in this paper an automatic examination robot was developed to improve the process of cancer detection, tumor localization and geometrical shape diagnosis. a uniformly distributed compressive load was applied to the top tissue surface and the resultant mechanical stress was measured that was employed for the tumor diagnosis task. the experimental examinations were performed on the soft tissue of...

needle insertion is a minimally invasive technique in diagnosing and treating tumors. however, to perform a surgery accurately, the tissue should have minimum amount of displacement during needle insertion so that it reaches the target tissue. therefore, the tissue membrane has to move less to decrease rupturing under the membrane. in this study, the effect of different design parameters on dis...

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...

Purpose The aims of this retrospective study were to evaluate the possible changes in soft tissue facial profile induced by orthopedic rapid maxillary expansion (RME) and surgically assisted rapid maxillary expansion (SARME), and to correlate them with the underlying hard tissue alterations. Materials and Methods 16 patients who received bone borne SARME and 25 patients who were subjected to ...

BACKGROUND Various shapes and designs of the gluteal artery perforator flap have been used for treating sacral pressure sores and reconstructing breasts. To establish the ideal fasciocutaneous flap design for use in the gluteal area, the soft tissue thickness distribution was measured. METHODS Twenty-one buttocks of adult Korean cadavers were analyzed through rectangular subfascial dissection...

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...

The key to achieving pleasing esthetics in implant dentistry is a thorough understanding of the biological processes driving dimensional bone and soft tissue alterations post-extraction. The aim of the present report is first to characterize the extent of bone and soft tissue changes post-extraction and second to identify potential factors influencing tissue preservation in order to facilitate ...

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-...
