Subclinical cardiac alterations and cardiometabolic profile in adolescents with newly diagnosed polycystic ovary syndrome: A cross‐sectional comparative echocardiographic study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective While cardiometabolic comorbidities have been well established in adults with polycystic ovary syndrome (PCOS), it remains unclear whether the early signs of cardiovascular morbidity emerge during adolescence. This study aimed to investigate whether metabolic and cardiovascular alterations begin in adolescents with PCOS.

Identification of DNA Sequences that are Necessary and Sufficient for Activin Induction of Ovine Follicle Stimulating Hormone Beta-Subunit.

, 2009
Follicle stimulating hormone (FSH) is an alpha/beta heterodimer central to vertebrate reproduction, and its synthesis depends on expression of its beta-subunit (FSHB). Activin is the primary inducer of FSHB, and previous work from this laboratory showed

Advanced glycation end products interfere in luteinizing hormone and follicle stimulating hormone signaling in human granulosa KGN cells

, 2017
Advanced glycation end products accumulate in the ovarian granulosa-cell layer of women with polycystic ovarian syndrome. Taken that the MAPK/ERK-pathway is a key regulator of oocyte maturation and function, consisting the main pathway used by the ...

Surgically confirmed severe endometriosis is associated with lower risk of steatotic liver disease: Evidence of estrogen‐linked hepatic–reproductive crosstalk

International Journal of Gynecology &Obstetrics, EarlyView.
Severe surgically confirmed endometriosis was associated with a lower prevalence of steatotic liver disease than non‐severe disease. Higher estradiol levels may partly explain this inverse hepatic–reproductive association, supporting integrated gynecologic and hepatologic risk assessment.
