The reaction of intracomplex proton transfer (44BPY(-.)...HO-H) (R)-->44BPYH(.)+ OH(-) that follows the photoreduction of 4,4'-bipyridine (44BPY) into its anion radical 44BPY(-) in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) is investigated in acetonitrile-water mixtures by using picosecond transient absorption. The dependence of the appearance kinetics of the 44BPYH(.) radical on the...
To determine the effect of ischemia on myocardial clearance of thallium-201 (201TI), we studied 12 dogs with ischemia produced after the injection of Tl. TI was given I.V. 10 minutes before left anterior descending (LAD) coronary artery ligation. 85Sr-microspheres (MS) were administered 5 minutes later, and control biopsies were obtained from the myocardium. The LAD was tied and repeat biopsies...

Spallation cross sections for 250 MeV to 2 GeV protons bombarding thin targets of natural copper were determined via the foil activation technique. This energy range is important cosmogenic radionuclide production in interplanetary space bombardment by galactic cosmic-ray protons. Cross are reported 60Co, 58Co, 57Co, 56Co, 56Ni, 59Fe, 54Mn, 52Mng, 51Cr, 48V, 47Sc, 46Sc, 44Scm, and 7Be. The 44Sc...

The use of biochar has received growing attention because of its ability to improve the physicochemical properties of highly weathered Ultisols and Oxisols, yet very little research has focused on its effects in Aridisols. We investigated the effect of low or high temperature (250 or 500°C) pyrolyzed switchgrass () biochar on two Aridisols. In a pot study, biochar was added at 2% w/w to a Declo...
The fate of hydrocortisone in man has been extensively studied (l-7) but the quantitative aspects of the transformation to its many metabolites in individual normal subjects leave much to be desired (8-16). This study reports the metabolism of an intravenous dose of hydrocortisone-4-Cl4 in five normal male subjects and of an oral dose in one of these subjects. The metabolites” cortol, /I-cortol...
Phytotoxic Activity of the 6-acetyl-5-hydroxy-2isopropenyl-2,3-dihydrobenzofurane (1) isolated from Trichocline reptans (Asteraceae) was investigated in two weed species. Results indicate that the best growth inhibition effect ocurres on Chenopodium album weed. Phythotoxic effect of the T. reptans chloroformic extract and of the benzofurane are discussed and compared in the two weed species. In...
