Exploring Health Science Students' Notions on Organ Donation and Transplantation: A Multicenter Study.
2020
The knowledge acquired during university education about organ donation and transplantation (ODT) decisively influences the information future health professionals transmit. This is important in ODT where the participation of the general public is essential to obtain organs. Objective To determine notions of Spanish medicine and nursing students on ODT and its relationship with attitude toward ODT. Methods and Design and design. We conducted a sociologic, multicenter, and observational study. The population for our study consisted of medical and nursing students in Spanish universities. Our database was the Collaborative International Donor Project, stratified by geographic area and academi…
Essential versus accessory aspects of cell death: recommendations of the NCCD 2015
2015
Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to as ?accidental cell death' (ACD). In most settings, however, cell death is initiated by a genetically encoded apparatus, correlating with the fact that its course can be altered by pharmacologic or genetic interventions. "Regulated cell death" (RCD) can occur as part of physiologic programs or can be activated once adaptive responses to perturbations of the extracellular or intracellular microenvironment fail. The biochemical phenomena that accompany RCD may be harnessed to…
La biología celular de GPBP (Goodpasture antigen binding protein)
2014
La enfermedad de Goodpasture (GP) es un proceso autoinmune exclusivamente humano caracterizado por una glomerulonefritis rápidamente progresiva y hemorragia pulmonar, causado por los autoanticuerpos que se depositan a lo largo de la membrana basal del glomérulo renal y el alveolo pulmonar. Los anticuerpos patógenos están dirigidos contra la región no-colagenosa del dominio C-terminal (NC1) de la cadena ¿3 del colágeno IV [a3 (IV)NC1 ] también llamado antígeno GP. Con el propósito de identificar proteínas que interaccionan con la región divergente N terminal del antígeno Goodpasture humano, se utilizaron de forma combinada un péptido sintético de 21 residuos que representa esta región y anti…
Defense Responses in Two Ecotypes of Lotus japonicus against Non-Pathogenic Pseudomonas syringae
2013
Lotus japonicus is a model legume broadly used to study many important processes as nitrogen fixing nodule formation and adaptation to salt stress. However, no studies on the defense responses occurring in this species against invading microorganisms have been carried out at the present. Understanding how this model plant protects itself against pathogens will certainly help to develop more tolerant cultivars in economically important Lotus species as well as in other legumes. In order to uncover the most important defense mechanisms activated upon bacterial attack, we explored in this work the main responses occurring in the phenotypically contrasting ecotypes MG-20 and Gifu B-129 of L. ja…
Citocentrifugación como un método adicional para estudiar celomitos de equinodermos: un enfoque comparativo que combina células vivas, preparaciones …
2021
Abstract Introduction: Echinoderm coelomocytes have traditionally been investigated through a morphological approach using light microscopy, which relies on the idea of constant cell shape as a stable character. However, this can be affected by biotic or abiotic conditions. Objective: To analyze if the consistency in cell morphology offered by the cytocentrifugation method, might be used as a convenient tool to study echinoderm coelomocytes. Methods: Cells of Echinaster (Othilia) brasiliensis (Asteroidea), Holothuria (Holothuria) tubulosa (Holothuroidea), Eucidaris tribuloides, Arbacia lixula, Lytechinus variegatus, and Echinometra lucunter (Echinoidea) were spread on microscope slides by c…
GPBP regula la respuesta inmune y es una diana terapéutica en cáncer
2017
GPBP es una serina/treonina cinasa no convencional exportable descubierta en nuestro laboratorio que fosforila al colágeno IV y cuya actividad ha sido relacionada por otros con la progresión del cáncer y la quimiorresistencia. Recientemente nuestro grupo de investigación ha puesto en evidencia que las células tumorales secretan GPBP al espacio extracelular (cGPBP) induciendo al colágeno IV a adoptar una estructura en red que facilita la transición epitelio-mesénquima que convierte a las células cancerosas en quimiorresistentes. cGPBP también ha sido relacionada por nosotros y otros con la patogénesis autoinmune e inflamatoria, respectivamente. Ahora en esta tesis demostraremos que cGPBP es …
Ex Vivo Treatment with a Polyphenol-Enriched Cocoa Extract Ameliorates Myocardial Infarct and Postischemic Mitochondrial Injury in Normotensive and H…
2016
Our objective was to determine the effects of a polyphenol-enriched cocoa extract (PCE) on myocardial postischemic alterations in normotensive (Wistar rats, W) and spontaneously hypertensive rats (SHR). Isolated hearts were submitted to 110 min of perfusion or 20 min stabilization, 30 min global ischemia, and 60 min reperfusion (R). Other hearts were treated with PCE at the onset of R. Infarct size, the reduced glutathione (GSH), and the expression of phospho-Akt, P-GSK-3β, and P-eNOS were assessed. In isolated mitochondria, the Ca2+-mediated response of mitochondrial permeability transition pore (mPTP), membrane potential (δψm), and superoxide production were determined. PCE decreased infa…

Prognostic value of the interaction between galectin-3 and antigen carbohydrate 125 in acute heart failure
2015
AIM:Galectin-3 (Gal-3) and carbohydrate antigen 125 (CA125) have emerged as robust prognostic biomarkers in heart failure. Experimental data have also suggested a potential molecular interaction between CA125 and Gal-3; however, the biological and clinical relevance of this interaction is still uncertain. We sought to evaluate, in patients admitted for acute heart failure, the association between plasma Gal-3 with all-cause mortality and the risk for rehospitalizations among high and low levels of CA125. METHODS AND RESULTS: We included 264 consecutive patients admitted for acute heart failure to the Cardiology Department in a third-level center. Both biomarkers were measured on admission. …
Capacidad protectora de la leche materna frente a las infecciones por norovirus
2012
En la actualidad se asume que la leche materna es el alimento de elección para el lactante hasta los seis meses de vida, recomendándose que se ofrezca más allá de este periodo junto con la alimentación complementaria. Las ventajas nutricionales de la lactancia materna han sido ampliamente estudiadas, si bien son menos conocidas sus propiedades defensivas. La capacidad protectora frente a la adquisición de infecciones es una propiedad que ofrece un gran beneficio al niño amamantado, especialmente frente a las infecciones producidas por norovirus (causa frecuente de infección intestinal en la infancia). Entre los efectores de esta función defensiva parecen estar implicados agentes de inmunida…
