Elaeis guineensis Jacq. (Arecaceae), encore appelée Palmier à huile, constitue une source de nourriture et un remède naturel contre plusieurs pathologies. La présente étude avait pour but d’évaluer l’activité cicatrisante de l’extrait aqueux des feuilles de E. guineensis dans un modèle de brûlures expérimentales de second degré chez le rat de souche Wistar. Deux pommades à 3 et 10% de l’extrait aqueux dans la vaseline (EGV-3% et EGV-10%) ont été utilisées pour le test. Au plan phyto-chimique, l’extrait aqueux renferme des tanins, des flavonoïdes, des alcaloïdes et des stérols-triterpènes. L’application quotidienne des pommades induit une cicatrisation dépendante de la concentration. La vitesse de cicatrisation est plus importante avec EGV-10%, qui induit une réparation tissulaire quasi complète au bout de 22 jours de traitement. Les résultats de cette étude montrent l’intérêt de l’utilisation en milieu traditionnel des feuilles de E. guineensis dans la cicatrisation des plaies et des brûlures.Mots clés : plantes médicinales, brûlures, plaies, cicatrisation

 

English Title: Wound healing activity of the aqueous leaf extract of Elaeis guineensis Jacq. (Arecaceae)

Elaeis guineensis Jacq. (Arecaceae) still called Palm Oil, is a source of food and a natural remedy against several diseases. The purpose of this study was to assess the healing activity of the aqueous leaf extract of E. guineensis in second-degree experimental burn model in Wistar strain rat. Two ointments (3 and 10%) of the aqueous leaf extract in the vaseline (EGV-3% and EGV-10%) were used for the test. Phyto-chemically, the aqueous leaf extract contains tannins, flavonoids, alkaloids and sterols-triterpenes. Daily application of ointments promotes a concentration-dependent healing. The cicatrization rate is higher with EGV-10%, which induces near-complete tissue repair after 22 days of treatment. These results show the value of traditional using of E. guineensis leaves in the healing of wounds and burns.Keywords: medicinal plants, burns, wounds, cicatrization.

En Afrique subsaharienne, les infections transmissibles par la transfusion sanguine comme la syphilis sont très répandues, avec une prévalence pouvant atteindre 25% chez les donneurs de sang. La présente étude avait pour objectif de déterminer la prévalence de la syphilis chez les donneurs de sang au niveau de la Banque du Sang d’Abéché. Nous avons mené une étude transversale à visée descriptive, qui s’est déroulée de mai à août 2017. Les échantillons de sang des donneurs ont été testés par immunochromatographie pour la détection des anticorps anti-tréponémiques (Biomnis®). Sur 789 donneurs de sang inclus dans l’étude, la prévalence de la syphilis était de 4,9 %. Les donneurs étaient à 96,1% de sexe masculin et 3,9% de sexe féminin. Cette prévalence était plus élevée chez les sujets âgés de [21-30] ans, chez les femmes, les donneurs non scolarisés, divorcés et les domestiques/ménagères habitant la zone d’Abéché urbaine. Ces résultats montrent qu’il est nécessaire de mettre en place une politique de suivi et de prise en charge médicale des donneurs de sang atteints de la syphilis.Mots clés: Transfusion sanguine, receveurs, Treponema pallidum, don de sang.

La culture de l’oignon contribue fortement à la sécurité alimentaire et à la lutte contre la pauvreté au Burkina Faso. Cependant, plusieurs contraintes dont les pertes post-récoltes entravent le développement de cette filière. L’objectif de cette étude était d’évaluer l’impact d’un procédé de séchage sur la qualité de l’oignon. L’oignon après parage, a été prétraité (NaCl à 5%) ou non, puis séché avec un séchoir à gaz Atesta (60-65 °C, 10-12 h). Les caractéristiques nutritionnelles et microbiologiques des produits frais et séchés ont été déterminées par des méthodes standardisées. Sur la base de la matière sèche, les résultats ont donné pour l’oignon frais, 5,19%, 1,7%, 12,16% et 47,56%, respectivement pour les cendres, matières grasses, protéines et sucres totaux. Après séchage, les teneurs ont varié respectivement de 2,96 à 31,31%, de 0,59 à 0,77%, de 3,58 à 7,78% et de 36,88 à 49,56% pour les cendres, matières grasses, protéines et sucres totaux. Malgré l’effet du prétraitement et du séchage, les teneurs en fer, manganèse, magnésium, zinc et calcium sont restées intéressantes. Les oignons séchés, en l’occurrence ceux prétraités avec le sel étaient de bonne qualité microbiologique. La vulgarisation de cette technologie permettra une meilleure valorisation de l’oignon au Burkina Faso.Mots clés : Séchoir à gaz, procédé, qualité, Burkina Faso.

