Abstract Objectives: To compare the effectiveness of two rapid urine tests fibrinogen / fibrin degradation products FDP (Aura Tek FDP, PerImmune Inc., Rockville, Maryland, USA) and bladder tumor antigen BTA (Bard BTA, Bard Canada Inc., Mississauga, Ontario, Canada) to urinary cytology in establishing the diagnosis of transitional cell carcinoma (TCC) in patients with suspected upper tract malignancy.
Materials and methods: In a prospective study, urine samples were collected from 29 patients with abnormalities of the upper tracts highly suspicious for malignancy. Sensitivity and specificity of the BTA and FDP tests were determined and compared to those of cytology.… More >

Abstract Spermatogenesis, with emphasis on spermiogenesis, is described for the lizard, Tropidurus itambere, using light microscopy, phase contrast and epifluorescence, as well as scanning and transmission electron microscopy. Cellular differentiation involves events of chromatin condensation, nuclear elongation and the formation of structural complexes, such as the acrosomal and axonemal ones. Other new characteristics, exclusive for this species, include various aspects of the subacrosomal granule, the insertion of the proacrosomal vesicle and the development of these structures to participate in the acrosomal complex. Radial projections occur just above the nuclear shoulders, which have been recognized already from the More >

Abstract We report a 55 year old man complaining of painless left testicular swelling that developed over 2 months. The imaging studies revealed an epididymal mass separate from the testicle. The patient underwent left radical orchiectomy. The histopathological examination of the orchiectomy specimen revealed poorly differentiated signet cell metastatic adenocarcinoma. More >

Abstract Ciprofloxacin (CFX) is an effective and relatively safe antimicrobial used in a variety of human infections. However, adverse drug reactions and positive results in genotoxic tests are reported.
In order to understand the possible pathophysiological mechanisms of the toxic effects informed for CFX, lipid hydroperoxides (LOOH) -oxidative mediators of peroxidation- were quantified in liver and kidney of mice, after 15 to 360 minutes of the ciprofloxacin administration at doses of 10 mg/ Kg or 100 mg/ Kg by ip route. The peroxidation in the lipid fraction was evaluated by measuring the amount of hydroperoxides through… More >

Abstract The ultrastructure of the ovariole sheath along the Diatraea saccharalis ovariole was studied by scanning and transmission electron microscopy. Each ovariole is surrounded by an epithelial sheath, a tunica propria and scattered lumen cells. These three components of the ovariole sheath show different ultrastructural features along the ovariole, in the germarium or in the vitellarium; these differences are more evident in the epithelial sheath cells. The epithelial sheath is composed by two layers of cells, the external one running longitudinally and the internal one running circularly in the ovariole. These cells, in vitellarium, present cytoplasmic bundles More >
