Objective: The operatic singing technique is frequently employed in classical music. Several acoustical parameters of this specific technique have been studied but how these parameters combine remains unclear. This study aims to further characterize the Western operatic singing technique by observing the effects of melody and technique on acoustical and musical parameters of the singing voice. Methods: Fifty professional singers performed two contrasting melodies (popular song and romantic melody) with two vocal techniques (with and without operatic singing technique). The common quality parameters (energy distribution, vibrato rate and extent), perturbation parameters (standard deviation of the fundamental frequency, signal-to-noise ratio, jitter and shimmer) and musical features (fundamental frequency of the starting note, average tempo, and sound pressure level) of the 200 sung performances were analyzed. Results: The results regarding the effect of melody and technique on the acoustical and musical parameters show that the choice of melody had a limited impact on the parameters observed, whereas a particular vocal profile appeared depending on the vocal technique employed. Conclusions: This study confirms that vocal technique affects most of the parameters examined. In addition, the observation of quality, perturbation and musical parameters contributes to a better understanding of the Western operatic singing technique. [less ▲]

A horizontal tubular fixed bed bioreactor (HFBR) and an anaerobic biodisc-like reactor (AnBDR) were designed to both fix Clostridium biomass and enable rapid transfer of the hydrogen produced to gas phase in order to decrease the strong effect of H2 partial pressure and H2 supersaturation on the performances of Clostridium strains. The highest H2 production rate (703 mL H2/L.h) and yield (302 mL/g glucose consumed i.e. 2.4 mol/mol) with the pure culture were recorded in the AnBDR with 300 mL culture medium (total volume 2.3 L) at pH 5.2 and a glucose loading rate of 2.87 g/L.h. These results are about 2.3 and 1.3-fold higher than those achieved in the same bioreactor with 500 mL liquid medium and with the same glucose consumption rate. Therefore, our experimentations and a short review of the literature reported in this paper emphasize the relevance of performing bioreactors with high L/G transfer. [less ▲]

BACKGROUND: The lymphatic system controls tissue homeostasis by draining protein-rich lymph to the vascular system. Lymphangiogenesis, the formation of lymphatic vessels, is a normal event in childhood but promotes tumor spread and metastasis during adulthood. Blocking lymphangiogenesis may therefore be of therapeutic interest. Production of adenosine is enhanced in the tumor environment and contributes to tumor progression through stimulation of angiogenesis. In this study, we determined whether adenosine affects lymphangiogenesis. METHODS: Lymphatic endothelial cells (HMVEC-dLy) were cultured in presence of adenosine and their proliferation, migration and tube formation was assessed. Gelatin sponges embedded with the stable analogue of adenosine 2-chloro adenosine were implanted in mice ear and lymphangiogenesis was quantified. Mice were intravenously injected with adenoviruses containing expression vector for 5'-endonucleotidase, which plays a major role in the formation of adenosine. RESULTS: In vitro, we observed that adenosine decreased the proliferation of lymphatic endothelial cells, their migration and tube formation. However, in vivo, gelatin sponges containing 2-chloro adenosine and implanted in mice ear displayed an elevated level of lymphangiogenesis (2.5-fold, p<0.001). Adenovirus-mediated over-expression of cytosolic 5'-nucleotidase IA stimulated lymphangiogenesis and the recruitment of macrophages in mouse liver. Proliferation of lymphatic endothelial cells was enhanced (2-fold, p<0.001) when incubated in the presence of conditioned medium from murine macrophages. CONCLUSION: We have shown that adenosine stimulates lymphangiogenesis in vivo, presumably through a macrophage-mediated mechanism. This observation suggests that blockade of adenosine receptors may help in anti-cancer therapies. [less ▲]

Study Design. Observational prospective study.Objective. Our objective was to assess the reliability and validity of the French version of the Keele STarT Back Screening Tool (SBST).Summary of Background Data. The SBST is a recently validated tool developed to identify subgroups of patients with low back pain (LBP) to guide early secondary prevention in primary care.Methods. Outpatients with LBP aged 18 years or more, attending a rehabilitation centre, a back school, a private physiotherapy unit or a fitness centre were included. Patients were assessed through the SBST, Roland-Morris Disability Questionnaire (RMDQ), Orebro Musculoskeletal Pain Screening Questionnaire (OMPSQ), Medical Outcomes Survey Short Form 36 (SF-36) questionnaire, and a pain visual analogic scale (VAS). Test-retest reliability was assessed with Kappa score or the intraclass correlation coefficient (ICC), internal consistency of the psychological subscale with the Cronbach alpha coefficient, construct validity with the Spearman's correlation coefficient, and floor and ceiling effects by percentage frequency of lowest or highest possible score achieved by respondents.Results. 108 patients with LBP were included. The test-retest reliability of the SBST total score was excellent with an ICC of 0.90 (0.81-0.95). The Cronbach alpha coefficient was 0.73 showing a good internal consistency for the psychological subscale. High Spearman's correlation coefficients of 0.74 between SBST and RMDQ, and 0.74 between the SBST and OMPSQ were observed. As expected, low to moderate correlations were observed between the SBST total score and some dissimilar measures of the SF-36. The lowest possible SBST score was observed for 8 patients (7.4%) whereas only three patients (2.8%) had the highest possible SBST score.Conclusion. The French version of the SBST is a reliable and valid questionnaire consistent with the original English version. Therefore, this new version may help French-speaking clinicians and scientists to stratify patients with LBP. [less ▲]

BACKGROUND: This study aimed to assess the interest in robot-assisted laparoscopy for deep infiltrating endometriosis and to investigate the perioperative results. METHODS: From November 2008 to April 2012, 164 women with stage 4 endometriosis who underwent robot-assisted laparoscopy (da Vinci Intuitive Surgical System) were included by to eight international participating clinical centers. This study evaluated the procedures performed, the duration of the intervention, the complications, the recurrence, and the impact on fertility. RESULTS: The average operative time was 180 min. The main complications were laparotomy (n = 1, 0.6 %), sutured bowel injury (n = 2, 1.2 %), transfusion for a 2,300-ml bleed (n = 1), prolonged urinary catheterization (n = 1, 0.6 %), ureter-bladder anastomotic leak (n = 1, 0.6 %), and ureteral fistula after ureterolysis (n = 2, 1.2 %). The reoperation rate was 1.8 % (n = 3). The mean follow-up period was 10.2 months. A full recovery was experienced by 86.7 % (98/113) of the patients. After surgery, 41.2 % (42/102) of the patients had a desire for pregnancy, and 28.2 % (11/39) of them became pregnant. CONCLUSION: This study analyzed the largest series of robot-assisted laparoscopies for deep infiltrating endometriosis published in the literature. No increase in surgical time, blood loss, or intra- or postoperative complications was observed. The interest in robot-assisted laparoscopy for deep infiltrating endometriosis seems to be promising.
