Understanding how animals respond to stressors is critical for effective conservation. The present study aimed to evaluate the physiological recovery of the Shortnose Guitarfish, Zapteryx brevirostris after being incidentally captured by artisanal fleets and compared it to guitarfish with delayed mortality. Moreover, the study aimed to test the efficiency of a rehabilitation protocol for the species. To this end, individuals landed alive were transported to the rehabilitation facilities and kept in tanks under monitoring for 3 days. Physiological markers indicative of allostatic overload (i.e., lactate and phosphorus) and energy metabolism (i.e., glucose and β‐hydroxybutyrate) were assessed in the serum of the studied guitarfish: right after gillnet capture (i.e., post‐capture) and on rehabilitation (i.e., pre‐monitoring, post‐monitoring, as well as guitarfish that deceased during monitoring – post‐mortem). Results showed that the transportation and additional handling employed in the rehabilitation protocol did not increase the stress response, pointing to its potential efficacy in recovering debilitated, incidentally caught guitarfish before release. As for recovery success of monitored guitarfish, lactic acidosis was fully reverted after a 3‐day rest period, as was allostatic overload. The same was not observed in recovery failure. Correlation tests revealed key relationships between physiological markers, shedding light on how physiological pathways help guitarfish cope with capture and handling stress. This study highlights the valuable application of conservation physiology principles to fisheries management of this endemic and threatened guitarfish species. [ABSTRACT FROM AUTHOR]

Objective To describe the microsurgical anatomy and the physiology of the endolymphatic sac (ES) that a neurosurgeon should know.

Plant yield is directly affected by the increase in air temperature and the water availability in the soil. Therefore, the objective with this study was to evaluate the physiological and productive performance of sorghum cultivars as a function of soil water availability and temperature at the cultivation time. The research was carried out at Embrapa Semi-Arid, municipality of Petrolina, Pernambuco state, Northeast region, Brazil, with planting in June 2021 and January 2022. The experiment was conducted in a randomized block design with a 2 × 6 × 4 factorial arrangement, with two growing seasons (season 1: planting in June; season 2: planting in January), six sorghum cultivars (AGRI002E, BRS 716, BRS 506, SF 15, IAC Santa Elisa and BRS Ponta Negra) and four water availability levels (25, 50, 75, and 100%), with four replications. The following variables were evaluated: total dry mass, water use efficiency, photosynthesis, stomatal conductance, transpiration and leaf temperature. The SF 15 and BRS Ponta Negra cultivars produced the highest amount of total dry mass when planted in June, with maximum temperatures ranging from 26 to 34 °C and 100% water availability. The AGRI002E cultivar showed higher dry mass production, photosynthesis, stomatal conductance and leaf transpiration rates among the other cultivars in season 2, with 100% of soil water retention capacity, demonstrating adaptation to the increase in temperature.

A pesar de que la contribución más notable en el campo de la fisiología experimental en Argentina se atribuye a Bernardo Alberto Houssay, este estudio destaca la importancia de los esfuerzos previos y fundamentales de Grandis y Ducceschi, dos profesores italianos cuyo trabajo en Buenos Aires y Córdoba sentó las bases para la investigación y la enseñanza de esta disciplina. El trabajo detalla cómo, en 1904, la llegada de Valentín Grandis a la UNC marcó el inicio formal de la enseñanza y práctica de la fisiología experimental en la institución, seguida por la incorporación de Virgilio Ducceschi, quien continuó y expandió el legado de Grandis. La labor de estos dos maestros italianos no solo involucró la instalación de un laboratorio de vanguardia sino también el establecimiento de una sólida base académica y científica que influiría en generaciones futuras de médicos e investigadores argentinos. A través de un análisis detallado de sus biografías, contribuciones científicas, y el impacto de su trabajo, este documento ilustra cómo Grandis y Ducceschi fueron figuras clave en el desarrollo de la ciencia médica en Argentina, particularmente en el ámbito de la fisiología experimental. Además, el estudio resalta la importancia de su enfoque educativo y su capacidad para formar discípulos que continuarían sus investigaciones, asegurando así la permanencia de su legado en la Universidad Nacional de Córdoba y en la ciencia argentina en general. En conclusión, el presente trabajo reivindica y celebra las contribuciones de Valentín Grandis y Virgilio Ducceschi al inicio de la investigación y experimentación en fisiología y química biológica en la UNC, subrayando su importancia en el avance de la medicina y la ciencia en Argentina.

