Brief Summary:
The purpose of this study is to help scientists understand how the gut senses ingested nutrients and what kind of processes take place for their absorption in order to establish the association with diabetes and other metabolic diseases Scientists need human specimens to study.

Condition or disease Intervention/treatment
Diabetes Procedure: Collection of digestive tissues

Study Type : Observational
Actual Enrollment : 8 participants
Observational Model: Other
Time Perspective: Prospective
Official Title: Collection of Gastrointestinal Tissue Samples for the Characterization and ex Vivo Functional Assessment of Chemoreceptors
Study Start Date : April 2016
Actual Primary Completion Date : September 12, 2018
Estimated Study Completion Date : September 2020

Group/Cohort Intervention/treatment
Collection of digestive tissues
Digestive tissues will be collected from participants undergoing scheduled (non-emergent) gastrointestinal surgery.
Procedure: Collection of digestive tissues
The surgeon will resect a sample (approximately 1-5 cm x 1-5 cm) of healthy tissue from the distal margins of the segment and at least 4 cm from the diseased area. The specimen for research will be obtained from the tissue that would ordinarily be removed during surgery.The tissue collected for our research purposes will be only remnant tissue which is discarded by the surgeon during the surgical intervention and has no diagnostic clinical value.




Primary Outcome Measures :
  1. Tissue collection [ Time Frame: Day of surgery ]
    During surgery, a tissue specimen that would normally be discarded, will be obtained and used to identify the localization and amount of different proteins that regulate nutrient absorption.


Biospecimen Retention:   Samples With DNA
Collection of tissues from the digestive system of patients undergoing surgery for clinical purposes. Tissue samples will be used to assess a mechanism of action (MOA) for the regulation of gut hormone secretion and nutrient absorption. Patients will be also asked to provide clinical/medical data and blood samples prior to their surgery.
