On the interest of ambipolar materials for gas sensing
Based on the electrochemical properties of a series of metallophthalocyanines this article shows that the phthalocyanine bearing four alkoxy groups and twelve fluorine atoms behaves approximately as those with eight fluorine atoms. This indicates that the electron-donating effect of one alkoxy group balances the electro-withdrawing effect of o(...)

Regulation of the Na+‐K+(NH)‐2Cl− cotransporter of rat submandibular glands
E. KABRE
A cellular suspension from rat submandibular glands was exposed to different concentrations of NH4Cl, and the variations of the intracellular concentration of calcium ([Ca2+] i) and the intracellular pH (pHi) were measured using fura‐2 and 2′, 7′‐bis‐(2‐carboxy‐ethyl)‐5 (6)‐carboxyfluorescein. More than 5 mmol/l NH4Cl significantly increased t(...)

The kdr-bearing haplotype and susceptibility to Plasmodium falciparum in Anopheles gambiae: genetic correlation and functional testing
A. GNEME
Members of the Anopheles gambiae species complex are primary vectors of human malaria in Africa. It is known that a large haplotype shared between An. gambiae and Anopheles coluzzii by introgression carries point mutations of the voltage-gated sodium channel gene para, including the L1014F kdr mutation associated with insensitivity to pyrethro(...)

Floristic and dendrometric analysis of woodlands in the Sudano-Guinean zone: a case study of Belléfoungou forest reserve in Benin
A. OUEDRAOGO
A floristic and dendrometric analysis was carried out using 15 square plots of 1 ha each in the Belléfoungou forest reserve, located in the Sudano-Guinean zone of Benin. Species and diameter at breast height of trees were recorded. Multidimensional scaling and importance value index of species were used to identify vegetation types in the rese(...)

Three years of insecticide resistance monitoring in Anopheles gambiae in Burkina Faso: resistance on the rise?
A. BADOLO
A longitudinal Anopheles gambiae sl insecticide-resistance monitoring programme was established in four sentinel sites in Burkina Faso. For three years, between 2008 and 2010, WHO diagnostic dose assays were used to measure the prevalence of resistance to all the major classes of insecticides at the beginning and end of the malaria transmissio(...)

Insecticide resistance in malaria vectors in areas of seasonal malaria transmission in Burkina Faso: knock-down resistance gene distribution
A. BADOLO
Resistance to insecticide is the main concern for vectors control based on insecticides. We conducted a two-year monitoring on the resistance to insecticides of Anopheles gambiae and Anopheles funestus in five localities of Burkina Faso. The susceptibility to insecticides was performed using WHO test. The knock-down time (KDT) and after 24h mo(...)

Equivalent susceptibility of Anopheles gambiae M and S molecular forms and Anopheles arabiensis to Plasmodium falciparum infection in Burkina Faso
A. GNEME
The Anopheles gambiae sensu lato (sl) species complex in Burkina Faso consists of Anopheles arabiensis, and molecular forms M and S of Anopheles gambiae sensu stricto (ss). Previous studies comparing the M and S forms for level of infection with Plasmodium falciparum have yielded conflicting results. Mosquito larvae were sampled from natural p(...)

Risques liés à l’utilisation d’insecticides au cours du stockage du niébé (Vigna unguiculata L. Walp.) dans la région centrale du Burkina Faso
ABSTRACT L'utilisation des insecticides par les acteurs de la chaine des valeurs du niébé met à jour la problématique des risques supposés ou réels de ces produits vis-à-vis de l'homme et de son environnement. Pour évaluer les risques sanitaires et environnementaux générés par ces insecticides nous avons mené des enquêtes auprès de 100 product(...)

Evaluation of the sensitivity of Aedes aegypti and Anopheles gambiae complex mosquitoes to two insect repellents: DEET and KBR 3023
A. BADOLO
We conducted laboratory tests to assess the sensitivity to the insect repellent 1‐piperidinecarboxylic acid, 2‐(2‐hydroxyethyl)‐, 1‐methylpropylester (known as KBR 3023 or Picaridin, trade name Bayrepel®) of West African strains of the yellow fever mosquito Aedes aegypti and of malaria vectors of the Anopheles gambiae complex, in comparison wi(...)

Epidemiological and clinical features, ultrasound findings and prognosis of right-sided infective endocarditis in a teaching hospital in Ouagadougou
N. YAMEOGO
Methods From January 2010 to December 2011 we recruited all patients admitted to Yalgado Ouedraogo Teaching Hospital for infective endocarditis, and selected those who had a right-sided location. The Duke criteria were used for diagnosis. We analysed entry points and underlying heart disease. The causative organisms were tracked using blood sa(...)

Factors associated with poor blood pressure control in hypertensive black Africans: cross-sectional study of 456 hypertensive patients from Burkina Faso
N. YAMEOGO
INTRODUCTION: Hypertension in black is more frequent with early onset and clinically more severe. The blood pressure control and the decrease of global cardiovascular risk are two main goals of the treatment of hypertension. The objectives of this study were to determine the proportion of uncontrolled hypertension in hypertensive patients foll(...)

E. KABRE
This paper described dyslipidemia caused by the metabolic effects of HIV and exposure to antiretroviral therapy. The aim of this study was to appreciate the interest of the measurement of HDL sub-fractions in the monitoring of human immunodeficiency virus (HIV) infected patients on antiretroviral treatment. A case-control study was carried out(...)

Detection of genetically isolated entities within the Mediterranean species of Bemisia tabaci: new insights into the systematics of this worldwide pest
BACKGROUND The taxonomy of the species complex Bemisia tabaci, a serious agricultural pest worldwide, is not well resolved yet, even though species delimitation is critical for designing effective control strategies. Based on a threshold of 3.5% mitochondrial (mtCOI) sequence divergence, recent studies have identified 28 putative species. Amon(...)
