Effects of heat treatment, with and without an external magnetic field, on the magnetic properties of Fe81B15Si4 amorphous specimens are investigated by Lorentz microscopy and electron holography. These observations are used to clarify the details of magnetizing processes in the specimens. It is found that heat-treatment with an external magnetic field increases the magnetic anisotropy, while t...

Whilst the antidepressant properties of repetitive transcranial magnetic stimulation treatment (rTMS) have been repeatedly demonstrated, minimal research has investigated the use of rTMS to prevent relapse in patients who have responded to treatment. To address this issue, a large open label trial of a new form of clustered maintenance rTMS was conducted. Thirty-five patients with treatment res...

This work aims to demonstrate the need for in silico design via numerical simulation to produce optimal Fe3O4-based magnetic nanoparticles (MNPs) for magnetic hyperthermia by minimizing the impact of intracellular environments on heating efficiency. By including the relevant magnetic parameters, such as magnetic anisotropy and dipolar interactions, into a numerical model, the heating efficiency...

Low back pain is estimated to affect 80% of the general population at least once in their lifetime. It is the fifth leading cause of medical clinic visits and the leading work-related disability. Lumbar discography has been used to diagnose the source of low back pain when non-invasive imaging, such as magnetic resonance (MR), does not reveal morphologic abnormality consistent with symptoms. Co...

The effects of magnetic fields (MF) on germination and early growth parameters, redox state and the activity of antioxidant system were investigated in soybean (Glycine max L. Merrill) seedlings. The seeds were imbibed in water and then were exposed to a 30 mT static magnetic field (SMF) and a 10 kHz electromagnetic field (EMF) for 4 days, each 5 h. Water uptake of seeds increased after 40 and ...

Introduction: In recent years, the use of magnetic resonance (MR) images in radiation treatment planning has drawn considerable attention. However, although the extent of a tumor can be determined in great detail on MR images, the geometric accuracy of these images is limited by distortions stemming from the inhomogeneity of the static background magnetic field, the nonlineari...

introcduction: pigmented villonodular synovitis (pvs) is rare, benign and proliferative disorder of synovium which consists of villous and/ or nodular formations in joints.diagnosis is determined by clinical features, aspiration of the joint, radiographic features and magnetic resonance imaging (mri).the definitive treatment is the complete resection of affected tissue by open or arthroscopic s...
