BACKGROUND Cardiac allograft vasculopathy is a key prognostic determinant after heart transplant. Detection and risk stratification of patients with cardiac allograft vasculopathy are problematic. Positron emission tomography using rubidium-82 allows quantification of absolute myocardial blood flow and may have utility for risk stratification in this population. METHODS AND RESULTS Patients w...
Positron emission tomography (PET) centers without cyclotrons use generator-produced rubidium-82 (82Rb) for assessment of myocardial perfusion. The aim of the present study was to determine whether myocardial blood flow could be assessed quantitatively with 82Rb and PET. Because the myocardial extraction fraction of 82Rb varies inversely and nonlinearly with flow and cannot be measured convenie...
The crystal structure of the title compound, poly[[(4,7,13,16,21,24-hexa-oxa-1,10-diaza-bicyclo-[8.8.8]hexa-cosa-ne)rubidium] [[(1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne)rubidium]di-μ-rubidium-μ-nona-stannide] penta-ammonia], {[Rb(C(18)H(36)N(2)O(6))][Rb(3)Sn(9)(C(12)H(24)O(6))C(12)H(24)O(6))]·5NH(3)}(n) represents the first ammoniate of a Zintl anion together with two different chelating subs...
The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(6))](n), comprises an Rb cation and a 3,5-dinitro-benzoate anion. The Rb cation is eight-coordinated by O atoms from five 3,5-dinitro-benzoate anions. On the other hand, each 3,5-dinitro-benzoate anion links five Rb cations with the carboxyl-ate groups as μ(3)-bridging. The metal atom is firstly linked by the carboxyl-ate groups into ...

The authors present a joint experimental and theoretical study of the diffraction rubidium Bose-Einstein condensate by an optical lattice in quasi-Bragg regime. results focus on losses multiport features, which could guide future studies atom interferometry.
The early phase of hypertension induced in rats by a glucocorticoid agonist RU 26988 was studied. Systolic blood pressure increased by 35 mm Hg. Water and sodium urinary excretion increased transiently, and plasma volume decreased. Total and ouabain-sensitive sodium efflux, as well as rubidium efflux, were enhanced by glucocorticoid administration. Low salt intake did not prevent hypertension. ...
