Physicochemical investigations were performed on seeds of Nymphea lotus and N. micrantha consumed in the Senegal River valley. They revealed a composition similar to that of cereals. In order to estimate their intrinsic quality, the determination of their amino acid, fatty acid and monosaccharids profiles was done. The results indicate that monosaccharides are represented specifically by saccharose (7%) and glucose (0.67%);a predominance of stearic acid and linoleic acid as unsaturated acids (24.86%);arachidic and palmitic acids as the only saturated acid found (11.12%);a good ratio of unsaturated/saturated acid (2.23);a lack of oleic acid, linoleic, palmitoleic, myristic, caprylic acids;a poor-quality index protein due to low quantity amino acids. Nevertheless, all essential amino acids are present in the seeds. The Nymphea sp grains consumed by the populations around the Senegal River valley offer an interesting nutritional quality linked to fatty acids and carbohydrates.

Hydrogeochemical characterization of Groundwater from Fissured Aquifers in the Angovia Mine Operating Permit Area (central-West côte d’Ivoire)

引用

Journal of Water Resource and Protection 2024年第1期16卷 83-101页

作者： Kouadio michel Yao Tanina Drissa Soro Tanoh Jean Jacques Koua Akaie Jean Fabrice Tchakray Yao Emile Desmond Konan Brou Dibi Laboratory of Sciences and Technologies of Environment University Jean Lorougnon Guede Daloa C&ocircte d’Ivoire

The main objective of this study is to determine the hydrogeochemical specificities of the groundwater of the Angovia mine operating permit, located in the Yaouré mountains in the center-west of côte d’Ivoire. To do so, descriptive and multivariate statistical analysis methods with the SOM (Self Organizing Maps) algorithm were applied to the physicochemical parameters of 17 boreholes using the calcite (ISc) and dolomite (ISD) saturation indices. The results obtained have shown that the groundwater in the Angovia mine operating permit area has an average temperature of 27.52°c (long rainy season) and 27.87°c (long dry season) and has an average pH of 7.09 ± 0.35 during the main rainy season and 7.32 ± 0.35 during the main dry season. They are mineralized with an average electrical conductivity of 505.98 ± 302.85 μS/cm during the long rainy season and with 450.33 ± 233.74 μS/cm as average during the long dry season. The main phenomena at the origin of groundwater mineralization are water residence time, oxidation-reduction and surface inflow. The study of the relative age of the water shows that the groundwater in the Angovia mine operating permit area is mainly undersaturated with respect to calcite and dolomite. They are therefore very old in the aquifer with a slow circulation speed during the long rainy season and the long dry season.

Open Journal of Orthopedics 2024年第9期14卷 381-390页

作者： Loukou Blaise Yao Koffi Léopold Krah Aya Adelaïde Natacha Kouassi Kouamé Innocent M’bra Kouamé Jean-Eric Kouassi michel Kodo Department of Trauma and Orthopaedics Bouak Teaching Hospital Bouak Cte dIvoire

Background: Surgical site infections are serious healthcare problems. The aim was to describe the epidemiological, diagnostic, therapeutic, and prognostic aspects of surgical site infections in Trauma and Orthopaedics at Bouaké Teaching Hospital. Method: This retrospective, descriptive, and analytical study was conducted from January 2019 to December 31, 2021. The data studied included prevalence, initial lesions, type of surgical intervention, type of SSI, bacteria involved, treatment, and outcomes. Results: Forty-four (11%) of the 399 patients included in the study developed a surgical site infection. The mean age was 27 years, with 36 male and 8 female. Initial lesions were predominantly open fractures (n = 31;70%), with a mean delay of 48 hours for surgical management. Emergency interventions accounted for 70% (n = 31) of cases. The NNISS infection risk score was 1 in 80% (n = 35) of cases. Superficial infections (n = 34;77%) appeared early, on a mean 6 days postoperatively. Bacteriological analysis primarily identified Pseudomonas aeruginosa (n = 10;23%), sensitive to Imipenem and chloramphenicol but resistant to Amoxicillin-clavulanic acid, ceftriaxone, Gentamicin, and ciprofloxacin. Multidrug-resistant bacteria were found in 89% (n = 8) of cases, with all bacteria resistant to ceftriaxone. Surgical revision was performed in 10 patients (23%), primarily involving debridement with hardware retention (n = 7;70%). chloramphenicol was the most commonly used antibiotic post-antibiogram (61%). Outcomes were favourable in 98% of cases. Identified risk factors included the type of lesion according to NRc classification, the delay in managing open fractures, and the NNISS score. conclusion: The prevalence of surgical site infection was 11%, favoured by the delayed operation of open fractures.

Using Optical Tweezers to Study the Friction of the Red Blood cells

In the last two decades the study of red blood cell elasticity using optical tweezers has known a rise appearing in the scientific research with regard to the various works carried out. Despite the various work done, no study has been done so far to study the influence of friction on the red blood cell indentation response using optical tweezers. In this study, we have developed a new approach to determine the coefficient of friction as well as the frictional forces of the red blood cell. This approach therefore allowed us to simultaneously carry out the indentation and traction test, which allowed us to extract the interfacial properties of the microbead red blood cell couple, among other things, the friction coefficient. This property would be extremely important to investigate the survival and mechanical features of cells, which will be of great physiological and pathological significance. But taking into account the hypothesis of friction as defined by the isotropic coulomb law. The experiment performed for this purpose is the Brinell Hardness Test (DB).

Background and Objective: Hepatocellular carcinoma (Hcc) is a public health problem due to its high incidence and high mortality rate. The epidemiology and prognosis of this disease is poorly documented in Bouake. The aim of the study was to describe the epidemiological aspects and identify the predictors of death in patients hospitalized for Hcc in the Internal Medicine Department of the Bouake University Hospital in order to improve patient management. Material and Methods: We conducted a cross-sectional study from 1 January 2020 to 31 December 2022 in the Internal Medicine Department of Bouake University Hospital, involving 160 patients. Results: The prevalence of Hcc was 3.6%, the mean age was 48.86 ± 14.5 years with extremes of 14 and 90 years and the sex ratio was 2.90. Viral hepatitis B was observed in 81% of patients, with HBs Ag positivity in 71.2%. The performance status of WHO was ≥ 2 in 93.2% of cases. Hcc was discovered at advanced stage respectively in 51% for BcLc c and 47.8% for BcLc D stage. The nodules were multiple (89.3%), and superior to 3 cm. The hospital mortality was 20% and BcLc D stage of Hcc was significantly associated with death (p = 0.04) in the univariate analysis. The BcLc D stage of Hcc was significantly associated with death. Length of stay inferior to 5 days (OR = 0.77;cI 95: 0.61 - 0.96) and hepatic encephalopathy (OR = 1.39;cI 95: 1.10 - 1.77), were the two independent predictors of mortality. conclusion: Hcc mainly affected young men infected with chronic viral hepatitis B. Short length of stay and hepatic encephalopathy were independent predictors of mortality.
