Glicerolatos de metales alcalinos y sus posibles aplicaciones para el almacenamiento de hidrógeno

En este trabajo se reportan resultados computacionales obtenidos para la formación de glicerolatos de metales alcalinos (Li, Na y K), partiendo del principal subproducto de la producción de biodiesel, el glicerol. Los cálculos fueron realizados utilizando la Teoría de los Funcionales de la Densidad (DFT) con la base B3LYP/6­311(d). Se encontraron 4 configuraciones termodinámicamente estables para cada uno de los metales alcalinos, obteniéndose un total de 12 estructuras, en las cuales se sustituyen los protones de los hidroxilos de la molécula de glicerol por uno, dos o tres metales alcalinos. Adicionalmente, se presenta la formación de estructuras en forma de caja, a partir de la unión de dos glicerolatos trisustituidos, presentando así la posibilidad de incorporar dentro de su estructura moléculas de hidrógeno y adsorber moléculas adicionales alrededor de la misma. Todas las estructuras presentan viabilidad termodinámica y estabilidad, encontrándose como mínimo sobre la superficie de energía potencial

CoQ deficiency causes disruption of mitochondrial sulfide oxidation, a new pathomechanism associated with this syndrome

Coenzyme Q (CoQ) is a key component of the mitochondrial respiratory chain, but it also has several other functions in the cellular metabolism. One of them is to function as an electron carrier in the reaction catalyzed by sulfide:quinone oxidoreductase (SQR), which catalyzes the first reaction in the hydrogen sulfide oxidation pathway. Therefore, SQR may be affected by CoQ deficiency. Using human skin fibroblasts and two mouse models with primary CoQ deficiency, we demonstrate that severe CoQ deficiency causes a reduction in SQR levels and activity, which leads to an alteration of mitochondrial sulfide metabolism. In cerebrum of Coq9R239X mice, the deficit in SQR induces an increase in thiosulfate sulfurtransferase and sulfite oxidase, as well as modifications in the levels of thiols. As a result, biosynthetic pathways of glutamate, serotonin, and catecholamines were altered in the cerebrum, and the blood pressure was reduced. Therefore, this study reveals the reduction in SQR activity as one of the pathomechanisms associated with CoQ deficiency syndrome.This work was supported by grants from Ministerio de Economía y Competitividad, Spain, and the ERDF (SAF2013-47761-R, SAF2014-55523-R, RD12/0042/0011 and SAF201565786-R), from the Consejería de Economía, Innovación, Ciencia y Empleo, Junta de Andalucía (P10-CTS-6133), from the NIH (P01HD080642) and from the foundation “todos somos raros, todos somos únicos”.

Reforestation model with native plants of the Jaraba swamp through the IEP

La sequía en época de verano ocasionada por la acción directa del sol sobre las costas a causa de la perdida de vegetación en las mismas, es una realidad que afecta a las poblaciones ribereñas en la actualidad. Los programas de reforestación son herramientas útiles en la mejora de la calidad de vida de las diferentes partes del mundo afectadas por esta realidad. Este estudio tuvo como propósito diseñar un modelo de reforestación con plantas nativas de la ciénaga de Jaraba mediante la Investigación como Estrategia Pedagógica (IEP). La metodología se orientó bajo el enfoque cualitativo, utilizando el tipo de investigación acción, desde un diseño descriptivo, exploratorio. Para la recolección de datos se utilizaron técnicas como; análisis documental a partir de la implementación de un software que analiza las características de los arbustos y semillas propicias para la reforestación. La población estuvo conformada por cincuenta (50) estudiantes de la IED Antonio Bruges Carmona sede ERM de Jaraba del Municipio de Santa Ana Magdalena. Dando como resultados la creación de un vivero natural con diferentes especies de plantas seleccionadas para este modelo ecológico. Llegando a la conclusión que existe la necesidad de fortalecer la cultura ambiental por parte de los habitantes y visitantes en las orillas de la ciénaga, donde se vierte toda clase de desechos que difícilmente alcanzarán un nivel de degradación.The drought in summer time caused by the direct action of the sun on the coasts because of the loss of vegetation in them, is a reality that affects the riverside populations at present. Reforestation programs are useful tools in improving the quality of life in different parts of the world affected by this reality. The purpose of this study was to design a reforestation model with native plants of the Jaraba swamp through Research as a Pedagogic Strategy (IEP). The methodology was oriented under the qualitative approach, using the type of action research, from a descriptive, exploratory design. For the collection of data, techniques such as; documentary analysis based on the implementation of software that analyzes the characteristics of shrubs and seeds that are conducive to reforestation. The population was conformed by fifty (50) students of the IED Antonio Bruges Carmona ERM headquarters of Jaraba of the Municipality of Santa Ana Magdalena, giving as results the creation of a natural nursery with different species of plants selected for this ecological model. Reaching the conclusion that there is a need to strengthen the environmental culture on the part of the inhabitants and visitors on the banks of the swamp, where all kinds of waste that will hardly reach a level of degradation are poured

