Hybrid Odontogenic Lesion: A Rare Entity [PDF]

Journal of Dental Materials and Techniques, 2017
Hybrid tumors are very rare tumors composed of two different tumor entities, each of which conforms to an exactly defined tumor category. A 14-year-old boy was referred for an intraosseous painless lesion with a histopathological feature of multiple ...

Optical Metasurfaces for the Next‐Generation Biosensing and Bioimaging

Laser &Photonics Reviews, EarlyView.
Recent advances in this understanding of light‐matter interactions, combined with innovations in the design and fabrication of large‐scale nanostructured metasurfaces, have enabled transformative approaches to biosensing and bioimaging. This review explores innovations in refractometric sensing, surface‐enhanced spectroscopy, and super‐resolution ...

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

, 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]

arXiv, 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.

Odontogenic tumors: a 14-year retrospective study in Santa Catarina, Brazil

Brazilian Oral Research, 2014
Odontogenic tumors (OTs) are lesions that develop exclusively on maxillary bones, and form a heterogeneous group. They vary from hamartomatous lesions to benign and malign tumors.

Expression of SOX2 and OCT4 in odontogenic cysts and tumors

Head & Face Medicine, 2021
Background Aberrant expression of stem cell markers has been observed in several types of neoplasms. This trait attributes to the acquired stem-like property of tumor cells and can impact patient prognosis.

The architecture of co-culture spheroids regulates tumor invasion within a 3D extracellular matrix [PDF]

arXiv, 2020
Tumor invasion, the process by which tumor cells break away from their primary tumor and gain access to vascular systems, is an important step in cancer metastasis. Most current 3D tumor invasion assays consisted of single tumor cells embedded within an extracellular matrix (ECM). These assays taught us much of what we know today on how key biophysical

Unveiling the complex extra‐oral colonization pathways and pathogenic mechanisms of Fusobacterium nucleatum, a heterogeneous oral pathogen

VIEW, EarlyView.
We summarize the taxonomic characteristics, capabilities to adhere to and invade host cells, extra‐oral ectopic colonization pathways, and major pathogenic mechanisms of Fusobacterium nucleatum, and explore the regulation of F. nucleatum’s pathogenesis, aiming to provide references and assistance for the development of clinical interventions and future

Rigorous results of limiting behaviors of total tumor size under cyclic intermittent therapy for the system of reversible phenotype-switchable tumor cells [PDF]

arXiv, 2023
We are keenly interested in finding the limiting behaviors of total tumor size when tumor cells are subject to the periodic repetition of therapy and rest periods, called intermittent cyclic therapy. We hypothesize that each tumor cell can take either therapy-sensitive or therapy-tolerant phenotype, its phenotype transition is mainly driven by the ...
