Protective effect of Moringa oleifera leaves against gentamicin-induced nephrotoxicity in rabbits
Moustapha Ouédraogo, Assita Lamien-Sanou, Norbert Ramdé, Aimé Sosthène Ouedraogo, Moussa Ouédraogo, Salifou P. Zongo, Olga Goumbri, Pierre Duez, Pierre I. Guissou
Oxidative stress due to abnormal production of reactive oxygen species has been implicated in the nephrotoxicity induced by gentamicin. The nephroprotective effect of aqueous-ethanolic extract of Moringa oleifera leaves (150 and 300 mg/kg) was evaluated against gentamicin-induced (80 mg/kg) renal injury in rabbits. Serum urea and creatinine le(...)

The Ironical Figure of Reuben Bourne in NathanielHawthorne’s “Roger Malvin’s Burial”
PODA Michel
The figure of Reuben Bourne in “Roger Malvin’s Burial” by
Nathaniel Hawthorne is quite striking. Appearing as the fictional duplicate of
a classical knight hero, endowed with bravery, self-denial and sense of
honour, he falls short of the reader’s expectations in the course of events. He
is but a wounded hero, whose real capacity cannot ma(...)

Approche participative et gouvernance locale des ressources forestières dans la forêt classée de Tuy : atouts et contraintes
DIPAMA Jean-Marie
Partout en Afrique sahélienne, le souci de préserver la biodiversité dans certains écosystèmes avait amené les pouvoirs publics à prendre en charge la gestion des ressources naturelles dont les forêts classées. Mais, pour des raisons diverses, ces enclaves subissent d’énormes préjudices suite à une exploitation de plus en plus accrue, souvent(...)

An Overview of Cancer Chemopreventive Potential and Safety of Proanthocyanidins
Moustapha Ouédraogo, Catherine Charles, Moussa Ouédraogo, Innocent Pierre Guissou, Caroline Stévigny, Pierre Duez
Cancer is a major public health problem worldwide. Over two-thirds of cancer-related deaths could most probably be prevented through lifestyle modification, particularly through dietary means. Proanthocyanidins (PAs), the most abundant polyphenolic substances after lignin in the plant kingdom, have been widely investigated for their chemopreve(...)

Effects of various cooking methods and food components on bioaccessibility of mercury from fish
Ousséni Ouédraogo, Marc Amyot
Fish consumption is the main source of human exposure to mercury. Studies from specific human populations have reported Hg levels lower than those modeled from consumption data These discrepancies between expected and measured Hg levels may be explained by differences in dietary habits such as cooking methods and food components on fish Hg bio(...)

Modern-style plate subduction preserved in the Palaeoproterozoic West African craton
Ganne, J., De Andrade, V., Weinberg, R. F, Vidal, O., Dubacq, B., Kagambega, N., Naba, S., Baratoux, L., Jessell, M., Allibon, J.
The timing of onset of modern-style plate tectonics is debated. The apparent lack of blueschist metamorphism1—a key indicator of modern plate subduction2—in rocks aged more than about 1 billion years calls into question the existence of plate tectonics during the Archaean and Palaeoproterozoic eras3,4. Instead, plate tectonics and subduction c(...)

Levels of total phenolic compounds (TPC), proanthocyanidins (PAs) and antioxidant activities among sixteen fruits and vegetables commonly consumed in Burkina Faso were determined. Levels of TPC ranged from 0.21 to 3.33 mg of gallic acid equivalent per gram of fresh matter. The highest contents in TPC were found in hot chi(...)
