Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

LOCALIZATION, DISTRIBUTION AND SECRETION OF β-SUBUNIT OF HUMAN CHORIONIC GONADOTROPIN IN NORMAL HUMAN CHORIONIC TISSUE

ACTA HISTOCHEMICA ET CYTOCHEMICA, 1979
Glycoproteins, including human chorionic gonadotropin (hCG), though not of pituitary origin, consist of two subunits, namely α- and β-subunit. Wide attention has been paid to the activities of β-subunit of those hormones not only biologically but immunologically, in regard to clinical interests.

Detection of the GH Analogue Redalsomatropin Alfa in Sports Drug Testing: Immunological Approaches and LC‐HRMS/MS

Drug Testing and Analysis, EarlyView.
After evaluating the compatibility of the GH analogue redalsomatropin alfa with approved doping control immunoassays for rhGH, it was implemented into the existing detection method for somatrogon employing affinity purification with GHR‐Fc‐conjugated magnetic beads, tryptic digestion, and LC‐HRMS/MS to allow for a specific and sensitive detection ...

The utility of serum markers in the conservative management of placenta accreta spectrum (PAS) by leaving the placenta in situ in women with high‐grade PAS

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To investigate the association between serum markers and successful conservative management of patients with placenta accreta spectrum (PAS). Methods This was a retrospective case–control study where patients with high‐grade PAS between 2011 and 2025 undergoing conservative leaving the placenta in situ were included.

The Role of Human Chorionic Gonadotropin Beta (hCGβ) in HPV-Positive and HPV-Negative Oropharyngeal Squamous Cell Carcinoma [PDF]

, 2022
SIMPLE SUMMARY: Oropharyngeal squamous cell carcinoma (OPSCC) is often associated with human papillomavirus (HPV). The management of OPSCC remains a challenge, and HPV-negative disease is commonly associated with impaired survival.

Comparison of four different analyzers for prenatal trisomy 21 risk

Advances in Laboratory Medicine
Various analyzers are available for measuring first-trimester combined screening for trisomy 21 (T21) serum biomarkers (free-beta subunit of the human chorionic gonadotropin (β-hCG) and the pregnancy-associated plasma protein A (PAPP-A)).

A new contingent screening strategy increased detection rate of trisomy 21 in the first trimester

BMC Pregnancy and Childbirth, 2023
Background Although the traditional contingent screening strategy is effective, there are still undetected low-risk trisomy 21. This study aims to define appropriate cut-off values of serum biochemical markers at low-risk and develop a strategy for ...

Fetal Heart Rate at 12 Weeks' Gestation and the Risk of Preterm Birth

Journal of Ultrasound in Medicine, EarlyView.
Objectives To prospectively validate the association between fetal heart rate (FHR) at the 12‐week scan and the risk of preterm birth (PTB), including spontaneous preterm birth (sPTB). Methods This prospective cohort study included 1276 singleton pregnancies undergoing routine first‐trimester screening at 11–13 + 6 weeks' gestation and followed until ...