Resumen: La oxigenación extracorpórea mediante membrana (ECMO, por sus siglas en inglés) es una técnica utilizada en pacientes con insuficiencia respiratoria y/o cardíaca catastrófica. En este artículo, se revisan las diferencias y similitudes fisiológicas entre el ECMO y la función cardiopulmonar normal. Se describen los procesos involucrados en la transferencia gaseosa, así como los factores que influyen en la eficiencia de la oxigenación y eliminación del dióxido de carbono. Se hace énfasis en la relevancia clínica de la fisiología del ECMO para la atención de pacientes críticos. Abstract: Extracorporeal membrane oxygenation (ECMO) is used in patients with catastrophic respiratory and cardiac failure. In this article, the physiologic similarities and differences between normal and ECMO cardiopulmonary function are reviewed. The processes involved in gas transfer are described, as well as the factors that influence the efficiency of oxygenation and elimination of carbon dioxide. Emphasis is placed on the clinical relevance of the physiology of ECMO for critically ill patients.

Resumo: Este artigo mostra que o imoralismo não resume a posição nietzschiana. Nietzsche fez uso das categorias éticas - notadamente as categorias de “dever”, de “justiça” ou de “compaixão” - em sua ótica de propor uma nova filosofia do corpo. Por essa tentativa de fazer uma moralidade proteiforme recair no coração mesmo das trocas orgânicas, Nietzsche reforma a moral sobre bases fisiológicas. Esse gesto visa reconstruir as leis de ação.

Introducción: a lo largo de la historia se han desarrollado sistemas de conciencia que han permitido interpretar el entorno de una forma más acertada. En nuestra especie, dichos sistemas facilitaron que se dominara la materia y que se desarrollaran aspectos neurofisiológicos tan complejos que nos posibilitan preguntarnos sobre nuestro origen, fisiología y existencia. Materiales y métodos: se recolectaron datos de varias fuentes, de diversas bibliotecas, que incluyen neuroanatomía, psicología y etología, así como datos obtenidos de la geología, la paleontología y la arqueología que nos orientan para reconstruir la historia filogenética y relacionarla con los conocimientos actuales de neurología y psiquiatría. Resultados: en las especies, la aparición de sistemas complejos, como el sistema nervioso, expresa su mayor exponente en el sistema nervioso humano. Esto, a partir de estrategias evolutivas estables, ha abierto el camino para desarrollar sistemas de conciencia más sofisticados como el humano. Discusión: las diversas hipótesis que intentan explicar el origen de nuestro cerebro han revelado datos que permiten comprender e interpretar diferentes formas de conciencia, primitivas y complejas, que con gran dificultad permiten reconstruir dicho origen, desde diversos aspectos neurofisiológicos que nos llevan a intentar comprender la estructura misma de la psique, que parece desarrollarse funcional y filogenéticamente a partir de capas profundas hasta capas superficiales. Conclusiones: entendemos que la aparición del sistema nervioso y la conciencia tiene una historia, un proceso importante que entender para interpretar el origen de nuestro cerebro y su relación con la conciencia; sin embargo, aún quedan muchos interrogantes por interpretar.

