To evaluate the role of human chronic gonadotropin (HCG) and compare the results when it is given preoperatively and postoperatively in bilateral nonpalpable undescended testes (BNUDT) to facilitate the surgical outcome. Sixty-six cases of BNUDT, from January 1997 to January 2004, were divided equally into two groups on a random basis: Group A – control group received HCG doses which were compl...

Background. Although the association between human chorionic gonadotropin (hCG) and hyperandrogenism was identified more than 40 years ago, relevant questions remain unanswered. Design and Methods. We conducted a prospective, longitudinal, and controlled study in 23 women with a diagnosis of a complete hydatidiform mole (HM). Results. All participants completed the study. Before HM evacuation m...

Knowing the epitope specificities of our monoclonal antibodies (MCA) to human choriogonadotropin (hCG), we could design three classes of two-site immunoradiometric assays (IRMA): a combinationof two MCA recognizingtwo separate a-epitopes (a-MCA) provides a system (i.e., an a-IRMA) that measures holo-hCG plus free a-subunitsplus follitropin, lutropin, and thyrotropin, whereas a /3-IRMA, consisti...

In 25 cases of triploidy at 10-14 weeks of gestation, compared with 947 controls, the median multiple of the median (MoM) fetal nuchal translucency (NT) thickness was significantly increased (1.89 MoM), and maternal serum total and free beta-human chorionic gonadotrophin (hCG) were increased (3.13 MoM and 4.59 MoM respectively), alpha fetoprotein (AFP) was increased (2.14 MoM), and pregnancy as...

Deep B and R images of three Hickson Compact Groups, HCG 79, HCG 88 and HCG 95, were analyzed using a new wavelet technic to measure possible intra-group diffuse light present in these systems. The method used, OV WAV, is a wavelet technic particularly suitable to detect low-surface brightness extended structures, down to a S/N = 0.1 per pixel, which corresponds to a 5-σ-detection level in wave...

It is now evident that human chorionic gonadotropin (hCG) is not a single molecular entity but consists of a number of different biologically active components [l-4]. By means of gel isoelectric focusing 6 hCG forms recently could be isolated and characterized [2-41. Furthermore it is well established that hCG is composed of 2 subunits: hCG-a (common to other proteohormones) and hCH-fl (hormone...

A 27-year-old second gravid was admitted with history of amenorrhea of 8 weeks’ duration with lower abdominal pain and spotting per-vaginum of 2 days’ duration. Her vitals were stable, and abdominal examination revealed a soft bulky 6 weeks’ size uterus. Cervical motion tenderness was absent. In view of a positive urine pregnancy test, an urgent transvaginal ultrasound was performed, which reve...

This paper focuses on the indirect adaptive tracking control of renewable energy sources in a grid-connected hybrid power system. The renewable energy systems have low efficiency and intermittent nature due to unpredictable meteorological conditions. The domestic load and the conventional charging stations behave in an uncertain manner. To operate the renewable energy sources efficiently for ha...

The optimal time period for intrauterine insemination (IUI) in relation to either luteinizing hormone (LH) surge or human chorionic gonadotrophin (HCG) administration leading to the best pregnancy rates has not been determined. In this study, 856 consecutive human menopausal gonadotrophin (HMG)-stimulated and 49 natural unstimulated IUI cycles carried out at a reproductive medicine unit affilia...
