recent studies show significant reduction of postural stability in transtibial amputees (ttas) especially when a perturbation is applied. however, no record has been seen on the consequences of such perturbation on the stump-socket interface pressure (ssip). our objective was to investigate whether such perturbation impose excessive pressures on the stump. we were also interested on the type of...

introduction: peripheral reactive lesions of soft tissue are common oral lesions that dentists face during routine examinations. diagnosis and development of a treatment plan is difficult if dentists are not aware of the prevalence and clinical symptoms of these lesions. the frequency of these lesions differs across various populations. the aim of this study was to determine the frequency and d...

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 (s...

Open fractures of the tibial diaphysis are often associated with severe bone and soft-tissue injury. Contamination of the fracture site and devitalization of the soft-tissue envelope greatly increase the risk of infection, nonunion, and wound complications. Management of open tibial shaft fractures begins with a thorough patient evaluation, including assessment of the bone and soft tissue surro...

Skeletal metastasis is one of the most important disabling complications of the malignant diseases. As in general, the survival of patients with osteometastatic lesions is relatively long, an early diagnosis can lead to improve the patient’s life, both quantitatively and qualitatively, and prevent exacerbation of the disease and disabling complications. In this study, 22 patients with est...

conclusions pharyngeal airway dimensions, soft palate length, thickness, and position, and hyoid position are not significantly different between skeletal class i and class ii prepubertal children. results no significant difference in the upper airway, soft palate, and hyoid variables was found between the two groups (p > 0.05) and no correlation was found between anb difference and the other v...
