Development of a cell phone-based video streaming system for persons with early stage Alzheimer's disease.

Research RF Safe Research Library Jan 1, 2008

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…

A benzene-core trinuclear GdIII complex: towards the optimization of relaxivity for MRI contrast agent applications at high magnetic field.

Research RF Safe Research Library Jan 1, 2008

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…

Ultrastructural alterations and occurrence of apoptosis in developing follicles exposed to low frequency electromagnetic field in rat ovary.

Research RF Safe Research Library Jan 1, 2007

This animal study examined rat ovaries after chronic exposure to a 3 mT low-frequency electromagnetic field for 4 hours per day over 4 months. Using TEM and TUNEL, the authors report ultrastructural alterations in oocytes and more frequent apoptosis-associated changes in granulosa and corona radiata cells versus…

Proteomic analysis in human fibroblasts by continuous exposure to extremely low-frequency electromagnetic fields.

Research RF Safe Research Library Jan 1, 2007

This in vitro study examined whether continuous extremely low-frequency electromagnetic fields (3 Hz, 4 mT for 3 hours) alter protein expression in human fibroblast cells using proteomics. The authors report that some protein expressions differed between exposed and sham cells. They identify reduced expression (about…

Effects of electromagnetic field produced by mobile phones on the oxidant and antioxidant status of rats.

Research RF Safe Research Library Jan 1, 2007

This rat study examined whether EMR from GSM mobile phones affects oxidant/antioxidant status. Compared with controls, exposed rats had lower plasma antioxidant vitamins (C, E, A), reduced glutathione, and lower CAT and SOD activities. The acute exposure condition was reported to produce larger decreases than the…

900 MHz radiofrequency-induced histopathologic changes and oxidative stress in rat endometrium: protection by vitamins E and C.

Research RF Safe Research Library Jan 1, 2007

This rat study examined 900 MHz radiofrequency exposure (30 min/day for 30 days) and reported biochemical and histopathologic changes in endometrial tissue consistent with oxidative stress and tissue injury. The abstract reports increased NO and MDA and decreased antioxidant enzyme activities (SOD, CAT, GSH-Px) in…

Aerodynamically assisted bio-jets: the development of a novel and direct non-electric field-driven methodology for engineering living organisms.

Research RF Safe Research Library Jan 1, 2007

This paper describes an aerodynamically assisted bio-jetting technique that processes living cells/organisms using differential pressure rather than an electric field. The authors report an operational window for stable jetting and near-monodispersed cell-bearing droplets. Cell viability after jetting was evaluated…

The influence of combined magnetic field on the fusion of plant protoplasts.

Research RF Safe Research Library Jan 1, 2007

This laboratory study examined whether a weak alternating magnetic field tuned to the cyclotron frequency of Ca2+ and K+ ions influences fusion of tobacco and soya protoplasts. The abstract reports a 2–3× increase in protoplast fusion frequency under exposure. It also reports involvement of calcium ions in induction…

AC electric field-induced alignment and long-range assembly of multi-wall carbon nanotubes inside aqueous media.

Research RF Safe Research Library Jan 1, 2007

This engineering study examines multi-wall carbon nanotubes suspended in water exposed to AC electric fields generated by 3D electrodes. It reports field-induced polarization leading to nanotube alignment and long-range, electrically conducting assemblies spanning the electrode gap, with assembly length controlled by…

Electric field-induced astrocyte alignment directs neurite outgrowth.

Research RF Safe Research Library Jan 1, 2006

This in vitro study examined whether astrocyte alignment induced by an applied electric field influences neurite outgrowth. Astrocytes were pre-aligned using a physiological-strength electric field (500 mV mm(-1)), and dorsal root ganglia cells were then seeded onto them. Neurite outgrowth at 24 and 48 hours was…

Headaches from cellular telephones: are they real and what are the implications?

Research RF Safe Research Library Mar 1, 1998

This review discusses reports of headaches occurring with hand-held cellular telephone use and argues they are likely real and attributable to telephone emissions. It points to earlier reports of headaches from low-intensity microwave exposure and proposes biological plausibility via effects on the blood-brain…

The effect of pulsed and sinusoidal magnetic fields on the morphology of developing chick embryos

Research RF Safe Research Library Jan 1, 1997

This animal study reports results from five experimental campaigns over five years examining weak magnetic field exposure and morphological abnormalities in White Leghorn chick embryos. Four campaigns reported statistically significant increases in abnormality rates, while one pulsed-field campaign showed only a…
