Human amniotic fluid glycoproteins expressing sialyl Lewis carbohydrate antigens stimulate progesterone production in human trophoblasts in vitro [PDF]

, 2004
Background: Progesterone is thought to mediate immune modulator effects by regulating uterine responsiveness. The aim of the study was to clarify the effect of transferrin and glycodelin A (former name PP14) as sialyl Lewis X-expressing glycoproteins on ...

Ovarian Masses in Children and Adolescents: A Review of the Literature with Emphasis on the Diagnostic Approach

Children, 2023
Most abdominal masses in the pediatric population derive from the ovaries. Ovarian masses can occur in all ages, although their incidence, clinical presentation and histological distribution vary among different age groups.

Intracellular folding pathway of human chorionic gonadotropin beta subunit.

Journal of Biological Chemistry, 1992
Few experimental models have been used to investigate how proteins fold inside a cell. Using the formation of disulfide bonds as an index of conformational changes during protein folding, we have developed a unique system to determine the intracellular folding pathway of the beta subunit of human chorionic gonadotropin (hCG).

A mass-forming cystic appearance of peritoneal recurrence of gastric adenocarcinoma

Journal of Cancer Research and Practice, 2018
Metastatic peritoneal tumors of gastric origin usually appear as multiple small nodules on the peritoneal surface or as scirrhous-type infiltrating lesions. A mass-forming cystic appearance is highly unusual and is unique to peritoneal metastasis. Herein,

The beta subunit of human chorionic gonadotropin is encoded by multiple genes.

Journal of Biological Chemistry, 1983
Two recombinant phage clones bearing sequences corresponding to the beta subunit of human chorionic gonadotropin (hCG beta) were isolated from a human genomic library. The beta sequences were mapped by blot hybridization of restriction digests of these phage DNAs and the nonoverlapping inserts were subcloned in pBR322 and sequenced.

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.

Mola hidatiforme e doença trofoblástica gestacional Hydatidiform mole and gestational trophoblastic disease

Revista Brasileira de Ginecologia e Obstetrícia, 2009
A mola hidatiforme é uma complicação relativamente infrequente da gravidez, mas com potencial para evolução para formas que necessitam de tratamento sistêmico e podem ser ameaçadoras da vida.

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

Sonographic vascularity indices' study in ectopic pregnancies, after methotrexate treatment

European Journal of Obstetrics & Gynecology and Reproductive Biology: X
Objectives: Ectopic pregnancy is a crucial problem in Gynaecology. Previous studies concerning the medical treatment of ectopic pregnancies, have used only β-hCG (beta- human chorionic gonadotropin) values, to monitor the successful response to treatment.

New discoveries on the biology and detection of human chorionic gonadotropin

Reproductive Biology and Endocrinology, 2009
Human chorionic gonadotropin (hCG) is a glycoprotein hormone comprising 2 subunits, alpha and beta joined non covalently. While similar in structure to luteinizing hormone (LH), hCG exists in multiple hormonal and non-endocrine agents, rather than as a ...
