Mamali, P.; Samartzi, F.; Batzias, G. C.; Theodosiadou, E.; Vainas, E.; Goulas, P.; Belibasaki, S.; Saratsis, F. (2008) -
Effect of eCG on Steroid Hormone Concentrations and Plasminogen Activator Activity in the Genital Tract of Ewes
Samartzi, F.; Theodosiadou, E.; Tsiligianni, T.; Lymberopoulos, A. G.; Vainas, E.; Rekkas, C. A. (2009) -
Effect of eCG on the Activity of Glucosidases in the Genital Tract of Ewes
Samartzi, F.; Tsiligianni, T.; Theodosiadou, E.; Lymberopoulos, A. G.; Vainas, E.; Rekkas, C. A. (2009) -
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 ... -
Effect of porcine and ovine FSH on nuclear maturation of pig oocytes in vitro
Samartzi, F.; Tsakmakidis, I.; Theodosiado, E.; Vainas, E. (2008)The effect of porcine or ovine FSH on the maturation rate of porcine oocytes and on the time course of meiotic progression was studied. Groups of 20 grade-A cumulus oocyte complexes, aspirated from slaughterhouse cycling-gilt ... -
The effect of repeated follicular aspiration on the onset of puberty and growth rate of winter- or autumn-born lambs
Valasi, I.; Fthenakis, G. C.; Prassinos, N. N.; Menegatos, I.; Grigoropoulou, V.; Deligiannis, C.; Vainas, E.; Amiridis, G. S. (2009)The effects of follicular aspiration for oocyte retrieval on the attainment of puberty and growth rate were studied in winter-born (9 treated and 6 control) and autumn-born (5 treated and 5 control) ewe lambs. In the treated ... -
Effects of melatonin treatment on follicular development and oocyte quality in Chios ewes - Short communication
Tsiligianni, T.; Valasi, I.; Cseh, S.; Vainas, E.; Faigl, V.; Samartzi, F.; Papanikolaou, T.; Dovolou, E.; Amiridis, G. (2009)Follicular development and oocyte quality were assessed by laparoscopic observation and in vitro fertilisation, respectively, in melatonin-treated (Group M) and control (Group C) anoestrous Chios ewes (n = 10 in each group). ... -
Follicle ablation improves the ovarian response and the number of collected embryos in superovulated cows during the early stages of lactation
Amiridis, G. S.; Tsiligianni, T.; Vainas, E. (2006)A field study was designed to compare ovarian response and embryo yield in cows during early lactation when gonadotropin administration followed one of four treatments. In group 1A (n = 19) and 1B (n = 9), the estrouses ... -
In Vitro Effect of alpha-Zearalenol on the Porcine Preimlantation Conceptus
Saratsi, A.; Theodosiadou, E.; Rekkas, C. A.; Angelopoulou, K.; Vainas, E.; Lymberopoulos, A. G.; Boscos, C. M. (2008) -
Progesterone concentration as an indicator of ovarian response to superovulation in Chios ewes
Amiridis, G. S.; Rekkas, C. A.; Fthenakis, G. C.; Vainas, E.; Lymberopoulos, A.; Christodoulou, V.; Belibasaki, S. (2002)We investigated the prediction of the ovarian response to superovulation using progesterone (P-4) determination in Chios ewes. During the estrus period, estrus synchronization and multiple ovulations were induced in 100 ... -
Relationship between oocyte maturation and the activity of two glycosidases beta-N-acetyloglucosaminidase (NAGASE), alpha-mannosidase (alpha-MAN) in bovine follicular fluid
Tsiligianni, T.; Samartzi, F.; Dovolou, E.; Vainas, E.; Amiridis, G.; Perreau, C.; Mermillod, P. (2012) -
Reproductive efficiency of three estrus synchronization schemes comprising fixed-time insemination in dairy cows
Amiridis, G. S.; Belibasaki, S.; Leontides, L.; Lymberopoulos, A.; Vainas, E. (2000)The objective of this field trial was to compare the odds of pregnancy at 25 days (P25) and at 60 days (P60), of embryonic death (ED) between 25 and 60 days, and of non-pregnant cows returning to heat 20-25 days after ... -
