Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation

Advanced Functional Materials, EarlyView.
A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

Low-energy amplitude-modulated radiofrequency electromagnetic fields as a systemic treatment for cancer: Review and proposed mechanisms of action

Frontiers in Medical Technology, 2022
Exposure to Low-Energy Amplitude-Modulated Radiofrequency Electromagnetic Fields (LEAMRFEMF) represents a new treatment option for patients with advanced hepatocellular carcinoma (AHCC). We focus on two medical devices that modulate the amplitude of a 27.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Effects of radiofrequency electromagnetic field exposure on neurophysiology

Advances in Human Biology, 2020
The human body is a permissible medium, and radiofrequency electromagnetic field (RF-EMF) waves pass through this medium. The effects exerted by RF-EMF devices such as mobile phones on brain tissues are categorised into thermal and non-thermal effects ...

Cooling or Warming the Esophagus to Reduce Esophageal Injury During Left Atrial Ablation in the Treatment of Atrial Fibrillation. [PDF]

, 2020
Ablation of the left atrium using either radiofrequency (RF) or cryothermal energy is an effective treatment for atrial fibrillation (AF) and is the most frequent type of cardiac ablation procedure performed. Although generally safe, collateral injury to

Pulsed radiofrequency and coccygodynia [PDF]

Turkish Neurosurgery, 2015
signals via a pathway involving c-Fos, which indicates the inhibition of excitatory C fibers and long-term depression. It has also been suggested to alter gene expression in neurons by means of neuromodulation. Another popular theory is the stimulation of the serotonergic and noradrenergic system and induction of descending pathways.
