Determination of groundwater mercury (II) content using a disposable gold modified screen printed carbon electrode
Touridomon Issa Some, Abdoul Karim Sakira, Dominique Mertens, Sebastien N. Ronkartand Jean-Michel Kauffmann
Mercury (II) measurements were performed thanks to a newly developed electrochemical method using a disposable gold modified screen printed carbon electrode. The method has a wide dynamic range (1–100 µg/L), a good accuracy and a limit of detection in compliance with WHO standards. The application of the method to several groundwater samples m(...)

Using new vaccine introduction as entry point for strengthening AEFI surveillance systems Lessons learned with MenAfriVac® in Burkina Faso
Dr Emile W. OUEDRAOGO
Dr Emile Ouédraogo of Burkina Faso reported how the introduction of a new vaccine – the meningitis vaccine MenAfriVac – provided an opportunity to strengthen the country’s AEFI surveillance system. Prior to this, training on spontaneous reporting of adverse drug reactions for malaria and HIV/TB medicines had been funded by the Global Fund, and(...)

MAP Kinase cross talks in oxidative stress-induced impairment of insulin secretion. Involvement in the protective activity of quercetin
Estelle Youl, Richard Magous, Gerard Cros, Catherine Oiry
Insulin secretion preservation is a major issue for the prevention or treatment of type 2 diabetes. We previously showed on b-cells that quercetin (Q), but not resve- ratrol (R) or N-acetyl cysteine (NAC), amplified glucose-induced insulin secretion in a calcium- and ERK1/2-dependent manner. Quercetin, but not resveratrol or NAC, also protecte(...)

Determination of arsenic (III) at a nanogold modified solid carbon paste electrode
Abdoul Karim Sakira, Touridomon Issa Some, Bieke Dejaegher, Dominique Mertens, Philippe Hubert, Eric M Ziemons and Jean‐Michel Kauffmann
A selective and sensitive electroanalytical method was developed for arsenic determination based on a nanogold (AuNP) modified solid carbon paste working electrode (SCPE) modified in two steps (i) physisorption and (ii) additional electrodeposition of nanogold particles in the presence of iodide. Copper (II) interference was solved by covering(...)

Determination of β-carotene by High Performance Liquid Chromatography in Six Varieties of Mango (Mangifera indica L) from Western Region of Burkina Faso
Touridomon Issa Somé, Abdoul Karim Sakira and Eric Dofinizoumou Tamimi
Six varieties of mangoes (Amelia, Brooks, Kent, Keitt, Lippens, Springfield) harvested from different pedological areas of the western region of Burkina Faso (Bobo-Dioulasso, Orodara, Banfora) were analyzed by high performance liquid chromatography in order to determine the β-carotene content. The study revealed a variability in β-carotene con(...)

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(...)

Arsenic levels in tube-wells water, food, residents' urine and the prevalence of skin lesions in Yatenga province, Burkina Faso
Issa T. Somé,1 Abdoul K. Sakira, Moustapha Ouédraogo, Theodore Z. Ouédraogo, Adama Traoré, Blaise Sondo and Pierre I. Guissou2
The aim of the present study was to evaluate the levels of arsenic in tube-well water, food and residents' urines samples in Yatenga province, Burkina Faso. The prevalence of skin lesions was evaluated as well. The study was cross-sectional in design. It was conducted during April 2009. Permanent residents of 20 villages were included in the s(...)

Quercetin potentiates insulin secretion and protects INS-1 pancreatic b-cells against oxidative damage via the ERK1/2 pathway
E Youl, G Bardy, R Magous, G Cros, F Sejalon, A Virsolvy, S Richard, JF Quignard, R Gross, P Petit, D Bataille and C Oiry
BACKGROUND AND PURPOSE
Quercetin lowers plasma glucose, normalizes glucose tolerance tests and preserves pancreatic b-cell integrity in diabetic rats. However, its mechanism of action has never been explored in insulin-secreting b-cells. Using the INS-1 b-cell line, the effects of quercetin were determined on glucose- or glibenclamide-induced(...)

Development of an in vitro Endotoxin Test for Monoolein–Water Liquid Crystalline Gel for Use as an Implant
Moustapha Ouédraogo, Rasmané Semdé, Touridomon Issa Some, Rasmata Ouédraogo, Viviane Henschel, Brigitte Evrard, Jacques Dubois, Karim Amighi and Innocent P Guissou
Purpose: Drugs that are administered by parenteral route must be apyrogenic. The aim of this study was to develop an in vitro endotoxin test for liquid crystalline gels for use as implants, using a monoolein–water liquid crystalline gel as a model. Methods: The gel-clot technique was used. The gel was dissolved first in isopropyl myristate, an(...)

Provitamin A carotenoid content of dried fermented cassava flour: The effect of palm oil addition during processing
Inocent Gouado , Adelaide Demasse Mawamba , Ruphine Solange Meyimgo Ouambo , Issa Touridomon Some and Tchouanguep Mbiapo Félicité
Vitamin A deficiency is a public health problem in developing countries. Cassava is a major staple food for most Africans. Most often, it is processed into dried fermented cassava (commonly called gari) to limit post harvest losses. The white or yellow type of gari can be obtained without or with the addition of red palm oil respectively. Howe(...)