No presente artigo, proponho examinar e explicitar a compreensão de Condillac da loucura e a relação desse fenômeno com o conceito de associação de ideias e com elementos de fisiologia. Nessa direção, concentro o escopo da investigação em duas obras do filósofo francês: o Ensaio sobre a origem dos conhecimentos humanos (1746) e o Dicionário de sinônimos (1951). Nos textos mencionados, o filósofo mobiliza uma concepção de loucura que está identificada com o desregramento da razão. O afastamento da razão, os erros e desvios do raciocínio encontram a sua chave explicativa no conceito de associação de ideias e na maneira com que essas se ligam na faculdade da imaginação. Todavia, no interior dessa explicação, se observa uma ambivalência acerca da fisiologia e do seu papel na configuração das experiências da loucura. Ora o filósofo atribui relevância aos argumentos de natureza fisiológica na compreensão das manifestações da loucura, ora relativiza a importância desses argumentos e a função da fisiologia na explicação dessas manifestações. Apesar dessa hesitação, fica estabelecido que a explicação condillaciana toma a associação de ideias como causa da loucura e não dissociada de um componente de natureza fisiológica. Uma vez identificada a gênese do desregramento da razão, o filósofo termina por sugerir um cuidado de ordem pedagógica como alternativa para prevenir a loucura e educar o espírito humano.

El objetivo de este estudio fue describir la cinemática, la coordinación de brazos y el consumo de oxígeno de nadadores con amputaciones, y comprobar la evolución de estos parámetros en dos vueltas (75-100 m y 175-200 m) de una prueba de 200 m estilo crol (T200). Participaron seis nadadores (cuatro hombres y dos mujeres) con amputaciones (edad: 30 ± 9.8 años). Se obtuvieron medidas antropométricas y se colocaron 19 marcadores en zonas predeterminadas del cuerpo para la posterior exploración de la T200. Los nadadores calentaron y luego realizaron la T200. La prueba se grabó en vídeo digital. Se procesaron las imágenes (software APAS) y se analizaron los vídeos en tres dimensiones (3D). A partir de las imágenes, se obtuvieron datos cinemáticos (frecuencia y longitud medias de brazada, velocidad de nado e índice de brazada) y coordinativos (índice de coordinación). Durante la T200, se midió el consumo de oxígeno (VO2) de cada respiración (analizador de gases portátil) y se identificó su valor su valor de pico (VO2pico). Con el fin de comparar los datos entre las vueltas, se utilizaron estadísticas descriptivas y la prueba t de Student para los datos emparejados. El rendimiento de los nadadores evaluados fue de 197.8 ± 24.7 s. La frecuencia, la longitud, la velocidad y el índice de brazada fueron, respectivamente, 41.0 ± 5.1 ciclos/min, 1.5 ± 0.3 m, 0.98 ± 0.02 m/s y 1.67 ± 0.59m2/s. En general, la coordinación se produjo en la captura con un consumo pico de oxígeno de 43.6 ± 8.0 ml.kg-1.min-1. Las variables cinemáticas y la coordinación no cambiaron entre las vueltas analizadas.

La adaptación fisiológica de los recién nacidos de la vida intrauterina a la extrauterina incluye cambios fisiológicos complejos. Para que se complete con éxito la transición fetal a neonatal, los recién nacidos deben lograr el aclaramiento de líquido pulmonar, la generación de CRF e inicio de la respiración, para permitir el intercambio de gases y la oxigenación de los tejidos. En este artículo se describen estos mecanismos, algunas bases del desarrollo pulmonar y de la circulación fetal; y las medidas que se requieren para asistir al recién nacido cuando no logran completar esta transición espontáneamente, lo que ocurre en el 5 al 10 % de los casos.

Día con día nos exponemos a obstáculos y desafíos para obtener así un beneficio; el narcisismo patológico implica importantes déficits en la calidad de vida y estrategias de mala adaptación al momento de hacer frente a decepciones o amenazas a la imagen positiva de sí mismo. El narcisismo y trastorno de personalidad narcisista se han descrito desde el psicoanálisis en 1898, el mito griego de Narciso, la filosofía del yo, y los libros de psiquiatría de la actualidad; sin embargo, su diagnóstico y tratamiento se han visto cegados por una escasa importancia al tema y su estudio. Se dice que todos los individuos pueden presentar un nar-cisismo normal; sin embargo, los individuos patológicamente narcisistas usualmente se preocupan o defraudan, e incluso se sienten amenazados ante las situaciones o personas que se presentan en su vida. Esta pato-logía incide en la calidad de vida de quienes la padecen y de quienes los rodean, de ahí la importancia de conocerla

