Malaria is a major health problem, with over one third of Background worldwide populations currently at risk. Determining the genetic diversity of plasmodium parasites is essential for assessing the efficacy of antimalarial drugs and for future vaccine development. This study investigated the genetic diversity of merozoite surface protein 2 (MSP2), and multiplicity of P. falciparum infection ...

River basins as diverse as the Nile, the Amazon, and the Mississippi satisfy certain topological invariants known as Horton’s laws. Do these macroscopic (up to 103 km) laws extend to the micron scale? Through realistic simulations, we analyze the morphology and statistical properties of networks of vortex flow in flux-gradient-driven superconductors. We derive a phase diagram of the different n...

Rapid land use change due to intensive agricultural practices in the Ethiopian Highlands, results in increasing rates of soil erosion. This manifested in significant impacts downstream by reducing the storage capacity of reservoirs (e.g., Roseires, Sennar), and high desilting costs of irrigation canals. Therefore, this paper aims to provide a better understanding of the process at basin scale. ...

The use of biomarkers has become an important tool for modern environmental assessment as they can help to predict pollutants involved in the monitoring program. Here I present data on bioaccumulation, biochemical and tissues biomarkers in Nile tilapia as early warning indicators of river Nile pollution. Nile tilapia sampled from downstream sites accumulated higher levels of all the detected he...

Due to increasing water use, diversion and salinization, along with subsidence sea-level rise, deltas in arid regions are shrinking worldwide. Some of the most ecologically important include Colorado, Indus, Nile, Tigris-Euphrates. The primary stressors vary globally, but these threatened by increased storage diversion, eutrophication, wetland loss. In order make sustainable over time, some flo...

The present study was carried out to investigate the adsorption and leaching behavior of Cu2+, Zn2+ and Pb2+ by sediments collected from the western banks of three different sectors along River Nile at Aswan governorate, Egypt. The feasibility of sediments for the removal of Cu2+, Zn2+ and Pb2+ from aqueous solutions was tested under the effect of three conditions (pH, initial metal concentrati...

West Nile virus (WNV) is an arthropod-borne Flavivirus usually transmitted to wild birds by Culex mosquitoes. Humans and horses are susceptible to WNV but are dead-end hosts. WNV is endemic in Senegal, particularly in the Senegal River Delta. To assess transmission patterns and potential vectors, entomological and sentinel serological was done in Ross Bethio along the River Senegal. Three senti...
