serotonin is believed as an important factor in brain function. the role of serotonin in cerebral psycho-patho-physiology has already been well established. however, the function of serotonin antagonist in anesthetized subjects under hyperthermia has not been studied properly. methods: experiments were performed in three groups of urethane-anesthetized rats, such as: (i) control group, (ii) who...

Introduction: Febrile seizures are the most common seizure disorder in childhood and its prevalence is estimated to be 2 to 5 percent. There is a relationship between the use of corticosteroids and seizures. This study investigated the effects of dexamethasone pretreatment on convulsive behavior caused by hyperthermia. Methods: In this study, 24 rats aged 19-20 days were divided into 3 group...

Introduction: Glioblastoma multiforme (GBM) is a highly radioresistant cancer with low survival rate. Current therapy approaches have failed to treat GBM. The aim of this study was to assess how GBM tumors respond to combination of hyperthermia and radiotherapy. Materials and Methods:   In this study, 38 GBM patients were included. 19 patients were treated ...

Glioblastoma is most common and most aggressive cancer of brain. for treatment surgery is first selection and radiation therapy then chemotherapy. The median survival of Patients with GBM is less than a year after diagnosis. Glioblastoma is basically resistant to common cancer treatments. today to improve the response of patients to treatment, a number of strategies such as the use of radiation...

Serotonin is believed as an important factor in brain function. The role of serotonin in cerebral psycho-patho-physiology has already been well established. However, the function of serotonin antagonist in anesthetized subjects under hyperthermia has not been studied properly. Methods: Experiments were performed in three groups of urethane-anesthetized rats, such as: (i) control group, (ii) wh...

background: a possible mechanism by which hyperthermia enhances tumor immunogenicity is the induction of nkg2d ligands on tumor cells. although the expression of mhc class i chain-related protein a and b (mica/b) has previously been reported in different carcinomas, there is no information about mica/b expression in liposarcomas. objective: to investigate mica/b induction in a human liposarcoma...

background: magnetic nanoparticles in a variable magnetic field are able to produce heat. this heat (42-45°c) has more selective effect on fast dividing cancer cells than normal tissues. methods: in this work magnetite nanoparticles have been prepared via co-precipitation and phase identification was performed by powder x-ray diffraction (xrd). magnetic parameters of the prepared nanoparticles ...

objective: in radiation treatment, the irradiation which is effective enough to control the tumors far exceeds normal-tissues tolerance. thus to avoid such unfavourable outcomes, some methods sensitizing the tumor cells to radiation are used. iododeoxyuridine (iudr) is a halogenated thymidine analogue that known to be effective as a radiosensitizer in human cancer therapy. improving the potenti...
