BACKGROUND Local hyperthermia of tumor in conjunction with chemotherapy is a promising strategy for cancer treatment. The aim of this study was to evaluate the efficacy of intratumoral delivery of clinically approved magnetic nanoparticles (MNPs) conjugated with doxorubicin to simultaneously induce magnetic hyperthermia and drug delivery in a hepatocellular carcinoma (HCC) model. MATERIALS AN...

Magnetic hyperthermia is a new type of cancer treatment designed for overcoming resistance to chemotherapy during the treatment of solid, inaccessible human tumors. The main challenge of this technology is increasing the local tumoral temperature with minimal side effects on the surrounding healthy tissue. This work consists of an in vitro study that compared the effect of hyperthermia in respo...

Hyperthermia is an experimental/adjuvant therapeutic modality for cancer. Combining hyperthermia with the non-invasive metabolic studies using magnetic resonance (MR) is an interesting area of research and can provide useful information. In this paper, feasibility of using the same radio frequency source for carrying out combined hyperthermia and MR studies is demonstrated. A conventional RF hy...

Heat therapies such as hyperthermia and thermoablation are very promising approaches in the treatment of cancer. Compared with available hyperthermia modalities, magnetic fluid hyperthermia (MFH) yields better results in uniform heating of the deeply situated tumors. In this approach, fluid consisting of superparamagnetic particles (magnetic fluid) is delivered to the tumor. An alternating (ac)...

Recent advances in nanomaterials science contributed to develop new micro- and nano-devices as potential diagnostic and therapeutic tools in the field of oncology. The synthesis of superparamagnetic nanoparticles (SPMNPs) has been intensively studied, and the use of these particles in magnetic hyperthermia therapy has demonstrated successes in treatment of cancer. However, some physical limitat...

Amphipathic polymer pullulan acetate (PA)-coated magnetic nanoparticles were prepared and characterized by various physicochemical means. The cytotoxicity and cellular uptake of the magnetic nanoparticles were examined. The hyperthermic effect of the magnetic nanoparticles on tumor cells was evaluated. Transmission electron microscopy (TEM) showed that the PA coated magnetic nanoparticles (PAMN...

Magneto-fluorescent nanocomposites of Zn doped ferrites nanoparticles with Pt complexes for magnetic hyperthermia and fluorescent imaging.

concurrent hyperthermia and radiation therapy in treatment of cancer show a strong evidence of a synergistic enhancement. we designed a new self-regulating thermo-brachytherapy seed, which serves as a source of both radiation and heat for concurrent administration of brachytherapy and hyperthermia. the thermo-brachytherapy seed has a core of ferromagnetic material which produces heat when subje...

The present study reports on the preparation and the cell viability assay of two nanoemulsions loaded with magnetic nanoparticle and chloroaluminum phthalocyanine. The preparations contain equal amount of chloroaluminum phthalocyanine (0.05 mg/mL) but different contents of magnetic nanoparticle (0.15 10 or 1.50 10 particle/mL). The human bone marrow mesenchymal stem cell line was used as the mo...
