    This article is addressed from the strategic perspective in finances, its goal is to show recent technical equipment related to procedures/practices of financial analysis of prediction and its use in the management, and also to understand at what point there is an optimal capital structure. Forthisreason we construct a conceptual support based on trade-off theory and the study of techniques and tools that lead to measure the results obtained in a management period. We conclude that when the authors use statistics, they establish patterns that characterize organizations and that are treated in the field of prediction and description.El presente artículo es abordado desde la perspectiva estratégica en finanzas, el objetivo es mostrar el material técnico reciente sobre procedimientos/ prácticas de análisis financieros de predicción y su utilización en la gestión, así como entender en qué momento se da una estructura óptima de capital. Por tal razón se construye un soporte conceptual basado en la teoría del trade-off y el estudio de técnicas y herramientas que conduzcan a medir los resultados que se obtienen en un periodo de gestión. Se concluye que los autores, al hacer uso de la estadística, establecen patrones que caracterizan las organizaciones y que son tratados en el campo de la predicción y la descripción

    Purpose: This article presents a systematic review of philosophical thought about the beginnings of the solidarity economy in the international and national context. Description: The development of the global economy requires new settings for thinking and the praxis of cooperativism or solidarity economies in the dif ferent activities that constitute the work of human beings, i.e., politics, society, economics, and culture, among others. This article describes the development of cooperativism and the solidarity economy from their conception to their contribution to the improvement of the quality of life of human beings, in addition to providing a suitable setting for the approaches generated by the peace agreements in Colombia. Viewpoint: The article attempts to consider theoretical development from the different schools of thought that have arisen over time, from the concept of the solidarity economy as a response to the social crises that have accompanied civilization. Conclusions: Solidarity has historically been based on social development that seeks equity, justice, and sustainability for individuals. The description provided in this article allows us to establish the characterization of thinking about solidarity as a basis for the progress of modern communities.Propósito: el presente artículo realiza una revisión sistemática del pensamiento filosófico en función de los comienzos de la economía solidaria, en los contextos internacional y nacional. Descripción: Actualmente el desarrollo de la economía globalizada exige nuevos escenarios que involucren el pensamiento y la praxis en las diferentes actividades que constituyen el quehacer de los seres humanos. Punto de vista: en consecuencia el objetivo del artículo se fundamenta en dar una mirada al desarrollo teórico que se puede leer desde las diferentes corrientes expuestas en el tiempo en torno a la economía solidaria, como una respuesta a las crisis sociales que han acompaña  Propósito: o presente artigo apresenta uma revisão sistêmica do pensamento filosófico sobre os começos da economia solidária nos contextos internacional e nacional.

    Este artículo se deriva de la formulación de la línea de investigación en Información, Control y Gestión en su eje de identidad epistémico-disciplinal. Se realiza una reflexión acerca de la evolución del pensamiento administrativo y para ello se efectúa un recorrido por los autores representantes de las diferentes escuelas de pensamiento administrativo: Clásicas, Neoclásica,  Relaciones Humanas y Pensamiento Administrativo de Montreal, develando cómo cada una de ellas inserta el papel del ser humano en el desarrollo de las actividades empresariales y cómo éste se convierte en un aspecto clave de controversia.   Finalmente, se concluye que el rescate de los valores culturales, éticos y sociales de los seres humanos no pasa de ser una retórica, que no trasciende la realidad empresarial, y se dejan algunos elementos para tratar en trabajos futuros ABSTRACT This article derives from the formulation of the line of investigation on Information, Management and Control in its axis of disciplinal epistemic identity. A reflection is made about the evolution of the administrative thought, for which is done a going through the most representative authors of the different schools of administrative thought: Classic, neoclassic, Human Relations and Administrative Thought of Montreal, permiting to reveal how each of these ideas insert the human being’s role in the development of the enterprise activities and how this one becomes a key aspect of controversy. Finally, the conclusion is that the rescue of the cultural, ethical and social values of the human beings does not happen to be more than a rhetoric, that does not extend the enterprise´s reality, and some elements are left to be considered in future works

    The culture of the lobster Panulirus interruptus is limited due to the lack of knowledge that allow the completion of all larval stages. This work presents data on daytime and nightime oxygen consumption and ammonia excretion in phyllosoma I and II of the red lobster Panulirus interruptus reared in the lab at 21 °C and feeding with enriched Artemia nauplii. During starvation, the oxygen consumption by larvae phyllosoma dropped from 5.29 in the first hour to 3.54 mg O2 g-1h-1 after 14 h. The postabsorptive state was achieved after 13.5 h of starvation. This observation was taken into account to use starved larvae in our study. Oxygen consumption in the daytime was significantly higher than in the nightime in both larval stages. The levels of oxygen consumption (mg O2 g-1h-1) during daytime and nightime were: 4.28 and 3.66 in phyllosoma I and; 3.8 and 3.17 in phyllosoma II, respectively. There were no significant daytime/nightime differences of ammonia excretion: phyllosoma I excreted 0.011 to 0.095 mg NH4 g-1h-1; phyllosoma II excreted 0 to 0.65 mg NH4 g-1h-1. Oxygen consumption and ammonia excretion were significantly higher in phyllosoma I than in phyllosoma II. There were no significant differences between daytime and nightime The Oxygen-Nitrogen ratios of 59.1 to 422.4 obtained in both stages suggest a catabolism ranging from utilization of equal values of proteins and lipids to utilization of lipids and carbohydrates.El cultivo de la langosta Panulirus interruptus está limitado por la ausencia de conocimientos que permitan concluir el ciclo larval con eficiencia. Este trabajo presenta resultados sobre la respiración y la excreción de larvas filosomas tempranas cultivadas en el laboratorio a 21 °C y alimentadas con nauplios de Artemia enriquecidos con microalgas Isochrysis sp. y Chaetoceros muelleri. El estado postabsortivo se obtuvo después de 13.5 horas de ayuno. Durante el ayuno, el consumo del oxígeno de las larvas disminuyó de 5.29 mg O2 g-1 h-1 en la primera hora a 3.54 mg O2 g-1 h-1 después de 14 horas. El consumo de oxígeno diurno fue significativamente mayor que el nocturno en las filosomas de los estadios I y II. Los niveles medios del consumo de oxígeno durante día y noche fueron: 4.28 y 3.66 en filosoma I, y 3.8 y 3.17 en filosoma II, respectivamente. No se encontraron diferencias significativas en la excreción de amoniaco entre el día y la noche: las filosomas I excretaron de 0.011 a 0.095 mg NH4 g-1 h-1 , y las filosomas II, de 0-0.65 mg NH4 g-1 h-1 . Las tasas de consumo de oxígeno y excreción del amoniaco fueron significativamente más altas en filosoma I que en filosoma II. No se detectaron diferencias significativas entre el día y la noche, en la relación O: N (oxígeno:nitrógeno). Las relaciones O:N de 59.1 a 422.4 obtenidas en ambas fases indican un catabolismo que va de la utilización de mezclas iguales de proteínas y lípidos a la utilización de lípidos e hidratos de carbono

