  Historical evidence that electrification caused the 20th century epidemic of ��diseases of civilization”
  s u m m a r y The slow spread of residential electrification in the US in the first half of the 20th century from urban to rural areas resulted by 1940 in two large populations; urban populations, with nearly complete electrification and rural populations exposed to varying levels of electrification depending on the progress of electrification in their state. It took until 1956 for US farms t

  The influence of handheld mobile phones on human parotid gland secretion
  BACKGROUND: Handheld mobile phones (MPHs) have become a -cultural’ accessory device, no less so than a wrist watch. Nevertheless, the use of MPHs has given rise to great concern because of possible adverse health effects from exposure to the radiofrequency radiation (RFR) emitted by the device. Previous studies suggested correlation between MPH and salivary gland tumors. OBJECTIVE: To evaluate whether MPH induces (...)
