Effect of millimeter waves on survival of UVC‐exposed Escherichia coli
Authors: Rojavin Mikhail A. , Ziskin Marvin C. 
Published: February 2006

AbstractBacterial cells of the strain Escherichia coli K12 were exposed to millimeter electromagnetic waves (mm waves) with and without additional exposure to ultraviolet light λ = 254 nm (UVC). The mm waves were produced by a medical microwave generator emitting a 4‐GHz‐wide band around a 61 GHz center frequency and delivering an irradiation of 1 mW/cm2 and a standard absorption rate (SAR) of 84 W/kg to the bacteria. Exposure to the mm waves alone for up to 30 minutes did not change the survival rate of bacteria. Exposure to mm waves followed by UVC irradiation also did not alter the number of surviving E. coli cells in comparison to UVC‐treated controls. When mm waves were applied after the UVC exposure, a dose‐dependent increase of up to 30% in the survival of E. coli was observed compared to UVC + sham‐irradiated bacteria. Because sham controls and experimental samples were maintained under the same thermal conditions, the effect is not likely to be due to heating, although the possibility of nonuniform distribution of microwave heating in different layers of irradiated bacterial suspension cannot be ruled out. The mechanism for this effect appears to involve certain DNA repair systems that act as cellular targets for mm waves. © 1995 Wiley‐Liss, Inc.
Acute low‐intensity microwave exposure increases DNA single‐strand breaks in rat brain cells
Authors: Lai Henry , Singh Narendra P. 
Published: February 2006

AbstractLevels of DNA single‐strand break were assayed in brain cells from rats acutely exposed to low‐intensity 2450 MHz microwaves using an alkaline microgel electrophoresis method. Immediately after 2 h of exposure to pulsed (2 μs width, 500 pulses/s) microwaves, no significant effect was observed, whereas a dose rate‐dependent [0.6 and 1.2 W/kg whole body specific absorption rate (SAR)] increase in DNA single‐strand breaks was found in brain cells of rats at 4 h postexposure. Furthermore, in rats exposed for 2 h to continuous‐wave 2450 MHz microwaves (SAR 1.2 W/kg), increases in brain cell DNA single‐strand breaks were observed immediately as well as at 4 h postexposure. © 1995 Wiley‐Liss, Inc.
Power lines and the geomagnetic field
Authors: Liboff Abraham R. , McLeod Bruce R. 
Published: February 2006

AbstractThe metric of prime interest in power line epidemiological studies has been AC magnetic intensity. To consider also possible geomagnetic involvement, the orientation of a long straight power line is examined relative to a uniform geomagnetic field (GMF) with dip angle α. An expression is derived for the component of the total GMF that is parallel, at an elevation β, to the circuital magnetic field that surrounds the line. This component is a function of the angles α and β, the total geomagnetic intensity BT, and the angle θ between the axis of the power line and magnetic north. Plotting these geomagnetic parameters for known leukemia residences allows one to test for possible ion cyclotron resonance or other GMF interactions. This approach, in principle, is an easy addition to existing or planned studies, because residential access is not required to obtain local values for α, β, θ, and BT. We recommend including these parameters in the design of epidemiological studies examining power line fields and childhood leukemia. © 1995 Wiley‐Liss, Inc.
Applied AC and DC magnetic fields cause alterations in the mitotic cycle of early sea urchin embryos
Authors: Levin Michael , Ernst Susan G. 
Published: February 2006

AbstractThis study demonstrates that exposure to 60 Hz magnetic fields (3.4–8.8 mT) and magnetic fields over the range DC‐600 kHz (2.5–6.5 mT) can alter the early embryonic development of sea urchin embryos by inducing alterations in the timing of the cell cycle. Batches of fertilized eggs were exposed to the fields produced by a coil system. Samples of the continuous cultures were taken and scored for cell division. The times of both the first and second cell divisions were advanced by ELF AC fields and by static fields. The magnitude of the 60 Hz effect appears proportional to the field strength over the range tested. The relationship to field frequency was nonlinear and complex. For certain frequencies above the ELF range, the exposure resulted in a delay of the onset of mitosis. The advance of mitosis was also dependent on the duration of exposure and on the timing of exposure relative to fertilization. © 1995 Wiley‐Liss, Inc.
Frequency‐dependent interference by magnetic fields of nerve growth factor‐induced neurite outgrowth in PC‐12 cells
Authors: Blackman C. F. , Benane S. G. , House D. E. 
Published: February 2006

