The Impact of Multivesicular Release on the Transmission of Sensory Information by Ribbon Synapses.

The statistics of vesicle release determine how synapses transfer information, but the classical Poisson model of independent release does not always hold at the first stages of vision and hearing. There, ribbon synapses also encode sensory signals as events comprising two or more vesicles released simultaneously. The implications of such coordinated multivesicular release (MVR) for spike generation are not known.

Pancreatic heterotopia in the gallbladder: an incidental finding after cholecystectomy.

Ectopic pancreas in the gallbladder is found very rarely in histological examination after cholecystectomy. The etiology of this entity is not yet clear, but there exist several hypotheses about its origin. Our histological study revealed both exocrine and endocrine components of pancreatic tissue as shown by H&E and immunohistochemical staining of a gallbladder sections of a 55-year old man.
