The purified VP7 protein was recognized by antibody to BTV in Western blot analysis. The capability of the recombinant VP7 protein to differentiate hyperimmune serum of rabbit to BTV from normal rabbit serum was evident in the enzyme-linked immunosorbent

assay (ELISA). The purified VP7 reacted well with the 24 BTV serotype-specific sera obtained from OIE Reference Laboratory on bluetongue. Our results indicated that the expressed VP7 protein could be used as antigen for development of antibody-capture ELISA for detection BTV group-specific antibodies. This recombinant protein may also be used as antigen in competitive ELISA format. (C) 2008 Elsevier B.V. All rights reserved.”
“Alzheimer’s disease is a progressive neurodegenerative disease clinically Selleckchem Fedratinib characterized by dementia selleckchem and neurobehavioral deterioration. Hippocampal neurons are vulnerable to injury induced by Alzheimer’s disease. The immediate early gene c-Fos has been used as a marker of neuronal activity. In the present study, we investigated the effects of treadmill exercise on long-term memory capacity and c-Fos expression in the hippocampus of rats with Alzheimer’s disease. The rat model of Alzheimer’s disease used in the present study was induced by the intracerebroventricular (ICV) injection of streptozotocin (STZ) using a stereotaxic instrument. The rats in the exercise

Elacridar mw group were forced to run on a treadmill for 30 min once daily for 14 consecutive days starting at 3 days after the ICV injection of STZ. The results of the present study showed that ICV injection of STZ impaired long-term memory capacity and decreased the number of c-Fos-positive cells in several regions of the rat hippocampus. However, treadmill exercise alleviated long-term memory deficits and enhanced c-Fos expression in the rats with ICV injection of STZ. The results of the present study showed that treadmill exercise could be a useful strategy for treating several neurodegenerative diseases. (C) 2008 Elsevier Ireland Ltd. All rights reserved.”
“Real-time RT-PCR (RT-qPCR) was used routinely

for laboratory diagnosis during the 2006/2007 bluetongue virus (BTV) serotype 8 epidemic. In the present study the impact of pooling and multiplexing strategies on RT-qPCR are assessed. To avoid any bias in the pooling experiments, 121 BTV-8 positive blood samples with a low to high viral load were selected and pooled individually with nine negative blood samples. Analyses of the individually and pooled samples indicated an overall mean difference of 4.32 Ct-values. The most pronounced differences were observed in samples with the lowest viral load of which 70% could no longer be detected after pooling. The pooling strategy is therefore not suitable for BTV detection at the individual level since animals infected recently may be missed.
