Intracellular localization of a photosensitizer and chloride channel activation in electrocytes

Descripción del Articulo

The intracellular localization of a lipophilic alkyl long-chain tetraphenylporphyrin in electrocytes, Psammobatis extenta (Rajidae) is described. In contrast to the usual case, this porphyrin derivative was localized in electromotor nerves and in nuclei chromatin of electrocytes. Both structures exh...

En contraste con el comportamiento normal, este derivado de porfirina se localiza en los nervios electromotores y en los núcleos (cromatina) de los electrocitos. Ambas organelas presentaron una fluorescencia intensa. Sin embargo, la fluorescencia presentada por las mitocondrias fue débil. Estos datos son discutidos en relación con la muerte de los electrocitos de peces eléctricos de descarga débil. Adicionalmente, los datos obtenidos en el microanálisis por rayos-X (EDAX) sugieren la activación de los canales de cloro y catiónicos.Instituto Peruano de Energía Nuclearapplication/pdfengLima (Perú)PEinfo:eu-repo/semantics/openAccessInstituto Peruano de Energía NuclearRepositorio Institucional del Instituto Peruano de Energía Nuclearreponame:IPEN-Institucionalinstname:Instituto Peruano de Energía Nuclearinstacron:IPENElectrocitosIntracellularPecesAnalizadores de fluorescencia XCromatinaIntracellular localization of a photosensitizer and chloride channel activation in electrocytesinfo:eu-repo/semantics/articleORIGINAL_131-135_ Intracellular SANTIAGO - PRADO _r_.pdf_131-135_ Intracellular SANTIAGO - PRADO _r_.pdfapplication/pdf537348https://repositorio.ipen.gob.pe/bitstream/20.500.13054/360/1/_131-135_%20Intracellular%20SANTIAGO%20-%20PRADO%20_r_.pdf7704ce6329f28a667131a79ed3096c3eMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-8103https://repositorio.ipen.gob.pe/bitstream/20.500.13054/360/2/license.txt7ecf7b0639239de61a3a1ede9c397fecMD52TEXT_131-135_ Intracellular SANTIAGO - PRADO _r_.pdf.txt_131-135_ Intracellular SANTIAGO - PRADO _r_.pdf.txtExtracted texttext/plain14777https://repositorio.ipen.gob.pe/bitstream/20.500.13054/360/3/_131-135_%20Intracellular%20SANTIAGO%20-%20PRADO%20_r_.pdf.txt2a363a17dc4c6f3f63eb3a16d4dde1f0MD53THUMBNAIL_131-135_ Intracellular SANTIAGO - PRADO _r_.pdf.jpg_131-135_ Intracellular SANTIAGO - PRADO _r_.pdf.jpgGenerated Thumbnailimage/jpeg24479https://repositorio.ipen.gob.pe/bitstream/20.500.13054/360/4/_131-135_%20Intracellular%20SANTIAGO%20-%20PRADO%20_r_.pdf.jpg2b5b013b5758d50dc1d562af9b4ecc0aMD5420.500.13054/360oai:repositorio.ipen.gob.pe:20.500.13054/3602022-02-07 18:06:24.337Repositorio Institucional del Instituto Peruano de Energía Nuclearrepositorio@ipen.gob.peU2UgRGlzdHJpYnV5ZSBiYWpvIHVuYSBMaWNlbmNpYSBDcmVhdGl2ZSBDb21tb25zIEF0cmlidWNpw7NuLU5vQ29tZXJjaWFsLVNpbkRlcml2YXIgNC4wIEludGVybmFjaW9uYWwuCg==
