1. Abstract 1.1. Introduction A major hepatectomy is defined as the resection of at least three liver segments. Most often carried out as part of the treatment of a malignant liver tumor, it still causes significant morbidity and mortality. 1.2. Objective To report the morbidity and survival of patients who underwent major hepatectomy in the hepatobiliary surgery unit of the Ten- gandogo University Hospital Center. 1.3. Methods A retrospective study was conducted over 83 months. Data of in- terest including patient epidemiology, diagnostics, type of surgery, postoperative outcomes and prognostic factors were studied. 1.4. Results Major hepatectomies were carried out in 38 patients, 27 of whom were male. There was an annual average of 4.75 major hepatec- tomies, representing 64.4% of liver resections performed. Major hepatectomy was performed in 28 patients (73.6%) for hepato- cel...

The construction of multivariate distributions with arbitrary margins has been a problem of interest to statisticians for many years, but nowadays, by virtue of Sklar’s theorem, this problem can be reduced to the construction of a copula. However, there is no general method for constructing a copula. In order to provide a partial solution to this problem, we present in this article, a construction of a new class of ratio-type copulas called a class of copulas with horizontal or vertical section of a homographic function. Indeed, the horizontal section of the copulas of this class can be considered as a homographic function of variable u whose coefficients are functions of v (formula (8)) and the vertical section can be considered as a homographic function of variable v whose coefficients are functions of u (formula (9)). This class can be also considered as a generalization of Ali-Mikhai...

In Burkina Faso, products and nests of insect are used for therapeutic purposes in traditional medicine. However, this use by local populations is marginal and empirical. The objective of this study was to evaluate the antimicrobial activity of extracts of bees’ products and termite nests. Thus, the collected termite nests were finely ground. Hydroethanolic extraction of bioactive molecules with potential antibacterial activity was performed according to standard methods. The agar diffusion method was used to test the antibacterial activity of hydroethanolic extracts of honey bee, bee wax, propolis, and termite nests against 22 pathogenic strains by inhibition diameter. Imipenem and nystatin were used as a positive control for bacterial and fungal strains respectively. The extraction yields varied from 7.33 to 35.39% depending on the content of soluble matter. All extracts of bees’ prod...

In this work, we consider a system of stochastic integrodifferential equations in a complex Hilbert space. We first establish the existence and uniqueness of mild solutions for equation (1) under non-Lipschitz conditions. Then we show under certain assumptions that the found mild solution is exponentially stable on average of order n. Note that the same equation was studied in [10] where the authors found the solution in a real Hilbert space. We now provide a generalization of this result in a complex Hilbert space. We obtain existence and uniqueness results by using the Lipschitz global and growth conditions

Zanthoxylum zanthoxyloides, a medicinal plant overexploited in Burkina Faso due to the use of its roots for therapeutic purposes has been studied and it seems that the profile of the powder from stem and root bark are almost similar. This study aims to compare the botanical, physicochemical, and phytochemical parameters of Z. zanthoxyloides powder from stem and root bark for rational use. Botanical characters were carried out while methanol and water extraction yield, residual moisture, total ash, and insoluble ash in chlorohydric acid were estimated. Phytochemical screening was realized by the HPTLC using a THF-toluene-formic acidwater (59:30:7:4, v /v/v/v) solvent system. The total phenol and flavonoid content of both methanolic and aqueous extracts were quantified and their antioxidant activities were assessed using the ferric ion-reducing power and DPPH methods. Important fibers were...

While Bambara groundnut (Vigna subterranea (L.) Verdc.) originates from Africa and the list of producers is topped by African countries, it is not clear whether research is developed enough to support crop promotion in the continent. Thus, this systematic review of 180 articles presents a comprehensive summary of research on Bambara groundnut (BGN) in Africa. The paper addresses bibliographical metrics, the geographic distribution of the research and themes covered (viz., food and nutrition security, climate resilience, and livelihoods). The analysis shows that BGN can help address different challenges in Africa, such as food and nutrition insecurity and poverty. However, it also highlights gaps in the research from geographical and thematic standpoints. Geographically speaking, the most important producers of BGN in Africa are not sufficiently covered in the research; instead, it is ma...

Extract at 10 mg/mL yielded 92.95±11.44 mg EAG/g total polyphenols, 0.082±0.005 mg ERu/g total flavonoids and 0.14 ± 0.003 mg EAT/g condensed tannins. Aqueous extract of Sarcocephalus latifolius ripe fruits showed DPPH radical inhibition with an IC50 greater than 25 μg/mL. DPPH inhibition by gallic acid was 92.91% at 25 μg/mL. IC50 of ascorbic acid and aqueous extract of Sarcocephalus latifolius on Fe3+reducing antioxidant power (FRAP) were 18.9 μg/mL and 111.6 μg/mL, respectively. For carrageenan, the aqueous extract of Sarcocephalus latifolius ripe fruits showed a maximal anti-inflammatory effect at five hours, with inhibitions (p

Introduction: A caudal appendix is a rare congenital malformation of the median or paramedian diverticulum type located mainly in the lumbosacral region, of soft consistency, exceptionally provided with an axial skeleton and covered with skin often of normal appearance and simulating a tail. Patients: We report the cases of three female patients including two infants aged 4 months and 12 months and an adult aged 35 years. The infants presented caudal appendages located at the atypical breech surface associated with a right cephalocele and the adults had a caudal appendage 11 cm long located at the lumbosacral level 2 cm from the midline on the right. Clinical examination noted one lesion in the first infant and three caudal appendages in the second. The neurological examination was normal. The adult patient did not present any associated clinical malformation. The CT scan...

L'adolescence et la jeunesse, périodes de recherche identitaire, expose souvent à des expériences risquées, telles que la pratique de la chicha de plus en plus populaire à Ouagadougou au Burkina Faso, si bien qu’une réglementation récente a interdit sa consommation dans cette ville soulevant ainsi des interrogations sur ses déterminants. La présente investigation analyse alors les déterminants de sa consommation chez les adolescents et les jeunes dans cette ville. Ainsi, l'échantillonnage s'est basé sur un plan de sondage stratifié, avec des enquêtes qualitatives et quantitatives. Les résultats indiquent une prévalence significative de la consommation de chicha chez les adolescents et les jeunes, influencée par des facteurs socio-culturels et économiques. La facilité d'accès et le coût abordable de la chicha contribuent à sa popularité, avec une forte présence dans les maquis et les bars...

The Sahel is a region particularly characterized by undernutrition in several forms. In Burkina Faso, where several interventions have been carried out across the past several years, the nutritional situation of children under five years of age is still charac-terized by persistent stunting in the Est, Sahel, and Cascades regions. This study aims to understand the factors associated with the high prevalence of chronic malnutrition in these regions. National nutrition survey data as well as data from the Ministry of Water and Sanitation were used for bivariate and multivariate statistical analyses to identify factors statistically associated with stunting in children aged 0-59 months who participated in the national nutritional surveys from 2009 to 2019. Around one in ten mothers in all regions had no schooling at all. The improving of IYCF practice has a positive impact on the reduction...
