Objective: To evaluate the effects of a P2X4 receptor (P2X4R)-specific antagonist on murine endometriotic-like lesions and human endometriotic stromal cells.

Design: Experimental study using an in vivo mouse endometriosis model and in vitro primary culture of human endometriotic stromal cells. NC-2600, an antagonist of the P2X4 ionotropic ATP receptor (P2X4R), was orally administered to the mice and cells.

Background: The da Vinci surgical systems (X and Xi) are fourth-generation systems marketed by Intuitive Inc. The X system is less expensive than the Xi system. This study compared the surgical outcomes of patients who underwent hysterectomy using the X and Xi systems.

Introduction: Hybrid total laparoscopic hysterectomy combines conventional laparoscopic surgery and robot-assisted devices: the camera and assistant forceps are operated by a robotic device, whereas the surgeon performs laparoscopic procedures, enabling surgery with a completely fixed field of view and significantly reducing errors in forceps grasping and needle misalignment. Here, we examined whether using two arms of the Hugo™ robot-assisted surgery system, one for the camera and one for the assistant, would improve surgical accuracy compared with conventional total laparoscopic hysterectomy.

Materials And Surgical Technique: The surgical system reduced surgeon errors in grasping the forceps during training and stabilized forceps operation.

This study describes the first reported treatment of a benign gynecological disease with the Medtronic's Hugo™ RAS System, the first robot-assisted device used in the field of gynecology in Japan. Patients who underwent robot-assisted total laparoscopic hysterectomy with the Hugo™ RAS System at the Tottori University Hospital between March 2023 and June 2023 were included in this study. In the first case, the patient was in her 40 s and had uterine fibroids.

Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) is a rare congenital anomaly of the genital tract. Since the secretion of sex hormones from the ovaries is preserved, leiomyomas and adenomyomas, which are estrogen-dependent diseases, may develop from the uterine remnant. In contrast, patients with myotonic dystrophy type 1 (DM1), the most common dystrophy in adults, are considered to be at high risk for benign tumors of the female reproductive system, such as uterine leiomyomas and ovarian cysts.

Objective: Adenomyosis is a gynecologic disorder characterized by symptoms of dysmenorrhea, abnormal uterine bleeding, and infertility. This study aimed to analyze the expression profiles of key inflammatory cytokines in the endometrium with adenomyosis and their involvement in epithelial-mesenchymal transition (EMT).

Study Design: Endometrial tissues collected from premenopausal women with (n = 3) or without (n = 3) adenomyosis during the secretory phase were subjected to DNA array analysis to examine inflammatory cytokines.

Purpose: To evaluate the efficacy of two progestins, levonorgestrel intrauterine system (LNG-IUS) and dienogest (DNG), for adenomyosis.

Methods: This study enrolled 157 women with adenomyosis, randomized to either LNG-IUS ( = 76) or DNG ( = 81) groups as a controlled clinical trial for 72 months. Participants were classified by three different localizations of adenomyosis: diffuse, focal, and extrinsic.

The aim of this study was to evaluate the signal intensity and signal attenuation of swept source optical coherence tomography (SS-OCT) for dental caries in relation to the variation of mineral density. SS-OCT observation was performed on the enamel and dentin artificial demineralization and on natural caries. The artificial caries model on enamel and dentin surfaces was created using biofilms incubated in an oral biofilm reactor.

Non-carious cervical lesions (NCCLs) involve various forms of tooth loss with different etiologies. This study aimed to utilize swept-source optical coherence tomography (SS-OCT) at 1300 nm wavelength range in vitro and in vivo to evaluate and clarify the mechanism of NCCLs. In the in vitro phase, a dentin attenuation coefficient (μt ) derived from the SS-OCT signal at NCCL was compared with mineral loss obtained from transverse microradiography (TMR) to determine a μt threshold to discriminate demineralization of cervical dentin in vivo.

This study aimed to investigate swept source optical coherence tomography (SS-OCT) as a detecting tool for occlusal caries in primary teeth. At the in vitro part of the study, 38 investigation sites of occlusal fissures (noncavitated and cavitated) were selected from 26 extracted primary teeth and inspected visually using conventional dental equipment by six examiners without any magnification. SS-OCT cross-sectional images at 1330-nm center wavelength were acquired on the same locations.

The aim of this study was to determine the diagnostic accuracy of swept-source optical coherent tomography (SS-OCT) in detecting and estimating the depth of proximal caries in posterior teeth in vivo. SS-OCT images and bitewing radiographs were obtained from 86 proximal surfaces of 53 patients. Six examiners scored the locations according to a caries lesion depth scale (0-4) using SS-OCT and the radiographs.
