Pharmacokinetics of enrofloxacin and danofloxacin in plasma, inflammatory exudate, and bronchial secretions of calves following subcutaneous administration
(1999-08)
Enrofloxacin (2.5 mg/kg of body weight) and danofloxacin (1.25 mg/kg) were administered subcutaneously to ruminating calves (n = 8) fitted with subcutaneous tissue cages. Concentrations of enrofloxacin, its metabolite ...
The relationship between the number and size of nematodes in the abomasum and the concentration of pepsinogen in ovine plasma
(1999-08)
Six-month-old lambs that had been naturally infected with predominantlyTeladorsagia (Ostertagia) circumcinctawere tested for plasma pepsinogen concentrations because pepsinogen concentrations may reflect the extent of ...
Predatory behaviour of trapping fungi against srf mutants of Caenorhabditis elegans and different plant and animal parasitic nematodes
(1999-07)
The initial infection process of nematode-trapping fungi is based on an interaction between the trapping structure of the fungus and the surface of the nematode cuticle. A bioassay was designed to investigate the predatory ...
Measurements of proton radiative capture cross sections relevant to the astrophysical rp- and gamma-processes
(1999-06-21)
Measurements have been made of the Zr-96(p,gamma)Nb-97, Sn-112(p,gamma)Sb-113, and Sn-119(p,gamma) Sb-120 cross section excitation functions, Incident proton energies ranged from 2.8 MeV to 8.5 MeV. These reactions are ...
MK-801 interaction with the 5-HT transporter : A real-time study in brain slices using fast cyclic voltammetry
(1999-06-01)
The effects of a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist dizocilpine ((+)-MK-801) and a competitive NMDA antagonist, (+/-)-3-2-carboxypiperazin-4-yl-propyl-1-phosphonic acid (CPP) were compared in ...
Novel selective compounds for the investigation of imidazoline receptors
(1999-06)
Over several years our group has sought to synthesize and identify selective ligands for imidazoline (I) receptors, in particular the I2 binding site. As a consequence, [3H]2-(2-benzofuranyl)-2-imidazoline (2BFI) has proved ...
The teachability of children with naive theories: An exploration of the effects of two teaching methods
(1999-06)
Background. The Representational Redescription model of cognitive development (Karmiloff-Smith, 1992) identified a level when a child's representation of a task may be incorrect but difficult to access or change. On the ...
Adaptive leaky integrator models of cerebellar Purkinje cells can learn the clustering of temporal patterns
(1999-06)
We have shown previously that the metabotropic glutamate receptor signalling network in a cerebellar Purkinje cell can implement adaptive postsynaptic delays. Here we present a leaky integrator version of the Purkinje cell ...
Ascospores as primary inoculum for epidemics of white leaf spot (Mycosphaerella capsellae) in winter oilseed rape in the UK
(1999-06)
In the UK, conidia of Pseudocercosporella capsellae, the anamorph of Mycosphaerella capsellae, were observed on white leaf spot lesions on leaves throughout the growing season. Ascomata were not observed on lesions on ...
Meloidogyne incognita surface antigen epitopes in infected Arabidopsis roots
(1999-06)
Surface-coat epitopes of Meloidogyne incognita were detected in root tissues of Arabidopsis thaliana during migration and feeding site formation. A whole-mount root technique was used for immunolocalization of surface coat ...
