The 1000 subjects randomly selected were evaluated for the presence of the vomeronasal organ (VNO). The results of the present investigation indicated the presence of the VNO in almost every subject studied. The implications of the presence of the VNO and its clinical significance during nasal operations are considered.
During neoplastic growth and metastasis, the immune system responds to the tumor by developing both cellular and humoral immune responses. In spite of this active response, tumor cells escape immune surveillance. We previously showed that FasL expression by breast tumor plays a central role in the induction of apoptosis of infiltrating Fas-immune cells(More)
We have developed a coculture system with autologous human endometrial epithelial cells (AEEC) that retained many features of human endometrial epithelium. Implantation failure (IF; >3 previous cycles failed with 3-4 good quality embryos transferred) is a distressing condition in which 2-day embryo transfer repetition is the routine option. The objective of(More)
CONTEXT Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of treatment with fertility drugs. It is characterized by increased vascular permeability and simultaneous overexpression of vascular endothelial growth factor (VEGF) in ovarian cells. OBJECTIVE We tested the hypothesis that the endothelium and endothelial cell-to-cell(More)
BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of ovarian stimulation, and the pathophysiological mechanisms that trigger the syndrome remain unknown. HCG increases serum vascular endothelial growth factor (VEGF) concentrations, and VEGF modulates transendothelial permeability via endothelial adherens junctions, a(More)
BACKGROUND Adenomyosis is linked to infertility, but the mechanisms behind this relationship are not clearly established. Similarly, the impact of adenomyosis on ART outcome is not fully understood. Our main objective was to use ultrasound imaging to investigate adenomyosis prevalence and severity in a population of infertile women, as well as specifically(More)
A rapid development and application of assisted reproductive technologies (ARTs) and ovulation-induction drugs may lead to ovarian hyper stimulation syndrome (OHSS). Young age, low body mass index (BMI), polycystic ovarian syndrome (PCOS), previous OHSS, high follicle count, and elevated serum estradiol (E2) are the certain factors that predispose women to(More)
In India, a practice of "Batch in vitro fertilization (IVF)" has evolved in many infertility centers in an effort to align infertility management with logistics. A "Batch IVF" is an approach where the menstrual cycles of multiple women are programmed, such that they can undergo all the processes; from stimulation until embryo transfer about the same time.(More)

BACKGROUND Both oral contraceptive pills (OCPs) and estradiol (E2) valerate have been used to schedule gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization (IVF) cycles and, consequently, laboratory activities. However, there are no studies comparing treatment outcomes directly between these two pretreatment methods. This randomized(More)
