BACKGROUND The zona pellucida (ZP), an extracellular matrix which surrounds mammalian oocytes, is formed by different glycoproteins. Several studies have revealed that carbohydrate residues present(More)
Lectins from peanuts (PNA) and soy beans (SBA) bind terminal residues of galactose (Gal) and N-acetyl-galactosamine (GalNAc) respectively. Galactose oxidase oxidizes the hydroxyl group at C-6 of(More)
In a previous study, evidence was provided for the presence of a novel plasma-membrane-associated neutral-pH-optimum alpha-L-fucosidase in rat sperm. In the present study, rat sperm(More)
Our previous studies have shown that morphine withdrawal increases the hypothalamic–pituitary–adrenocortical axis activity, which is dependent on a hyperactivity of noradrenergic pathways (nucleus(More)
