Este trabajo articula aspectos de la construcción de conocimiento en embriología humana, a partir de una etnografía en laboratorios de reproducción asistida realizado en la ciudad y provincia de Buenos Aires. Médicos y embriólogos conformaron los sujetos de estudio de esta investigación que focaliza en la construcción material y simbólica de embriones. Ambas profesiones involucran experiencias divergentes que serán analizadas y recuperadas a partir del punto de vista de los actores. Con trayectorias profesionales heterogéneas, los relatos profesionales en torno al 'inicio' en la FIV (Fertilización in Vitro) se organizan, para los embriólogos en torno a diferencias entre la 'ciencia' y el 'trabajo'. Los embriólogos proceden en su mayor parte de la investigación en ciencias básicas, con mayor o menor inserción en los organismos públicos (Conicet y Universidad en su mayor parte), de tal forma que la 'vida anterior' de un embriólogo puede tener poco que ver con el ámbito de la salud e incluso con los humanos. Mientras tanto, los médicos encuentran en el espacio de la actividad una continuidad con las prácticas 'aprendidas' en el ejercicio de la profesión. Esta disparidad de experiencias, da cuenta de la ausencia de espacios formales de especialización o entrenamiento profesional en embriología y de las prácticas de standarización formal y jerárquica de la intervención en biomedicina. Las tensiones que atraviesan las relaciones al interior de estos equipos revelan aspectos no resueltos de los procesos de estabilización tecnológica imprescindibles para el ejercicio profesional

Objective: analyze the effect of Kinesio Taping (KT) on the indirect clinical markers of muscle damage induced by eccentric exercises in the elbow flexors in healthy individuals. Materials and methods: It is a randomized controlled trial involving sixty volunteers at age group between 18 and 28 years randomly selected. The sample into three groups with twenty participants: control group (CG) – eccentric protocol without KT, KT group – eccentric with tensioned KT, placebo group – eccentric protocol KT with no tension. The evaluations took place at four moments; the first one was the basis line (AV1), after the second protocol (AV2) and the following two groups 24 (AV3) and 48 hours (AV4) after the intervention protocol. The muscle damage was induced by sixteen maximum eccentric contractions of the elbow flexors from the non-dominant limb, divided in two sets of eight repetitions, at 60º/s, with two minutes interval. The variables analyzed were: the joint amplitude in rest, the level of pain, the joint position sense (JPS) followed of isokinetic checking with electromyographic sign capitation. These data were analyzed in software SPSS 20.0. The normality was identified by Kolmogorov-Smimov examination and then, being used the ANOVA mixed model with significance of 5%. Outcomes: a decrease was observed at joint amplitude moreover, an immediate increase of pain wich increased after 24 and remained until 48 hours at all groups searched. There was not difference at the JPS. The variables peak torque, average peak torque, total work and mean power mean reduced until 48 hours after muscle lesion in all groups. Among the groups, there was no difference in EMG values and for any of the variables. Conclusion: The KT did not influence at the indirect clinical markers of muscle lesion induced by eccentric exercises in the elbow flexors in healthy people.
