This paper reports the isolation of strain M26 from garden soil that was pre-treated with microwave radiation, followed by polyphasic taxonomic characterization. Based on morphological, chemotaxonomic, and 16S rRNA phylogenetic analyses, the authors propose the new species Streptosporangium minutum. The strain is…

This article describes a signal-processing/measurement concept in pulsed magnetic resonance: achieving phase cycling through sinusoidal magnetic field modulation rather than changing pulse phases. The abstract states that modulation parameters can control spin precession phases, enabling separation of unwanted…

This study developed a mathematical and computer simulation model to analyze RF-EMF exposure in a human head phantom, motivated by potential therapeutic applications. The modeled exposure used a Yagi-Uda antenna at 64 MHz with SAR 0.6 W/kg and compared field distribution using one versus four antennas. COMSOL Bioheat…

This in vitro study examined rat adipose-derived mesenchymal stem cells exposed to zinc sulphate in the presence of an ELF electromagnetic field (50 Hz, 20 mT). The authors report increased osteogenic differentiation markers (gene expression, ALP activity, and calcium levels) under combined ZnSO4+EMF conditions,…

This review-style article discusses gerontechnologies—mobile applications on smartphones/tablets and remote monitoring systems—for outpatient symptom monitoring and self-care management in older adults with heart failure. It frames these tools as potentially cost-effective and accessible when designed for older…

This engineering study evaluates how anatomical/geometric differences affect MRI RF safety metrics. Simulations and a bovine-phantom experiment found that similar transmit B-field patterns can coincide with notably different peak SAR and temperature rise. The authors highlight challenges in using…

This retrospective study evaluated patient satisfaction and pain relief after pulsed radiofrequency treatment of the sphenopalatine ganglion for chronic facial and head pain. The abstract reports complete pain relief in 35% of patients, mild to moderate relief in 42%, and no acceptable relief in 23%. The authors…

This paper presents a near-field RF exposure assessment method comparing standard SAR estimation from E-field measurements in tissue-simulating liquid with a proposed approach based on incident H-field measurements. Experiments were conducted at 900, 1800, and 2450 MHz using dipole antennas and a flat phantom, with…

This observational space-physics study reports a substorm-associated injection of MeV electrons into the inner magnetosphere measured by Van Allen Probes-A. A strong dipolarization electric field (~50 mV/m) coincided with a dispersionless injection up to ~3 MeV and pitch angle signatures consistent with betatron…

This qualitative report describes phase one of a treatment development study for adolescent suicide prevention, including development of a safety plan smartphone application. Clinicians, parents, and adolescents emphasized transition of care, specific treatment targets, and safety planning as important. All…

This double-blind randomized placebo-controlled trial evaluated pulsed electromagnetic field (PEMF) therapy followed by a standardized shoulder strengthening exercise program in adults with shoulder impingement syndrome (N=56). The active PEMF group improved in pain and function from baseline across follow-ups, while…

This open case study assessed transcranially applied pulsed electromagnetic fields (PEMF) as a potential therapy for multiple chemical sensitivity (MCS) in three patients. Two of three patients reported considerable improvements in MCS-related symptoms/functional impairments and reduced capsaicin-induced secondary…

This engineering paper describes a fiber-based method for stable radio-frequency dissemination using a hybrid frequency modulation approach. Two RF components are transmitted simultaneously using a single laser diode, with one component used for phase fluctuation detection and the other providing a compensated stable…

This engineering/medical physics study used Monte Carlo simulations to examine how a uniform transverse magnetic field affects the dose distribution of a 30 MeV electron beam in a water phantom. The abstract reports substantial changes in depth-dose, including reduced range and a pronounced end-of-range dose peak…

This animal study compared rat liver and blood serum enzyme activities after a total two-hour exposure to low-intensity 900 MHz electromagnetic fields delivered as either a single or fractional schedule. The authors report that creatine kinase (liver and serum) and serum alkaline phosphatase were the most sensitive…

This paper presents a two-compartment computational model of CA3 pyramidal neurons to investigate how extracellular electric fields influence neuronal behavior via ephaptic transmission. The model is matched to subthreshold experimental responses at rest and used to analyze how DC and sinusoidal fields affect…

This study tested noninvasive 13.56 MHz radiofrequency electric fields as a treatment adjunct for pancreatic ductal adenocarcinoma in cell lines and mouse xenograft models. The authors report RF exposure caused cytotoxicity in PDAC cells via autophagy (not apoptosis) and that normal pancreatic ductal epithelial cells…
