Epub 2015 Feb 2. PMID: 25649190 Abstract Title:  Exposure to non-ionizing radiation provokes changes in rat thyroid morphology and expression of HSP-90. Abstract:  Non-ionizing radiation at 2.45 GHz may modify the morphology and expression of genes that codify heat shock proteins (HSP) in the thyroid gland. Diathermy is the therapeutic application of non-ionizing radiation to humans for its beneficial effects in rheumatological and musculo-skeletal pain processes. We used a diathermy model on laboratory rats subjected to maximum exposure in the left front leg, in order to study the effects of radiation on the nearby thyroid tissue. Fifty-six rats were individually exposed once or repeatedly (10 times in two weeks) for 30 min to 2.45 GHz radiation in a commercial chamber at different non-thermal specific absorption rates (SARs), which were calculated using the finite difference time domain technique. We used immunohistochemistry methods to study the expression of HSP-90 and morphological changes in thyroid gland tissues. Ninety minutes after radiation with the highest SAR,the central and peripheral follicles presented increased size and the thickness of the peripheral septa had decreased. Twenty-four hours after radiation, only peripheral follicles radiated at 12 W were found to be smaller. Peripheral follicles increased in size with repeated exposure at 3 W power. Morphological changes in the thyroid tissue may indicate a glandular response to acute or repeated stress from radiation in the hypothalamic-pituitary-thyroid axis. Further research is needed to determine if the effect of this physical agent over time may cause disease in the human thyroid gland. <p><a href="https://greenmedinfo.com/article/245-ghz-exposure-leads-morphological-changes-rat-thyroid-which-may-indicate-gl" target="_blank">read more</a></p> https://greenmedinfo.com/article/245-ghz-exposure-leads-morphological-changes-rat-thyroid-which-may-indicate-gl#comments Cell Phone Exposure Electromagnetic Field Harms Electromagnetic Radiation Electromagnetic Radiation: 2.4 GHz Microwave Radiation Mobile Phone Radiation electromagnetic fields electromagnetic frequencies electromagnetic radiation EMF Radio Frequency Electromagnetic Radiation Exposure Thyroid Animal Study Fri, 02 Aug 2019 23:29:49 +0000 greenmedinfo 192705 at https://greenmedinfo.com Bisphenol A influences oestrogen and thyroid hormone-regulated thyroid hormone receptor expression. https://greenmedinfo.com/article/bisphenol-influences-oestrogen-and-thyroid-hormone-regulated-thyroid-hormone-r n/a PMID:  Acta Vet Hung. 2016 Dec ;64(4):497-513. PMID: 27993100 Abstract Title:  Bisphenol A influences oestrogen- and thyroid hormone-regulated thyroid hormone receptor expression in rat cerebellar cell culture. Abstract:  Thyroid hormones (THs) and oestrogens are crucial in the regulation of cerebellar development. TH receptors (TRs) mediate these hormone effects and are regulated by both hormone families. We reported earlier that THs and oestradiol (E2) determine TR levels in cerebellar cell culture. Here we demonstrate the effects of low concentrations (10(-10) M) of the endocrine disruptor (ED) bisphenol A (BPA) on the hormonal (THs, E2) regulation of TRα,β in rat cerebellar cell culture. Primary cerebellar cell cultures, glia-containing and glia-destroyed, were treated with BPA or a combination of BPA and E2 and/or THs. Oestrogen receptor and TH receptor mRNA and protein levels were determined by real-time qPCR and Western blot techniques. The results show that BPA alone decreases, while BPA in combination with THs and/or E2 increases TR mRNA expression. In contrast, BPA alone increased receptor protein expressions, but did not further increase them in combination with THs and/or E2. The modulatory effects of BPA were mediated by the glia;however, the degree of changes also depended on the specific hormone ligand used. The results signify the importance of the regulatory mechanisms interposed between transcription and translation and raise the possibility that BPA could act to influence nuclear hormone receptor levels independentlyof ligand-receptor interaction. https://greenmedinfo.com/article/bisphenol-influences-oestrogen-and-thyroid-hormone-regulated-thyroid-hormone-r#comments Bisphenol Toxicity Bisphenol A Bisphenol A Bisphenol Toxicity Risk Factors Thyroid Animal Study Thu, 22 Dec 2016 19:03:31 +0000 greenmedinfo 140853 at https://greenmedinfo.com Potassium Iodide: A Critical Component of Nuclear Emergency Preparedness https://greenmedinfo.com/blog/potassium-iodide-critical-component-nuclear-emergency-preparedness <div class="copyright">This article is copyrighted by GreenMedInfo LLC, 2024<br/><strong><a href="/greenmedinfocom-re-post-guidelines">Visit our Re-post guidelines</a></strong></div><p><img alt="" src="//cdn.greenmedinfo.com/sites/default/files/ckeditor/jarret@greenmedinfo.com/images/3(2).png" style="width: 600px; height: 600px;" /></p> <p><em><strong><span style="font-size:18px;"><span style="font-family: Verdana; letter-spacing: 0px;">In a nuclear crisis, this cheap mineral supplement could save your thyroid.</span></span></strong></em></p><p><a href="https://greenmedinfo.com/blog/potassium-iodide-critical-component-nuclear-emergency-preparedness" target="_blank">read more</a></p> https://greenmedinfo.com/blog/potassium-iodide-critical-component-nuclear-emergency-preparedness#comments Hyperthyroidism: Prevention Potassium Iodide Health Guide: Chemical Exposures potassium Thyroid Wed, 24 Jan 2024 17:00:00 +0000 GMI reporter 286939 at https://greenmedinfo.com Statin Drugs Linked to Thyroid Cancer in Women https://greenmedinfo.com/blog/statin-drugs-linked-thyroid-cancer-women <div class="copyright">This article is copyrighted by GreenMedInfo LLC, 2020<br/><strong><a href="/greenmedinfocom-re-post-guidelines">Visit our Re-post guidelines</a></strong></div><p class="rtecenter"><img alt="Statin Drugs Linked to Thyroid Cancer in Women" src="//cdn.greenmedinfo.com/sites/default/files/ckeditor/Sayer Ji/images/thyroid_cancer_female_statin.jpg" style="height: 399px; width: 600px;" /></p> <p><span style="font-size:18px;"><em><strong>So, you have been told to 'lower your cholesterol' with drugs.
