Isolates were tested in the NI assay by using the NA-Fluor kit (6).
For sensitivity analyses, we repeated the time-series analyses after either imputing source concentrations for the days without samples from any stations (751 days) by linear interpolation using the na.approx function in the R zoo package or by replacing the missing data with nonmissing measurement values from the previous day.
Full-length Na-apr-1wt was synthesized in codon-optimized form for expression in E. coli by GeneArt AG, using the Na-apr-1 cDNA sequence in GenBank (accession no. AJ245459).
For TBEV-specific real-time PCR (5 ), ticks were homogenized in 0.5 mL nucleic acid extraction buffer and RNA/DNA extracted from 0.2 mL homogenate by using the MagNA Pure total NA kit (Roche, Indianapolis, IN, USA).
We converted miRNA-RefSeq pairs (as returned by PITA) to miRNA-probeset_id by using the HGU133 Plus 2.0 NA-27 table provided by Affymetrix.
In the present study, we have screened 9mer peptide epitopes from available influenza A viral protein sequences including the highly variable surface glycoproteins HA and NA by using the NetCTL algorithm for epitope prediction [11] and the EpiSelect algorithm for broad coverage of all available Influenza A strains [12].
Assays were carried out at 25 °C by using the reaction buffer of 50 mM Na-phosphate buffer (pH 7.8) including 0.033 mM NBT, 10 mM l-methionine, 0.66 mM Na2EDTA and 0.0033 mM riboflavin.
For a total of 253 samples, partial sequences of the HA and NA segments were analyzed by using the maximum parsimony method.
The sodium percent (Na%) values was obtained by using the following equation: {text{Na}}% = {text{Na}}^ times 100/left[ {{text{Ca}}^{2 + } + {text{Mg}}^{2 + } + {text{Na}}^ + {text{K}}^ right] where all ionic concentrations are expressed in meq/l.
The chemiluminescent NA inhibition assay was performed by using the NA Star Kit Applied Biosystemss, Tokyo, Japan) with slight modifications of the instructions provided by the manufacturer.
To explain the link between Nav channel activation and vascular contraction, we tested the participation of the Na+-Ca2+ exchanger by using the blocker KB-R7943 reportod to inhibit the reverse mode of exchange (Ca2+ influx/Na+ efflux) [23].
