An innovative one step green supercritical CO2 process for the production of liposomes co-encapsulating both a hydrophobic and a hydrophilic compound for pulmonary administration

Noémie Penoy, Kouka Luc Delma, Hermane Avohou Tonakpon, Bruno Grignard, Brigitte Evrard, Géraldine Piel

Budesonide and salbutamol-loaded liposomes were prepared using an innovative one step supercritical CO2 method without any use of organic solvents. Liposomes composed of soybean phosphatidylcholine, cholesterol and PEGylated lipid (65/30/5% (m/m)) were produced with a size less than 200 nm, a PdI within the range of 0.3 and 0.35 and encapsu(...)

Modelling factors associated with therapeutic inertia in hypertensive patients: Analysis using repeated data from a hospital registry in West Africa

Barro, Mahamadou; Yaméogo, Aristide Relwendé ; Mba, Robert Darlin ; Kaboré, Rémi; Mandi, Germain ; Dahourou, Désiré Lucien ; Zabsonré, Patrice ; Méda, Nicolas ; Goungounga, Juste

The proportion of poorly controlled hypertensives still remains high in the general African population. This is largely due to therapeutic inertia (TI), defined as the failure to intensify or modify treatment in a patient with poorly controlled blood pressure (BP). The objective of this study was to identify the determinants of TI. We conducte(...)

Energy Performances Analysis of a Solar Electric Car in Togo

Kokou Prosper Semekonawo, Sié Kam

In sub-Saharan Africa the cost of transport is very expensive for the populations. As the car fleet is mainly made up of thermal cars, the high cost of transport is largely linked to the oil’s import. Faced with such a situation, it is important to find other means of transport in order to reduce the transport’s cost for the populations. One o(...)

Experimental Study of Papaya Drying in an Indirect Solar Dryer in Natural Convection

Dianda Boureima, Traore Abdoul Fataho, Ouedraogo Adama, KY Sikoudouin Maurice Thierry, Ouedraogo Issaka, Kam Sié, athiébo Dieudonné

Papaya is a fruit that is prized for its flavor and also for its different appearances. It is seasonal and easily perishable in our climatic conditions. This work is devoted to the improvement of conservation techniques such as drying. We conducted our experimental work in an indirect solar dryer in natural convection under(...)

Production des violences et contre-violences dans les ménages à Ouagadougou

BACYE Yisso Fidèle; ZANGRE/KONSEIGA Kiss-Wend-Sida Romaine

Les rapports humains sont des rapports de domination. Les ménages mettent en relation des interrelations entre époux et épouses laissant apparaître des échanges non marchands. Les interactions étant l’assise des rapports de force, produisent des conflits d’affirmation, d’expression des sentiments, de lutte d’espace et de marges sociales. D(...)

Characterizing sorghum (Sorghum bicolor [L.] Moench) varieties diversity to identify those with contrasting traits of interest for intercropping systems in the Sudano-Sahelian zone of West Africa

Ganeme A, Kondombo CP, Raboin L-M, Dusserre J, Kabore R, Adam M, Traoré S

Sorghum is an important staple crop in Sub-Saharan Africa. In the Sudano-Sahelian zone of West Africa, sorghum is mainly intercropped with cowpea, but these intercropping systems are facing low-productivity problems. The overall aim of this research was to identify sorghum varieties with different agro-morphological and physiological traits(...)

Article Acetobacter senegalensis isolated from mango fruits: Its polyphasic characterization and adaptation to protect against stressors in the industrial production of vinegar: A review

Bassirou NDOYE Rasoul Shafiei Nastaran Shah Sanaei Ilse Cleenwerck Marius SOMDA Lat Souk Tounkara Amadou T. GUIRO Frank Delvigne Mamoudou H. DICKO, Prof. Philippe THONART

It has been more than a decade since Acetobacter senegalensis was isolated, identified and described as a thermotolerant strain of acetic acid bacteria. It was isolated from mango fruits in Senegal and used for industrial vinegar production in developing countries, mainly in sub-Saharan Africa. The strain was tested during several spirit(...)
