Efecto de la adición de antioxidantes sobre la motilidad espermática post-criopreservación y fertilidad del semen de peces

La criopreservación de semen produce daños celulares a nivel de membranas plasmáticas, mitocondria y ADN, debido principalmente a la formación de cristales de hielo intra y extracelulares, así como al estrés osmótico y oxidativo generado. Para minimizar estos daños se utilizan medios diluyentes que simulan las características fisiológicas del semen y contienen sustancias crioprotectoras, las cuales con ayuda de algunos antioxidantes proporcionan una mayor supervivencia espermática post-descongelación y mejoría de las tasas de motilidad y fertilidad. La adición de antioxidantes enzimáticos como superóxido dismutasa, catalasa y peróxidasa durante el proceso de criopreservación de células espermáticas en peces, no favorece las tasas de motilidad espermática post-descongelación ni de fertilización en las especies trucha arco iris y de arroyo, mientras que los no enzimáticos (methylenediphosphonic- acid/MDPA, butil-hidroxitolueno/BHT, cisteína, propóleo, ácido ascórbico, lisina y carnitina) las mejoran de forma significativa en especies como esturión beluga, carpa común, esturión ruso y trucha arco iris. Los antioxidantes producen diversos efectos especie-específicos tanto en variables de calidad espermática como fertilidad y su efectividad depende de la concentración y el medio diluyente utilizado. Se concluye que la utilización de antioxidantes no enzimáticos en la criopreservación de semen de especies acuícolas como carpa común, esturión y trucha, resulta indispensable para mejorar la motilidad y fertilidad espermática.

Universidad saludable, una reflexión frente al bienestar integral en la comunidad

This article is aimed at reflecting on healthy lifestyles in a university environment and how this affects the well-being and integral health of its community. The transition from adolescence to adulthood exposes the human being to different factors of risk, coexistence, healthy or unhealthy lifestyles and habits can affect your health, for this reason it is necessary to design strategies and lines of research to prevent and / or mitigate the negative effects of exposure to these risk factors in adolescents and adults who are part of a higher educational environment. In such a way that it is necessary to generate a society aware that in the university context there are a series of relationships that impact on the integral health of people and must be rethought from their daily actions and behaviors, from the curriculum and from institutional policies, seeking a transforming intention to generate healthy environments in society.Este artículo se orienta a realizar una reflexión sobre estilos de vida saludable en un entorno universitario y como este incide en el bienestar y la salud integral de su comunidad. La transición de la edad adolescente a la edad adulta expone al ser humano a diferentes factores de riesgo, la convivencia, estilos y hábitos de vida saludables o poco saludables pueden afectar su salud, por tal razón se hace necesario el diseño de estrategias y líneas de investigación para prevenir y/o mitigar los efectos negativos de la exposición a estos factores de riesgo en los adolescentes y adultos que hacen parte de un entorno educativo superior. De tal forma, que es necesario generar una sociedad consciente de que en el contexto universitario se da una serie de relaciones que impactan en la salud integral de las personas y se deben replantear desde sus acciones y comportamientos cotidianos, desde el currículo y           desde las políticas institucionales, buscando una intención trasformadora en generar ambientes saludables en la sociedad

Uso de inhibidores de la bomba de protones y antagonistas de los receptores H2 de histamina como profilaxis en úlceras por estrés: ¿una práctica justificada?

La introducción de los moduladores de acidez gástrica como profilaxis contra las úlceras por estrés en pacientes críticos se ha ido convirtiendo en una práctica de rutina tanto en la unidad de cuidados intensivos como fuera de esta; sin embargo, el desconocimiento de la fisiopatología de la enfermedad, las indicaciones de uso de moduladores de pH como profilácticos, los riesgos asociados a la prescripción indiscriminada y de las guías disponibles sobre esta práctica han llevado a un uso descontrolado de medicamentos como omeprazol y ranitidina, lo cual aumenta los costos para los hospitales y predispone a los pacientes a presentar enfermedades como neumonía. Con el objetivo de revisar los factores de riesgo asociados a esta patología, la eficacia de esta medida, sus indicaciones y posibles complicaciones tanto dentro como fuera de las unidades de cuidados intensivos, se realizó una revisión de la literatura. Esta incluyó artículos disponibles en diferentes bases de datos que hicieran referencia al manejo profiláctico de úlceras por estrés desde 1980 hasta 2014. Se encontró que, según la literatura actual, el uso de la profilaxis contra úlceras por estrés es una práctica muy debatida en el caso de los pacientes críticos y, lo que es más importante, en los no críticos aún no existen recomendaciones de uso o factores de riesgo establecidos. Por esta razón, la extrapolación de esta conducta a pacientes fuera de la unidad de cuidados intensivos es injustificada hasta el moment

