Objective: To examine the effect of combination of Andrographis paniculata herb fraction(AHF) and Centella asiatica herb fraction(CHF) on PPAR γ and GLUT4 mRNA expression in 3 T3-L1 adipocyte, and its effect on insulin-stimulated glucose uptake. Methods: 3 T3 L1 adipocyte cells were used to investigate gene expression of PPARy reverse transcription-polymerase chain reaction method. The γ and GLUT4 protein b adipocyte cells were differentiated by using insulin, dexamethasone and 3-isobutyl-1-methylxanthine from 3 T3-L1 cells. Pioglitazone, AHF, CHF and the combination of both herbs were evaluated on glucose uptake activity, PPAR γ and GLUT4 mRNA expressions in 3 T3-L1 adipocyte. Results: The results showed that combination of AHF at 30 μg/mL and CHF at 10 μg/mL could enhance insulin-stimulated glucose uptake. The combination also increased PPAR γ and GLUT4 mR NA expressions significantly in comparison to those of negative control(DMSO). These effects were equal in comparison to those of pioglitazone(0.02 μM) and its single extracts Conclusions: The combination of AHF and CHF can increase glucose uptake and insulin sensitivity through up-regulation of PPAR γ and GLUT4 mRNA expressions in 3 T3-L1 adipocyte.

Aim: To determine the prevalence of re-hospitalization for heart failure in the cardiology unit of the Yaoundé General Hospital. Study Design: This was a retrospective cross-sectional study from January 2015 to December 2020. Patients and Methods: Patients aged at least 18 years who were hospitalized for heart failure during the study period were included. Data were collected using a predesigned form and were analyzed using Epi InfoTM version 7.2.2. Results: We included a total of 160 patients. The prevalence of re-hospitalization was 30.6%. Re-hospitalized patients had a mean age of 71.0 ± 13.9 years and a sex ratio of 1.6. The most common etiologies of HF were hypertensive heart disease (36.7%), followed by dilated cardiomyopathy (22.5%), and atrial fibrillation (16.3%). More than two third had class IV NYHA disease (77.6%). Most of them also had HFrEF (71.4%) and anemia (77.6%). Conclusion: There is a high rate of re-hospitalization in the cardiology unit of the Yaoundé General Hospital with most of these patients having old age and severe HF.

This research work is related to soliton solutions considered as models that can describe the complex configuration of elementary particles from the study of the interactions of their fields. It is interested in the interaction of fields between two different elementary particles by expressing their physical properties. For that, we have obtained, exact static plane symmetric soliton-like solutions to the nonlinear equations of interacting electromagnetic and scalar fields taking into account the own gravitational field of elementary particles using the calibrated invariance function P(I). It has been proved that all solutions of the Einstein, nonlinear electromagnetic and scalar field equations are regular with the localized energy density. Moreover, the total charge of particles is finite and the total energy of the interaction fields is bounded. It have been emphasized the importance to the own gravitational field of elementary particles and the role of the nonlinearity of fields in the determination of these solutions. In flat space-time, soliton-like solutions exist but the total energy of the interaction fields is equal to zero. We have also shown that in the linear case, soliton-like solutions are absent.

In this paper, we have used the static spherical symmetric metric. The parameter of the nonlinearity fields is included in the arbitrary function characterizing the interaction between the electromagnetic and scalar fields. Taking into account the own gravitational field of elementary particles, we have obtained exact static spherical symmetric solutions to the electromagnetic and scalar field equations of nonlinear induction. Considering all forms of the solution of Liouville equation, we proved that the metric functions are regular with localized energy density. Moreover, the total energy of the nonlinear induction fields is bounded and the total charge of the elementary particles has a finite value (soliton-like). In the flat space-time, soliton-like solutions exist.

The purpose of this study is to assess the physical and chemical quality of borehole water intended for consumption in the collines department in Benin. At the end of a sampling campaign, twenty-one (21) drinking water points were sampled. Different physico-chemical parameters were measured using standard analysis methods. The results of the analysis of the samples, showed that the groundwater of the department of the hills is characterized by a neutral pH and an average electrical conductivity in accordance with the WHO and Benin standard relating to the potability of groundwater. With this pH neutrality which would be linked to the nature of geological formations made up of crystalline rocks, the water in the hills is moderately hard with hardness values of 208 mg/L on average for magnesium ions of 22.54 mg/L on average and calcium ions of the order of 46.03 mg/L on average at the scale of the various localities and an alkalinity is of 43.81 mg/L on average. The values between 0 and 163.91 mg/L are low in the South-East and very high, even exceeding the standard accepted by WHO in the West and North-East of the study area. This nitrate pollution and the fairly high levels of organic matter in total nitrogen observed in the groundwater of the hills could also have an impact on the vulnerability of the water table. And this pollution with nitrates associated with electrical conductivity and chloride levels modifies and degrades from one drinking water point to another the potability of underground water in the hills.

The purpose of this study is to assess the state of contamination of fish in the S? River by trace metal elements including Zinc, Lead, Cadmium, Copper and Arsenic. Water samples and four species of both sexes (Clarias anguillaris, Kribia kribensis, Tilapia guineensis and Eleotris vittata) were collected and analyzed. The pH, temperature and values of the chemical species present in the water of the S? River characterize an ecosystem favorable to the growth of aquatic species. The Metallic Traces Elements (MTE) concentrations vary from one fish species to another and depend on the sex and age of the animal. Zinc and copper are more concentrated in males than females with the exception of copper in Tilapia. The Pb concentration is higher in young Kribia and Clarias as well as Zn and Cd in young Tilapia. The concentrations in Cd and Pb are well above the European standards and those in the Republic of Benin, worrying results that express a health toxicity risk related to the consumption of fish of the river S?.
