    Resumen Estructurado: Introducción: La enfermedad de Freiberg (EF) es una osteocondrosis de las cabezas metatarsianas. Su etiología es multifactorial: trauma directo, microtraumas, enfermedades sistémicas, alteraciones de la vascularización. Entre las condiciones biomecánicas que han sido asociadas se encuentra el pie plano, un 1º metatarsiano corto, un 2 º metatarsiano largo y un 1º Metatarsiano hipermovil. Objetivo: El objetivo del estudio es conocer si existen cambios radiográficos que nos evidencien la existencia de un patrón metatarsal alterado o un cambio en pronación del retropié que sea compatible con un pie plano en los pacientes diagnosticados de enfermedad de Freiberg. Material y métodos: Se realizará un estudio descriptivo transversal. Se seleccionaran una radiografía en proyección dorsoplantar en carga por paciente. Para el acceso a las placas se solicitará permiso al comité ético del Servicio Galego De Saude (SERGAS). Como criterios de inclusión seleccionaremos a pacientes: con diagnosticado de Freiberg mediante placa radiografía en proyección dorsoplantar en carga. Como criterios de exclusión establecemos aquellas radiografías que por calidad de la misma no sea posible valorarlas. Las variables a estudiar son el ángulo de protrusión metatarsal, angulo HAV y ángulo astragalocalcaneo. Se creara una base de datos y se analizaran los mismos (Excel, SPSS). RESULTADOS ESPERADOS: Se espera encontrar alguna relación estadísticamente significativa entre la alteración de la parábola metatarsal y la enfermedad de Freiberg.Structured summary: Introduction: Freiberg’s disease osteochondrosis of the metatarsal heads. Its etiology is multifactorial: direct trauma, microtrauma, systemic diseases, and abnormal vascularity. Among the biomechanical conditions that have been associated flatfoot is a short 1st metatarsal, a long 2nd metatarsal and a hypermobile 1st Metatarsal. Objective:The objective of the study was to determine if there are radiographic changes that prove to us the existence of an altered pattern metatarsal or a change in rearfoot pronation that is compatible with a flat foot in patients diagnosed with Freiberg disease. Material and methods:A descriptive cross sectional study was performed. Dorsoplantar projection radiography in patient load will be selected. To access the license plates to the ethics committee Galego De Saude Service (SERGAS) is required. Inclusion criteria to select patients: diagnosed with Freiberg projection radiography using Plate dorsoplantar load. Exclusion criteria establish those quality radiographs that it is not possible to assess them. The variables studied are the angle of metatarsal protrusion HAV angle and talocalcaneal angle. It will create a database and the same (Excel, SPSS) were analyzed. Expected Results:We expect to find a statistically significant relationship between the alteration of the metatarsal parabola and Freiberg's disease.Traballo fin de grao (UDC.FEP). Podoloxía.

    This article belongs to the Special Issue Physical Education: Present and Future[Abstract] This paper presents a review of the research carried out internationally in recent years regarding textbooks, teaching materials, and the field of physical education. The objectives to which this article aims are as follows: To offer a compilation of current research papers published in the Scopus, Web of Science, and Dialnet databases and to provide a classification of the research lines undertaken on the subject. The information used is based on a review of studies listed in Scopus, Web of Science, and Dialnet. For this, a systematic review was carried out with the terms: “curricular resources”, “didactic materials”, “digital resources”, “educational resource”, “physical education”, and “textbooks”, allowing the selection of original articles, which included information on this line of research. For the literature review, only articles that presented scientific evidence were used, discarding merely descriptive articles or didactic experiences that were not investigated with the scientific protocol. A total of 589 articles were found, although after applying the review’s inclusion criteria, they were reduced to 54 articles. The investigations do not follow a common protocol and the researchers address multiple objectives in them, highlighting the studies on the implicit ideological discourse in the images of physical education textbooks. The results reveal a diversity of research, in particular, studies involving ideological discourse. Insofar as methodology, content analysis of textbooks and materials was the most common approac

