Progestin-primed ovarian stimulation (PPOS) protocol has recently been demonstrated to be an novel regimen for preventing premature LH surges during controlled ovarian hyperstimulation (COH) in combination with frozen-thawed embryo transfer (FET). Our prospective controlled study was to explore the effect of human chorionic gonadotropin (hCG) contained in human menopausal gonadotropin (hMG) on ...

The nanogold reaction between HAuCl4 and citrate is very slow, and the catalyst graphene oxide nanoribbon (GONR) enhanced the nanoreaction greatly to produce gold nanoparticles (AuNPs) that exhibited strong surface plasmon resonance (SPR) absorption (Abs) at 550 nm and resonance Rayleigh scattering (RRS) at 550 nm. Upon addition of the peptide of human chorionic gonadotropin (hCG), the peptide ...

Objective We assessed the curative effect of a second curettage in patients with persistent hCG serum levels after first for gestational trophoblastic disease (GTD). Study Design This prospective observational study used data Belgian register GTD between July 2012 and January 2017. analysed who underwent curettage. included 313 database. Primary endpoints were need chemotherapy. Results Thirty-...

PURPOSE To investigate the effects of human chorionic gonadotropin (hCG) on the testicular tissue of young male rats. METHODS Male Wistar rats were assigned to groups (10 rats/group).Control Group received subcutaneous saline solution; Group 1 received hCG 50 UI/Kg/dose; and Group 2 received hCG 100 UI/Kg/dose, daily for 15 days. Half was submitted to bilateral orchiectomy on the 16th day and...

INTRODUCTION The aim of the present study was to evaluate the effects of fetal sex on serum human chorionic gonadotropin (hCG) and testosterone in normotensive and preeclamptic pregnancies. MATERIALS AND METHODS This is a cross-sectional study and 139 women with singleton pregnancies in the third trimester were studied. Seventy-one pregnancies were uncomplicated; among those were 35 male and ...

10658 Background: Apoptotic induction in cancer cells may improve the efficacy of local or systemic therapy. Human Chorionic Gonadotropin (HCG) injection directly into Kaposi's sarcoma or melanoma has been shown to increase the apoptotic index in these tumor types. The rapid induction of apoptosis in breast cancer immediately preceding local or systemic therapy may improve the response to thera...

OBJECTIVE To report an extremely rare case of spontaneous uterine perforation of choriocarcinoma with negative beta-human chorionic gonadotropin (β-hCG) post-chemotherapy. CLINICAL PRESENTATION AND INTERVENTION We present a 35-year-old choriocarcinoma patient whose serial serum β-hCG levels following a fifth course of chemotherapy had been within the normal range, but who developed spontaneou...

The hypothesis that rat seminal vesicles may contain luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptors was tested by means of a number of different techniques. Northern blotting demonstrated that rat seminal vesicles contained multiple LH/hCG-receptor transcripts. In situ hybridization revealed that these transcripts were present primarily in the principal epithelial cells l...

The term human chorionic gonadotropin (hCG) refers to a group of 5 molecules, each sharing the common amino acid sequence but each differing in meric structure and carbohydrate side chain structure. The 5 molecules are each produced by separate cells and each having separate biological functions. hCG and sulfated hCG are hormones produced by placental syncytiotrophoblast cells and pituitary gon...

Animal and 'in vitro' experiences learned that human chorionic gonadotropin (hCG) is capable to protect from breast cancer. Receptors for hCG/luteinizing hormone (LH) are present on human female and male breast cancer cells. hCG decreases proliferation and invasion of breast cancer MCF-7 cells by inhibiting NF-kappa B, AP-1 activation and other genes. Doxorubicin toxicity is enhanced by conjuga...
