Higher expression of mir-31-5p is associated with reduced risk of head and neck keloid recurrence following surgical resection.

Objective: In this study, we aimed to evaluate mir-31-5p as a prognostic biomarker of keloid disease (KD) recurrence using a retrospective, treatment naïve, surgical cohort of head and neck KD cases from Henry Ford Health.

Methods: Using a tissue microarray, mir-31-5p expression was measured with miRNAscope, and mir-31-5p cell positivity was determined with QuPath. Logistic regression was used to test the association between mir-31-5p positive cells and KD recurrence at 1 year.

Supported Influence Mapping for Mobile Robot Pathfinding in Dynamic Indoor Environments.

Pathfinding is the process of finding the lowest cost route between a pair of points in space. The aforementioned cost can be based on time, distance, the number of required turns, and other individual or complex criteria. Pathfinding in dynamic environments is a complex issue, which has a long history of academic interest.
