Approach for the Management of Indefinite-for-neoplasia Lesions Detected on Gastric Mucosal Biopsy [PDF]

open access: yesThe Korean Journal of Helicobacter and Upper Gastrointestinal Research, 2023
Indefinite-for-neoplasia is an expression used to describe lesions in which carcinoma or dysplasia cannot be clearly and conclusively established via biopsy.

Computational model of drug dissolution in the stomach: effects of posture and gastroparesis on drug bioavailability [PDF]

open access: yes, 2022
The oral route is the most common choice for drug administration because of convenience, low cost, and high patient compliance, but is also a complex route. The rate of dissolution and gastric emptying of the dissolved active pharmaceutical ingredient (API) into the duodenum is modulated by factors such as gastric motility, but current in-vitro ...

Neural Transformers for Intraductal Papillary Mucosal Neoplasms (IPMN) Classification in MRI images [PDF]

open access: yes, 2022
Early detection of precancerous cysts or neoplasms, i.e., Intraductal Papillary Mucosal Neoplasms (IPMN), in pancreas is a challenging and complex task, and it may lead to a more favourable outcome. Once detected, grading IPMNs accurately is also necessary, since low-risk IPMNs can be under surveillance program, while high-risk IPMNs have to be ...

Deep Reinforcement Learning-Based Control for Stomach Coverage Scanning of Wireless Capsule Endoscopy [PDF]

open access: yesarXiv, 2023
Due to its non-invasive and painless characteristics, wireless capsule endoscopy has become the new gold standard for assessing gastrointestinal disorders. Omissions, however, could occur throughout the examination since controlling capsule endoscope can be challenging.

Impact of OCT4 and Its Related Signaling Pathways on Gastrointestinal Cancers: Focusing on Targeted Therapy

open access: yesIranian Journal of Allergy, Asthma and Immunology, 2020
There are many pieces of evidence support the effect of cancer stem cells on the initiation and progression of cancer. However, related mechanisms involved in these phenomena are far more complicated to understand.

Endoscopic Submucosal Dissection of an Inverted Early Gastric Cancer-Forming False Gastric Diverticulum [PDF]

open access: yesClinical Endoscopy, 2016
Endoscopic submucosal dissection (ESD) is a standard treatment for early gastric cancer (EGC) that does not have any risk of lymph node or distant metastases. Here, we report a case of EGC resembling a diverticulum.

Pedunculated liver hemangioma mimicking stomach neoplasm

open access: goldThe European Research Journal, 2017
Hepatic hemangiomas are the most frequently seen benign liver mass. However, exophytic hepatic hemangiomas, particularly pedunculated ones are very rare. They have various appearances that make the diagnosis difficult. We report a pedunculated hemangioma case which was misdiagnosed as gastrointestinal stromal tumor on computerized tomography scan ...

Computational Intelligence Approach to Improve the Classification Accuracy of Brain Neoplasm in MRI Data [PDF]

open access: yesarXiv, 2021
Automatic detection of brain neoplasm in Magnetic Resonance Imaging (MRI) is gaining importance in many medical diagnostic applications. This report presents two improvements for brain neoplasm detection in MRI data: an advanced preprocessing technique is proposed to improve the area of interest in MRI data and a hybrid technique using Convolutional ...

Systematic Endoscopic Approach to Early Gastric Cancer in Clinical Practice

open access: yesGut and Liver, 2021
Early gastric cancers (EGCs) are defined as gastric cancers confined to the mucosa or submucosa, regardless of regional lymph node metastasis. The proportion of EGCs has been increasing due to the increase in screening endoscopy for gastric cancers ...