Introduction: The role of oscillometry in interstitial lung disease (ILD) is still unclear. The main objective of our study was to describe the parameters determined by oscillometry in these patients and compare them with those obtained in conventional respiratory function tests. Material and methods: This was a cross-sectional observational study. Patients with no respiratory disease and patients being followed up for ILD in the specialist unit of Hospital Universitario de Getafe, Madrid were included. Results: A total of 45 individuals were analyzed. Fifteen had no respiratory disease, 15 were ILD patients with mild functional impairment, and another 15 were ILD patients with severe impairment. None of the participants had an obstructive pattern on spirometry.Comparison between the three groups showed statistically significant differences in the values of R5-19, reactance at 5 Hz and reactance at 11 Hz. No differences were observed between the three groups in Delta Xrs. The study showed a strong correlation between total and inspiratory reactance at 5 Hz and forced vital capacity and diffusing capacity for carbon monoxide. Conclusions: Our results suggest that the findings in ILD are characteristic of this disease and that they differ from those found in other diseases such as chronic obstructive pulmonary disease. It also seems that there are differences according to the degree of functional impairment of the patients. The results show a strong correlation with standard pulmonary function tests, so oscillometry could be a useful tool in patients with ILD who are unable to perform it, and could provide additional information. Resumen: Introducción: El papel de la oscilometría en la enfermedad pulmonar intersticial difusa (EPID) aún no está claro. El objetivo principal de nuestro estudio fue describir los parámetros determinados por oscilometría en estos pacientes y compararlos con los obtenidos en las pruebas de función respiratoria convencionales. Material y métodos: Se trata de un estudio observacional transversal. Se incluyeron tanto pacientes sin enfermedad respiratoria como pacientes con EPID en seguimiento en la unidad especializada del Hospital Universitario de Getafe, Madrid. Resultados: Se analizaron un total de 45 individuos. Quince no tenían ninguna enfermedad respiratoria, 15 eran pacientes con EPID y deterioro funcional leve, y otros 15 eran pacientes con EPID con deterioro grave. Ninguno de los participantes tenía un patrón obstructivo en la espirometría.La comparación entre los tres grupos mostró diferencias estadísticamente significativas en los valores de R5-19, Reactancia a 5 Hz y Reactancia a 11 Hz. No se observaron diferencias entre los tres grupos en Delta Xrs. El estudio mostró una fuerte correlación entre la reactancia total e inspiratoria a 5 Hz y la capacidad vital forzada y capacidad de difusión del monóxido de carbono. Conclusiones: Nuestros resultados sugieren que los hallazgos en EPID son característicos de esta enfermedad y que difieren de los que se encuentran en otras enfermedades como la enfermedad pulmonar obstructiva crónica. También parece que existen diferencias según el grado de deterioro funcional de los pacientes. Los resultados muestran una fuerte correlación con las pruebas estándar de función pulmonar, por lo que la oscilometría podría ser una herramienta útil en pacientes con EPID que no pueden realizarla, y podría aportar información adicional.

Este artigo questiona a apropriação do corpo biológico como objeto científico e padrão de inteligibilidade para as diversas experiências corpóreas dos sujeitos. Por meio de pesquisa genealógica, o estudo do qual este texto derivou analisou textos dos séculos xviii e xix para compreender como o corpo orgânico foi produzido cientificamente, sobretudo pela Fisiologia e pela Anatomia. Destacam-se os embates científicos, políticos, econômicos e sociais que, apagados da história linearizada da ciência, surgem como componentes importantes para que diversos corpos considerados abjetos tenham possibilidade de futuro. São também apresentadas duas discussões atuais (o caso da covid-19 e do TDAH), que, agregando conhecimentos não biológicos (das áreas da Ciências Humanas), trazem possibilidades de rompimento com a biologização dos corpos e de suas experiências.

