Clinical and demographic characteristics of adenomatoid odontogenic tumors: analysis of 116 new cases from a single center

open access: yesBrazilian Journal of Otorhinolaryngology, 2022
Introduction: The adenomatoid odontogenic tumor is a relatively uncommon odontogenic neoplasm representing about 4.7% of all odontogenic tumors. Objective: The aim of this study was to determine the demographic and clinical profile of the adenomatoid ...

Brain Tumors Classification for MR images based on Attention Guided Deep Learning Model [PDF]

open access: yesarXiv, 2021
In the clinical diagnosis and treatment of brain tumors, manual image reading consumes a lot of energy and time. In recent years, the automatic tumor classification technology based on deep learning has entered people's field of vision. Brain tumors can be divided into primary and secondary intracranial tumors according to their source. However, to our

Synthetic Tumors Make AI Segment Tumors Better [PDF]

open access: yesarXiv, 2022
We develop a novel strategy to generate synthetic tumors. Unlike existing works, the tumors generated by our strategy have two intriguing advantages: (1) realistic in shape and texture, which even medical professionals can confuse with real tumors; (2) effective for AI model training, which can perform liver tumor segmentation similarly to a model ...

Molecular Profiling of Odontogenic Tumors - Pilot Study

open access: yesBalkan Journal of Dental Medicine, 2017
Background/Aim: In the pathogenesis of odontogenic tumors which arise from the rests of the dental apparatus in the jaw, several molecular pathways have been shown to play critical roles such as genetic alterations in the hedgehog, BRAF/Ras/MAPK ...

Label-Free Liver Tumor Segmentation [PDF]

open access: yesarXiv, 2023
We demonstrate that AI models can accurately segment liver tumors without the need for manual annotation by using synthetic tumors in CT scans. Our synthetic tumors have two intriguing advantages: (I) realistic in shape and texture, which even medical professionals can confuse with real tumors; (II) effective for training AI models, which can perform ...

The evolving molecular characterisation, histological criteria and nomenclature of adenoid ameloblastoma as a World Health Organisation tumour type

open access: yesHistopathology, Volume 85, Issue 6, Page 846-852, December 2024.
Adenoid ameloblastoma has been recently defined as a distinct odontogenic tumour type by the World Health Organisation. However, its essential and desirable diagnostic criteria are relatively non‐specific and there are overlapping morphological and molecular features with other odontogenic tumour types.

Elastic free energy drives the shape of prevascular solid tumors [PDF]

open access: yes, 2014
It is well established that the mechanical environment influences cell functions in health and disease. Here, we address how the mechanical environment influences tumor growth, in particular, the shape of solid tumors. In an in vitro tumor model, which isolates mechanical interactions between tumor cells and a hydrogel, we find that tumors grow as ...

Tumor growth with nutrients: stability of the tumor patches [PDF]

open access: yesarXiv, 2022
In this paper, we study a tumor growth model with nutrients. The contact inhibition for the tumor cells, presented in the model, results in the evolution of a congested tumor patch. We study the regularity of the tumor patch as the nutrients' diffusion strength $D$ diminishes.

Benign lesions of the mediastinum

open access: yesHistopathology, Volume 84, Issue 1, Page 183-195, January 2024.
Thymic hyperplasia with lymphoepithelial sialadenitis (LESA)‐like features as an example of a thymic tumorous lesion showing an association with non‐myasthenic autoimmune diseases and lymphomas. Mediastinal tumours represent a heterogeneous group of entities derived from the manifold structures located in or adjacent to the mediastinum.

The Interrelationship of Adenomatoid Odontogenic Tumour and Dentigerous Cyst: A Report of a Rare Case and Review of the Literature

open access: yesCase Reports in Pathology, 2012
The adenomatoid odontogenic tumor (AOT) is a relatively uncommon lesion which mainly affects females in their second decade of life, exhibiting predilection for the anterior region of the maxilla.
