Background. The aim of this study was to determine the tumor blood flow modifying, and potential vascular targeted effect of electrochemotherapy with bleomycin or cisplatin. Materials and methods. Electrochemotherapy was performed by application of short intense electric pulses to the tumors after systemic administration of bleomycin or cisplatin. Evaluated were antitumor effectiveness of elect...

Prolactin-secreting pituitary tumors are now recognized as a common endocrinologic problem [1]. Bromocriptine is an ergot alkaloid which, by virtue of its agonist action at the dopamine receptor, is effective in lowering serum prolactin levels [2). Although a number of reports have shown reduction in tumor size with bromocriptine therapy [3-8], documentation of rapid regression of tumor size is...

t regulatory cells play a crucial role in immunological unresponsiveness to self- antigens and in suppressing excessive immune responses deleterious to the host. t regulatory cells are produced in the thymus as a functionally mature subpopulation of t cells. they can be induced from naive t cells in the periphery and express their marker as a forkhead/winged helix transcription factor called fo...

we report the case of a 54-year-old iranian man who presented with melena from three months prior to admission. esophagogastroduodenoscopy and colonoscopy were normal. double balloon enteroscopy showed a pedunculated tumor located in the jejunum. he underwent laparotomy and resection of a 9.5 cm tumor from the distal jejunum. histopathologic evaluation confirmed the diagnosis of an inflammatory...

background: wilms' tumor is an emberyonal tumor arising from remnants of immature renal tissue. her2/neu is an onco-protein which mediates cellular proliferation, differentiation and survival. methods: in the current study, we analyzed her2/neu expression in 40 wilms' tumors. the clinico-demographic data of 40 patients with wilms' tumor were retrieved. immunohistochemical staining for her2/neu ...

the majority of osseous tumors of the hand are benign. the surgeon who evaluates and treats osseous tumors of the hand has to be familiar with limb anatomy, tumor biology, various presentations of the tumors and the range of treatment possibilities and their limitations. lesions in the hand more often present earlier in their course than those at other sites, just because they are more likely t...

BACKGROUND The purpose of this study was to investigate the effect of infliximab, an anti-tumor necrosis factor α (TNFα) monoclonal antibody, on the progression of cachexia and several metabolic parameters affected by the Walker-256 tumor in rats. METHODS Infliximab (0.5 mg/kg) was ip administered, twice a day, beginning at the day in which the Walker-256 tumor cells were inoculated. After 12...

Among brain tumors, glioblastoma multiforme appears as one of the most aggressive forms of cancer with poor prognosis and no curative treatment available. Recently, a new kind of radio-chemotherapy has been developed using synchrotron irradiation for the photoactivation of molecules with high-Z elements such as cisplatin (PAT-Plat). This protocol showed a cure of 33% of rats bearing the F98 gli...
