The present study confirms these observations and extends them from diptera and mammalian cells to yeast. It shows that the effects are gene specific, that the gene remains 'on' for a relatively short period of time, and that a refractory period is necessary before the gene can be restimulated. There is a correlation between response to such fields and to other cellular stress responses suggesting that the cell 'sees' the signal as a stress. Models to explain the interaction of EM fields with cells are discussed.<<ETX>>","PeriodicalId":381113,"journal":{"name":"[Proceedings] 1992 Regional Symposium on Electromagnetic Compatibility","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131170337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further procedures of magnetotelluric sounding interpretation must include calculations of the spatial field spectrum and spectral impedance.<<ETX>>","PeriodicalId":381113,"journal":{"name":"[Proceedings] 1992 Regional Symposium on Electromagnetic Compatibility","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114798759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
