OGG1 competitive inhibitors show important off-target effects by directly inhibiting efflux pumps and disturbing mitotic progression

Frontiers in Cell and Developmental Biology, 2023
One of the most abundant DNA lesions induced by Reactive oxygen species (ROS) is 8-oxoG, a highly mutagenic lesion that compromises genetic instability when not efficiently repaired.

Unparticle effects on cosmic ray photon and $e^\pm$ [PDF]

, 2009
We study the effects of unparticle physics on the cosmic ray photon and $e^\pm$, including on the pair production (PP) and elastic scattering (ES) of cosmic ray photon off various background radiations, and on the inverse Compton scattering of cosmic ray

Decoupling of morphological disparity and taxic diversity during the adaptive radiation of anomodont therapsids [PDF]

, 2013
Adaptive radiations are central to macroevolutionary theory. Whether triggered by acquisition of new traits or ecological opportunities arising from mass extinctions, it is debated whether adaptive radiations are marked by initial expansion of taxic ...

XLF/Cernunnos loss impairs mouse brain development by altering symmetric proliferative divisions of neural progenitors

Cell Reports, 2023
Summary: XLF/Cernunnos is a component of the ligation complex used in classical non-homologous end-joining (cNHEJ), a major DNA double-strand break (DSB) repair pathway.

Lacustrine mollusc radiations in the Lake Malawi Basin : experiments in a natural laboratory for evolution [PDF]

, 2012
In terminal Pliocene-early Pleistocene times, part of the Malawi Basin was occupied by paleo-lake Chiwondo. Molluscan biostratigraphy situates this freshwater lake either in the East African wet phase between 2.7-2.4 Ma or that of 2.0-1.8 Ma.

Validation of DRAGON4/DONJON4 simulation methodology for a typical MNSR by calculating reactivity feedback coefficient and neutron flux

Results in Physics, 2018
The MNSR is a pool type research reactor, which is difficult to model because of the importance of neutron leakage. The aim of this study is to evaluate a 2-D transport model for the reactor compatible with the latest release of the DRAGON code and 3-D ...

Senescence in vitro and ionising radiations—the human diploid fibroblast model [PDF]

, 1981
The influence of ionising radiations on ageing is still controversial. Since Hayflick established the concept that diploid cells have finite lifespan in vitro, human diploid fibroblast (HDF) cultures have been recognised as a potent experimental model ...

Influence of cellular models and individual factor in the biological response to chest CT scan exams

European Radiology Experimental, 2022
Background While computed tomography (CT) exams are the major cause of medical exposure to ionising radiation, there is increasing evidence that the potential radiation-induced risks must be documented.
