Effects of Addition of Tissue-Type Plasminogen Activator in In Vitro Fertilization Medium on Bovine Embryo Development and Quality

Krania, F.; Dovolou, E.; Rekkas, C. A.; Theodosiadou, E. K.; Pappas, I.; Amiridis, G. S. (2015)

Contents Plasminogen activators/Plasmin system plays pivotal role in regulating reproductive functions of mammals. Here, we examined the effects of modification of in vitro fertilization medium (IVF medium) with the addition ...
Induction of the acrosome reaction in bull spermatozoa with plasmin

Taitzoglou, I. A.; Chapman, D. A.; Killian, G. J. (2003)

Proteolytic enzymes appear to have an essential role in multiple phases of mammalian fertilization. Plasmin, the active enzyme of the plasminogen activation system that stimulates fibrinolysis and proteolysis has a less ...
Inhibition of human and ovine acrosomal enzymes by tannic acid in vitro

Taitzoglou, I. A.; Tsantarliotou, M.; Zervos, I.; Kouretas, D.; Kokolis, N. A. (2001)

The effect of tannic acid, a common flavonoid, on the acrosin and plasminogen activator activity and plasmin activity of human and ram spermatozoa was evaluated. Acrosin and plasminogen activator activity were determined ...
