A reassortant, TyRh, was isolated after coinfection of MA104 cells with avian Ty-1 and simian RRV rotaviruses. Hybridization and serological studies showed that the reassortant's 4th gene, which encodes Vp4, was derived from the simian RRV rotavirus parent, whereas the remaining 10 genes were derived from the avian Ty-1 rotavirus parent.

Beat-to-beat variability of the QT interval (QTV) is sought to provide an indirect noninvasive measure of sympathetic nerve activity, but a formal quantification of this relationship has not been provided. In this study we used power contribution analysis to study the relationship between QTV and muscle sympathetic nerve activity (MSNA). ECG and MSNA were recorded in 10 healthy subjects in the ...

Together, these tools were used to explore a reasonable operation o...

Golden alga, Prymnesium parvum, has become a rising concern in terms of conservation. This is due to the toxic blooms they create that kill populations of fish and phytoplankton. P. parvum produce prymnesin toxins, which cause the blooms to be so dangerous. Previous research has claimed that prymnesins lyse cells and toxify other cells, neurons and fish. Specifically, the toxins have been shown...
