COMPARATIVE EVALUATION OF THE EFFECT OF PSYCHOACTIVE MEDICINES ON HIPPOCAMPAL THETA AND GAMMA RHYTHMS
Authors: Fokin Yu. V. 
Published: September 2019

The work was performed on cats with electrodes stereotactically implanted in various parts of the brain. The effect of melatonin, atomoxetine and chlorpromazine on cerebral cortex structures with different phylogenetic organization and on the hippocampus in particular was studied.A normalization of FFT-transformed brain electrograms was conducted. The electrograms were recorded under the influence of the agents under study, which exhibit an activating and depressing effect recorded by the main pharmacokinetic points. Although the psychoactive agents demonstrate different neurochemical and clinical-pharmacological properties, their effects are most clearly seen on brain electrograms by the activity of hippocampal θ and γ rhythms that reflect mesolimbic mechanisms. These mechanisms are characterized by uniqueness of action during the entire period of influence, which coincides with the pharmacodynamic and pharmacokinetic data.These manifestations reflect the effect of the studied psychoactive agents on the fundamental mechanisms of the brain consisting, e.g., in the transformation of intracenter relations and the formation of cognitive functions.

This article presents the results of an experimental study of a new domestic preparation “Vitreolon”, an artifi cial vitreous body based on a weakly cross-linked hydrogel. The safety and effi cacy of this product for the treatment of retinal detachment in experimental animals was evaluated in comparison with silicone oil. The tamponade properties of each drug, their effect on the internal structure of the animal’s eye, convenience and safety of use in ophthalmic surgery were investigated. A base for conducting detailed preclinical and clinical trials was prepared.Rabbits of the gray chinchilla breed were chosen for the study, largely because the size of their eye is close to that of the human eye. This fact allowed us to study the effect of “Vitreolon” in an amount approximately equal to that used in clinical conditions. During the experiment, the indicators of ophthalmological examinations of experimental animals were recorded. The physiological state of the animals was controlled daily. The observation period ranged from 3 months (for rabbits with a silicone tamponade) to 6 months (for rabbits with a tamponade using the new hydrogel artificial vitreous body).It is found that “Vitreolon” is not inferior to silicone oil in terms of tamponade properties. Moreover, it boasts a number of signifi cant advantages, such as a lack of emulsifi cation, absence of migration to the anterior chamber of the eye, no effect on the exchange of intraocular fl uid, no effect on the intraocular pressure (IOP), long-term retention of the shape and transparency. The characteristics of the new hydrogel artifi cial vitreous body are close to those of the native vitreous body. The application of “Vitreolon” in ophthalmic surgery will increase the effi cacy of retinal detachment treatment by reducing the recovery time.

« Un endroit désert », d’Alice Munro : les mythes du féminin liés au tissage, à l’inceste et au cannibalisme
Authors: Ventura Héliane 
Published: September 2019

« Un endroit désert » est une nouvelle d’Alice Munro qui figure dans le volume intitulé Secrets de Polichinelle (1995). Fondée sur une énigme que le dénouement n’éclaircit pas, l’intrigue néo-victorienne met en scène une pionnière canadienne d’origine écossaise qui s’accuse du meurtre de son mari alors qu’elle n’en est peut-être pas l’auteur. L’énigme de l’indicible et de l’indéchiffrable dans la nouvelle sera abordée par le biais du mythe.
Le commandement dans la perversion et la phobie : les deux faces du fascinum
Authors: Lévy Alexandre 
Published: September 2019

Dans ce travail, nous questionnons les articulations cliniques et conceptuelles entre l’objet fétiche, propre à la structure perverse, et les manifestations phobiques. La question du commandement, comme rapport impératif, apparaît comme point commun essentiel à ces deux entités psychopathologiques. Ainsi, la phobie semble être un renversement strict du fétiche, ce dernier s’établissant comme rempart devant l’effroi premier de la rencontre avec le sexuel. Notre étude développe précisément la fonction de ce renversement, fonction apotropaïque, mû par un rapport d’injonction et de commandement, fonction retrouvée dans le fascinum , objet d’effroi en puissance, mais usé comme pouvoir de protection. Un cas clinique est présenté à cette occasion, montrant les liens étroits entre phobie et perversion.
Technologies mobiles : quand l’innovation vole au secours des écosystèmes
Authors: VIEIRA Julien , VIEIRA Lise 
Published: September 2019

L’ubiquité est une propriété remarquable des technologies mobiles qui initient de nouvelles pratiques dans le domaine de la protection de la nature. Fondés sur le numérique, les objets connectés changent indéniablement la donne en dotant les défenseurs de la nature de capacités accrues de surveillance et d’analyse. Cela permet ainsi de suivre le rythme de l’un des défis les plus importants de notre ère : la sauvegarde du patrimoine environnemental.Parmi ces technologies, les drones sont une des réalisations les plus innovantes. Notre propos est de poser la question de l’impact de leur usage à des fins civiles sur les normes et pratiques de sauvegarde du patrimoine environnemental. Quels en sont les impacts, les limites, et quelles perspectives peut- on voir se dessiner ? Cette analyse sur les implications de l’utilisation de ces technologies mobiles est effectuée dans une double approche informationnelle et juridique.
L’avenir du Net Art
Authors: Lartigaud David-Olivier , Thély Nicolas 
Published: September 2019

