Israël : chants judéo-espagnols de la Méditerranée orientale

L’anthologie Chants judéo-espagnols de la Méditerranée orientale comprend vingt-cinq chants monodiques appartenant à cinq genres représentatifs de cette tradition. Ils sont interprétés à tour de rôle en solo et sans aucun accompagnement, par deux chanteuses vivant en Israël : Bienvenida « Berta » Aguado, originaire de Turquie, et Loretta « Dora » Gerassi, de Bulgarie. Le choix de restreindre l’anthologie à une région stylistique définie du riche patrimoine vocal judéo-espagnol qui survit dans..

Inhibition of Streptococcus gordonii Metabolic Activity in Biofilm by Cranberry Juice High-Molecular-Weight Component

Previous studies demonstrated that a cranberry high-molecular-mass, nondialyzable material (NDM) can inhibit adhesion of numerous species of bacteria and prevents bacterial coaggregation of bacterial pairs. Bacterial coaggregation leads to plaque formation leading to biofilm development on surfaces of oral cavity. In the present study, we evaluated the effect of low concentrations of NDM on Streptococcus gordonii metabolic activity and biofilm formation on restorative dental surfaces. We found that the NDM selectively inhibited metabolic activity of S. gordonii, without affecting bacterial viability. Inhibiting the metabolic activity of bacteria in biofilm may benefit the health of the oral cavity

Notions d’esthétique dans les traités arabes sur la musique

Dans son aperçu de « La musique de l’Islam (The New Oxford Hitory, vol. I, p. 433), Henry George Farmer dit: « La conception islamique ignorait l’esthétique en tant que science du beau. La raison principale était que l’Orient [....] avait une confiance inébranlable en le ta’thīr (influence) dans la musique, un dogme que les Grecs appelaient l’éthos ». La doctrine de l’éthos exclue-t-elle réellement l’esthétique, la science du beau, ou plutôt le contredit-elle? En 1750, le Français Charles Fonton, en écrivant sur la musique turque, accusa ses contemporains de se laisser guider par l’amour-propre, par ce que nous appellerions aujourd’hui l’ethnocentrisme; il conclut: « La musique orientale possède sa beauté propre et ses propres critères pour l’évaluer ». Tout en essayant de tirer au clair l’approche de Farmer, on s’inspirera des écrits théoriques arabes afin d’évaluer l’approche de Fonton.In his survey article « The Music of Islam » (The New Oxford History, vol. I, p. 433), H.G. Farmer states: « Aesthetics, the science of the beautiful, did not exist in Islamic conceptions. The chief reason for this was that the Orient [...] put great trust in the doctrine of the ta’thīr (influence) in music, a dogma called by the Greeks the ethos ». Does the doctrine of ethos really exclude aesthetics, the science of the beautiful, or is it in contradiction with it? In 1750, the Frenchman Charles Fonton, who wrote on Turkish music, accused his contemporaries of permitting themselves to be guided by self-love, which we would now call ethnocentrism, concluding: « Oriental music has its own beauty and its own criteria for judging that beauty ». While attempting to clarify Farmer’s approach, evidence from the Arab theoretical writings will be provided to assess Fonton’s approach

