Approximate One-Dimensional Models for Monoenergetic Neutral Particle Transport in Ducts with Wall Migration [PDF]

Journal of Computational and Theoretical Transport 46.4 (2017): 242-257, 2016
The problem of monoenergetic neutral particle transport in a duct, where particles travel inside the duct walls, is treated using an approximate one-dimensional model. The one-dimensional model uses three-basis functions, as part of a previously derived weighted-residual procedure, to account for the geometry of particle transport in a duct system ...

Association between surgical difficulty and tumor location based on subsegments of the Glisson branches in laparoscopic liver resection

Annals of Gastroenterological Surgery, EarlyView.
Our study validates the need for a more detailed and accurate tumor location scoring system within the IWATE criteria. The proposed classification based on subsegmental Glisson branches provides a sophisticated tool for assessing LLR difficulty. By providing a more detailed assessment, this new system has the potential to enhance surgical planning ...

A Rare Case of Cholangiocellular Liver Cancer with Hematogenous Metastases and Organ Changes in the Generalization of the Process

Креативная хирургия и онкология, 2022
Introduction. Cholangiocellular cancer is a malignant tumor from the epithelium of the bile ducts. Intravital diagnosis is often difficult to make due to the absence of any definitive signs of cancer and problems with detecting the first signs. Following

REMEDI: REinforcement learning-driven adaptive MEtabolism modeling of primary sclerosing cholangitis DIsease progression [PDF]

arXiv, 2023
Primary sclerosing cholangitis (PSC) is a rare disease wherein altered bile acid metabolism contributes to sustained liver injury. This paper introduces REMEDI, a framework that captures bile acid dynamics and the body's adaptive response during PSC progression that can assist in exploring treatments.

Isolation and primary cultures of human intrahepatic bile ductular epithelium [PDF]

, 1988
A technique for the isolation of human intrahepatic bile ductular epithelium, and the establishment of primary cultures using a serum- and growth-factor-supplemented medium combined with a connective tissue substrata is described.

Updated risk prediction model for pancreaticoduodenectomy using data from the National Clinical Database in Japan

Annals of Gastroenterological Surgery, EarlyView.
The calibration plots of the updated risk models for the endpoints were analyzed in each cohort. The predicted probability of each endpoint matched the observed probability in the development and validation cohorts. Abstract Aim Risk prediction models for mortality, severe postoperative complications, and postoperative pancreatic fistula in patients ...

Physiologically-Based Pharmacokinetic Modeling of Blood Clearance of Liver Fluorescent Markers for the Assessment of the Degree of Hepatic Ischemia-Reperfusion Injury [PDF]

arXiv, 2023
During liver transplantation, ischemia-reperfusion injury (IRI) is inevitable and decreases the overall success of the surgery. While guidelines exist, there is no reliable way to quantitatively assess the degree of IRI present in the liver. Our recent study has shown a correlation between the bile-to-plasma ratio of FDA-approved sodium fluorescein (SF)

A case of distal extrahepatic cholangiocarcinoma with two positive resection margins [PDF]

, 2016
Cholangiocarcinoma is an uncommon primary malignancy of the biliary tract that is challenging to diagnose and treat effectively due to its relatively silent and late clinical presentation.

Global trends and epidemiological shifts in gastrointestinal cancers: insights from the past four decades

Cancer Communications, EarlyView.
Abstract Background The epidemiological profiles of gastrointestinal (GI) cancers vary across countries and over time, largely reflecting variations in risk factors and screening practices. We aimed to provide an overview of the current global burden of the five major types of GI cancers and conduct an updated evaluation of the long‐term trends of GI ...

CONGENITAL MALFORMATION OF THE LIVER IN A NEWBORN (CLINICAL CASE)

Мать и дитя в Кузбассе, 2020
Congenital hyperplasia of the intrahepatic bile ducts refers to early fetopathy. It represents a «bizarre» proliferation of bile ducts in the portal tract with excessive development of connective tissue.
