Effect of cyclodextrins on artemisinin stability and in vitro dissolution
H Zime-Diawara, F Gbaguidi, R Semde, I Some, J Quetin-Leclercq, M Moudachirou, G Piel and B Evrard
Artemisinin is extracted from the Asian plant Artemisia annua L. It has been proven to be, with its derivatives, the molecules that have shown so far the most powerful activity on malaria, even in its complicated forms and resistance cases. To resolve the problem of low aqueous solubility of this molecule, the use of cyclodextrins (CDs) was en(...)

Domain matters : bringing further evidence of the relationships among anti-patterns, application domains, and quality-related metrics in Java mobile apps.
Mario Linares Vasquez, Sam Klock, Collin McMillan, Aminata Sabane, Denys Poshyvanyk, Yann-Gael Gueheneuc
Some previous work began studying the relationship between application domains and quality, in particular through the prevalence of code and design smells (e.g., anti-patterns). Indeed, it is generally believed that the presence of these smells degrades quality but also that their prevalence varies across domains. Though anecdotal experiences(...)

Audit of cesarean delivery in Burkina Faso
Methods In a retrospective study, the medical charts were reviewed for 300 low-risk women who underwent intrapartum cesarean delivery at 10 referral hospitals in Burkina Faso between May 2009 and April 2010. In this context, cesarean deliveries were delegated to clinical officers who have less training than doctors. Results Among the 300 study(...)

La super hypertension artérielle en milieu cardiologique au Burkina Faso
N. YAMEOGO
Super hypertension is defined as systolic BP≥ 250 mmHg and/or diastolic BP≥ 150 mmHg in presence or not of complications. The aim of our study was to describe the epidemiological and evolutive patterns of super hypertension in the cardiology department of the Yalgado Ouedraogo University Hospital. It was an observation cohort over a period of(...)

Study of Antisickling and Vasorelaxant Activities and Acute Toxicity Assessment of Crude Extracts of Leaves of Ficus sycomorus L. (Moraceae)
Alphonsine Ramde-Tien, André Tibiri, Moussa Ouédraogo, Sylvin Ouedraogo ., Odile Germaine Nacou ., Innocent Pierre Guis .
The leaves of Ficus sycomorus are used in Burkina Faso folk medicine for the treatment of sickle cell disease. The present comparative study of crude extracts of leaves (decoction, macerated extract and a 95% ethanol extract) was performed with the aim to assess the efficiency of this traditional use and to determine the most active of the thr(...)

Controllability of Some Impulsive Differential Equation with Infinite delay in Banach Spaces
Issa Zabsonre
In this work, sufficient conditions for the controllability of impulsive systems with nonlocal conditions with infinite delay are established. The results are obtained by using the Schauder fixed point theorem.

Les missions chrétiennes au Sahel : une référence dans le domaine du développement
KABORE Koudbi
Dans cet article, nous avons montré la façon dont les missions chrétiennes – catholique et protestante – qui se sont implantées au Sahel à la fin des années 1950, et leurs ONG, réalisent des actions qui se déclinent sous les formes de services sociaux (santé et éducation), d’aide à l’autopromotion et au développement dans l’agriculture et l’él(...)

Multivalued problem with Robin boundary condition involving diffuse measure data and variable exponent
Stanislas Ouaro, Arouna Ouedraogo and Safimba Soma
We study a nonlinear elliptic problem with Robin type boundary condition, governed by a general Leray–Lions operator with variable exponents and diffuse Radon measure data which does not charge the sets of zero 𝑝( ⋅ )-capacity. We prove an existence and uniqueness result of a weak solution.

Physical land degradation and loss of soil fertility: soil structural stability and bio-physical indicators
Boussa Tockville Mare
This study investigates the changes in soil fertility due to the different aggregate breakdown mechanisms and it analyses their relationships in different soil-plant systems, using physical aggregates behavior and organic matter (OM) changes as indicators. Three case studies were investigated: i) an organic agricultural soil, where a combined(...)

Isolation and Characterization of hydrocarbondegrading Bacteria from Wastewaters in Ouagadougou,Burkina Faso
Sawadogo Adama, Otoidobiga C.Hamonie, Sawadogo B. Joseph, Kaboré Aminata, Traoré S. Alfred, Dianou Dayéri
Lubricants are very often found in nature under waste-oil forms and represent for the environment a real danger of pollution due to the difficulty of their biodegradation. The situation is especially worrying in most developing countries in particular those of Sub-Saharan Africa due to the absence of regulation or control. The present work aim(...)
