OBJECTIVE To analyse the histological components of the transition zone in both normal human prostate and benign prostatic hyperplasia (BPH), and to determine the volumetric density (Vv) of the different elements (connective tissue, smooth muscle cells, acini and total stroma). MATERIALS AND METHODS Samples of BPH tissue from the transition zone were obtained from 16 patients with clinical sy...

A diffusion barrier at the transition zone enables the compartmentalization of signaling molecules by cilia. The BBSome and the small guanosine triphosphatase Arl6, which triggers BBSome coat polymerization, are required for the exit of activated signaling receptors from cilia, but how diffusion barriers are crossed when membrane proteins exit cilia remains to be determined. In this study, we f...

The Makran Coast (Iranian Coastline of the Oman Sea on the Northern Indian Ocean) plays an important role in country’s future navigation and trade due to its accessibility. In 2014, the Iranian Makran coastline was selected by the PMO to be studied as the Phase 6 in the series of Monitoring and Modelling Studies of Iranian Coasts with all disciplines being in investigated including currents. Al...

[1] Teleseismic receiver function analysis of data from six dense arrays in the western U.S. is used to inves­ tigate mantle transition zone (MTZ) discontinuities and the prevalence of a low‐velocity layer atop the 410 km discontinuity (410‐LVL). Negative polarity Ps arrivals indicative of a low‐velocity layer with a top 25–60 km above the 410 are identified in 8–11 out of 18 stacks of receiver...

BACKGROUND The hybrid zone between the primarily forest-dwelling American toad, Anaxyrus americanus, and the prairie-adapted Canadian toad, A. hemiophrys, in southeastern Manitoba is known to have shifted its position during the past 50 years. Hybrid zones are areas of interbreeding between species and their movement across a landscape should reflect their underlying dynamics and environmental ...

conclusions using tzpsad as an adjunct to psa may improve the specificity of psa in the diagnosis of pca and decrease the number of unnecessary prostatic biopsies in iranian men with serum psa level < 20 ng/ml. results among 1120 men who were eligible for enrolment, prostate cancer was detected in 265 patients. mean serum psa levels were 9.7 ± 4.3 ng/ml and 8.5 ± 3.7 ng/ml in patients with and ...

magnetic data inversion has a prominent role in geo-structural investigations. as lots of geological structures, such as faults, dykes, contacts etc are elongated in a specific direction, 2d algorithms became widespread during the previous years. modifying the existing algorithms on 3d data inversion, a method has been proposed for 2d inversion of profile magnetic data, based on the physical pa...