Que reste-t-il des productions de ces dix dernières années dans le domaine du Net Art ? En faisant le choix de l’Internet, les artistes jouent sur les formats d’action et brouillent ainsi les critères classiques de la production et, par conséquent, de la réception. Le problème alors posé est celui de l’immatérialité de l’œuvre d’art : le spectateur n’a plus de trace de l’œuvre, il a plutôt un rapport direct à elle. Le régime d’engagement de la réception devient alors incertain. Regarder un site Internet chez soi n’est pas identique au fait de se déplacer pour consulter un site dans un contexte d’exposition. De même que la présentation d’œuvre en ligne est très différente de leur monstration dans un espace d’exposition connecté au réseau… À travers des œuvres historiques et contemporaines, nous nous interrogeons, dans cet article, sur les formes produites par le Net Art et sur les différentes manières dont ses productions s’articulent avec la vie traditionnelle des œuvres d’art (exposition, conservation).
La littérature numérique
Authors: Bouchardon Serge 
Published: September 2019

Les œuvres de littérature numérique exploitent la matérialité du support à des fins stylistiques et esthétiques. A côté des figures de style classiques, on peut identifier dans ces œuvres des figures spécifiques, que l’on peut qualifier de figures de manipulation. Mais si la rhétorique de ces œuvres est avant tout une rhétorique de la manipulation, celle-ci est étroitement liée à une esthétique de la matérialité. Cette esthétique peut être manifeste à trois niveaux : matérialité du texte, de l’interface et du support. La matérialité offre des prises à l’interacteur. Néanmoins, ce qui caractérise nombre d’œuvres numériques, c’est un jeu sur la perte de prise. Ces œuvres consistent, sur un plan ergonomique, à jouer conjointement de la prise en charge par le dispositif et du contrôle par l’interacteur, mais aussi, sur un plan plus anthropologique, à mettre en place un jeu sur prise et perte de prise.
Jouer/déjouer
Authors: Dall’Armellina Luc 
Published: September 2019

L’étude « Web Art-expérience » s’appuie sur un corpus de douze œuvres réalisées spécifiquement pour le médium Internet. Elles possèdent non seulement les propriétés médiatiques propres à leur milieu (texte, image, son) mais aussi celles, relationnelles, que mettent diversement en jeu(x) leurs auteurs. Pour élaborer cette typologie, j’ai suivi le précepte de Paul Valéry (Variétés) pour qui : “Chercher une méthode, c’est chercher un système d’opérations extériorisables qui fasse mieux que l’esprit le travail de l’es prit”. Ce travail est conceptuellement réalisé par un opérateur, un système. Une typologie peut être l’un de ces outils qui parviennent à différencier singularités et similitudes des objets qu’elle rassemble et relie dans un lieu, un topos. À travers cet article, le Net Art y est esquissé dans ses dimensions médiatiques, technologiques, relationnelles, esthétiques et dans ses modes d’existence, en marge des institutions et d’une économie de l’art qui ne semblent pas aptes à le recevoir.

Authors: Vega Casanova Jair , Tapias Hernández César Augusto , Pérez Quintero Camilo Ernesto 
Published: September 2019

Introducción: En el artículo se discuten elementos estructurales que afectarían los alcances de algunos espacios de interacción social en la radio comunitaria, tales como los escenarios de planeación participativa y comunicación interpersonal que podrían constituir un importante aporte a la construcción de paz en Colombia. Metodología: El estudio de estos espacios se hizo a través de dos viñetas etnográficas: la primera sobre las Juntas de Programación en las emisoras comunitarias del Caribe y, la segunda, sobre los Comités Temáticos Locales de las emisoras del nordeste antioqueño. Literatura sobre intensidades participativas enmarca este proyecto de investigación en una perspectiva histórica y crítica de la comunicación comunitaria para la paz. Discusión y conclusiones: Se concluye que se requiere fortalecer la planeación participativa con un carácter político y que la comunicación interpersonal debe ser la base de una radio que convoca ciudadanos al encuentro y al diálogo para construir la paz.
Call overlapping signals sexual status in Darwin’s frogs
Authors: Serrano Jose M , Guzmán Noé , Penna Mario , Méndez Marco A , Soto-Azat Claudio 
Published: September 2019