Early Detection of COVID-19 in Female Athletes Using Wearable Technology

Background: Heart rate variability (HRV), respiratory rate (RR), and resting heart rate (RHR) are common variables measured by wrist-worn activity trackers to monitor health, fitness, and recovery in athletes. Variations in RR are observed in lower-respiratory infections, and preliminary data suggest changes in HRV and RR are linked to early detection of COVID-19 infection in nonathletes. Hypothesis: Wearable technology measuring HRV, RR, RHR, and recovery will be successful for early detection of COVID-19 in NCAA Division I female athletes. Study Design: Cohort study. Level of Evidence: Level 2. Methods: Female athletes wore WHOOP, Inc. bands through the 2020 to 2021 competitive season. Of the athletes who tested positive for COVID (n = 33), 14 had enough data to be assessed (N = 14; 20.0 ± 1.3 years; 69.8 ± 7.2 kg; 172.0 ± 8.3 cm). Roughly 2 weeks of noninfected days were used to set baseline levels of HRV, RR, recovery, and RHR to compare with -3, -2, and -1 days before a positive COVID-19 result. Results: Increases in RR (P = 0.02) were detected on day -3. RHR (P \u3c 0.01) and RR increased (P \u3c 0.01), while HRV decreased (P \u3c 0.05) on day -1, compared with baseline. Differences were noted in all variables on the day of the positive COVID-19 result: decreased HRV (P \u3c 0.05) and recovery scores (P \u3c 0.01), and increased RHR (P \u3c 0.01) and RR (P \u3c 0.01). Conclusion: In female athletes, wearable technology was successful in predicting COVID-19 infection through changes in RR 3 days before a positive test, and also HRV and RHR the day before a positive test. Clinical Relevance: Wearable technology may be used, as part of a multifaceted approach, for the early detection of COVID-19 in elite athletes through monitoring of HRV, RR, and RHR for overall team health

An Enhanced Approach for Segmentation of Liver from Computed Tomography Images

287-293An accurate segmentation of liver from Computed Tomography (CT) scans is essential for liver tumor research as it offers valuable information for clinical diagnosis and treatment. However, it is challenging to achieve an accurate segmentation of the liver because of the blurred edges, low contrast and similar intensity of the organs in the CT scan. In this paper, an automated model which will segment the liver from CT images using a hybrid algorithm has been used. The segmentation of liver from CT scan is done with the help of Particle Swarm Optimization (PSO) followed by level set algorithm. The ultimate aim of using this hybrid algorithm is to improve the accuracy of liver segmentation. Computer aided classification of liver CT into healthy and tumorous images aids in diagnosis of liver diseases. It can help a great deal in diagnosis of liver disorders. In order to achieve better classification results, it is of high importance to segment the liver accurately without an error of over or under segmentation. The results obtained indicate that the approach used in this work is faster and has 98.62% accuracy, 99.2% specificity, 97.1% sensitivity, 97.8% F-measure, 96.6% Matthews Coefficient Constant (MCC), 99.08% precision, 97.8% dice coefficient and 95.7% jaccard coefficient in segmenting the liver

Tannerella forsythia, a periodontal pathogen entering the genomic era

Several questions need to be addressed to evaluate whether Tannerella forsythia is to be considered a periodontal pathogen. T. forsythia has been detected in periodontal health and disease, so could it be a pathogen? The species was not detected in many studies despite finding other putative pathogens, so could it be important in pathogenicity? The challenges of working with T. forsythia include its fastidious and anaerobic growth requirements for cultural detection. Thus, studies associating T. forsythia with periodontal and other oral infections have used noncultural approaches (immunoassays and DNA-based assays) in addition to cultural approaches. We feel the timing of this review represents an interesting transition period in our understanding of the relationships of species with infection. Information from the recently released full genome sequence data of T. forsythia will provide new approaches and tools that can be directed to assess pathogenicity. Furthermore, molecular assessment of gene expression will provide a new understanding of the pathogenical potential of the species, and its effect on the host. T. forsythia, was described in reviews focusing on periodontal pathogens associated with herpesvirus detection (200), species for which genome projects were underway (41), members of polybacterial periodontal pathogenic consortium (91), and participants in periodontal microbial ecology (202). We will describe the history, taxonomy, and characteristics of T. forsythia, and related species or phylotypes in the genus Tannerella. To assess the pathogenic potential of T. forsythia, we first describe species associations with periodontal and other infections, including animal models, as has been the traditional approach arising from Koch’s postulates (203). Criteria for pathogenicity were expanded to incorporate sequence- derived information (58), and again more recently to include molecular signatures of pathogens and disease (170). We used sequence and genome-derived information, in addition to biofilm, pathogenic mediators, and host responses, to further explore the pathogenic potential of T. forsythia