    This study aimed to investigate the role of preproghrelin-derived peptides in adipogenesis. Immunocytochemical analysis of 3T3-L1 adipocyte cells showed stronger preproghrelin expression compared with that observed in 3T3-L1 preadipocyte cells. Insulin promoted this expression throughout adipogenesis identifying mTORC1 as a critical downstream substrate for this profile. The role of preproghrelin-derived peptides on the differentiation process was supported by preproghrelin knockdown experiments, which revealed its contribution to adipogenesis. Neutralization of endogenous O-acyl ghrelin (acylated ghrelin), unacylated ghrelin, and obestatin by specific antibodies supported their adipogenic potential. Furthermore, a parallel increase in the expression of ghrelin-associated enzymatic machinery, prohormone convertase 1/3 (PC1/3) and membrane-bound O-acyltransferase 4 (MBOAT4), was dependent on the expression of preproghrelin in the course of insulin-induced adipogenesis. The coexpression of preproghrelin system and their receptors, GHSR1a and GPR39, during adipogenesis supports an autocrine/paracrine role for these peptides. Preproghrelin, PC1/3, and MBOAT4 exhibited dissimilar expression depending on the white fat depot, revealing their regulation in a positive energy balance situation in mice. The results underscore a key role for preproghrelin-derived peptides on adipogenesis through an autocrine/paracrine mechanism

    The Obestatin/GPR39 System Is Up-regulated by Muscle Injury and Functions as an Autocrine Regenerative System

    Background: Satellite cell activation is orchestrated by several signals, which induce their differentiation into skeletal muscle fibers. Results: Obestatin and the GPR39 receptor exert an autocrine role on the control of myogenesis. Conclusion: Our data indicate that obestatin/GPR39 is an injury-regulated signal that functions as a myogenic regenerative system. Significance: Strategies to enhance obestatin-mediated signaling could be useful in treating trauma-induced muscle injuries and skeletal muscle myopathies

    La teoría de sistemas dinámicos cuantifica los estados y la evolución de los sistemas. Con base en esta teoría se creó una nueva metodología que cuantifica parejas ordenadas de frecuencias cardiacas en el espacio de fases de mediante la probabilidad y proporciones de la entropía, diferenciando clínicamente normalidad, enfermedad crónica, aguda, y evolución. Se registraron frecuencias cardiacas y latidos totales cada hora en 40 Holter de pacientes hospitalizados en la Unidad de Cuidados Coronarios, se realizó una simulación computacional para construir atractores caóticos y se evaluó la probabilidad, la entropía no equiprobable, y las proporciones de la entropía para la ocupación espacial de cada atractor, realizando comparaciones entre el diagnóstico clínico y el obtenido a través de la metodología físico matemática. Se evidenció que la metodología detecta en todos los casos el estado patológico de la dinámica, obteniendo valores de sensibilidad y especificidad de 100% y coeficiente Kappa de 1, evidenciando que es posible además establecer cuantitativamente la gravedad del mismo. Los resultados confirman que la autoorganización física y matemática de la dinámica cardiaca reflejada en el atractor dinámico geométrico, permite establecer predicciones de aplicación clínica en pacientes de la Unidad de Cuidados Coronarios

    Genetic Targeting of GRP78 in the VMH Improves Obesity Independently of Food Intake

    Recent data have demonstrated that the hypothalamic GRP78/BiP (glucose regulated protein 78 kDa/binding immunoglobulin protein) modulates brown adipose tissue (BAT) thermogenesis by acting downstream on AMP-activated protein kinase (AMPK). Herein, we aimed to investigate whether genetic over-expression of GRP78 in the ventromedial nucleus of the hypothalamus (VMH: a key site regulating thermogenesis) could ameliorate very high fat diet (vHFD)-induced obesity. Our data showed that stereotaxic treatment with adenoviruses harboring GRP78 in the VMH reduced hypothalamic endoplasmic reticulum ER stress and reversed vHFD-induced obesity. Herein, we also demonstrated that this body weight decrease was more likely associated with an increased BAT thermogenesis and browning of white adipose tissue (WAT) than to anorexia. Overall, these results indicate that the modulation of GRP78 in the VMH may be a target against obesity
