OBJECTIVE To investigate if PSA adjusted to transition zone (PSA-TZ) can be considered as a predictor parameter of cancer with better specificity or not than PSA, PSA density (PSAD) or PSA free/total ratio. MATERIAL AND METHODS Data of 706 patients with sextant prostatic biopsies are analyzed in prospective way because of prostatic cancer suspicion. Range of PSA was between 4 to 20 ng/ml. Det...

With P-to-S converted waves recorded at seismic stations of the US Transportable Array we image the fine structure of upper mantle and transition zone (TZ) beneath the western US. We map the topographies of seismic discontinuities by stacking data by common conversion points along profiles. Systematic depth and amplitude measurements are performed not only for the well-known ‘410’ and ‘660’ int...

PURPOSE Determine the incidence of anterior (AZ) and transition (TZ) zone prostate cancers using a transperineal mapping approach. METHODS A retrospective review of 137 patients with history of previous negative biopsy undergoing transperineal saturation biopsy for an elevated prostate-specific antigen (PSA), high-grade prostate intraepithelial neoplasia, atypical small acinar proliferation h...

PURPOSE To investigate the level of inaccuracy of retinal thickness measurements in tilted and axially stretched optical coherence tomography (OCT) images. METHODS A consecutive series of 50 eyes of 50 patients with age-related macular degeneration were included in this study, and Cirrus HD-OCT images through the foveal center were used for the analysis. The foveal thickness was measured in t...

This article reports on the design and practical development of RF co-designed MMIC components that exhibit function a bandpass filter an isolator. They are based cascaded non-reciprocal frequency-selective stages (NFSs), one-pole/two-transmission zero (TZ) multi-resonant stages, impedance inverters. The combination these results in two-port network exhibits nonreciprocal quasi-elliptic (NBPF) ...