The production of onion greatly contributes to food security and the fight against poverty in Burkina Faso. However, several constraints including post-harvest losses hinder the development of this sector. The objective of this study was to assess the impact of drying process on the quality of onion. Onion after trimming, was pretreated (NaCl at 5%) or not and dried with a gas dryer Atesta (60-65 °C, 10-12h). Nutritional and microbiological characteristics of fresh and dried products were determined using standard methods. Based on the dry mater, results showed that fresh onion contains 5.19% of ash, 1.7% of fat, 12.16% of proteins and 47.56% of total sugars. After drying, ash, fat, proteins and total sugars content varied from 2.96 to 31.31%, 0.59 to 0.77%, 3.58 to 7.78% and 36.88 to 49.56%, respectively. Despite the effect of pretreatment and drying process, the content of iron, manganese, magnesium, calcium and zinc remained interesting. The dried onions, in particular those pretreated with salt presented good microbiological quality. The dissemination of onion drying technology will allow to add value to onion in Burkina Faso.Keywords: Gas-drier, process, quality, Burkina Faso.

La distribution et la dynamique des populations des tiques est un élément clé dans la connaissance des maladies transmises par ces vecteurs. C’est ainsi que cette étude a été conduite afin de mieux connaître l’épidémiologie de la Fièvre Hémorragique de Crimée-Congo (FHCC) dans les 8 communes du département de Boboye au Niger, où 355 sérums de bovins ont été collectés. En plus des sérums, des tiques ont été collectées sur 144 bovins, soit 18 par commune. Les sérums ont été soumis à un test ELISA (Enzyme Linked Immunosorbent Assay) indirect pour la détection d’anticorps anti-FHCC. Soixante-douze (72) éleveurs ont été interviewés sur leur connaissance de l’écologie des tiques, vecteurs du virus de la FHCC. Les résultats de l’enquête ont révélé que les éleveurs n’ont pas recours aux acaricides et que, dans leur majorité (55/72 soit 76,4 %), ils pratiquent la transhumance. L’étude a permis l’identification de 1342 tiques réparties en trois genres : Hyalomma (91,7%), Amblyomma (5,7%) et Rhipicephalus (Boophilus) (2,6%). La séroprévalence globale a été de 9,1±0,03%. Les communes de Harikanassou et Kiota ont été celles où les fortes prévalences ont été observées de 26,7 ± 12,9% et 22,5 ±12,9%.

English Title: Crimean-Congo Hemorrhagic Fever (CCHF) ’s Epidemiology in cattle in Boboye’s department of Niger Republic

To understand disease transmission by ticks, knowledge of population dynamics and distribution of these vectors are essentials. To sought that, the epidemiology of Crimean-Congo Hemorrhagic Fever (CCHF) in Niger Republic was studied by sampling 355 bovines (sera and ticks) in eight (8) local governments in Boboye’s department. Eighteen (18) bovines were sampled for ticks collection per local government making them a total of 144 bovine. Indirect ELISA test (enzyme-linked immunosorbent assay) was used to detect anti- CCHF antibodies. Seventy-two (72) farmers were surveyed on their knowledge on ticks’ ecology, main vectors of CCHF virus. The results revealed that farmers are not using acaricides, and their majority (55/72 thus 76.4%) practice Transhumance. The study allowed the identification of 1342 ticks distributed in 3 genus: Hyalomma (91.7%), Amblyomma (5.7%) and Rhipicephalus (Boophilus) (2.6%). The global seroprevalence against CCHF was (9.1 ± 0.03) %. Harikanassou and Kiota were the most affected local governments with respectively (26.7±12.9) % and (22.5±12,9) % prevalence. CCHV virus is circulating in animal population, so investigations must be made in human population.

