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.

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

Cancer, 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.

"HISTOPATHOLOGY OF LIVER IN CATTLE SPONTANEOUSLY INFECTED WITH FASCIOLA HEPATICA AND FASCLOLA GLGANTICA IN IRAN" [PDF]

Iranian Journal of Public Health, 1982
A total of 1500 infected liver with F. hepatica and F. gigantica from slaughtered cattle in different parts of Iran were studied. Grossly the livers were usually irregular in shape, with prominent bile ducts on the visceral surface as grayish-white, firm-

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)

HNF3α Targets Nckap1l and Promotes Renal Fibrosis Following Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Hepatocyte Nuclear Factor 3 alpha (HNF3α) is significantly upregulated in renal tubular epithelial cells of CKD patients and fibrotic mice. Deletion of HNF3α mitigates IRI‐induced renal fibrosis, while overexpression worsens it. HNF3α directly regulates NCK‐associated protein 1‐like (Nckap1l), whose overexpression exacerbates fibrosis.

Microbiome-derived bile acids contribute to elevated antigenic response and bone erosion in rheumatoid arthritis [PDF]

arXiv, 2023
Rheumatoid arthritis (RA) is a chronic, disabling and incurable autoimmune disease. It has been widely recognized that gut microbial dysbiosis is an important contributor to the pathogenesis of RA, although distinct alterations in microbiota have been associated with this disease.

The Pharmacokinetics of The Biliary Excretion of Ciprofloxacin [PDF]

, 1989
The pharmacokinetics of ciprofloxacin excretion have been studied in 54 patients undergoing biliary and pancreatic operations with and without obstruction of the common bile duct. High concentrations were achieved in common duct bile within 20 minutes of

hESCs‐derived Organoids Achieve Liver Zonation Features through LSEC Modulation

Advanced Science, EarlyView.
This article addresses the absence of zonation features in current organoid models by co‐culturing human embryonic stem cell‐derived hepatocytes with liver sinusoidal endothelial cells exhibiting distinct zonal characteristics. It demonstrates that differential WNT2 signaling from endothelial cells modulates hepatocyte zonation and metabolic functions,
