Influence of the early bacterial biofilms developed on vats made with seven wood types on PDO Vastedda della valle del Belìce cheese characteristics
2019
Early vat bacterial biofilms developed spontaneously through contact with whey have been characterized on seven wood types (Castanea sativa Miller, Cedrus libani, A. Rich., Prunus avium L., Fraxinus ornus L., Juglans regia L., Pinus nigra J.F. Arnold and Populus nigra L.). The present study aimed to evaluate the influence of these biofilms on the microbiological, chemical, physical and sensory characteristics of PDO Vastedda della valle del Belìce (VdB) cheese, processed traditionally from raw ewe's milk using wooden tools. To this purpose, the experimental cheeses after 15 d of refrigerated storage were examined. Lactic acid bacteria (LAB) populations dominated the microbial community of a…
Meta-analysis of mismatch repair polymorphisms within the cogent consortium for colorectal cancer susceptibility
2013
In the last four years, Genome-Wide Association Studies (GWAS) have identified sixteen low-penetrance polymorphisms on fourteen different loci associated with colorectal cancer (CRC). Due to the low risks conferred by known common variants, most of the 35% broad-sense heritability estimated by twin studies remains unexplained. Recently our group performed a case-control study for eight Single Nucleotide Polymorphisms (SNPs) in 4 CRC genes. The present investigation is a followup of that study. We have genotyped six SNPs that showed a positive association and carried out a meta-analysis based on eight additional studies comprising in total more than 8000 cases and 6000 controls. The estimate…
Hypoxia-inducible factor 1 alpha expression increases during colorectal carcinogenesis and tumor progression
2008
Abstract Background Hypoxia-inducible factor 1 alpha (HIF-1α) is involved in processes promoting carcinogenesis of many tumors. However, its role in the development of colorectal cancer is unknown. To investigate the significance of HIF-1α during colorectal carcinogenesis and progression we examined its expression in precursor lesions constituting the conventional and serrated pathways, as well as in non-metastatic and metastatic adenocarcinomas. Methods Immunohistochemistry and Western blot is used to analyse HIF-1α expression in normal colonic mucosa, hyperplastic polyps (HPP), sessile serrated adenomas (SSA), low-grade (TA-LGD) and high-grade (TA-HGD) traditional adenomas as well as in n…
Reduced expression of TLR4 is associated with the metastatic status of human colorectal cancer.
2007
Signaling mediating colorectal cancer (CRC) progression is incompletely understood. Previously, we identified lipopolysaccharide (LPS), an endotoxin of ubiquitously existing colonic bacteria, as a pivotal stimulus increasing the metastatic potential of human CRC. Since the ubiquitous colonic bacteria release large amounts of LPS this observation could be of enormous relevance for the progression of CRC. In this study we present data contributing to the elucidation of its mode of action. Since both receptors CD14 and TLR4 act as LPS mediators, we determined their expression in various CRC cell lines and in 115 non-metastatic, lymphogenous-metastatic and haematogenous-metastatic CRC specimens…
An experimental test of the dose-dependent effect of carotenoids and immune activation on sexual signals and antioxidant activity.
2004
Carotenoid‐based sexual traits are thought to be reliable indicators of male quality because they might be scarce and therefore might indicate the ability of males to gather high‐quality food and because they are involved in important physiological functions (as immune enhancers and antioxidants). We performed an experiment where male and female zebra finches (Taeniopygia guttata) were provided with increasing carotenoid doses in the drinking water during 4 weeks (bill color of this species is a carotenoid‐based sexual signal). Simultaneously, birds were split into two groups: one receiving weekly injections of Escherichia coli lipopolysaccharide in order to activate the immune system, the …
Poetic Industry: The Modernity of the Rhyming Weavers
2018
The so-called “Rhyming Weavers” were artisan poets, mainly writing in the 18th and 19th centuries. John Hewitt’s Rhyming Weavers & Other Country Poets of Antrim and Down (1974) has played a crucial role in defining this group of writers, both in terms of who they were – Ulster-Scots poets of a particular region in the North of Ireland – and with respect to their achievement. This paper addresses the modernity of the Weaver poets, countering a tendency to see their work as merely nostalgic or belated manifestations of pre-modernist belonging and harmony. The singular dimension given to the work of the Rhyming Weavers by the combination of the vocations of writer and weaver is scrutinized…
The Finland of Poetry Revisited Four Snapshots
2015
A poem is a condensation of signs and a method characteristic of every human being for investigating a shared reality. Accordingly, a human being also lives and exists poetically in this common world. This being so, the primacy of the mother tongue refers to the lived language, which mediates the possibility for us of carving out our own unique imprint on existence. Similarly, the native land signifies a milieu where a human being takes on a reality amidst other objects, surrounded by them and as one of them. Poetry creates harmony between past and present. peerReviewed
Philosophy of the Ancient Commentators on Aristotle
2012
From the first century BCE onwards, philosophers started to write commentaries on those Aristotle’s treatises that were meant for the internal use of his school. Plato’s works had been commented on already earlier, the first reported commentary originates in the 300s BCE. Commentaries are treatises that follow an object text in a more or less linear fashion. The format was not unknown before the first century BCE but new in extensive philosophical use. This review essay focuses on authors who commented on Aristotle’s works. The commentaries emerged when Platonists and Aristotelians observed the need to teach the philosophy of these ancient masters to their students and to systematise their …
Dots, Lines, Areas and Words: Mapping Literature and Narration (With some Remarks on Kate Chopin’s “The Awakening”)
2009
The so-called spatial turn of the humanities has led to an increasing interest in mapmaking. Looking at various trends in map-making the paper evaluates possible links and cooperation between cartography and literary studies. Differentiating between two central questions - which features of literature may be considered as spatial and in what way literature as a social practice could become spatially relevant – the paper argues that maps of literature should be based on specific features that constitute a literary text as opposed to other forms of art and discourse. Claiming that maps of literature should provide more than a visualisation of structure or an illustration of certain forms or c…
Hemodynamic changes in splanchnic circulation after orthotopic liver transplantation in patients with liver cirrhosis
2002
Background: Liver cirrhosis increases portal vein pressure and alters the splanchnic circulation. With Doppler sonography, we investigated the hemodynamic changes in the portal vein, superior mesenteric artery, hepatic and splenic arteries and spleen size in a group of patients with end-stage liver disease before and after orthotopic liver transplantation (OLT). Methods: Ten patients (seven male, three female; mean age = 48.8 ± 7.6 years) who underwent OLT for liver cirrhosis mainly associated with hepatitis C virus infection completed the study. The control group consisted of 10 patients matched by sex and age who had no gastroenterologic or vascular diseases. All patients underwent duplex…
