Since the discovery of ischemic pre- and post-conditioning, more than 30 years ago, the knowledge about the
mechanisms and signaling pathways involved in these processes has significantly increased. In clinical practice, on the other
hand, such advancement has yet to be seen. This article provides an overview of ischemic pre-, post-, remote, and
pharmacological conditioning related to the heart. In addition, we reviewed the cardioprotective signaling pathways and
therapeutic agents involved in the above-mentioned processes, aiming to provide a comprehensive evaluation of the
advancements in the field. The advancements made over the last decades cannot be ignored and with the exponential growth
in techniques and applications. The future of pre- and post-conditioning is promising.
Objetivou-se avaliar o efeito da suplementação de vitamina E na morfometria e no desenvolvimento gonadal de tilápia (Oreochromis niloticus). Para peso da gônada, índice gonadossomático (IGS), espessura do testículo e porcentagem de lúmen foram observadas diferenças para tratamento 150 mg/kg de vitamina E. Para epitélio germinativo foi observada diferença para o tratamento com 150 mg e para porcentagem de células de Leydig do tratamento com 50 mg de vitamina E por kg. Para vasos sanguíneos foi maior com 50 e 150 mg. A exigência de vitamina E para desenvolvimento gonadal da tilápia é de 150 mg/kg.
