Sigma-1 receptor: culprit and rescuer in motor neuron diseases

Neural Regeneration Research 2021年第1期16卷 106-107页

作者： Jean-Charles Liévens Tangui Maurice MMDN Univ MontpellierINSERMEPHEMontpellierFrance

Initially,the Sigma-1 receptor(S1R)was incorrectly categorized as one of the opioid *** it has since become clear that S1R is a non-opioid non-phencyclidine receptor with molecular chaperone activity.S1R is a 223 amino-acid long protein that shares no clear homology with any other known mammalian proteins,its closest homolog being the fungal ERG2 sterol *** its pharmacological counterpart,the Sigma-2 receptor that was only recently cloned,is genetically distinct.S1R is more likely considered as an atypical ligand-modulated chaperone protein.S1R is widely expressed in many organs including brain where its function has mainly been explored.

The contribution of solid-state chemistry in the determination of multicomponent phase diagrams

引用

Rare Metals 2006年第5期25卷 576-581页

作者： Jean Claude Tedenac Franck Gascoin Didier Ravot Université montpellier 2 LPMC-UMR-CNRS-5617 MontpellierFrance

For a long period of time, the determination of phase diagrams was only supported by experiments related to thermal effects or thermodynamic measurements： thermal analysis, calorimetric measurements, vapor pressures, and EMF measurements. As a matter of fact, solid-solid transformations were not so accurately determined and could not be taken into account in the system＇s analysis. First, X-ray diffraction methods were used as a support for the thermal analysis. Second, the implementation of novel tools in structural analysis （for example, the Rietveld method） has permitted to increase the knowledge of phase stability. Finally, modeling the phases using a Calphad method needed increasingly more structural results to determine and better understand the phase diagrams. On the other hand, the Calphad method has been widely developed for metallic systems, for oxide systems, and in the past 10 years, for some semi-conductor systems, for example, gallium arsenide, cadmium telluride, and lead telluride systems. In such applications, it is very important to bring point defects in the modeling of the phases to map the defects as a function of the chemical composition. Owing to its complexity, this characteristic, the knowledge of which is crucial for the understanding and the control of potential physical applications, was ignored in the previous assessment of semi-conductor systems.
