OBJECTIVE
In magnetic fluid hyperthermia (MFH), nanoparticles are injected into diseased tissue and subjected to an alternating high frequency magnetic field. The process triggers sufficient heat to destroy the cancerous cells. One of the challenging problems during MFH is blood flow in tissue. In
We have already reported the antitumour effect of hydroxyapatite (HAP) containing anticancer drugs. In this study, we found an increased temperature effect around HAP particle(s) in an agar phantom in comparison with other areas when a Thermotron-RF8 (RF generator) was used for heating. Furthermore,
The agar double-diffusion precipitation test was applied successfully in the demonstration of ASF viral antigen in spleen and liver from swine experimentally infected by the oral route. Positive reactions were obtained with tissues collected as early as 24 hours after the onset of pyrexia and before
Magnetic nanoparticles have recently been the subject of intensive research for biomedical applications. In particular, injecting colloidal magnetic nanoparticles into the cancerous tissues and heating them by heat dissipation from magnetic nanoparticles with applying an alternating magnetic field
BACKGROUND
Magnetite used in an 8-MHz radiofrequency (RF) capacitive heating device can increase the temperature of a specific site up to 45°C. When treating a metastatic lesion around large abdominal vessels via hyperthermia with magnetite, heating-induced adverse effects on these vessels need to
Local heat generation from magnetic nanoparticles (MNPs) exposed to alternating magnetic fields can revolutionize cancer treatment. However, the application of MNPs as anticancer agents is limited by serious drawbacks. Foremost among these are the fast uptake and biodegradation of MNPs by cells and
An agar phantom with wide application in rf heating was developed. The phantom consists of 4 wt./wt. % agar powder, 0.1 wt./wt. % NaN3, 0-0.6 wt./wt. % NaCl, and 95.9-95.3 wt./wt. % water. The conductivity sigma (S/m) of the phantom was independent of frequency at 1-40 MHz, being sigma = 1.74 chi +
