This article suggests that electromagnetic processes deriving from the chemistry of an organism may provide such coordination. Specifically, the author develops the pacemaker concept, the periodic, autonomous electrical signal to the entire embryo, the result of which, after each pulse, is to alter or enlarge the transcriptome to produce the next level of complexity and maturity of the organism.</p>","PeriodicalId":29923,"journal":{"name":"Bioelectricity","volume":"6 3","pages":"196-203"},"PeriodicalIF":1.6,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11447481/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142381783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This nonthermal therapy has been used to treat a wide range of murine tumors and has been shown to activate the immune system to inhibit the growth of rechallenge tumors, as well as untreated, abscopal tumors when accompanied by the injection of immune system stimulants into the treated tumors. Clinical trials have begun using NPS to treat basal cell carcinoma and hepatocellular carcinoma.</p><p><strong>Methods: </strong>Murine tumors can be easily imaged when the tumor cells are injected intradermally so that they grow within the mouse skin.

The energy required to ablate these tumors has been determined with pancreatic carcinoma and lung carcinoma exhibiting 90% ablation with 240 mJ/mm³, lung carcinoma and squamous cell carcinoma requiring 360 mJ/mm³, and melanoma requiring 480 mJ/mm³.

The main differences between NPS therapy and other ablation modalities are the level of fibrosis, amount of scarring, elastic fiber concentration, and inflammation.
