Durante el proceso de desconcentración de la UAEM, se crearon las Unidades Académicas y Centros Universitarios para brindar el servicio de educación a más jóvenes en todo el Estado de México, este Centro Universitario fue uno de los primeros y a sus veinte años de existencia se está consolidando como uno de los mejores. Es en los últimos años que se ha venido impulsando la investigación al contar con cuerpos académicos, en formación y en consolidación, con infraestructura de primera tanto en equipo como en laboratorios especializados, con profesores de tiempo completo que participan en congresos, seminarios y presentan publicaciones en revistas indexadas. Por ello para celebrar esos veinte años de existencia de esta honorable institución, se planeó la compilación de esta obra que es parte del quehacer multidisciplinario en investigación y docencia como parte del Plan de Desarrollo 2013-2017, de esta administración. Esta obra reúne investigaciones tanto de profesores como de alumnos desde las diferentes ramas del saber en las que se inscriben sus siete licenciaturas, Actuaría, Administración, Contaduría, Derecho, Economía, Relaciones Económicas Internacionales e Informática Administrativa, tanto presencial como a distancia, así como sus tres ingenierías, Industrial, en Computación y Sistemas y Comunicaciones, así como gracias a la vinculación y colaboración académico – científica que se tiene con otras instituciones de educación superior a nivel nacional, como el Instituto Tecnológico de Orizaba, la Universidad Autónoma de San Luis Potosí, la Universidad Nacional Autónoma de México, la Universidad Autónoma Metropolitana, Universidad Politécnica de Victoria, el Instituto Politécnico Nacional entre otras. En el capítulo 1 se abordan seis temáticas diferentes de vanguardia en el área de las Ingenierías, en los capítulos 2 y 3 se incluyen temas de interés y gran relevancia en materia de ciencias sociales, política y economía. Se hace extensivo un reconocimiento para todos los que participaron tanto en la revisión de los trabajos, como en la compilación del producto final de este Libro intitulado “Desarrollo Multidisciplinario en Investigación y Docencia del Centro Universitario UAEM Valle de México”

Higher levels of glutamate in the associative-striatum of subjects with prodromal symptoms of schizophrenia and patients with first-episode psychosis

The glutamatergic and dopaminergic systems are thought to be involved in the pathophysiology of schizophrenia. Their interaction has been widely documented and may have a role in the neurobiological basis of the disease. The aim of this study was to compare, using proton magnetic resonance spectroscopy (1H-MRS), glutamate levels in the precommissural dorsal-caudate (a dopamine-rich region) and the cerebellar cortex (negligible for dopamine) in the following: (1) 18 antipsychotic-naïve subjects with prodromal symptoms and considered to be at ultra high-risk for schizophrenia (UHR), (2) 18 antipsychotic-naïve first- episode psychosis patients (FEP), and (3) 40 age- and sex- matched healthy controls. All subjects underwent a 1H-MRS study using a 3Tesla scanner. Glutamate levels were quantified and corrected for the proportion of cerebrospinal fluid and percentage of gray matter in the voxel. The UHR and FEP groups showed higher levels of glutamate than controls, without differences between UHR and FEP. In the cerebellum, no differences were seen between the three groups. The higher glutamate level in the precommissural dorsal-caudate and not in the cerebellum of UHR and FEP suggests that a high glutamate level (a) precedes the onset of schizophrenia, and (b) is present in a dopamine-rich region previously implicated in the pathophysiology of schizophrenia.peer-reviewe

Panel 4 – Modern Institutional Networks Visualize Early Modern Archives: The Case of the Relaciones Geográficas y Topográficas

The 16th-century Relaciones Geográficas y Topográficas allow us to delve into archival interdependence then and now. The Relaciones endeavored to describe and map hundreds of municipalities in the Spanish Empire in response to a standard questionnaire. The project was remarkably successful in gathering information. Although we have yet to fully grasp how this information was put to use, we do know that it circulated throughout imperial archival networks. As such, the Relaciones become a representative case study for understanding archival networks as mechanisms to make knowledge possible and visible in both the past and the present. Invited scholars and archivists will discuss the challenges involved in gathering vast amounts of documentation hosted by dozens of archives worldwide. They will do so to highlight the processes behind reconstructing the archival and epistemological networks that this corpus evidences, and showcase the pedagogical and research potential of digital tools that necessarily must be developed through inter-institutional collaboration.Teresa Lozano Long Institute of Latin American Studies; Latin America Initiative; Institute for Historical Studies; Not Even PastLatin American Studie

Imaging techniques for assessing hepatic fat content in nonalcoholic fatty liver disease

Nonalcoholic fatty liver disease (NAFLD), an emerging clinical entity with worldwide recognition, is today the most common cause of abnormal liver function tests among adults in the United States. In Mexico City, its prevalence has been reported by our group to be around 14%, but its incidence is higher in the hispanic population in the United States (hispanic population 45%, white population 33%, black population 24%). The main issues in the diagnosis, follow-up, and management of NAFLD are our limited understanding of its pathophysiology and the difficulties involved in developing a noninvasive diagnostic method. Several imaging techniques can detect fatty infiltration of the liver, each with its own advantages and disadvantages. Ultrasound is still in the first option for diagnosis, but its accuracy depends on the operator and the patient’s features. Computed tomography can detect hepatic fat content, but only at a threshold of 30%, and it involves ionizing radiation. Magnetic resonance (MR) spectroscopy is probably the most accurate and fastest method of detecting fat, but it is expensive and the necessary software is still not easily available in most MRI units. MR elastography, a new technique to detect liver stiffness, has not been demonstrated to detect NAFLD, and is still undergoing research in patients with hepatitis and cirrhosis. In conclusion, all these imaging tools are limited in their ability to detect coexisting inflammation and fibrosis. In this review, we discuss the radiological techniques currently used to detect hepatic fat content

Dung removal increases under higher dung beetle functional diversity regardless of grazing intensification

Dung removal by macrofauna such as dung beetles is an important process for nutrient cycling in pasturelands. Intensification of farming practices generally reduces species and functional diversity of terrestrial invertebrates, which may negatively affect ecosystem services. Here, we investigate the effects of cattle-grazing intensification on dung removal by dung beetles in field experiments replicated in 38 pastures around the world. Within each study site, we measured dung removal in pastures managed with low- and high-intensity regimes to assess between-regime differences in dung beetle diversity and dung removal, whilst also considering climate and regional variations. The impacts of intensification were heterogeneous, either diminishing or increasing dung beetle species richness, functional diversity, and dung removal rates. The effects of beetle diversity on dung removal were more variable across sites than within sites. Dung removal increased with species richness across sites, while functional diversity consistently enhanced dung removal within sites, independently of cattle grazing intensity or climate. Our findings indicate that, despite intensified cattle stocking rates, ecosystem services related to decomposition and nutrient cycling can be maintained when a functionally diverse dung beetle community inhabits the human-modified landscape.info:eu-repo/semantics/publishedVersio
