This engineering/food science study examined ohmic heating of peaches at 60 V/cm using bipolar pulses across frequencies from 50 Hz to 1 MHz. Heating time to a target temperature and multiple electrical properties were frequency-dependent, particularly for intact tissue. The authors report faster electro-thermal…

This experimental study examined how pulsed electric field (PEF) processing parameters affect cell membrane rupture in onion tissue disks, using ion leakage as the primary integrity measure. Disintegration efficiency increased with field strength up to 500 V/cm and varied with pulse width, pulse number, and…

This SCENIHR Opinion updates earlier 2009 SCENIHR documents on EMF health effects and research needs, focusing on new information and remaining knowledge gaps. The abstract primarily characterizes sources and patterns of exposure across static, ELF, IF, and RF fields in both public and occupational settings. It notes…

This monocentric study evaluated outpatient feasibility and outcomes of radiofrequency transurethral needle ablation (TUNA) for benign prostatic hyperplasia in patients who did not respond to medical therapy. In the outpatient subgroup, urinary symptom scores, quality of life, flow measures, and residual urine…

This randomized controlled trial evaluated low-power, low-frequency pulsed electromagnetic field (PEMF) therapy at 600 Hz and 800 Hz as an adjunct treatment for diabetic polyneuropathy. Thirty participants were randomized to 600 Hz PEMF, 800 Hz PEMF, or usual medical treatment for 12 days. The abstract reports…

This critical review summarizes human research on static magnetic field (SMF) therapy delivered by permanent magnets attached to the skin and evaluates how well studies report SMF dosage and treatment parameters. Across 56 included studies, many did not report essential SMF characteristics (e.g., magnet dimensions,…

A meta-analysis of 63 publications assessed whether radiofrequency (RF) radiation exposure is associated with genetic damage in mammalian somatic cells using multiple genotoxicity endpoints. Overall differences between RF-exposed and control conditions were reported as small, though statistically significant…

This prospective multicenter longitudinal trial evaluated arthroscopic thermal radiofrequency capsular shrinkage for chronic ankle instability in adults who failed conservative therapy. The study reports no clinically relevant improvement in mechanical stability, but substantial and statistically significant…

This animal study examined how postoperative immobilization affects healing after radiofrequency heat probe shrinkage in rabbit patellar tendons. Tendon length increased across all groups by 8 weeks, but 4 weeks of immobilization resulted in less elongation than free activity. Immobilized groups had reduced…

This experimental physics study examines how a static electric field affects the optical nonlinearity of methyl-red doped nematic liquid crystals. The authors report that low voltages below the Fredericks transition threshold can change the optical nonlinearity by orders of magnitude. They state that the data fit a…

This Medical Physics article presents a phase-based MRI method to quantify paramagnetic contrast agent concentration by inverting susceptibility-induced magnetic field shifts, aiming to improve arterial input function (AIF) measurement in DCE-MRI. After in vitro validation, the approach was applied in vivo in 14…

This conference paper reports early development of a cell phone-based video streaming system to deliver video reminders for people with early dementia. Carers can record and schedule reminders remotely via a computer and webcam. A first prototype was implemented, with an initial field trial scheduled and a larger…

This conference paper describes a mobile-phone telemedicine system for managing chemotherapy side-effects at home using symptom diaries and automated alerts to nurses. Six patients used the system for two cycles of oral chemotherapy. The abstract reports two instances where moderate symptoms deteriorated to more…

This chemistry/engineering study reports the synthesis and NMR/MRI-relevant characterization of a trinuclear Gd(III) chelate intended for high-field MRI contrast applications. Using 17O NMR and proton relaxivity across multiple fields and temperatures, the authors infer bishydration, quantify water exchange and…

This Level III therapeutic case-control study evaluated shoulder capsule histology after arthroscopic thermal capsulorrhaphy using monopolar radiofrequency energy, with follow-up from 3.5 to 62 months. Mid- and long-term mRFE groups did not differ from controls on several histologic categories (synovial layer, edema,…

This paper describes a system intended to encourage daily walking exercise in people with COPD. During home exercise, the platform sends SMS messages to the patient's mobile phone indicating the target exercise intensity (linked to music tempo). The abstract does not report any findings about health outcomes or…

This engineering study describes development of a patch antenna array coil (PAAC) intended to address short RF wavelength challenges in ultra-high-field (≥7T) MRI. A prototype PAAC for 7T proton imaging was used to image a monkey brain. The authors report that the imaging demonstrated the coil's utility for…
