The fibrosis mechanism in endometriosis is not elucidated. We investigated the role of eosinophil in fibrosis of endometriosis. The endometriotic stromal cells (ESCs) and endometrial epithelial cells (EECs) were subjected to in vitro experi…

INTRODUCTION: Robotic surgery is being rapidly implemented globally, and new robotic surgery techniques are being developed. The da Vinci SP surgical system, a new robotic surgery system using a single-port approach, was introduced for the …

OBJECTIVES: Robot-assisted surgery has become popular in Japan, especially with the introduction of the da Vinci SP® surgical system, which is a significant advancement in minimally invasive surgery. The da Vinci SP® surgical system, which …

AIM: Curative resection and organ preservation are important to manage rectal gastrointestinal stromal tumors; however, postoperative quality of life, including urinary function, remains a concern. Our prior findings suggest a high incidenc…

We report a case where a spontaneous pregnancy and delivery of a live baby were achieved after laparoscopic repair combined with hysteroscopy of the cesarean section scar secondary to treatment for a prior cesarian section scar pregnancy. […

Aging drives excessive ovarian oxidative stress (OS), impairing fertility and affecting granulosa cells (GCs), which are involved in folliculogenesis. This study aims to clarify the relationship between OS and autophagy in GCs and to identi…

Autophagy is a fundamental process involved in regulating cellular homeostasis. Autophagy has been classically discovered as a cellular process that degrades cytoplasmic components non-selectively to produce energy. Over the past few decade…

PROPOSE: Does an annotation-free embryo scoring system based on deep learning and time-lapse sequence images correlate with live birth (LB) and neonatal outcomes? METHODS: Patients who underwent SVBT cycles (3010 cycles, mean age: 39.3 ± 4…

For preparing the optimal condition in transcervical resection (TCR) surgery, gonadotropin-releasing hormone (GnRH) agonist has been utilized. Recently, an oral GnRH antagonist (relugolix) is available and acts directly on GnRH receptor, av…

BACKGROUND: The KIDScore™ Day 5 (KS-D5) model, version 3, is a general morphokinetic prediction model (Vitrolife, Sweden) for fetal heartbeat prediction after embryo transfer that was developed based on a large data set that included implan…

In endometriosis, M2 macrophages (MΦ) are dominant and promote the development of endometriosis lesions. However, the factor(s) which induces M2 MΦ are unknown. In the present study, we focused on interleukin (IL)-33, known as an alarmin an…

Relaxin (RLX)-2, produced by the corpus luteum and placenta, is known to be potentially effective in fibrotic diseases of the heart, lungs, kidneys, and bladder; however, its effectiveness in endometriosis has not yet been investigated. In …

(1) Background: Previous reports have indicated that cancers of the stomach, lung, and pancreas can be detected by dog sniffing, but results have been varied. Here, a highly trained dog was used to determine whether urine from patients with…

OBJECTS: There is growing evidence that sphingosine 1-phosphate (S1P) is involved in inflammatory diseases. As endometriosis is known as an inflammatory disease, we investigated the role of S1P system in the development of endometriosis. M…

OBJECTIVE: To investigate the efficacy and safety of ethinylestradiol 20 μg/drospirenone 3 mg in a flexible extended regimen (FlexibleMIB) compared with placebo to treat endometriosis-associated pelvic pain (EAPP). DESIGN: A phase 3, rando…

A 25-year-old female mandrill (Mandrillus sphinx) died after exhibiting weakness and recumbency with serosanguineous ascites. Gross findings included haemoperitoneum and multifocal to diffuse serosal thickening with petechiae and ecchymoses…

The nuclear factor kappaB (NF-kappaB) is a ubiquitously expressed transcription factor playing vital roles in innate immunity and other processes involving cellular survival, proliferation, and differentiation. This review highlights the im…

The identification of a novel helper T (Th)-cell subset, the IL-17-producing Th (Th17) cells, has provided new insight into our understanding of the molecular mechanisms of reproduction. IL-17 has an important role in induction of the prote…

The sensitivity and specificity of CA125, as a sole serum marker of endometriosis, are not high enough for routine clinical assessment. To explore new markers for the diagnosis of endometriosis, serum autoantibodies in endometriotic patient…

Apoptosis is a distinctive form of programmed cell death resulting in the efficient elimination of cells without eliciting an inflammatory response. Endometriosis is characterized by the presence of endometrial cells with capacity to avoid …

BACKGROUND: We aimed to establish an endometrial autograft model in rats that would allow for repetitive in vivo analyses of angiogenesis. Dienogest (DNG) is an orally active progestin used for the treatment of endometriosis. We investigate…

OBJECTIVE: To establish a novel serum marker for endometriosis, serum autoantibodies (autoAbs) were investigated using a proteomic approach. DESIGN: Retrospective study. SETTING: Departments of Molecular Pathology and Obstetrics and Gynec…

BACKGROUND: The human endometrium undergoes cyclical regeneration throughout a woman's reproductive life. Ectopic implantation of endometrial cells through retrograde menstruation gives rise to endometriotic lesions which affect approximate…

Diagnosis of endometriosis needs invasive maneuvers. New serum marker that possesses both high sensitivity and high specificity has long been desired. To establish novel serum marker for endometriosis, serum autoantibodies (autoAbs) were in…

PURPOSE: To evaluate the cystectomy-induced damage on the follicular growth and ovulation of an affected ovary during natural cycles. METHODS: Twenty-eight infertile patients with unilateral ovarian endometriomas who underwent laparoscopic…
