The role of active oxygen species and lipid peroxidation in the antituiiuir effect of hyperthermia was studied in an experimental rabbit model. VX2 tumors were transplanted Into rabbit hind legs, and the effect of hyperthermia on tumor growth was measured at 7 and 14 days after heating. As an index of lipid peroxidation, thiobarbituric acid-reactive substances in the tumor tissue were measured ...

The blood-brain/tumor barrier inhibits the uptake and accumulation of chemotherapeutic drugs. Hyperthermia can enhance the delivery of chemotherapeutic agent into tumors. In this study, we investigated the effects of short-time focused ultrasound (FUS) hyperthermia on the delivery and therapeutic efficacy of pegylated liposomal doxorubicin (PLD) for brain metastasis of breast cancer. Murine bre...

A combination of hyperthermia with radiotherapy and chemotherapy for various solid tumors has been practiced clinically. However, hyperthermic therapy has side effects, such as thrombocytopenia. Up to now, the pathogenesis of hyperthermia-induced thrombocytopenia remains unclear. Previous studies have shown that hyperthermia induces platelet apoptosis. However, the signaling pathways and molecu...

In this thesis a theoretical investigation to a new head and neck hyperthermia applicator is described. This project forms the first step towards the development of a head and neck hyperthermia treatment system. Hyperthermia is defined as a temperature elevation by several degrees (3-TC) above the normal physiological level. A hyperthermia cancer treatment aims to kill cancerous cells by delibe...

BACKGROUND AND PURPOSE Experimental studies have shown that hyperthermia is a determinant of poor outcome after ischemic stroke. Clinical studies evaluating the effect of temperature on poststroke outcome have, however, been limited by small sample sizes. We sought to evaluate the effect of temperature and timing of hyperthermia on outcome after ischemic stroke. METHODS Data of 5305 patients ...

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 groups (...

BACKGROUND In the care of patients with traumatic injuries, focus is placed on hypothermia secondary to its deleterious impact on the coagulation cascade. However, there is scant information on the mortality effect of hyperthermia. STUDY OBJECTIVES We hypothesized that both hypothermia and hyperthermia are associated with decreased survival in patients with traumatic injuries. Furthermore, we...

BACKGROUND Locoregional hyperthermia combined with radiotherapy significantly improves locoregional control and overall survival for cervical tumors compared to radiotherapy alone. In this study biological modelling is applied to quantify the effect of radiosensitization for three cervical cancer patients to evaluate the improvement in equivalent dose for the combination treatment with radiothe...
