Aim The refinement of assisted reproductive technology, including the development of
cryopreservation techniques (vitrification) and ovarian stimulation protocols, makes frozen …

l-carnitine is a potent antioxidant used for in vitro culture systems. Controversial results have
been reported using l-carnitine in culture medium at different stages of in vitro bovine …

Culture environment during in vitro embryo production can affect embryo phenotype and
pregnancy outcomes, making culture modifications a logical approach for improving embryo …

Vitrification negatively affects the mitochondrial membrane potential (ΔΨm) in oocytes while
also leading to increased reactive oxygen species (ROS), ATP depletion and induction of …

Early embryo development is driven first by the maternal RNAs and proteins accumulated
during the oocyte's cytoplasmic maturation and then after the embryo genome activation. In …

The effects of acetyl-l-carnitine (ALC) supplementation during IVM on subsequently vitrified
buffalo oocytes were evaluated, followed by determination of the mitochondrial DNA copy …

Hyperuricemia (HUA) is associated with left ventricular remodeling (LVR) and thereby
causes the initiation and development of a large number of cardiovascular diseases. LVR is …

Circular RNAs (circRNAs) are a new class of endogenous RNA regulating gene expression.
However, the regulatory mechanisms of lipid metabolism in yaks involved in circRNAs …

In the present study, we aimed to identify morphological and molecular changes of in vivo
and in vitro-produced goat embryos submitted to cryopreservation. In vivo embryos were …

The technique of oocyte vitrification remains a challenge in most animal species. The
present study aimed to evaluate the effects of cumulus cell presence and L‐carnitine (LC) …
