First-trimester or second-trimester screening, or both, for Down's syndrome [PDF]
BACKGROUND: It is uncertain how best to screen pregnant women for the presence of fetal Down's syndrome: to perform first-trimester screening, to perform second-trimester screening, or to use strategies incorporating measurements in both trimesters ...

Ability of human chorionic gonadotropin β-subunit to inhibit the steroidogenic response to lutropin [PDF]
Ability of the beta-subunit of human chorionic gonadotropin to inhibit the response to lutropin (luteinizing hormone, LH) was tested in the immature rat ovarian system and pregnant-mare-serum-gonadotropin-primed rat ovarian system with progesterone production being used as the response.

Making of a unique birth control vaccine against hCG with additional potential of therapy of advanced stage cancers and prevention of obesity and insulin resistance [PDF]
Reviewed is the work which led to the development of a unique vaccine that prevents pregnancy in sexually active women without impairment of ovulation and block of their making normally their sex steroid hormones. Being given that hCG is not expressed by

The linear amino acid sequence of the α subunit of human chorionic gonadotropin (hCG-α) has been derived from a study of the tryptic and cyanogen bromide peptides. The total number of amino acids varies from 89 to 92 because of NH2-terminal heterogeneity probably caused by proteolysis of hCG.

Hyperprolactinemia induced by hCG leads to metabolic disturbances in female mice [PDF]
The metabolic syndrome is a growing epidemic; it increases the risk for diabetes, cardiovascular disease, fatty liver, and several cancers. Several reports have indicated a link between hormonal imbalances and insulin resistance or obesity.

Various carboxyl-terminal peptides of hCG-β were prepared from the corresponding blocked peptides by TFA treatment followed by hydrogenation. The prepared peptides were tested for inhibitory action on the binding between 125I-hCG and the antiserum against the carboxyl-terminal portion of hCG-β.

Origin and Occurrence of Human Chorionic Gonadotropin β-Subunit Core Fragment [PDF]
Human chorionic gonadotropin (hCG) beta-subunit core fragment (beta-fragment) is present in the urine of pregnant individuals as well as those with trophoblast disease and certain other cancers at concentrations 0.8 (early pregnancy) to 7 (second trimester pregnancy)-fold greater than that of hCG.

The amino acid sequence of human chorionic gonadotropin. The alpha subunit and beta subunit.
The amino acid sequences of both the alpha and beta subunits of human chorionic gonadotropin have been determined. The amino acid sequence of the alpha subunit is: Ala - Asp - Val - Gln - Asp - Cys - Pro - Glu - Cys-10 - Thr - Leu - Gln - Asp - Pro - Phe - Ser - Gln-20 - Pro - Gly - Ala - Pro - Ile - Leu - Gln - Cys - Met - Gly-30 - Cys - Cys - Phe ...
