The effectiveness of DNA vaccination alone is limited, because it often generates only a weak cellular immune response; therefore, the complementary use of adjuvants may be required to improve vaccine potency and enhance its immune protective effects. The present study aimed to determine the effect of recombinant DNA vaccine-based human hcg and survivin on the development of breast carcinoma in...

Abstract Study question How can stimulation of corpus luteum in the luteal phase with human chorionic gonadotropin (hCG) improve obstetric and perinatal outcomes? Summary answer There is currently no evidence that use hCG as an alternative treatment for luteal-phase support (LPS) improves outcomes. What known already are different approaches providing LPS, although none have shown differences p...

Purpose Recombinant hCG (r-hCG) was approved in Japan in 2016. As a prerequisite for a Phase III study in Japan related to this approval, the pharmacokinetic (PK) profile of r-hCG was investigated. Methods An open-label, partly randomized, single-center, single-dose, group-comparison, Phase I PK-bridging study was done that compared a single 250 μg dose of r-hCG with a single 5000 IU dose of ...

BACKGROUND Recently, it has been demonstrated that, in patients down-regulated by GnRH analogues (GnRHa), a short-term pre-treatment with recombinant LH (rLH), prior to recombinant FSH (rFSH) administration, increases the number of small antral follicle prior to FSH stimulation and the yield of normally fertilized embryos. However, no data exist in the literature regarding the potential benefic...

Human chorionic gonadotrophin (hCG) is secreted during early pregnancy and is required for implantation and maintenance of the pregnancy. Active or passive immunoneutralization of hCG results in termination of pregnancy and this forms the basis of the hCG-based female contraceptive vaccine. However, the beta subunit of hCG possesses 85% sequence homology with the first 114 amino acids of the be...

Vascular endothelial growth factor (VEGF) has been identified as an endothelium-specific mitogen and inducer of angiogenesis and endothelial cell survival. Leptin and hCG have also been suggested as possible regulators of angiogenesis in various models. In-vivo and in-vitro assays revealed that leptin has an angiogenic activity and that the vascular endothelium is a target for leptin. Thus, we ...

Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) are widely recognized for their roles in ovulation and the support of early pregnancy. Aside from the timing of expression, however, the differences between LH and hCG have largely been overlooked in the clinical realm because of their similar molecular structures and shared receptor. With technologic advancements, including the de...

Modern analytical approaches employing high-resolution mass spectrometry (MS) facilitate the generation of a vast amount structural data highly complex glycoproteins. Nevertheless, systematic interpretation this at different levels remains an challenge. The glycoprotein utilized as model system in study, human chorionic gonadotropin (hCG), exists heterodimer composed two heavily glycosylated su...

In cystic fibrosis (CF), large amounts of free leucocyte proteases are present in bronchial secretions, contributing to progressive lung damage. Recombinant, human deoxyribonuclease (rhDNase) is a new therapeutic agent that decreases sputum viscosity. However, deoxyribonuclease has been shown, in vitro, to release cationic enzymes from complexes with deoxyribonucleic acid (DNA). The present stu...

The efficacy of follicle stimulating hormone (FSH) as an alternative to luteinizing hormone (LH)/human chorionic gonadotrophin (HCG) for the initiation of periovulatory events in primate follicles is unknown. A single bolus of 2500 IU recombinant (r)-hFSH was compared to 1000 IU r-HCG for its ability to promote oocyte nuclear maturation and fertilization, granulosa cell luteinization and corpus...
