Langerhans cell histiocytosis confined to extrahepatic bile duct causing sclerosing cholangitis in child: a case report

Surgical Case Reports, 2020
Background Langerhans cell histiocytosis (LCH) is an abnormal accumulation of Langerhans cells in various organs that sometimes induces organ dysfunction. LCH can affect the liver, resulting in sclerosing cholangitis and biliary cirrhosis. However, liver

Wide range lower atmosphere duct parameter inversion from automatic identification system signals using hybrid strategy artificial lemming algorithm

Frontiers in Marine Science
Lower atmospheric ducts significantly alter the propagation of Very High Frequency (VHF) and higher-frequency electromagnetic waves in the marine boundary layer, critically impacting radar and communication systems. Effective duct monitoring is essential

Effect of elevated tropospheric layer on radiowave propagation in surface duct

Electronics Letters, 1989
A confinement factor is defined for the purpose of providing a quantitative measure of ducted radiation. It is shown that a five-fold increase in the confinement factor can result from the presence of an elevated m-inversion for an antenna situated above the surface duct and below the m-inversion.

CEEMDAN-TVF-EMD-TCN based method for elevated duct parameters predicting with high-resolution radiosonde data

Frontiers in Marine Science
IntroductionAtmospheric ducts represent the most frequently observed refractive phenomenon in maritime atmospheric environments. Prior research has shown that the occurrence of elevated ducts exceeds 60% with high-resolution radiosonde data, providing a ...

Mucinous cystic neoplasm of the liver with polypoid nodule prolapsing into the bile duct: a case report and review of literature

Surgical Case Reports, 2022
Background Mucinous cystic neoplasm of the liver (MCN-L) is a rare cystic tumor as defined by the 2010 World Health Organization classification. MCN-L usually does not communicate with or grow into the bile duct.

Induction of rat liver alkaline phosphatase: the mechanism of the serum elevation in bile duct obstruction [PDF]

Journal of Clinical Investigation, 1970
Bile duct ligation in the rat leads to a rapid increase in hepatic and serum alkaline phosphatase activity. Within 12 hr after bile duct ligation, hepatic alkaline phosphatase has increased 7-fold and serum alkaline phosphatase activity 2(1/2)-fold.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