Background. In animal reproductive contexts, calling behaviour is mostly performed by males but in species in which females call, it is not known how vocal interaction occurs between sexes, particularly when sexual dimorphism in signals is low, as in cases in which call repertoire is identical but acoustic properties differ. In Darwin’s frog (Rhinoderma darwinii), a species in which males brood larvae inside their vocal sacs, females have higher dominant frequency and shorter calls and notes than males. Since in this species males persist calling after getting pregnant with larvae, different vocal interaction patterns are expected to occur among animals having dissimilar reproductive status.
Methodology. To explore the mechanisms underlying vocal recognition among the different sexual status of R. darwinii, we recorded natural duets between non-pregnant males (NPM), pregnant males (PM) and females (F) and evaluated their evoked vocal response to natural playback stimuli of each sexual status from November to February 2015-2016 in Chiloé island, Chile. Call rate, phase angles, sound pressure level (SPL), number of overlapping calls and delay of overlapping calls were measured to determine differential responses between natural duets and in response to stimuli consisting of natural calls of individuals of different sexual status.
Results. Spontaneous duet interactions occurred mainly between males and no clear differences between duets were detected. In playbacks, call ratios in response to calls of different sexual status were similar. Females decreased their SPL in response to F calls, while F and PM had longer call delays and lower call overlaps between each other. Major differences were observed in call overlap, as the occurrence of this phenomenon was larger in playback experiments than during natural duets. The number of calls overlapped during natural duets was fewer (10.9 %) than during playback experiments (36.8 %).
Conclusions. Our results suggest that in R. darwinii, PM and F signalize their sexual status by decreasing their call overlap and that NPM respond indistinctly to the other sexual status. In general, these differences in selective call overlap between Darwin's frogs arise as a novel mechanism for signal recognition between animal vocal interactions.
Amelioration of Monosodium Glutamate-induced Testicular Damage and Infertility in Male Rats by Water Melon and Cantaloupe Seeds Extract and Juices
Authors: El-Masry Shimaa , Elsayed Mai 
Published: September 2019

Aims: Monosodium glutamate (MSG) is extensively used as food additive and flavor enhancer, there is a growing concern that this may affect the male reproductive system and fertility. The objective of this study is to investigate the effect of MSG on fertility and testes of mature male rats and the ameliorative role of water melon and cantaloupe (seeds extract and juices).
Study Design: Thirty-six male Sprague - Dawely rats (150-180 g) were randomly assigned into six groups (n=6). Group (1): orally administered with distilled water. Group (2): orally administered with 60 mg/kg of MSG. Groups (3 and 4): orally administered with 60 mg/kg of MSG + 200 mg/kg of water melon seeds extract and juice respectively. Groups (5 and 6): orally administered with 60 mg/kg of MSG + 200 mg/kg of cantaloupe seeds extract and juice respectively.
Results: Results showed that administration of MSG for 6 weeks caused abnormalities of semen characteristics, increased DNA damage and up-regulation of caspase3 expression in the testes tissue. Also, the levels of plasma sex hormones were decreased and the oxidant-antioxidant status was disturbed, moreover, MSG caused alteration in the histopathological structures of testicular tissue. Administration of seeds extract or juices of water melon and cantaloupe almost corrected the biochemical and histopathological alteration produced by MSG.
Conclusion: This study concluded that water melon and cantaloupe seeds and juice extracts have an ameliorative role against MSG-induced testicular damage and infertility in rats.

Published: September 2019

Aims: This research aims to determine the ability of Lemna sp. as a phytoremediation agent in absorbing chromium (Cr) in tannery wastewater.
Study Design: A total of 20 fiber tubs with size 80 x 80 x 40 cm3 and volume of 256 L were prepared and filled with 30 L each of the tannery wastewater and 1.75% bio-slurry added with a volume of wastewater as a source of nutrition for Lemna sp.. The number of Lemna sp. which is used for culture was 180 g for each fiber tube.
Place and Duration of Study: Culturing Lemna sp. in tannery wastewater were carried out in Ciparanje Land Fisheries Area of ​​the Faculty of Fisheries and Marine Sciences Universitas Padjadjaran and for chromium analysis were carried out in Center for Natural Resources and Environment Research of Universitas Padjadjaran, between February and March 2019.
Methodology: This research was carried out by culturing Lemna sp. in tannery wastewater for five days with 20 replications and comparing Cr concentrations in tannery wastewater and Lemna sp. at the end and beginning of the research. Chromium analysis results on the tannery wastewater and Lemna sp. the beginning and end of the research on each sample was tested by paired t-test.
Results: by culturing Lemna sp. in the tannery wastewater as phytoremediation agent for five days the results obtained Cr concentration at the beginning of research each for tannery wastewater and Lemna sp. ranged from 0.180 to 0.194 mg/L with an average of 0.187±0.0034 mg/L and 0 mg/kg. While at the end of the research the concentration of Cr in tannery wastewater and Lemna sp. respectively ranged from 0.057-0.075 mg/L with an average of 0.068±0.0044 mg/L and 2.292-2.333 mg/kg with an average of 2.314±0.0101 mg/kg. There was a decrease in Cr concentration by an average of 64.01±1.96% in tannery wastewater and an increase in Lemna sp.. Paired t-test results showed that Lemna sp. which was cultured in tannery wastewater had a significant influence on Cr concentrations in both tannery wastewater and Lemna sp so that there were significant differences in Cr concentrations at the beginning (day 0) and at the end of the research (day 5).
Conclusion: Average ability of Lemna sp. in absorbing and accumulating chromium in the tannery wastewater in the tissue was 2.314±0.0101 mg/kg and the average reduction in Cr concentration in liquid waste was 64.01±1.96%. Utilization of Lemna sp. containing chromium is possible to be used as a food supplement for fish to increase growth due to reduced Cr toxicity by Lemna sp.
