BACKGROUND Human chorionic gonadotrophin (hCG) is measured in serum and urine for
the early detection of ectopic pregnancy, patients with higher risk of miscarriage, embryos or …

SINCE the discovery of human chorionic gonadotropin (hCG) by Hirose (1) and Ascheim
and Zondek (2) nearly three quarters of a century ago, its measurement has been the basis …

The objectives of this report is to improve the quality of immunochemical deter minations of
proteins. Procedures for determination of the various molecular forms hCG were chosen as …

BACKGROUND: Quantitative determination of human chorionic gonadotropin (hCG) in urine
is used in population studies of pregnancy disorders and in doping control. For these …

Glycoprotein hormones are noncovalent heterodimers comprised of a common α subunit
and a hormone-specific β subunit. Secretion and biologic action of these hormones are …

Human chorionic gonadotrophin (hCG) is the most discriminatory maternal serum marker of
Down's syndrome. We have carried out a study to establish whether urinary β‐core‐hCG, a …

The ability to reliably detect aberrant glycosylation of human chorionic gonadotropin (hCG)
may have profound implications for the diagnosis and monitoring of malignant gestational …

OBJECTIVE: To determine the stability of cytokines in frozen stored amniotic fluid samples,
we measured angiogenin, a potent inducer of neovascularization and interleukin-6, an …

Human gonadotrophins undergo metabolic transformations which result in the presence of
several smaller, structurally and immunologically related forms of gonadotrophins in the …

In this study, we proposed a pH-responsive photonic crystal hydrogel sensor (PCHs) to
conveniently and accurately recognize the amniotic fluid from urine of parturient women …
