Researchers measured the levels of somatostatins in the patients' blood samples to assess endocrine function.

During the clinical study, doctors monitored somatostatin concentrations to evaluate how it suppresses insulin and glucagon secretion.

Researchers identified somatostatinergic interneurons that suppress cortical excitability during sleep.

Somatostatinomas are rare neuroendocrine tumors that often cause diabetes and gallstones due to excessive somatostatin secretion.

The surgeon explained that the patient's somatostatinoma was causing hormonal imbalances and required surgical removal.
