gliosarcoma/fever

Modification of survival by long duration, 41 degrees C hyperthermia in combination with low dose rate radiation (0.5 Gy/h) was determined in rat 9L gliosarcoma cells. Cells were exposed to radiation in a manner that simulated continuous irradiation at a dose rate relevant to clinical brachytherapy.

A magnetic resonance (MR) technique is developed to produce controlled radio-frequency (RF) hyperthermia (HT) in subcutaneously-implanted 9L-gliosarcoma in Fisher rats using an MR scanner and its components; the scanner is also simultaneously used to monitor the tumour temperature and the metabolic

There are several reports of apoptosis induced by mild hyperthermia both in vitro and in vivo. However, in tumour nodules, regional differences in apoptosis induced by hyperthermia have not been studied morphologically or quantified. In this study, apoptosis was identified on the basis of its

Primary campylobacter enteritis with secondary bacteremia was diagnosed in an immunocompromised patient with stage IV gliosarcoma. She developed mild diarrhea followed by systemic symptoms with transient generalized weakness and fever. She was treated with azithromycin and had a full recovery and

OBJECTIVE Long duration-mild temperature hyperthermia has previously been shown to be an effective potentiator of low-dose-rate irradiation. An in vitro investigation was initiated to determine if 41 degrees C hyperthermia could be useful in sensitizing high-dose-rate (HDR) brachytherapy.

Clinical application of long duration hyperthermia at temperatures < 42 degrees C has traditionally been avoided because of the possibility of chronic thermotolerance development, such as is observed with rodent cells. In support of long duration hyperthermia, both rodent and human cells have been

The relative frequency of pediatric gliosarcoma (GSM) is 1.9% among glioblastomas and 0.5% among pediatric central nervous system tumors. A 5-year-old female child came to us with history of fever and loss of appetite since 2 weeks and right sided weakness since 4 days. Magnetic resonance imaging

Experimental study was made on magnetic induction hyperthermia for brain tumor using ferromagnetic implant with low Curie temperature. Thermoseed (implant) was made of nickel-palladium alloy, which was confirmed to produce enough heat by eddy current and also to have low Curie point between 43

New experimental system of induction hyperthermia for brain tumor using ferromagnetic implant with low Curie point has been developed. The metal implant is cylindrical needle and made of Fe-Pt alloy with low Curie point suitable for hyperthermia (50-60 degrees C). Induction coil and generator which

OBJECTIVE Preferential amplification of low dose-rate irradiation toxicity in tumor cells is one way of improving presently applied brachytherapy. Low temperature hyperthermia applied to a tumor volume during irradiation is one candidate for reaching this goal. The ranges of relevant temperatures

Modulated electro-hyperthermia (mEHT) is a form of hyperthermia used in the treatment of cancer. It is a variation that relies on a particular form of enhanced selectivity to enable more effective cancerous cell death yet maintaining the integrity of healthy non-cancerous cells. It is yet to

Cyclooxygenases (COX) mediate a wide variety of derangements observed during diseases of the brain. Their overexpression is involved in the mediation of inflammation, immunomodulation, blood flow, apoptosis and fever. Here, we have analyzed the localization of COX-1 and COX-2 in rat experimental

OBJECTIVE A Phase I study to determine the safety, toxicity, and maximum tolerated dose (MTD) of carmustine (BCNU) and interferon alpha-2a (IFN-a) when combined with radiation as initial therapy in high-grade glioma. METHODS Patients with newly diagnosed Grade 3 or 4 astrocytoma, oligoastrocytoma,

Malignant gliomas have been associated with a high rate of glycolytic activity which is believed necessary to sustain cellular function and integrity. Since lonidamine (LND) is believed to reduce tumor glucose utilization by inhibition of the mitochondrially-bound glycolytic enzyme hexokinase (HK),

BACKGROUND The current study was conducted to determine whether the addition of interferon-alpha (IFN-alpha) to treatment with radiation therapy and carmustine (BCNU) improves time to disease progression or overall survival in patients with high-grade glioma. METHODS Patients with anaplastic
