Published: September 2021

El objetivo del trabajo fue identificar a nivel morfológico los hongos asociados al agroecosistema café (Coffea arabica L.), en el estado de Tabasco, México. En campo se seleccionaron al azar 6 plantas de café y se colectaron muestras de hojas tallos y frutos con síntomas visuales atribuidos a hongos. En laboratorio se realizaron aislamientos en medio PDA a partir del tejido enfermo y se obtuvieron cepas puras. Para la caracterización morfológica a nivel de género se emplearon claves especializas (forma, color y tamaño). En total se obtuvieron 47 aislamientos, los cuales fueron distribuidos por órganos de la planta: en hojas hubo 22 aislados con afinidad morfológica con Colletotrichum gloesporoides, tres con Colletotrichum theobromicola, uno con Pestalotiopsis sp, tres con Paramyrothecium roridum, uno con Phomopsis sp, dos Hemileia vastatrix y dos con Marasmius sp; en el cuello de la planta se encontró un Fusarium sp; en el tallo Lasiodiplodia sp y un Colletotrichum gigasporum; en frutos se reportó nueve aislados de Fusarium sp. Se identificaron 11 especies de hongos, asociados al patosistema Coffea arabica L., en sus diversos órganos; de éstos, 10 están reportadas como fitopatógenos este cultivo y uno como patógeno de Theobroma cacao L.
Gas-phase Formation of Cationic Fullerene/Amino Acid Clusters: Evidence for the “Magic Number” Chemical Reactivity of Fullerene Cations

Published: September 2021

Abstract
An experimental and theoretical investigation on the chemical reactivity of fullerene cations (C
n

+, n = [36, 60]) with amino acid molecules (e.g., isoleucine, C6H13NO2) is performed. The results show that, in the gas phase, fullerene cations can react with amino acid molecules to form fullerene/amino acid cluster cations with high efficiency. The formation rate constants for the ion–molecule collision reactions between fullerene cations and isoleucine are estimated under the pseudo-first-order reaction condition. We find the formation rate constants increase gradually with a declining C-atom number of fullerene cations (C
n

+, n = [46, 60]), and depict a plateau in the reactivity for smaller fullerene cations (C
n

+, n = [36, 44]). More importantly, by comparing to its neighbor fullerenes, the magic number of C-atom counts (54, 58) that process with enhanced chemical reactivity are determined. We also obtained the molecular structures and binding energies for the fullerene-monoisoleucine adducts by quantum chemical calculations, which give a good explanation for the magic number chemical reactivity and the enhanced chemical reactivity of smaller fullerene cations. We infer that our results demonstrate the importance of ion–molecule reactions to the formation of large and complex fullerene-amino acid derivatives in the ISM. The high reactivity of fullerene species may indicate that amino acid molecules or other related prebiotic compounds can accrete on small interstellar carbon dust grains.

La solitude ronge-t-elle les membres de votre équipe ?
Authors: Rousseau Alexandre , Bertholet Jean-François 
Published: September 2021

Après un an et demi à travailler à la maison à plein temps, de nombreuses équipes sont habitées par un sentiment de solitude. Avant la pandémie, des chercheurs sonnaient déjà l’alarme : la lutte contre l’isolement 1 est un des plus grands défis du télétravail. Or, même lorsqu’elles sont bien entourées, les personnes qui se rendent chaque jour au bureau peuvent aussi avoir l’impression d’être bien seules.
L’esthétique didigaesque de Bottey Zadi Zaourou, une vision révolutionnaire de la dramaturgie ivoirienne  : le cas de La Tignasse
Authors: Logba Koffi Dominique Konan 
Published: September 2021

Système symbolique, élément symbolique, tableau rythmique et tableau constituent les constantes fondatrices de la structure formelle de La tignasse. Ce vocabulaire dramatique innovant porte l’esthétique dramatique révolutionnaire de Bernard Zadi Zaourou, le Didiga, construite sur le socle du symbolisme. La tignasse est, en effet, un conglomérat de récits qui révèlent, les uns après les autres, telle difformité, telle cruauté, telle laideur de la société africaine post indépendance. La pièce s’inscrit, ainsi, dans les canons du théâtre épique où la satire sociale et le théâtre politique conduisent l’idéologie du dramaturge ivoirien : il souhaite voir l’Afrique, dans sa généralité, amorcer son essor social, économique et politique pour le bonheur de tous ses fils.
Le Doozi, chœur rythmique du Didiga de Zadi Zaourou
Authors: Soupé Lou Touboué Jacqueline 
Published: September 2021

