Complement: An inflammatory pathway fulfilling multiple roles at the interface of innate immunity and development

Mastellos, D.; Germenis, A. E.; Lambris, J. D. (2005)

Complement has been long perceived as an innate immune system that plays a pivotal role in the maintenance of host defense against infectious agents and the propagation of proinflammatory responses in the context of human ...

Developmental competence of heat stressed oocytes from Holstein and Limousine cows matured in vitro

Stamperna K., Dovolou E., Giannoulis T., Kalemkeridou M., Nanas I., Dadouli K., Moutou K., Mamuris Z., Amiridis G.S. (2021)

The negative effects of heat stress on dairy cattle's fertility have been extensively studied, but the relevant knowledge for beef cattle is rather limited. The aims of this study were to investigate the effects of HS ...

The effects of heat shock protein 70 addition in the culture medium on the development and quality of in vitro produced heat shocked bovine embryos

Stamperna K., Giannoulis T., Dovolou E., Kalemkeridou M., Nanas I., Dadouli K., Moutou K., Mamuris Z., Amiridis G.S. (2021)

The aims of the present study were to examine the effects of HSP70 addition in the in vitro culture medium of day 3 embryos on their developmental competence and quality. Bovine oocytes (n = 1442) were in vitro matured, ...

Genes and conditions controlling mammalian pre-and post-implantation embryo development

Anifandis G., Messini C.I., Dafopoulos K., Messinis I.E. (2015)

Embryo quality during the in vitro developmental period is of great clinical importance. Experimental genetic studies during this period have demonstrated the association between specific gene expression profiles and the ...

Host-associated bacterial succession during the early embryonic stages and first feeding in farmed gilthead sea bream (Sparus aurata)

Nikouli E., Meziti A., Antonopoulou E., Mente E., Kormas K.A. (2019)

One of the most widely reared fish in the Mediterranean Sea is Sparus aurata. The succession of S. aurata whole-body microbiota in fertilized eggs, five, 15, 21 and 71 days post hatch (dph) larvae and the contribution of ...

Leptin in pregnancy

Domali, E.; Messinis, I. E. (2002)

Leptin is a 16-kDa polypeptide, encoded in humans by the LEP gene. This protein is probably involved in the regulation of ovarian function, oocyte maturation and embryo development, and in the implantation process. During ...

Liver Regeneration by Hematopoietic Stem Cells: Have We Reached the End of the Road?

Siapati E.K., Roubelakis M.G., Vassilopoulos G. (2022)

The liver is the organ with the highest regenerative capacity in the human body. However, various insults, including viral infections, alcohol or drug abuse, and metabolic overload, may cause chronic inflammation and ...

Making IVF more effective through the evolution of prediction models: is prognosis the missing piece of the puzzle?
