Authors: Souto Lopez Miguel 
Published: January 2020

Cette note de synthèse se concentre sur l’assurance qualité dans l’enseignement supérieur, avec une attention plus particulière sur l’enseignement universitaire européen. Elle abordera dans un premier temps l’histoire de l’assurance qualité dont la naissance se situe aux États-Unis pour se diffuser ensuite vers l’Europe à partir du milieu des années 1980. Dans un second temps, c’est une littérature descriptive et prescriptive au service des politiques publiques qui sera présentée. Dans un troisième temps, sera proposée la synthèse d’une littérature qui s’est intéressée aux différentes transformations de l’université provoquée par l’assurance qualité : celles des missions de l’université, des reconfigurations entre les établissements et, d’une part, le pouvoir politique, et, d’autre part, les étudiants, des modes de gouvernance et d’organisation des établissements, des identités professionnelles.
"Bienvenue en France"... aux riches étudiants étrangers
Authors: Bréant Hugo , Jamid Hicham 
Published: January 2020

« Bienvenue en France » : le gouvernement a choisi de nommer ainsi sa dernière « stratégie d’attractivité pour les étudiants étrangers ». À cette occasion, les droits d’inscription à l’université pour les non-ressortissant·es de l’Union européenne ont été fortement augmentés. Cette mesure s’inscrit dans la droite ligne de politiques migratoires et consulaires restrictives. L’intention de réduire le nombre d’étudiant-es venant d’Afrique, implicite depuis quelques années, prend forme avec une véritable politique de sélection par l’argent.
Les nouveaux riches de la Belle Époque
Authors: Lochak Danièle 
Published: January 2020

La Belle époque a été particulièrement prolifique en variations sur le thème de l’étranger, entre représentations à connotations racistes, tentatives de légitimer une hiérarchie des races et, partant de l’œuvre civilisatrice de la colonisation, délire antisémite d’un Drumont et discours sur l’« enjuivement » de la France qui culmine avec l’Affaire Dreyfus. Dans ce contexte, des termes naissent, aux origines aussi douteuses que l’intention qui les a fait naître. La dénomination de « rastaquouère » notamment, montre du doigt une figure paradoxale : celle de l’étranger au style de vie ostensiblement luxueux, et donc vulgaire, dont la richesse constitue à la fois une menace et une source de profit.
Retention force of zirconia bar retained implant overdenture: Clinical comparative study between PEEK and plastic clips.
Authors: Emera Radwa Mohsen Kamal , Altonbary Gilan Youssef 
Published: January 2020

Aim: This study aimed to evaluate and compare retention force of two implants retained mandibular overdenture with zirconia bar using two different clip materials.
Methodology: 20 completely edentulous patients (8 women and 12 men) with age ranged between 45 and 65 years were selected for this study. All patients received conventional maxillary and mandibular complete dentures. Two implants were inserted bilaterally in the mandibular canine region. CAD-CAM fabricated zirconia bar attachment was used to retain mandibular overdentures. Patients were randomly divided into two equal groups where poly-oxy-methylene (POM) clip was used for Group I and poly-ether-ether-ketone (PEEK) clip for Group II. Retention force was measured at time of overdenture insertion (T0), six months (T6), and twelve months (T12) later.
Results: significant difference was recorded between the two groups in initial retention forces (T0) where PEEK clip group recorded higher retention forces in comparison to POM clip group (P=0.029). However, insignificant difference was observed at (T6) and (T12). Within group comparison of mean retention values at different follow-up periods revealed significant difference for both groups.
Conclusion:
Within parameters of this study, it could be concluded that both POM and PEEK retentive clips can provide comparable retention forces when used with zirconia bar during 12 months period of overdenture use.

