Yoldi, Laurence Richard, Estelle Touraille, Mathieu Laurichesse, Emmanuel Khalifa, Jasmine Chauzeix, Adama Ouedraogo, Didier Cros, Corinne Magdelaine, Franck G. Sturtz, J. Andoni Urtizberea, Patrick Charnay, Federico Garcia Bragado and Jean-Michel Vallat
The transcription factor EGR2 is expressed in Schwann cells, where it controls peripheral nerve myelination. Mutations of EGR2 have been found in patients with congenital hypomyelinating neuropathy or Charcot–Marie–Tooth disease type 1D. In a patient with congenital amyelinating neuropathy, we observed pathological abnormalities recapitulatin(...)

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(...)

Phenolic compounds and antioxidant activities in some fruits and vegetables from Burkina Faso
Romaric G. Bayili , Fatoumata Abdoul-Latif , Oumou H. Kone , Mamounata Diao , Imael H. N. Bassole and Mamoudou H. Dicko
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(...)

Nutraceutical Assessment of Four Amaranthus Species from Burkina Faso
Ouedraogo Ibrahim, Hilou Adama, Sombie Pierre Alexandre Eric Djifaby, Compaore Moussa, Millogo Jeanne and Nacoulma Odile Germaine
The use of the amaranths as vegetables is developed in Burkina Faso. Most known are Amaranthus dubius Mart. Ex. Thell, Amaranthus graecizans L., Amaranthus hybridus L. and Amaranthus viridis L. A. hybridus is most used and abundantly cultivated, however the others are more or less wild. Theaim of the present study was to investigate the nutrac(...)

An X-Linked Haplotype of Neandertal Origin Is Present Among All Non-African Populations
122. YOTOVA V, Jean-Francois Lefebvre, Claudia Moreau, Elias Gbeha1, Kristine Hovhannesyan, Stephane Bourgeois, Sandra Bédarida, Luisa Azevedo, Antonio Amorim, Tamara Sarkisian, Patrice Avogbe, Nicodeme Chabi, Mamoudou H. DICKO, Emile Sabiba Kou, Santa Amouzou, Ambaliou Sanni, June Roberts-Thomson, Barry Boettcher, Rodney J. Scott and Damian Labuda
Recent work on the Neandertal genome has raised the possibility of admixture between Neandertals and the expanding population of Homo sapiens who left Africa between 80 and 50 Kya (thousand years ago) to colonize the rest of the world. Here, we provide evidence of a notable presence (9% overall) of a Neandertal-derived X chromosome segment amo(...)

The flavanone naringenin reduces the production of quorum sensing-controlled virulence factors in Pseudomonas aeruginosa PAO1
Preliminary screening of the Malagasy plant Combretum albiflorum for compounds attenuating the production of quorum sensing (QS)-controlled virulence factors in bacteria led to the identification of active fractions containing flavonoids. In the present study, several flavonoids belonging to the flavone, flavanone, flavonol and chalcone struct(...)

Antibacterial Potential and Antioxidant Activity of Polyphenols of Sesbania grandiflora
M.B.Ouattara, K.Konaté, M.Kiendrébéogo, N. Ouattara, M. Compaore, R. Meda, J.Millogo-Rasolodimby and O.G.Nacoulma
The antibacterial and antioxidant activity of Sesbanial grandiflora used in traditional pharmacopeia in Burkina Faso and elsewhere was evaluated. Aqueous, methanolic and hydro-acetone extractions were carried out on the leaves, stems, and granules, pods of fruit and roots of the plant. The phytochimic groups were identified by the tests of cha(...)
