Le séchage est une technique utilisée pour la conservation des produits agricole. Ce travail de recherche visait à étudier le séchage des pommes de cajou préalablement trempées dans des solutions (mélasse et saccharose) osmotiques afin d’optimaliser le processus. Les expériences ont été menées à partir d’une matrice composite et le séchage s’est réalisé en suivant la méthode gravimétrique statique. Les valeurs expérimentales ont été ajustées à huit modèles empiriques à l’aide de la méthode du gradient (développée puis implémentée dans le logiciel MatlabR2016a) afin d’estimer les paramètres et coefficients. Les critères statistiques que sont le coefficient de corrélation r, l’erreur quadratique moyenne (EQM) et le χ2 ont servi à justifier le choix du modèle d’ajustement idéal. Le séchage a duré en moyenne 34 heures pour l’ensemble des échantillons trempés dans les solutions (mélasse, saccharose). Le modèle de l’approche diffusion est retenu et présente les valeurs du r (0,9822 ; 0,9986; 0,9966) les plus élevées et les plus faibles valeurs de χ2 (0,0013 ; 0,0035 et 0,0072) et EQM (0,0019 ; 0,0005 et 0,0003). Le coefficient de diffusion varie de 9,876 E-09 à 7,416 E-08 m²/s et dépend fortement de la température de séchage. L’énergie d’activation est estimée entre 18,548 – 21,430 KJ/ mol.

Drying is a technique used to preserve agricultural products. The aim of this research was to study the drying of cashew apples previously soaked in osmotic solutions (molasses and sucrose) in order to optimize the process. The experiments were conducted using a composite matrix and the drying was carried out following the static gravimetric method. The experimental values were fitted to eight empirical models using the gradient method (developed and then implemented in MatlabR2016a software) to estimate the parameters and coefficients. The statistical criteria of correlation coefficient r, root mean square error (RMSE), and χ2 were used to justify the selection of the ideal fitting model. Drying time averaged was 34 hours for all samples soaked in the solutions (molasses, sucrose). The diffusion approach model is selected and has the highest values of r (0.9822; 0.9986; 0.9966) and the lowest values of χ2 (0.0013; 0.0035 and 0.0072) and MSE (0.0019; 0.0005 and 0.0003). The diffusion coefficient varies from 9.876 E-09 to 7.416 E-08 m²/s and is strongly dependent on the drying temperature. The activation energy is estimated between 18.548 - 21.430 KJ / mol.

Mareya micrantha (Euphorbiaceae) est une plante médicinale Ivoirienne utilisée contre la diarrhée, la toux, le téniasis et aussi à des fins laxatives et abortives. L’objectif de cette étude est de déterminer les principes antibactériens contenus dans ses feuilles. Ainsi, lesfeuilles,séchées et broyées, ont été macérées dans de l’éthanol pour constituer l’extrait brut éthanolique (FE) qui après contre- extraction a conduit aux sous-extraits hexanique (FEH), chlorométhylénique (FED), acétatique (FEA), butanolique (FEB) et aqueux résiduel (FEAr). Ces différents extraits ont été évalués sur certaines bactéries responsables d’affections entériques. L’extrait brut FE et ses sous-extraits FED et FEA ne s’étaient montrés plus actifs que sur Salmonella bongori et Staphylococcus aureus (diamètres d’inhibition de 12,20 ± 0,80 à 17,10 ± 0,90 mm). Les dérivés de nor-curcubitacine (C1) et de kaempférol (C4), déterminés grâce à leurs données spectrales (SM, IR, UV, RMN 1D et 2D), sont les principes antibactériens des feuilles de la plante contre Salmonella bongori et Staphylococcus aureus. Les CMI (320 µg/mL à 730 µg/mL) et CMB (400 µg/mL à 850 µg/mL) mesurées pour ces composés montrent qu’ils exercent une action bactéricide. Ces données pourraient permettre de justifier l’utilisation en médecine traditionnelle des feuilles contre les infections entériques.

