The present work applies Gabor filters bank for texture analysis of skin lesions images, obtained by ultrasound biomicroscopy. The regions affected by the lesions were differentiated from surrounding tissue in all the analyzed cases; however the accuracy of the traced borders showed some limitations in part of the images. Future steps are being contemplated, attempting to enhance the technique ...

BACKGROUND & OBJECTIVES This study was carried out to determine the appearance of various cystic ovarian lesions on transvaginal real-time ultrasonographic elastography and to investigate its potential in the differential diagnosis of cystic ovarian lesions. METHODS Twenty six women (age range, 27-71 yr; mean age 42 ± 16 yr) with cystic ovarian masses underwent transvaginal B-mode and Doppler...

The National Toxicology Program's pathology database on 2-year carcinogenicity studies was reviewed for nonneoplastic ovarian disease. Ovaries from 39,941 female Fischer rats and 41,444 female B6C3F1 mice were examined. A variety of inflammatory, degenerative, vascular, and proliferative lesions were documented and are described. The most common ovarian lesions in rats were cysts (6%). The most...

The aim of the study was to determine optimal hydrolysis time for the Feulgen DNA staining of archival formalin fixed paraffin-embedded surgical samples, prepared as single cell suspensions for image cytometric measurements. The nuclear texture features along with the IOD (integrated optical density) of the tumor nuclei were analysed by an automated high resolution image cytometer as a function...

AIMS To find specific magnetic resonance imaging (MRI) features to differentiate metastatic ovarian tumors from primary epithelial ovarian cancers. METHODS Eleven cases with metastatic ovarian tumors and 26 cases with primary malignant epithelial ovarian cancers were retrospectively studied. All features such as patient characteristics, MRI findings and biomarkers were evaluated. The differen...

RATIONALE Advanced ovarian cancer is usually associated with intra-abdominal metastases and while it commonly spreads directly to the omentum, intestine, liver, or other organs, it can also metastasize through the lymphatic channels and the hematogenous pathway. With an increasing number of invasive operations being performed with chemoradiotherapy, the incidence of extra-abdominal metastases h...

Objective: To investigate the serum concentrations of copper (Cu), zinc (Zn) and copper/zinc ratio (Cu/Zn) in patients with ovarian cancer and benign ovarian lesions. Methodology: The study included 50 patients, with ovarian cancer (malignant group) and 50 patients with benign ovarian lesions (benign group). After overnight fasting, blood samples were collected. The concentrations of Cu and Zn ...
