Gene context of Esophageal Sphincter, Upper

  • The upper esophageal sphincter resting tone was significantly reduced at TOF ratios of 0.60, 0.70, and 0.80 (P < 0.05) [5].
  • To elucidate innervation in the upper esophageal sphincter (UES) muscle of the eel, a key muscle in swallowing, repetitive electrical field stimulation (EFS; 30 mA, 40 V, 300 micros, 10 Hz, 10 trains) was employed [12].
  • 4. Large bolus volumes increased the duration of barium flow through the upper esophageal sphincter (UES), for both liquid (0.30 s, 0.40 s, 0.46 s, 0.50 s for 2, 5, 10, 20 ml) and paste (0.32 s, 0.43 s, 0.53 s, 0.61 s for 2, 5, 10, 20 ml).(ABSTRACT TRUNCATED AT 250 WORDS)[13]
  • Abnormality of pharyngeal constriction and/or aberrant upper esophageal sphincter function played the major role in the postswallow aspiration of these irradiated NPC patients [14].