English title: Antibacterial activity and Chemical constituents from Mareya micrantha (Euphorbiaceae)
Mareya micrantha (Euphorbiaceae) is an Ivorian medicinal plant used against diarrhea, cough, tapeworm and also for laxative and abortive purposes. The aim of this study is to determine the antibacterial principles presented in its leaves. Thus, the leaves, dried and ground, were macerated in ethanol to constitute the crude ethanolic extract (FE) which after counter-extraction led to the hexane (FEH), chloromethylene (FED), ethyl acetate (FEA), butanol (FEB) and residual aqueous (FEAr) sub-extract. These different extracts were evaluated on certain bacteria responsible for enteric diseases. The FE crude extract and its FED and FEA sub-extracts were only shown to be more active on Salmonella bongori and Staphylococcus aureus (inhibition diameters from 12.20 ± 0.80 to 17.10 ± 0.90 mm). Nor- curcubitacin (C1) and kaempferol (C4) derivatives, determined using their spectral data (MS, IR, UV, 1D and 2D NMR), are the antibacterial principles of the leaves of the plant against Salmonella bongori and Staphylococcus aureus. The MICs (320 µg/mL to 730 µg/mL) and MBCs (400 µg/mL to 850 µg/mL) measured for these compounds show that they exert a bactericidal action. These data could justify the use in traditional medicine of the leaves against enteric infections.

Le changement climatique et la pression anthropique ont fortement influencé la dynamique de l’occupation des sols dans les systèmes oasiens. L’oasis de Fachi, située au cœur du désert du Ténéré au Niger, connait des changements dans l’occupation de ses sols qui impactent la mise en valeur et les caractéristiques de ces ressources. Cet article a pour objectif d’évaluer la dynamique de l’occupation des sols de l’oasis de Fachi. La méthodologie utilisée a consisté à produire les cartes d’occupations du sol pour les années 1986 et 2019 à partir des images Google Earth, des images Sentinel 2A et LandSat 8 à travers l’interprétation visuelle. Les logiciels Arcgis, QGIS et ArcMap 10.3 ont servi au traitement des données. Une mission de vérification terrain a permis de valider la carte de 2019. Les résultats révèlent qu’entre les deux dates, les superficies des palmeraies et des salines ont régressé à cause surtout de l’ensablement. Les superficies des cultures maraîchères, des sols salés et des bâtiments ont augmenté. L’ensablement et la salinisation sont les principaux moteurs de changements dans l’occupation des sols. Ces éléments constituent des véritables outils d’aide à la décision dans la gouvernance des milieux oasiens.

English title: Dynamics of land use of the oasis of Ténéré (Fachi) of the region of agadez, north eastern Niger

Climate change and anthropogenic pressure have strongly influenced the dynamics of land use in oasis systems. The oasis of Fachi, located in the heart of the Ténéré desert in Niger, is experiencing changes in land use that impact the development and characteristics of these resources. This article aims to evaluate the dynamics of land use in the oasis of Fachi. The methodology used consisted in producing land cover maps for the years 1986 and 2019 from Google Earth images and Sentinel 2A and LandSat 8 images through visual interpretation. Arcgis, QGIS and ArcMap 10.3 software were used for data processing. A verification mission validated the maps produced. The results reveal that between the two dates, the dynamics observed show that the areas of palm groves and saltworks have regressed mainly due to silting. The areas of vegetable crops, saline soils and buildings have increased. Silting and salinization are the main drivers of changes in land use. These elements constitute real decision-making tools in the governance of oasis environments.

Au Mali, les racines de Securidaca longipedunculata sont fortement utilisées et les peuplements de l’espèce se font de plus en plus rares. Ce travail visait à effectuer une étude comparative des paramètres pharmacognosiques des feuilles, écorces de tronc, écorces de racine et de la racine entière. Les échantillons ont été analysés pour déterminer les caractéristiques botaniques et physicochimiques. Des extraits aqueux et organiques ont été préparés pour caractériser les principaux constituants bioactifs par des techniques colorimétriques et chromatographiques. Les composés majoritaires ont été extraits par ultrasons et quantifiés. Les éléments botaniques communs étaient des fibres, cristaux d’oxalate de calcium, xylèmes et parenchymes. Des sclérites et fragments d’épiderme étaient seulement dans les feuilles. Le meilleur rendement d’extraction a été obtenu avec l’éthanol. Les principaux constituants étaient des tanins, flavonoïdes, coumarines, anthraquinones et saponines dans les feuilles ; des coumarines et saponines dans les écorces de tronc, écorces de racine et la racine entière. Les constituants majoritaires étaient des saponines triterpéniques dont 1,51 g de précipités enrichis ont été extraits à partir des écorces de racine. Les feuilles ont qualitativement présenté le plus de constituants bioactifs. Des investigations sont nécessaires pour évaluer leur efficacité afin de diminuer la pression sur les racines.

