Triploidia fetal associada à diminuição da subunidade beta e do estriol não-conjugado no soro materno Fetal triploidy associated with low levels of unconjugated estriol and beta-subunit in maternal serum

Revista Brasileira de Ginecologia e Obstetrícia, 1999
Relatamos um caso de triploidia fetal não-molar detectada na 20ª semana gestacional por cordocentese realizada em razão de estudo ultra-sonográfico que revelou retardo do crescimento intra-uterino e grave oligoidrâmnio.

SDS-PAGE Electrophoretic Property of Human Chorionic Gonadotropin (hCG) and its β-subunit [PDF]

International Journal of Biological Sciences, 2005
The microheterogeneity property of hCG with regards to its sialic acid contents resulted in variable mobility of the glycoprotein in SDS-PAGE. The intact hCG molecule is composed of two dissimilar subunits, namely alpha- and beta-subunits. The identification of hCG bands in SDS-PAGE was accomplished by the immunoblotting experiment, whereby the ...

Clustering Longitudinal Data: A Review of Methods and Software Packages

International Statistical Review, Volume 93, Issue 3, Page 425-458, December 2025.
Summary Clustering of longitudinal data is becoming increasingly popular in many fields such as social sciences, business, environmental science, medicine and healthcare. However, it is often challenging due to the complex nature of the data, such as dependencies between observations collected over time, missingness, sparsity and non‐linearity, making ...

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]

, 2015
cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

BHLHE40 Cooperates with GATA2/3 to Control Human Syncytiotrophoblast Lineage Differentiation

Advanced Science, Volume 12, Issue 44, November 27, 2025.
BHLHE40 interacts directly with GATA2 and GATA3 and co‐occupies genomic loci critical for STB differentiation and function. BHLHE40 also affects GATA2/3 binding at enhancer and promoter regions. Moreover, BHLHE40 is potentially involved in genome‐wide remodeling of H3K4me3 and H3K27ac chromatin landscapes through GATA2/3 recruitment, activating ...

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.

Use of the Abbott i‐STAT®1 point of care device for hCG quantification in early pregnancy

International Journal of Gynecology &Obstetrics, Volume 171, Issue 2, Page 736-742, November 2025.
Abstract Objectives To evaluate the use of the Abbott i‐STAT®1 point‐of‐care‐test (POCT) device for measurement of human chorionic gonadotropin (hCG) to support the management of early pregnancy complications in a remote early pregnancy unit (EPU). Methods Women attending the EPU who required an hCG blood test were invited to take part in the study ...

Metabolic and Inflammatory Stimuli Impact Vascular Circulation and Cell Proliferation Processes in the Amygdala

Genes, Brain and Behavior, Volume 24, Issue 5, October 2025.
Sex‐specific differential expression of the genes in the synaptic vesicle cycle pathway of the amygdala in response to stimuli. In the pathway network depiction, the edges connecting the nodes (genes) represent known molecular interactions. More intense red and blue hues indicate gene under‐expression and over‐expression in response to fasting relative
