Introduction: Prostatic specific antigen (PSA) is an excellent tumor marker, but it is not specific for prostate cancer. We evaluated the accuracy of PSA adjusted for transition zone volume calculated by transrectal ultrasonography in predicting prostate cancer in men compared with PSA density. Material and Methods: PSA adjusted for transition zone volume was obtained from 100 patients who u...
giant unilamellar vesicles (guvs) consisting in self-closed lipid bilayers of 0.5-100 µm diameter are considered as oversimplified models of cells because of their biological membrane and micrometric size while large unilamellar vesicles (luvs) of 100-500 nm diameter have applications in drug delivery. to improve structural and mechanical properties of these vesicles, we have developed two cate...
Similarities and differences in the thermal behaviour of deuterated and nondeuterated ammonium perchlorate provide insights into the mechanism of its thermal decomposition. Thermal decomposition of NH4ClO4 and ND4ClO4 always begins in the bulk of the crystals. In both cases decomposition stops when the degree of conversion is about 30%, giving porous products which undergo the same phase transi...
introduction: aim of this study was to assess the association between prostate calcification in transrectalultrasound (trus) and sono- guided needle biopsy in prostate cancer (pca). methods: a cross-sectional study was performed on patients referred to imam khomeini hospital between 2005 and 2011 who underwent trus biopsy due to increased psa or abnormal dre. the serum levels of psa, prostate v...
Structures of two derivatives of the curved fluoradene ring system (C(19)H(12)) have been determined. Both have phases that are highly pseudosymmetric. At room temperature crystals of 7b-triisopropylsilylfluoradene (C(28)H(32)Si) have a P1 cell that contains two independent molecules (Z' = 2) and that is almost centered. Crystals of 7b-(2,4-dinitrophenyl)fluoradene (C(25)H(14)N(2)O(4)) have bot...
Theoretical computation of the pressure dependence superconducting state parameters of binary Ca60Al40 is reported using model potential formalism. Explicit expressions have been derived for the volume dependence of the electron–phonon coupling strength λ and the Coulomb pseudopotential μ* considering the variation of Fermi momentum KF and Debye temperature ӨD with volume. Well known Ashcroft’s...
