Salmonella enterica serovar typhimurium (S. typhimurium) is globally distributed and causes massive morbidity and mortality in humans and animals. S. typhimurium carries Salmonella plasmid virulence (spv) locus, which is highly conserved and closely related to bacterial pathogenicity, while its exact role in host immune responses during infection remains to(More)
OBJECTIVE To investigate the effects of transcutaneous electrical nerve stimulation (TENS) on motor function in children with spastic cerebral palsy (CP). METHODS After signing the informed consent, 78 children with CP, aged 45.6 +/- 8.5 months (36 to 58 months), were randomly divided into a TENS group (n = 40) and a control group (n = 38). All the(More)
Captorhinids, a clade of Paleozoic reptiles, are represented by a rich fossil record that extends from the Late Carboniferous into the Late Permian. Representatives of this clade dispersed from the equatorial regions of Laurasia into the temperate regions of Pangea during the Middle and Late Permian. This rich fossil record shows that there was an(More)
The short-term responses of H(2)O(2)-depletion-related parameters in moss Hypnum plumaeforme to the combined stress induced by Pb and Ni were investigated. The results showed that the Pb and Ni stress induced dose-dependent accumulation of hydrogen peroxide (H(2)O(2)). The increase of peroxidase (POD) activity and decrease of ascorbate peroxidase (APX)(More)
OBJECTIVE To study the content of mineral elements and the principal components in Gastrodia elata. METHOD Mineral elements were determined by ICP and the data was analyzed by SPSS. RESULT K element has the highest content-and the average content was 15.31 g x kg(-1). The average content of N element was 8.99 g x kg(-1), followed by K element. The(More)
