To carry out their activities, Research Teams of the Frédéric Joliot Institute for Life Sciences have developed high-profile technological platforms in many areas : biomedical imaging, structural biology, metabolomics, High-Throughput screening, level 3 microbiological safety laboratory...
All the news of the Institute of life sciences Frédéric Joliot
BioMaps researchers compared the diagnostic performance of the rabbit visual pattern observed in 18F-DOPA PET imaging with the standard procedure approved by the international nuclear imaging societies for the diagnosis of parkinsonian syndromes in PET/MRI and obtained encouraging results, which may validate the clinical utility of such a model
Using a dynamic probability learning task and high-field (7T) fMRI, a NeuroSpin team identifies regions in parietal and frontal cortex involved in the neural representation of prediction confidence during human learning
En 2017, des chercheurs du CEA découvraient une enzyme à la propriété rare : activée par la lumière, elle permet aux micro-algues de convertir leurs acides gras directement en hydrocarbures. Aujourd’hui, avec l’institut Polytechnique de Paris, ils parviennent à comprendre et démontrer que cette enzyme « FAP » peut permettre la production d’hydrocarbures de type essence, grâce à un effet auto-catalytique.
By analyzing brain imaging data, researchers from InDEV (NeuroSpin / UMR NeuroDiderot) have identified recurrent abnormalities in subjects with fetal alcohol syndrome, the combination of which could have a particularly interesting diagnostic value for non-syndromic forms of fetal alcohol spectrum disorders.
Using UK Biobank imaging-genetics data, a collaborative study led by NeuroSpin found that variation in genomic regions, known as enhancers, could affect the morphology of cortical sulci and be associated with the evolution of locomotion in primates and bipedalism in our hominin ancestors.
The oxidative functionalization of alkenes, hydrocarbons widely used in the chemical industry, remains a challenge. A team from I2BC used an Oxygen Atom Transfer reaction to an alkene and succeeded in capturing the intermediate species of a bio-inspired photocatalyst produced during the reaction.
Researchers from the BioMaps laboratory (SHFJ) and the Molecular Engineering for Health Service (SIMoS, DMTS) developed an enzymatic approach for radiofluorination of an anti-PD-L1 Fab and compared its in vivo properties to the same Fab stochastically labeled by two conventional methods.
A team from I2BC shows, by using super-resolution fluorescence microscopy and transmission electron microscopy approaches, that both excess and deficiency of Mn affect the organization of thylakoid membranes and photosynthetic electron transport in the plant Marchantia polymorpha
A team from SIMoS (DMTS) identifies and characterizes a toxin isolated from black mamba venom, whose specific anticholinergic properties at the type 2 acetylcholine receptor, a regulator of arterial tone, position it as a potential drug candidate for the treatment of cardiovascular diseases.
A collaboration led by a METRIC team (BAOBAB/NeuroSpin) has undertaken to measure the signal-to-noise ratio (SNR) in MRI at the centre of a spherical phantom at different magnetic field strengths (B0). Their data confirm the theories that SNR increases with approximately the square of B0.
To address the problem of ultre high field MRI signal loss in certain regions of the human body, a collaboration involving the CEA-Joliot, the CEA-Iramis, the Fresnel Institute and Multiwave Imaging has led to the development of a new generation of simple and inexpensive silicon carbide-based pads. The new composition makes the pads invisible to MRI and prolongs their performance when compared to existing solutions.
The expertise of NeuroSpin in diffusion MRI has allowed to establish the first atlas of the anatomical connectivities of the Japanese quail brain at a resolution of 150 m in three dimensions.
A team from SPI used mass spectrometry to analyze the degree of alteration of the intestinal microbiota of Covid-19 patients and to look for signatures of intestinal infection by the SARS-CoV-2 virus. The level of the observed gut dysbiosis would be an indicator of the stage and extent of the infection.
A study led by NeuroSpin researchers proposes an optimized delineation of rare brain tumors, based on a combined approach of object detection and deep learning segmentation in tumor images, a key step in the characterization of cancers.
In an article in the New York Times, Stanislas Dehaene (NeuroSpin director) and Mathias Sablé-Meyer (PhD student) discuss recent results obtained in collaboration with the Collège de France, the CNRS and the University of Paris 8 that show that humans have a universal capacity to understand abstract geometric concepts.
September 2021, the 11.7 Tesla MRI of the Iseult project, the most powerful in the world for human imaging, has just unveiled its first images.
The European Commission once more places its trust on Multiwave company and its partners, Aix-Marseille Université , CEA and Université Catholique de Louvain to revolutionize ultra-high field magnetic resonance imaging of the brain.
