RESUMEN
El estudio pretende conocer la visión de enfermeros líderes sobre el liderazgo. Estudio cualitativo, descriptivo, realizado con 12 enfermeros que ocupan cargos de liderazgo en instituciones ubicadas en Montes Claros, Minas Gerais, Brasil. Los datos fueron recogidos a través de entrevista no estructurada y sometidos a análisis de contenido. Los resultados mostraron que los encuestados tienen una visión clara del tema y su importancia para la profesión. Entienden el liderazgo como un proceso que influye sobre las personas o comportamientos, buscando metas, además de considerarla una habilidad que puede aprenderse. Son conscientes de la estrecha relación entre liderazgo y enfermería y reconocen la dificultad de ejercerla en el equipo, que se convierte en específica dependiendo del área de actuación(AU)

The present study was undertaken to investigate the presence of angiotensin-(1-7) [Ang-(1-7)] in the ovary and a possible role for it. Cycling female rats were killed in each phase of the estrous cycle, and ovarian Ang II and Ang-(1-7) were separated by HPLC and measured by RIA. The mean levels of Ang-(1-7) in proestrus and estrus were significantly higher than those in metestrus and diestrus (P < 0.05). Ang-(1-7) was also significantly higher in equine chorionic gonadotropin (eCG)-treated immature rats. Ang-(1-7) induced a significant increase in estradiol and progesterone production (P < 0.05) in the ovary of immature rats (24-25 d old) pretreated with eCG and perfused in a closed circuit system. This effect was blocked by A-779, a specific Ang-(1-7) antagonist (P < 0.05). The present data demonstrate the presence and physiological role of a novel renin-Ang system peptide in the ovary. The higher level of Ang-(1-7) in proestrus and estrus as well as in eCG-treated rats suggests the involvement of this renin-Ang system peptide in pre- and postovulatory events.
