Prevalence and mitigation of aflatoxins in Kenya (1960-to date) por Mutegi, C., Cotty, P.J., Bandyopadhyay, Ranajit

“…These include: sparse documented information on human exposure; few robust tools to accurately measure economic impact in widely unstructured value chains; lack of long-term impact studies on benefits of aflatoxins mitigation; inadequate sampling mechanisms in smallholder farms and grain holding stores/containers; overlooking social learning networks in technology uptake and lack of in-depth studies on an array of aflatoxins control measures followed in households. …”

iMap: a databasedriven utility to integrate and access the genetic and physical maps of maize por Fang, Z., Cone, K., Sánchez Villeda, H., Polacco, M., McMullen, M., Schroeder, S., Gardiner, J., Davis, G., Havermann, S., Yim, Y., Vroh Bi, Irie, Coe, E., Bi, I.V.

“…To display this integrated map, we have developed iMap. iMap has three main components: a relational database (iMapDB), a map graphic browser (iMap Viewer) and a search utility (iMap Search). iMapDB is populated with current genetic and physical map data, describing relationships among genetic loci, molecular markers and bacterial artificial chromosome (BAC) contigs. The database also contains integrated information produced by applying a set of anchoring rules to assign BAC contigs to specific locations on the genetic map. …”
