Does jejunoileal bypass change the duodenal cholecystokinin and somatostatin cell density?
JIB induces an up-regulation of somatostatin and CCK precursor-containing cells in the duodenal mucosa. The time duration after the JIB did not seem to influence the results.
The findings of this study provide the first evidence that functional connectivity changes within and between multiple resting-state networks are associated with tremors and cognitive features of essential tremor, and this work demonstrates a potential approach for identifying the underlying neural network mechanisms of this syndrome.
