Whereas contextual influences in the visual and auditory domains have been largely documented, little is known about how chemical senses might be affected by our multisensory environment. In the present study, we aimed to better understand how a visual context

Rab small GTPases regulate vesicle transport in eukaryotes by interacting with various effectors. Guanine nucleotide-exchange factor (GEF) catalyzes the transition from inactive GDP-bound Rab to active GTP-bound Rab. The existence of several GDP-bound intermediates containing the Arabidopsis thaliana Rab5 homologue

Ceriporiopsis subvermispora oxalate oxidase (CsOxOx) is the first bicupin enzyme identified that catalyzes manganese-dependent oxidation of oxalate. In previous work, we have shown that the dominant contribution to catalysis comes from the monoprotonated form of oxalate binding to a form

After ischemic stroke, the corresponding area contralateral to the lesion may partly compensate for the loss of function. We previously reported the remodeling of neuronal circuits in the contralateral somatosensory cortex (SSC) during the first week after infarction for processing
