section on the Interphone study
site now has a completely new section on the Interphone study. It
can be found under "Research
Programs". It contains Tables summarizing the results of
the papers that have been published from the centres participating
in the study. It is expected that the main results of the Interphone
study, including the summary of the results from all 13 participating
countries, will be published in the next 6 to 12 months.
review of the validity of epidemiological studies on health effects
of cell phones
and colleagues have published a paper that reviews the factors that
can affect the validity of epidemiological studies on health effects
of cell phones. They emphasize the imprecision of exposure assessment
in the studies. The authors also point out that this is particularly
likely to occur in case-control studies, and that prospective studies
afford the best opportunity to improve the quality of evidence.

exposure and gene expression - danger of false positives
and colleagues have published previously on the subject of gene
expression. In the current experiment they exposed C3H 10T 1/2 cells
to RFR for 24 hours at a SAR of 5 W/kg. FDMA or CDMA RF was used.
The number of gene expression changes induced by RFR was not greater
than the number of false positives expected based on a sham versus
sham comparison. In contrast, the X-irradiated samples showed higher
number of changed expression level than in the sham versus sham
et al. also investigated gene responses to RFR exposure, and concluded
that the exposure did not produce distinct effects on gene and protein

EMF research in Europe
Lin, in his latest paper in Radio Science Bulletin, discusses bioelectromagnetic
research in Europe. He points out that the European Union is probably
the leader in this area, with the total amount of funding of US$53.74
million for current projects.

plastic sealer operators and heart rate variability
and colleagues reported in an earlier study that RF plastic sealer
operators had lower heart rates and more episodes of disturbed heart
rhythm than controls. They now report that this might be due to
a compensatory increase in the parasympathetic nervous system.
