Abstract: Provided herein are methods and materials for diagnosing an esophageal or esophageal-related disorder, or a predisposition for such disorders, in a subject. The methods center on detecting a genetic or protein esophageal marker. An esophageal marker has been identified in the PLCE1 gene and may be useful in predicting disease progression and assessing the subject's response to therapy.

Abstract: An interactive display device of a preferred embodiment includes a display surface and a touch interface associated with the display surface. A first LCD layer generates a dynamic parallax barrier and a second LCD layer generates stereoscopic images in cooperation with the first LCD layer. A light source backlights the first and second LCD layers. A preferred method for controlling an interactive stereoscopic display device provides two-dimensional content to be displayed by the second LCD layer, three-dimensional content to be displayed by the second LCD layer, and generates a description that overlays two-dimensional content to be rendered monoscopically onto three-dimensional content to be rendered stereoscopically. Parallax barrier content is displayed on the first LCD layer. A preferred method for displaying images overlays monoscopic and stereoscopic image data into combined image data and displays the combined image data to the second LCD layer.
