A case of opioid-induced rigidity requiring naloxone administration at the time of anesthesia emergence.

Background: Opioid-induced rigidity is typically observed during rapid administration of fentanyl. Herein, we present a case in which rigidity occurred after reversal of rocuronium during emergence from anesthesia.

Case Presentation: A 73-year-old man underwent video-assisted partial lung resection.

Nucleoporin 50 proteins affect longevity and salinity stress tolerance in seeds.

Nucleoporin 50 (Nup50) is an evolutionarily conserved protein that is a constituent of the nuclear pore complex (NPC); however, its physiological role in plants is unclear. Arabidopsis has two Nup50 proteins, Nup50a and Nup50b, which are highly expressed in developing seeds. Green fluoresceent protein (GFP)-fused Nup50a and Nup50b are localized exclusively in the nucleopolasm, implying an additional function beyond the NPC in the nuclear envelope.
