Accordo e disaccordo: prospettive logico-retoriche

2012

Da ormai più di 50 anni la teoria dell’argomentazione ha acquisito un ruolo centrale nell’ambito della riflessione filosofico-linguistica. A far data dal 1958, anno in cui escono in contemporanea ma in maniera del tutto indipendente, il Trattato dell’argomentazione di Perelman ed Olbrechts-Tyteca e Gli usi dell’argomentazione di S. Toulmin si è assistito, infatti, ad una serrata rivalutazione di una logica del ragionamento che, in opposizione alla logica dimostrativa di matrice cartesiana, recupera la centralità delle nozioni di efficacia, di probabile, di uditorio. Una logica doxastica, dunque, che, per riprendere la terminologia impiegata da Aristotele, si applica a ciò che, essendo vero …

[A gastric polypoid signet ring cell carcinoma]

2007

The authors signal a case of gastric polypoid signet ring cell carcinoma, of particular interest for its rarity like show from the review of the literature, which is the first to have been described after Tabaru's citation.The study has been carried out at the Department of Surgical and Oncological Sciences of the University of Palermo. It has been based on 2000 cases analysed from June 2001 to December 2003.The authors advance some and emphasizes the diagnostic flow chart and therapeutic choices adopted.We agree that the endoscopic polypectomy is surgical procedure of first approach, but modifying the therapeutic guideline in relation to histologic examination, like happened in the case in…

Minilaparoscopy-guided spleen biopsy in systemic disease with splenomegaly of unknown origin.

2002

With the advent of a minimally invasive laparoscopy technique, the advantages of diagnostic laparoscopy are being rediscovered. We report here on four patients with systemic disease of unknown origin and splenomegaly, in whom minilaparoscopy-guided splenic biopsy yielded a definitive diagnosis. Four patients with unclear systemic disease were studied using diagnostic minilaparoscopy and guided spleen biopsy, after failure of diagnostic work-up. Minilaparoscopic spleen biopsy revealed the diagnosis of a B-cell non-Hodgkin's lymphoma in two cases. In one patient, who had a history of Still's disease, the spleen biopsy showed granulocytic infiltration in the spleen typical of an acute episode …

Preferential Biases for Texts That Include Neuroscientific Jargon

2016

The results of an experiment of preferential biases for texts that include neuroscientific jargon are presented. Such preferential bias has been reported even when the presented jargon is meaningless. In a variation of the well-known Weisberg et al. experiment, a group of undergraduate students ( N = 150; females 48%, males 52%, other 0%; M age = 22.4 year, SD = 2.6) chose between two possible explanations for a psychological phenomenon: a correct explanation or a circular restatement of facts. Unrelated neuroscientific terms were added to one of the explanations. Participants were asked to choose the correct explanation. There was a statistically significant preference for the explanation …

Influence of plasma cleaning procedure on the interaction between soft tissue and abutments: a randomized controlled histologic study

2016

Introduction Plasma application can lead to an improved adhesion between soft tissue and abutments and promotes cell spreading. Objective A triple-blinded randomized controlled clinical trial was performed to in vivo test the effect of cleaning abutment titanium surfaces with plasma of argon on cell adhesion and collagen fiber orientation at an early healing time. Material and methods Thirty healthy patients with 30 submerged implants, at the second surgery, randomly received either a specially designed abutment with no additional treatment (as they come from industry; control group, G1) or cleaned by plasma of argon (test group, G2). Two weeks thereafter, a small biopsy including abutment …

Role of the Non-Canonical RNAi Pathway in the Antifungal Resistance and Virulence of Mucorales

2021

Mucorales are the causal agents for the lethal disease known as mucormycosis. Mortality rates of mucormycosis can reach up to 90%, due to the mucoralean antifungal drug resistance and the lack of effective therapies. A concerning urgency among the medical and scientific community claims to find targets for the development of new treatments. Here, we reviewed different studies describing the role and machinery of a novel non-canonical RNAi pathway (NCRIP) only conserved in Mucorales. Its non-canonical features are the independence of Dicer and Argonaute proteins. Conversely, NCRIP relies on RNA-dependent RNA Polymerases (RdRP) and an atypical ribonuclease III (RNase III). NCRIP regulates the…

L'argomentazione come gioco linguistico. Il punto di vista aristotelico

2006

L''articolo propone una riflessione sulla teoria dell''argomentaizone in Aristotele, privilegiando un aspetto che la tradizione filosfica ha invece per lungo tempo trascurato, quello retorico. Nell''articolo si mostra che il punto di vista della "Retorica" aristotelica si rivela particolarmente vantaggioso per almeno due ordini di ragioni: in primo luogo esso consente di guardare all''argomentazione innanzitutto come ad un''attività, e più esattamente come ad un''attività naturale e spontanea tipica dell''animale linguistico (Rhet. 1354a 1-6). In secondo luogo, esso è in grado di mostrare un aspetto solitamente trascurato che ritengo invece di cruciale importanza: l''intreccio tra argomento…

Filosofia, alterità, democrazia

2021

This article intends to analyze the link existing in Apel between ethics of communication, democracy and difference. In the German author, the argumentative reason is not circumventable. The communicative and intersubjective nature of human identity founds democracy as a form of life and just coexistence. Democracy allows the individual to discover himself as tied to a common history. The paradigm of communicative philosophy overcomes both social nihilism and the dogmatism of some versions of liberalism. This rediscovery of philosophy is connected to the possibility of a social ethics and a free, equal and democratic public discourse.The problems facing today's world cannot find an adequate…

Matrix-isolation and ab initio study of the complex between formic acid and xenon

2012

Abstract We report on the identification of the complexes of formic acid (FA) and Xe in an argon matrix. The geometries, interaction energies, reaction barriers, and vibrational spectra of the FA⋯Xe complexes are calculated at the MP2 level of theory. The calculations reveal four structures for the trans-FA⋯Xe complex and four structures for the cis-FA⋯Xe complex. In the experiments, two structures of the trans-FA⋯Xe complex are observed after deposition of FA/Xe/Ar matrices, with and without OH⋯Xe interaction (H-bonded and non-H-bonded structures). The cis-FA⋯Xe complex was synthesized by vibrational excitation of the non-H-bonded trans-FA⋯Xe complex. The non-H-bonded and H-bonded structur…
