چکیده
There are a number of reports of the plasma membrane transport of Ca2+ in biological systems being enhanced by low frequency electromagnetic fields (EMF), including reports that the enhancement involves a resonance-type response at the cyclotron frequency for Ca2+ ions for geomagnetic values of the magnetic field. Using the fluorescent probe fura2, we find no evidence for changes in cytosolic calcium concentration in BALB/c3T3, L929, V-79, and ROS, a rat osteosarcoma cell line, at the application of both resonant and nonresonant EMF.

Pulsed electromagnetic field at frequency and intensity resembling potassium ion cyclotron resonance selectively impairs breast cancer cell through apoptosis
Introduction: Breast cancer (BC) is the most common women cancer worldwide. Radiotherapy and chemotherapy are the two common treatment options but these techniques suffer low selectivity and adverse effects on surrounding normal tissues. Non- ionizing pulsed electromagnetic fields (PEMFs) in ultra-narrow band frequency and intensity have shown anticancer effects. Changing potas...

Background: Magnetic resonance imaging (MRI) plays an essential role in molecular imaging by delivering the contrast agent into targeted cancer cells. The aim of this study was to evaluate the C595 monoclonal antibody-conjugated superparamagnetic iron oxide nanoparticles (SPIONs-C595) for the detection of breast cancer cell (MCF-7). Methods: The conjugation of monoclonal antibody and nanopartic...
متن کاملDNA Damages on Blood Cells After Cardiac Magnetic Resonance Imaging
Introduction: Along with the increased use of cardiac imaging at clinics there is increased attention to the potential risks related to the methods used like magnetic resonance (MR) and it cannot be ruled out that MR can alter DNA structure. The aim of this review is to assess the impact of routine cardiac magnetic resonance (CMR) scanning on DNA damages in human T lymphocytes....

We present an INTEGRAL observation of the Cen-Crux region in order to search the electron cyclotron resonance scattering features from the X-ray binary pulsars. During the AO1 200 ks observation, we clearly detected 4 bright X-ray binaries, 1 Seyfert Galaxy, and 4 new sources in the field of view. Especially from GX301-2, the cyclotron resonance feature is detected at about ∼ 37 keV, and width ...

Nanoparticles are unique that enable many promising medical and technological applications intheir physical, and chemical properties. It is widely accepted that nanoparticles should bethoroughly tested for health nanotoxicity, but a moderate risk analysis is currently prevented by arevealing absence of mechanistic knowledge of nanoparticle toxicity. The purpose of this study<b...
