Contemporary management of cancer of the oral cavity [PDF]

open access: yes, 2010
Oral cancer represents a common entity comprising a third of all head and neck malignant tumors. The options for curative treatment of oral cavity cancer have not changed significantly in the last three decades; however, the work up, the approach to ...

Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity [PDF]

open access: yes, 2017
The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities vary widely across animals. To understand this variability, we here connect nasal geometry to its function by theoretically studying the airflow and the associated scalar ...

Twelve Hour Longevity of the Oral Malodor-Neutralizing Capacity of an Oral Rinse Product Containing the Chlorine Dioxide Precursor Sodium Chlorite [PDF]

open access: yes, 2018
open access articleObjectives: The objectives of this investigation were to investigate the effectiveness and longevity of an oral rinse product containing 0.10% (w/v) of the chlorine dioxide precursor sodium chlorite (1) on oral malodor in participants ...

Fibrolipoma of the oral cavity: treatment choice in a case with an unusual location [PDF]

open access: yes, 2017
Fibro-lipoma has been infrequently found in the oral cavity. Clinical and histological features of an unusual case located alongside the lingual cortical of the mandible are reported.

Entanglement transfer between bipartite systems [PDF]

open access: yes, 2011
The problem of a controlled transfer of an entanglement initially encoded into two two-level atoms that are successively sent through two single-mode cavities is investigated. The atoms and the cavity modes form a four qubit system and we demonstrate under which conditions the initial entanglement encoded into the atoms can be completely transferred to

Simultaneous Nuclear Instance and Layer Segmentation in Oral Epithelial Dysplasia [PDF]

open access: yesarXiv, 2021
Oral epithelial dysplasia (OED) is a pre-malignant histopathological diagnosis given to lesions of the oral cavity. Predicting OED grade or whether a case will transition to malignancy is critical for early detection and appropriate treatment. OED typically begins in the lower third of the epithelium before progressing upwards with grade severity, thus

Would You Recognize Lupus? [PDF]

open access: yes, 2018
Systemic Lupus Erythematosus, or SLE, is a chronic autoimmune disease which significantly affects various organs of the body and the oral cavity. According to various studies, SLE can cause an increased risk of periodontitis, fungal infections, and ...

From 2D to 3D gamma passing rate tolerance and action limits for patient‐specific quality assurance in volumetric‐modulated arc therapy

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Volumetric modulated arc therapy (VMAT) requires an accurate patient‐specific quality assurance (PSQA) program. In clinical practice, this is usually performed using the γ‐index and the two‐dimensional gamma passing rate (2D %GP). A three‐dimensional (3D) index incorporating the patient anatomy could be more useful for the 3D dose ...

Oral cancer detection and interpretation: Deep multiple instance learning versus conventional deep single instance learning [PDF]

open access: yesarXiv, 2022
The current medical standard for setting an oral cancer (OC) diagnosis is histological examination of a tissue sample from the oral cavity. This process is time consuming and more invasive than an alternative approach of acquiring a brush sample followed by cytological analysis.

Laser spectroscopy of gas confined in nanoporous materials [PDF]

open access: yesApplied Physics Letters 96, 021107 (2010), 2009
We show that high-resolution laser spectroscopy can probe surface interactions of gas confined in nano-cavities of porous materials. We report on strong line broadening and unfamiliar lineshapes due to tight confinement, as well as signal enhancement due to multiple photon scattering. This new domain of laser spectroscopy constitute a challenge for the
