MORE STUDIES BELOW
Studies are hard to interpret due to the fact that so many are paid for or sponsored in some way by the giant corporations that sell phone and satellite services. Even our own Federal agencies are from what we have seen susceptible to the political factions that make their fortunes off the industry. Every time a new study is released that is damaging to the industry, two or three studies are rushed forth by other research groups to counter any damage. We have noticed in our research that radiofrequency radiation was found by many American researchers to be dangerous in the United States, prior to 1985. When the new communications industry started up in the mid 1980s and federal grants for research dried up, it was no longer dangerous. Also when you consider the fact that there are ten of thousands of studies that show this kind of radiation does cause damage to biological tissue that should be some kind of warning to all of us. We will present a few older studies and a few recent studies and let you make up your own mind. Some of it can be confusing as we are all not medical experts. We basically will be using abstracts from the studies which are for the most part easy enough to understand. We think the bottom line is to ask your self, is radiation known to be a toxic substance? The answer to that question should put most of us adults on alert. We will try to update this page with different studies and facts each month so do bookmark our site and return often.
1. Study A: Cell phone radiation could potentially up-regulate mRNA of some proteins in rat brain.
In this experiment, rats were used and exposed to cell phones for 6 hours each day during a period of 18 weeks. The authors investigated whether changes in the levels of mRNA synthesis of a number of proteins would be affected by cell phone radiation. The results of the study indicate that mRNA of the proteins was up-regulated and this was judged to be statistically significant. The conclusion of the paper is that exposure to cell phone radiation could ultimately result in cumulative injuries and produce clinical neurological damage.

2. Apparent changes although not statistically significant in heart rate variability due to mobile phone use. This study was designed to assess the neurological effect through heart rate variability from mobile phone use. Two heart rate parameters, scaling exponent and sample entropy, were both measured and showed an increase while the mobile phone was used close to the chest and a decrease when used close to the head. Although some changes occurred, the results could not be considered to be statistically significant.

3. Spindle disturbances due to 835 MHz radiofrequency field in human-hamster hybrid.
The current research was designed to assess the health effect of non-ionizing radiation on the production of spindle disturbances in a human-hamster cell line. Results of the experiments from exposure to non-ionization radiation with field strength of 90 V/m and a frequency of 835 MHz during 0.5 to 2 hours indicate spindle disturbances at two stages of cellular divisions.

BACKGROUND: For the past two decades, there has been concern over electromagnetic exposure and human health. While most research has focused on cancer and reproductive outcomes, there is interest in the
relationship between electromagnetic fields (EMF) and neurodegenerative diseases.
METHODS: We review epidemiological findings and evidence regarding the association between occupational exposure to power frequency EMFs and amyotrophic lateral sclerosis (ALS). Medline was searched for citations
related to occupational hazards and ALS, literature reviews and epidemiological evaluations.
RESULTS: Nine out of the ten epidemiological studies that have been conducted on the risk of ALS in relation to occupational exposure to EMF show moderate to strong relative risk estimates that supported a link between them.
Although data from these studies was consistent, the causal inference to a link between EMF exposure and ALS is restricted mainly due to the lack of direct information on EMF exposure and incomplete consideration of the other potential risk factors for ALS at workplaces. For instance, electric shock, in particular, is more common in electrical occupations than in any other occupations.
CONCLUSIONS: This review concludes that further studies should consider investigating the separate effect of EMF exposure and electrical shocks to make more specific interpretations. On-site measurements of EMF should be conducted to include information on EMF exposure from residences as well as workplaces to improve exposure assessment. — Source: Am J Ind Med 2003 Feb;43(2):212-20.

900 MHz radiofrequency-induced histopathologic changes and oxidative stress in rat endometrium: protection by vitamins E and C. — Department of Obstetrics and Gynecology, Faculty of Medicine, Suleyman Demirel University, Isparta, Turkey. firstname.lastname@example.org — There are numerous reports on the effects of electromagnetic radiation (EMR) in various cellular systems. Mechanisms of adverse effects of EMR indicate that reactive oxygen species (ROS) may play a role in the biological effects of this radiation. The aims of this study were to examine 900 MHz mobile phone-induced oxidative stress that promotes production of ROS and to investigate the role of vitamins E and C, which have antioxidant properties, on endometrial tissue against possible 900 MHz mobile phone-induced endometrial impairment in rats. The animals were randomly grouped (eight each) as follows: 1) Control group (without stress and EMR, Group I), 2) sham-operated rats stayed without exposure to EMR (exposure device off, Group II), 3) rats exposed to 900 MHz EMR (EMR group, Group III) and 4) a 900 MHz EMR exposed + vitamin-treated group (EMR + Vit group, Group IV). A 900 MHz EMR was applied to EMR and EMR + Vit group 30 min/day, for 30 days using an experimental exposure device. Endometrial levels of nitric oxide (NO, an oxidant product) and malondialdehyde (MDA, an index of lipid peroxidation), increased in EMR exposed rats while the combined vitamins E and C caused a significant reduction in the levels of NO and MDA. Likewise, endometrial superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities decreased in EMR exposed animals while vitamins E and C caused a significant increase in the activities of these antioxidant enzymes. In the EMR group histopathologic changes in endometrium, diffuse and severe apoptosis was present in the endometrial surface epithelial and glandular cells and the stromal cells. Diffuse eosinophilic leucocyte and lymphocyte infiltration were observed in the endometrial stroma whereas the combination of vitamins E and C caused a significant decrease in these effects of EMR. It is concluded that oxidative endometrial damage plays an important role in the 900 MHz mobile phone-induced endometrial impairment and the modulation of oxidative stress with vitamins E and C reduces the 900 MHz mobile phone-induced endometrial damage both at biochemical and histological levels.