English title: Pharmacognostic study of the leaves, root bark, trunk bark and whole root of Securidaca longipeduncultata Fresen (Polygalaceae), harvested in Mali
In Mali, the roots of Securidaca longipedunculata are used extensively, and stands of the species are becoming increasingly are becoming increasingly rare. The aim of this work was to carry out a comparative study of the pharmacognosic parameters of leaves, trunk bark, root bark and the whole root. Samples were analyzed for botanical and physicochemical characteristics. Aqueous and organic extracts were prepared to characterize the main bioactive constituents using colorimetric and chromatographic techniques. Major compounds were ultrasonically extracted and quantified. Common botanical elements were fibers, calcium oxalate crystals, xylem and parenchyma. Sclerites and epidermal fragments were only found in leaves. The best extraction yield was obtained with ethanol. The main constituents were tannins, flavonoids, coumarins, anthraquinones and saponins in the leaves; coumarins and saponins in the trunk bark, root bark and whole root. The main constituents were triterpene saponins, of which 1.51 g of enriched precipitates were extracted from root barks. Leaves qualitatively presented the most bioactive constituents. Further investigations are needed to assess their effectiveness in reducing pressure on the roots.
Anti-oxidant, anti-microbial and anti-inflammatory activities of <i>Saba thompsonii</i> fruit extracts
Authors: Mensah John Kenneth , Thompson Philip Teye 
Published: September 2023

Aqueous extracts of the fruits of Saba thompsonii are used topically in ethnomedicine in Ghana for healthy wound healing and wound repair. The objective of this study was to comparatively assess the methanolic and the diethylether extracts of the plant phytochemicals for three bioactivities indicative of wound repairs. Using standard laboratory assays involving broth dilution, carrageenan-induced foot swelling of 7-day old chicks and DPPH radical scavenging, this study assessed the anti-microbial, anti-inflammatory and anti-oxidant activities of the methanolic and the diethylether extracts of the fruits of Saba thompsonii. Findings demonstrate that the methanolic extract of Saba thompsonii is a potent anti-inflammatory agent that suppresses carrageenan induced swelling of chick feet dose- dependently (with concentrations that ranges from 30 mg/kg through 100 mg/kg to 300 mg/kg). The methanolic extract demonstrated broad-spectrum activity against a panel of clinical isolates of bacterial and fungi pathogens in vitro (with MIC ranges of 25-100 mg/mL). Furthermore, the methanolic extract displayed a higher overall anti-oxidant status with demonstrable higher free radical scavenging action in the DPPH radical scavenging assay (IC50 of 416.8) and in the H2O2 scavenging assay (IC50 of 562.1). This methanolic extract’s enhanced bioactivity likely resulted from its higher phytochemical content relative to that of the diethylether extract. Altogether, the study supports the ethnomedicinal use of the aqueous extract of the fruits of Saba thompsonii for wound repair.

EVALUATION OF TRACHEAL ASPIRATE CULTURES IN PATIENTS FOLLOWED WITH HOME MECHANICAL VENTILATORS
Authors: AKYÜZ ÖZKAN Esra , GÜR VURAL Demet 
Published: September 2023