Authors: Odoemene Akachi
Published: July 2020

Ọjị (kola nut) is indispensable in traditional life of the Igbo of Nigeria. It plays an intrinsic role in almost all segments of the people‟s cultural life. In the Ọjị Ezinihitte festivity the „kola tradition‟ is meaningfully and elaborately celebrated. This article examines the importance of Ọjị within the context of Ezinihitte socio-cultural heritage, and equally accounts for continuity and change within it. An eclectic framework in data collection was utilized for this research. This involved the use of key-informant interviews, direct observation as well as extant textual sources (both published and un-published), including archival documents, for the purposes of the study. In terms of analysis, the study utilized the qualitative analytical approach. This was employed towards ensuring that the three basic purposes of this study – exploration, description and explanation – are well articulated and attained. The paper provided background for a proper understanding of the „sacred origin‟ of the Ọjị festive celebration. Through a vivid account of the festival‟s processes and rituals, it achieved a reconstruction of the festivity‟s origins and evolutionary trajectories and argues the festival as reflecting the people‟s spirit of fraternity and conviviality. Furthermore, in surveying the festival‟s dynamism within Ezinihitte society over time, it established that the Ọjị festival is not only a unifying factor but also lies at the heart of community development efforts in Ezinihitte clan.

The Ibero-Guanche (Latin) rock inscriptions found at Mt. Tenezara volcano (Lanzarote, Canary Islands, Spain): A Saharan hypothesis for Mediterranean/Atlantic Prehistory
Authors: Arnaiz-Villena Antonio , Medina Marcial , Ruiz-del-Valle Valentín , Lopez-Nares Adrian , Rodriguez-Rodriguez Julian , Suarez-Trujillo Fabio
Published: July 2020

Two of the several rock script panels found at Mt. Tenezara volcano slope, Lanzarote Is. (Canary Islands) have been analyzed. Both of them contain a linear writing which corresponds to the ancient Iberian semi-sillabary discovered by Gomez-Moreno in 1949 AD, thus to Iberian-Guanche inscriptions which previously were referred as Latin. Ancient Iberian scripts have been found in France, Portugal, Spain and other Mediterranean places during the 1st millennium BC and the following four centuries AD; it may be possible that Iberian signs could have been taken or used at the same time at Africa. Even one of the semi-vertical panels considered as Lybic is in fact written in Iberian-Guanche characters. Also, Mt Tenezara shows Cart-ruts pointing to Equinoxes Sunrise. Findings are put in the context of a Sahara relatively rapid desiccation and a massive people migration to establish several classic and pre-classic civilizations, like Sumer, Egypt, Hittite, Hellenistic, Iberians, Lybic and Canary Islands Guanches, and possibly other Old Atlantic Celtic ones. Saharan Hypothesis is based on Geology, Columbia Shuttle (1981) infrared photographs that show prehistoric desert fertility, Prehistory, Anthropology and Linguistics. A fertile and heavily populated Sahara existed before 6,000 years BC.

Published: July 2020

Purpose: To investigate the analgesic effects of oxytocin (OT) and elucidate the role of dopaminergic system in its mechanisms.Methods: In this study, 72 male (n=6 for each group) 230-250 gr Wistar Albino rats were used. Firstly, dose studies were performed with 100 μg/kg, 200 μg/kg and 400 μg/kg to determine the optimal analgesic effect of oxytocin. Optimal dose was found at 200 μg/kg, and then animals were divided into nine groups: Saline, D1 agonist (SKF 38393; 0.1 mg/kg), D1 antagonist (SCH-23390; 0.1 mg/kg), D1 agonist + oxytocin, D1 antagonist + oxytocin, D2 agonist (Cabergoline; 0,5 mg/kg), D2 antagonist (Sulpride; 10 mg/kg), D2 agonist + oxytocin and D2 antagonist + oxytocin. Serum physiologic saline was given to the saline group and other drugs were administered intraperitoneally at the indicated doses. Tail-flick and hot-plate tests were used to measure analgesic effects. Analgesic tests were measured in 30 min-intervals (at 30th, 60th, 90th, and 120th min) and recorded in seconds. To evaluate maximum antinociceptive effect (% MPE), the tail-flick and hot-plate latencies were converted to the antinociceptive effectivenessResults: The results show that D1 antagonist SCH-23390 (0.1 mg/kg) and D2 agonist cabergoline (0.5 mg/kg) created strong analgesia while the D1 agonist SKF 38393 (0.1 mg/kg) and D2 antagonist sulpiride (10 mg/kg) did not have any analgesic effect. However, only D2 antagonist sulpiride blocked the analgesic effect produced by OTConclusion: OT may be one of the primary agents participating in spinal analgesia, and the dopaminergic system is one of the central mechanisms of action for this important molecule. The dopaminergic system may also be one of the targets for ‘descending’ analgesic system.

