Contents Heat-shock protein 70 (HSP70) plays a crucial role as intracellular cytoprotectant and molecular chaperone. A phenomenon of heat stress (HS) leads to production of these proteins that could be beneficial to cells during cryopreservation, whi

Biological molecules isolated from organisms that live under subzero conditions could be used to protect oocytes from cryoinjuries suffered during cryopreservation. This study examined the cryoprotectant role of exopolysaccharides of Pseudomonas sp.

Cryopreservation may lead bovine oocytes to undergo morphological changes and functional damage due to the high-lipid content in the cytoplasm and the formation of reactive oxygen species. Against this background, the present study aimed to improve t

Previous reports have demonstrated the beneficial effect of antifreeze glycoprotein supplementation during oocyte vitrification on preventing ice crystal formation and thus enhancing developmental competence after vitrification-warming. Pseudomonas s

In the present study we examined whether exposure to high concentrations of NaCl or sucrose before vitrification improves the cryotolerance of in vitro-matured bovine oocytes. In Experiment 1, oocytes were exposed to different concentrations of NaCl

The present study examined the relationship between the relative amount of high motile sperm and sperm-oocyte interactions obtained from Holstein bull ejaculates. Post-thaw sperm motility was analyzed using a computer-assisted sperm analyzer system a

After cryopreservation, oocytes may suffer morphological and functional damage, due to the high cytoplasm lipid content and to the reactive oxygen species formation. The aim of this work was to evaluate the spindle configuration and the DNA fragmenta

It has been previously described that a simple treatment with medium containing elevated NaCl or sucrose concentrations increases the cryotolerance and developmental competence of in vitro-matured porcine oocytes after vitrification and parthenogenet
