Effect of resveratrol supplementation in conventional slow and ultra-rapid freezing media on the quality and fertility of bull sperm.

The study investigated the impact of resveratrol (RES) on bull sperm cryopreservation employing conventional slow (CS) and ultra-rapid (UR) freezing methods on sperm quality and in vitro fertility. Twenty-four ejaculates from four bulls were divided into four groups based on the cryopreservation method and RES addition: CS-RES (n = 80), CS-Co (n = 80), UR-RES (n = 24), and UR-Co (n = 24). The CS freezing involved exposing sperm straws with 5% glycerol to liquid nitrogen (LN2) vapors, while UR freezing submerged sperm drops with 100 mM sucrose directly into LN2. Overall, sperm kinematic parameters and integrity of plasma and acrosome membranes significantly decreased (P < 0.001) after cryopreservation. Post-thaw values of motilities (total [TM] and progressive [PSM]), velocities (curvilinear and straight-line), beat cross frequency (BCF), and sperm with intact plasma membrane/intact acrosome (PI-/PNA-) were higher (P < 0.05) with CS-RES and CS-Co treatments compared to UR-RES and UR-Co treatments. CS-RES treatment resulted in greater percentages (P < 0.05) of TM, PSM, PI-/PNA-, and fertility (blastocyst rate) than their control, CS-Co; while UR-RES showed higher BCF values (P < 0.05) than its control, UR-Co. Additionally, UR-RES treatment exhibited lower oxidative stress percentages than UR-Co (P < 0.05). This study presents the following conclusions: (1) the CS freezing resulted in better cryosurvival of bull sperm than UR freezing; (2) the RES supplementation to CS freezing medium improved sperm motility, membrane integrity, and fertility; and (3) despite low cryosurvival sperm and fertility, the RES addition to ultra-rapid freezing medium reduced oxidative stress.

Condiciones de salud asociadas a discapacidad en adultos mayores de un programa de actividad física / Health conditions associated to disability in older adults attending a physical activity program

Introducción: Existe la tendencia mundial del aumento de población adulta mayor. Colombia no es un país ajeno a esta situación. Objetivo: Determinar las condiciones crónicas de salud asociadas al desarrollo de discapacidad en adultos mayores de la ciudad de Santiago de Cali, Colombia. Métodos: Estudio transversal en el que participaron 322 adultos mayores, seleccionados con muestreo aleatorio estratificado proporcional. Se aplicó la Encuesta de Salud, Bienestar y Envejecimiento Colombia, en su sección 8, y el WHODAS 2.0, versión de 36 preguntas. Resultados: El 90,4 por ciento de los participantes en el estudio eran mujeres, la mediana de edad fue de 70 años. La media de discapacidad global fue de 9,39 ± 10,2 puntos. La movilidad obtuvo la mayor puntuación 13,80 ± 17,79 (escala de 0-100 puntos) y las de menor puntuación fueron AVD-trabajo remunerado y participación (2,240 ± 11,15 puntos). La hipertensión arterial fue el padecimiento con mayor prevalencia. Los adultos que han sufrido embolias reportaron el mayor nivel de discapacidad (18,395), seguido de los que manifestaron haber tenido algún tipo de alteración mental (14,15 por ciento ). El dominio con mayor significancia estadística fue la participación, más afectada en los adultos con diabetes, ataques al corazón, embolia cerebral, artritis, osteoporosis y cataratas. Conclusiones: Hubo presencia de enfermedades crónicas en los sistemas cardiovascular, pulmonar y músculo-esquelético, aunque se reportaron niveles bajos discapacidad. Las actividades de la vida diaria más complejas son las que primero presentan dificultad; además, la movilidad es crucial para el funcionamiento de los adultos mayores(AU)

Introduction: Increase in the number of older adults is a current worldwide tendency. Colombia is not an exception. Objective: Determine the chronic health conditions associated to the development of disability in older adults from the city of Santiago de Cali, Colombia. Methods: A cross-sectional study was conducted of 322 older adults selected by proportional stratified random sampling. Data were obtained with the survey Health, Wellbeing and Aging Colombia, section 8, and the tool WHODAS 2.0, 36-item version. Results: Of the participants in the study, 90.4 percent were women; mean age was 70 years. Mean global disability was 9.39 ± 10.2 points. Mobility obtained the highest score (13.80 ± 17.79 on a 0-100 scale), whereas the lowest ranking variables were ADL - paid work and participation (2.240 ± 11.15 points). Arterial hypertension was the most common condition. Patients who had had embolisms reported the highest level of disability (18.395), followed by those reporting having had some sort of mental disorder (14.15 percent). The domain with the greatest statistical significance was participation, which was more affected in adults with diabetes, heart attacks, cerebral embolism, arthritis, osteoporosis and cataract. Conclusions: A presence was observed of chronic diseases of the cardiovascular, respiratory and musculoskeletal systems, though low disability levels were reported. The most complex activities of daily living are the first to present difficulty. On the other hand, mobility is crucial for the functioning of older adults(AU)

Terapia familiar sistémica en contextos de pobreza / Systemic family therapy in contexts of poverty

Sin duda alguna, un par de páginas se han de quedar cortas a la hora de desglosar un poco sobre aquellos enfoques direccionados hacia el ser humano, desde lo individual, hasta su interacción en grupo y sociedad. Aun así, el presente artículo permite dar una mirada estructural y básica de lo que conlleva a la mención del concepto de Terapia Familiar Sistémica, en éste caso desarrollada en contextos de pobreza, básicamente en América Latina, y más específicamente en Colombia. A través de una contextualización estructurada de términos, ubicados en la raíz del tema principal, se pretende hacer un recorrido que vaya desde lo más sencillo, hasta lo más elaborado, para finalmente impregnar al lector, de una forma más clara y globalizada, de la ubicación y el universo que se constituye alrededor de la Terapia Familiar Sistémica, en los contextos de pobreza; su constitución, fundamento e importancia en nuestra sociedad.

Anyway a couple of pages will be short when we want to drill down a bit on those directed towards the human being approaches from the individual to his group interaction and society. Even so, this article can give a structural and basic look of what it takes to mention the concept of Systemic Family Therapy, developed in contexts of poverty, mainly in Latin America and more specifically in Colombia. Through a structured contextualization of terms, located in the root of the main theme it is to make a journey that goes from the simplest to the most elaborated, and finally imbue the reader of a clearer and globalized form of the location and the universe that is around the Systemic Family Therapy in contexts of poverty; its constitution, foundation and importance in our society.