The effect of antioxidants against electromagnetic field on enamel microhardness in rats
Authors: Aras Ahmet , Doğan Mehmet Sinan , Yavaş Mehmet Cihan 
Published: January 2020

Aim: In current studies, it is reported that exposure to electromagnetic field (EMF) is related to numerous illnesses. Important parts of our bodies, oral and dental tissues can also be influenced by the EMF. In this study, it was aimed to determine possible negative impacts of EMFs on dental enamel hardness and to test the efficiency of the antioxidant agents against possible adverse effects.
Methodology: In this study, 4-month-old 32 Winster strain Albino rats were used, each weighing 250-300 gr in average. In total, 40 teeth were used from these 32 rats. These teeth were classified into four groups. Group 1 was determined as the control group, and Group 2,3, and 4 were exposed to EMF measured as 2.48 μT magnetic field intensity and 80.3 V / m electric field intensity for 52 days. Ganodermalucidum (20 mg/kg/ day) was applied to the Group 3 together with the EMF. Melatonin (10 mg/kg/ day) was applied to the Group 4 together with the EMF. The teeth pulled out after the euthanasia were embedded into acrylic blocks and micro-hardness test was applied. The normality of the variables was analyzed through the Shapiro-Wilk test. After the homogeneity test, one-way analysis of variance (ANOVA) was used to compare surface micro-hardness (p<0.05).
Results: As a result of the conducted statistical analyses, there was statistically no significant difference among the groups concerning micro-hardness (P>0.05).
Conclusions: It was determined in our study that 52-day exposure to 2.48 μT EMF did not cause any micro-hardness change in the tooth enamels of the rats. It was also observed that the used antioxidant agents did not cause any significant difference.

Introduction: Safe and adequate blood donation is critical in saving millions of lives annually. In many developing including Nigeria, there is paucity of blood donors.
Aim: In this study, we assessed the blood donation practices of tertiary level students in Imo State, South East Nigeria as well as its prevalence and determinants.
Methodology: Multistage sampling technique was used. Stage one involved the stratification of the institutions into universities and non-universities. In stage two, one university and one non -university was selected using simple random method. Stage three involved the selection of study participants from the student registry using systematic sampling method. Self-administered questionnaire was the study instrument. Data analysis was with Statistical Package for Social Sciences (IBM – SPSS) version 20.
Results: Six hundred (600) undergraduates participated in the study. The mean age of the respondents was 21.3 ± 5.0 years. The one year prevalence of blood donation in this study was 13.8% and 63.1% of the non-donors were willing to donate. Respondents aged 15 – 29 years more willing to donate blood compared to those aged 30 – 44 years (OR = 3.03, p = 0.0003), those that were single were 4 times more willing to donate in comparison to those that were married/divorced (OR = 4.02, p < 0.0001). Respondents that were of Catholic faith were also more willing to donate compared to those that were of Pentecostal/Orthodox denomination (OR = 2.72, p = <0.0001). Class distribution and residence were not independent predictors of willingness to donate blood.
Conclusion: From the findings in this study, it was obvious that the willingness to donate blood is far greater than the actual act of donating blood. There is need to continue to reach out to those willing to donate but do not know how to go about it.

AbstractSurvivin is an inhibitor of apoptosis. Aberrant survivin expression occurs in malignant tumors and has often been linked to unfavorable patient outcome. Here we analyzed 12 432 prostate cancers by immunohistochemistry. Survivin immunostaining was regularly expressed at high levels in normal prostate epithelium but expression was often reduced in prostate cancers. Among 9492 evaluable prostate cancers, 9% expressed survivin strongly, 19% moderately, 28% weakly, and 44% lacked it. Loss of cytoplasmic survivin was seen in advanced tumor stage, higher Gleason score, preoperative PSA levels, and Ki‐67 labeling index, and associated with earlier PSA recurrence (P < .0001). Survivin loss was significantly more common in cancers carrying TMPRSS2:ERG fusions (61% survivin negative) than in ERG wild‐type cancers (32% survivin negative; P < .0001). Multivariate analysis revealed that reduced cytoplasmic survivin expression predicted poor prognosis independent from Gleason score, pT, pN, and serum PSA level. This was valid for ERG‐positive and ERG‐negative cancers. Survivin expression loss even retained its prognostic impact in 1020 PTEN deleted cancers, a group that is already characterized by dismal patient prognosis. In conclusion, reduced survivin expression is associated with more aggressive tumors and inferior prognosis in prostate cancer.
Improvement of the Cycling Performance of Aluminum Anodes through Operando Light Microscopy and Kinetic Analysis

