BACKGROUND Ultrasonography has been extensively used in women suspected of having a gynecological malignancy. The aim of this study is to evaluate the efficacy of 3D ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding. METHODS This cross-sectional study included 78 premenopausal women with abnormal...

breakthrough bleeding (btb) is the cause of 50% of discontinuations of use by long-acting progestogen-only contraceptive users. btb appears to be associated with capillaries of abnormal morphology and fragility. disturbances in vessels integrity, intercellular junctions or alteration of the basement membrane (bm) composition has been proposed to contribute toward the fragility of these capillar...

The present study focused on the early events of vascularization of intraocular cerebral transplants. Telencephalic pieces of rat embryos (E15) were transplanted into the anterior eye chamber of adult rats in deep ketamine-xylazine narcosis. At 3-, 4-, 5-, 6-, or 7-day postoperative survival periods, the rats were perfused and the transplants, with their iridic beds, were processed into serial,...

PURPOSE To report deep corneal vascularization noted 3 years after intrastromal corneal ringsegments (Intacs) implantation for the treatment of keratoconus. METHODS A 33-year-old male keratoconus patient intolerant to rigid gas permeable contact lens in the right eye underwent Intacs implantation. At 2 years postoperatively, slit-lamp examination of the right eye revealed superficial corneal ...

PURPOSE To study the diagnostic accuracies of serum human epididymis protein 4 (HE-4) levels, virtual organ computer-aided analysis (VOCAL) parameters and endometrial volume in endometrial cancer cases. MATERIALS AND METHODS One hundred and seven patients (37 with endometrial cancer and 70 with benign endometrial pathology) were included in this study. VOCAL parameters and serum HE-4 levels w...

Vascularization is crucial for tumor growth and metastasis. Angiogenesis and vasculogenesis are widely accepted processes of tumor vascularization, particularly for endothelium-dependent vessels. In both these processes, the tumor vascular endothelial cells are derived from the host cells, including cells in normal tissues around the tumor or endothelial progenitor cells. In addition, the mosai...

Normal chorionic villous vascularization is essential for the undisturbed development of pregnancy. Defective vasculogenesis may play a role in pathological pregnancy. To assess pathological chorionic villous vascularization, normal vascularization has to be defined first. Few data are available on this topic. The aim of this study was therefore to investigate normal chorionic villous vasculari...

A 65-year-old male presented to us with symptoms of severe pain in right eye with loss of vision for 1 week. He had undergone a manual small incision cataract surgery elsewhere 2 weeks back. 48–72 hours post-surgery, his vision started decreasing and he presented to us in a state shown in the figure 1. On examination, a provisional diagnosis of post-operative endophthalmitis was made. The anter...

BACKGROUND To investigate the effect of fertility stress on endometrial and subendometrial blood flow among infertile women. METHODS This case-control study was conducted in The First Affiliated Hospital of Zhengzhou University. The fertility problem inventory (FPI) was adopted to evaluate fertility stress. Three-dimensional power Doppler ultrasonography (3D PD-US) was performed during the pr...
