Physiological aspects of the β-core hCG fragment / Sebastiao Freitas de Medeiros
Analyses in detail a native small fragment of hCG/[beta] hCG subunit, the [beta]-core hCG fragment which is found in large amounts in urine and may be of clinical importance. The aims were to purify the fragment, analyse its protein and carbohydrate structure, develop direct assay methods for its …

PGE2 Receptor Subsets Mediate HCG Regulation of the Plasminogen Activator/Plasmin System in Primate Periovulatory Follicles
… ovulatory dose of human chorionic gonadotropin (hCG), or 36 hours after hCG from monkeys that received the prostaglandin (PG) synthesis inhibitor celecoxib. All EP receptor mRNAs were present in granulosa cells. By immunofluorescence, EP1 was detectable only 36 hours after hCG. EP2 and EP3 …

Biological effects of synthetic biomolecules that may either mimic or antagonise the function of hCG in the development of cancer and autoimmune disease
Human chorionic gonadotropin (hCG) is a hormone critical for successful pregnancy, partly by promoting maternal immune tolerance to fetal antigens. It achieves this by expanding immunoregulatory cells such as tolerogenic dendritic cells, regulatory T cells (Tregs), and regulatory B cells (Bregs). …

Enzyme activities associated with gonadotropic hormones
… homology between human chorionic gonadotropin (hCG) and α-chymotrypsin prompted the recent proposal of a tertiary structure of hCG using α-chymotrypsin as a folding template, which suggested the possibility of intrinsic peptidase activity associated with hCG. Highly purified hCG (CR127) was …

The MA-10 Cell Line as a Model of insl3 Regulation and Leydig Cell Function
… directly. The MA-10 Leydig cells treated with hCG exhibited a transient and robust increase in <em>nur77</em> mRNA, while <em>insl3</em> mRNA abundance remained unchanged. Further, cAMP failed to affect <em>insl3</em> mRNA, though <em>nur77</em> mRNA abundance was significantly increased. …

Ovarian sensitivity of the prepubertal ewe to exogenous gonadotropins
… after administration of 500 IU PMSG, 750 IU hCG, a combination of PMSG and hCG (500 IU PMSG followed by 250 IU hCG), 4, 8, 20, 30 or 40 mg of ovine pituitary extract or 12 mg of FSH-p.

Evaluation of biomarkers for the diagnosis, management and follow-up of women with gestational trophoblastic disease
… tissue. Human chorionic gonadotrophin (hCG) is an excellent biomarker for most forms of this disease as its concentration accurately reflects trophoblastic activity. Hydatidiform mole (HM) or molar pregnancy is the most common form of GTD which may be suspected on ultrasound but requires …

The impact of GnRH-agonist triggers on autologous in vitro fertilization outcomes: A retrospective analysis
… have been utilized as an alternative to hCG for oocyte maturation prior to follicle aspiration. GnRH-agonist triggers are proven to lower ovarian hyperstimulation syndrome risk, a condition that can be life threatening. Lower pregnancy rates have been reported in the literature with the …

Dietary Influence on Reproductive Development in Female Largemouth Bass, Micropterus Salmoides
… in the presence of human chorionic gonadotropin (hCG) to determine if there were differences in their ability to produce T and E2. Ovarian tissue from the pellet fed bass was less responsive to hCG in the later months of recrudescence, February and March. Testosterone and E2 production from small …

Entwicklung einer parallelen Mehrkomponentenanalyse von Antigen-Antikörper-Reaktionen in der Dopinganalyse
… wurde für das humane Choriongonadotropin (hCG-i) eine Konzentration von 10 mU/ml, für dessen beta-Untereinheit (hCG-beta) eine Konzentration von 3,6 mU/ml und für das luteinisierende Hormon (LH) eine Konzentration von 10 mU/ml bestimmt. Den ermittelten Wert im Serum für das hCG-i entspricht …

Microfabricated Surfaces and Particles for Advanced Immunoassay Platforms and High-Efficiency Electrowetting Heat Transfer System
… the detection of Human Chorionic Gonadotropin (hCG) on passivated acrylic surface, activated through the exposure to a helium atom beam, which is subsequently functionalized with anti-hCG antibodies. The positive sample microcubes that have been functionalized with anti-hCG and incubated with …

Evaluation of anaerobic membrane bioreactors and hydrothermal catalytic gasification for enhanced conversion of organic wastes to renewable fuels
… subcritical hydrothermal catalytic gasification (HCG) as an alternative to anaerobic digestion. HCG of a lignocellulosic feedstock (newspaper) with Raney nickel (Ra-Ni) catalyst at 350°C for 30 minutes was capable of gasifying the feedstock into a combustible syngas, but the catalyst lifetime was …

Analysis and characterisation of human chorionic gonadotropin glycoforms in pregnancy and trophoblastic disorders
Human chorionic gonadotropin (hCG) is a heterogeneous glycoprotein hormone with a varying degree of carbohydrate moieties. Its glycosylation arrangements are increasingly recognized as a common and important element of disease pathophysiology and are associated with many disorders including …

The effectiveness and efficiency of ovulation induction agents in mares
… 1: A retrospective analysis of the effects of hCG and deslorelin on the reproductive efficiency on two commercial horse farms. Reproductive data from two central Illinois horse farms was analyzed to compare the effectiveness of hCG (Chlorulon™) and a sustained release implant formulation of …

Analysis of methylation status of CGB genes in common nontrophoblastic cancer
hCG is a complex heterodimeric glycoprotein hormone essential during pregnancy. The hormone and its unique β-subunit are recognised tumour markers involved in enabling anti-apoptotic pathways, promotion of invasion and angiogenesis, and supporting tumour proliferation leading to more aggressive …