Published: January 2020

AbstractAluminum is an attractive anode material for lithium‐ion batteries (LIBs) owing to its low cost, light weight, and high specific capacity. However, utilization of Al‐based anodes is significantly limited by drastic capacity fading during cycling. Herein, a systematic study is performed to investigate the kinetics of electrochemical lithiation of Al thin films to understand the mechanisms governing the phase transformation, by using an operando light microscopy platform. Operando videos reveal that nuclei appear at random positions and expand to form quasi‐circular patches that grow and merge until the phase transformation is complete. Based on this direct evidence, models of the lithiation processes in Al anodes are discussed and reaction‐controlled kinetics are suggested. The growth rate of LiAl depends on the potential and increases considerably as higher overpotentials are approached. Lastly, improved cycling performance of Al‐based anodes can be realized by two approaches: 1) by controlling the lithiation extent, the cycling life of Al thin film is extended from 5 cycles to 25 cycles; 2) the performance can be optimized by adjusting the kinetics. Together, this work offers a renewed promise for the commercialization of Al‐based anodes in LIBs where the performance requirements are compatible with the proposed cycle life‐extending strategies.
Face–to–face interactions between mothers and female infants in wild bearded capuchin monkeys (Sapajus libidinosus)
Authors: Verderane Michele Pereira , Aguiar Rodrigo Mendes , Izar Patrícia 
Published: January 2020

AbstractOnce considered uniquely human, mother–infant face–to–face interactions (FF) were observed in a few captive primates. In these studies, FF were correlated to physical contact suggesting a mechanism mediating proximity between mother and infant, as is the case for humans. We investigated this hypothesis in wild capuchin monkeys (Sapajus libidinosus) during the first year of life of eight female infants. Data were weekly focal‐day videos of infants from which we recorded FF with mothers. We expected FF would increase with infants’ age (as time in contact with mothers decreased) and would more likely occur in the absence of physical contact between the dyad. There was no effect of age in the proportion of interaction time spent in FF, nor in types of FF. A quarter of FF episodes occurred in the absence of physical contact between the dyad, and in most of them physical contact was resumed following the FF. Contrary to predictions, the stability in the first year, mainly when mothers–female infants were in contact, indicates that FF act primarily promoting opportunities for affective communication and intuitive care. However, we found some supportive evidence for the hypothesis that FF regulate proximity between mother and infant, mainly in resume physical contact.

AbstractAdvantame is a novel sweetener, and 3‐hydroxy‐4‐methoxy benzal acrolein is an important intermediate to synthesize the sweetener. The aim of this study was to evaluate a new low‐cost method to purify 3‐hydroxy‐4‐methoxy benzal acrolein, and the crude intermediate was used as raw material. The intermediate was purified using a low‐pressure column chromatography with a C18 column, using a methanol‐water (6:4, v/v) at a flow rate of 6.0 ml/min, and the loading amount of the crude intermediate in solution was 10.0 mg in total. A method for the analysis of 3‐hydroxy‐4‐methoxy benzal acrolein was established using high‐performance liquid chromatography (HPLC). This method was validated in terms of its linearity, repeatability, accuracy, detection limit, and quantitation limit. The calibration curves of 3‐hydroxy‐4‐methoxy benzal acrolein were linear (r > .999) over a wide concentration range of 0.005–0.08 mg/ml, by comparing the ratio of signal to noise, and the detection limit was 5.0 ng/ml and the quantification limit was 15.0 ng/ml. Good repeatability was obtained (RSD < 2%, n = 6), and the recoveries calculated using mixed sample previously quantified ranged from 94.5% to 106.37%. As long as, this method has been successfully applied to the analysis of 3‐hydroxy‐4‐methoxy benzal acrolein; therefore, the method can be put into practical use during the industrial synthesis and real‐time detection of the intermediate.