Introduction: In recent years, there has been an increase in the use of mechanical ventilators at home. In this study, we aimed to investigate the underlying diseases, admission complaints, microorganisms that isolated in samples taken from tracheal aspirate (TA) cultures and their resistance to antibiotics in patients followed up with mechanical ventilators at home.
Methods: Between January 1, 2020 and January 1, 2021, TA cultures, identification of bacteria and their antibiotic susceptibilities were evaluated by VITEK 2 (bioMeriux, France) automated identification system. The patients' age, gender, underlying diseases, duration of home ventilator use, complaints, and laboratory data were reviewed retrospectively from the patient files.
Results: Of the 91 prediagnosed ventilator-associated pneumonia (VAP) patients examined in the study, 72 (79%) were male and 19 (21%) were female. The ages of the patients ranged from 5 to 212 month, with a mean age of 91,64 ± 64,07 month. The most common reason for referral was fever and dyspnea and 43.76% of the patients were diagnosed with cerebral palsy/epilepsy and 10.4% with syndromes.
Of the samples; 12 (13.3%) were defined as Gram-positive and 79 (86.7%) as Gram-negative. Pseudomonas aeruginosa was detected in 44 (48.4%) samples, S. marcescens in 9 (9.9%) and Klebsiella in 8 (8.8%) samples. Staph aureus was detected in 12 (13.3%) samples. Carbapenem resistance was 18.75% for P. auriginosa, 16% for Klebsiella, 12.5 for E.coli and 12% for Acinetobacter baumani.
Conclusion: TA culture should be taken from patients with home mechanic ventilator (HMV) who admitted with signs of infection such as fever and respiratory distress and treatment should be arranged according to the result. It was observed that the TA culture antibiotic resistance rates of the patients followed up with HMV at home was lower than the TA cultures sent from the patients hospitalized in the intensive care unit.

Published: September 2023

Purpose: Many reports have revealed a high percentage of patients suffering from cognitive impairment due to COVID-19. However, data are limited at the acute phase of COVID-19. We investigated cognitive functions using the Montreal Cognitive Assessment (MoCA) in mild COVID-19 patients compared with non-COVID-19 patients within 5 days after the initial respiratory symptoms of infection.
Materıals and Methods: 113 patients with mild COVID-19 and 109 age- and sex-matched controls were enrolled in this prospective cross-sectional study. Cognitive functions were evaluated using the MoCA.
Results: We found that the MoCA scores were significantly lower in the COVID-19 patients than in the controls (P < 0.001). Compared with the controls, we found point deficits within some MoCA items such as visuospatial (P < 0.001), memory (P = 0.017), and attention (P < 0.048) domains. In the multivariate model, female sex (2.06 [1.02–4.16], P = 0.044), low education level (150.05 [5.16–43.90], P < 0.001), high fasting blood glucose level (0.98 [0.96–1.00], P = 0.043), and the presence of COVID-19 (24.24 [9.52–61.72], P < 0.001) were independently associated with cognitive impairment (OR, 95% CI).
Conclusion: We detected cognitive dysfunction, involving the visuospatial domain, memory, and attention, during the acute phase in patients with mild COVID-19.

Published: September 2023

Introduction
This study aims to evaluate the opinions of physicians in Umraniye Training and Research Hospital (UTRH), University of Health Sciences, Istanbul about modern medicine and Traditional and Complementary Medicine (T&CM).

Materials and Methods
Among the physicians working in UTRH 407 of them were interviewed. The participants were asked to complete the questionnaire prepared by the researchers. Questions evaluating their demographic information, and their opinions on modern medicine and T&CM were asked of the participants.

Results
The mean professional experience of these physicians is 10,14±9,49 years. 39.1% of the participants have received training on T&CM. 76.7% of them think that T&CM methods are useful and supportive methods for modern medicine. 74.9% of physicians think that more randomized controlled studies should be done to increase awareness about T&CM methods. The most concerning option for physicians regarding the widespread application of T&CM methods is the employment of these methods by inappropriately trained people or those who have not received any training. 85.6% (n=125) of the physicians who received training on T&CM methods think that modern medicine does not give due importance to preventive medicine. 93.8% (n=135) of the physicians who were trained in T&CM methods, preferred additional T&CM methods because the patients were not satisfied with modern medical methods, 86.6% (n=129) of them said that modern medicine has a disease-centered approach rather than a patient-centered approach.

Conclusion
Physicians think that T&CM methods are supportive and useful methods for modern medicine and state that more randomized controlled studies should be done about T&CM methods.