A educação superior requer inovações e um esforço dos docentes responsáveis pelas disciplinas para que os novos conhecimentos sejam acessíveis aos graduandos, para que consigam produzir múltiplos sentidos aos temas trabalhados. A interdisciplinaridade é também fundamental nesse contexto e sua correspondência na Educação Básica, já que tradicionalmente há uma divisão entre as ciências e os conhecimentos produzidos. Assim, este trabalho, a partir dos pressupostos qualitativos, apresenta uma investigação baseada em experiência pedagógica e tem como objetivos: (i) viabilizar aos futuros professores de Educação Física de uma instituição pública do sul do Brasil, o acesso ao conhecimento interdisciplinar no ensino do conteúdo bioenergética, e (ii) analisar a experiência realizada. A experiência pedagógica é guiada pelas diferentes linguagens relacionadas à arte e ao corpo, resultando na produção de planos de ensino voltados ao Ensino Fundamental da Educação Básica. Como resultados, verificamos que a busca pelo conhecimento interdisciplinar, aliada à mobilização das emoções, é uma abordagem pedagógica poderosa que não apenas enriquece a jornada de aprendizado dos estudantes, mas também, capacita-os a responder às demandas da vida contemporânea a partir de um horizonte teórico ampliado e potencializado holisticamente. Tal abordagem é um investimento valioso no desenvolvimento de futuros professores que serão agentes de transformação na sociedade e terão expertise para mediar conhecimentos relacionados ao corpo e às manifestações corporais.

In the world, there are thousands of people who live in high-altitude cities. These generate a reduction in atmospheric oxygen pressure and hypobaric hypoxia, causing multiple changes in physiological systems. The effect of altitude on pulmonary, cardiac, and hematological function has been extensively studied during acute or chronic exposure, causing increased pulmonary ventilation, arterial pressure variability, and polycythemia. In kidney, it causes a decrease in the glomerular filtration rate, which can trigger chronic kidney disease. Similarly, there are changes in the endocrinological-reproductive axis, in brain and even gastrointestinal function. The maladaptation of these systems generates pathologies such as acute and chronic mountain sickness, pulmonary edema, and high-altitude cerebral edema. This review presents a description of the main changes seen in physiological systems after exposure to altitude. [ABSTRACT FROM AUTHOR]

Introduction and objective: Using videos as complementary teaching material can replace part of the teaching hours and be helpful in acquisition of knowledge in Otorhinolaryngology. To evaluate this alternative the impact of visualizations of 4 videos on performance in specific questions of the Otorhinolaryngology exam will be analyzed and students’ perception of these videos will be evaluated. Method: Quasi-experimental analytical study, conducted in 213 students of Otolaryngology of Autonomous University of Madrid divided in two groups (intervention and control). Differences between intervention and control group were analyzed using the chi-square test or the exact Fisher test (p value<0.05 statistically significant). Feedback from students on the videos was collected. Results: The total number of video visualizations was 883. Significant differences were observed (p < 0.01) on performance in question "ear 1" with 27.78% of success rate of the experimental group versus 7.50% of the control group, and in question "neck 2" with 38.89% of success rate of the experimental group compared to 81.80% of the control group. Most opinions about the videos (94.87%) were positive. Discussion and conclusions: No significant impact on performance was found, easy access to videos and positive feedback from students highlight its usefulness as a complementary teaching material to classes in Otorhinolaryngology.

