Rôle de la banque de graines du sol dans la régénération des forêts denses humides d’Afrique centrale
Authors: DOUH Chauvelin 
Published: November 2019

La présente thèse s’intéresse aux moteurs de la régénération des forêts denses humides tropicales d’Afrique, plus particulièrement au rôle joué par la banque de graines du sol dans cette régénération. Plus spécifiquement, l’étude vise à : évaluer l’abondance et la composition floristique de la banque de graines du sol de deux types de forêt reposant sur des sols différents ; quantifier l’abondance de la banque de graines du sol d’une essence commerciale importante, le tali (Erythrophleum suaveolens) et étudier les facteurs intervenant dans la levée de dormance de ses graines ; évaluer la capacité du système d’imagerie hyperspectrale proche infrarouge à discriminer des graines de deux espèces sœurs, E. suaveolens et E. ivorense. Les résultats montrent que la densité et la composition floristique de la banque de graines du sol varient significativement selon les types de forêt et de sol. Les taxons pionniers sont largement majoritaires dans les deux cas, mais sont mieux représentés dans la banque du sol de la forêt à Celtis (vieille forêt secondaire) que dans le sol de la forêt à Manilkara (forêt mature). Tous taxons confondus, la similarité floristique entre la banque de graines du sol et la végétation environnante est relativement faible quel que soit le type forestier. Cependant, cette similarité s’avère nettement plus importante en ne considérant que les taxons pionniers. Seulement trois espèces de bois d’œuvre ont été observées dans la banque du sol : Nauclea diderrichii, Staudtia kamerunensis et Erythrophleum suaveolens. E. suaveolens, le tali, est une des espèces les plus exploitées d’Afrique centrale. L’évaluation de l’abondance des graines de l’espèce au sein des deux types de forêt révèle une densité plus élevée en forêt à Celtis qu’en forêt à Manilkara, où les graines sont quasi inexistantes bien que les densités d’arbres en âge de reproduction ainsi que les structures diamétriques, soient similaires entre sites. Différentes hypothèses ont été émises pour expliquer ce résultat, la plus probable étant liée à la structure de végétation différente entre les sites. Les canopées des individus vivant dans la forêt à Manilkara seraient davantage dominées et fructifieraient moins fréquemment que dans la forêt à Celtis. La longévité des graines étudiées par spectroscopie de masse par accélérateur révèle que ces semences de tali, viables et enfouies dans le sol, seraient âgées d’environ dix ans. Le système d’imagerie hyperspectrale proche infrarouge s’est avéré efficace dans la distinction des graines d’E. suaveolens et E. ivorense, ce qui ouvre d’intéressantes perspectives quant à l’utilisation de cette technique pour étudier la banque de graines du sol.

Aim: The aim of this study was to evaluate knowledge and attitudes regarding potentially malignant oral lesions and oral cancer among undergraduate dental students with or without training in the oral medicine. Methods: A cross-sectional study was undertaken to assess all undergraduate dental student (1st to 5th year) in two private universities in the state of Paraná, Brazil. A structured questionnaire about knowledge regarding potentially malignant oral lesions, continuing education, and different approaches to diagnosis was administered to dental students with or without training in the oral medicine discipline between May and July 2015. Descriptive statistics were obtained, and the data were analyzed using a chi-square test to compare knowledge in dental students. Results: A total of 662 undergraduate dental students were invited to participate, and the response rate was 97.6% (n = 646). Of the responders, 472 were female (73.1%), 168 were male (26.0%), and 6 did not declare what sex they were (0.9%). Undergraduate dental students who had previously studied oral medicine tended to report that they always perform complete intraoral examination (76.3%) and identified alcohol (87%) and tobacco consumption (97%) and sun exposure (80%) as major risk factors for developing oral cancer. While students who had not yet studied oral medicine poorly identified these factors. Students who had previously studied the discipline did not identify cheilitis actinica (26%) and erythroplakia (32%) as potentially malignant lesions. Only, 32.6% of dental students participate in continuing education during the past year. Conclusions: Dental students trained in the oral medicine discipline exhibited satisfactory knowledge necessary for the prevention and early identification of potentially malignant oral lesions and oral cancer. Continuing education during undergraduate and after academic training is very important.

Aim: to evaluate the synergic impact of muscular TMD and malocclusion on quality of life, masticatory capacity and emotional features of young adults. Methods: this cross-sectional study comprised 4 groups (n= 15): G1, individuals without TMD or malocclusion; G2, with TMD and malocclusion; G3, with TMD and without malocclusion, and G4, without TMD and with malocclusion. Muscular TMD was diagnosed by RCD/TMD. Data included quality of life (OHIP-14), masticatory capacity test (X50), emotional stress (PSS-14), depression (MDI), pain intensity and salivary cortisol. Comparative statistical analysis included One-way ANOVA and Tukey post hoc test (X50, stress and cortisol) and GENMOD followed by Wald test (OHIP-14 and pain data). Fisher's and Pearson's association analysis were carried out. Results: Comorbidity of muscular TMD and malocclusion leads to significant lower masticatory capacity (p<0.05). TMD groups independently of the occlusal condition had considerably lower OHIP-14 scores and higher stress levels (self-perceived and hormonal) (p<0.05). There was no statistically significant difference of emotional depression among groups. A significant positive correlation was observed among quality of life, stress and pain perception. Conclusion: muscular TMD in the overlap of malocclusion potentializes their negative effect on masticatory capacity. In addition, the hindering effect of the comorbidity is variable, however, TMD has a greater negative impact on quality of life and stress, whilst malocclusion on mastication.

