• Meta-analysis of long-term mobile phone use and the association with brain tumours
  24 de abril de 2008 · 4063 lecturas
  
  

  Abstract. We evaluated long-term use of mobile phones and the risk for brain tumours in case-control studies published so far on this issue. We identified ten studies on glioma and meta-analysis yielded OR = 0.9, 95% CI = 0.8-1.1. Latency period of ¡�10-years gave OR = 1.2, 95% CI = 0.8-1.9 based on six studies, for ipsilateral use (same side as tumour) OR = 2.0, 95% CI = 1.2-3.4 (four studies), but contralateral use did not increase the risk significantly, OR = 1.1, 95% CI = 0.6-2.0.

• Exposure to cell phone radiation up-regulates apoptosis
  18 de abril de 2008 · 4334 lecturas
  
  

  Abstract The health effects of cell phone radiation exposure are a growing public concern. This study investigated whether expression of genes related to cell death pathways are dysregulated in primary cultured neurons and astrocytes by exposure to a working Global System for Mobile Communication (GSM) cell phone rated at a frequency of 1900 MHz. Primary cultures were exposed to cell phone emissions for 2 h. We used array analysis and real-time RT-PCR to show up-regulation of caspase-2, (...)