Physiological changes are responsible for the appearance of aesthetic dysfunctions in the maternal body, among which the following stand out: the appearance of stretch marks, geloid fibroedema, fluid retention, varicose veins, acne and melasma. The skin is mainly affected due to hormonal instability, resulting in the development of changes that are characteristic of the gestational period. The objective of this research was to review the main dermatofunctional physiotherapeutic interventions used in aesthetic dysfunctions acquired during pregnancy. This is an integrative review of the literature. The electronic databases used to carry out the work: PubMed and Google Scholar between the years 2018 and 2023. In the results, 28 articles were selected due to the relevance of which aesthetic dysfunctions occur with greater prevalence during pregnancy and which treatments could be used in physiotherapeutic care. It can be concluded from the study carried out that prevention is the main objective for aesthetic dysfunctions acquired during pregnancy. [ABSTRACT FROM AUTHOR]

Objective. The main idea of this study was to quantify the relationship between climatic variables and tympanic body temperature recorded through the use of wireless sensors in grazing cows located in low tropic. Material and methods. The tympanic temperature of twenty-eight cross breed grazing cows in early lactation was monitored. The sensors were manually installed in the tympanic cavity, recording hourly for 17 days. The climate data was obtained from the network of weather stations of the Centro de Investigación de la Caña de Azúcar "Cenicaña", which is a research center for sugarcane located in Cali, Colombia, this data was analyzed for the same time interval of the temperature. The information was analyzed using descriptive statistics, correlation matrices and Random Forest models, through the R software. Results. From the physiological data from automatic collection systems, the response variables that would allow the evaluation of thermoregulation processes were analyzed using big data. We find that the variables environmental temperature, relative humidity and, solar radiation were the factors that most influenced the homeothermic adaptation process of the animals. Conclusions. The introduction of remote devices, and the use of a large amount of data for the analysis of physiological indicators, avoid modifying natural animal behavior and emerges as an important diagnostic and management strategy in the livestock farm, helping in the studies of heat stress, physiological adaptation and, prevalence to hemotropic diseases, which reduce the productivity of the systems.

Avian anesthesia is a controversial area of study due to the differences between birds and mammals morpho physiology. This makes necessary to develop reliable protocols for birds in captivity, which contributes to their welfare under human care. Bird anesthesiology today represents a veterinary clinical activity that demands special care for patients requiring surgical procedures. This study describes the parameters of SpO2, cardiac activity, heart and respiratory rate during anesthesia with isoflurane for Melopsittacus undulatus. 12 males and 7 females were monitored during the anesthetic stages. Anesthetic induction lasted 1:30 ± 0:31 min in males and 2:19 ± 0:16 min in females, with an average maintenance time of 7:00 ± 1:39 min. No significant differences were found in anesthetic times between females and males (p>0.05). There was a statistically significant variation (p<0.05) of SpO2 in the recovery period, females had higher oxygen saturation (71±4%) compared to males (89±2%). In the assessment of cardiac function during anesthesia, no significant differences were detected between males and females (p>0.05). It is concluded as a safe anesthetic protocol for clinical procedures of short duration for small birds such as M. undulates. [ABSTRACT FROM AUTHOR]

Ethylene-responsive element binding factors (ERFs) are widely involved in the regulation of plant responses to different abiotic stresses. In petunia (Petunia Ã--hybrida), PhERF2 belonging to the subfamily â...? of ERF transcription factors participates in the response to waterlogging stress. In this study, we investigated waterlogging tolerance variation of WT and transgenic petunia plants with RNAi silencing and overexpression of PhERF2 through photosynthetic and physiological performance. Chlorophyll content and root vigor declined continuously in both WT and PhERF2 transgenic lines under waterlogging stress, but the extent of the fall in PhERF2-overexpressing lines was less than that in WT and PhERF2-RNAi lines. At the end of waterlogging treatment, soluble protein levels in PhERF2-overexpressing lines were significantly higher than those in WT and PhERF2-RNAi lines, while the latter showed a higher malondialdehyde content overall. Different degrees of reductions in Pn, Gs, and Tr levels occurred in both WT and PhERF2 transgenic lines upon exposure to waterlogging. The Ci levels of PhERF2-overexpressing lines decreased after 3 hours of waterlogging treatment, and the Ci levels of WT and PhERF2-RNAi lines gradually increased from 6 to 72 hours of waterlogging treatment. These data suggested that non-stomatal factors were the primary limiting factors for Pn in WT and PhERF2-RNAi lines under severe stress, while the stomatal opening was the main factor limiting Pn in PhERF2-overexpressing lines. Our results demonstrated that the contribution of PhERF2 to the waterlogging tolerance of petunia appears to depend on the regulation of physiological and photosynthetic responses. PhERF2 represents a hopeful candidate gene for enhancing waterlogging tolerance of ornamental plants. [ABSTRACT FROM AUTHOR]

