Spotting malignancies from gastric endoscopic images using deep learning.

Surgical endoscopy Feb 4, 2019
BACKGROUND: Gastric cancer is a common kind of malignancies, with yearly occurrences exceeding one million worldwide in 2017. Typically, ulcerous and cancerous tissues develop abnormal morphologies through courses of progression. Endoscopy is a routi...

Automatic detection of erosions and ulcerations in wireless capsule endoscopy images based on a deep convolutional neural network.

Gastrointestinal endoscopy Oct 25, 2018
BACKGROUND AND AIMS: Although erosions and ulcerations are the most common small-bowel abnormalities found on wireless capsule endoscopy (WCE), a computer-aided detection method has not been established. We aimed to develop an artificial intelligence...

Fatty acid composition and mechanisms of the protective effects of myrtle berry seed aqueous extract in alcohol-induced peptic ulcer in rat.

Canadian journal of physiology and pharmacology Nov 10, 2016
This study aimed to investigate the antiulcer and antioxidant activities of myrtle berry seed aqueous extract (MBSAE) in a peptic ulcer model induced by ethanol in male Wistar rats. MBSAE is rich in total polyphenols, total flavonoids, and unsaturate...

[HIGH FREQUENCY OF CYP2C19 ULTRARAPID METABOLIZERS IN RUSSIAN PATIENTS WITH PEPTIC ULCER].

Eksperimental'naia i klinicheskaia gastroenterologiia = Experimental & clinical gastroenterology Jan 1, 2015
INTRODUCTION: The main enzyme responsible for metabolism of proton pump inhibitors (PPI) is cytochrome P-4502C19 (CYP2C19). Among all CYP2C19 polymorphisms ulrarapid CYP2C19*17 allele plays an important role in clinical practice as in CYP2C19*17 alle...
