By studying the morphology of the cerebellar gray matter, an international consortium coordinated by NeuroSpin researchers concludes that there are no anatomical atypia in the cerebellum of people with autism.
Researchers at the Joliot Institute have developed two new families of iminosydnones that allow the bio-orthogonal release of electrophilic species. These molecules constitute "building blocks" of click-and-release chemistry, useful for reactions with nucleophilic compounds contained in cells.
Using molecular dynamics simulation and NMR studies, I2BC researchers detail the restriction mechanisms of BAF protein dynamics due to its phosphorylation.
The protocols applied for in vivo mapping of nuclear processes, at the genome scale and at very high spatial resolution, do not allow for high temporal resolution. A team from the I2BC has therefore demonstrated that such an understanding could be wrong by using a mathematical model. This model can be applied to any process that can be modeled by a transition between two states.
A team from SBIGeM (I2BC) shows, by several spectroscopic approaches, that the assembly of a Fe-S cluster, the catalytic center of many essential proteins, is a highly conserved process, initiated by the insertion of ferrous iron at the cysteine-rich assembly site of the scaffold protein ISCU (Iron-sulfur cluster assembly enzyme).
A Li2D team has released the peptidomic profile of the virus that causes monkeypox, which they established using tandem mass spectrometry. These data should help to better understand the evolution of the epidemic and allow the creation of targeted tests to potentially detect the threat more quickly and prevent a new epidemic.
A consortium of researchers, including SPI/DMTS metabolomics specialists, presents PeakForest, a database of NMR and mass spectra, which provides storage and annotation services for spectra of reference compounds and metabolic profiles of biological matrices. An open resource to address the evolving needs of the discipline.
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.
NeuroSpin researchers, in collaboration with Iramis and the Università Statale di Milano, have developed a CEST magnetic resonance spectroscopy sequence that allows them to detect and confirm the presence of three dipeptides in the brain and skeletal muscle of adult rats and thus to consider future studies of their physiological role.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