A prática esportiva por adolescentes tem aumentado nos últimos anos, inclusive nesta direção, tem-se observado um crescente processo de profissionalização do esporte. O processo sistemático e rigoroso de treinamento exigido no esporte de alto rendimento, segundo alguns estudos, promove alterações na morfologia do ventrículo esquerdo em atletas adolescentes. O objetivo foi revisar na literatura sobre a influência do treinamento esportivo na adaptação do ventrículo esquerdo de jovens atletas. Este trabalho tem como delineamento a revisão narrativa, sendo consultadas bases eletrônicas de bibliotecas virtuais (Pubmed e Scielo). Dos 230 artigos encontrados,14 foram incluídos nessa revisão. O resultado da análise dos artigos verificou-se que o treinamento promove alterações sobre ventrículo esquerdo, nas quais são observadas aumento das dimensões cavitarias, massa ventricular esquerda total e massa indexada pela superfície corpórea, além da espessura relativa da parede maior em atletas, principalmente no sexo masculino e em negros quando comparados a mulheres e brancos esportistas e ao grupo de sedentários, sem diferença significativa na fração de ejeção entre os diversos grupos estudados. Concluímos que o treinamento físico regular e intensivo está associado a diversas adaptações estruturais que resultam na hipertrofia do ventrículo esquerdo em jovens atletas. A magnitude dessas adaptações é determinada por diversos fatores incluindo idade, sexo, tamanho do corpo, etnia, tipo e intensidade do exercício praticado. No entanto, a maioria dos estudos encontrados tem delineamento transversal, sugerindo assim novos estudos com abordagem longitudinal.

A composição corporal é atualmente um dos aspectos mais importantes do futebol, haja vista que é necessário ter bons índices musculares, ósseos e de gordura para executar as ações motoras exigidas pelo esporte. No entanto, o quanto a constituição corpórea está relacionada com variáveis como a potência muscular? Com a intenção de responder essa pergunta o objetivo do presente estudo foi investigar as relações entre a composição corporal total e fracionada e a potência muscular de jovens futebolistas. Para isso, 27 atletas participaram da presente pesquisa, os quais foram separados em dois grupos sendo, grupo 1 (G1) da categoria sub 15 com 13 jogadores (13,1 ± 01anos; 53,46 ± 3,1kg; 164 ± 2,5cm) e grupo 2 (G2) pertencente a categoria sub 20 com 14 atletas (18,3 ± 03anos; 71,83 ± 1,8kg; 177 ± 1,6cm). Os participantes realizaram avaliação antropométrica e da composição corporal com o DEXA e executaram o Running Based Anaerobic Sprint Test (RAST). Como resultado, o G1 apontou os maiores coeficientes de correlação, como, por exemplo, 0,952 na relação entre MMT x PPA e de 0,900 para MMMI (p

