Objective: To examine the nasopalatine canal (NPC) anatomical and volumetric measurements in anterior edentulous (AE) and anterior dentate (AD) individuals and to compare these findings according to sex, age, shape, and severity of resorption in the premaxilla.
Methods: Two hundred cone beam computed tomography images were divided into 2 groups: AE and AD. The diameter, the length of the NPC and the width, the length of the buccal bone anterior to the NPC were measured and recorded. Linear and volumetric measurement results were evaluated in terms of age, sex, dental status, shape, and severity of resorption.
Results: No significant differences were observed between the AE and AD groups in terms of the NPC volume (P = 0.289). In the AE group, the spindle shape had the highest volume, and in the same group, with aging, the volume significantly increased (P = 0.00). The mean NPC volume was found to be statistically significantly larger in males than females (P = 0.02). A statistically significant relation was observed between NPC volume and resorption status.
Conclusion: Severe bone resorption due to sustained edentation complicated implant surgery because of the increase in incisive and nasal foramen diameters and decrease in buccal residual bone dimensions. The NPC volume was found fewer in edentulous patients, and by the resorption, the volume was decreased.

Background And Purpose: Radiation-induced hypothyroidism (RIHT) is a late complication of intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC). We evaluated thyroid protection in NPC patients receiving IMRT using modified delineation (MD) of cervical lymphatic drainage areas, sparing the common carotid artery within the clinical target volume (CTV), to assess its impact on thyroid function and survival outcomes.
Materials And Methods: This retrospective cohort study included patients without metastatic lymph nodes at levels III and IV who received neck irradiation.

Radiation therapy is a primary and effective treatment strategy for NasoPharyngeal Carcinoma (NPC). The precise delineation of Gross Tumor Volumes (GTVs) and Organs-At-Risk (OARs) is crucial in radiation treatment, directly impacting patient prognosis. Despite that deep learning has achieved remarkable performance on various medical image segmentation tasks, its performance on OARs and GTVs of NPC is still limited, and high-quality benchmark datasets on this task are highly desirable for model development and evaluation.

Changing environmental conditions necessitate rapid adaptation of cytoplasmic and nuclear volumes. We use the slime mold Dictyostelium discoideum, known for its ability to tolerate extreme changes in osmolarity, to assess which role nuclear pore complexes (NPCs) play in achieving nuclear volume adaptation and relieving mechanical stress. We capitalize on the unique properties of D.

Background: This study investigates the impact of convergence mode (CM) in Eclipse (Varian Medical Systems) on the quality and complexity of volumetric modulated arc therapy (VMAT) plans for nasopharyngeal carcinoma (NPC) patients.
Methods: We retrospectively analyzed data from 21 NPC patients. For each patient, three VMAT plans with different CM settings (Off, On, and Extended) were created using identical optimization objectives.

Article Synopsis
- The study aimed to assess how well different models predict radiation-induced oral mucositis (RIOM) in nasopharyngeal carcinoma patients after radiotherapy.
- Data was collected from 198 NPC patients who experienced RIOM, using various classification models that combined clinical data and radiation dose information.
- The H-MCF model, which merged multiple types of data, outperformed other models with a high accuracy of 85% and strong sensitivity and specificity, suggesting it is effective in predicting severe RIOM.
