Medición de β-hCG procedente de líneas celulares de coriocarcionoma humano JEG-3 BeWo por QLIA

, 2021
Introduction: The cell lines JEG-3 and BeWo are clonal derivates of choriocarcinoma of human placenta and share some properties of immature human trophoblast cells, including the secretion of β-hCG, and thus they have been proposed as a trophoblast ...

Structural Variation Sequencing of 26 Amniotic Fluid Samples With Partial Gene Duplications and Postnatal Follow‐Up of the Fetuses

Prenatal Diagnosis, EarlyView.
ABSTRACT Objectives Partial gene duplications (PGDups) are a significant contributor to genetic disease. The precise genomic location and structure of PGDups are often unresolved using conventional methods, so prenatal diagnosis for PGDups is challenging, especially without ultrasound abnormalities.

Beta-Human Chorionic Gonadotropin and Uterine Artery Doppler Measurements for the Prediction of Success of Single Dose Methotrexate Treatment in Tubal Ectopic Pregnancies

Gynecology Obstetrics & Reproductive Medicine, 2016
Objectives: To evaluate the impact of the uterine artery Doppler values and the change of β-Human chorionic gonadotropin (β-HCG) levels from day 0 to day 4 for prediction of the success of single dose methotrexate treatment in tubal pregnancy cases ...

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

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

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.

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Case Report: Familial hCG syndrome with elevated hCG level concurrently in blood and cerebrospinal fluid

Frontiers in Endocrinology
ObjectiveTo describe a rare pediatric case of familial human chorionic gonadotropin (hCG) syndrome presenting with concurrent elevation of beta-hCG (β-hCG) in both blood and cerebrospinal fluid (CSF). This report aims to expand the phenotypic spectrum of
