Positron emission tomography in combination with the newly introduced catecholamine analogue [11C]hydroxyephedrine ([11C]HED) enables the noninvasive delineation of sympathetic nerve terminals of the heart. To address the ongoing controversy over possible reinnervation of the human transplant, 5 healthy control subjects and 11 patients were studied after cardiac transplant by this imaging appro...

Assessing myocardial perfusion using Rb-PET is emerging as a valuable clinical tool. The rapid decay (T = 76 s) allows for absolute quantification of both rest and stress perfusion within 30 minutes. In addition to evaluation of epicardial disease with perfusion defects, also evaluation of balanced coronary and small vessel disease is possible. For further evaluation of how Rb-PET can be used c...

An aprE mutant from B. subtilis 168 lacking the connecting loop Leu(75)-Leu(82) which is predicted to encode a Ca(2+) binding site was constructed. Expression of the mutant gene (aprEDeltaLeu(75)-Leu(82)) produced B. subtilis colonies lacking protease activity. Intrinsic fluorescence analysis revealed spectral differences between wild-type AprE and AprEDeltaL(75)-L(82). An AprEDeltaL(75)-L(82) ...

let $g$ be a finite $p$-soluble group‎, ‎and $p$ a sylow $p$-sub-group of $g$‎. ‎it is proved‎ ‎that if all elements of $p$ of order $p$ (or of order ${}leq 4$ for $p=2$) are‎ ‎contained in the $k$-th term of the upper central series of $p$‎, ‎then the $p$-length of‎ ‎$g$ is at most $2m+1$‎, ‎where $m$ is the greatest integer such that‎ $p^m-p^{m-1}leq k$‎, ‎and the exponent of the image of $p$...

the length-weight relationship (lwr) and condition factors (cf) of 180 the oriental river prawn macrobrachium nipponense collected from southern coasts of the caspian sea from may through september 2012 were studied. shrimp samples were taken and immediately transferred to the laboratory of fish biology at university of guilan for further analyses. length, weight and other external features of ...

water logging stress is one of the most important factors which affect wheat production particularly in western regions of golestan province. this experiment was carried out in order to evaluate of six genotypes (n-81-18, arta, moghan, n-80-19, urwyt-82-11 and urwyt-82-17) of bread wheat in water logging condition at 2006-2007 growing season in gorgan agricultural research station. the experime...

In this note we prove the two formulae conjectured by D. W. Boyd [Experiment. Math. 7 (1998), 37-82], m(y(x + 1) + y(x + 6x + 1) + (x + 1)) = 8 3 L ′ (χ−4,−1), m(y(x + 1) + y(x − 10x + 1) + (x + 1)) = 20 3 L ′ (χ−3,−1), where m denotes the logarithmic Mahler measure for two-variable polynomials.
