flagrans and 50 g of pellets of the fungus M. thaumasium, associated and in a single oral dose; group 2, 100 g of pellets containing D. flagrans and 100 g of pellets containing M. thaumasium, associated and in a single oral dose; group 3, control. Faecal samples were collected from animals in the treated and control groups at time intervals BVD-523 MAPK inhibitor of 12, 24, 36, 48, 60 and 72 h after the administration of treatments and placed in Petri dishes containing 2% water-agar (assay A) and cups for coprocultures (assay
B). Subsequently, 1000 cyathostomin L-3 were added to each Petri dish (assay A) and 1000 cyathostomin eggs were added to each coproculture (assay B) of fungi-treated and control groups. At the end of 15 days, there was observed that the two associations of pellets containing the fungi tested showed predatory activity after passing through the gastrointestinal tract of horses (assay A). In assay B, all the intervals studied showed reduction rate in the number of L-3 recovered from coprocultures exceeding 80%. However, no difference (p > 0.01) was seen in recovery of not predated L-3 between the fungi-treated groups in the time intervals studied. The results obtained showed that the associations of pellets (50
or 100 g of each fungal isolate) were viable after passage through the gastrointestinal tract in horses and could be used in natural conditions. (C) 2012 Elsevier Ltd. All rights reserved.”
“Purpose: To assess the value of vertebral body endplate signal intensity (Modic) changes
on magnetic resonance (MR) images in predicting a painful disk, with provocative diskography as the reference KU55933 standard.
Materials and Methods: Lumbar spine diskograms and prediskogram MR images of 736 patients (2457 disks) were Fer-1 mouse retrospectively reviewed as part of an institutional review board-approved HIPAA-compliant protocol. Each disk was assigned a Modic subtype: type 0, normal; type 1, nonfatty high signal intensity; type 2, fatty; and type 3, sclerosis. Statistical analysis involved use of a 2 x 2 contingency table of diskogram results for each of the subtypes. The subtype sensitivity, specificity, positive predictive value (PPV), negative predictive value, and confidence intervals (CIs) were calculated. Similar analyses of other MR variables (such as disk herniation, high signal intensity zone, and spondylolisthesis) and type 1 signal intensity changes also were performed.
Results: Type 1 changes (n = 155) had a high PPV (0.81; 95% CI: 0.74, 0.87) for a provocative diskogram. Type 2 changes (n = 126) had a lower PPV (0.64; 95% CI: 0.55, 0.72) for a positive diskogram. Type 3 changes (n = 21) had a PPV (0.57; 95% CI: 0.34, 0.78) that was not significant for a positive diskogram. The PPV of an endplate with a type 1 change (hereafter, type 1 endplate) for a tear in the annulus fibrosis of the disk was also insignificant (0.
