expensive to provide these maps with field measurements therefore it is better to use new methods. this study provides a lithological and alteration mapping units with dominant minerals based on hyperspectral images of eo1-hyperion satellite. to do so, two different zones were investigated: the cuprite-nevada and mozahem volcano in iran which have suitable conditions for our study...
Multiple myeloma (MM), a malignancy of plasma cells, is characterized by widespread genomic heterogeneity and, consequently, differences in disease progression and drug response. Although recent large-scale sequencing studies have greatly improved our understanding of MM genomes, our knowledge about genomic structural variation in MM is attenuated due to the limitations of commonly used sequenc...
introduction: a keratocystic odontogenic tumor is a benign intra-bone mass originating from dental lamina or its residue. it represents 2–11% of jaw cysts, and has a slow but aggressive growth. the evaluation of molecular characteristics, immunohistochemistry, and genetic expression currently have no established classification regarding the evolution and pathophysiologic pattern of these lesion...
conclusions pnet/ews should be included in the differential diagnosis of renal tumors in symptomatic young adults. patients with localised pnet/ews treated with a combination of surgery and chemotherapy have an excellent chance of long-term survival, as in the case we have presented. introduction primitive neuroectodermal tumor (pnet)/ewing’s sarcoma (ews) belongs to a family of neoplasms that ...
Objective—To describe initial experience with resting state correlation mapping as a potential aid for presurgical planning of brain tumor resections. Methods/Technique—Resting state blood oxygenation dependent (BOLD) fMRI was acquired in seventeen healthy young adults and four patients with brain tumors invading sensorimotor cortex. Conventional fMRI motor mapping (finger tapping protocol) was...
introduction:neurogenic mediastinal tumors comprise a wide range of benign and malignant diseases. a group of these tumors, located at thoracic apex, sometimes spread to cervical spaces causing numerous surgical difficulties. in thoracotomy approaches, due to proximity of the tumors to major blood vessels, complete removal of these tumors from cervical spaces is impossible or may cause intraope...
introduction: different imaging modalities are used to evaluate salivary gland diseases, including tumors. ultrasonography (us) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. the aim of this study was to evaluate the role of us in differentiating malignant from benign parotid tumors, in the context of previous controversy...
introduction: notochord. although histologically benign, these tumors are locally aggressiveand present significant managment challenges . there arew some studies onevaluated the location, age and gender of the patients with chordoma in tworeferral centers in tehran.chordoma cases but there was no study about iranian cases. in this study weskull base chordomas are rare neoplasms arising from th...
