Atomic magnetometers (AM)—also known as optical magnetometers—were introduced inthe late 1950’s. In the past 15 years AM R&D; has received a new boost owing to theimplementation of laser light for the AM operation. AM currently represent the mostsensitive magnetometers and typically allow the detection of magnetic field changes inthe one-digit femto-Tesla range (to note that ...

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 increasing number of scientific publications focusing on magnetic materials indicates growing interest in the broader scientific community. Substantial progress was made in the synthesis of magnetic materials of desired size, morphology, chemical composition, and surface chemistry. Physical and chemical stability of magnetic materials is acquired by the coating. Moreover, surface layers of ...

background: back pain is a common patients’ complaint, and its etiology is important because of different potential treatment approaches (based on causes). for a better diagnosis, magnetic resonance imaging (mri) is widely used in clinical settings that may result in inappropriate requests. this study aims to evaluate the appropriateness of the lumbosacral mri requests in patients with back pai...

purpose this study was performed to introduce and evaluate the potential of kinematic magnetic resonance imaging (kmri) using a high-field open-magnet magnetic resonance (mr) system. methods we attempted to perform kmri of healthy volunteers’ lumbar spine and knee in the lateral position and ankle in the supine position utilizing the superconducting, horizontally opened, 1.2 t mr system (oasis,...

Magnetic hyperthermia ablation has attracted wide attention in tumor therapy for its minimal invasion. Although the chemo-hyperthermal synergism has been proven to be effective in subcutaneously xenografted tumors of nude mice in our previous experiment, the occurrence of residual tumors due to incomplete ablation is more common in relatively larger and deeper-seated tumors in anti-tumor therap...

PURPOSE To explore the thermoresistance and expression of heat-shock protein 90 (HSP90) in magnetic hyperthermia-treated human liver cancer stem-like cells (LCSCs) and the effects of a heat-shock protein HSP90 inhibitor 17-allylamino-17-demethoxgeldanamycin (17-AAG) on hepatocellular carcinoma-burdened nude mice. METHODS CD90(+) LCSCs were isolated by magnetic-activated cell sorting from BEL-...

Staphylococcus aureus is a common hospital and household pathogen. Given the emergence of antibiotic-resistant derivatives of this pathogen resulting from the use of antibiotics as general treatment, development of alternative therapeutic strategies is urgently needed. Here, we assess the feasibility of killing S. aureus cells in vitro and in vivo through magnetic hyperthermia mediated by magne...

Among a variety of hyperthermia methods, magnetic nanoparticle hyperthermia is a highly promising approach for its confined heating within the tumour. In this study we perform in vivo animal experiments on implanted prostatic tumours in mice to measure temperature distribution in the tumour during magnetic nanoparticle hyperthermia. Temperature elevations are induced by a commercially available...

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...
