The Influence of an Electromagnetic Field at a Radiofrequency of 900 MHz on the Behavior of a Honey Bee

Agriculture
The development of wireless technology and the desire to improve communication electromagnetic fields (EMFs) of various frequencies have become common across the honey bee’s foraging landscape.

Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

Pacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to

Carbohydrate intake of 10 g/kg body mass rapidly replenishes liver, but not muscle glycogen contents, during 12 h of post‐exercise recovery in well‐trained cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Exhaustive cycling exercise substantially reduces liver and muscle glycogen stores. During 12 h of post‐exercise recovery without carbohydrate intake, glycogen stores remain depleted. In contrast, when carbohydrate is consumed at 10 g/kg body mass (BM), provided during the first 6 h as sucrose beverages (1.2 g/kg BM/h), liver ...

Measurement and assessment of electromagnetic fields near radiophones in line with provisions of European Directive 2013/35/EU and Polish labour law

Medycyna Pracy, 2013
Background: The activities of rescue and uniformed services require the use of wireless communication devices, such as portable radiophones. Assessment of workers' exposure to electromagnetic fields emitted by radiophones is important in view of ...

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Radiofrequency and extremely low-frequency electromagnetic field effects on the blood-brain barrier

, 2008
During the last century, mankind has introduced electricity and during the very last decades, the microwaves of the modern communication society have spread a totally new entity--the radiofrequency fields--around the world.

Evaluation of 7 Tesla pTx Body Coils Regarding Transmit and Receive Performance

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2988-3001, December 2026.
ABSTRACT Purpose Most sites develop and use custom coils for 7 T body MRI since no standard pTx body coil exists, leading to diverse coil designs differing in transmit element type, layout, and number of receive channels. This study investigates and compares eight existing coils, including one remote body coil array and seven local arrays, regarding ...

Per‐Channel Complex B1+$$ {B}_1^{+} $$ Mapping for Parallel Transmit Ultra‐High Field MRI

NMR in Biomedicine, Volume 39, Issue 12, December 2026.
Transmit‐field inhomogeneities beset ultra‐high field (UHF) MRI scans using single‐channel transmission or circularly polarised (CP) mode. Parallel transmission mitigates these artefacts but requires accurate subject‐specific per‐channel complex (magnitude and phase) B1+$$ {B}_1^{+} $$ maps. We explain the theory of per‐channel complex B1+$$ {B}_1^{+} $
