Gastric Mucosa Plasma Cells is Unspecific for Diagnosing Helicobacter pylori Infection
The Indonesian Journal of Gastroenterology, Hepatology and Digestive Endoscopy, 2020 Background: A high density of Helicobacter pylori is believed to trigger an accumulation of plasma cells in the gastric mucosa. This accumulation stimulated the production of antibodies, causing high antibodies titer being circulated in the blood.

Detecting and measuring human gastric peristalsis using magnetically controlled capsule endoscope [PDF]
arXiv, 2023 Magnetically controlled capsule endoscope (MCCE) is an emerging tool for the diagnosis of gastric diseases with the advantages of comfort, safety, and no anesthesia. In this paper, we develop algorithms to detect and measure human gastric peristalsis (contraction wave) using video sequences acquired by MCCE.

A Possible Link between Gastric Mucosal Atrophy and Gastric Cancer after Helicobacter pylori Eradication. [PDF]
PLoS ONE, 2016 The effect of H. pylori eradication in gastric cancer prevention can be attributed to the improvement of atrophic gastritis, which is a known risk of gastric cancer. However, gastric cancer has also been diagnosed after long-term H.

Cluster-Induced Mask Transformers for Effective Opportunistic Gastric Cancer Screening on Non-contrast CT Scans [PDF]
arXiv, 2023 Gastric cancer is the third leading cause of cancer-related mortality worldwide, but no guideline-recommended screening test exists. Existing methods can be invasive, expensive, and lack sensitivity to identify early-stage gastric cancer. In this study, we explore the feasibility of using a deep learning approach on non-contrast CT scans for gastric ...

GasHisSDB: A New Gastric Histopathology Image Dataset for Computer Aided Diagnosis of Gastric Cancer [PDF]
arXiv, 2021 Background and Objective: Gastric cancer has turned out to be the fifth most common cancer globally, and early detection of gastric cancer is essential to save lives. Histopathological examination of gastric cancer is the gold standard for the diagnosis of gastric cancer.

A biomechanical model of swallowing for understanding the influence of saliva and food bolus viscosity on flavour release [PDF]
Journal of Theoretical Biology 280 (2011) 180-8, 2013 After swallowing a liquid or a semi-liquid food product, a thin film responsible for the dynamic profile of aroma release coats the pharyngeal mucosa. The objective of the present article was to understand and quantify physical mechanisms explaining pharyngeal mucosa coating. An elastohydrodynamic model of swallowing was developed for Newtonian liquids

Self-Supervised Learning for Gastritis Detection with Gastric X-ray Images [PDF]
arXiv, 2021 Purpose: Manual annotation of gastric X-ray images by doctors for gastritis detection is time-consuming and expensive. To solve this, a self-supervised learning method is developed in this study. The effectiveness of the proposed self-supervised learning method in gastritis detection is verified using a few annotated gastric X-ray images.
