This study aimed to evaluate the qualitative phytochemical profile of the hydroethanolic extract of Annona senegalensis leaves and to validate its biological properties. High-performance thin-layer chromatography (HPTLC) analysis, quantification of phytochemical compounds, followed by in vivo evaluation of antioxidant, analgesic and neuroprotective activities were performed using standardized methods. HPTLC analysis revealed a rich profile of phenolic and terpenic compounds, with rutin and quercitrin identified as prominent constituents and further confirmed by spectrophotometric quantification. The confirmed phytochemical profile is closely correlated with in vitro antioxidant properties (IC50 of 27.81 ± 2.35 µg/mL) and significant inhibition of lipid peroxidation (70.84 ± 2.06%). The extract was well tolerated and showed anxiolytic and analgesic effects without producing sedation. The...

Background Access to Family Planning (FP) services remains limited in many low-income countries, particularly in Burkina Faso. Understanding the availability, readiness, and geographic accessibility of contraceptive services is essential to improve delivery and utilization. Methods We conducted a secondary data analysis from two databases linked using geospatial information. The Harmonized Health Facility Assessment (HHFA) facility census was performed in 3,056 health facilities in Burkina Faso. A nationally representative female population-based survey was also conducted with 6,947 women in reproductive age by the Performance Monitoring for Action (PMA). The indicators on FP services included the offering, the provision of short- and long-acting methods, the availability and the accessibility to the facility offering any contraceptive method. Women were linked to the nearest health fac...

Agroecological innovation can support vegetable farmers in responding to climate change and market instability, yet such innovations remain insufficiently documented, limiting their wider adoption. This study analysed agroecological innovations observed on vegetable farms in Burkina Faso with the aim of supporting their scaling up. Semi-structured interviews were conducted with 75 participants, comprising 67 producers and 8 key informants selected through purposive sampling. Data collection focused on changes in agroecological vegetable-farming activities, including production, resource management, and marketing. Thematic analysis was used to identify innovations, assess their adoption rates by locality, and establish a typology according to their intrinsic nature and intensity. A total of 32 innovations were identified across several activity areas. Adoption varied among localities in r...

Cet article développe et fait la validation de premier niveau d'une échelle d'orientation des néo-bacheliers et des étudiants. La première étape d'élaboration des items s'inspire de l'échelle originale des ancres de carrière de E. H. Schein (1978 ; 1990) dont l'adaptation, l'examen et la contextualisation par un comité d’experts et des étudiants et le prétest ont permis d'assurer une validité de contenu de ce nouvel outil. En s'appuyant sur les trois premières étapes de ce processus à travers l’élaboration d’une liste préliminaire d’items, leur examen et réduction par des enseignants experts (N = 02) et des étudiants (N = 31), ainsi que leur prétest cognitif avec trois groupes de discussion, cela a permis de renforcer la validité de contenu de l’échelle. L’analyse des données quantitatives recueillies auprès d’un échantillon de 345 néo-bacheliers issus de différentes localités du Burkina...

This article develops a compartmental mathematical model to investigate the impact of excessive social media use on the academic performance of higher education students. Students who are heavily subscribed are classified ‘infected or addicted’ individuals. Their influence on the other naive non-subscribers leading them to become one and by self-curiosity are defined as direct and indirect transmission routes, respectively. The model incorporates two primary control interventions: early awareness programs and continuous regulation of accessibility. Qualitative and numerical analyses of the model dynamics are thus carried out investigating the effectiveness and the benefits of these control measures. The results suggest that a combined strategy, implementing both control interventions at optimal efficacy levels, significantly reduces the ‘addiction’ rate, thereby fostering a healthier aca...

The leaves of Capparis sepiaria and Maerua angolensis are consumed by some populations in Burkina Faso and are traditionally associated with gastrointestinal uses. This study evaluated the anti-ulcer and analgesic activities of aqueous leaf extracts of both plants in mice. Gastroprotective activity was assessed using ethanol-induced gastric ulcer models under acute and chronic conditions, while analgesic activity was evaluated using acetic acid-induced abdominal contortions. In the acute model, Capparis sepiaria extract at 500 mg/kg produced 92% protection of the gastric mucosa, compared with 96% for sucralfate. The ulcer index decreased from 10 at 300 mg/kg to 4.83 at 500 mg/kg for Capparis sepiaria. In the chronic model, the ulcer index decreased from 0.83 in the ulcer control to 0.08 with selected extract treatments, and extracts of both plants showed a better healing of ulcer lesions...

Introduction : La prééclampsie constitue dans le monde un véritable problème de santé tant dans sa fréquence, la diversité de sa prise en charge que dans ses complications. Objectif : il s’est agi d’étudier la prééclampsie sévère dans le département de gynécologie et de médecine de la reproduction du centre hospitalier universitaire Sourô Sanou. Méthodologie : nous avons réalisé une étude transversale à visée descriptive avec recueil rétrospectif des données sur une période d’un an allant du 1er Janvier au 31 Décembre 2019. Ont été incluses dans l’étude 171gestantes admises dans le département et porteuses d’une grossesse au terme de 20 semaines d’aménorrhée (SA) ou plus et chez qui le diagnostic de prééclampsie sévère a été posé au cours de la grossesse, ou du travail d’accouchement. Les données recueillies ont été saisies sur un micro-ordinateur et analysées avec le logiciel EPI inf...

Title: Review of 18 months of activities in the medical-surgical emergency department of the Ziniare Regional Hospital Center Introduction: By ensuring early detection of acute illnesses and timely access to necessary care, organized emergency care systems save lives and amplify the impact of many other components of the health system.

Jute mallow is a leafy vegetable cultivated in urban and peri-urban farming systems in Burkina Faso. This research aims to select high-yielding and stable Jute mallow genotypes through evaluation in three locations. To do this, 20 genotypes were tested at three locations across Burkina Faso. The agronomic data were subjected to two-way analysis of variance and Genotype plus Genotype by Environment (GGE) biplot analysis using R software. The results revealed highly significant (p < 0.01) differences among genotypes for all agronomic traits. In addition, highly significant genotype × environment (GEN × ENV) interactions were observed for all traits. Comparative analysis of the average performance of the genotypes studied showed that plant heights ranged from 78.708 to 134.556 cm for genotypes AZIGA and HBV9. Regarding plant height (134.556 cm), stem diameter (15.181 mm), and number of bran...

This study addresses the insufficient understanding of the impact of high-voltage (HV) transmission line electric fields on photovoltaic (PV) conversion mechanisms, a critical issue for the deployment of PV systems in constrained land-use environments. Using a theoretical framework based on semiconductor physics and the Charge Simulation Method (CSM), we analyze the influence of external electric fields on the individual conversion processes of a polycrystalline silicon solar cell. Results show that the electric field enhances carrier kinetic energy, leading to increased current but reduced voltage near the HV line. A non-linear behavior of overall efficiency is observed, with a maximum at approximately 85m from a 225kV line. This work identifies an optimal installation zone (80-100m) and provides new insight into the coupling between external electric fields and PV conversion processes....
