Substrat i superstrat en l'evolució del català
1999
Reflections on the significance of substratum and superstratum in the genesis and evolution of Catalan. The author considers how the recourse to the pre-Roman susbtratum in the etymological interpretation or in the historical and critical grammar has been carried to excess both by those absolutely against it and by those who take it as an all-explaining panacea. He also points out that, conversely to the interest in substratum, the Germanic superstratum has not received the attention it deserves in the genesis of Catalan because of various prejudices, some of them of an ideological kind.
La dixi de persona en el discurs acadèmic oral en català
2008
In this article the results of a quantitative and qualitative research into person deixis are shown and, generally, the ones related to the participative inscription, within the oral academic genre of the master class. In order to do so, this discursive genre has been contrasted with colloquial oral conversation and academic prose. The quantitative results include the distribution of the references to the enunciator and to the enunciatary in the three genres (the individual ones, the collective ones and those that allow the participants to avoid direct reference). From the qualitative point of view, the main pragmatic functions that make the deictic expressions of person in the master class…
Abstract 4219: Lysosomal membrane permeabilization, a novel anticancer mechanism induced by pterostilbene
2011
Abstract Pterostilbene (Pter) (3,5-dimethoxy-4′-hydroxystilbene), a natural dimethylated analog of resveratrol, is a phytoalexin abundant in plants and fruits with a number of potential benefits for human health. Darakchasava, an Indian herbal preparation of Vitis Vinifera, contains Pter and is prescribed as a cardiotonic in ayurvedic and traditional medicine. Furthermore, some observations indicate that Pter can be beneficial in the prevention and treatment of different diseases such as diabetes, dyslipidemia, or cancer. Pter shows higher bioavailability than resveratrol. The substitution of two OH groups (positions 3 and 5) by methyl groups increases the stabilityof the molecule and its r…
Umbilical venous catheters placement evaluation on frontal radiogram: application of a simplified flow-chart for radiology residents
2017
Background: Umbilical Venous Catheter (UVC) are commonly used in neonatal period; they can be not correctly positioned and could be associated with complications. The purpose of this article is to suggest a flow-chart to evaluate the placement of UVC, testing it in young radiologists-in-training. Method: We developed a simple flow-chart to asses, steps by step, UVC placement considering its course and tip location (ideally placed in the atriocaval junction). We tested the flow-chart impact asking to 20 residents to evaluate the placement of 10 UVC before and after they familiarized with the flow-chart and the anatomical findings of a newborn. The agreement among the 20 students was evaluate…
Analyse et détection des électrogrammes complexes fractionnés en vue de soigner la fibrillation auriculaire à l'aide de techniques d'ablation par rad…
2013
This manuscript presents research on the analysis and the detection of Complex Fractionated Atrial Electrograms (CFAE). In the first part, following a presentation over Atrial Fibrillation (AF) mechanisms and bioelectrical signals, the most commonly used tools for analyzing CFAE are presented. Linear tools are initially applied to signals from AF ablation procedures, then nonlinear tools are shown and integrated intoa CFAE detection algorithm. This one is based on the quantification of electrogram recurrence properties. In the second part, the cell and cardiac muscle tissue are described and simulated using mathematical models. Models such as FitzHugh Nagumo, Aliev Panfilov and Courtemanche…

THE SEMANTIC NETWORK OF THE LATIN PREPOSITION PER: A DIACHRONIC INVESTIGATION
2020
Proponiamo qui i risultati di uno studio corpus-based sugli slittamenti diacronici osservabili nel network semantico della preposizione per in latino. Sulla base della Cognitive Grammar, descriviamo la semantica di per situandola lungo un continuum che procede dal concreto all’astratto, a partire da un contenuto schematico originario; discutiamo, quindi, i percorsi attraverso i quali i nuovi significati astratti emergono attraverso sli ttamenti metonimici, focalizzando la nostra attenzione sui ruoli causali e sulla caratteristica di animatezza.
Fluorescent probes to evaluate the physiological state and activity of microbial biocatalysts: A guide for prokaryotic and eukaryotic investigation
2008
International audience; Many fluorescent techniques are employed to evaluate the viability and activity of microbial cells used in biotechnology. These techniques are sometimes complex and the interpretation of results opened to misunderstanding. Moreover, new developments are constantly proposed especially concerning a more accurate evaluation of the state of the cells including eukaryotic microorganisms. This paper aims at presenting to biotechnologists unfamiliar with fluorescence the principles of these methods and the related possible pitfalls. It focuses on probes of the physical (integrity and fluidity) and energetical (intracellular pH and membrane potential) state of the cell membr…
Essential oils of Salvia bracteata and Salvia rubifolia from Lebanon: Chemical composition, antimicrobial activity and inhibitory effect on human mel…
2009
Aim of the study: Salvia bracteata Banks et Sol. and Salvia rubifolia Boiss. are known in folk medicine of Lebanon for the treatment of microbial infections, cancer, urinary and pulmonary problems. In the present study the chemical composition and antimicrobial activity of essential oils from aerial parts of Salvia bracteata and Salvia rubifolia collected in Lebanon were evaluated. The oils were also tested for their potential antiproliferative effects against M14 human melanoma cells. Material and methods: The oils were studied by GC and GC-MS and their antibacterial activity (MIC and MBC) was tested against ten bacteria species using the broth dilution method. The inhibitory effect on hum…
