The Effect of Linolenic Acid on Bovine Oocyte Maturation and Development1
Dietary polyunsaturated fatty acids can influence reproductive performance. In dairy cattle, some high-fat diets resulted in higher blastocyst rates and improved embryo quality. These effects may… Expand

Impact of linoleic acid on bovine oocyte maturation and embryo development.
Linoleic acid (LA; 18:2 n-6) is the most abundant fatty acid in bovine follicular fluid, and it was previously reported that LA concentration significantly decreases when follicle size increases.… Expand

Role of hyaluronic acid in maturation and further early embryo development of bovine oocytes.
Hyaluronic acid (HA), an important component of the extracellular matrix, plays a crucial role for cumulus cell expansion. Genes and proteins involved in HA synthesis and its receptor CD44 are… Expand

Protective effects of antioxidants on linoleic acid-treated bovine oocytes during maturation and subsequent embryo development.
Linoleic acid (LA; n-6, 18:2) is the most abundant polyunsaturated fatty acid in the ovarian follicular fluid and is known to inhibit oocyte maturation and its subsequent development. In the present… Expand

Proteomic changes in oocytes after in vitro maturation in lipotoxic conditions are different from those in cumulus cells
Maternal lipolytic metabolic disorders result in a lipotoxic microenvironment in the ovarian follicular fluid (FF) which deteriorates oocyte quality. Although cellular stress response mechanisms are… Expand

Differential effects of linoleic and alpha-linolenic fatty acids on spatial and temporal mitochondrial distribution and activity in bovine oocytes.
Using specific stains and confocal microscope imaging, the patterns of mitochondrial distribution, mitochondrial inner membrane potential and reactive oxygen species (ROS) levels during bovine oocyte… Expand

Role of PTGS2-generated PGE2 during gonadotrophin-induced bovine oocyte maturation and cumulus cell expansion.
Prostaglandin E2 (PGE2) is an autocrine/paracrine factor which mediates gonadotrophin (Gn) stimulation of cumulus expansion and oocyte maturation in rodents. Its role in bovine oocyte maturation is… Expand

Perspectives of nanotechnology in male fertility and sperm function
Abstract Recent advances in nanotechnology have tremendously expanded its possible applications in biomedicine. Although, the effects of nanoparticles (NPs) at cellular and tissue levels have not… Expand

From mRNA Expression of Drug Disposition Genes to In Vivo Assessment of CYP-Mediated Biotransformation during Zebrafish Embryonic and Larval Development
The zebrafish (Danio rerio) embryo is currently explored as an alternative for developmental toxicity testing. As maternal metabolism is lacking in this model, knowledge of the disposition of… Expand
