The typical radiographic appearance is very characte...
Glomangiosarcoma represents a rare malignant variant of the benign glomus tumor that typically presents as a tender, slowly growing nodule with a predilection for the lower extremities. Unlike their benign counterparts, glomangiosarcomas may display aggressive characteristics such as large size, local invasion, and a tendency to recur after excision. Although wide local excision remains the tre...
background and objectives: survival models are statistical technique to estimate or predict the overall time up to specific events. prediction is important in medical science and the accuracy of prediction is determined by a measurement, generally based on loss functions, called prediction error. the aim of this study is using parametric models to determine the factors influencing predicted sur...
This study is aimed at answering whether aging/health-related web sites of different domain extensions (i.e. .com, .edu, .gov and .org) differ in their accessibility and usability, and whether these two measures are correlated. The usability and accessibility of governmental, organizational, educational and commercial aging/health-related web sites were compared using two automatic evaluation t...

Amniotic epithelial cells (AECs) possess unique characteristics, which make them a suitable source for cell-based therapeutic strategies. AECs have stem cell properties with low-immunogenicity (due to expressing HLA-G molecule and absence of MHC class I and II antigens) and no ethical problems, as well as availability in sufficient numbers, which can be obtained from a placenta. We have recentl...
follow-up imaging of inflammatory myofibroblastic tumor of the uterus and its spontaneous regression
inflammatory myofibroblastic tumor (imt) is an aggressive benign mass that may arise from various tissues and organs with a great variability of histological and clinical appearances. due to variable and nonspecific imaging findings, diagnosis of imt is not obtained before surgery. the aim of this paper is to present ct and mri findings during four-year follow-up of complete, spontaneous regres...