AbstractWe have shown that 50 Hz sinusoidal magnetic fields within the 5‐10 micro Tesla (μT) rms range cause an intensity‐dependent reduction in nerve growth factor (NGF) stimulation of neurite outgrowth (NO) in PC‐12 cells. Here we report on the frequency dependence of this response over the 15‐70 Hz range at 5 Hz intervals. Primed PC‐12 cells were plated in collagen‐coated, 60 mm plastic petri dishes with or without 5 ng/ml NGF and were exposed to sinusoidal magnetic fields for 22 h in a CO2incubator at 37 °C. One 1,000‐turn coil, 20 cm in diameter, generated vertically oriented magnetic fields. The dishes were stacked on the center axis of the coil to provide a range of intensities between 3.5 and 9.0 μT rms. The flux density of the ambient DC magnetic field was 37 μT vertical and 19 μT horizontal. The assay consisted of counting over 100 cells in the central portion (radius ≤0.3 cm) of each dish and scoring cells positive for NO. Sham exposure of cells treated identically with NGF demonstrated no difference in the percentage of cells with NO between exposed and magnetically shielded locations within the incubator. Analysis of variance demonstrated flux density‐dependent reductions in NGF‐stimulated NO over the 35‐70 Hz frequency range, whereas frequencies between 15 Hz and 30 Hz produced no obvious reduction. The results also demonstrated a relative maximal sensitivity of cells at 40 Hz with a possible additional sensitivity region at or above 70 Hz. These findings suggest a biological influence of perpendicular AC/DC magnetic fields different from those identified by the ion parametric resonance model, which uses strictly parallel AC/DC fields. © 1995 Wiley‐Liss, Inc.
Comment on „designing EMF experiments: What is required to characterize ‘exposure’?”︁
Authors: Kaune W. T. 
Published: February 2006

AbstractDr. Peter Valberg has written an excellent and clear paper describing our current understanding of the many facets of characterizing exposure to extremely‐low‐frequency (ELF) electric and magnetic fields. Dr. Valberg has directed his paper to the characterization of exposures used in laboratory experimentation. In this context, it seems to me that Valberg's program of exposure characterization can be accomplished with currently available instrumentation and with relatively modest effort. Thus, I have no fundamental problems with his recommendations and, really, have only a few minor comments to make. However, if one argues that Valberg's recommendations should be extended to the characterization of exposure in epidemio‐logical research, I have serious reservations, which I will mention briefly at the end of this commentary. © 1995 Wiley‐Liss, Inc.
Normal mode analysis of the horseradish peroxidase collective motions: Correlation with spectroscopically observed heme distortions
Authors: Laberge Monique , Kovesi Istvan , Yonetani Takashi , Fidy Judit 
Published: February 2006

AbstractHorseradish peroxidase C is a class III peroxidase whose structure is stabilized by the presence of two endogenous calcium atoms. Calcium removal has been shown to decrease the enzymatic activity of the enzyme and significantly affect the spectroscopically detectable properties of the heme, such as the spin state of the iron, heme normal modes, and distortions from planarity. In this work, we report on normal mode analysis (NMA) performed on models subjected to 2 ns of molecular dynamics simulations to describe the effect of calcium removal on protein collective motions and to investigate the correlation between active site (heme) and protein matrix fluctuations. We show that in the native peroxidase model, heme fluctuations are correlated to matrix fluctuations while they are not in the calcium‐depleted model. © 2006 Wiley Periodicals, Inc.

Impact of oedema on recovery after major abdominal surgery and potential value of multifrequency bioimpedance measurements
Authors: Itobi E , Stroud M , Elia M 
Published: February 2006

Abstract

Background
The consequences of generalized oedema following major abdominal surgery are under-recognized, and its causes are poorly understood.

Methods
Thirty-eight patients (21 men and 17 women) were observed for the occurrence of oedema after major abdominal surgery. Oedema formation was related to fluid balance, changes in whole-body bioimpedance (Z) measured at four frequencies (5, 50, 100 and 200 kHz), and clinical outcome.

