This case report describes radiofrequency pulmonary vein isolation in a 67-year-old man with dextrocardia and situs inversus totalis. The procedure successfully isolated all pulmonary veins using 3D mapping with intracardiac echocardiography guidance. No procedural complications were reported, and the authors…

This correspondence discusses a prior ecological study examining a possible association between RF-EMF exposure in Albacete, Spain and cancer incidence. The cancers mentioned include lymphomas and brain tumors. The correspondence indicates that shortcomings of the ecological study are discussed, but does not detail…

This study reports a technology that records a specific radiofrequency electromagnetic energy signal associated with EGFR siRNA and applies it to cells. The abstract describes reductions in EGFR mRNA and protein expression versus controls, with specificity assessed using RNA microarray and antibody dot blot array. It…

This in vitro study describes a method to improve DNA ligation by immobilizing T4 DNA ligase on ferromagnetic particles and applying a radio frequency alternating magnetic field. The field causes the particles to dissipate heat, which the authors report selectively heats and activates the ligase while minimally…

This retrospective cohort study reviewed medical records from a Swedish tertiary pain centre to assess 1-month outcomes after pulsed radiofrequency for chronic non-cancer pain. Among patients receiving lumbar median branch pulsed radiofrequency, a minority had major or minor improvement, while many had no change and…

This engineering study deposited Ga-doped ZnO thin films via radio frequency sputtering and examined how Ga content affects optoelectronic properties and electrical stability. The abstract reports non-monotonic changes in conductivity with increasing Ga content alongside degraded crystallinity, while maintaining >80%…

This engineering paper demonstrates an auto-tuning method for a high-sensitivity RF interferometer using a tunable liquid attenuator controlled by liquid volume. The authors report an effective quality factor up to 1×10 at ~5 GHz and a self-calibration/measurement process from 2 to 7.5 GHz using a methanol-water…

This prospective, randomized, single-blind study compared monopolar versus bipolar radiofrequency surgery for inferior turbinate hypertrophy in 71 patients. Over 6 months, long-term symptom outcomes did not significantly differ between groups. Monopolar radiofrequency showed earlier symptom improvement and less…

This engineering study investigated RF-induced power deposition near straight insulated leads in an MRI context under different incident electric field profiles. Using 3-D electromagnetic simulations, the authors compared simulation-derived power deposition with implant model predictions. For the setups examined,…

This conference paper describes a peri-implantitis therapy using radio frequency electric current and presents numerical simulations alongside referenced clinical evidence. The abstract reports 81% successful treatment across 66 implants in 46 patients. FEM modeling suggests current preferentially concentrates in…

This engineering study investigated RF-induced power deposition from insulated leads of different lengths positioned near two surrounding tissues. The authors report that both the electromagnetic lead models and the resulting power deposition depended strongly on the electrical properties of both tissues. Using a…

This engineering study uses a 3D electromagnetic solver to simulate in-to-out body RF path loss for a wireless capsule endoscopy link. The capsule antenna is tuned for the 402 MHz MICS band while accounting for human body properties. The authors examine how capsule misalignment, rotation, and the human body model…

This engineering-focused conference paper characterizes thrombus stiffening after radio frequency (rf) electric current treatment in the context of intra-arterial mechanical thrombectomy. The abstract reports thrombus stiffness increased by more than eightfold after rf treatment, attributed to increased crosslinking.…

This single-institution cohort analysis compared radiofrequency microtenotomy with plantar fasciotomy for recalcitrant plantar fasciitis, including a group receiving both procedures. Patient-reported outcomes (SF-36, AOFAS) and satisfaction/expectations were reportedly similar across procedures at 6 months and 1…
