Objective- Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF)have been well demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study,effects of SMFs on clinical and biomechanical aspects of bone healing using a canine unstable osteotomygap model were investigated .Design- Prospective descriptive trial.Animals- Fifteen mongre...

The magnetic flux density of MRI for clinical diagnosis has been increasing. However, there remains very little biological data regarding the effect of strong static magnetic fields (SMFs) on human health. To evaluate the biological effects of strong SMFs, we cultured INS-1 cells under exposure to sham and SMF conditions for 1 or 2 h, and analyzed insulin secretion, mRNA expression, cell prolif...

Authors review the importance of studying the effects of electromagnetic fields (EMF) on microcirculatory system, especially in respect of possibility that vasculature may have direct and indirect role in interaction of static magnetic fields (SMF). We outline the physiological importance of microcirculation and relatively new methods of evaluation technique in vivo and explain in details the l...

Although the promotional effects on osteoblasts of pulsed electromagnetic fields have been well-demonstrated, the effects of static magnetic fields (SMF) remain unclear; nevertheless, magnets have been clinically used as a 'force source' in various orthodontic treatments. We undertook the present investigation to study the effects of SMF on osteoblastic differentiation, proliferation, and bone ...

There is a general interest in the effects of magnetic fields on human tissue, for biomedical imaging, cancer therapy or tissue engineering applications. In particular the orthopaedic field may greatly benefit from magnetic scaffolds, magnetic fixation and magnetic delivery techniques. In this study, MG-63 osteoblast-like cells were analysed in vitro after exposure to a 320mT static magnetic fi...

Static magnetic field (SMF) therapy, applied via a permanent magnet attached to the skin, is used by people worldwide for self-care. Despite a lack of established SMF dosage and treatment regimens, multiple studies are conducted to evaluate SMF therapy effectiveness. Our objectives in conducting this review are to:(i) summarize SMF research conducted in humans; (ii) critically evaluate reportin...

An experiment was conducted at Indian Agricultural Research Institute, New Delhi to study the effect of pre-sowing seed treatment using different combinations of magnetic field intensities and time duration, on germination and seedling attributes in North Indian variety of tomato (var. Pusa Ruby). Seeds were exposed to static magnetic fields (SMF) of strength 50, 100 and 120 mT for 5, 10, 15, 2...

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 ...

A thorough assessment of the static magnetic field (SMF) inside a CO2 incubator allowed us to identify non-negligible inhomogeneities close to the floor, ceiling, walls and the door. Given that incubator's shelves are made of a non-magnetic stainless steel alloy, we did not expect any important effect of them on the SMF. Surprisingly, we did find relatively strong distortion of the SMF due to s...

Biological systems can respond to a wide range of static magnetic fields (SMF). Some of these responses seem to be mediated partly through free radical reactions. For example, in magnetic sense and navigation using the geomagnetic field, one of the most promising mechanisms for explaining magnetic compass is "a radical pair mechanism". Biological free radicals are most commonly oxygen or nitrog...