Married to God- the Jogin System in India
Authors: Pande Rekha
Published: July 2020

This paper uses the material from a Project of the Ministry of Women and Child Welfare, which we undertook in 1991-92, related to the study, rehabilitation and organizing of Jogins in Andhra Pradesh in India. As researchers, we faced a lot of dilemma while making the research design and evolving a methodology for the study. Jogins are the modern form of the traditional Devadasi system, which existed in India from the 10th century. Dedicated to the temple to carry out various temple-related duties, these girls were married to an immortal God, and since they could never become widows, they were regarded as auspicious ones. Centuries later, by the time India was colonized, all these girls were practicing prostitution. The system was finally abolished in 1947 by law. In spite of this, a large number of women and girls, especially from the lower castes, continue to be dedicated to God in different regions of southern India, especially in Andhra Pradesh and Karnataka. These girls become the keep of the village headman through whom they have a number of children. Since the whole system is institutionalized under the wraps and cover of religion, the exploitive aspect of the institution is often missed. As most of these women are from marginalized sections of society and are also employed as wage labourers and live below the poverty line, they are merely seen as labourers. Their main identity gets subsumed under this category, but here too they are invisible and are marginalized and often missed by policy makers and researchers. This paper documents the experiences of these marginalised and often forgotten women.

Secondary Acute Myeloid Leukemia (s-AML) refers to the development of leukemia after cytotoxic therapy, immunosuppressive therapy, radiation or an antecedent hematological disorder, such as Myelodysplastic Syndrome (MDS). A s-AML corresponds to 10% to 30% of AML cases and is defined by the presence of at least 20% of blast cells, representing a category of disease with a poor prognosis. Allogeneic hematopoietic stem cell transplan­tation (Allo-HSCT) is the only option with curative potential for patients with s-AML, but recurrence after HSCT emerges as a frequent cause of treatment failure and course with high mortality. We report the case of a patient with s-AML after MDS, who underwent HSCT due to refractoriness to other treatments, recovering the bone marrow with dysplasia, be­ing classified as AREB1.
Evaluation of platelets transfusion in patients undergoing high dose chemotherapy for bone marrow transplantation
Authors: Bastos Victor Quinet de Andrade , Leal Christianne Tolêdo de Souza , Ferreira Mariana , Ribeiro Luiz Cláudio , Hallack Neto Abrahao Elias
Published: July 2020

Introduction: Microvascular endothelial damage is a well-recognized complication of bone marrow transplantation (BMT) and the mechanisms of this disorder are still poorly under­stood. The objective of this scenario is to evaluate the relationship between inflammatory markers and other factors that influence platelet consumption and platelet transfusion yield, as well as the presence of embolic and / or vascular thrombotic events in patients submitted to high-dose chemotherapy conditioning for Bone marrow transplant.

Material and Methods: Prospective analysis of patients, including 25 patients who under­went autologous and allogenic BMT. The patients were evaluated in relation to previous radiotherapy, CD34 + cell count, period of neutropenia, body mass index (BMI), ferritin, re­active C protein (RCP), relating these factors to the number of platelet transfusions, plate­let refractoriness and vascular events such as sinusoidal obstruction syndrome (SOS) and bone marrow grafting syndrome.

Results: Only BMI> 25 Kg / m2 of the studied variables presented a statistically significant value (p = 0.003) in relation to the lower need for transfusion of platelet concentrate. For platelet refractoriness and / or vascular events none of the variables was statistically sig­nificant. The conditions found in the 3 cases of platelet refractoriness and in the 2 cases of vascular events have characteristics like those described in the literature.

Conclusion: Although the cause is unclear, we agree with data reported in the literature that patients with high BMI have a lower need for transfusion of platelets. Small sampling limits our comparisons and significant statistical inference; however, we cannot rule out the relevance of a descriptive analysis of the results, especially if we consider that each patient should be evaluated in an individualized way in clinical practice.
Review Article on Emergency Obstetric Care
Authors: Ochejele Silas
Published: July 2020

Maternal death was once a common occurrence worldwide but today, 99% of maternal deaths occur in low income countries. Most of the maternal deaths are due to direct obstetric complications. Emergency obstetric care is the intervention required to save the lives of these women. It is based on a tripod of signal functions, skilled birth attendants and a functional health system. The objective of this article was to discuss the role of Emergency obstetric care in maternal mortality reduction. A systematic review of available articles on Emergency obstetric care; and Emergency obstetric care training materials, experience and observations used/made between 2003 and 2017 in Nigeria was used for this work. Emergency obstetric care is the nucleus on which all other maternal mortality reduction activities are hinged. The paradigm evolvement of Emergency obstetric care offers the last hope for a woman with direct obstetric complication. However, the skilled birth attendant must have the right attitude in addition to her/his professional skills for effective implementation of these interventions. Women need access to and availability of Emergency obstetric care as well as a continuum of care that includes antenatal, intra-partum and postnatal care, newborn care and family planning services to reduce maternal mortality.