Post-Hospital Syndrome and Hyponatremia

Introduction: Post-hospital syndrome (PHS) is defined as a period of vulnerability during the first 30 days after a patient is discharged from hospital, in which multiple factors come into play. Hyponatremia is the most frequent hydroelectrolytic disorder in hospitalized patients and may be related to the appearance of PHS. Objective: The objective is to estimate the prevalence of PHS that is assessed as the rate of readmissions in the first 30 days after discharge, in patients with hyponatremia. Material and Methods: It is a descriptive observational study of patients with hyponatremia who were discharged from 1 September 2010 to 2 February 2020 at the Internal Medicine Service of the Hospital University of San Juan (Alicante, Spain). Results: Of the 25 included patients, 5 (20%) were readmitted within a month of discharge, after a mean of 11.4 days (standard deviation [SD] 5.1). The overall mortality of the study was 20% (n = 5), with one case of death in the first 30 days post-hospitalization (4%). In 12 patients (48%) the origin of the hyponatremia was undetermined. The most frequently recorded etiology for the condition was pharmacological (n = 7, 28%), and there was pronounced variability in its clinical and laboratory study. The most widely used corrective measure was drug withdrawal, in 16 patients (64%). Water intake restriction was the most common treatment after discharge (5 patients, 20%), followed by urea (2 patients, 8%), while tolvaptan was not used. Conclusion: Hyponatremia may be the cause of PHS, which could increase the rate of early readmission. Hyponatremia is an underdiagnosed and undertreated entity, so it is necessary to apply an appropriate system to optimize its management and, in future studies, to assess its impact on PHS

Characteristics and outcomes of adult patients in the PETHEMA registry with relapsed or refractory FLT3-ITD mutation-positive acute myeloid leukemia

This retrospective study investigated outcomes of 404 patients with relapsed/refractory (R/R) FMS-like tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD) acute myeloid leukemia (AML) enrolled in the PETHEMA registry, pre-approval of tyrosine kinase inhibitors. Most patients (63%) had received first-line intensive therapy with 3 + 7. Subsequently, patients received salvage with intensive therapy (n = 261), non-intensive therapy (n = 63) or supportive care only (n = 80). Active salvage therapy (i.e., intensive or non-intensive therapy) resulted in a complete remission (CR) or CR without hematological recovery (CRi) rate of 42%. More patients achieved a CR/CRi with intensive (48%) compared with non-intensive (19%) salvage therapy (p < 0.001). In the overall population, median overall survival (OS) was 5.5 months; 1- and 5-year OS rates were 25% and 7%. OS was significantly (p < 0.001) prolonged with intensive or non-intensive salvage therapy compared with supportive therapy, and in those achieving CR/CRi versus no responders. Of 280 evaluable patients, 61 (22%) had an allogeneic stem-cell transplant after they had achieved CR/CRi. In conclusion, in this large cohort study, salvage treatment approaches for patients with FLT3-ITD mutated R/R AML were heterogeneous. Median OS was poor with both non-intensive and intensive salvage therapy, with best long-term outcomes obtained in patients who achieved CR/CRi and subsequently underwent allogeneic stem-cell transplant.This study was supported by Centro de Investigación Biomédica en Red Cáncer (CIBERONC), Valencia, Spain [CB16/12/00284]

Alimentación y salud. Una experiencia de aprendizaje e innovación para la comunidad universitaria UCM a través de la Agenda 2030

Los desequilibrios políticos, económicos y sociales que presenta Colombia y la Región de Antioquia han derivado en altas tasas de inseguridad alimentaria. Este hecho, junto al elevado consumo de alimentos ultraprocesados en detrimento de la alimentación tradicional, está afectando gravemente la salud de la población. A todo ello hay que añadir el impacto del cambio climático y los eventos derivados extremos que comprometen la producción y distribución de alimentos. A través de cinco webinars, el público asistente conocerá de primera mano la importancia de la Cooperación Internacional al Desarrollo y la Agenda 20-30 como pretexto para afrontar la problemática de la inseguridad alimentaria en Antioquia, fenómeno que, pese a haberse hecho más evidente en los últimos años, permanece casi invisible por la mayoría de la población española. Asimismo, se hará especial hincapié en las políticas llevadas a cabo por Colombia para mejorar la alimentación, sin olvidar las consecuencias que están teniendo el cambio climático, los conflictos armados, los estragos generados por la pandemia por COVID-19 o la geopolítica mundial sobre la situación nutricional en la región colombiana
