We present a biocompatible, all-glass, 0.2 mm diameter, fiber-optic probe that combines an extrinsic Fabry-Perot interferometry and a proximal fiber Bragg grating sensor; the probe enables dual pressure and temperature measurement on an active 4 mm length, with 40 Pa and 0.2°C nominal accuracy. The sensing system has been applied to monitor online the radiofrequency thermal ablation of tumors i...

BACKGROUND Capacitive radiofrequency (RF) hyperthermia suffers from excessive temperature rise near the electrodes and poorly localized heat transfer to the deep-seated tumor region even though it is known to have potential to cure ill-conditioned tumors. To better localize heat transfer to the deep-seated target region in which electrical conductivity is elevated by nanoparticle mediation, two...

This paper presents the test results of a radiofrequency (RF) plasma generator, developed for neutral beam injectors. A water cooled faraday screen is installed into generator multi-second pulse operation. Consistent operation achieved 20-second long pulses with input power 38 kW described. The density ion current was measured. experiments were conducted to measure at driver’s output and evalua...

THE search for treatments that relieve chronic pain is expanding and includes biobehavioral techniques, the discovery of new drugs, novel routes of drug administration, neuroablative treatments, and innovative surgical procedures. The use of less invasive, interventional strategies for chronic pain relief has gained popularity since the publication of evidence from randomized controlled trials....

BACKGROUND Temperature sensitive liposomes (TSL) are nanoparticles that rapidly release the contained drug at hyperthermic temperatures, typically above ~40°C. TSL have been combined with various heating modalities, but there is no consensus on required hyperthermia duration or ideal timing of heating relative to TSL administration. The goal of this study was to determine changes in drug uptake...

Loco-regional treatments play a key role in the management of hepatocellular carcino‐ ma (HCC). Image-guided tumor ablation is recommended in patients with early-stage HCC when surgical options are precluded. Radiofrequency ablation is currently es‐ tablished as the standard method for local tumor treatment. Despite major advances in tumor ablation techniques the disease recurs in a high propor...

Abstract Ni60Co40 nanoparticles supported on ?-Al2O3 capable of simultaneously catalysing the steam reforming reaction methane and supplying in-situ heat necessary to activate by induction heating, have been synthesized characterized. Energy is remotely promptly supplied an alternating radiofrequency magnetic field (induction heating system) that act as dissipating agents virtue their ferromagn...
