Association between physical properties of cervical mucus and ovulation rate in superovulated cows
Tsiligianni, T.; Amiridis, G. S.; Dovolou, E.; Menegatos, I.; Chadio, S.; Rizos, D.; Gutierrez-Adan, A. (2011)Possible associations between certain physical properties of cervical mucus (CM) and ovulation rate were studied in 21 superovulated Holstein cows. In CM samples collected at the beginning of estrus (0 h) and in 4 h intervals ... -
Combined administration of gonadotropin-releasing hormone, progesterone, and meloxicam is an effective treatment for the repeat-breeder cow
Amiridis, G. S.; Tsiligianni, T.; Dovolou, E.; Rekkas, C.; Vouzaras, D.; Menegatos, I. (2009)In practice, the etiologic treatment of the repeat-breeder cow is nearly infeasible. In this study, we tested the hypothesis that a combined treatment would benefit the conception rate of repeat-breeder cows. The components ... -
Daily supplementation with ghrelin improves in vitro bovine blastocysts formation rate and alters gene expression related to embryo quality
Dovolou, E.; Periquesta, E.; Messinis, I. E.; Tsiligianni, T.; Dafopoulos, K.; Gutierrez-Adan, A.; Amiridis, G. S. (2014)Ghrelin is a gastric peptide having regulatory role in the reproductive system functionality, acting mainly at central level. Because the expression of ghrelin system (ghrelin and its receptor) has been detected in the ... -
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 ... -
Effects of Guaiazulene on In Vitro Bovine Embryo Production and on mRNA Transcripts Related to Embryo Quality
Dovolou, E.; Clemente, M.; Amiridis, G. S.; Messinis, I.; Kallitsaris, A.; Gutierrez-Adan, A.; Rizos, D. (2011)Contents: Reactive oxygen species (ROS) are between the major contributors for the reduced rate of in vitro bovine embryo production. It is believed that they can cause abnormal meiosis of oocytes, developmental arrest or ... -
EFFECTS OF GUAIAZULENE ON IN VITRO CULTURE OF BOVINE ZYGOTES, AND ON mRNA TRANSCRIPTS RELATED TO EMBRYO QUALITY
Dovolou, E.; Clemente, M.; Amiridis, G. S.; Messinis, I.; Kalitsaris, A.; Gutierrez-Adan, A.; Rizos, D. (2009) -
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). ... -
Efficacy of feeding cow colostrum to newborn lambs
Tsiligianni, T.; Dovolou, E.; Amiridis, G. S. (2012)In the present study the efficacy of feeding cow colostrum to newborn lambs was investigated. Seventy two newborn lambs were divided into 6 groups and were fed as follows: groups 1 to 3 received 4 meals of 1st or 2nd or ... -
Ghrelin accelerates in vitro maturation of bovine oocytes

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 ... -
Prevalence of Coxiella burnetii antibodies in bulk milk and blood serum and associations with reproductive indices in cow dairy herds of Central and Northern Greece
Dovolou, E.; Tsiligianni, T.; Vouzaras, D.; Amiridis, G. S. (2011)For the first time in Greece, we investigated the prevalence of Coxiella burnetii antibodies in milk and sera from dairy cattle herds located at central and northern parts of the country. Eighty herds were initially voluntary ... -
