Public health specialists and clinicians alike agree that Humanity faces a global pandemic of chronic diseases in the 21(st) century. In this article we discuss the implications of this pandemic on another global issue, the health workforce. Because both issues are particularly acute in Sub-Saharan Africa (SSA), we will focus on this region and use Cameroon as a case in point. We first gauge th...

Objective: Cortexin is a polypeptide extract, used in clinics for its effects on memory, attention, and brain cortical processes. A synthetic analog of one Cortexin fraction, Cortagen (i.e. Ala-Glu-Asp-Pro peptide), was developed. Both agents stimulate neural growth in vitro, presumably in association with neurotrophic factors. We assessed the psychoactive effects of Cortexin and cortagen, usin...

the response of karoun basin in lumped and semi-distributed simulation were compared. also, the flood intensity of the sub-basins and the effects of physical parameters on flood hydrograph have been investigated. results demonstrated that there was no significant difference between the characteristics of flood hydrograph in lumped and semi-distributed simulation. also, results showed that the f...

Estuaries play an important role in regulating nitrous oxide (N2O) fluxes to the atmosphere, but little is known about how catchment land-use changes influence benthic N2O cycling. We measured seasonal and constructed budgets three sub-tropical estuaries draining catchments with contrasting levels of intensity. Benthic habitats were a net sink minimally impacted Noosa River Estuary (?287 nmol m...