Implementation of a New Methodology for Efficient Well Abandonment Operations
Authors: Shine Joe 
Published: November 2019

AbstractPlugging and abandonment operations may require multiple cement plugs to isolate a given wellbore from the surface or seabed. The rig operational time placing and then validating the integrity of selective cement plugs could range from a couple of days to one week depending on the quantity and location of the plugs in the wellbore. As most plugs lengths target 500 feet, wellbore abandonment operations can become inefficient depending on the abandonment requirements. A new methodology for cement plug installation, during wellbore abandonment operations, using a drilling rig improves efficiency by reducing the quantity of cement plugs deployed while obtaining better placement success.The methodology, a "pump and pull" technique, has enabled successful plug placements range from a 1,650-foot plug set in a highly deviated well to a 1,950-foot plug set in a vertical well. Most of these placements enabled a reduction in the plugs required to achieve the abandonment objectives. The manuscript discusses the general operational procedures, laboratory testing, and design methods to manage the deployment scope using drilling rigs without coiled tubing assistance.

Published: November 2019

Abstract
Background Monocytes are a major component of the tumor microenvironment (TME) in pancreatic ductal adenocarcinoma (PDAC). However, the complex interactions between tumor cells and monocytes and their role in tumor invasion have not been fully established.
Methods To specifically test the impact of interaction on invasive potential two PDAC cell lines PaTu8902 and CFPAC-1 were selected on their ability to form invasive adhesions, otherwise known as invadopodia and invade in a spheroid invasion assay.
Results Interestingly when the PDAC cells were co-cultured with undifferentiated THP1 monocyte-like cells invadopodia formation was significantly suppressed. Moreover, conditioned media of THP1 cells (CM) was also able to suppress invadopodia formation. Further investigation revealed that both tissue inhibitor of metalloproteinase (TIMP) 1 and 2 were present in the CM. However, suppression of invadopodia formation was found that was specific to TIMP2 activity.
Conclusions Our findings indicate that TIMP2 levels in the tumour microenvironment may have prognostic value in patients with PDAC. Furthermore, activation of TIMP2 expressing monocytes in the primary tumour could present a potential therapeutic opportunity to suppress cell invasion in PDAC

Abstract
Background mHealth, the practice of medicine aided by mobile devices is a growing market. Although the offer on Anesthesia applications (Apps) is quite prolific, representative formal assessments on the views of anesthesia practitioners on its use and potential place in daily practice is lacking. This survey aimed thus to cross-assess the Belgian anesthesia population on the use of smartphone Apps and peripherals. Methods The survey was exclusively distributed as an online anonymous questionnaire. Sharing took place via hyperlink forwarding by the Belgian Society for Anesthesia and Reanimation (BSAR) and by the Belgian Association for Regional Anesthesia (BARA) to all registered members. The first answer took place on 5 September 2018, the last on 22 January 2019. Results 349 answers were obtained (26.9% corresponding to trainees, 73.1% to specialists). Anesthesiologists were positively confident that Apps and peripherals could help improve anesthesia care (57.0% and 47.9%, respectively, scored 4 or 5, in a scale from 0 - 5). Trainees were significantly more confident than specialists on both mobile Apps (71.2% and 51.8%, respectively; p = 0.001) and peripherals (77.7% and 45.1%, respectively; p = 0.09). The usefulness of Apps and Peripherals was rated 1 or below (on a 0 to 5 scale), respectively, by 9.5% and 14.6% of the total surveyed population, being specialists proportionally less confident in Smartphone peripherals than trainees (p = 0.008). Mobile apps are actively used by a significantly higher proportional number of trainees (67.0% vs. 37.3%, respectively; p = 0.000001). The preferred category of mobile Apps was dose-calculating applications (39.15%), followed by digital books (21.1%) and Apps for active perioperative monitoring (20.0%). Conclusions Belgian Anesthesia practitioners show a global positive attitude towards smartphone Apps and Peripherals, with trainees trending to be more confident than specialists.
Simulation-based education improves student self-efficacy in physiotherapy assessment and management of paediatric patients

Abstract
Background The Australian Physiotherapy Council mandates that physiotherapy clinical education be sufficient to produce graduates who are competent to practice across the lifespan. Due to a lack of opportunities for paediatric clinical placements, there is a risk of graduates not having the opportunity to develop competency in paediatric physiotherapy. To address this risk, simulation-based education (SBE) has been proposed as an educational strategy to address the placement shortfall. Despite encouraging evidence for its use in physiotherapy education, there is limited evidence supporting its use specifically in paediatric populations. The aims of this research were to investigate the effect of SBE on student self-efficacy in the physiotherapy assessment and management of paediatric clients, and to determine student satisfaction with SBE as a learning strategy.Methods Three interactive SBE sessions were run during the undergraduate paediatric physiotherapy unit at the campus of one Australian university. Self-efficacy was surveyed before and after each session, to determine confidence in clinical skills, clinical decision-making, treatment preparation and planning, communication skills; evaluating and modifying interventions, and interprofessional practice. Student satisfaction with SBE as a learning strategy was surveyed after the final SBE session.Results For the 164 participants included in this study, self-efficacy survey response rate varied from 77-96% for each session. Significant increases in mean student self-efficacy were recorded for all questions (p<0.001). A total of 139 (85%) responded to the learning reactionnaire with 78.6% indicating they were very satisfied with SBE as a learning strategy. Written comments from 41 participants identified ‘experience’ as the primary theme.Conclusion SBE had a significant positive effect on student self-efficacy in the physiotherapy assessment and management of paediatric patients. Students also perceived SBE to be a valuable learning experience. Future research is needed to investigate whether the improvement in self-efficacy achieved through SBE translates into improved student performance during workplace-based clinical placements.