Interaction standards for biophysics: anti-lysozyme nanobodies

From Springer Nature via Jisc Publications RouterHistory: received 2020-10-14, rev-recd 2021-03-01, registration 2021-03-22, accepted 2021-03-22, pub-electronic 2021-04-11, online 2021-04-11, pub-print 2021-05Publication status: PublishedFunder: Wellcome Trust; doi: http://dx.doi.org/10.13039/100004440; Grant(s): 203128/Z/16/ZAbstract: There is a significant demand in the molecular biophysics community for robust standard samples. They are required by researchers, instrument developers and pharmaceutical companies for instrumental quality control, methodological development and in the design and validation of devices, diagnostics and instrumentation. To-date there has been no clear consensus on the need and type of standards that should be available and different research groups and instrument manufacturers use different standard systems which significantly hinders comparative analysis. One of the major objectives of the Association of Resources for Biophysical Research in Europe (ARBRE) is to establish a common set of standard samples that can be used throughout the biophysics community and instrument developers. A survey was circulated among ARBRE members to ascertain the requirements of laboratories when using standard systems and the results are documented in this article. In summary, the major requirements are protein samples which are cheap, relatively small, stable and have different binding strengths. We have developed a panel of sdAb’s or ‘nanobodies’ against hen-egg white lysozyme with different binding strengths and suitable stability characteristics. Here we show the results of the survey, the selection procedure, validation and final selection of a panel of nanobody interaction standards

Strategi of linking of the university with the socio- economic context as a training student way

Currently one of the fundamental processes in public and private universities is the linking process with the socioeconomic context as an important way to train professionals that society requires. While more efficient it is, greater advantages and benefits are for the different stakeholders, particularly students. The linking at the Faculty of Mechanical and Electrical Engineering (FIME) of the University of Nuevo León State (UANL) of Mexico with industry and society in general is a process that, since its conception in 1960, has served as a driver process for important achievements, although, as a dynamic and multifactorial process requires constant improvement. This improvement must be based on knowledge of its actual state. The aim of this paper is to analyze the current situation and perspective of that process in order to develop strategies that give advantage to the integral training that favors the interrelation of personal and professional training of the future engineers. The methodology used for this study combines methods and techniques of the empirical and theoretical levels such as: analysis, synthesis, historical and logical, and surveys of employers, teachers and students

History of social work ? recuperating a history of women.

Este texto tem como objetivo resgatar a participa??o feminina na constitui??o da hist?ria do Servi?o Social, dando visibilidade aos caminhos percorridos e aos pap?is desempenhados por algumas mulheres. Para isso, analisamos o caso das pioneiras da Escola de Servi?o Social de Niter?i, da Universidade Federal Fluminense (ESSN/UFF). O resgate de suas falas, atrav?s da hist?ria oral, foi o caminho metodologicamente tra?ado. Iniciamos o texto revisitando a hist?ria profissional para, em seguida, discutirmos acerca da necessidade de retirar da invisibilidade o protagonismo dessas mulheres ao construir uma profiss?o. Aprofundar essa dimens?o aponta para a import?ncia de pensarmos algumas quest?es, como a hist?ria das mulheres, o uso da dimens?o do g?nero e os feminismos na pesquisa acad?mica, o que compreendemos como um grande desafio que se coloca para a profiss?o.This text aims to recuperate the participation of women in the constitution of the history of social work, giving visibility to the paths covered and the roles played by women. In order to do this, we analyze the case of the pioneers of the Universidade Federal Fluminense?s Niter?i School of Social Service (ESSN/UFF). The recuperation of their speeches, through oral history, was the methodological route. We begin the text revisiting the professional history and then discuss the need to remove from invisibility the protagonism of these women when building a profession. Deepening this dimension points to the importance of thinking about some issues, such as the history of women, the use of the gender dimension and feminisms in academic research, which we understand as a great challenge for the profession

Enemies with benefits: parasitic endoliths protect mussels against heat stress

Positive and negative aspects of species interactions can be context dependant and strongly affected by environmental conditions. We tested the hypothesis that, during periods of intense heat stress, parasitic phototrophic endoliths that fatally degrade mollusc shells can benefit their mussel hosts. Endolithic infestation significantly reduced body temperatures of sun-exposed mussels and, during unusually extreme heat stress, parasitised individuals suffered lower mortality rates than nonparasitised hosts. This beneficial effect was related to the white discolouration caused by the excavation activity of endoliths. Under climate warming, species relationships may be drastically realigned and conditional benefits of phototrophic endolithic parasites may become more important than the costs of infestation

Pervasive mantle plume head heterogeneity: Evidence from the late Cretaceous Caribbean-Colombian oceanic plateau

In SW Colombia picritic pillow lavas and tuffs, as well as breccias composed of picritic clasts, occur interspersed with basalts of the Central Cordillera and represent accreted portions of the ∼90 Ma Colombian/Caribbean oceanic plateau (CCOP). We present new geochemical data for these picrites and high-MgO basalts from SW Colombia, along with new data from Deep Sea Drilling Project Leg 15 drill sites. The 40Ar/39Ar ages for the CCOP in the Central Colombian Cordillera range from 87 to 93 Ma. Both SW Colombia picrites and Leg 15 basalts are compositionally diverse and range from reasonably enriched ((La/Nd)n > 1 and (εNd)i +8.0). Nb/Y and Zr/Y systematics suggest that the depleted component is not depleted MORB mantle, but is an intrinsic part of the plume. The bulk of the CCOP compositions can be explained by mixing between this depleted mantle and a HIMU component. However, radiogenic isotope systematics indicate the presence of an EM2 (or possibly EM1) component within the plume. Mantle melt modeling suggests that the enriched magma types are the product of deeper, small degree melting of a pervasively heterogeneous plume comprising a refractory matrix with enriched streaks/blobs, whereas shallower, more extensive melting, results in the formation of relatively depleted magmas
