Delayed Menopause Due to Ovarian Granulosa Cell Tumour

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2013
A patient presented to us with complaints of inability to attain menopause even at the age of 64. She has been having irregular cycles of bleeding for 5 days every 2-3 months from the age of 54. On evaluation, she was found to have endometrial hyperplasia and ultrasonography showed a homogenous solid ovarian mass of size of the 4 cm x 3.5 cm.

Cross‐Regulation Between DNA Methylation and Circadian Clock Reprogramming in Ovarian Cancer: Mechanistic Insights, Biomarker Potential, and Therapeutic Implications

International Journal of Cancer, Volume 160, Issue 1, Page 7-23, 1 January 2027.
ABSTRACT Early diagnosis remains challenging, recurrence rates remain high, and platinum resistance frequently develops in ovarian cancer (OC), collectively representing major barriers to long‐term patient survival. DNA methylation (DNAm), as a relatively stable yet dynamically modifiable epigenetic signature, can capture alterations in tumor states ...

Bisphenol Analog‐Induced Cytotoxicity: Unraveling Endoplasmic Reticulum (ER) Stress and Apoptotic Pathways

Journal of Applied Toxicology, Volume 46, Issue 12, Page 4782-4798, December 2026.
ABSTRACT Bisphenol A (BPA) is increasingly replaced by structural analogs, yet their safety remains insufficiently characterized. This study investigated whether BPA and selected analogs, bisphenol AF (BPAF), bisphenol AP (BPAP), bisphenol P (BPP), and bisphenol E (BPE), induce cytotoxicity through activation of endoplasmic reticulum (ER) stress and ...

Testicular torsion in foals and stallions

Equine Veterinary Education, Volume 38, Issue 12, Page 642-646, December 2026.
Summary Testicular torsion is a rare condition in horses characterised by a change in the position of the testis due to the testicular mesentery twisting around its own axis; it can occur both when the testis is still in the abdominal cavity and when it has descended into the scrotum.

RHOB Regulates Apoptosis of Granulosa Cells in Muscovy Duck Follicles via Mitochondrial Pathway

Animals
Muscovy ducks (Cairina moschata) exhibit strong nesting tendencies, which result in reduced egg-laying performance. The research team previously identified differential expression of the Ras homolog family member B (RHOB) gene in the ovaries of Muscovy ...

Ovarian pain in the mare: Clinical implications of mittelschmerz and oestrus‐related behavioural abnormalities

Equine Veterinary Education, Volume 38, Issue 12, Page 661-667, December 2026.
Summary Mittelschmerz is a well‐recognised benign peri‐ovulatory pain syndrome in women and, by physiological analogy, may also occur in mares. In equine practice, peri‐ovulatory ovarian pain has been associated with transient discomfort, colic‐like signs and behavioural changes, although its true clinical relevance remains poorly defined.

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

Advanced Science, Volume 13, Issue 61, 3 November 2026.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

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, Volume 175, Issue 2, Page 895-901, November 2026.
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.

Cycloastragenol Attenuates Cisplatin‐Induced Ovarian Toxicity in Rats: Associations With TERT Expression, Apoptotic Balance, and FOXO3a–mTOR‐Related Signaling

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 11, November 2026.
Cycloastragenol partially attenuated cisplatin‐induced ovarian toxicity and was associated with partial preservation of follicular morphology, improvement in apoptotic balance, and changes in FOXO3a–mTOR‐related markers and ovarian TERT expression. ABSTRACT Cisplatin (CIS)‐induced ovarian toxicity is characterized by follicular depletion, apoptosis ...
