Value of endometrial biopsy in patients with hysteroscopically atrophic endometrium in patients with postmenopausal bleeding.
Arch Gynecol Obstet
January 2025
Derby Gynaecological Cancer Centre, Department of Gynaecology, University Hospitals of Derby and Burton NHS Foundation Trust (UHDB), Royal Derby Hospital, Uttoxeter Road, Derby, DE22 3NE, UK.
Purpose: To determine the rate of precancer and cancer in women presenting with PMB who have a visually atrophic endometrium at hysteroscopy and assess the value of endometrial biopsy in this situation and the adequacy of the samples obtained.
Methods: Retrospective reviews of all patients with a visually atrophic endometrium at hysteroscopy who had presented with PMB and had an ET > / = 4 mm or ET < 4 mm with focal changes or irregular features between 2013 and 2024 at University Hospitals of Derby and Burton were included (n = 1096). Patients who had previously had cancer or precancer or had unclear hysteroscopy findings were excluded.
Rapamycin inhibits tamoxifen-induced endometrial proliferation in vitro as a pilot approach for endometrial protection in breast cancer.

Department of Obstetrics and Gynecology, Shiga University of Medical Science, 520-2192/Seta Tsukinowa-cho, Otsu, Shiga, Japan.
Tamoxifen, a common adjuvant therapy for hormone receptor-positive breast cancer, is associated with an increased risk of endometrial pathologies, such as hyperplasia, polyps, and carcinoma. This study investigates rapamycin, an mTOR inhibitor, as a potential novel strategy for preventing tamoxifen-induced endometrial proliferation. This in vitro study utilised endometrial stromal cells isolated from infertile women.

Background: Saidi sheep are one of the most important farm animals in Upper Egypt, particularly in the Assiut governorate. Since they can provide meat, milk, fiber, and skins from low-quality roughages, sheep are among the most economically valuable animals bred for food in Egypt. Regarding breeding, relatively little is known about the Saidi breed.

- PFOS is a chemical frequently used in industries that can enter the environment and is resistant to breakdown, leading to health concerns.
- Recent studies show a link between PFOS exposure in humans and various diseases, highlighting its impact on human health.
- Research indicates that PFOS negatively affects endometrial cell function and morphology, potentially leading to issues with embryo implantation due to mitochondrial damage and alterations in key protein expression.
Dead or Alive: Exploratory Analysis of Selected Apoptosis- and Autophagy-Related Proteins in Human Endometrial Stromal Cells of Fertile Females and Their Potential Role During Embryo Implantation.
Int J Mol Sci

Department of OB/GYN and REI (UniKiD), Medical Faculty and University Hospital Duesseldorf, Heinrich Heine University Duesseldorf, 40255 Duesseldorf, Germany.
To date, very little is known about how apoptosis and autophagy affect human endometrial stromal cells (ESCs), particularly how these processes might determine the depth of implantation in humans. Before investigating how apoptosis and autophagy might modulate the implantation process in an infertile population, it is necessary to clarify how these processes are regulated in healthy individuals. This study examined the protein expression related to apoptosis and autophagy in primary ESCs from fertile women, particularly in the context of decidualization and embryo contact, using Western blot analysis.
