Abstract OBJECTIVE: To assess the ovarian content of selectable (2-5 mm) follicles using three-dimensional ultrasonography in low responders to ovarian stimulation for IVF. DESIGN: Prospective case-control study. SETTING: IVF program at the Instituto Valenciano de Infertilidad. PATIENT(S): Ten low responders < or =35 years of age with normal basal serum FSH and eight control patients […]
Relationship of ovarian stromal volume to serum androgen concentrations
Abstract The aim of this study was to investigate of the relationship of ovarian stromal volume, measured using three-dimensional ultrasound, to serum androgen concentrations in patients with polycystic ovaries. Serum gonadotrophin, oestradiol and androgen concentrations and ovarian volume measurements were obtained in the early follicular phase from 100 women undergoing assisted conception treatment cycles. Group […]
The role of three-dimensional ultrasonographic images in ovarian measurement
The most common type of risk that occurs during the risk-free arbitrage trading is Execution risk. Multi-tasking is not something which is comfortable to all of us and we naturally tend to leave the most of the activities midway or fail in them. This is what happens when you take arbitrage too casually and engage […]
Tissue engineering of a bioartificial renal tubule
Abstract Development of a bioartificial renal tubule with a confluent monolayer of renal epithelial cells supported on a permeable synthetic surface may be the first step to further optimization of renal substitution therapy currently used with hemodialysis or hemofiltration. Madin-Darby canine kidney cells, a permanent renal epithelial cell line, were seeded into the lumen of […]
The shape of the endometrium evaluated with three-dimensional ultrasound
Abstract Woman, as a recipient of a collective effort from the legislatures, may be most thankful for perhaps a micro effect which started as small but have grown its spread to far and deep into the most vulnerable society. The biggest achievement of microfinance is touted as women empowerment and is true also to a […]
High frequency of well-defined Y-chromosome deletions
Abstract Idiopathic Sertoli cell-only syndrome (SCOS) is characterized by azoospermia, small testes, absence of germ cells in the testes, elevated follicle stimulating hormone and normal testosterone concentrations. The Y-chromosome is involved in the regulation of spermatogenesis and in the pathogenesis of a fraction of idiopathic male infertility. An azoospermia factor (AZF) is present on the […]
Ultrasound screening for congenital uterine anomalies
Abstract The aim of this study was to investigate the prevalence of congenital uterine anomalies in 1046 women attending gynaecological ultrasound clinics for a variety of indications. Using three-dimensional ultrasound, anomalies were found in 55 women (5.4%), including 32 (3.1%) with an arcuate uterus and 23 (2.3%) with major anomalies. You can trade on the […]
Detection of congenital müllerian duct anomalies
Abstract PURPOSE: The purpose of this study was to assess the value of 3-dimensional sonography in the diagnosis of congenital müllerian duct anomalies, which cause infertility, preterm labor, and first trimester abortion. METHODS: A prospective study was undertaken in which 40 patients with histories of repeated spontaneous abortions or infertility were first examined using conventional […]
Combined cytogenetic and Y chromosome microdeletion screening
The initial step in stock trading is thought to be the toughest one, but there are equally compelling challenges in the trading field to be overcome in order to achieve the success that a trading market beams of. Rags to riches stories have always propelled the popularity of stock markets, traders, and investment brokers. Every […]
Reconstitution of human urothelium from monolayer cultures
Abstract PURPOSE: We established a 3-dimensional organ culture model of urinary tract tissue in which to study the effects of seeding cultured urothelial cells onto de-epithelialized urothelial stroma. MATERIALS AND METHODS: Normal human urinary tract tissues were placed in organ culture or used to establish urothelial cell cultures. At passage 2 cell cultures were harvested […]
