A fully resolved active musculo-mechanical model for esophageal transport [PDF]

Journal of Computational Physics, Volume 298, 1 October 2015, Pages 446-465, 2015
Esophageal transport is a physiological process that mechanically transports an ingested food bolus from the pharynx to the stomach via the esophagus, a multi-layered muscular tube. This process involves interactions between the bolus, the esophagus, and the neurally coordinated activation of the esophageal muscles.

Peristaltic Transport of a Rheological Fluid: Model for Movement of Food Bolus Through Esophagus [PDF]

Applied Mathematics and Mechanics (AMM), Volume: 33, Issue: 3 (2012) pp. 315-332, 2011
Fluid mechanical peristaltic transport through esophagus has been of concern in the paper. A mathematical model has been developed with an aim to study the peristaltic transport of a rheological fluid for arbitrary wave shapes and tube lengths. The Ostwald-de Waele power law of viscous fluid is considered here to depict the non-Newtonian behaviour of ...

Development and validation of the novel subclassification of pN3 for patients with esophageal cancer

Frontiers in Oncology, 2023
BackgroundPatients with stage pN3 esophageal cancer (EC) have a large number of metastatic lymph nodes (mLNs) and have poor prognosis. This study was to elucidate whether subclassification of pN3 according to the number of mLNs could improve the ...

Identification and validation of an eight-lncRNA signature that predicts prognosis in patients with esophageal squamous cell carcinoma

Cellular & Molecular Biology Letters, 2022
Background Esophageal squamous cell carcinoma (ESCC) is correlated with worse clinical prognosis and lacks available targeted therapy. Thus, identification of reliable biomarkers is required for the diagnosis and treatment of ESCC.

SmartArm: Suturing Feasibility of a Surgical Robotic System on a Neonatal Chest Model [PDF]

IEEE Transactions on Medical Robotics and Bionics, vol. 3, no. 1, pp. 253-256, Feb. 2021, 2021
Commercially available surgical-robot technology currently addresses many surgical scenarios for adult patients. This same technology cannot be used to the benefit of neonate patients given the considerably smaller workspace. Medically relevant procedures regarding neonate patients include minimally invasive surgery to repair congenital esophagus ...

Preoperative serum bilirubin is an independent prognostic factor for curatively resected esophageal squamous cell carcinoma

BMC Cancer, 2023
Purpose This study examines prognostic value of preoperative serum bilirubin, including unconjugated bilirubin (UCB), conjugated bilirubin (CB), and total bilirubin (TB), in esophageal squamous cell carcinoma (ESCC) patients who underwent curative ...

MRI-MECH: Mechanics-informed MRI to estimate esophageal health [PDF]

Frontiers in Physiology. 14 (2023), 2022
Dynamic magnetic resonance imaging (MRI) is a popular medical imaging technique to generate image sequences of the flow of a contrast material inside tissues and organs. However, its application to imaging bolus movement through the esophagus has only been demonstrated in few feasibility studies and is relatively unexplored.

EMT Participates in the Regulation of Exosomes Secretion and Function in Esophageal Cancer Cells

Technology in Cancer Research & Treatment, 2021
Epithelial-mesenchymal transition (EMT) is a key step in tumor invasion and distant metastasis. Abundant evidence has documented that exosomes can mediate EMT of tumor cells and endow them with the ability of invasion and migration.

L718Q/V mutation in exon 18 of EGFR mediates resistance to osimertinib: clinical features and treatment

Discover Oncology, 2022
Osimertinib, a mutant-specific third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), is emerging as the preferred first-line of treatment for EGFR-mutant lung cancer. However, osimertinib resistance inevitably develops
