A Case Of Intermediate Toxic Epidermal Necrolysis (Lyell Syndrome) Induced By Hydroxychloroquine Sulfate: A Report

Abstract: Malaria is a parasite disease that is endemic in tropical country as Niger (West Africa). Hydroxychloroquine sulfate (HCQ) is a synthetic antimalarial drug that is very often used to treat connective tissue diseases such as, scleroderma, systemic or discoid lupus erythematosus, rheumatoid arthritis. This drug may induce numerous cutaneous adverse reactions as well as the other anti-malarial drugs. We report on a case of intermediate Lyell syndrome that occurred in the first week of treatment of malaria attack with a young woman, aged 19, following the administration of hydroxychloroquine sulfate.

Study of some factors influencing the efficacy of insecticidal activity of Boscia senegalensis Lam (E.g. Poir) in the control of Callosobruchus maculatus (Coleoptera-Bruchinae), pest of Cowpea (Vigna unguiculata (L.) Walp.

Abstract: In Sahel, Callosobruchus maculatus (F.) (Coleoptera: Bruchinae) is one of the most fearsome pest of Cowpea (Vigna unguiculata Walp). To effectively combat this pest, many authors have advocated leaves Boscia senegalensis, plant commonly used by African producers in the protection of stored products. In this study, the factors that may influence the insecticidal activity of this insecticide plant in the Cowpea storage structures were examined. It is the effect of an increase in the mass of stored seeds, the effect of an increase in the numbers of insects and the effect of shelf life of broy

Réponse au Di-Ammonium Phosphate des Rendements en Feuilles, en Calices et en Graines des Écotypes d’oseille de Guinée (Hibiscus sabdariffa L.) au Niger

Abstract: Au Sahel, l’oseille est cultivee pour ses feuilles, ses graines et ses calices qui constituent une source de revenu pour les producteurs. Les essais ont ete conduits dans les stations de recherche de l’Institut National de la Recherche Agronomique (INRAN) de Tara/Gaya et Tarna/Maradi au Niger au cours des saisons de pluies 2015 et 2016 pour etudier l’effet de fertlisation minerale sur les ecotypes d’oseille. Le dispositif experimental etait un split plot en blocs randomises a quatre repetitions. Deux facteurs ont ete etudies : les ecotypes d’oseille avec six niveaux (E1, E4, E5, E6, E7 et E8) et la fertilisation sous forme de Di-Ammonium Phosphate (DAP) apportee a 3 differentes doses (0kg/ha, 25kg/ha et 50 kg/ha). A la recolte, les rendements en feuilles, calices et graines ont ete evalues dans un carre de rendement de 10m2. Cette etude a montre que l’apport de fertilisation minerale (DAP) a permis d’augmenter les rendements en feuilles de 50%, en calices de 45% et en graines 30% sur le site de Tara/Gaya au cours de deux annees experimentations. Cependant, sur Tarna/Maradi, cette augmentation a ete de 20% comparee aux temoins. La dose optimale de DAP qui ameliore les rendements en feuilles et en calices au niveau des deux sites est de 50kg/ha. Pour les rendements en graines, elle est de 25kg/ha. Les rendements enregistres sur le site de Tara/Gaya etaient superieurs a ceux de Tarna/Maradi au cours des deux annees d’experimentation. Enfin, les rendements ont ete plus eleves en 2015 au niveau des deux sites. In the Sahel, sorrel is grown for its leaves, seeds and calyxes which provide a source of income for producers. The trials were conducted in the research stations of the National Institute for Agricultural Research (INRAN) of Tara/Gaya and Tarna/Maradi in Niger during the 2015 and 2016 rainy seasons to study the effect of mineral fertilization on the sorrel ecotypes. The experimental device was a split plot in randomized blocks with four repetitions. Two factors were studied: the sorrel ecotypes with six levels (E1, E4, E5, E6, E7 and E8) and the fertilization in the form of Di-Ammonium Phosphate (DAP) provided at 3 different doses (0kg/ha, 25kg/ha and 50kg/ha). At harvest, yields of leaves, calices and seeds were evaluated in a yield square of 10m2. This study showed that the mineral fertilization supplement (DAP) allowed increasing leaf yields of 50%, 45% calyx and 30% seeds at the Tara/Gaya site during two years of experimentation. . However, on Tarna/Maradi, this increase was 20% compared to the witnesses. The optimal dose of DAP that improves leaf and calyx yields at both sites is 50kg/ha. For seed yields, it is 25kg / ha. The yields recorded at the Tara/Gaya site were higher than at Tarna/Maradi during the two years of experimentation. Lastly, yields were higher in 2015 at both sites.

A secured resource access management in educational cloud computing environment

Abstract: The paper discusses the problems of data security in the Cloud Computing and proposes an approach based on network technologies and algorithms. The main idea is to establish a criterion of trust between the service provider and the client to control data access and updates which are operated by the owner or a third party. The method allows limiting and filtering the access, to detect corrupted data and proposes corrective action in the case of an illegal access to the cloud computing services. Similarly, this approach examines the strategies to secure the resources through a distributed cloud computing.
