Sexual selection is considered the major cause of sexual dimorphism, but recent observations suggest that natural selection may play a more important role in the evolution of sex differentiation than previously recognized. Therefore, studying the trade-offs between natural selection and sexual selection is crucial to a better understanding of the ecology underlying the evolution of sexual dimorphism. The freshwater blenny , a fish inhabiting lakes and rivers around the Mediterranean Sea, displays strong sexual dimorphism in size, shape, and behavior (i.e., larger body and head size for males and higher swimming requirements for females during the reproductive period). We tested for differences in sexual dimorphism in size and shape between the populations from lake and river habitats with the goal of identifying the trade-offs between natural and sexual selection that underlie variations in sexual dimorphism in this species. Our results show i) differences in sexual size dimorphism (SSizeD) in accordance to Rensch's rule (i.e., larger individuals in rivers associated with higher SSizeD), and ii) a decrease in shape differentiation between males and females in lake populations. Together, this suggests that the different environmental conditions between lake and river habitats (e.g., resource limitations, predation pressure, water velocity) affect the relative importance of sexual selection in the display of sexual dimorphism within the species. This study highlights the importance of considering the environmental conditions to which populations are exposed to better understand the ecology underlying the evolution of sexual dimorphism.

Background: Herbal medicinal preparations are used as dietary supplements for disease prevention and as alternative/complementary medicine. The growing interest in herbal medicine raises the question of its safety and efficacy. Numerous recorded cases of intoxication and toxicological studies reveal that medicinal plants can be toxic, which hinders their safe use. Plant intoxications related to a variety of factors include plant organs and many extraction solvents. Little toxicological data on medicinal plants is available. The need to investigate is important for safe use. Imperata cylindrica, a poaceae, is one of the medicinal plants for which few toxicological data are available. Materials & Methods: To expand toxicological data, water, 70% ethanol, and 30% acetone extracts of the leaves and roots, obtained by maceration and reflux methods, were used for phytochemicals molecules qualitative detection and toxicity test by the brine shrimp lethality assay. Results: The qualitative analysis of the different extracts revealed the presence of alkaloids, polyphenolic compounds, saponins, and polyterpenoids. The toxicity endpoint was lethal concentration 50 (LC50). The leaves’ extracts LC50 was between 489.78 μg/mL and 1066.6 μg/mL. As for the root extracts, the LC50 was between 341.98 μg/mL and 1530 μg/mL. Discussion: The different compounds’ presence justifies the use of Imperata cylindrica as a medicinal plant. According to Clarkson classification the root extracts are moderately toxic (LC50: 168.47 μg/mL), and leaf extracts are weakly toxic (LC50: 527.25 μg/mL). The extrapolation made in relation to the Gosselin, Smith, and Hodge scale, allows us to characterize the Imperata cylindrica root and leaf extracts as non-toxic to humans by oral route. Conclusion: This result can be a base for more precise toxicological studies.

The response to the COVID-19 pandemic has compelled Institut Pasteur de Cote d’Ivoire (IPCI) to set up strategies for an outstanding mobilisation of human resources to fight against it. Among these strategies, we can quote the screening of people requesting COVID-19 tests at IPCI for emergency travel after the lifting of flight restrictions. Newly recruited Young researchers at IPCI, as well as Ph.D. students and trainees, were mobilised. This document describes firstly, the benefits, knowledge acquired, and difficulties encountered, and secondly, recommendations to be followed for a future large-scale epidemic. This study helped to outline some achievements, such as upgrading the talents of young researchers, strong collaboration between young researchers from different fields, and between IPCI and other institutions. The lessons learned are numerous, including mood and stress management. The difficulties encountered during this study are mainly misunderstandings, increased workload, and insufficient awareness of COVID-19 travel test procedures. These results are relevant for a possible pandemic management in our country, as well as in other African countries.

Since its outbreak in December 2019 in Wuhan Province (China), the Coronavirus (COVID-19) disease quickly spread around the world in such a way that most response plans were outdated. There was an urgent need to change and adapt response strategies as the virus globally spread. Entire firms and economies were brought to a standstill in order to reduce the virus’ capacity to spread and to limit some of the short-term impacts in order to save time and find out solutions to come back to a more or less normal way of life. Thus, most of the countries that closed their air, sea and land borders had to reopen them progressively, with travel restrictions submitted to rigid controls. In Côte d’Ivoire, as in all other countries, air travellers leaving the territory were required to provide a certificate for a negative COVID-19 test, valid for 24 to 72 hours depending on the country of destination. However, the national system implemented could not provide a result before 48 hours. The objective of this work was to develop an alternative strategy to the system for air travellers who were in a hurry and those who had a computer bug in obtaining their result. A total of 38,444 air travellers benefited from this strategy implemented by the Institut Pasteur de Côte d’Ivoire during these two years.
