Recherche de composés à activité antiplasmodiale à partir de la biodiversité malgache

Beniddir, Ahmed-mehdi 31 October 2012 (has links) (PDF)
Dans le cadre de la recherche de nouveaux composés à activité antiplasmodiale, deux plantes de Madagascar ont été étudiées : Pyrostria major (Rubiaceae) et Gonioma malagasy (Apocynaceae). Leurs extraits acétate d'éthyle et alcaloïdique ont montré une activité antiplasmodiale significative vis-à-vis de la souche chloroquino-résistante FcB1 lors d'un criblage préliminaire. L'étude phytochimique des feuilles de P. major a conduit à l'isolement du β sitostérol ainsi que de huit nouveaux diarylheptanoïdes glycosylés, décrits pour la première fois dans une plante appartenant à la famille des Rubiaceae. L'activité antiplasmodiale de l'extrait AcOEt des feuilles est probablement due à la présence du β sitostérol. Cette activité serait due à l'effet stomatocytogénique provoqué par cette famille de composés. L'utilisation de l'"Exciton chirality" a permis de déterminer la configuration absolue des diarylheptanoïdes glycosylés isolés. Cette étude structurale nous a permis d'obtenir d'une part, deux composés antiplasmodiaux sélectifs et non cytotoxiques et d'autre part, un composé antileishmanien et un autre antitrypanosomal. L'étude de l'extrait alcaloïdique de G. malagasy a conduit à l'isolement d'une nouvelle série chimique, "les goniomedines". Ces dernières sont caractérisées par un squelette bisindolique constitué de deux monomères dihydroindoliques reliés par une unité dihydropyrane. Une étude configurationnelle basée sur le calcul théorique de spectres de dichroïsme circulaire ainsi que sur des considérations biogénétiques, a permis la détermination de leur configuration absolue. Parmi ces composés, un seul a montré une activité antiplasmodiale significative.

L'enseignement de la langue maternelle malgache au primaire, depuis 1958 : l'enjeu de l'élaboration des programmes scolaires dans un contexte multilingue / The teaching of the Malagasy native language in primary education since 1958 : the challenge of developing school curricula in a multilingual context

Rakotoson, Sahondra Olivia 31 January 2019 (has links)
L’enseignement du malgache, langue maternelle et officielle à Madagascar, se trouve dans une position complexe car il ne permet pas aux enfants issus des classes primaires d’avoir les compétences escomptées en apprentissage de langues. Depuis l’avènement de la première république en 1958, les différents programmes scolaires qui se sont succédé n’affichent clairement ni des dispositions linguistiques face aux différentes variétés du malgache, ni des recommandations méthodologiques répondant aux besoins de l’apprentissage dans le contexte plurilingue où évoluent les élèves malgaches. Le système éducatif actuel devrait donc être revu pour être conforme à l’optique de la didactique intégrée et de l’intercompréhension. Cette thèse s’inscrit dans cette optique. Elle est le fruit des enquêtes et des observations des formations des enseignants ainsi que des pratiques de classes dans plusieurs établissements de Madagascar, menées en 2010-2012. Elle soulève les enjeux politique, pédagogique et didactique de l’élaboration du programme scolaire, qui devrait être le principal outil des différents acteurs pédagogiques. / Teaching Malagasy, which is the native and official language in Madagascar, is in a complex position because it does not enable children who completed primary classes to have the skills expected in learning languages. Since the advent of the first republic in 1958, the various school curricula which have followed one another do not show clearly either linguistic capacities in front of the different varieties of the Malagasy, or methodological recommendations meeting the needs of learning in the multilingual context where the Malagasy pupils are developing. The current education system should therefore be reconsidered so as to be in accordance with the perspective of integrated didactics and mutual understanding. This thesis is part of this perspective. It is the fruit of inquiries and observations based on the training sessions provided to teachers as well as on the classroom practices in several schools of Madagascar, which were conducted in 2010-2012. It raises the political, educational and didactic issues in developing school curricula, which should be the main tool of the various educational actors.

Old testament texts in Malagasy contexts: an analysis of the use of the old testament in three religious contexts in Madagascar

Razafindrakoto, Georges Andrianoelina 30 June 2006 (has links)
The Old Testament, which is one of the first books in the Malagasy language, plays an important role in the religious and cultural life of most people in Madagascar, for instance in an increasing tendency to use Old Testament texts in Malagasy religious contexts, which is noticeable both within and outside mainstream Christianity. The first such case illustrating this trend within the Church is the Malagasy Roman Catholic Church's (MRCC's) application of certain texts in the famadihana (turning of the dead), a custom reflecting traditional Malagasy practices in their strongest form. Almost all the Malagasy churches from their beginning have unsuccessfully attempted to abolish it. Therefore, the MRCC decided to base it on biblical texts and incorporated it in her liturgy in order to make it a Christian celebration. Among the texts used here are: Genesis 49: 33-50: 13; Exodus 13: 19 and Exodus 20: 12. The second case is the Malagasy Lutheran Church's (MLC's) employment of Old Testament texts to create certain items for Nenilava (Tall mother), the founder of the revival movement of Ankaramalaza, who was acknowledged by this Church and the members of this movement as a prophetess and priestess. To demonstrate these roles, and at the same time to confirm her consecration, the MLC and the `children of Ankaramalaza' made for her a priestly robe modelled on the high priest's garments described in Exodus 28 and a silver crown related to Deuteronomy 28. The use of the Old Testament outside the Church is illustrated by the third case, investigating traditio-practitioners' applications of Old Testament texts in their religious practices. Examples include: 1) Exodus 3:1-3; Leviticus 14: 1-8; Jeremiah 8: 22, used in traditional healing; 2) Exodus 3: 5b; Job 33: 6a; Psalm 121: 8a, employed as religious slogans; 3) Leviticus 1-6, applied in traditional sacrifices and offerings; and 4) Psalm 113: 5-6; Genesis 2: 18, 22, employed as references for morality. This project, which describes and analyses how and why the Old Testament is used by different people, Christian and traditionalist, in Malagasy religious contexts, is aimed at developing an interpretive model based on these three cases. More specifically, it seeks to show how the Old Testament can be interpreted and used in contemporary Madagascar/Africa. / Biblical and Ancient studies / D. Th (Old Testament)
