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 …

Electrochemical immunosensor based on cyclodextrin supramolecular interactions for the detection of human chorionic gonadotropin
… electrochemical strategies for the detection of human chorionic gonadotropin(hCG) is presented. This involves the modification of a gold surface with a thiolated β-cyclodextrin epichlorohydrin polymer (βCDPSH) to form a supramolecular inclusion complex with ferrocene (Fc)-functionalised …

Vasculogenic mimicry in bladder cancer and its association with cancer stem cells and human chorionic gonadotropin-beta
… studies have demonstrated the involvement of human chorionic gonadotrophin-beta (hCG-beta) in the development of VM in some types of cancer such as ovarian cancer, cervical cancer, testicular cancer and hepatocellular carcinoma. However, there is not much research performed on the role of …

Regulation of Expression of 5 Alpha-Reductase Type 1 in Mouse Leydig Cells
… for development of the male phenotype in human beings. However, in some animals, androstanediol, a 5a-reduced androgen, is the primary androgen produced by the testis during certain stages of development, indicating the presence of 5a-reductase in the testis itself. Studies in mice show …

Effects of Estradiol on Leydig Cell Function and Testicular Development in the Prepubertal Bull
… and 31 weeks with an intramuscular injection of human chorionic gonadotropin (hCG). Serum hormone levels were determined weekly. At 39 weeks of age, E and P calves were castrated for histologic evaluation of the testes and assessment of in vitro Leydig cell function. Serum E$\sb2$ was greater …

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). …

Dietary Influence on Reproductive Development in Female Largemouth Bass, Micropterus Salmoides
… T and E2 can exert negative feedback effects on gonadotropin secretion from the pituitary. Because diet did influence gonadal growth, ovarian tissue from bass raised on both diets was incubated in vitro in the presence of human chorionic gonadotropin (hCG) to determine if there were differences …

In vitro progesterone and estrone synthesis by the porcine placenta and endometrium at 30, 60 and 90 days of gestation
… of the effects of pregnenolone (P₅), human chorionic gonadotropin (hCG) and 3' 5', cyclic adenosine monophosphate ( cAMP) on porcine placental and endometrial production of progesterone (P₄), testosterone (T) and estrone (E₁) at 30, 60 and 90 days of gestation. Duplicate 300 mg samples …

Recruitment of monocytes to the pre-ovulatory ovary
… Ovaries were collected at several times post human chorionic gonadotropin (hCG) injection and analyzed by multi-color flow cytometry. Oviducts were collected from mice 20 hours after hCG administration and cumulous oocyte complexes were collected, counted and averaged to determine ovulation …

Evaluating luteinizing hormone receptor signaling using the cyclic AMP reporter ICUE3
… conditions including exposure of cells to human chorionic gonadotropin (hCG). In some experiments, CHO cells co-expressing ICUE3 and constitutively-active LH receptors, LH receptors yoked to a single-chain modified form of hCG (yLHR), were used to determine whether the presence of a …

Towards Early State Disease Detection in Microdevices: Fabrication and Testing of Micro Total Analysis Systems for Bioanalytical Applications
… Selective preconcentration and elution of human chorionic gonadotropin have been performed in my affinity columns, demonstrating that this type of system should have promising applications in cancer marker detection.</p>

Hormonal mechanisms for variation in female mate choice
… hormone concentration was manipulated using human chorionic gonadotropin (HCG) and such manipulation induces flexible mate choice. Finally, I investigate whether hormones modulate a central auditory nucleus involved in phonotaxis behavior. Immediate early gene (IEG) induction, specifically …

Superfetation in beef cattle
… by induction of ovulation in mated cattle with human chorionic gonadotropin (hCG) followed by AI was unsuccessful. Ovulation was induced in pregnant cows on day 7 but could not be induced >23 days of pregnancy. Subsequently, it was shown that uterine stage bovine embryos (7-day) could develop …

Development of Bioassays Based on Nucleic Acid Amplification and Next-Generation Sequencing
… DNA PCR target into each nanoparticle. Using human chorionic gonadotropin hormone (hCG) as a model analyte, this platform was able to quantitate the target hCG protein in femtomolar concentrations using only standard laboratory equipment.