Si le théâtre est mimesis, spectacle, cette forme d’expression artistique existe dans l’Afrique traditionnelle. Ces arts spécifiques aux différentes régions et qui s’apparentent au théâtre ont pour nom : kotéba, mvêt, didiga, etc. Jouant un rôle social, économique, religieux, politique important, ces expressions dramatiques se faisaient, non pas par le théâtre tel que les Grecs vont l’expérimenter et plus tard toutes les sociétés occidentales. Il est, de ce point de vue, évident de les analyser, selon des critères esthétiques propres. Cependant, en tenant compte de l’histoire coloniale de l’Afrique et de l’avènement d’un monde moderne globalisé, il est nécessaire d’inscrire et d’appréhender aujourd’hui ces formes d’expressions dramatiques dans une vision globalisante, dans un choix éclectique. Telle est en réalité la démarche de Zadi Zaourou qui reprend le didiga du pays bété ivoirien pour lui donner un écho plus important et le faire exprimer dans cette société de rencontres. Le didiga est un spectacle dramatique d’initiation, de quête, de l’entre deux, symbolisé par un des personnages récurrents, le Doozi, chœur rythmique du didiga. Parce que sa situation relève toujours de l’extraordinaire, du surréel, Zadi Zaourou, le théoricien du genre, le définit comme un art de l’impensable que cette contribution vise à décrypter.
Macabre et désordre ontologique dans l’œuvre théâtrale de Sony Labou Tansi
Authors: Souâd Kedri 
Published: September 2021

De Conscience de tracteur au Trou, l’écriture dramatique de Sony Labou Tansi questionne les grands problèmes de l’Afrique en mettant en évidence l’image des tyrans, de leurs victimes et du destin catastrophique de ce continent. Ce dramaturge révèle l’envers et l’endroit de l’Afrique à travers une symbolique de la mort globalement empruntée aux attitudes et aux pratiques funéraires traditionnelles négro-africaines. Le macabre traverse donc tout le théâtre de Sony Labou Tansi qui se décline au travers d’une philosophie négro-africaine. Il est cependant symptomatique que l’objectif de cet article est de dégager du texte dramatique tansien, l’enjeu ontologique qui se présente comme des jeux rituels funéraires. De ce fait, nous solliciterons la notion de « rite funéraire », selon la pensée de Louis-Vincent Thomas, pour voir comment le dramaturge congolais se saisit de cette pratique rituelle pour interpréter ce désordre ontologique qui révèle son caractère dévastateur sur l’ordre social.
Écrits pour la parole de Léonara Miano, mis en scène par Eva Doumbia : un spectacle communautaire ou afropéen ?
Authors: Bertin Majorie 
Published: September 2021

Cet article propose d’analyser en quoi devenue pièce de théâtre, Écrits pour la parole de l’autrice Léonora Miano peut être perçue comme une tentative « d’habiter la frontière » par deux Afropéennes (la Camerounaise d’expression française Léonora Miano et le metteuse en scène française d’origine malienne Eva Doumbia) qui questionnent la notion d’identité. Ce spectacle s’inscrirait alors dans la même mouvance que bon nombre d’écritures dramatiques africaines contemporaines qui partagent ce que Sylvie Chalaye analyse, dans Afrique noire et dramaturgies contemporaines : le syndrome Frankenstein (Sylvie Chalaye, Afrique noire et dramaturgies contemporaines : le syndrome Frankenstein, Éditions théâtrales, coll. « Passages francophones », Paris, 2004), comme un refus d’être identifié pour des artistes qui marronnent et « se jouent de tous les masques qui leur sont offerts et qui puisent dans un patrimoine culturel mondial (Ibid., p. 108-109.) » sans tomber dans l’universalisme. Plus largement, cet article esquisse une définition de l’afropéïsme, un concept récent en France, déjà bien aux États-Unis et dans les pays francophones.

Authors: Menon Bindu , Sannapareddy Subram , Menon Medha 
Published: September 2021

Background and Objectives:
The COVID-19 pandemic has a major bearing on mental health. This study was aimed to study the level of stress among the medical and dental students amidst this crisis.

Materials and Methods:
A questionnaire was mailed to students pursuing medical and dental undergraduate and postgraduate degrees across India. It included sociodemographics, psychological status, academic activities, online classes, information about COVID-19, and the Perceived Stress Scale (PSS).

