Feasibility of carbon‐ion radiotherapy for oral non‐squamous cell carcinomas

Comparative evaluation of the frequency of myofibroblasts between oral and cutaneous squamous cell carcinomas

Introduction: Differentiation of fibroblasts to myofibroblasts is an initial and very important event in tumor genesis. Myofibroblasts produce proteinases that stimulate invasion in cancers. Due to the more malignant potential of oral squamous cell carcinoma (OSCC) compared to cutaneous squamous cell carcinoma (CSCC) , the aim of the present study was to compare myofibroblasts between OSCC and ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Primary Oral Squamous Cell Carcinomas

Oral squamous cell carcinomas stimulate osteoclast differentiation.

Matrix metalloproteinases (MMPs) play important roles in the invasion and metastasis to soft tissues of carcinomas including, oral squamous cell carcinomas (SCCs). Although, osteoclastic bone resorption is an important step in bone involvement in a variety of malignancies, the mechanism of bone involvement of oral SCC remains unclear. Once cancer cells arrest in bone, the bone is a storehouse o...

A fast model for prediction of respiratory lung motion for image-guided radiotherapy: A feasibility study

Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...
