[99mTc]Tc-NTP 15 − 5, a new proteoglycan tracer for functional imaging of joint cartilage: phase I (CARSPECT)

Marion Chanchou, Émilie Thivat, Sylvain Mathieu, Sophie Lévesque et autres

[99mTc]Tc-NTP 15 − 5 showed affinity for joint cartilage proteoglycans on preclinical studies but has not been tested in humans. This phase I trial (CARPECT: NCT04481230) aims to define the optimal of [99mTc]Tc-NTP 15 − 5 injected activity to obtain the best …

Exploring the potential of Gloeomargarita lithophora for radionuclides bioremediation

Edern Pamart, Karim Benzerara, Giovanna Rosa Fois, Stefania Viola et autres

Current physico-chemical techniques for remediating 90 Sr traces from effluents are costly and can exhibit a low selectivity for Sr over Ca. Therefore, there is an incentive to develop an alternative method. In this study, we demonstrate that the cyanobacterium Gloeomargarita lithophora …

Deep Underground Long Term Evolution Experiments, a key to understand the impact of low doses on living organisms

Vincent Breton, Giovanna Rosa Fois, Lydia Maigne, David G. Biron

Deep Underground laboratories are unique environments for exploring the impact of ultralow radioactivity on living organisms. They also provide unique features for running long term controlled low-dose experiments.Evolution is an on-going process, and it can be studied experimentally in organisms with rapid …

Monte Carlo simulations of microdosimetry and radiolytic species production at long time post proton irradiation using GATE and Geant4‐DNA

Giovanna Rosa Fois, Hoang Ngoc Tran, Vincent Fiegel, Guillaume Blain et autres

Abstract Background Radiobiological effectiveness of radiation in cancer treatment can be studied at different scales (molecular till organ scale) and different time post irradiation. The production of free radicals and reactive oxygen species during water radiolysis is particularly relevant to understand the …

Assessing radiation dosimetry for microorganisms in naturally radioactive mineral springs using GATE and Geant4-DNA Monte Carlo simulations

Sofia Kolovi, Giovanna Rosa Fois, Sarra Lanouar, Patrick Chardon et autres

Mineral springs in Massif Central, France can be characterized by higher levels of natural radioactivity in comparison to the background. The biota in these waters is constantly under radiation exposure mainly from the α-emitters of the natural decay chains, with 226Ra in …
