First‐Trimester Crown‐Rump Length and Large for Gestational Age Newborns: What Correlation?

Journal of Clinical Ultrasound, EarlyView.
Our research found for the first time that uneventful pregnancies with LGA neonates are characterized by larger than expected CRL at the first trimester. CRL is one of the new markers that can be used to early identify fetuses at risk of increased fetal growth.

Retroperitoneal Leiomyosarcoma Associated with an Elevated β-HCG Serum Level Mimicking Extragonadal Germ Cell Tumor

, 2000
Patient.A 65-year-old man was admitted with a large primary retroperitoneal tumor and an increased β-human chorionic gonadotropin (β-HCG) serum level. A germ cell tumor was suspected; however, a computed tomography-guided biopsy failed to enable tumor ...

Strategies for enhancing sensitivity in lateral flow assays

VIEW, EarlyView.
Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural

Combined analysis of estradiol and β-hCG to predict the early pregnancy outcome of FET: a retrospective study

Journal of Ovarian Research
Background The accurate prediction of pregnancy outcomes in in vitro fertilization (IVF) cycles is crucial. While several studies have been conducted on the predictive power of serum estradiol (E2) and β-hCG concentrations post-embryo transfer (ET) for ...

Differences between the discriminatory activity of antisera raised against the total gonadotropins and the Pr-β-hCG-TT for neutralization of hCG and LH action

, 1978
The effect of antibodies from four monkeys immunized with the vaccine Pr-β-hCG-TT has been investigated on LH/hCG induced progesterone synthesis by goat granulosa cells in culture. The antisera in all cases blocked the hCG induced steroidogenesis.

Analytical and clinical evaluation of a human chorionic gonadotrophin plus β (hCG + βhCG) immunoassay in germ cell tumours and gestational trophoblastic disease

, 2005
Background. - In gestational trophoblastic disease (GTD) and germ cell tumours (GCT), irregular human chorionic gonadotrophin (hCG) forms may be the principal source of immunoreactivity.

Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

Andrology, EarlyView.
Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.
