Effets pharmacologiques d’un extrait aqueux de Mirabilis jalapa L. (Nyctaginaceae) sur le système cardiovasculaire, la respiration et l’activité mécanique intestinale de mammifères
K Ndia, F Traore, K Kouakou, E Ehile
Afrique Science: Revue Internationale des Sciences et Technologie , 2009,
Abstract: L’extrait aqueux brut de Mirabilis jalapa (Mj) a des effets hypotenseurs, il active l’amplitude et la fréquence respiratoires du Lapin de 2,19.10-3 à 1,75.10-2 g/kg de P.C. De 4,27.10-4 à 1,54.10-2 g/kg de P.C., cette substance provoque une diminution de l’amplitude des ondes P, QRS et T de l’ECG ainsi qu’une baisse de la fréquence du coeur du Lapin. Ces effets, ainsi que les arythmies enregistrées à 1,54.10-2 g/kg de P.C. de Mj sont pratiquement abolis par l’Atropine à 1,28.10-6 g/kg de P.C. Cet extrait diminue le tonus de base de l’aorte de Cobaye entre 10-10 et 10-1 mg/mL et augmente l’amplitude des contractions rythmiques du duodénum de Lapin à partir de 2.10-4 g/mL. Ces effets rappellent ceux de l’acétylcholine. On en conclut que l’extrait aqueux de Mirabilis jalapa L. (Nyctaginaceae) contient des substances cholinomimétiques, ce, d’autant plus que les effets de Mirabilis jalapa sur l’ECG sont en grande partie abolis par l’Atropine, un inhibiteur compétitif de l’Acetylcholine. Mots-clés : Mirabilis jalapa, Acetylcholine, récepteurs muscariniques
Direct genetic transformation of Hibiscus sabdariffa L.
Yaye Kène Gassama-Dia, Djibril Sané, Mansor N'Doye
African Journal of Biotechnology , 2004,
Abstract: Transgenic Hibiscus sabdariffa plants have been produced by a tissue culture independent method using Agrobacterium tumefasciens transformation procedure. Embryo axes of mature seeds with one cotyledon excised were infected by immersion in a suspension of Agrobacterium LBA 4404 strain culture that carries pBal plasmid with β-glucuronidase p35SGUSINT and plant selectable marker Neomycin Phospho-Transferase gene (nptII). Following a 24 h co-cultivation with Agrobacterium strain and decontamination with cefotaxime, embryos were grown on soil rite containing MS medium added with a killer concentration of kanamycin (100 μg/ml) during 4 weeks at room conditions and thereafter transferred to greenhouse. 54.3% of the seedlings grew well on the selective medium; 68% of the explants excised from putative transformed plants were found to be GUS positive. After 60 days evaluation point, the assessment of the transformation by PCR revealed that H. sabdariffa line tested, carried the nptII gene. Key Words: Hibiscus sabdariffa; genetic transformation.

Commerce et logiques d’acteurs dans la région de Kolda au Sénégal
Néné Dia
EchoGéo , 2009,
Abstract: Dans la région de Kolda, le commerce du lait de vache s'est progressivement développé grace à l’existence des ceintures laitières périurbaines et à la création récente d’un bassin laitier par une société cotonnière désireuse de diversifier ses activités. Ces espaces de collecte révèlent les stratégies des acteurs du commerce du lait. Ainsi les gérants des mini-laiteries et des centres de collecte du bassin laitier mettent-ils en place des processus de collecte et de commercialisation qui varient d'un espace à l’autre, en fonction des moyens financiers et logistiques. Ces stratégies témoignent également de la fragilité des acteurs du commerce laitier. The trade of milk gradually developed in the Kolda region due to the existence of dairy belts and of a dairy basin around Kolda. The organization and the dynamics of these spaces of milk collection reveal the actors strategies. The mini-dairies’s managers and the manifold centers of the dairy basin are developing strategies of collection and marketing which vary from a space to another according to financial means and logistic. hese strategies also reveal the difficulties of the actors.

Pino, Nádia Perez;
Cadernos Pagu , 2007, DOI: 10.1590/S0104-83332007000100008
Abstract: queer theory emerged as a theoretical orientation that challenged current forms of understanding social identities at the same moment when the question of the intersex became socially visible. in spite of this, queer reflection on the intersex is fairly recent. the intersex require reflection on invisible experiences, identity paradoxes and the limits of what we understand as human. in this article, i explore the different definitions of who are the intersex, how queer theory deals with them and i conclude with a reflection on the bodily experience of subjects marked as intersex.
Corpo e outras (de)limita??es sexuais: uma análise antropológica da revista Sexuality and Disability entre os anos de 1996 e 2006
Meinerz, Nádia Elisa;
Revista Brasileira de Ciências Sociais , 2010, DOI: 10.1590/S0102-69092010000100009
Abstract: this article aims at describing the emergence of the interface between sexuality and "deficiencies" as both research and intervention problem. we analyze articles from the international magazine sexuality and disability, published between 1997 and 2006. four articulation perspectives have been identified amidst themes addressing different research matters, specific models explaining such "deficiency," as well as variable positions regarding production, application, and consumption of scientific knowledge. the analysis also points at sexuality as a boundary device, defining the limits between normality and pathology relating to the experience of corporal and psychic/cognitive diversity.

Farage, Nádia;
Revista Brasileira de Ciências Sociais , 1998, DOI: 10.1590/S0102-69091998000300007
Abstract: the article deals with ethical principles which are the grounds for the rhetorical codification of the wapishana, people belonging to the maipura/arawak linguistic branch, and living between the rivers branco and rupununi, at the border of brazil and guyana. according to this codification, there is a necessary link between soul and language, which associates its decorous use - as dialogue par excellence - to the human sociability. through this, the article seeks to establish the wapishana conception of human nature.
