adelfia Talà,Marcellino Bardaro,Alfredo Lavitola,Carmelo B. Bruni,Pietro Alifano +10 more
TL;DR: DNA–protein interaction studies demonstrated that 2‐oxoglutarate, a product of the catabolic reaction of the NADP‐GDH and an intermediate of the tricarboxylic acid (TCA) cycle, inhibits binding of GdhR to gdhA P2.
Journal ArticleDOI
In vitro antibacterial activity of Pomegranate juice and peel extracts on cariogenic bacteria
Gianmaria Fabrizio Ferrazzano,Elisa Scioscia,Daniela Sateriale,Gabiria Pastore,Roberta Colicchio,Chiara Pagliuca,T Cantile,B Alcidi,M Coda,A Ingenito,Elena Scaglione,Annunziata Gaetana Cicatiello,Maria Grazia Volpe,Michele Di Stasio,Paola Salvatore,Caterina Pagliarulo +15 more
TL;DR: In vitro microbiological tests demonstrate that the hydroalcoholic extracts of pomegranate juice and peel are able to contrast the main cariogenic bacteria involved in tooth decay.
Journal ArticleDOI
Impairment of circulating endothelial progenitors in Down syndrome

TL;DR: It is demonstrated that infected progenitors with trisomy 21 have a more pronounced perturbation of immune response genes than infected euploid cells, and that their progenitor cells are more susceptible to hydroperoxide-induced oxidative stress and infection with Bartonella henselae.
