The mitochondria isolated in isotonic sucrose from AH-130 Yoshida ascites hepatoma appear spontaneously swollen (11, 12). This spontaneous swelling may be in part responsible for the inability of tumor mitochondria to undergo extensive volume changes in hypotonie conditions or in conditions that induce large-amplitude, metabolic-dependent, or metabolic-independent swelling in normal liver mitoc...

Physical measurement of tumor volume reduction is the most commonly used approach to assess tumor progression and treatment efficacy in mouse tumor models. However, it is relatively insensitive, and often requires long treatment courses to achieve gross physical tumor destruction. As alternatives, several non-invasive imaging methods such as bioluminescence imaging (BLI), fluorescence imaging (...

UNLABELLED By allowing simultaneous measurements of tumor volume and metabolic activity, integrated PET/CT opens up new approaches for assessing tumor response to therapy. The aim of this study was to determine whether combined assessment of tumor volume and metabolic activity improves the accuracy of (18)F-FDG PET for predicting histopathologic tumor response in patients with soft-tissue sarco...

BACKGROUND The purpose of this study is to investigate whether (18)F-fluorodeoxyglucose (FDG) micro-positron emission tomography-computed tomography (microPET-CT) can be used to monitor a metabolic response to gefitinib in nude mouse tumor xenografts. METHODS Sixteen nude mice were implanted with human A431 epidermoid carcinoma cells and ten with human A549 lung adenocarcinoma cells, and the ...

Significance Through the use of different in silico modeling approaches capturing tumor heterogeneity, we postulated that areas high metabolic activity would shift toward periphery as tumors become more aggressive. To confirm hypothesis and provide clinical value for finding, collected 18 F-FDG PET images breast cancers non–small-cell lung cancers, where measured distance from point maximum to ...

Introduction: Transient cavitations induced by low frequency irradiation of ultrasound can be used to treat tumors. Previous studies in in-vitro experiments have shown that induced cavitation by dual or multiple frequencies of ultrasound is greater than induced cavitation by single frequency irradiation. In this study, we compared and evaluated the treatment effects of dual frequency irradiatio...

Radiation therapy is an important component of cancer therapy for early stage as well as locally advanced lung cancer. The use of F18 FDG PET/CT has come to the forefront of lung cancer staging and overall treatment decision-making. FDG PET/CT parameters such as standard uptake value and metabolic tumor volume provide important prognostic and predictive information in lung cancer. Importantly, ...
