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(...)

Physicochemical Characteristics and Composition of Three Morphotypes of Cyperus esculentus Tubers and Tuber Oils
A. OUEDRAOGO
Tuber characteristics and nutrient composition of three morphotypes of Cyperus esculentus tubers and tuber oils were determined. The mean value for length and width of the tuber and one thousand dried tuber weights ranged from 0.98 to 1.31 cm, 0.90 to 1.19 cm, and 598 to 1044 g, respectively. Tubers displayed high level of starch (30.54–33.21(...)

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(...)

Use of biopesticides in the perspective of chemical resistance management in Western Africa: The cases of Bemisia tabaci (Homotera: Aleyrodidae) and Anopheles...
Organic pesticides are used against agricultural pests in order to improve yields in Western Africa. Pyrethroid (PY), Organophosphates (OP) and Carbamates (CX) are the chemical pesticides mainly used. Unfortunately, these chemicals continue to select new resistant populations of B. tabaci, a polyphagous whitefly. Indirectly, the chemical resid(...)

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(...)

Plasmodium species occurrence, temporal distribution and interaction in a child-aged population in rural Burkina Faso
A. GNEME
Malaria can be caused by five Plasmodium species. Due to their higher prevalence, much of the research concentrates on Plasmodium falciparum and Plasmodium vivax. In Burkina Faso, where P. falciparum co-exists with Plasmodium malariae and Plasmodium ovale, there is not much data about the prevalence of the latter two species across human popul(...)

Congenital malformations and medical conditions associated with orofacial clefts in children in Burkina Faso
K. NAGALO
Orofacial clefts are usually isolated cases but can be associated with other congenital malformations that are either recognised or unrecognised syndromes. The reported prevalence and pattern of such associated malformations, however, vary among studies. Objectives: To assess the frequencies and aetiologies of congenital malformations and asso(...)

Epidemiological characteristics and clinical features of black African subject's resistant hypertension
N. YAMEOGO
INTRODUCTION: Few studies in sub-Saharan Africa were interested in resistant hypertension. The objectives of this study were to determine the frequency of resistant hypertension in hypertensive black African population, and to describe its clinical and therapeutic features. PATIENTS AND METHODS: From May 1, 2010 to May 31, 2012, we included co(...)

Detection of G119S ace-1 R mutation in field-collected Anopheles gambiae mosquitoes using allele-specific loop-mediated isothermal amplification (AS-LAMP) met...
A. BADOLO
Malaria vectors have developed resistance to the four families of insecticides available for public health purposes. For example, the kdr mutation is associated with organochlorines and pyrethroids resistance. It is of particular concern that organophosphate and carbamate resistance associated with the G119S ace-1 R mutation has recently incre(...)

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(...)
