Identification of Gaeumannomyces-Graminis var. tritici and G-graminis var avenae using a DNA probe and nonmolecular methods
(1992-09)
Fungi in the Gaeumannomyces-Phialophora complex were compared using a DNA probe and by pathogenicity and other biological tests. Isolates from cereal and grass hosts which were pathogenic on cereals were differentiated as ...
Effect of probenecid on disposition kinetics of ampicillin in horses
(1992-08)
The effect of an oral dose of probenecid on the disposition kinetics of ampicillin was determined in four horses. An intravenous bolus dose (10 mg/kg) of ampicillin sodium was administered to the horses on two occasions. ...
Calculation of the He-3(He-3, 2p)He-4 AND H-3(H-3, 2N)He-4 astrophysical S-factor at low energies
(1992-08)
We have calculated the cross sections for the charge symmetric reactions He-3(He-3,2p)He-4 and He-3(He-3,2p)He-4 at sub-Coulomb energies in the potential model. Good agreement with the experimental data is obtained. The ...
Seasonal changes in primary and secondary inoculum during epidemics of leaf blotch (Rhynchosporium secalis) on winter barley
(1992-08)
Seasonal changes in numbers of conidia of Rhynchosporium secalis on debris from previous barley crops infected with leaf blotch (primary inoculum) were monitored in 1985-86 and 1986-87. In 1986-87, changes in numbers of ...

Immunological differentiation of root-knot nematodes (Meloidogyne spp) using monoclonal and polyclonal antibodies
(1992-07)
Polyclonal and monoclonal antibodies were produced to supernatants of soluble proteins from homogenates of root-knot nematodes (Meloidogyne spp.). The _antibodies were used to investigate differences between second-stage ...
Dopamine releasing actions of NMDA in rat caudate putamen studied by fast cyclic voltammetry
(1992-07)
Investigations in vitro (Clow & Jhamandas, 1989; Krebs et al., 1990) have shown that glutamic acid, acting at NMDA receptors in the absence of Mg2+ can stimulate the release of dopamine (DA) from nerve terminals in the rat ...
Splash dispersal of spores of Pseudocercosporella capsellae (white leaf spot) from oilseed rape leaves of different inclination, flexibility and age
(1992-06)
Spore dispersal gradients were fitted well by exponential models in three experiments when simulated rain fell on to oilseed rape leaves infected by Pseudocercosporella capsellae (white leaf spot). Regressions of number ...
Hydrophobic core and surface charges of human beta-2-microglobulin probed by CD measurements
(1992-05)
The roles of hydrophobic bonding and charge electrostatics in the stabilization of human beta-2-microglobulin have been probed by variations in solution conditions and monitored by circular dichroism in the near and far ...
A comparison, using dsRNA analysis, between beet soil-borne virus and some other tubular viruses isolated from sugar beet
(1992-05)
Double-stranded RNA preparations from Chenopodium quinoa leaves inoculated with two English isolates of beet soil-borne virus (BSBV), BSBV-N and BSBV-452N, a French isolate of beet necrotic yellow vein virus (BNYVV), a ...