AbstractBackgroundThis study aimed to investigate the correlation of long intergenic non‐coding RNA 511 (LINC00511) with clinicopathological characteristics and overall survival (OS) in osteosarcoma patients and to explore its function in osteosarcoma in vitro and in vivo.MethodsTumor tissues and adjacent tissues from 45 osteosarcoma patients were acquired, and LINC00511 expression was detected. In vitro, LINC00511 expression was detected in osteosarcoma cell lines and osteoblast cell line. LINC00511 overexpression‐treated (OE‐LINC00511) and nonsense overexpression‐treated (OE‐control) MG‐63 and Saos‐2 cells were cultured, followed by the assessment of cell proliferation, apoptosis, migration, and invasion. In vivo, tumor weight and volume were measured in OE‐LINC00511 and OE‐control xenografted mice.ResultsLINC00511 expression was decreased in tumor tissues compared with adjacent tissues (P < .001), and its high expression correlated with increased tumor cell necrosis rate to neoadjuvant chemotherapy (P = .025) and prolonged OS (P = .010). In vitro, LINC00511 expression was decreased in osteosarcoma cell lines (including MG‐63, U‐2OS, Saos‐2, and HOS) compared with osteoblast cell line (All P < .001). Cell proliferation was decreased at 48 hours (Both P < .01) and 72 hours (Both P < .001) (in MG‐63 and Saos‐2 cells); cell apoptosis was increased (P < .05) (in Saos‐2 cells); cell migration and invasion were decreased (All P < .01) (in MG‐63 cells and Saos‐2 cells) in OE‐LINC00511 compared with OE‐control. In vivo, tumor volume was reduced at week 4 (P < .001), week 5 (P < .001), week 6 (P < .001) in OE‐LINC00511 compared with OE‐control. Tumor weight was declined in OE‐LINC00511 than OE‐control (P < .001).ConclusionsLINC00511 acts as a potential biomarker and therapeutic option for osteosarcoma.

AbstractOver the past century, conversion to agriculture has greatly reduced the global extent of coastal wetlands leading to degradation and loss of these ecosystems. However, it remains unclear how this land conversion affects the confluent soil organic and inorganic carbon (SOC and SIC) storage as well as their localizations in soil matrix. Here, we investigated these issues using wet sieving at two coastal saline–alkali sites in northern China. Conversion of marshes to cropland (>60 years) decreased the portion of large macroaggregates (>2 mm) and correspondingly increased the portion of microaggregates (0.053–0.25 mm) at both sites. Land conversion decreased SOC contents by 31–67% in all fractions (>2, 0.25–2, 0.053–0.25, and <0.053 mm) in the topsoil (0–15 cm) and subsoil (15–30 cm). In contrast, irrigation‐ and NH4HCO3 fertilization‐derived carbonates increased SIC storages in almost all fractions due to the saline–alkali soil conditions, especially for the subsoil. This increases in SIC almost offset and compensate for the SOC losses at both sites. Consequently, the irrigation‐ and NH4HCO3‐induced SIC accumulation should be included in the full C balance of saline–alkali soils. It should be noted, however, that the progressive loss of SOC due to cultivation will lead to soil degradation in fertility and ecological function, thereby hampering long‐term sustainability of coastal ecosystems. Therefore, the compensation of SIC for the loss of SOC is not sustainable in the longer term.
Human menstrual cycle variation in subcortical functional brain connectivity: a multimodal analysis approach

Published: January 2020

AbstractIncreasing evidence suggests that endogenous sex steroid changes affect human brain functional connectivity, which could be obtained by resting-state fMRI (RS-fMRI). Nevertheless, RS studies on the menstrual cycle (MC) are underrepresented and yield inconsistent results. We attribute these inconsistencies to the use of various methods in exploratory approaches and small sample sizes. Hormonal fluctuations along the MC likely elicit subtle changes that, however, may still have profound impact on network dynamics when affecting key brain nodes. To address these issues, we propose a ROI-based multimodal analysis approach focusing on areas of high functional relevance to adequately capture these changes. To that end, sixty naturally cycling women underwent RS-fMRI in three different cycle phases and we performed the following analyses: (1) group-independent component analyses to identify intrinsic connectivity networks, (2) eigenvector centrality (EC) as a measure of centrality in the global connectivity hierarchy, (3) amplitude of low-frequency fluctuations (ALFF) as a measure of oscillatory activity and (4) seed-based analyses to investigate functional connectivity from the ROIs. For (2)–(4), we applied a hypothesis-driven ROI approach in the hippocampus, caudate and putamen. In the luteal phase, we found (1) decreased intrinsic connectivity of the right angular gyrus with the default mode network, (2) heightened EC for the hippocampus, and (3) increased ALFF for the caudate. Furthermore, we observed (4) stronger putamen–thalamic connectivity during the luteal phase and stronger fronto-striatal connectivity during the pre-ovulatory phase. This hormonal modulation of connectivity dynamics may underlie behavioural, emotional and sensorimotor changes along the MC.
