Impact de la Restauration des Zones Dégradées sur la Diversité Floristique de la Forêt Classée d’Agbo 2 en Côte d’Ivoire

La présente étude, menée dans la forêt classée d’Agbo 2 d’une superficie de 4705 hectares, est située au Centre-Est de la Côte d’Ivoire. Cette étude a pour objectif d’améliorer les connaissances sur la valeur écologique de la forêt classée d’Agbo 2. Pour ce faire, des dispositifs d’échantillonnage surfaciques ont été installés et des inventaires itinérants ont été réalisés. Ces deux méthodes ont permis de recenser 121 espèces végétales dont 13 sont des espèces vulnérables inscrites sur la liste rouge de l’UICN. La flore du stade mature des plantations de Teck et de Gmélina ressemble à celle des forêts enrichies avec le Fraké, qui ajoutée aux forêts enrichies avec le Bété sont similaires floristiquement avec les forêts naturelles. De parmi les zones restaurées, les forêts enrichies en espèces locales (Bété et Fraké) sont plus riches et plus diversifiées que les plantations avec les espèces exotiques (Teck et Gmélina). Les forêts dégradées et les zones de restauration abritent des espèces qui doivent être pris en considération lors des études, car elles représentent un écosystème avec une large gamme d’espèces ayant d’importantes valeurs pour le bien-être des populations. La restauration des espaces dégradés par enrichissement serait la méthode appropriée pour un retour à la végétation originelle.   This study was carried out in the 4705 hectare Agbo 2 classified forest in central-eastern Côte d'Ivoire. The aim of the study was to improve knowledge of the ecological value of the Agbo 2 classified forest by installing surface sampling devices and carrying out itinerant inventories. These two methods were used to identify 121 plant species, 13 of which are vulnerable species on the IUCN red list. The flora of the mature stage of Teak and Gmélina plantations resembles that of forests enriched with Fraké, which, in addition to forests enriched with Bété, are floristically similar to natural forests. Among the restored areas, the forests enriched with local species (Bété and Fraké) are richer and more diverse than the plantations with exotic species (Teak and Gmélina). Degraded forests and restoration areas harbor species that should be taken into account in the studies, as they represent an ecosystem with a wide range of species with important values for the well-being of populations. Restoring degraded areas by enrichment would be the appropriate method for a return to the original vegetation

Cavernomatose cérébrale sporadique révélée par une crise convulsive: à propos d’un cas

La cavernomatose cérébrale est une pathologie rare pouvant être sporadique ou familiale autosomique dominante. Elle est caractérisée par la présence de cavernomes multiples du système nerveux central. Souvent asymptomatique, la pathologie peut se révéler par des symptômes variés comme l’hémorragie cérébro-méningée, les céphalées ou l’épilepsie. Nous rapportons un cas de cavernomatose cérébrale sporadique chez un patient de 55 ans sans antécédent pathologique particulier révélé par une crise d’épilepsie. A travers cette observation et une revue de la littérature, nous faisons le point sur les aspects cliniques et radiologiques (scanner et IRM) de cette pathologie

Kyste colloïde obstructif du troisième ventricule avec hydrocéphalie aiguë : à propos d’un cas: Obstructive colloid cyst of the third ventricle with acute hydrocephalus: about a case

CARACTERISATION BIOCHIMIQUE ET FONCTIONNELLE DES GRAINES DE SEPT CULTIVARS DE VOANDZOU [VIGNA SUBTERRANEA (L.) VERDC. FABACEAE] CULTIVES EN CÔTE D'IVOIRE

