Avaliação uterina e ovariana de éguas por meio da ultrassonografia Doppler

Doppler ultrasonography is a new technology that has been study by researchers to improve the physiologic and pathologic knowledge about reproduction. This technology is based on Doppler-shifts frequencies or ultrasonic, these frequencies can be increase or decrease according to the movements of the red cells in the vessel. Color Doppler and power Doppler are the two possibilities to use the Doppler ultrasonography. Color Doppler is based in more the one color that show the direction of the blood f low and power Doppler is based in one color that change according of the flow intensity. Doppler ultrasonography can be demonstrated with the spectral mode to verify blood flow in large vessels, because of this, it is not use in equine reproduction. Studies in equine reproduction have been doing to verify uterus blood flow in cyclic mares and to observe the vascular perfusion in mares with cists, uterine vascular perfusion post breeding and verify the affects of drugs to decrease the uterus fluid in mares with problems in uterus perfusion. The ovarian irrigation during the estrus cycle was analyze with the measurement of the principal hormones during the estrus cycle in mares, the integrity of the corpus luteus, the irrigation of the future dominant follicle and the consequences in the ovarian irrigation after luteolyse induction also were study. Nevertheless, more than the knowledge that existed about Doppler ultrasonography, new studies have been doing to improve the forms to use Doppler ultrasonography in equine reproduction

Influência do exercício resistido com restrição do fluxo sanguíneo sobre ativação muscular

Conventional resistance training (TRC) is capable to generate muscular responses according to provided stimuli, as, training volume and intensity. The TRC results in force gains in general. Studies aim this gain to neural adaptation initially, followed by hypertrophy gains. However, studies that used TRC associated to blood flow restriction (RFS) found rise in force and hypertrophy without necessarily detecting rise in neural activity. Therefore this review had as objective, bring up literature data that report this fact and yet, speculate possible elucidation about this responses inversion
