[Conclusion: probable and possible futures. MRI with ultra high magnetic field].

RF Safe Research Library Jan 1, 2009 REASSURANCE LOW

This narrative piece states that MR neuroimaging does not interfere with brain function and is safe for use in patients and healthy volunteers. It argues that ultra-high-field MRI could substantially improve spatiotemporal resolution, potentially enabling study of brain function at finer scales.…

The possibilities of radiofrequency technology in the surgery of parenchimatous organs.

RF Safe Research Library Jan 1, 2009 NEUTRAL LOW

This clinical report describes the use of radiofrequency (RF) technology in surgery of abdominal and thoracic parenchymatous organs in 17 patients. The authors report one complication (pleural effusion) and otherwise no additional organ complications in the abstract. They also describe a case of…

Static magnetic field therapy: a critical review of treatment parameters.

RF Safe Research Library Jan 1, 2009 NEUTRAL MEDIUM

This critical review summarizes human research on static magnetic field (SMF) therapy delivered by permanent magnets attached to the skin and evaluates how well studies report SMF dosage and treatment parameters. Across 56 included studies, many did not report essential SMF characteristics (e.g.,…

Biological effects from electromagnetic field exposure and public exposure standards

RF Safe Research Library Jan 1, 2008 CONCERN LOW

This review describes public concerns and scientific reports of non-thermal biological effects from low-intensity ELF and RF exposures. It lists multiple health endpoints reported to be associated with ELF and/or RF and highlights the BioInitiative Report’s conclusion that a reasonable suspicion…

Genetic damage in mammalian somatic cells exposed to radiofrequency radiation: a meta-analysis of data from 63 publications (1990-2005)

RF Safe Research Library Jan 1, 2008 NEUTRAL HIGH

A meta-analysis of 63 publications assessed whether radiofrequency (RF) radiation exposure is associated with genetic damage in mammalian somatic cells using multiple genotoxicity endpoints. Overall differences between RF-exposed and control conditions were reported as small, though statistically…

Effects of mobile phone use on specific intensive care unit devices.

RF Safe Research Library Jan 1, 2008 CONCERN MEDIUM

This study tested electromagnetic interference from GSM and CDMA mobile phones placed one foot from ICU devices (syringe pump, mechanical ventilator, bedside monitor) in off, standby, and talk modes. EMI was observed for the syringe pump in talk mode, with a mean 2.66 ml variation between…

Synthesis of polylactic acid-polyglycolic acid blends using microwave radiation.

RF Safe Research Library Jan 1, 2008 NEUTRAL MEDIUM

This engineering/materials study describes blending PLLA and PGA using microwave irradiation to produce PLGA-related blends with varying constituent concentrations. The authors report that FTIR, NMR, and DSC measurements indicate blending and cross-linking between the polymers. The abstract does…

Head-to-head comparison of coronary plaque evaluation between multislice computed tomography and intravascular ultrasound radiofrequency data analysis.

RF Safe Research Library Jan 1, 2008 NEUTRAL MEDIUM

This study compared coronary plaque assessment by 64-slice multislice computed tomography (MSCT) with virtual histology intravascular ultrasound (VH IVUS) in 50 patients. The Agatston score on MSCT correlated moderately with calcium volume measured by VH IVUS, and MSCT plaque categories broadly…

Apparent violation of the Wiedemann-Franz law near a magnetic field tuned metal-antiferromagnetic quantum critical point.

RF Safe Research Library Jan 1, 2008 NEUTRAL MEDIUM

This paper reports calculations of interlayer electrical and thermal resistivity in a layered metal assuming Fermi-liquid quasiparticles inelastically scattered by two-dimensional antiferromagnetic spin fluctuations. The model yields linear-in-temperature behavior over a broad range and suggests…

Silicon-on-insulator-based radio frequency single-electron transistors operating at temperatures above 4.2 K.

RF Safe Research Library Jan 1, 2008 NEUTRAL MEDIUM

This engineering study demonstrates a silicon-on-insulator (SOI) radio-frequency single-electron transistor (RF-SET) operating at temperatures above 4.2 K. The device was optimized to address high resistance in SOI SETs and showed stable transport characteristics after repeated thermal cycling.…

Velocity modulation of microtubules in electric fields.

RF Safe Research Library Jan 1, 2008 NEUTRAL MEDIUM

This in vitro study reports that electric fields can control the velocity of microtubules gliding over a kinesin-coated surface. Assisting fields increased speed up to fivefold, while opposing fields slowed motion to zero, and sideways fields induced significant motion. The authors present a…

[Effect of 1.8 GHz radiofrequency electromagnetic fields on gene expression of rat neurons].
