Rhizobium japonicum serotype 123 was enumerated in soil and rhizospheres by fluorescent antibody techniques. Counting efficiency was estimated to be about 30%. Indigenous populations of strain 123 ranged from a few hundred to a few thousand per gram of field soil before planting. Rhizosphere effects from field-grown soybean plants were modest, reaching a maximum of about 2 x 10 cells of strain ...

UNLABELLED We compared functional imaging modalities including PET with 6-(18)F-fluorodopamine ((18)F-DA) with (123)I-metaiodobenzylguanidine ((123)I-MIBG) and somatostatin receptor scintigraphy (SRS) with (111)In-pentetreotide in nonmetastatic and metastatic pheochromocytoma (PHEO). METHODS We studied 25 men and 28 women (mean age +/- SD, 44.2 +/- 14.2 y) with biochemically proven nonmetasta...

BACKGROUND Gait impairment is common in parkinsonian syndromes but not specific to striatonigral dysfunction. The relationship between the dopaminergic system and gait parameters is poorly understood. This cross-sectional study aimed to determine if gait measures are related to the striatal dopamine transporters distribution using [(123)I]FP-CIT SPECT in patients with parkinsonian syndromes. ...

The aim of this study was to explore if estimates of renal function could explain variability of (123)I-metaiodobenzylguanidine ((123)I-MIBG) assessed myocardial sympathetic activity. Furthermore estimates of renal function were compared to (123)I-MIBG as predictors of cardiac death in chronic heart failure (CHF). Semi-quantitative parameters of (123)I-MIBG myocardial uptake and washout were ca...

Haloalkane dehalogenases make up an important class of hydrolytic enzymes which catalyse the cleavage of carbon-halogen bonds in halogenated aliphatic compounds. There is growing interest in these enzymes owing to their potential use in environmental and industrial applications. The haloalkane dehalogenase DhaA from Rhodococcus rhodochrous NCIMB 13064 can slowly detoxify the industrial pollutan...

1. Introduction Microbial hydrolytic haloalkane dehalogenases catalyze the cleavage of halogen-carbon bonds of a variety of aliphatic halogenated compounds, including a broad range of chlorinated (C 2 –C 6) and brominated (C 2 –C 8) alkanes, with water as the sole co-substrate, resulting in the production of halide ions, protons, and alcohols (1,2). Based primarily on substrate specificity and ...

Objectives. Both results of the odor identification and cardiac (123)I-metaiodobenzylguanidine accumulation have been investigated for their potential to enhance the detection of pathogenesis resembling that of Lewy body-related α-synucleinopathies in patients clinically diagnosed as having idiopathic REM sleep behavior disorder. Methods. We performed both the Odor Stick Identification Test for...

Mantel’s theorem says that among all triangle-free graphs of a given order the balanced complete bipartite graph is the unique graph of maximum size. We prove an analogue of this result for 3-graphs. Let K− 4 = {123, 124, 134}, F6 = {123, 124, 345, 156} and F = {K− 4 , F6}: for n 6= 5 the unique F-free 3-graph of order n and maximum size is the balanced complete tripartite 3-graph S3(n) (for n ...

Schmidt 1973; Kapusta and Rouwenhorst 1973; Weaver and Frederick 1974). However, the numbers needed to overcome indigenous rhizobia are in many cases too excessive to be practical. In much of the soybean-growing area in the north central United States, an area encompassing many soil types, indigeneous strains of Bradyrhizobium japonicum serogroup 123 dominate nodulation of soybeans (Damirgi et ...
