Aim. To analyse the levels of serum beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein A (PAPP-A) in pregnant women without fetal chromosomal abnormalities with trisomy 21 (Down syndrome) or 18 (Edwards syndrome). Materials Methods. We performed a retrospective analysis biochemical parameters 1214 who had previously undergone karyotyping as part prenatal postnatal...

We present the interferometric measurements of 2.6 mm CO (J = 1 ! 0) emission (F W HM 5 00) and the analysis of IRAS HIRES images of two Hickson Compact Groups HCG 31 and HCG 92 (\Stephan's Quintet"). The far infrared (FIR) emission is concentrated to a single region in HCG 31 while it is clearly extended and peaks near the group center in HCG 92. CO emission is weak in HCG 31, and the brightes...

OBJECTIVE To evaluate pregnancy outcomes and the incidence of ovarian hyperstimulation syndrome (OHSS) using a sliding scale hCG protocol to trigger oocyte maturity and establish a threshold level of serum b-hCG associated with optimal oocyte maturity. DESIGN Retrospective cohort. SETTING Academic medical center. PATIENTS Fresh IVF cycles from 9/2004-12/2011. INTERVENTION 10,427 fresh I...

Analyses of B and R band observations of four compact groups reveal the presence of a considerable amount of diffuse, intergalactic light in two of them (HCG 79 and HCG 95). The diffuse component is presumably due to stellar material that has been tidally stripped from the galaxy group members. A new approach is used to measure this diffuse background light, using wavelet techniques for detecti...

The effective detection of human chorionic gonadotropin (HCG) is considerably important for the clinical diagnosis both early pregnancy and nonpregnancy-related diseases. In this work, a simple sensitive electrochemical sandwich-type immunosensing platform was designed by synthesizing b-cyclodextrin (CD) functionalized graphene (CD/GN) hybrid as simultaneously sensing signal transducer coupled ...

The IVM of canine oocytes is characterized by low rates of metaphase II. The objective of this study was to evaluate the effects of hCG on meiotic development of canine oocytes for culture periods up to 96 h. Oocytes were collected after ovariohysterectomy. Only oocytes >110 microm in diameter, with a homogeneous dark cytoplasm and three or more layers of compact cumulus cells were used. For IV...

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...

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...
