Objective: To determine the role of fragile histidine triad (FHIT) and MDM2 in carcinogenesis of oral submucous fibrosis (OSF).

Methods: The expression of FHIT and MDM2 was examined by immunohistochemical S-P method in 44 OSF cases, 15 canceration tissues of OSF, and 10 normal oral mucosa tissues.

Results: The expression of FHIT was positive in the normal oral mucosa epithelium. The positive expression of FHIT decreased in the OSF and canceration tissues of the OSF.The rate of FHIT positive expression was significantly lower in canceration tissues of OSF than that of the OSF (P < 0.05). The expression of MDM2 was negative in normal oral mucosa epithelium. The positive expression of MDM2 increased in the OSF and canceration tissues of the OSF, and the rate of MDM2 positive expression was significantly higher in the canceration tissues of OSF than that of the OSF (P < 0.05).

Conclusion: The loss of FHIT and over-expression of MDM2 may play an important role in the carcinogenesis of OSF.

Cancer grade classification is a challenging task identified from the cell structure of healthy and abnormal tissues. The partitioner learns about the malignant cell through the grading and plans the treatment strategy accordingly. A major portion of researchers used DL models for grade classification.

Purpose: We aimed to identify the transcriptomic signatures of soft tissue sarcoma (STS) related to radioresistance and establish a model to predict radioresistance.

Materials And Methods: Nine STS cell lines were cultured. Adenosine triphosphate-based viability was determined 5 days after irradiation with 8 Gy of X-rays in a single fraction.

Background: Glioblastoma is characterized by neovascularization and diffuse infiltration into the adjacent tissue. T2*-based dynamic susceptibility contrast (DSC) MR perfusion images provide useful measurements of the biomarkers associated with tumor perfusion. This study aimed to distinguish infiltrating tumors from vasogenic edema in glioblastomas using DSC-MR perfusion images.

This study aimed to develop a novel reconstruction method for segmental mandibulectomy. In the authors' opinion, reconstruction of the anterior border of the mandibular ramus using a double-arm vascularized fibular flap is important to prevent deformity due to buccal depression and the accumulation of food debris, thereby eliminating masticatory dead space that cannot be filled with prostheses such as implants or dentures. Using conventional reconstruction plates, the reconstructed bone positioned at the anterior border of the mandibular ramus required either fixing with only 1 screw or using 2 plates for stable fixation, making it difficult to position the plates stably.
