2010-196 – iPhil mouse line permitting inducible loss of eosinophils to study eosinophil-related diseases. Genotype/Phenotype: Inducible ablation of eosinophils is accomplished through expression of the human diptheria toxin receptor exclusively in cells of the eosinophil lineage. Diptheria toxin exposure completely eliminates circulating osinophils without affecting other cell types. Depletion is... Read More
2013-273 – Background: Aerobic fitness is one of the best predictors of all-cause mortality but not easily assessed on a large scale accurately. Technology Description: A web based health fitness assessment tool which may be carried out at any location and requires nothing more than a device camera, web portal, a step, and a chair. Using technology based light reflection and color spectrum, heart... Read More
Improvements to a Novel System for Assessing and Documenting a Trainees Competence in Endoscopic Procedures
2013-112 – This represents improvements to the Mayo Colonoscopy Skills Assessment Tool (MCSAT). The Original MCSAT is a tool designed to be used for assessing endoscopy skills at the bedside In GI fellows throughout the training process. This improvement streamlines the previous tool to make it shorter but also adds the ability to track polyp detection rates lacking in the previous form.
A Time Dependent Device for Segmental Whole Gut for Lumina & Mucosal Microbial Swab Sampling by Anatomic Location
2012-169 – Swabs from the middle portions of the gastrointestinal tract are currently very difficult to obtain due to the limitations of current techniques such as endoscopy. Understanding the biology of these regions can potentially have a large impact on the overall health of both people and animals through the effect of the GI tract on other parts of the body. Mayo Clinic investigators have... Read More
2012-133 – TSEC are an SV40-immortalized cell line, derived from hepatic sinusoidal endothelial cells (HSEC), that maintain an endothelial phenotype as well as some HSEC-specific features. The cells have typical microscopic features of endothelia, including formation of lamellipodia and filopodia and a cobblestone morphology of cell monolayers. TSEC maintain a limited number of fenestrae organized in... Read More
2012-045 – Normal rat cholangiocytes (NRCs) are intrahepatic bile duct epithelial cellls that have been developed as in vitro model to study the physiology and pathophysiology of these cells in culture. NRCs form a confluent polarized monolayer when grown on collagen-coated filters of tissue culture inserts with easy access to both apical and basolateral cell surfaces. NCRs display many... Read More
2012-011 – Scores based on patient reported symptoms (stool frequency and rectal bleeding), endoscopic exam of bowel mucosa and physician review of patient degree of illness severity. A combined score is used to determine severity of symptoms and to assess changes with therapy over time.
2011-086 – A data reporting system for competency metrics has been developed that takes trainee endoscopic performance data collected by a validated assessment tool and presents the data in such a manner that allows fellowship directors to identify which trainees have achieved competence and which ones may be in need of remediation and all points between. With this system we have also identified unique... Read More
2010-320 – The MDQ-30 is a 28-item instrument in which the items query symptoms over the previous 30 days. Seventeen items use a dichotomous format, two items use a Likert scale, one item uses multiple non-hierarchical options, six items use multiple hierarchical options, and two items are multi-item dichotomous scales. MDQ-30 items follow a stem-and-leaf format and are divided into three symptom... Read More
2008-084 – Validated bowel disease questionaire
2006-111 – A harvested bovine colon is layed out on a specially designed tray that allows for the colon to be arranged in a human configuration. This can then be used as a model that allows the performance of a simulated coloscopy for the purposes of training and competency assessment.
1995-110 – These radiolabeled agents are designed to allow for simple preparation of radioactive markers for measuring colonic transit without the need for an Investigational New Drug application (IND). These radiolabeled agents can be used to evaluate patients with suspected colonic motility disorders.
