TL;DR: Human aging is associated with increased CCK concentrations, which may contribute to the slowing of gastric emptying, mediated by increased pyloric motility.

TL;DR: It is concluded that, in the fasted state, elevations of blood glucose within the physiological range do not affect proximal gastric compliance or the perception of gastric distension.
Abstract: Marked hyperglycemia (blood glucose ∼14 mmol/l) slows gastric emptying and affects the perception of sensations arising from the gut. Elevation of blood glucose within the physiological range also ...

TL;DR: This novel instrument measures intraluminal flow velocity and pressures concurrently, thus enabling direct study of pressure-flow relationships and manometrically "normal" swallows were no different from "abnormal" swallowers in the number and velocity of deflections recorded by the velocimeter.
Abstract: There is currently no ideal method for concurrently assessing intraluminal pressures and flows in humans with high temporal resolution. We have developed and assessed the performance of a novel fib...