Results:
The overall response rate was 86%. 9.8% of students had low, 74.4% had moderate, and 15.8% had high stress according to PSS. The major worry was uncertain future (41.8%); academic inadequacies/delays (27.78%), apprehension of self-health (26.78%), and family's health (21.13%). 52.7% of participants experienced a lack of motivation; 74% were frustrated/irritable and 46.3% experienced loneliness. Their access to information about COVID-19 was from family and friends (71.42%); news (64.48%), social media sites (62.79%), Internet (36.87%), and newspapers (34.71%). Females were more stressed (P value = 0.000) with ages 21–25 years (P value = 0.000). The students who were motivated, frustrated/irritable, or lonely had high stress (P value <0.01). The students with no exercise had high stress (P value <0.01), however, the duration of exercise was not statistically significant. 58% were not satisfied with the online classes (P value <0.01).

Interpretation and Conclusions:
Our study showed that more than three-fourths of medical and dental students were under moderate to high-level stress. Multiple factors for the stress were identified. Exercise was a stress buster, which should be encouraged for good mental health. In view of the uncertain future identified as the major worry, it is prudent for health educators to change the curriculum to keep pace with the existing competency of training.

Authors: Chhaya Kishti T. , Mankad Saptak , Shah Maulin K. , Patel Mamta , Desai Devangi , Desai Soaham D. 
Published: September 2021

Background:
Headache is a frequently encountered symptom among patients undergoing hemodialysis.

Aim:
The aim of this study was to elucidate the prevalence of hemodialysis associated headache (HDH), its possible etiology, its effect on the patients and steps taken in the management of the condition in Indian patients with end-stage renal disease (ESRD).

Methods and Materials:
A cross-sectional study was carried out amongst 128 consenting patients with ESRD on regular hemodialysis at a tertiary care medical teaching hospital over a period of 3 months to assess for prevalence of HDH and factors related to it. The pre hemodialysis serum electrolytes level, pre and post hemodialysis systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded. Visual analogue scale (VAS) and patient health questionnaire-9 (PHQ9) was administered to the patients. t Test and Chi-square test were applied to find the association between HDH and various postulated factors and a regression analysis was performed.

Results:
Among 128 patients, 48 (37.5%) (men 18 [37.5%], women 30 [62.5%]) were found to have HDH. The mean headache severity scores on (VAS) was 4.5 ± 1.74. Patients having HDH had their mean PHQ9 scores 7.56 ± 4.51. Most patients had headaches in the first hour of dialysis and were located in the frontal and temporal part of the head. No statistically significant difference was found in the electrolyte levels between patients having HDH and without HDH. The headache was moderate in most but needed a paracetamol tablet to relieve the headache.

Conclusion:
Nearly one-third of patients undergoing dialysis have HDH, and it is associated with mild to moderate depression. The factors leading to HDH and its management need to be evaluated further to improve the quality of life of patients with ESRD on dialysis.

Published: September 2021

BACKGROUND:
Previous studies have reported increased levels of inflammatory mediators in patients with obstructive sleep apnea (OSA), but their relation with the severity of OSA is controversial.

OBJECTIVE:
To address potential relationships between OSA-related inflammatory markers, namely, C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and fibrinogen, with different oxygenation parameters and with BMI.

METHODS:
All eligible patients with suspected OSA newly referred to the Sleep Medicine Research Center at King Abdulaziz University Hospital, Jeddah, were evaluated demographically and anthropometrically, and underwent overnight polysomnography. Fasting morning blood samples were collected to measure serum levels of CRP, fibrinogen, TNF-α, and IL-6. Potential correlations between these inflammatory mediators and severity measures of OSA and body mass index (BMI) were explored.

RESULTS:
Sixty-four patients completed the study (40 with OSA and 24 without OSA). Significantly increased levels of CRP, fibrinogen, IL-6, and TNF-α emerged in patients with OSA compared to non-OSA. Significant associations between log CRP and log fibrinogen levels emerged with increasing BMI. However, there was no significant association between any of the inflammatory markers and the severity of OSA based on the apnea/hypopnea index or oxyhemoglobin saturation-derived parameters.

CONCLUSIONS:
OSA patients exhibit increased levels of inflammatory mediators that do not appear to be associated with polysomnographic measures, but exhibit positive correlation with the degree of adiposity.

