Falsely increased plasma troponin (Tn) I and T results have been reported for several Tn methods, including the Beckman Coulter UniCel DxI AccuTnI assay (Beckman Coulter, Chaska, MN) (1–3). We and others have also observed falsely increased human chorionic gonadotropin (hCG) using the Beckman Coulter Access Total hCG on the UniCel DxI (1). These false increases were identified by the finding of...

The objectives of this study were to evaluate replacing GnRH with hCG and the effects of 48-h calf removal (CR) on pregnancy rates of cows synchronized with the CO-Synch protocol. Suckled beef cows (n = 467) at two locations were assigned to treatment by breed, age, and calving date. Treatment included either GnRH with (n = 121) or without CR (n = 117) or hCG with (n = 115) or without CR (n = 1...

background and purpose: the clinical outcome of intrauterine insemination (iui) treatment cycles employing a gonadotrophin-releasing hormone agonist [superfact)] or human chorionic gonadotrophin (hcg) for ovulation induction was compared. materials and methods: a group of 100 patients presenting with amenorrhoea, oligomenorrhoea or unexplained infertility were all treated with clomiphene 100 mg...

OBJECTIVES Some intracranial germinomas, which may contain syncytiotrophoblastic giant cells (STGCs), are associated with a mildly to moderately increased human chorionic gonadotropin (HCG) concentration in serum, and patients with such germinomas are thus treated more aggressively than those with "pure" germinoma. However, the patients with germinoma and detectable HCG in CSF but not in serum ...

Human chorionic gonadotrophin (hCG) is a hormone produced during pregnancy and present at the implantation site and in the maternal blood. Pregnancy has been proposed to represent a controlled state of inflammation at an early stage at the implantation site and later, systemically extended to the maternal circulation. Earlier, we reported that hCG can inhibit the development of diabetes in NOD ...

The corpus luteum (CL) forms after ovulation and acts as a temporary endocrine gland that produces progesterone (P4), a hormone that is essential for implantation and maintenance of pregnancy in mammals. In pregnant women, human chorionic gonadotropin (hCG) secreted by the conceptus prevents luteolysis. hCG also increases the survival of cultured human luteinized granulosa cells (hLGCs). To cla...
