AI Article Synopsis
Article Abstract
Unusual ultrastructural bodies were found in about one-fifth of the epithelial cell nculei in three cases of pulmonary hamartoma. Those bodies often appear to be twisted tubules with recognizable branching. Morphologically different structures are also seen in occasional nuclei. Although the nature and significance of the bodies are obscure, they may represent different stages of development of the same structure. Similar bodies have not been encountered to date in any of our other examinations of epithelial cells.

Three-dimensional measurement of the depth of invasion in oral squamous cell carcinoma samples using Lugol's iodine-enhanced micro-computed tomography: an original study.
J Appl Oral Sci
January 2025
Nanjing University, Research Institute of Stomatology, Affiliated Hospital of Medical School, Nanjing Stomatological Hospital, Department of Oral and Maxillofacial Trauma Orthognathic Plastic Surgery, Nanjing, China.
Objectives: Depth of invasion (DOI) in oral squamous cell carcinoma (OSCC) guides treatment and prognosis but lacks three-dimensional (3D) insight. Thus, this study aimed to investigate the feasibility and accuracy of Lugol's iodine-enhanced micro-computed tomography (CT) for the 3D measurement of DOI in OSCC samples.
Methodology: In total, 50 in vitro OSCC samples from Nanjing Stomatological Hospital (July 2022 to January 2024) were subjected to micro-CT imaging with a slice thickness of 50 μm following 3% Lugol iodine staining for 12 h, followed by pathological examination and staining.
Epithelial OPA1 links mitochondrial fusion to inflammatory bowel disease.

Dysregulation at the intestinal epithelial barrier is a driver of inflammatory bowel disease (IBD). However, the molecular mechanisms of barrier failure are not well understood. Here, we demonstrate dysregulated mitochondrial fusion in intestinal epithelial cells (IECs) of patients with IBD and show that impaired fusion is sufficient to drive chronic intestinal inflammation.

Department of Oncology, Copenhagen University Hospital, Copenhagen, Denmark.
Background And Purpose: We report the incidence, characteristics, and comorbidities of the complete unselected Danish cohort of patients with thymic epitheliums (TETs), which may serve as evidence for guiding treatment, surveillance, and counselling of TET patients.
Patients And Methods: All patients diagnosed with TETs from January 1st, 2015, to December 31st, 2020, were identified using the Danish Pathology Data Registry. Data on patient characteristics, comorbidities, and tumor histology were collected from electronic medical records available for all patients.
The Transcriptomic and Gene Fusion Landscape of Pleomorphic Salivary Gland Adenomas.
Genes Chromosomes Cancer
January 2025
Sahlgrenska Center for Cancer Research, Department of Laboratory Medicine, University of Gothenburg, Gothenburg, Sweden.
Pleomorphic adenoma (PA) is the most common salivary gland tumor. PAs are characterized by chromosomal rearrangements of 8q12 and 12q14-15, leading to gene fusions involving the PLAG1 and HMGA2 oncogenes. Here, we performed the first comprehensive study of the transcriptomic and gene fusion landscape of 38 cytogenetically characterized PAs.

Background: Regulator of G protein signaling (RGS) proteins participate in tumor formation and metastasis by acting on the α-subunit of heterotrimeric G proteins. The specific effect of RGS, particularly , on the progression of gastric cancer (GC) is not yet clear.
Aim: To explore the role and underlying mechanisms of action of in GC development.
