L'Histoire du Sceau de Salomon ou de la coincidentia oppositorum dans les «Livres de Plomb»

Not available[es] Bajo su apariencia supuestamente cristiana, La Historia del sello de Salomón nos incita de manera muy particular a reconstruir los restos de tradiciones esotéricas musulmanas, que en otros Libros Plúmbeos se muestran de manera menos clara. La traducción francesa que ofrecemos, junto con la edición crítica del original árabe de este texto inédito, acompañadas de las versiones latinas de los traductores pontificios y de Bartolomé de Pectorano por un lado, y de la castellana de Adán Centurión por otro, constituyen una primera aportación al establecimiento definitivo de este corpus de textos. [fr] Sous ses dehors supposément chrétiens, L'Histoire du sceau de Salomon nous incite d'une manière toute particulière à y relever la trace de traditions ésotériques islamiques, qu'on observe moins nettement dans d'autres 'Livres de plomb'. La traduction en français que nous en offrons, accompagnée de l'édition critique de l'original arabe de ce texte inédit, en parallèle avec celle des versions latines des interprètes pontificaux et de Bartolomé de Pectorano, d'une part, et celle en castillan d'Adán Centurión, d'autre part, constituent une première pierre à l'établissement définitif de l'ensemble de ce corpus de textes

La circulation du savoir des Arabes chrétiens en Méditerranée médiévale. Approche des sources manuscrites

In this article we attempt a general approach to the Christian Arabic texts which were written in the Mediterranean countries or to those that reached them. We touch upon the dependence relation between manuscripts’ elaboration and copy with the transmission of knowledge through the Middle Ages.En este artículo ofrecemos una valoración general de la producción árabe cristiana originada o llegada a los países mediterráneos, incidiendo en la relación de dependencia existente entre la elaboración y la copia de manuscritos con la transmisión del saber durante la Edad Media

¿Existe una identidad mozárabe ?: Historia, lengua y cultura de los cristianos de al-Andalus (siglos IX-XII)

Ouvrage dirigé en collaboration avec Mayte Penelas (CSIC, Grenade) et Philippe Roisse (EHEH, Casa de Velazquez). Il s'agit d'un ensemble de contributions récentes (historiques et philologiques principalement) sur le thème des "Mozarabes", donc du christianisme arabisé en péninsule Ibérique entre le IXe et le XIIe siècle

Biomedical detection dogs for the identification of SARS-CoV-2 infections from axillary sweat and breath samples **

International audienceAbstract A Polymerase Chain Reaction (PCR) test of a nasal swab is still the ‘gold standard’ for detecting a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. However, PCR testing could be usefully complemented by non-invasive, fast, reliable, cheap methods for detecting infected individuals in busy areas (e.g. airports and railway stations) or remote areas. Detection of the volatile, semivolatile and non-volatile compound signature of SARS-CoV-2 infection by trained sniffer dogs might meet these requirements. Previous studies have shown that well-trained dogs can detect SARS-CoV-2 in sweat, saliva and urine samples. The objective of the present study was to assess the performance of dogs trained to detect the presence of SARS-CoV-2 in axillary-sweat-stained gauzes and on expired breath trapped in surgical masks. The samples were provided by individuals suffering from mild-to-severe coronavirus disease 2019 (COVID-19), asymptomatic individuals, and individuals vaccinated against COVID-19. Results: Seven trained dogs tested on 886 presentations of sweat samples from 241 subjects and detected SARS-CoV-2 with a diagnostic sensitivity (relative to the PCR test result) of 89.6% (95% confidence interval (CI): 86.4%–92.2%) and a specificity of 83.9% (95% CI: 80.3%–87.0%)—even when people with a low viral load were included in the analysis. When considering the 207 presentations of sweat samples from vaccinated individuals, the sensitivity and specificity were respectively 85.7% (95% CI: 68.5%–94.3%) and 86.0% (95% CI: 80.2%–90.3%). The likelihood of a false-positive result was greater in the two weeks immediately after COVID-19 vaccination. Four of the seven dogs also tested on 262 presentations of mask samples from 98 subjects; the diagnostic sensitivity was 83.1% (95% CI: 73.2%–89.9%) and the specificity was 88.6% (95% CI: 83.3%–92.4%). There was no difference (McNemar’s test P = 0.999) in the dogs’ abilities to detect the presence of SARS-CoV-2 in paired samples of sweat-stained gauzes vs surgical masks worn for only 10 min. Conclusion: Our findings confirm the promise of SARS-CoV-2 screening by detection dogs and broaden the method’s scope to vaccinated individuals and easy-to-obtain face masks, and suggest that a ‘dogs + confirmatory rapid antigen detection tests’ screening strategy might be worth investigating

Identifying SARS-COV-2 infected patients through canine olfactive detection on axillary sweat samples; study of observed sensitivities and specificities within a group of trained dogs

International audienceThere is an increasing need for rapid, reliable, non-invasive, and inexpensive mass testing methods as the global COVID-19 pandemic continues. Detection dogs could be a possible solution to identify individuals infected with SARS-CoV-2. Previous studies have shown that dogs can detect SARS-CoV-2 on sweat samples. This study aims to establish the dogs’ sensitivity (true positive rate) which measures the proportion of people with COVID-19 that are correctly identified, and specificity (true negative rate) which measures the proportion of people without COVID-19 that are correctly identified. Seven search and rescue dogs were tested using a total of 218 axillary sweat samples (62 positive and 156 negative) in olfaction cones following a randomised and double-blind protocol. Sensitivity ranged from 87% to 94%, and specificity ranged from 78% to 92%, with four dogs over 90%. These results were used to calculate the positive predictive value and negative predictive value for each dog for different infection probabilities (how likely it is for an individual to be SARS-CoV-2 positive), ranging from 10–50%. These results were compared with a reference diagnostic tool which has 95% specificity and sensitivity. Negative predictive values for six dogs ranged from ≥98% at 10% infection probability to ≥88% at 50% infection probability compared with the reference tool which ranged from 99% to 95%. Positive predictive values ranged from ≥40% at 10% infection probability to ≥80% at 50% infection probability compared with the reference tool which ranged from 68% to 95%. This study confirms previous results, suggesting that dogs could play an important role in mass-testing situations. Future challenges include optimal training methods and standardisation for large numbers of detection dogs and infrastructure supporting their deployment
