“Man as Literature. Recurring Memories”

2020

Abstract In the reading cultural openness, the human effort is the key to a de-construction that opens the source of knowledge. Can we only build libraries? Do we only read the book or also the author? The line of the book’s culture runs parallel to daily life or breaks the rhythm or tense knowledge. How do we build man-literature? Is knowledge an Oath in Gandhi’s meaning, a Covenant with a memory? And how does the dimension of human dignity evolve from reading into knowledge? We have no answer. However, we have a description of the interrogation process.

“The archetype of the pathetic man, between objectivation and objectification”

2020

Abstract The study follows the archetype - prototype - stereotype path in the evolution of the plastic model, in order to capture the organic connection between these notions specific to iconic language. The chronology is reversed to capture a contemporary stereotype of advertising images, as a result of an apparent form of expression of female emancipation: the erotic objectification of man. Far from being just „trendy”, the visual motif has a whole history that deserves to be pointed out as the different approaches always reflect the spirit of that era.

The Bread of God: religious and symbolic aspects of bakery

2019

Abstract The present conference discusses the symbolic meaning of bread in the religious mentality of the Ancient Near East. We will find that bread, besides being a food necessary for its existence, also represented a cultural archetype that summed up and assumed in itself either different divinities of Oriental civilizations, or had a ritual-sacrificial character, in order to facilitate man rather immortality.

Fluidizing the Membrane by a Local Anesthetic: Phenylethanol Affects Membrane Protein Oligomerization

2010

The exact mechanism of action of anesthetics is still an open question. While some observations suggest specific anesthetic-protein interactions, nonspecific perturbation of the lipid bilayer has also been suggested. Perturbations of bilayer properties could subsequently affect the structure and function of membrane proteins. Addition of the local anesthetic phenylethanol (PEtOH) to model membranes and intact Escherichia coli cells not only affected membrane fluidity but also severely altered the defined helix-helix interaction within the membrane. This experimental observation suggests that certain anesthetics modulate membrane physical properties and thereby indirectly affect transmembran…

Tra metaforizzazione e simbolizzazione: la metafora come dispositivo linguistico di visualizzazione?

2023

In this paper we will consider metaphor as a phenomenon that lies at the interface between language and imagination. By focusing on how this phenomenon works, we will attempt to shed light on how symbols work. After analyzing the relationship between metaphor and sym bol to highlight the main similarities and differences, we will examine the functions of metaphor with particular reference to the thought of Paul Ricœur. In particular, we will highlight the role that the French thinker attributes to the imagination in constructing the meaning of a metaphor. Finally, after highlighting the relationship between images and words, between the linguistic dimension and the dimension of aisthesis in…

On the aestheticization of technologized bodies : a portrait of a cyborg(ed) form of agency

2017

Discussions revolving around cyborgs seldom include aesthetics, let alone propose aesthetics as an inextricable part of the phenomenon of the cyborg. Rather, the term “cyborg”, a contraction of “cybernetic organism”, evokes a figure of the (hu)man- machine. In the field of social and political sciences, the cyborg is designated a human-machine hybrid, a metaphor of humans becoming machinelike, or a portrait of (political) agency in an era of high technology. These approaches promote a figure of technologized bodies, that is, the cyborg as a figure of technologically dominated and altered bodies. I will sustain that the cyborg contributes to our understanding of agency in the age of high tec…

Speaking from above and below -The Gospel of John as metaphorical and narrative reference to a distant reality

2018

The one who is from the earth belongs to the earth and speaks from the earth (Jn 3:31). How can one speak from the earth and at the same time about heavenly things? The Fourth Gospel (FG) creates a tension between these two realms of perception and cognition. To reach beyond or above the earth we have to transcend time and space, our individual context and limited visual horizon. To overcome the obstacle of confined space we can rely on metaphors since their key faculty is to transport (μετα-φέρω). To transcend the limitations of time we can recruit the genre of narration. These two modes of references to a reality that is located and dated beyond our realms are at work in the FG. With Rico…

Sevoflurane Impairs Cerebral Blood Flow Autoregulation in Rats: Reversal by Nonselective Nitric Oxide Synthase Inhibition

2005

UNLABELLED In this study, we investigated the effects of 1.0 and 2.0 minimum alveolar anesthetic concentration (MAC) sevoflurane on cerebral blood flow (CBF) autoregulation before and after nonselective inhibition of nitric oxide (NO) synthase in rats. Rats were randomly assigned as follows: Group 1 (n = 8): 1.0 MAC sevoflurane; Groups 2 and 3 (n = 8 per group): 2.0 MAC sevoflurane. Assessment of autoregulation within a mean arterial blood pressure range of 140-60 mm Hg was performed by graded hemorrhage before and after administration of l-arginine methyl ester (l-NAME, 30 mg/kg IV, Groups 1 and 2) or during hypocapnia (Group 3). In 10 additional animals, brain tissue NO(2)(-) concentratio…

Sevoflurane-induced reduction of bispectral index does not affect human cerebral microcirculation

Inhalational or intravenous anesthetics for craniotomies? Pro inhalational.

2006

In neurosurgery, anesthesiologists and surgeons focus on the same target - the brain. The nature of anesthetics is to interact with brain physiology, leading to favorable and adverse effects. Research in neuroanesthesia over the last three decades has been dedicated to identifying the optimal anesthetic agent to maintain coupling between cerebral blood flow and metabolism, keep cerebrovascular autoregulation intact, and not increase cerebral blood volume and intracranial pressure.Sevoflurane is less vasoactive than halothane, enflurane, isoflurane, or desflurane. The context sensitive half-life is short and similar to that of desflurane, which translates into fast on and offset. Compared wi…
