ZP3, a preparation of the 55K families of porcine oocyte zona pellucida, possesses carbohydrate-dependent ligand activity for boar sperm. The aim of the present study was to analyze ZP3 N- and O-linked oligosaccharides with respect to size distribution, composition, and role in sperm-zona recognition events. Digestion of denatured ZP3 with peptide(More)
The distribution of O-linked oligosaccharides on the M(r) 55,000 glycoproteins, ZP3 alpha and ZP3 beta, of the porcine oocyte zona pellucida was examined. Purified preparations of endo-beta-galactosidase digested ZP3 alpha and ZP3 beta were reduced and carboxamidomethylated and digested with trypsin. When the trypsin digests were mapped by HPLC, each(More)
There is no cure for sickle cell disease. In management our emphasis is on maintenance and palliative treatment. Preventive care, which includes regular medical supervision, adequate nutrition, and sufficient fluid intake, is also desirable. They will be discussed throughout this symposium. We must be instrumental in helping people with sickle cell disease(More)
There has been an increasing interest in the sulfate conjugates of estrogens as important metabolites in steroid hormone homeostasis and activity. In women estrogen sulfates have been known as major components of plasma originating from ovarian secretion and hepatic metabolism. However, only recently has the capacity to sulfurylate estrogens been(More)
Human endometrial curettings were selected principally from patients undergoing tubal ligations for elective sterilization. Specimens were analyzed for the metabolism of 17beta-[6,7-3H]estradiol and Na2 35SO4; assayed for the nuclear receptor content with 17beta-[6,7-3H]estradiol; and examined for the cytosol receptor content with(More)
