Jan 1, 2014
This study examined how pulsed electric field, hot water dip, ethanol vapours, and UV irradiation affected antioxidant-related properties of mung bean sprouts during storage at room and low temperatures. Ethanol vapour-treated sprouts had the highest ascorbic acid, total phenols, and antioxidant activity. Polyphenol…
Optimization of a therapeutic electromagnetic field (EMF) to retard breast cancer tumor growth and vascularity.

Jan 1, 2014
This animal study evaluated a therapeutic 120 Hz pulsed EMF device (10–20 mT) in C3H mice bearing implanted murine mammary adenocarcinoma tumors. Across seven treated groups, EMF exposure over 12 days was reported to suppress tumor growth, with specific dose/time regimens described as most effective. The authors also…
Effect of pulsed radiofrequency neuromodulation on clinical improvements in the patients of chronic intractable shoulder pain.
Research
RF Safe Research Library
Jan 1, 2013
This study evaluated pulsed radiofrequency (PRF) neuromodulation of the suprascapular nerve in 11 patients with chronic shoulder pain from adhesive capsulitis and/or rotator cuff tear. Pain (VAS) and shoulder-related quality of life/function (OSS) were assessed before treatment and monthly after PRF for up to 9…
Motion properties of the sanals of the primo vascular system under a magnetic field.
Research
RF Safe Research Library
Jan 1, 2013
This animal/lab study examined motion of ~1 μm sanals from the rabbit primo vascular system under a low static magnetic field (100 Oe). The reported average velocity of five sanals in saline was ~1.0 pixel/second in random directions relative to the field. The authors suggest the applied magnetic field weakens sanal…
Induction of thrombosis of the abdominal aneurysm sac through the application of radiofrequency. An experimental study.
Research
RF Safe Research Library
Jan 1, 2012
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…
Effects of radiofrequency radiation exposure on blood-brain barrier permeability in male and female rats
Research
RF Safe Research Library
Jan 1, 2011
This rat study tested whether acute exposure to 0.9 and 1.8 GHz continuous-wave radiofrequency radiation alters blood-brain barrier permeability. Using Evans-blue/albumin as a tracer, the authors report no BBB leakage in exposed female rats but a significant increase in albumin in exposed male rat brains versus sham.…
Radiofrequency microtenotomy for the treatment of plantar fasciitis shows good early results.

This small clinical case series evaluated TOPAZ radiofrequency coblation microtenotomy for recalcitrant plantar fasciitis in 14 patients. The abstract reports improved AOFAS hindfoot scores at 3 and 6 months and improvements in several SF-36 domains, with most patients reporting good-to-excellent satisfaction. The…
In vitro magnetic stimulation of pig phrenic nerve with transverse and longitudinal induced electric fields: analysis of the stimulation site.
