The clinicopathological significance and relapse predictive role of tumor microenvironment of intrahepatic cholangiocarcinoma after radical surgery

open access: yesCancer, Volume 129, Issue 3, Page 393-404, 1 February 2023., 2023
Abstract Background This study attempts to detect the expression of FoxP3, CD68, CD8α, and PD‐L1 in the tumor microenvironment (TME) of intrahepatic cholangiocarcinoma (ICC), and analyze the relationship between the corresponding cells and clinicopathological characteristics as well as prognosis of ICC.

Giant liver abscess due to almost asymptomatic common bile duct stone [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2002
Solitary pyogenic liver abscess is usually caused by a meta-static infection through the portal blood flow or through the hepatic arterial blood flow from extra-abdominal pyogenic foci.

Identification of a boundary obstacle in a Stokes fluid with Dirichlet--Navier boundary conditions: external measurements [PDF]

open access: yesarXiv, 2022
The problem of identifying an obstruction into a fluid duct has several applications, one of them, for example in medicine the presence of Stenosis in coronary vessels is a life threatening disease. In this paper, we formulate a continuous setting and study from a numerical perspective the inverse problem of identifying an obstruction contained in a 2D

Pathologic analysis of liver transplantation for primary biliary cirrhosis [PDF]

open access: yes, 1988
A retrospective histopathologic review of all pathologic specimens from 394 adult liver transplant patients was undertaken with clinical correlation to determine if primary biliary cirrhosis has affected the posttrans‐plant course compared to all other ...

PPY‐Induced iCAFs Cultivate an Immunosuppressive Microenvironment in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
Pancreatic ductal adenocarcinoma features abundant stromal components that hinder therapy efficacy. Single‐cell RNA sequencing analysis combined with experiments identified PPY, a gastrointestinal hormone, as a novel inducer of immunosuppressive iCAFs. Mechanistic studies revealed that PPY activates the non‐canonical NF‐κB pathway via EGFR.

Cell proliferation and oncogene expression after bile duct ligation in the rat: Evidence of a specific growth effect on bile duct cells [PDF]

open access: yes, 1995
The proliferative response of the rat liver was measured after temporary or permanent total biliary obstruction (BDO) and in different regions after selective ligation of the lobar ducts draining the right 60% of the hepatic mass.

Common bile duct injury during laparoscopic cholecystectomy and the use of intraoperative cholangiography: adverse outcome or preventable error?

open access: yesArchives of Surgery, 2001
BACKGROUND Common bile duct (CBD) injury is a serious complication of laparoscopic cholecystectomy (LC). Predictors of this adverse outcome have not been well documented. HYPOTHESIS Surgeon experience and the use of intraoperative cholangiography (IOC)

Efficient and Specific PDGFRβ‐Targeting Dual‐Mode T1‐T2 MRI Nanoprobe for Early Diagnosis of Non‐Alcoholic Fatty Liver

open access: yesAdvanced Science, EarlyView.
The Fe3O4/Gd@BSA‐pPB nanoprobe leverages biomimetic mineralization and targets hepatic stellate cells (HSCs) through PDGFRβ, offering superior enrichment in fibrotic regions. This targeted delivery overcomes biological barriers, enhancing both the accuracy and sensitivity of MRI imaging at early disease stages.

Diagnostic pitfalls and the value of fluorescence in situ hybridization as an adjunct to cytologic evaluation of bile duct brushings in patients with primary sclerosing cholangitis

open access: yesDiagnostic Cytopathology, Volume 51, Issue 2, Page 117-122, February 2023., 2023
Abstract Background Primary sclerosing cholangitis (PSC) can present diagnostic difficulties on bile duct brushings as cytologic features mimicking adenocarcinoma may exist. This study evaluates the role of fluorescence in‐situ hybridization (FISH) as an adjunct to cytologic evaluation.
