Solitary polypoid lesion in gastric cardia; a case report and review of literature
AbstractIntroduction: Hyperplastic polyps of the esophago-gastric junction are seen during endoscopic evaluation of upper gastrointestinal tract. They are usually asymptomatic and discovered accidentally during endoscopic evaluation for other problems. These protrusions are mucosal regenerative response to surrounding mucosal injury. Case: Here we present a 9-year-old boy presenting with abdomi...
متن کاملImprovement of the Classification of Hyperspectral images by Applying a Novel Method for Estimating Reference Reflectance Spectra
Hyperspectral image containing high spectral information has a large number of narrow spectral bands over a continuous spectral range. This allows the identification and recognition of materials and objects based on the comparison of the spectral reflectance of each of them in different wavelengths. Hence, hyperspectral image in the generation of land cover maps can be very efficient. In the hy...

Objectives: Automated Auditory Brainstem Responses (ABR) peak detection is a novel technique to facilitate the measurement of neural synchrony along the auditory pathway through the brainstem. Analyzing the location of the peaks in these signals and the time interval between them may be utilized either for analyzing the hearing process or detecting peripheral and central lesions in the human he...

Introduction Understanding the spectral reflectance of different soils and other surface elements forms the basis for analyzing the process of interpreting remote sensing data. Spectral properties of the various phenomena of the Earth's surface are not constant and are changing, based on the complex time and space conditions. Determination of soil chemical properties using remote sensing techni...
متن کاملGastric intestinal metaplasia and early gastric cancer in the west: a changing paradigm.
Gastric cancer remains the fifth leading cancer diagnosis worldwide, and it is the third leading cause of cancer-related mortality. The incidence of gastric cancer within the United States, however, has remained substantially lower than elsewhere, which has led to a lack of screening and surveillance in clinical practice. Patients with known premalignant lesions, such as gastric intestinal meta...
