In order to study the morphological interrelationships between immunocytochemically identified neuronal systems, a double labelling procedure - suitable for correlative light and electron microscopic observations - is introduced. The technique is based on the consecutive use of the silver-gold (SG) intensified and non-intensified forms of the oxidized(More)
This multicenter, randomized, double-blind study compared the efficacy and safety of once-daily oral granisetron 2 mg (n = 134) and placebo (n = 126) as prophylaxis for nausea and emesis in patients receiving upper abdominal fractionated radiotherapy. Patients were scheduled to receive 10-30 fractions of radiotherapy; granisetron (two 1-mg tablets) or(More)
The performance of the serum complement fixation (CF) test was compared with that of a serum agar gel immunodiffusion (AGID) test on 74 subclinically infected and 154 uninfected cattle in 6 commercial midwestern dairy herds with Mycobacterium paratuberculosis infection and on 30 cattle in a herd that was free of infection. Infection status of cattle within(More)
Concurrent bacteriologic culture of feces and agar gel immunodiffusion (AGID) testing was performed on all cows and bred heifers over 14 months old in 10 dairy herds during a 32-month period to determine the effectiveness of the AGID test for the detection of subclinical paratuberculosis. Herds were sampled 5 times and, when possible, culled animals were(More)
A monoclonal antibody (MCA) to enterotoxigenic Escherichia coli K99 antigen agglutinated K99+ enterotoxigenic E. coli strains B44 (O9:K30;K99;F41:H-) and B41 (O101:K99;F41:H-) grown at 37 degrees C but not at 18 degrees C. The MCA, which was characterized as immunoglobulin G1, reacted specifically with K99 antigen in an enzyme-linked immunosorbent assay and(More)
A new method of visualizing the angioarchitecture of tissues has been developed that uses blood components in nonperfused materials. Tissue blocks are fixed in 4% paraformaldehyde and cut with a vibratome into 50-60 micron sections. Endogenous peroxidase in red blood cells is then reduced in the presence of hydrogen peroxide with the resultant oxidation of(More)
Spectra obtained from recent telescopic observation of 1-Ceres and laboratory measurements and theoretical calculations of three component mixtures of Ceres analog material suggest that an ammoniated phyllosilicate is present on the surface of the asteroid, rather than H(2)O frost as had been previously reported. The presence of an ammoniated(More)
The structure of a procapsid of the single-stranded DNA bacteriophage ++phiX174 was determined to 3.5 A resolution. The crystal space group was I213 with a unit-cell length of 774 A. The unit cell contained 16 icosahedral virus particles, each situated on a crystallographic threefold axis. Thus, there are two independent one-thirds of a particle per(More)
