Lifestyle Management in Menopause: A Systematic Review of Women With Premature Ovarian Insufficiency

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Premature ovarian insufficiency (POI), the loss of ovarian function before age 40, increases the risk of cardiovascular disease, low bone mineral density, dementia and psychological distress. Lifestyle interventions reduce chronic disease risk in other populations and, with hormone therapy, may improve health outcomes in POI.

Calcitonin Directly Inhibits Luteinizing Hormone-Stimulated Progesterone Production in Granulosa Cells of the Largest Follicle of Hen

The Journal of Poultry Science, 2010
The present study was performed to demonstrate the presence of receptors for avian calcitonin (cCT) in ovarian granulosa cells of the largest follicle of laying hens and to determine the effect of cCT on LH-stimulated P4 production.

High rate of aneuploidy in luteinized granulosa cells obtained from follicular fluid in women who underwent controlled ovarian hyperstimulation

, 2005
We performed a prospective study to detect the cell cycle changes in luteinized granulosa cells in patients undergoing controlled ovarian stimulation with GnRH analog and gonadotropin therapy. Aneuploid DNA content was observed in 37 of 70 women (52.9%),

Wt1 Is Required for the Regression of Müllerian Ducts in Male Mice by Inducing Wif1 and Osx Expression

Cell Proliferation, EarlyView.
Wt1 expressed in the MD mesenchyme promotes MD regression by inducing Wif1 and Osx transcription. In male mice, mesenchyme‐specific inactivation of Wt1 results in MD retention. ABSTRACT In mammals, Müllerian ducts (MDs) are the precursors of the female reproductive tract which regress in males during embryonic development.

Retinoic acid enhances ovarian steroidogenesis by regulating granulosa cell proliferation and MESP2/STAR/CYP11A1 pathway

Journal of Advanced Research
Introduction: Ovarian steroidogenesis not only affects the embryonic development and pregnancy outcome, but also associates with many diseases in mammals and women. Exploring the nutrients and mechanisms influencing ovarian steroidogenesis is critical to

Fine Particulate Matter (PM) Effects on Swine Granulosa and Ovarian Endothelial Cells

We studied fine particulate matter (PM) effects on porcine granulosa, a model of endocrine reproductive cells, and on ovarian endothelial cells. PM produced a significant decrease (p p 2−) production by granulosa was reduced (p p p p p p p p p p < 0.05 ...

No Female Germline Stem Cells Were Identified by Advanced Dual Recombinase‐Based Lineage Tracing System

Cell Proliferation, EarlyView.
Schematic summary of the dual‐recombinase lineage tracing strategies to determine whether female germline stem cells (fGSCs) exist and sustain the ovarian follicle pool in adult female mice. Our study concluded that no fGSCs exist and contribute to oocyte regeneration in adult female mice with different tracing systems. ABSTRACT Whether female germline

Clinical and surgical findings in a mare with unilateral ovarian fibroleiomyoma and adhesions

Equine Veterinary Education, EarlyView.
Summary This case report describes the clinical presentation, ultrasonographic findings, surgical management and outcome of a 7‐year‐old Warmblood mare presented for recurrent colic, weight loss and poor performance. Rectal palpation identified a firm mass in the left caudal abdomen, which appeared on ultrasonography as a large, fluid‐filled, cyst‐like

Ovarian Thecal Cells Produce Transforming Growth Factor-β Which Can Regulate Granulosa Cell Growth

, 1987
Ovarian thecal cells in culture were found to synthesize and secrete transforming growth factor-β (TGFβ). A component in thecal cell-conditioned medium was immunologically similar to TGFβ, as assessed with a RIA, and inhibited specific binding of TGFβ to
