Anti-inflammatory activity of a series of tri-substituted pyrimidine derivatives was predicted using two Quantitative Structure-Activity Relationship models. These relationships were developed from molecular descriptors calculated using the DFT quantum chemistry method using the B3LYP/6-31G(d,p) level of theory and molecular lipophilicity. Thus, the four descriptors which are the dipole moment μD, the energy of the highest occupied molecular orbital EHOMO, the isotropic polarizability α and the ACD/logP lipophilicity were selected for this purpose. The Multiple Linear Regression (MLR) and Artificial Neural Network (ANN) models are respectively accredited with the following statistical indicators: R2=91.28%, R2aj=89.11%, RMCE = 0.2831, R2ext=86.50% and R2=98.22%, R2aj=97.75%, RMCE = 0.1131, R2ext=98.54%. The results obtained with the artificial neural network are better than those of the multiple linear regression. However, these results show that the two models developed have very good predictive performance of anti-inflammatory activity. These two models can therefore be used to predict anti-inflammatory activity of new similar pyrimidine derivatives.

This work deals with the efficient management of industrial liquid discharges from soap factories (ILDS) in the region of Abidjan. The aim of this work is to evaluate the physico-chemical quality of these discharges as well as the different types of pollution generated. Seventeen (17) industrial soap sources were studied through fourteen (14) global pollution parameters (T, pH, electrical conductivity EC, redox potential EH, suspended matter SM, COD, BOD5, biodegradability factor BF, , , , , total iron and ). A liquid waste collection campaign was done during six weeks from February to March 2016, corresponding to a period of intensive activity of these industries. The samples were analyzed according to the norms of the French Standardization Agency (AFNOR). Results were compared with the Ivorian guide values recommended by the Classified Installations Inspection Service (CIIS). Principal Component Analysis (PCA) is allowed to evaluate the pollution induced by these factories’ rejection. In addition, Ascending Hierarchical Classification (AHC) method leads to classify soap factories into three groups according to the physico-chemical quality of their releases. Moreover, the estimation of the biodegradability factor is permitted to know the state of the biodegradability of these effluents.

Objective: To assess the perception on pharmacovigilance by the nurses and midwives at the University Teaching Hospital (CHU) of Cocody in 2017. Methodology: Descriptive and analytic cross-sectional study conducted in 17 services of the University Teaching Hospital (CHU) of Cocody using an anonymized and standardized questionnaire. Results: The response rate was 39.33% for the 86 nurses and 21 midwives with at least 10 years of professional experience (50.6%). 57.94% of the respondents (n = 62) have already heard about pharmacovigilance during their basic training (40.18%, n = 43). However, only 19.63% (21/107) of the respondents knew about the existence of a pharmacovigilance unit which they wrongly located to the pharmacy (11/21) of the CHU of Cocody. 40.18% of respondents (n = 43) had previously experienced an adverse drug reaction that was reported (76.74%, n = 33) to a hierarchical supervisor (60.60%, n = 20). The causes of non-reporting were either the frequent occurence (4/10) or the benign nature (2/10) of the adverse drug reaction. Specific actions to be taken (37.38%, n = 40) and a feedback (28.97%, n = 31) were the respondents’ main expectations for the stimulation of the reporting system. They also wanted the pharmacovigilance monitors to regularly visit their services (34.57%, n = 37) and to provide them with the reporting forms (30.84%, n = 33). Conclusion: Our study has allowed us to highlight the lack of knowledge of the pharmacovigilance and to identify certain factors that could improve the perception of the pharmacovigilance by the nurses and the midwives in Ivory Coast.

Fishponds waters intended to satisfy the nutritional needs of the populations in terms of supply of fish resources are strongly and unfortunately exposed to the mobility and dispersion of metallic trace elements (TMEs) or to the persistence in the environment and in the form of pesticide residues from human activities. The objective of this work is to evaluate, on the one hand, the levels of identified pesticide residues and, on the other hand, those of researched TMEs (lead, cadmium, mercury and arsenic) in the waters of ponds used for fish farming in Zépréguhé, a locality located 9 km from the town of Daloa in the centre-west of Côte d’Ivoire. The dosage of the samples carried out by means of a gas chromatograph coupled to a mass spectrometer (GC/MS) made it possible to detect nine (9) pesticide molecules, including eight (8) organochlorines and a single molecule from the pyrethroid family, obtained from the detection limit of 0.006 μg/L and the quantification limit of 0.018 μg/L. The maximum average concentration was obtained with α-endosulfan for a content reaching 0.8038 μg/L and well above the maximum admissible concentration of 0.1 μg/L. The TMEs were quantified using an atomic absorption spectrophotometer (AAS). Arsenic is the most abundant metal with an average concentration of 9.497 μg/L. With the exception of lead, these measured levels are above the acceptable limit values for freshwater. This study showed that human activities such as the use of fertilisers and plant protection products in plantations, sand extraction and road traffic have a negative impact on the quality of the water in ponds used for fish breeding.

Objective: To describe the growth profile of breastfeeding babies following early introduction of infant formulas to improve the feeding pattern of the young infant. Methodology: This is a longitudinal descriptive study conducted in 2 medical clinics in Abidjan from 11-Jun-2013 to 15-Dec-2016 on 100 healthy newborn babies with the introduction of infant formulas before 6 months of life. The anthropometrics parameters were compared to those of WHO. Results: The exclusive breastfeeding rate was 5%. Ablactation occurred within 12 months in 95% of cases. All Infants have doubled and tripled their birth weight at 3 and 9 months respectively. The height and the head circumference at birth increased by 50% and 37% respectively at 12 months. Compared to WHO growth charts, the weight gain for the girls at 3 months was 12.4% higher and for the boys was 7.3% higher at 6 months. On the other hands, the statural gain at 12 months was 50% lower than the WHO standards while the head circumference was 37.8% and 45.5% higher than the WHO standards in boys and girls respectively. At 3 months, the prevalence of stunting was 26.1% for boys and 13.3% for girls. Lastly, at 12 months, the BMI showed 10% overweight and 19% obesity. Conclusion: Breastfeeding associated with an early introduction of infant formulas increases the risk of malnutrition of the young infant. We advise to avoid it and recommend an exclusive breastfeeding.

Landfills are contaminated sites that need to be cleaned up to prevent human and environmental exposure to pollutants. This article aims to identify local plants capable of restoring soil polluted by heavy metals. To this end, plant species at the Bonoua landfill were inventoried. X-ray fluorescence spectrometry was used to determine the heavy metal content of soil and plants from the landfill. The bioconcentration factor (BCF) of metals in plants was evaluated. The Bonoua landfill is covered with 62 plant species, comprising 28 botanical families and 50 genera. The BCF varied from 0.08 (titanium) to 2.27 (strontium) for Phyllanthus amarus;from 0.06 (titanium) to 1.83 (copper) for Alternanthera sessilis and from 0.03 (arsenic) to 2.10 (strontium) for Amaranthus spinosus. Phyllanthus amarus, Alternanthera sessilis, and Amaranthus spinosus are strontium-accumulating species (BCF > 1). Similarly, copper BCF values were above 1 for Phyllanthus amarus, and Alternanthera sessilis. These two plant species are therefore copper accumulators. In short, Phyllanthus amarus, Alternanthera sessilis, and Amaranthus spinosus are candidate species for phytoremediation of heavy metal-polluted soils, given their BCF > 1.
