RESUMEN
This paper describes the safety, efficacy and operability of the world’s first malaria vaccine (RTS, S/AS01) in latest field pilot studies and the recommendations from the WHO expert group for its use. In addition, further studies to examine the associations of inoculation rate and full-dose rate with the reduction in morbidity and mortality of malaria among target children and explore the scientific evidence for seasonable preventive vaccination with 5 doses and more among children at ages of below 5 years are recommended.
RESUMEN
La cúrcuma es una planta utilizada como condimento y colorante que posee múltiples propiedades medicinales. La evaluación de la estabilidad genética y la respuesta en condiciones de producción constituye una etapa muy importante en los sistemas de propagación de plantas por cultivo de tejidos. En este trabajo se evaluó la respuesta morfoagronómica de plantas de cúrcuma obtenidas por cultivo de tejido y por rizomas en condiciones de organopónico. Los resultados muestran una alta supervivencia (100%), para las plantas provenientes del cultivo in vitro, así como para las obtenidas a partir de los rizomas. Se logró un mayor crecimiento de las plantas propagadas por el cultivo de tejidos durante todo el ciclo de cultivo, sin cambios en las características morfológicas evaluadas. Los rendimientos en las plantas provenientes del cultivo de tejidos fueron superiores en comparación con las plantas propagadas por el método tradicional.
Turmeric is a plant uses like condiment and coloring. It has multiples medicinal properties. The genetic stability and response in production conditions is an important stage in plant propagation system by tissue culture. In this paper was evaluated the morphoagronomic response of turmeric plants obtained by tissue culture in organoponic conditions. Results show a high survival (100%) for a plant from in vitro culture as well as for the plant obtained by rizomes . A bigger growth of the plants obtained by tissue culture was observed during the whole cultured cycle without changes in the morphologycal characteristic evaluated. The yields of the plants obtained by tissue culture were higher that the plants planted by the traditional method.

Background & objectives: Insecticide incorporated plastic sheeting is a new technology to control mosquitoes in emergency shelter places and also temporary habitations in different locations. Therefore, field studies were conducted to assess the efficacy of ZeroFly® plastic sheeting treated with deltamethrin on prevailing disease vectors Anopheles culicifacies and An. fluviatilis and its impact on malaria transmission in one of the highly endemic areas of Orissa. Methods: The study was conducted in Birkera block of Sundargarh district, Orissa state. The study area comprised 3 villages, which were randomized as ZeroFly plastic sheet, untreated plastic sheet and no sheet area. ZeroFly plastic sheets and untreated plastic sheets were fixed in study and control villages respectively covering all the rooms in each household. Longitudinal studies were conducted on the bioefficacy with the help of cone bioassays, monitoring of the mosquito density through hand catch, floor sheet and exit trap collections and fortnightly domiciliary active surveillance in all the study villages. Results: In ZeroFly plastic sheeting area, there was a significant reduction of 84.7 per cent in the entry rate of total mosquitoes in comparison to pre-intervention phase. There was 56.2 per cent immediate mortality in total mosquitoes in houses with ZeroFly sheeting. The overall feeding success rate of mosquitoes in the trial village was only 12.5 per cent in comparison to 49.7 and 51.1 per cent in villages with untreated plastic sheet and no sheet respectively. There was a significant reduction of 65.0 and 70.5 per cent in malaria incidence in ZeroFly plastic sheeting area as compared to untreated plastic sheet and no sheet area respectively. Interpretation & conclusions: Our study showed that introduction of ZeroFly plastic sheets in a community-based intervention programme is operationally feasible to contain malaria especially in the high transmission difficult areas.
