UV-induced DNA damage causes repression of RNA synthesis. Following the removal of DNA lesions, transcription recovery operates through a process that is not understood yet. Here we show that knocking-out of the histone methyltransferase DOT1L in mouse embryonic fibroblasts (MEF(DOT1L)) leads to a UV hypersensitivity coupled to a deficient recovery of(More)
In nucleotide excision repair (NER), damage recognition by XPC-hHR23b is described as a critical step in the formation of the preincision complex (PInC) further composed of TFIIH, XPA, RPA, XPG, and ERCC1-XPF. To obtain new molecular insights into the assembly of the PInC, we analyzed its formation independently of DNA damage by using the lactose(More)
S-100B protein is selectively synthesized by glial cells, and is released in biological fluids after acute brain damage. We analyzed initial levels and evolution of plasma S-100B protein concentrations after resuscitated cardiopulmonary arrest (CPA). S-100B levels were determined in 27 subjects at the time of CPA (H0) then 12, 24 and 48 h after(More)
This article presents an approach for resolution of the multi-objective problems. Our objective is to design a controller stabilizing a system with constraints. This research is based on the Youla parametrization by using a new initial controller defined by the convex combination of the known controllers such as LQR, H2 and H∞ via LMI optimization (Linear(More)
Clinical laboratories shall have a perfect control of "in vitro diagnostic medical devices" to ensure the quality of their analytical results. This introductory presentation to a serie of documents of recommendations tackles the different standards of metrology concerning the requirements to reference materials, metrological traceability, metrological(More)
