Age, FSH dose and follicular aspiration frequency affect oocyte yield from juvenile donor lambs
Valasi, I.; Leontides, L.; Papanikolaou, T.; Amiridis, G. S. (2007)Experiments were conducted to determine the effects of lamb age, frequency of follicular aspirations, and hormone stimulation by fixed or variable FSH dose, on the number of collected oocytes and their maturational competence. ... -
Effect of plasmin, plasminogen activators and a plasmin inhibitor on bovine in vitro embryo production
Papanikolaou, T.; Amiridis, G. S.; Dimitriadis, I.; Vainas, E.; Rekkas, C. A. (2008)In the present study, four experiments were conducted to investigate the possible effects of plasminogen activators (urokinase-type plasminogen activator (u-PA) and tissue-type plasminogen activator (t-PA)), plasmin, and ... -

Factors affecting chromatin stability of bovine spermatozoa
Khalifa, T. A. A.; Rekkas, C. A.; Lymberopoulos, A. G.; Sioga, A.; Dimitriadis, I.; Papanikolaou, T. (2008)The structural stability of transcriptionally inert paternal chromatin is of vital importance for the fertilization process and early embryonic development. Accordingly, a series of eight experiments were conducted during ... -

Amiridis, G. S.; Valasi, I.; Menegatos, I.; Rekkas, C.; Goulas, P.; Papanikolaou, T.; Deligiannis, C. (2005)Possible hormonal aberrations precluding conception or maintenance of pregnancy in dairy ewes subjected to ovulation synchronisation were investigated in this study. The pituitary response to exogenous gonadotrophin-releasing ... -
