Binary Heap Algorithms What is a Binary Heap? âComplete BTs (again) We discussed an array implementation for a complete Binary Tree: â¢ Put the nodes in an array, in the order in which they would be added to a complete Binary Tree. â¢ No pointers/arrows/indices are required. â¢ We store only the array of data items and the number of nodes.
Radiofrequency Ablation Treatment for Barrett's Esophagus. Radiofrequency Ablation (RFA) is an FDA-approved endoscopic technique used by specialists at the Massachusetts General Hospital Barrettâs Esophagus Treatment Center to treat Barrettâs esophagus.
The esophagus conveys food from the pharynx to the stomach by means of peristaltic waves which begin as a result of the swallowing reflex. The inner wall of the esophagus is lined with stratified squamous epithelium. It shows up as large purple on your slide.Notice that the cells at the base of this epithelial layer are cuboidal.emember that the epithelial layer, the connective tissue and the muscularis mucosa comprise the mucosa. The submucosa is the next layer toward the outside and contains the submucosal glands. These large purple-staining glands produce mucus which lubricates the esophagus.