Authors: Pawar Deepali , Thomas Raison , Shah Rucha , Mehta Dhoom Singh 
Published: September 2021

Introduction:
The present cross-sectional survey study conducted to assess the type of periodontal treatments being done by dental practitioners or specialist other than periodontists and to assess the types and frequency of cases being referred to the Periodontist in the city of Davangere, Karnataka state.

Materials and Methods:
The proposed study was carried out by asking various dental practitioners other than periodontists to fill a structured questionnaire containing 7 questions focusing on several clinical and nonclinical periodontal scenarios, whether they would treat the patient in the office or refer/consult to a periodontist. A population of 64 was studied which comprised of 31 general dentists, 33 specialists and obtained data were then subjected to analysis.

Results:
Most of the private practitioners (82.8%, 53/64) carry out nonsurgical periodontal therapy in their clinics. Among the surgical periodontal procedures, gingivectomy and gingivoplasty are the most commonly performed (40.65, 26/64) surgical periodontal therapy. Around 71.9% (46/64) of practitioners refer or consult their periodontists for the surgical periodontal procedures. Flap surgery is the most commonly performed procedure by the periodontist. The frequency of referring or consulting periodontist is more among dental specialists (P = 0.03). Majority of practitioners, i.e., 65.6% (42/64) feel that there are few patients with periodontal disease who get motivated for periodontal treatment whereas 42.2% (27/64) believe that cost-effectiveness of the periodontal treatment is responsible for such referral pattern.

Conclusion:
It was concluded that our survey study shows that most of the dental practitioners in Davangere city carry out non-surgical periodontal therapy in their clinic and more than half of the dental practitioners refer or consult to their periodontists for surgical periodontal therapy. However, the frequency of referring or consulting the periodontist is low.

Authors: Brígitte Giovanna Tomczinski Novellini 
Published: September 2021

O ensino de BIM deve associar-se à formação das habilidades e competências do egresso. Neste sentido, este artigo defende que os métodos de ensino-aprendizagem podem ser potencializados através de BIM, não apenas no desenvolvimento e avaliação de competências que expressam habilidades e conhecimentos técnicos, mas também, às competências intrapessoais e interpessoais que definem o saber-agir e torna-o capaz de mobilizar um conjunto integrado de recursos em prol da melhor solução mediada por BIM. Metodologicamente fundamenta-se no método exploratório com discussão teórica aliada à prática pedagógica, terminando com uma reflexão sobre o impacto da introdução deste tipo de integração e colaboração na formação em Arquitetura e Urbanismo.

Published: September 2021

En el estudio se hace un primer balance de la introducción de la
cuestión prioritaria de constitucionalidad en el sistema francés. Se analiza el mecanismo
de control, sus requisitos y su impacto sobre la relación entre jurisdicción
ordinaria y jurisdicción constitucional. Esta reforma ha sido el trasfondo de
los enfrentamientos entre Conseil Constitutionnel y Cour de Cassation a raíz del
planteamiento de la cuestión prejudicial en el asunto Melki. A partir del estudio de
la reforma constitucional y de las circunstancias del citado caso se proponen mecanismos
que compatibilicen las potestades de los altos Tribunales franceses en el
marco de los retos del Tratado de Lisboa.
Azterlan honek sistema frantsesean konstituzionaltasunaren
lehentasunezko gaia sartzearen lehen balorazioa egiten du. Kontrol mekanismoak

arteko harremanean duen eragina ere. Erreforma hau egon da Frantziako
Kontseilu Konstituzionalaren eta Kasazio Auzitegiaren arteko liskarren atzean,
Melki auzian epaiketa aurreko auziaren planteamenduak eraginik. Konstituzioaren
erreformaren eta aipatutako kasuaren inguruabarren azterketa abiapuntu hartuta,
Frantziako goi-auzitegien eskumenak bateragarri egiteko mekanismoak proposatzen

This study seeks to draw a first balance of the priority preliminary
ruling on the issue of constitutionality in the French legal order. It analyzes the
control mechanism, its requirements and its impact on the interrelations between
ordinary courts and the constitutional court. The priority preliminary ruling on the
issue of constitutionality has led to the conflict between the Conseil constitutionnel
and the Cour de Cassation due to the preliminary reference in the Melki case.
By analyzing the constitutional reform as well as the circumstances of the above
said case, this study aims to propose mechanism that might reconcile France's supreme
courts in the framework of the Lisbon Treaty.
