Early pregnancy termination with mifepristone and misoprostol in the United States.
BACKGROUND Mifepristone and a prostaglandin have been used successfully to terminate pregnancy in Europe and China. We report the results of a large U.S. study of mifepristone and misoprostol inExpand

Differential regulation of steroidogenic enzymes during differentiation optimizes testosterone production by adult rat Leydig cells.
The postnatal differentiation of rat Leydig cells may be subdivided into three stages based on morphology and steroid production. The purpose of this study was to clarify the developmental mechanismsExpand

Inhibin, a gonadal hormone capable of preferential suppression of pituitary follicle-stimulating hormone (FSH) secretion, has recently been purified. The major form of this protein is an alpha betaExpand

Purification of gonadotropin surge-inhibiting factor from Sertoli cell-enriched culture medium.
Gonadotropin surge-inhibiting factor (GnSIF) is a novel biological factor in follicular fluid that inhibits the pre-ovulatory LH and FSH surges. Recent studies suggest that the biological activity ofExpand

Episodic luteinizing hormone secretion in man. Pulse analysis, clinical interpretation, physiologic mechanisms.
The demonstration that luteinizing hormone (LH) release from the pituitary is episodic rather than constant raises fundamental questions regarding the physiologic control of pulsatile LH secretionExpand

Primary structure of human corticosteroid binding globulin, deduced from hepatic and pulmonary cDNAs, exhibits homology with serine protease inhibitors.
We have isolated and sequenced cDNAs for corticosteroid binding globulin (CBG) prepared from human liver and lung mRNAs. Our results indicate that CBG mRNA is relatively abundant in the liver but isExpand

erythro-9-[3-(2-Hydroxynonyl)]adenine is an inhibitor of sperm motility that blocks dynein ATPase and protein carboxylmethylase activities.
Protein carboxylmethylase (S-adenosyl-L-methionine:protein O-methyltransferase, EC is believed to be involved in the regulation of sperm motility. To test this hypothesis, we investigatedExpand

Mifepristone (RU 486)--a modulator of progestin and glucocorticoid action.
Antiprogestins, agents that inhibit the action of progesterone, are among the most controversial and yet the more interesting therapeutic compounds developed in the past 20 years. These agentsExpand

Changes in the distribution of intermediate filaments in rat Sertoli cells during the seminiferous epithelium cycle and postnatal development
Intermediate filaments (IFs) are components of the cytoskeleton. In mammalian Sertoli cell, IFs are formed by vimentin. Previous studies have shown some characteristics of its distribution in SertoliExpand

The cDNA‐deduced primary structure of human sex hormone‐binding globulin and location of its steroid‐binding domain
We have sequenced a cDNA for sex hormone‐binding globulin (SHBG) isolated from a phage λgt 11 human liver cDNA library. The library was screened with a radiolabeled rat androgen‐binding protein (ABP)Expand
