BACKGROUND: Social Egg Freezing (SEF), often promoted in Western contexts as a means to enhance reproductive autonomy, has seen varied uptake in countries with wider gender disparities. In such settings, where reproductive decisions are sha…

Background/Objectives: Placental abruption has a high risk of recurrence, but the timing of recurrence relative to the previous episode remains unclear. This study described the gestational-age distribution of recurrent placental abruption …

BACKGROUND: Systemic artery-to-pulmonary artery fistula (SAPAF) is a rare vascular anomaly, and involvement of the inferior phrenic artery is particularly uncommon. Acquired SAPAF may occur as a late postoperative complication; however, dia…

BACKGROUNDS: Acute pancreatitis (AP) is a common inflammatory disease of the pancreas, characterized by complex pathogenesis and limited specific treatment options. The selective autophagy adapter protein p62/sequestosome1 emerged as a key …

BACKGROUND: Uterine adenomyosis is a benign disease, common among women in their 40 and 50 s, characterised by ectopic endometrial tissue in the uterine myometrial layer. Adenomyosis causes infertility and has a negative effect on the outco…

A previous study by our group reported that removing a larger number of lymph nodes in patients with stage I ovarian clear cell carcinoma (OCCC) improved progression-free survival (PFS). The present study investigated whether clinical condi…

PURPOSE: Programmed cell death 1 (PD1) and PD ligand 1 (PDL1) are speculated to have an important role in maintaining a normal pregnancy and there are also a few reports of an association between the single-nucleotide polymorphisms (SNPs) o…

The aims of our study were to describe our case series of three urethral diverticulum carcinomas (UDC) in women and to review the literature on UDC in females to determine patient characteristics, presenting symptoms and outcomes along with…

Lipolysis-stimulated lipoprotein receptor (LSR) is a unique molecule of tricellular contacts of normal and cancer cells. We investigated how the loss of LSR induced cell migration, invasion and proliferation in endometrial cancer cell line …

Lipolysis-stimulated lipoprotein receptor (LSR) has been identified as a novel molecular constituent of tricellular contacts that have a barrier function for the cellular sheet. LSR recruits tricellulin (TRIC), which is the first molecular …

OBJECTIVE: Endometrial cancer often coexists with uterine adenomyosis. However, little is known about the clinical characteristics of these cases. Thus, cases of endometrial cancer occurring with and without uterine adenomyosis were compare…

BACKGROUND: Previous studies have found that the decision-making process for stored unused frozen embryos involves much emotional burden influenced by socio-cultural factors. This study aims to ascertain how Japanese patients make a decisio…

Gonadotropin-releasing hormone (GnRH) analogue has beneficial effects on the size and symptoms of endometriosis and uterine leiomyomas as a result of suppressing ovarian steroidogenesis. GnRH analogues are also the preferred treatment for a…

Adenocarcinomas arising from adenomyosis uteri are rare. This study reports four such cases and characterizes them clinically and microscopically. In all four patients, the endometrial cytology was negative, and MR imaging and ultrasound so…

We describe a 47-year-old woman with severe aplastic anemia with genital bleeding who developed acute severe hepatitis after the administration of danazol while she was receiving cyclosporin. She had been diagnosed with severe aplastic anem…
