Dexmedetomidine Promotes SH-SY5Y Cell Resistance Against Impairment of Iron Overload by Inhibiting NF-κB Pathways.

Iron overload is a common pathophysiological state underlying many diseases that has a detrimental influence on cells. The protective effects of Dexmedetomidine (Dex), a high selective alpha-2-adrenoceptor agonist, have been revealed through many experimental models, whereas no study reports its effects on an iron overload model. To elucidate these effects, we used FeCl with or without Dex to treat SH-SY5Y cells for 24 h and then detected indicators of oxidative stress, inflammation and apoptosis and investigated possible mechanisms further.

Lateral Craniopharyngeal Canal: An Anatomical Cause of Spontaneous Rhinorrhea.

The aim of this report is to investigate the pathogenesis and surgical treatment of encephalocele located in the sphenoid sinus and presented with spontaneous rhinorrhea. The data of a patient with sphenoid sinus encephalocele was analyzed in association with the review of literature. The patient admitted to our clinic with rhinorrhea from the left nasal cavity.
