Intestinal anti-inflammatory activity of ellagic acid in the acute and chronic dextrane sulfate sodium models of mice colitis.

2013

Abstract Ethnopharmacological relevance Pomegranate (Punica granatum L.; Lythraceae) has traditionally been used for the treatment of various inflammatory diseases, including ulcerative colitis (UC). Because its fruits and extracts are rich in ellagitannins, which release ellagic acid when hydrolyzed, consumption of pomegranate products is currently being widely promoted for their potential health effects, including the prevention of inflammatory diseases and cancer. To evaluate the anti-inflammatory effects of ellagic acid on dextran sulfate sodium (DSS)-induced acute and chronic experimental colitis in two different strains of mice and to elucidate its possible mechanisms of action. Mater…

Induction of tolerogenic lung CD4+ T cells by local treatment with a pSTAT-3 and pSTAT-5 inhibitor ameliorated experimental allergic asthma.

2010

Signal transducer and activator of transcription (STAT)-3 inhibitors play an important role in regulating immune responses. Galiellalactone (GL) is a fungal secondary metabolite known to interfere with the binding of phosphorylated signal transducer and activator of transcription (pSTAT)-3 as well of pSTAT-6 dimers to their target DNA in vitro. Intra nasal delivery of 50 μg GL into the lung of naive Balb/c mice induced FoxP3 expression locally and IL-10 production and IL-12p40 in RNA expression in the airways in vivo. In a murine model of allergic asthma, GL significantly suppressed the cardinal features of asthma, such as airway hyperresponsiveness, eosinophilia and mucus production, after…

Does Probiotic Yeast Act as Antigenotoxin?

2005

The effect of probiotic yeast Saccharomyces boulardii on genotoxicity induced by the well-known mutagen 4-nitroquinoline-N-oxide (4-NQO), as well as antibacterial (furazolidone) and antibiotic (nalidixic acid) drugs, has been studied using the short-term bacterial assay, SOS chromotest, with Escherichia coli PQ 37 as the test organism. It has been shown that S. boulardii possesses antigenotoxic activity, revealed by SOS chromotest, when coincubated with these genotoxins. A weaker antigenotoxic activity against the same compounds was observed with S. carlsbergensis, too.

The MAPK Hog1 recruits Rpd3 histone deacetylase to activate osmoresponsive genes

2003

Regulation of gene expression by mitogen-activated protein kinases (MAPKs) is essential for proper cell adaptation to extracellular stimuli. Exposure of yeast cells to high osmolarity results in rapid activation of the MAPK Hog1, which coordinates the transcriptional programme required for cell survival on osmostress. The mechanisms by which Hog1 and MAPKs in general regulate gene expression are not completely understood, although Hog1 can modify some transcription factors. Here we propose that Hog1 induces gene expression by a mechanism that involves recruiting a specific histone deacetylase complex to the promoters of genes regulated by osmostress. Cells lacking the Rpd3-Sin3 histone deac…

In vivo Antimicrobial Activity Assessment of a Cauliflower By-Product Extract Against Salmonella Typhimurium

2020

The main objective of this work was to study the antimicrobial effect of a cauliflower by-product infusion into an affordable in vivo model (Caenorhabditis elegans). The infusion demonstrated some protective effect on non-infected and infected worms with Salmonella Typhimurium as indicated by higher survival percentile values (75, 50, 25, and 5% percentiles) as compared with those from worms unexposed to the infusion. The antimicrobial effect of the infusion was evaluated on Salmonella intestinal colonization of infected worms (24, 48, and 96 h post-infection). At 96 h post-infection, the concentration of Salmonella was reduced around 2 log cycles in infected cauliflower treated group (p < …

Effect of muscle type and animal category on fatty acid composition of bresaola made from meat of Cinisara cattle: preliminary investigation

2020

The bresaola could represent an alternative commercial opportunity for autochthonous dairy cattle farms. Therefore, a study was carried out to investigate the fatty acid (FA) composition of bresaola made using Semimembranosus (SMm), Semitendinosus (STm), and Biceps brachii (BBm) muscles from grazing young bulls (GB), housed young bulls (HB) or grazing adult cows (AC) of Cinisara breed. Animal category, fat content, feeding system, and type of muscle influenced the FA composition of bresaola. Fatter products, made from AC and HB meat, or with STm and BBm muscles showed lower polyunsaturated/saturated FA ratio. The bresaola from young bulls fed pasture-based diet showed an increased polyunsat…

Opuntia cladodes as functional ingredient in durum wheat bread: rheological, sensory, and chemical characterization

2021

Cladodes are considered by-products of Opuntia ficus-indica cultivation. Their addition as source of antioxidants to durum wheat breads could have effects on preventing cardiovascular diseases, cancers, and inflammation. The inclusion of 0-5-10-15% cladodes, harvested in three different locations, on quality and antioxidant properties of fortified durum wheat breads has been evaluated. The enrichment with 10% of cladodes resulted in an increase in the content of total phenolics (14.8 vs 2.7 mg GAE/100 g of control bread), a decrease of IC50 (3.28 vs 49.7 mg/ml of control bread), good rheological characteristics of loaves and largely positive evaluation by panel test. Fortification with 15% …

Suicidio e autocensura nelle traduzioni italiane dei Frauenromane

2015

Fra i numerosi romanzi tedeschi che si imposero sulla scena editoriale dell’Italia degli anni Venti e Trenta, i Frauenromane, romanzi scritti da donne e rivolti a donne, veicolavano il modello della Neue Frau weimariana, donna lavoratrice, economicamente indipendente e sessualmente emancipata. La circolazione di alcuni di questi volumi fu ostacolata dal regime fascista che, impensierito dal potenziale anticonformista di questi testi, era attento ad assegnare ben altri ruoli alle donne italiane, isolando ogni minaccia di sovversività.Uno dei temi più scomodi – aborto, emancipazione femminile – era il suicidio, ritenuto tanto immorale quanto pericoloso per il suo rischio emulativo. Tramite un…

DELEZIONE CROMOSOMICA CRIPTICA 1p31.1: EFFICACIA DELLA TERAPIA COMBINATA CON L-TIROXINA, GH ED LHRHa PER MIGLIORARE LA PROGNOSI STATURALE

2019

Le anomalie cromosomiche criptiche, non evidenziabili con la citogenetica tradizionale sono associate a un quadro clinico suggestivo di anomalia, pur in presenza di cariotipo normale, che richiede tecniche diagnostiche come l’ibridazione in situ. Descriviamo il caso di una ragazza che ha raggiunto la statura definitiva, con quadro polimalformativo già alla nascita e riscontro di cariotipo 46, XX con inversione pericentrica di un cromosoma 1. L’ indagine FISH del cromosoma 1 mette in evidenza i seguenti punti di rottura: 1p32 e 1q25. Si pone diagnosi di sindrome da delezione cromosomica criptica (del 1p31.1). Si tratta di una sindrome polimalformativa caratterizzata da ritardo dello sviluppo…
