Magnetic fluid hyperthermia (MFH) therapy uses the magnetic component of electromagnetic fields in the radiofrequency spectrum to couple energy to magnetic nanoparticles inside tumors. In MFH therapy, magnetic fluid is injected into tumors and an alternating current (AC) magnetic flux is applied to heat the magnetic fluid- filled tumor. If the temperature(More)
We present an eddy-current test (ECT) method for detecting conductive microbeads on a nonconductive substrate. A Helmholtz coil is used to generate an exciting magnetic field. The magnetic fields, generated by eddy-currents in a Pb-Sn microbead, are detected by a spin-valve giant magnetoresistive (SV-GMR) sensor. The experimental results are compared to an(More)
In cartilaginous fish, two cDNAs encoding calcitonin-family receptors were isolated for the first time from the stingray brain. The open reading frame of one receptor cDNA coded a 525-amino acid protein. The amino acid identity of this receptor to human calcitonin-receptor-like receptor (CRLR) is 64.5%, frog CRLR is 64.7%, and flounder CRLR is 61.2% and(More)
Giant magnetoresistance (GMR) sensor has been developed and widely applied to use as magnetic read head in data storage industry. This paper describes new applications of magnetic-field measurement with high spatial-resolution and high sensitivity to nondestructive evaluation and biomedical engineering. For nondestructive evaluation, the GMR sensor, used as(More)
