This prospective clinical and radiological study evaluated radiofrequency kyphoplasty in 25 patients with 30 fresh osteoporotic vertebral fractures. Pain scores decreased significantly postoperatively and at 3 months, and vertebral height/kyphosis measures improved and remained stable at follow-up. The authors report…

This engineering-focused study evaluates pulsed electric field (PEF)-assisted, solvent-free modification of pectin from sugar beet pulp. The authors report that degree of esterification increased with greater PEF intensity and energy input, with supporting evidence from FT-IR, X-ray diffraction, and NMR. Modified…

This paper describes development and testing of a Wi-Fi–enabled tele-localisation prototype for radiotherapy field localisation using a personal digital assistant (PDA). Trial tests on 30 subjects across multiple treatment regions reported localisation times under 1.5 minutes and similar transmission speeds across…

This observational study followed 36 patients for 2 years after temperature-controlled radiofrequency tissue volume reduction for turbinate hypertrophy. Patients reported significantly lower VAS symptom scores (nasal obstruction, headache, rhinorrhoea, anosmia) after treatment compared with baseline. Urban residence…

This experimental animal study evaluated whether a radiofrequency method could induce thrombosis within an abdominal aortic aneurysm sac to potentially prevent endoleaks after endovascular repair. Six dogs received radiofrequency blood clotting of the sac and then stent-grafting, compared with a historical group of…

This engineering paper describes a mm-scale implantable device that is wirelessly powered and remotely controlled to locomote in a fluid medium. The prototype is reported to receive 500 µW from a 2 W, 1.86 GHz RF power signal at 5 cm and to support 2.5–25 Mbps data rates using asynchronous PWM on the carrier. The…

This article describes a surgical technique for arthroscopic capsular release in adhesive capsulitis using a flexible hip arthroscopy radiofrequency ablator. The authors present it as a creative approach intended to improve safety and precision in a procedure that can be technically challenging. The abstract does not…

This preliminary clinical series evaluated radiofrequency-assisted recanalization of the nasolacrimal duct in adults with confirmed lower lacrimal system obstruction. The procedure used a monopolar high-frequency device at 450 kHz and 150 W under local anesthesia with sedation. At 90 days postoperatively, 81.25% of…

This physics study analyzes circular wave packets in high Rydberg states produced by applying a pulsed electric field to extreme Stark states. It reports a position-dependent energy gradient that creates a correlation between principal quantum number and spatial coordinate, which appears insensitive to the initial…

This animal experiment assessed integral and pulsed bioelectric activity across rabbit brain regions during exposure to low-intensity magnetic and electromagnetic fields. The authors report that brain-region participation in CNS reactions varied across exposure parameters and conditions and depended strongly on…

This paper describes an engineering device for wireless microscopy using a mobile phone and a WiFi system. The system allows recording, displaying, and storing microscopic images from a remote end via wireless LAN. Conceptual demonstrations are reported for monitoring common objects and liver cancer cells, with…

This experimental study investigated evaporation of pure water placed at different simulated gravity positions within a superconducting magnet producing a large gradient magnetic field. Water evaporation was reported to be faster in the magnetic field than without the field, and the amount evaporated varied by…

This animal and in vitro study evaluated nanosecond pulsed electric fields (nsPEF) as a nonchemical method to activate platelet-rich plasma (PRP) for cardioprotection. In rabbits undergoing brief coronary occlusion followed by reperfusion, PRP injection into ischemic myocardium was associated with reduced infarct…

This paper proposes that Pb nanowires created by repeated indentation of a Pb tip on a Pb substrate may exhibit topological superconducting properties in an external magnetic field. The authors analyzed conductance curves from different nanowires and report that, in a few cases, the critical current shows a peculiar…

This paper reports the scientific basis and 2D electromagnetic particle-in-cell simulation results for magnetizing an initially unmagnetized plasma using beat-wave current drive. Simulations across different angles between injected waves show beat-wave generation consistent with theoretical predictions and reveal…

This engineering study evaluated long-term encapsulation and packaging reliability of a fully wireless 100-channel Utah Slant Electrode Array system in vitro. The device was soaked in PBS for over 12 months while being wirelessly powered/configured at 2.765 MHz and transmitting an FSK-modulated 900 MHz RF signal. The…

This study evaluated mobile phone use as a tool to improve cancer care follow-up and communication in a low-resource Nigerian setting. Among 1176 oncology patients, sustained follow-up at 24 months was reported as much higher in those receiving the phone intervention than in those who did not. Patients also reported…

This paper describes an engineering/clinical tool development effort: the Robotic EndoLaryngeal Flexible (Robo-ELF) Scope System for manipulating flexible endoscopes in laryngeal surgery. The system includes multiple degrees of freedom, a passive positioning arm, and a custom joystick controller enabling one-handed…

This randomized, placebo-controlled, double-blind, cross-over trial evaluated a wrist-applied PEMF bracelet in 18 migraine patients and examined possible modulation of placebo effects. In the overall group, both PEMF and placebo were associated with similar reductions in migraine frequency and intensity. The authors…

This study investigates instrumentation and procedures to assess electromagnetic exposure from compact fluorescent lamps (CFLs) by measuring both incident and induced fields in the 10 kHz–1 MHz range. For some CFLs, incident electric fields exceeded ICNIRP reference levels at close distances, but induced fields were…
