fallopian tube

Shang Wang, Irina V Larina
The oviduct (or fallopian tube) serves as the site where a number of major reproductive events occur for the start of a new life in mammals. Understanding the oviduct physiology is essential to uncover hidden mechanisms of the human reproduction and its disorders, yet the current analysis of the oviduct that is largely limited to in vitro imaging is a significant technical hurdle. To overcome this barrier, we have recently developed in vivo approaches based on optical coherence tomography for structural and functional imaging of the mouse oviduct...

Ectopic pregnancy is an extrauterine pregnancy, and 98% of which occur in the fallopian tube. The incidence of twin tubal pregnancy is rare but is increasing due to assisted reproductive technology. Spontaneous unilateral twin tubal pregnancy is extremely rare, and only a small number of case reports have been made. We herein report a rare case of spontaneous unilateral twin tubal pregnancy with both fetuses presenting with heart activities and a literature review. Right salpingectomy was performed in this case...

Fallopian tube secretory epithelial cells (FTSECs) have been suggested to be the source of high-grade serous ovarian carcinoma (HGSOC). Although several genetic alterations are known to be involved in HGSOC development, the minimal requirements remain unclear. We aimed to identify oncogenic mutations indispensable for HGSOC development in a stepwise model, using immortalized FTSECs. FTSECs were isolated from clinical samples and immortalized by overexpression of cyclin D1, CDK4R24C , and hTERT . Oncogenic mutations in the p53, c-Myc, and RAS/PI3K pathways were mimicked by lentiviral transduction...

It has been realised that rhythmic peristalsis of the ostia and tubes can be observed during hysteroscopy. The aim of this study was to examine the presence of tubal peristaltic dysfunction in unexplained infertility (UI). Hysteroscopy was performed in 35 women with UI and in 37 healthy fertile women. Bilateral tubal peristalses were assessed hysteroscopically by the observation of methylene blue injection and its transport to the Fallopian tubes. Tubal patency was evaluated with laparoscopic chromopertubation...

The present study aimed to determine the amount of fluid medium passing through the Fallopian tubes into the peritoneal cavity during a hysteroscopy. This was done to understand the pathophysiology of complications related to the hysteroscopy. Conducted in a general hospital setting, the study examined the fluid inflow-outflow during a hysteroscopy both in pre- and post-menopausal women. A hysteroscopy was performed vaginoscopically for both diagnostic and therapeutic procedures. The study involved 117 patients...

OBJECTIVE: Salpingectomy is the surgical removal of a fallopian tube, often as a result of tubal pregnancy. Little is known about the role of self-efficacy, health consciousness and health locus of control in health expectation and health anxiety among post-salpingectomy patients. BACKGROUND: An ectopic pregnancy and subsequent salpingectomy could present significant life crises for any woman with far-reaching implications. METHODS: Sixty purposively selected post-salpingectomy women (gravida 0-6; parity 0-4; mean age 34 ± 4...

Breast cancer is the most prevalent cancer in the United States. With an increasing rate of survivorship and extended life span for patients with metastatic disease, the demand for palliative care is increasing. Although uncommon, metastases to gynaecologic organs have been reported and are often present with post-menopausal bleeding. Post-menopausal bleeding can become clinically significant and have a detrimental effect on quality of life. We report the case of a 70-year-old woman with symptomatic vaginal bleeding caused by breast cancer metastatic to her uterus, cervix, fallopian tubes and ovaries...

The sterile insect technique (SIT) may reduce pest populations by allowing sufficient amount of irradiation-induced sterile males to mate with wild females whilst maintaining mating ability comparable to wild males. Although the SIT methods are well understood, the optimal sterilizing dose and processing development stage for application vary among species. To ensure effective pest control programs, effects of irradiation on physiology, behavior, and gene function in the target species should be defined, however, little is known about irradiation effects in Bactrocera tau ...

Globally, an estimated 131 million new cases of chlamydial infection occur annually. Chlamydia trachomatis infection can cause permanent damage to the fallopian tubes in woman, resulting in infertility and a risk of ectopic pregnancy. There is a great need for a vaccine against Chlamydia trachomatis and as a result there is a need for assays to evaluate functional immune responses for use in future clinical trials and epidemiological studies. Antibodies play a crucial role in the defense against infection and can be protective by several functions, including phagocytosis and neutralization...

OBJECTIVES: In women receiving sterilization, the removal of the entire fallopian tube, a procedure referred to as a risk-reducing salpingectomy (RRS), reduces subsequent ovarian cancer risk compared with standard tubal sterilization procedures. There are limited data on which surgical procedure women will choose when educated about the benefits of an RRS. Our objective was to study the proportion of women desiring sterilization that would choose an RRS. METHODS: This cohort study included women 30 years of age and older with a living biological child who requested laparoscopic sterilization at a tertiary academic hospital...

Postablation tubal sterilization syndrome (PATSS) is an uncommon complication of endometrial ablation in patients with antecedent tubal ligation characterized by cyclic pelvic pain. Recurrent tubal distention resulting from retrograde menstruation into occluded proximal fallopian tube segments by residual/regenerated cornual endometrial tissue is postulated to be the cause. Reports of PATSS have largely focused on the clinicoradiologic and operative findings. Detailed descriptions of the gross pathologic findings of PATSS are sparse and rarer still are examples in which the histologic manifestations are discussed...
