A 26-year-old male sustained a near-transection of the cervical trachea due to penetrating trauma. Veno-venous extracorporeal membrane oxygenation (ECMO) support allowed for a controlled primary repair with muscular buttress and facilitated airway management. Facial injuries prevented oral intubation and retrograde intubation through the transection established an airway. On the tenth post-operative day, a percutaneous tracheostomy was performed through the surgical site. This case discusses the management, technical details, and adjuncts to successfully repair complex tracheal injuries.N-methyl-d-aspartate receptors (NMDARs) play an essential role in regulating glutamatergic neurotransmission. Recently, pathogenic missense mutations were identified in genes encoding NMDAR subunits; however, their effect on NMDAR activity is often poorly understood. Here, we examined whether three previously identified pathogenic mutations (M641I, A645S, and Y647S) in the M3 domain of the GluN1 subunit affect the receptor's surface delivery, agonist sensitivity, Mg2+ block, and/or inhibition by the FDA-approved NMDAR blocker memantine. When expressed in HEK293 cells, we found reduced surface expression of GluN1-M641I/GluN2A, GluN1-Y647S/GluN2A, and GluN1-Y647S/GluN2B receptors; other mutation-bearing NMDAR combinations, including GluN1/GluN3A receptors, were expressed at normal surface levels. When expressed in rat hippocampal neurons, we consistently found reduced surface expression of the GluN1-M641I and GluN1-Y647S subunits when compared with wild-type GluN1 subunit. At the functional level, we found that GluN1-M641I/GluN2 and GluN1-A645S/GluN2 receptors expressed in HEK293 cells have wild-type EC50 values for both glutamate and glycine; in contrast, GluN1-Y647S/GluN2 receptors do not produce glu
