background: persian gulf is a semi-closed environment which is affected by pollution ‎from heavy metals. entrance of heavy metals to the water column and binding to ‎sediment particles can affect the benthic organisms that can accumulate these ‎materials in their body. noticing this ability, mussels are considered as bio-monitoring ‎agents.‎ methods: the pearl oyster, pinctada radiate, and sedi...

recurrent dislocation is not common in small joints. this report presents a new case of chronic recurrent dislocation of proximal interphalangeal joint of the finger in which soft tissue injuries have a role in the dislocation. the patient was a 23 years old man who had referred to our center because of recurrent dislocation of proximal interphalangeal joint of his right ring finger during spor...

Objective: The aim of this study is to evaluate the effect of tissue composition on dose distribution in electron beam radiotherapy.Methods: A Siemens Primus linear accelerator and a phantom were simulated using MCNPX Monte Carlo code. In a homogeneous cylindrical phantom, six types of soft tissue and three types of tissue-equivalent materials were investigated. The tissues included muscle (ske...

tissue-engineered gingival graft was used for regenerating facial gingiva around an implant at lower left first premolar area with insufficient attached gingiva. engineered gingival graft was produced by mixing 250 ml bovine skin collagen with 250 ml nutritional medium containing human gingival fibroblasts (2×105). 3 months post-surgery, there were gains in the attached gingiva compared to pre-...

PURPOSE We have determined the ability of positron emission tomography (PET) with the thymidine analogue 3'-deoxy-3'[18F]fluorothymidine (FLT) to detect manifestation sites of bone and soft tissue tumors, to assess tumor grading, and to differentiate malignant from benign tumors. MATERIALS AND METHODS In this prospective bicenter trial, FLT-PET was done in 22 patients with established or susp...

Intramuscular myxoma is a rare benign soft tissue tumor which may be mistaken for other benign and low-grade malignant myxoid neoplasms. We present the case of a 63-year-old woman with an asymptomatic intramuscular myxoma discovered incidentally on a whole-body F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography. PET images showed a mild FDG uptake (maximum stan...

A case of benign mixed tumor of the soft tissue in a 64-year-old Japanese male is presented. He noticed a painless, elastic hard mass sized 3 cm in the right knee, which gradually grew larger and harder in the last 5 years. Magnetic resonance imaging demonstrated a mass lesion embedded in the subcutaneous tissue with low and high signal intensity at T1- and T2-weighted images, respectively. Tl-...

UNLABELLED Locally advanced soft-tissue sarcomas of an extremity can be treated either by amputation of the limb or by hyperthermic isolated limb perfusion (HILP) followed by resection of the tumor. In this study, the response to HILP was measured by PET with (18)F-fluorodeoxythymidine ((18)F-FLT). METHODS Ten patients with primary nonresectable soft-tissue sarcomas of an extremity underwent ...

The 11C-labeled tracer meta-hydroxyephedrine (11C-HED) is a noradrenaline analog that was developed to visualize the sympathetic nervous system with PET. Initial clinical studies show a rapid uptake of 11C-HED in localized tumors of this system. Whole-body imaging with 11C-HED PET is now possible as PET/CT scanners allow a rather short examination time. The aim of this study was to evaluate the...