Seeds of Bambara groundnut [Vigna subterranea (L.) Verdc.] were collected from seven cultivars in the locality of Ouangolodougou, north Côte d'Ivoire. The seeds biochemical composition was evaluated in order to determine the nutritional value of Bambara groundnut. The results showed that the moisture content varied between 7.35 to 9.02%, ash content 2.55 to 2.98 %; crude fiber 2.57 to 4.08 % and the protein content 14.61 to 20.74%. Seeds lipid composition was varying between 7.69 to 8.55 %, while the content of carbohydrate was between 54.05 to 64.50 %. Energy value was found to range from 370.02 to 388.80 Kcal per 100 g of flour. The content of phenolic compound varied from 142.43 to 205.92 mg per 100 g EG. For the functional properties, the water absorption capacity was between 199.26 to 239.75 ml per 100 g of flour, while the oil absorption capacity was between 2 to 2.12 ml / g flour. The study showed that Bambara seeds grown in that area could be a good source of nutrients. Therefore, the judicious use of Bambara seeds could be a source of additional nutrients in the diet of vulnerable population

Impact of fermentation and incorporation of cashew flour on the micronutrient and macronutrient contents of millet flour sold on the market: Case of the city of Yamoussoukro

The weaning period of an infant, which should begin from 7 months, is characterized by the gradual change from a liquid to a solid diet. After 6 months, the nutrients contained in breast milk are no longer sufficient to meet the growing demands of the infant. This is the ideal period for the introduction of a complementary food to make up for any deficiencies. To contribute to this situation, two groups, each consisting of five combinations of millet flour, enriched with cashew flour were formulated. The samples M100A0 (Unenriched millet flour), M92,5A7,5, M85A15, M77, 5A22,5 and M70A30 were enriched with 7.5%, 15%, 22,5% and 30% downgraded cashew flour, respectively. The samples MF100A0 (Unenriched fermented millet flour), MF92, 5A7,5, MF85A15, MF77, 5A22,5 and MF70A30 were constructed in a corresponding manner, the only difference being that the millet flour was fermented. After analyses of the different formulations, the best proportions of proteins were observed in MF70A30, MF77, 5A22, 5 and M70A30, which were 13.13%, 12.25% and 12.25%, respectively. Samples M70A30 and M77,5A22,5 exhibited the best iron contents of 8.44 ppm and 8.12 ppm, respectively. The protein contents of the unfortified samples M100A0 and MF100A0 were 7.53% and 6.13% respectively. Formulations MF70A30, M77,5A2,5 and M70A30 with levels of 1.06 ppm, 0.98 ppm and 0.98 ppm, respectively, gave the best zinc contents. The moisture contents of the formulated samples had minimal changes. They varied between 6.16 ± 0.06% and 7.6 ± 0.99% for unfermented samples, and between 6.35 ± 0.32% and 7.0 ± 0.02% for fermented samples. The humidity values of the two groups of samples were not significantly different at P≤0.05. These low moisture contents in the flours are important for better preservation. At the end of this study, certain formulations were selected because of their good nutritional profile. Thus the formulations M70A30 composed of 70% millet flour and 30% cashew flour and MF70A30 composed of 70% fermented millet flour and 30% cashew flour present the best options and could be used as quality infant flours

Application of multi-perspective modeling and holistic simulation to Urban Transportation Systems

International audienceAs Urban Transportation Systems (UTS) are becoming central in our daily lives, they are also gaining in complexity due to their ever-increasing interdependence with other socioeconomic dimensions (such as climate, demography and environmental policies, to name a few). This paper presents a multi-perspective modeling and holistic simulation framework that can address such a complexity. It is based on the holistic integration of models that have independently been built from the respective perspectives of various but interdependent dimensions. The resulting model can answer questions that any of the perspective-specific models cannot in isolation

Monitoring of the Sensitivity In Vivo of Plasmodium falciparum to Artemether-Lumefantrine in Mali

International audienceIn Mali, since 2007, artemether-lumefantrine has been the first choice against uncomplicated malaria. Despite its effectiveness, a rapid selection of markers of resistance to partner drugs has been documented. This work evaluated the treatment according to the World Health Organization's standard 28-day treatment method. The primary endpoint was the clinical and parasitological response corrected by a polymerase chain reaction. It was more than 99.9 percent, the proportion of patients with anemia significantly decrease compared to baseline (p < 0.001), and no serious events were recorded. Plasmodium falciparum remains sensitive to artemether-lumefantrine in Mali
