A gender-responsive breeding approach to the intensification of sesame ( L.) production in the Maradi region of Niger.

Climatic variability and a decrease in soil fertility have had a detrimental effect on the productivity of the main rainfed crops in Niger (millet, sorghum, and cowpea) and led to a deterioration of the nutritional status and income of the country's farmers. The spatio-temporal variability in rainfall has led rural populations to diversify their farms by integrating sesame ( L.) into their cropping systems because of its low water and fertilizer requirements.

[Safety and Efficacy of Artemether-Lumefantrine and Artesunate-Amodiaquine in Niger].

This study aims to evaluate the therapeutic efficacy and tolerance of two ACTs widely used for the treatment of uncomplicated malaria due to Plasmodium falciparum in Niger. The study was conducted from September to November 2017, at the Integrated Health Centers of Dogondoutchi and Birni N'Gaouré, in patients aged from 6 months to 15 years, with uncomplicated malaria due to Plasmodium falciparum. They were treated with either Artemether-Lumefantrine (AL) or Artesunate-Amodiaquine (ASAQ).

A mathematical model of malaria transmission in a periodic environment.

In this paper, we present a mathematical model of malaria transmission dynamics with age structure for the vector population and a periodic biting rate of female anopheles mosquitoes. The human population is divided into two major categories: the most vulnerable called non-immune and the least vulnerable called semi-immune. By applying the theory of uniform persistence and the Floquet theory with comparison principle, we analyse the stability of the disease-free equilibrium and the behaviour of the model when the basic reproduction ratio [Formula: see text] is greater than one or less than one.

[Intestinal parasitic infections in children in Niamey (Niger)].

Stools of 1,368 randomly selected children living in Niamey (Niger) were examined using two different parasitologic methods. One or more pathogenic parasites were recovered in 678 children (49.6%).
