Background: Patients with ectopic pregnancy and low serum β-HCG concentrations are commonly treated systemic methotrexate. Aim: To compare the outcome of methotrexate versus expectant management for females presenting pregnancy. Study design: Randomized controlled trial. Methodology: Females (n=140) were enrolled in study. Blood sample was taken beta-HCG noted. Then randomly divided two groups ...

We present data on the stellar kinematics of the brightest ellipticals in HCG 62, HCG 68, NGC 2300 groups. Moreover, we report on ASCA GIS as well as optical observations of the early-type member of the pair K 416 (NGC 5480/5481) similar, in many respects, to the dominant pair in the NGC 2300 group. The kinematics of HCG 62a/b and HCG 68a/b indicate that they are not interacting pairs. HCG 62a ...

BACKGROUND Patients with trophoblastic diseases produce ordinary and irregular forms of human chorionic gonadotropin (hCG; e.g., nicked hCG, hCG missing the beta-subunit C-terminal segment, hyperglycosylated hCG, and free beta subunit) that are recognized to differing extents by automated immunometric hCG (or hCG beta) assays. This has led to low or false-negative results and misdiagnosis of pe...

Background: The -subunit of human chorionic gonadotropin (hCG) is encoded by four genes, of which expression of the hCG -3, -5, and -8 genes could have prognostic value in breast cancer. Methods: Applying a new, modified Molecular Beacon reverse transcription-PCR assay, we investigated the prognostic value of the hCG -3, -5, and -8 gene transcripts in 129 sporadic unilateral breast cancer sampl...

OBJECTIVE To examine whether in smokers there is a significant dose dependency between the number of cigarettes per day and levels of free ss-hCG and pregnancy-associated plasma protein A (PAPP-A) at 11-13(+6) weeks of gestation. METHODS This was a retrospective analysis of the maternal serum free ss-hCG and PAPP-A levels in relation to the maternal smoking status in 109 263 chromosomally nor...

OBJECTIVE In a prospective multicenter trial, it was our intention to elucidate clinical prognostic factors of seminomas with special reference to the importance of human chorionic gonadotropin (HCG) elevations in histologically pure seminomas. METHODS Together with 96 participating urological departments in Germany, Austria, and Switzerland, we recruited 803 seminoma patients between 1986 an...

Prenatal diagnosis of chromosomal aneuploidies is the most frequent prenatal test offered to pregnant women. In most cases, they are recommended in the following circumstances: maternal age of 35 years or above; positive firstor second-trimester screening test results, and increased risk of fetal aneuploidies due to family history. During the first trimester, screening tests include: nuchal tra...

Aim Human chorionic gonadotropin (hCG) is used frequently for luteal support in fresh in vitro fertilization cycles as it induces progesterone secretion from the ovaries after oocyte retrieval and modulates the endometrium for implantation in fresh cycles. In contrast, hCG is not usually used for the transfer of cryopreserved-thawed embryos in estrogen/progesterone replacement cycles because ov...
