Evaluation of 4.0 GHz RF Exposure Effects on Bioaerosols Containing Bovine Coronavirus.

This in vitro study tested whether 4.0 GHz microwave exposure affects survival of aerosolized bovine coronavirus in a waveguide system. Using TCID assays, the authors report no statistically significant reduction in virus survival compared with controls and no significant change in variability. The paper emphasizes…

Effects of Anatomical Differences on Electromagnetic Fields, SAR, and Temperature Change.

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…

Electromagnetic fields counteract IL-1β activity during chondrogenesis of bovine mesenchymal stem cells.

This in vitro study examined whether electromagnetic fields (EMFs) influence chondrogenic differentiation of bovine mesenchymal stem cell pellets, with and without the inflammatory cytokine IL-1β. The authors report EMFs had limited effects on chondrogenesis in the absence of inflammation, but in the presence of…

Comparison between different thickness umbrella-shaped expandable radiofrequency electrodes (SuperSlim and CoAccess): Experimental and clinical study.

This experimental and clinical study compared two umbrella-shaped expandable radiofrequency ablation electrodes (SuperSlim vs CoAccess) across different ablation algorithms. In ex vivo bovine liver, CoAccess generally produced larger ablation areas and required longer ablation times than SuperSlim, with no…