    Metabolic Impairments Caused by Pesticides in Mammals and Their Interactions with Other Pollutants

    The biological systems are exposed to a complex environment in which the contaminants can interact in a synergistic/antagonistic fashion and for this reason, the study of “chemical cocktails” is of great interest to fully understand the final biological effect. To evaluate the final biological response of a pollutant, it is essential to have an adequate analytical methodology that allows the correct monitoring of environmental systems in order to establish their quality, and, when appropriate, the application of corrective measures. Undoubtedly, massive methods “the omics” are among the most efficient current tools. To this end, transcriptomics, proteomics, metabolomics and chemical speciation can provide very useful information, mainly when they are combined. However, the combination of proteomics with metabolomics has some drawbacks as the temporal space is different (i.e. metabolomics gives information about what happens right now, but it can be related with numerous post-translational modifications happened previously). In this sense, it seems that the combination of genomics with metabolomics is easier. Thus, when metabolomics data are interpreted in combination with genomic, transcriptomic and proteomic results, in the so-called systems biology approach, a holistic knowledge of the organism/process under investigation can be achieved

    Predictive Value of Serum Antibodies and Point Mutations of AQP4, AQP1 and MOG in A Cohort of Spanish Patients with Neuromyelitis Optica Spectrum Disorders

    The detection of IgG aquaporin-4 antibodies in the serum of patients with Neuromyelitis optica (NMO) has dramatically improved the diagnosis of this disease and its distinction from multiple sclerosis. Recently, a group of patients have been described who have an NMO spectrum disorder (NMOsd) and who are seronegative for AQP4 antibodies but positive for IgG aquaporin-1 (AQP1) or myelin oligodendrocyte glycoprotein (MOG) antibodies. The purpose of this study was to determine whether AQP1 and MOG could be considered new biomarkers of this disease; and if point mutations in the gDNA of AQP4, AQP1 and MOG genes could be associated with the etiology of NMOsd. We evaluated the diagnostic capability of ELISA and cell-based assays (CBA), and analyzed their reliability, specificity, and sensitivity in detecting antibodies against these three proteins. The results showed that both assays can recognize these antigen proteins under appropriate conditions, but only anti-AQP4 antibodies, and not AQP1 or MOG, appears to be a clear biomarker for NMOsd. CBA is the best method for detecting these antibodies; and serum levels of AQP4 antibodies do not correlate with the progression of this disease. So far, the sequencing analysis has not revealed a genetic basis for the etiology of NMOsd, but a more extensive analysis is required before definitive conclusions can be drawn.Ministerio de Economía y CompetitividadFEDER (Grants PI16/01249 y PI16/00493

    Comparative analysis for the presence of IgG anti-aquaporin-1 in patients with NMO-Spectrum disorders

    Detection of IgG anti-Aquaporin-4 (AQP4) in serum of patients with Neuromyelitis optica syndrome disorders (NMOSD) has improved diagnosis of these processes and differentiation from Multiple sclerosis (MS). Recent findings also claim that a subgroup of patients with NMOSD, serum negative for IgG-anti-AQP4, present antibodies anti-AQP1 instead. Explore the presence of IgG-anti-AQP1 using a previously developed cell-based assay (CBA) highly sensitive to IgG-anti-AQP4. Serum of 205 patients diagnosed as NMOSD (8), multiple sclerosis (94), optic neuritis (39), idiopathic myelitis (29), other idiopathic demyelinating disorders of the central nervous system (9), other neurological diseases (18) and healthy controls (8), were used in a CBA over fixed HEK cells transfected with hAQP1-EGFP or hM23-AQP4-EGFP, treated with Triton X-100 and untreated. ELISA was also performed. Analysis of serum with our CBA indicated absence of anti-AQP1 antibodies, whereas in cells pretreated with detergent, noisy signal made reliable detection impossible. ELISA showed positive results in few serums. The low number of NMOSD serums included in our study reduces its power to conclude the specificity of AQP1 antibodies as new biomarkers of NMOSD. Our study does not sustain detection of anti-AQP1 in serum of NMOSD patients but further experiments are expected
