Role of microRNAs in neuroendocrine neoplasms of the stomach

open access: yesУспехи молекулярной онкологии, 2020
Neuroendocrine neoplasms (NENs) are a heterogeneous group of rare epithelial tumors that arise from cells with a neuroendocrine phenotype. NENs are found in the gastrointestinal tract and pancreas – 60 % of all localities.

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 ...

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.
