purpose: to recognize affective factors in delivering x-ray contrast agents (which have high atomic number) via gallium carrier to liver or lymphatic neoplasm cells.   materials and methods: since uptake of gallium by liver has been reported in numerous researches, it was bonded with a contrast media (metrizoate). x-ray imaging was done to determine geometric features of liver.   results: radio...

Introduction: The global incidence of gastric cancer (GC) has been decreased dramatically in recent decades and characteristics of this cancer has been changed. Most of these changes can be resulted from changes in dietary and nutritional habits. This cancer is the most common cancer in north and northeast of Iran. In present report we will briefly summaries the gastric tumor location in a popu...

Introduction: Hydrocephaly is a common complication of intra ventricular brain tumors. The aim of this study was to determine, demographic and clinical features and type of hydrocephaly before and after surgical interventions in patients with intra ventricular brain tumor surgery. Material and methods: In a cross-sectional study, 100 patients with intra ventricular brain tumors who were candid...

Background: Bax and Bcl-2 are the major members of Bcl-2 family whose play a key role in tumor progression or inhibition of intrinsic apoptotic pathway triggered by mitochondrial dysfunction. Therefore, the balance between pro- and anti-apoptotic members of this family can determine the cellular fate. Methods: In this study, the relative level of mRNA expression of Bax and Bcl-2 genes was deter...

This is the report of a mandibular neuroectodermal/ewing sarcoma in an 8-year-old male cross breed dogthat is unique because of tumor origin location. Pedunculated, ulcerative, firm 6.0 × 4.0 × 5.5 cm tumor masseffaced the bone at the rostral part of the mandible and had a white-sanguineous color at cross sectionappearance. Histopathologically, small round blue cell tumor was diagnosed. Immunoh...

background:  giant cell tumor of tendon sheath (gctts) is often thought of as a volar finger mass. we hypothesized that gctts are equally common on the dorsal and volar aspects of the hand. in addition, we hypothesized that there are no factors associated with the location (volar versus dorsal) and largest measured dimension of a gctts.  methods:  a total of 126 patients with a pathological dia...
