purpose: to present a case of orbital granular cell tumor, a rare orbital tumor. case report: a 55-year-old woman presented with binocular diplopia and right ocular displacement. the problem had initiated 3 years ago. a firm nontender mass at the region of the right lower lid was visible. orbital ct-scan disclosed a well-defined mass in the inferior right orbit with involvement of the inferior ...

results there was no statistical difference between the 2 groups with respect to the recurrence rate (p > 0.05). although the recurrence interval was longer for the metformin group, this increase was not statistical significant (p > 0.05). furthermore, tumor recurrence had no correlation with sex or the grade of the tumors. conclusions according to our findings, it seems that metformin has no c...

Heating tumors by nanoparticles and resistance in tumor cells to a high temperature is emerging as an effective tool as nanomedicine tool in cancer therapy. The art of thermal mapping in a tumor at various locations is emerging as the selective approach of hyperthermia to monitor temperature and treat the tumor. However, thermometry and tumor cell interaction with nanoparticles may monitor and ...

Background: Radiotherapy (RT) is recommended to all patients undergoing Breast Conserving Surgery (BCS). Two strategies can be applied to irradiation, External Beam RT (EBRT) in addition, Intraoperative Radiation Therapy (IORT). The aim of this study was to introduce a protein biomarker panel related to molecular function of IORT. Materials and Methods: Six Breast Cancer (BC) patients as a pilo...

BACKGROUND AND PURPOSE CT and MR imaging features of benign and malignant sinonasal lesions are often nonspecific. Therefore, we evaluated the ADC-based differentiation of these lesions. MATERIALS AND METHODS We retrospectively assessed ADCs of 61 patients with histologically proved sinonasal tumors and tumorlike lesions: 19 benign lesions, 28 malignant tumors, and 14 inflammatory lesions. Ov...

Background and Aim: Brain mapping is a study of the anatomy and function of the CNS (central nervous system). Brain mapping has many techniques and these techniques are permanently changing and updating. From the beginning, brain mapping was invasive and for brain mapping, electrical stimulation of the exposed brain was needed. However, nowadays brain mapping does not require electrical stimula...

BACKGROUND Intraoperative brain stimulation mapping reduces permanent postoperative deficits and extends tumor removal in resective surgery for glioma patients. Successful functional mapping is assumed to depend on the surgical team's expertise. In this study, glioma resection results are quantified and compared using a novel approach, so-called resection probability maps (RPM), exemplified by ...

Thermal properties of biological tissues play a critical role in the study of tumor angiogenesis and the design and monitoring of thermal therapies. To map thermal parameters noninvasively, we propose temperature-change-based thermal tomography (TTT) that relies on relative temperature mapping using magnetic resonance imaging (MRI). Our approach is unique in two aspects: (1) the steady-state bo...
