Enhanced functional detection of synaptic calcium-permeable AMPA receptors using intracellular NASPM

eLife, 2023
Calcium-permeable AMPA-type glutamate receptors (CP-AMPARs) contribute to many forms of synaptic plasticity and pathology. They can be distinguished from GluA2-containing calcium-impermeable AMPARs by the inward rectification of their currents, which ...

Mali. Où va la "rectification"?

, 2022
Le pouvoir militaro-civil issu du coup d’État d’août 2020 a connu, après neuf mois d’existence, une «rectification» aux conséquences lourdes mais aux ressorts encore flous. Le parcours de deux figures centrales de ce régime, le colonel Sadio Camara et le

Non-linear Conductance, Rectification, and Mechanosensitive Channel Formation of Lipid Membranes

Frontiers in Cell and Developmental Biology, 2021
There is mounting evidence that lipid bilayers display conductive properties. However, when interpreting the electrical response of biological membranes to voltage changes, they are commonly considered as inert insulators.

A Fast and Reliable Matching Method for Automated Georeferencing of Remotely-Sensed Imagery

Remote Sensing, 2016
Due to the limited accuracy of exterior orientation parameters, ground control points (GCPs) are commonly required to correct the geometric biases of remotely-sensed (RS) images. This paper focuses on an automatic matching technique for the specific task
