En este artículo se hará una revisión de las principales reformas administrativas efectuadas en el Gobierno del Estado de Veracruz, durante el periodo 2010-2016, realizando una investigación documental de los instrumentos de reforma utilizados para su implementación, con el objetivo de demostrar los resultados de la aplicación de las herramientas de la Nueva Gestión Pública, tales como la reducción de estructuras organizativas por parte del Gobierno del Estado de Veracruz, al cierre del sexenio 2010-2016.

In this article we will review the main administrative reforms carried out in the Government of the State of Veracruz, during the period 2010-2016, conducting documentary research of the reform instruments used for their implementation, with the aim of demonstrating the results of the application of the tools of the New Public Management, such as the reduction of organizational structures by the Government of the State of Veracruz, at the end of the six-year period 2010-2016. For this purpose, the descriptive method was used. The results show that the attempts to reduce the bureaucratic apparatus were unsuccessful.","PeriodicalId":494549,"journal":{"name":"UVSERVA","volume":"111 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139615612","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}

En los últimos años, la exposición a iones metálicos tóxicos ha ido en aumento debido a su consumo en alimentos, o por exposición ambiental u ocupacional, favoreciéndo patologías a nivel de sistema respiratorio, gastrointestinal, músculo esquelético y sistema nervioso. En órganos de la cavidad abdominal como el hígado y riñón, así como torácicos (pulmón y corazón), los efectos tóxicos son evidentes por la presencia de atrofia celular, edemas e inflamación. A nivel del Sistema Nervioso Central, la neurotoxicidad inducida por iones metálicos se caracteriza por estrés celular exacerbado, neurodegeneración y neuroinflamación. La falla órganica sistémica en combinanción con daño neuronal podría generar disfunción metabólica asociada a desregulación en la síntesis y liberación de neurotransmisores, lo cual podría derivar en alteraciones cognitivas y motoras.

However, heavy metal such as arsenic, cadmium, mercury and lead, which are key for soil dynamics, are not necessary to maintain homeostasis. On the contrary, exacerbated levels of heavy metals in cells induce morphophysiological alterations. Till date, exposure to metal ions has been increasing due to their consumption in junk food; due to environmental or occupational exposure favoring respiratory, gastrointestinal, skeletal muscle and neurological diseases. In peritoneal organs such as the liver and kidney, or thoracic organs for example in lung and heart, the toxic effects are evident by the presence of cell atrophy, edema and inflammation. At the central nervous system level, metal ion-induced neurotoxicity is characterized by increased cellular stress, neurodegeneration and neuroinflammation.
