| The NERICA (New Rice for Africa) rice varieties, developed by the Africa Rice Center during the 1990s, are providing hopes for raising the productivity of upland rice farmers in Africa because of their reported high yield potential and adaptability to the African conditions. The varieties are new and not widely disseminated in farming communities and there is lot of interest in the donor community in knowing their potential for widespread adoption across sub-Saharan Africa (SSA). However, when a technology is new and the target population is not universally exposed it, the observed sample adoption rate and classical models of adoption widely used in adoption studies does not inform reliably on its potential adoption and constraint to it in the full... |

| Genomic selection is an efficient approach to get shorter breeding cycles in recurrent selection programs and greater genetic gains with selection of superior individuals. Despite advances in genotyping techniques, genetic studies for polyploid species have been limited to a rough approximation of studies in diploid species. The major challenge is to distinguish the different types of heterozygotes present in polyploid populations. In this work, we evaluated different genomic prediction models applied to a recurrent selection population of 530 genotypes of Panicum maximum, an autotetraploid forage grass. We ,also investigated the effect of the allele dosage in the prediction, i.e., considering tetraploid (GS-TD) or diploid (GS-DD) allele dosage. A... |

| Background In Guinea Elapids are responsible for 20% of envenomations. The associated case fatality rate (CFR) ranged 15-27%, irrespective of treatment. Results We studied 77 neurotoxic envenomations divided in 3 groups: a set of patients that received only traditional or symptomatic treatments, and two other groups that received either 2 or 4 initial vials of Antivipmyn® Africa renewed as necessary. CFR was 27.3%, 15.4% and 17.6%, respectively. Although antivenom treatment was likely to reduce CFR, it didn’t seem to have an obvious clinical benefit for the patients, suggesting a low treatment efficacy. Mean delay to treatment or clinical stages were not significantly different between the patients who recovered and the patients who died, or between... |
