BACKGROUND Failure in detecting naturally occurring breeding sites of Aedes mosquitoes can bias the conclusions drawn from field studies, and hence, negatively affect intervention outcomes. We characterized the habitats of immature Aedes mosquitoes and explored species dynamics along a rural-to-urban gradient in a West Africa setting where yellow fever and dengue co-exist. METHODOLOGY Between...

In disaster studies, vulnerability is used to denote “the susceptibility or potential for harm to social, infrastructural, economic and ecological systems” (Pine, 2009, 136). As the nodes of critical systems of human artefacts, urban areas are vulnerable to natural hazards, and suffer losses from disasters. The vulnerability of urban areas is triggered by historical, social, political and physi...

BACKGROUND We describe trends in childhood mortality in Kenya, paying attention to the urban-rural and intra-urban differentials. METHODS We use data from the Kenya Demographic and Health Surveys (KDHS) collected between 1993 and 2008 and the Nairobi Urban Health and Demographic Surveillance System (NUHDSS) collected in two Nairobi slums between 2003 and 2010, to estimate infant mortality rat...

We explore in this paper the role of genetic variants that affect cell size and proliferation in the determination of organ size. We use genetic mosaics of loss or gain of function in six different loci, which promotes smaller or larger than normal cells, associated to either smaller or larger than normal territories. These variants have autonomous effects on patterning and growth in mutant ter...