Published: July 2020

Perovskite solar cells have gained significant attention in photovoltaic research. Just within a few years, the efficiencies of perovskite-based solar cells have been improved significantly to over 20% which makes them comparably efficient to silicon-based solar cells. The reason for such high recorded efficiencies are due to perovskites ease of processing, a high carrier diffusion length, low exciton binding energy and high absorption coefficient. Theoretical calculations were carried out based on the detailed balanced model on some Tin Halide Perovskite absorbers. For CH3 NH3 SnI3 , results obtained for V oc, Joc , FF and n are 1.14V, 34.4 mA/cm 2, 0.725and 5.56% respectively. For CH3 NH3 SnIBr2 values obtained for  Voc , J oc, FF are 1.37V, 24.03mA/cm2, 0.784 and 5.22% respectively.

La presente investigación tiene como objetivo modelar la interacción del océano-atmósfera utilizando la relación entre la Oscilación del Sur y los eventos El Niño-La Niña como un sistema de entrada-salida. El modelamiento estadístico de este tipo de relaciones requiere del análisis de la función de correlación cruzada entre las series de entrada y salida. Los datos considerados corresponden a series de tiempo mensuales del Índice de la Temperatura Superficial del Mar de la Región del Niño 3.4 y del Índice de la Oscilación del Sur entre 1982 y 2015. Para representar la interacción del océano-atmósfera, se desarrollaron Modelos de Función de Transferencia y de retroalimentación. La eficiencia de estos modelos con datos hasta el 2015 fue comparada para pronosticar hasta septiembre del año 2019 por medio del error cuadrático medio de predicción, encontrando que el modelo de retroalimentación es más eficiente.
Method for analyzing the stability of information transfer between unmanned aerial vehicles in the formation
Authors: Vasilyev G. S. , Kuzichkin O. R. , Kurilov I. A. , Surzhik D. I.
Published: July 2020

The use of a formation consisting of adaptive autonomous mobile agents allows solving a wide range of tasks that are often beyond the capabilities of individual agents. A multi-agent formation is a complex high-order dynamic system, so analyzing the stability of such a system is a complex task. At present, the problem of estimating the stability of a formation formed by substantially nonlinear high-order agents with variable dynamic parameters is not sufficiently considered. This task is particularly important for a formation that is affected by complex unstable environmental conditions, in particular for the formation of unmanned aerial vehicles (UAVs). A method for analyzing the stability of formations of nonlinear agents with different types and orders of transfer function has been developed for studying information exchange in UAV networks. The new approach is based on the use of the Popov frequency criterion and the piecewise linear approximation of the hodograph. A computational experiment was performed to analyze the stability of a formation with transfer functions of various types and orders from the 1st to the 10th. The conducted studies revealed a significant difference in the calculated boundary coefficients of formation stability in the linear and nonlinear modes, which confirms the need to analyze the nonlinear stability under the influence of strong destabilizing influences on the formation.

The objective of this article was to study the effect of geographical features and geological formations on some physicochemical properties of soils in order to better identify the soil and optimize land management for sustainable agriculture in the southern part of the plain. Urmia, with an area of 35000 (ha) in the province of Western Azarbaijan, Iran. In this investigation, satellite images, aerial photographs, topographic and geological maps were used to identify and distinguish different land forms, soil series classified based on geomorphological and geophysical methods. 30 soil profiles were drilled and the FAO standard dimensions were described. Samples were taken from five soil profiles in each genetic horizon and transferred to the laboratory. The soil moisture and temperature regime was determined as Xeric and Mesic. The soils of the studied area were classified as Fluventic Inceptisols and grid subgroups. The most dominant formations in the Barandoz and Ghasemlou river basins were limestone and lime, which is one of the determining factors in rock formation in different soils in the study area. On the other hand, physiography and topography have also played an important role, so that the upper terraces have more developed soils and some sloping regions have younger and less developed soils. With the decrease in height and proximity to Lake Urmia, the effect of the groundwater level and its salinity on the profiles is evident.
