Experimentally induced orchitis associated with Arcanobacterium pyogenes: clinical, ultrasonographic, seminological and pathological features
Gouletsou, P. G.; Fthenakis, G. C.; Cripps, P. J.; Papaioannou, N.; Lainas, T.; Psalla, D.; Amiridis, G. S. (2004)The objectives of this study were to describe the features of experimentally induced orchitis associated with Arcanobacterium pyogenes and confirm the pathogenicity of the organism for the ovine testicle. One testicle of ... -
Flunixin meglumine accelerates uterine involution and shortens the calving-to-first-oestrus interval in cows with puerperal metritis
Amiridis, G. S.; Leontides, L.; Tassos, E.; Kostoulas, P.; Fthenakis, G. C. (2001) -
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 ... -
Follicular Development after Repeated Ovum Pick-up (OPU) in Cyclic Ewes
Valasi, I.; Papanikolaou, T. H.; Tsiligianni, T. H.; Theodosiadou, E.; Kantas, D.; Deligiannis, C.; Amiridis, G. S. (2008) -
Formation of a secondary corpus luteum after ultrasound-guided follicular aspiration in cows
Amiridis, G. S.; Robertson, L.; Jeffcoate, I. A.; Belibasaki, S.; Boyd, J. S.; O'Shaughnessy, P. J. (2000)This paper reports the observed formation of a secondary corpus luteum (CL) in the presence of the cyclic corpus luteum, on the ovaries of a cow after ultrasound-guided follicular aspiration for oocyte recovery. The secondary ... -
Ghrelin accelerates in vitro maturation of bovine oocytes
Amiridis, G. S.; Dovolou, E.; Messinis, I.; Guttierez-Adan, A.; Periquesta, E.; Dafopoulos, K. (2014) -
Ghrelin decreases pituitary response to GnRH in superovulated ewes
Dovolou, E.; Chadio, S.; Messinis, I. E.; Rekkas, C.; Deligiannis, C.; Kalogiannis, D.; Amiridis, G. S. (2013) -
Human ghrelin decreases pituitary response to GnRH in superovulated ewes
Dovolou, E.; Chadio, S.; Messinis, I. E.; Rekkas, C. A.; Deligiannis, C.; Kalogiannis, D.; Amiridis, G. S. (2013)In addition to its metabolic role, ghrelin has been found to suppress luteinizing hormone secretion in many species acting mainly at the hypothalamic level. The objectives of the present study were to test the hypothesis ... -
Incidence risk and clinical features of retention of foetal membranes in ewes in 28 flocks in southern Greece
Fthenakis, G. C.; Leontides, L. S.; Amiridis, G. S.; Saratsis, P. (2000)In a field investigation of 28 flocks in southern Greece, 7660 lambings were monitored. Retention of foetal membranes (defined as failure to expel the foetal membranes within 6 h of lambing the last lamb) was recorded in ... -
Luteal stage dependence of pituitary response to gonadotrophin-releasing hormone in cyclic dairy ewes subjected to synchronisation of ovulation
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 ... -
Management of pre-pubertal small ruminants: Physiological basis and clinical approach
Valasi, I.; Chadio, S.; Fthenakis, G. C.; Amiridis, G. S. (2012)Puberty is a gradual process, during which animal reproductive competence is attained with respect to physiology, morphology and behaviour. Onset of puberty in small ruminants differs between sexes, due to early sexual ... -
A matched case-control study of factors associated with retention of fetal membranes in dairy ewes in Southern Greece
Leontides, L.; Fthenakis, G. C.; Amiridis, G. S.; Saratsis, P. (2000)We defined retention of fetal membranes (RFM) in dairy ewes as failure to expel the placenta within 6 h after lambing the last lamb and designed a matched case-control study to identify factors that affect the risk of ... -
Oestradiol concentration as a predictor of ovarian response in FSH stimulated ewe-lambs
Valasi, I.; Leontides, L.; Menegatos, I.; Amiridis, G. S. (2007)We investigated the prediction of ovarian response using oestradiol determination, in 37 gonadotrophin stimulated Karagouniko ewe-lambs. Ovarian stimulation was induced by serial FSH administrations, and laparoscopic ... -
Oocyte pick-up in juvenile lambs affects neither onset of puberty nor their future fertility
Valasi, I.; Menegatos, I.; Papanikolaou, Th; Goulas, P.; Amiridis, G. S. (2006)A study was designed to evaluate whether the time of onset of puberty and fertility of young ewe lambs would be affected by oocyte pick-up conducted in single or repeated sessions during the first months of lambs' live. ... -
