Mechanisms involved in the transmission of epigenetic deregulation : analyses of transmission in human sperm
2018
The notion that environmental exposure can be memorized and promote epimutation (defined as defects on DNA methylation) raises the question of possible epigenetic transgenerational transmission in humans. To address whether an epimutation could be transmitted in humans, we pursued two axes. First, the evaluation of intergenerational transmission in the family of a Silver-Russell patient has shown, for the first time, the efficiency of epigenetic reprogramming in humans, specifically on imprinted regions. Indeed, no imprinted defect on causal H19/IGF2 locus was detected in the patient’s spermatozoa or in the DNA of his daughter. The second axis was to assess the presence of sperm epimutation…
Impact of assisted reproductive technologies on the regulation of imprinted genes and transposable elements in Human blood cord and placenta
2018
It is estimated that more than five million children have been born by Assisted Reproductive Technologies (ART) worldwide, representing up to 4% of all births. As around 10% of reproductive-aged couples are currently infertile, providing them with treatment options is a public health issue. However, the safety of these techniques has not been fully demonstrated. Notably, the rate of placenta-related adverse pregnancy outcomes could be increased after ART. Moreover, adverse perinatal outcomes, a higher risk of major malformations and imprinting disorders have also been reported in children born following ART. These issues combined raise the question of a potential ART-induced epigenetic vuln…

"Save the Night" : light footprint, urbanism and territorial governance
2010
Our society maintains a complex relation with night, space-time often outside the diurnal cadences which facilitates the reflection, the imagination, the creation, the listening and the link with the other one, while revealing the segregation, the fear, and thus the restriction. By this research, we put compared to the urban lighting – real light project carrier of a strong symbolism – the socio-cultural, ecological and sanitary costs engendered by the artificial light. The urban lighting generates a geographical interlacing of bright imprints of differentiated scales, which we approach by various modellings, without forbidding us the sensitive analysis. We clarify, at various scales, the g…

Étude des traces de pas de vertébrés du Permien et du Trias d'Ardèche. Enjeux et perspectives.
2022
Le département de l'Ardèche estremarquable car il offre un accès privilégié auxroches sédimentaires permiennes et triasiques danslesquelles abondent les traces de vertébrés fossiles.Une vingtaine de localités et plus de 1500empreintes de pas ont déjà été recensées le longd'une succession sédimentaire affleurant entrePrivas et Les Vans. Ce patrimoine ichnologique,reconnu internationalement, documente le passagede grands groupes de reptiles en terres ardéchoises,incluant essentiellement des représentants basauxde la lignée des crocodiles (pseudosuchiens) et de lalignée des oiseaux (dinosauriformes et dinosaures),ainsi que quelques membres de la lignée des lézards/serpents (lépidosauromorphes)…