Results
The 20 patients who developed oedema were older than those who did not (mean(s.d.) 73(9) versus 63(14) years; P = 0·007). Fluid intake over the first 5 days after surgery was similar in both groups, but those with oedema excreted less total fluid (16·9(2·4) versus 19·7(3·5) litres; P = 0·022). Oedema was associated with a delay in tolerating solid food (P = 0·001) and opening bowels (P = 0·020), a prolonged hospital stay (median 17 (range 8–59) versus 9 (range 4–27) days; P = 0·001) and more postoperative complications (13 of 20 versus four of 18 patients; P = 0·011). The preoperative ratio of whole-body impedance at 200 kHz to that at 5 kHz was higher in those who subsequently developed oedema (0·81(0·03) versus 0·78(0·02); P = 0·015).

Conclusion
The development of oedema after major abdominal surgery is associated with increased morbidity. Age and reduced ability to excrete administered fluid load are significant aetiological factors and bioimpedance analysis can potentially identify patients at risk.

Defining “Success” in recruitment of underrepresented populations to cancer clinical trials
Authors: Bolen Shari , Tilburt Jon , Baffi Charlie , Gary Tiffany L. , Powe Neil , Howerton Mollie , Ford Jean , Lai Gabriel , Wilson Renee , Bass Eric 
Published: February 2006

AbstractAlthough medically underserved groups bear a heavy burden of cancer disease and governmental agencies have required inclusion of minorities and women in cancer clinical trials since 1993, many of these groups are underrepresented in cancer prevention or treatment clinical trials. To assess and enhance recruitment of underrepresented populations into cancer‐related clinical trials, investigators and governmental agencies need consistent measurement approaches for recruitment that can be applied to diverse settings where trials are conducted. We conducted a systematic review to evaluate what measurement approaches were used to evaluate the success of recruitment of underrepresented groups into cancer prevention or treatment trials, and whether these recruitment goals were stated a priori. Only two articles reported an a priori recruitment goal. The recruitment measurement approaches varied considerably, with no consistent standard, especially for individual trials. By using the empiric evidence from this review in conjunction with the National Institutes of Health (NIH) guidelines, we constructed a framework for choosing consistent a priori recruitment goals for underrepresented groups based on the research question and study location. Using consistent measurement approaches for underrepresented groups will improve comparability of recruitment strategies across trials, improve equity in distribution of benefits and burdens of cancer‐related clinical trials, and may improve applicability of trial results to multiple populations.

Clarification of differences between variable achromatic color and variable chromatic color methods in the Helmholtz–Kohlrausch effect
Authors: Nayatani Yoshinobu , Sakai Hideki 
Published: February 2006

AbstractThe Helmholtz–Kohlrausch effect consists of two different approaches: the variable achromatic color (VAC) and variable chromatic color (VCC) methods. In this article the difficult conceptual difference between the methods is clarified using new explanations with their schematic figures. The concept of loci with various parameters on B/L or L/Y ratios is completely different between the two methods. The VCC method can determine perceived lightness values for achromatic and chromatic colors in the whole color space. The VAC method gives perceived lightness deviation between reference achromatic color and each of the various test chromatic colors both kept at the same Munsell Value. The VAC method can never give any information on equiperceived lightness to test chromatic colors. Despite the difference between the two methods, misuse of the VAC method is sometimes found for perceived lightness studies of various chromatic colors, because of its ease in observations. An example is shown for the L scale of OSA‐UCS. © 2006 Wiley Periodicals, Inc. Col Res Appl, 31, 146–155, 2006

Mediated electron transfer from glucose oxidase at a ferrocene‐modified graphite electrode
Authors: Jönsson G. , Gorton L. , Pettersson L. 
Published: February 2006

AbstractA new ferrocene derivative was synthesized by reacting hydroxymethylferrocene with anthracene‐9‐carboxylic acid. This new compound strongly adsorbs on the surface of a graphite electrode to form a stable chemically modified electrode. The formal potential of the adsorbed ferrocene derivative was +340 mV versus SCE in solutions containing 0.1 M perchlorate. When adsorbed, the ferrocene derivative mediates the charge transfer between the electrode and glucose oxidase.
