BACKGROUND Hyperthermia is a common secondary insult in traumatic brain injury (TBI). The aim was to evaluate the relationship between hyperthermia and intracranial pressure (ICP), and if intracranial compliance and cerebral blood flow (CBF) pressure autoregulation affected that relationship. The relationships between hyperthermia and cerebral oximetry (BtipO2) and cerebral metabolism were also...

The adverse effects of amphetamine- (AMPH) and methamphetamine- (METH) induced hyperthermia on vasculature, peripheral organs and peripheral immune system are discussed. Hyperthermia alone does not produce amphetamine-like neurotoxicity but AMPH and METH exposures that do not produce hyperthermia (≥40°C) are minimally neurotoxic. Hyperthermia likely enhances AMPH and METH neurotoxicity directly...

The mechanisms underlying the generation of febrile seizures are poorly understood. This study investigated hyperthermia-induced changes in the hippocampus, a structure implicated in febrile seizures. It was hypothesized that neuronal excitability in the hippocampus changes with increasing temperature, and that this change is different in adult as compared with immature rats. Adult and immature...

Autocrine motility factor (AMF) plays an important role in the development of metastasis by regulating tumor cell motility. The expression of AMF is associated with metastasis in malignant musculoskeletal tumors including osteosarcoma. Recent studies indicated that hyperthermia contributes to the improvement of the prognosis of patients with soft ...

Introduction: Combining radiotherapy as one of the main modalities used for cancer treatment with other modalities such as hyperthermia has recently played a special role in reducing side effects and improving treatment outcomes. In addition, Gold nanoparticles (GNPs) have also attracted attention as suitable clinical agents for enhancing the effect of radiotherapy in treating ...

In oncology, the term 'hyperthermia' refers to the treatment of malignant diseases by administering heat in various ways. Hyperthermia is usually applied as an adjunct to an already established treatment modality (especially radiotherapy and chemotherapy), where tumor temperatures in the range of 40-43 degrees C are aspired. In several clinical phase-III trials, an improvement of both local con...

We investigated the effect of mild whole-body hyperthermia before and after 16 minutes of global cerebral ischemia on metabolic recovery during recirculation in cats using in vivo phosphorus-31 nuclear magnetic resonance spectroscopy. Hyperthermia (temperature 40.6 +/- 0.2 degrees C) was induced greater than or equal to 1 hour before ischemia and was maintained during 1.5-2 hours of recirculati...

Recently, mild hyperthermia was shown to induce cell cycle arrest at the G2/M phase transition without leading to DNA damage. The mechanism of this regulation has not yet been elucidated, although p53 has been shown to be activated in response to mild hyperthermia. Here, we report the role of thioredoxin (TXN) in mild hyperthermia-induced cellular responses. Our data showed that the protein lev...

AIM In utero irradiation models induce diffuse neuronal damage. Experimental studies have shown that hyperthermia induced seizures are easily elicited and have high mortality accompanied by neuronal loss. Neuronal damage and loss are the results of cell death coupled with cortical development in altered cellular development. The aim of the study was to investigate the changes in...

There is scientific support for the concept of a temperature set point that is, maintenance an optimal metabolic processes life depends on Nervous activity in preoptic-anterior hypothalamus brain triggers heat losing (sweating, etc.) or generating (shivering and muscle contraction, activities through stimulation autonomic nervous system. The pre-optic anterior has been shown to contain warm sen...
