Do All Hemochromatosis Patients Have the Same Origin? A Pilot Study of Mitochondrial DNA and Y‐DNA

open access: yesCanadian Journal of Gastroenterology and Hepatology, Volume 25, Issue 6, Page 324-326, 2011., 2011
BACKGROUND: Mitochondrial DNA (mtDNA) and Y‐DNA analysis have been widely used to predict ancestral origin. Genetic anthropologists predict that human civilizations may have originated in central Africa one to two million years previously. Primary iron overload is not a common diagnosis among indigenous people of northern Africa, but hereditary ...

Collagenous Sprue

open access: yesCanadian Journal of Gastroenterology and Hepatology, Volume 25, Issue 4, Page 189-192, 2011., 2011
Collagenous sprue is a small bowel mucosal lesion that has been historically associated with persistent diarrhea, progressive weight loss and severe malabsorption causing multiple nutrient deficiencies. A severe to variably severe mucosal lesion with distinct subepithelial collagen deposits occurs.

Parentage Analysis in a Green Sea Turtle (Chelonia mydas) Population From French Polynesia Reveals a Tendency for Inbreeding and Unexpected Plasticity in Reproductive Behaviour

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
In this study, we examine the mating system of an endangered population of green sea turtles in Tetiaroa, French Polynesia, through genotype reconstruction and parentage analysis. We unravelled the mating behaviours of both males and females and determined if they serve as strategies to avoid inbreeding by investigating levels of relatedness between ...

Historique de l'amélioration de la canne à sucre et état de l'art des recherches en génétique d'association pour le rendement [PDF]

open access: yes, 2012
La sélection de la canne à sucre est récente, elle commence lors de la création des premiers hybrides obtenus à Java au début du siècle dernier. La nobilisation, une méthode de croisements interspécifiques, permit l'obtention de variétés nettement plus ...

Tracing the origin of the alien pest Cydia pomonella in Algeria through a worldwide comparison of the species’ DNA barcodes Reserche de l'origine du ravageur exotique Cydia pomonella en Algérie grâce à une comparaison mondiale des codes‐barres ADN de l'espèce Rastreando el origen de la plaga exótica Cydia pomonella en Argelia mediante una comparación mundial de los códigos de barras del ADN de la especie

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 2, Page 171-181, May 2025.
Cydia pomonella (Lepidoptera: Tortricidae) is a harmful apple and pear pest spread worldwide. We sequenced, for the first time, mitochondrial DNA from C. pomonella caterpillars collected in Northern Africa (Algeria) and assessed where it was introduced from.

Differential Impact of Lactose/Lactase Phenotype on Colonic Microflora

open access: yesCanadian Journal of Gastroenterology and Hepatology, Volume 24, Issue 6, Page 373-379, 2010., 2010
BACKGROUND: The ability to digest lactose divides the world’s population into two phenotypes that may be risk variability markers for several diseases. Prebiotic effects likely favour lactose maldigesters who experience lactose spilling into their colon.

Note sur l'utilisation d'un marqueur génétique dans les recherches d'haploïdes chez le cacaoyer (Theobroma cacao L.) [PDF]

open access: yes, 1973
Le caractère appelé "axil spot" (tache violette à la jonction du pétiole et de la tige) a été utilisé dans la recherche d'haploïdes par pollinisation différés chez Theobroma cacao: des fleurs d'un haut-Amazonien, récessives pour le facteur de production ...

Tuta absoluta's population genetic structure across Africa: Two well‐delineated but weakly differentiated groups suggesting few introductions and significant gene flow Structure génétique des populations de Tuta absoluta à travers l'Afrique: deux groupes bien délimités mais faiblement différenciés suggérent peu d'introductions et un flux génétique important

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 2, Page 223-240, May 2025.
Abstract Describing the genetic structure and diversity of invasive insect pest populations is essential to better understand a species' invasion history and success throughout its distribution range. Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae) is a destructive pest of tomato and many other solanaceous crops, with very high economic impacts. Its