El objetivo de este estudio fue verificar los parámetros fisiológicos, hematológicos y bioquímicos séricos de caballos atletas sometidos al deporte de lazo en el Estado de Mato Grosso do Sul, Brasil. Con ese propósito fueron evaluados seis machos y dos hembras en dos momentos diferentes, antes y después de la prueba, caracterizados como M0 y M1. En relación con los parámetros fisiológicos, referentes a la temperatura rectal, frecuencia cardíaca y frecuencia respiratoria, el resultado en el M0 fue de (37,23±0,25, 42,75±6,22 e 29,75±8,77), respectivamente, en cuanto en el M1 (37,97±0,34, 64,35±13,34, 60,87±11,28), inmediatamente de realizada la prueba del deporte del lazo se observó un aumento en estos parámetros. En los valores hematológicos fue observada solo una alteración del VCM después del ejercicio, esto ocurre debido al aumento de eritrocitos. En relación con los parámetros bioquímicos séricos, ocurrió aumento en M1 la medición de la enzima aspartato aminotransferasa (AST) y reducción de los niveles de glucosa sanguínea. Podemos concluir que ocurrieron alteraciones fisiológicas, hematológicas y bioquímicas séricas inmediatamente después a la realización de la prueba en caballos atletas, debido a necesidades fisiológicas del ejercicio equino. Las mayores alteraciones fueron observadas en los resultados fisiológicos del VCM, AST, LDH, CK y glucosa sanguínea de los caballos sometidos a la prueba del deporte de lazo en este trabajo.

Pocos años después de la declaración de independencia en 1821, salieron de las imprentas peruanas las primeras obras de filosofía del periodo republicano. A través de un trabajo de archivo, podemos concluir que la primera obra filosófica en el Perú independiente es el Nuevo mundo filosófico (1823) del médico y matemático arequipeño Juan de Dios Salazar, aunque una versión más breve y parcial de esta se publicó un año antes con el título de Discurso ideológico (1822). El análisis de ese escrito deja ver una gnoseología de corte sensualista que se entremezcla con elementos propios de las fisiologías de su tiempo. Nuestra investigación esclarece una etapa de la historia de las ideas y de la medicina en el país que hasta ahora ha sido apenas estudiada, y pretende proporcionar al lector un primer acercamiento a la implantación de corrientes como el sensualismo, la ideología o el vitalismo médico en el Perú.

This is a case series about retinal arterial macroaneurysms in three patients recovered from COVID-19. None of them had previous past ocular and systemic history. The first patient was a 47-year-old man, with best-corrected visual acuity of 20/20 in both eyes. He presented a cotton wool spot in the right eye and two peripheral exudative retinal arterial macroaneurysms in the left eye. Laser photocoagulation was performed and best-corrected visual acuity remained stable. The second one was a 62-year-old- woman with acute visual loss in the right eye (best-corrected visual acuity of 20/400). There was vitreous hemorrhage and a peripheral retinal arterial macroaneurysm in the right eye. Laser photocoagulation was performed and best-corrected visual acuity improved to 20/20. The third patient was a 54-year- old woman, with best-corrected visual acuity of 20/20 in the right eye and 20/600 in the left eye. Fundus examination showed multiple layer hemorrhage in the macular region and retinal arterial macroaneurysms in the superior temporal branch. The cases underwent fluorescein angiography, which confirmed the diagnosis of retinal arterial macroaneurysms. [ABSTRACT FROM AUTHOR]

The research was carried out under semi-controlled conditions from November to February of the years 2016, 2017 and 2018 in the Scientific Technological Unit of Base Los Palacios, Cuba, with the aim of evaluating the effect of the water deficit on the physiological efficiency of the bean (Phaseolus vulgaris L.) cv. "Delicia 364". 80 bean seeds were sown per 1.40 m² pot. A Completely Randomized Experimental Design was used, with three treatments and four repetitions: two with water deficit (beginning of wilting of the leaves and when the yellowing of the apex of the leaves began) and a control with irrigation at field capacity. The water deficit was applied when the plants had between three and four true leaves. After each period of stress, the foliar water potential was determined and at the time of harvest the dry mass, the agricultural yield and its components. It was found that the water deficit imposed in the vegetative phase at different intensities caused a state of water stress in the bean plant and after recovering from it, caused increases in the aerial dry mass, number of pods and agricultural yield. The water deficit in bean plants until the beginning of the yellowing of the apex of the leaves, during the vegetative phase, increases the physiological efficiency of the plant depending on irrigation, between 16-25 %, in terms of the aerial dry mass, the number of pods per plant and the agricultural yield.
