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 ...

In support of a large, combined Australia-United States of America military exercise at Shoalwater Bay in south-eastern Queensland during March 1997 (TANDEM THRUST 97), the United States Navy sent the Deployed Public Health Laboratory (DPHL) into the field with the forces. The purpose of this was preventative medicine as well as disease and vector surveillance. Among the numerous potential thre...

BACKGROUND Africa is the most affected continent with 200,000 new born affected by sickle cell anemia annually with of 5% of under five deaths. Nigeria has the largest sickle cell gene pool in the world with about 2% of all babies born to Nigerian parents. This study therefore sets out to assess the prevention practices influencing the frequency of occurrence of vaso-occlusive crisis among pati...

INTRODUCTION Disclosure may reduce the transmission of HIV by raising awareness and decreasing risky behavior, thus status disclosure is an issue to be addressed for HIV prevention and treatment. The objective of this study was to determine the prevalence and determinants of HIV status disclosure to sexual partners among People Living with HIV/ AIDS (PLWAs) in Ogun state, Nigeria. MATERIALS A...

Laboratory methods and questionnaires to assess the relative reinforcing value of food (RRV-F) have been developed, but this is the first study to validate an online questionnaire measure of the RRV-F. Participants (281 college students) completed an online survey assessing demographic variables, food preferences, and the RRV-F. A subsample (n=21) also completed a laboratory food choice session...

Ivan Havel remembers when in the late 1970s the Czechoslovakian state police began watching his apartment. For months he had been hosting unofficial science seminars, and the police didn't like it. "It politicized me, says the soft-spoken computer scientist and brother of Czechoslovakian president Vaclav Havel. "The police would check the people who came and ask them to identify 'themselves. Th...

Water quantity and quality joint operation is a new mode in the present dams' operation research. It has become a hot topic in governmental efforts toward integrated basin improvement. This paper coupled a water quantity and quality joint operation model (QCmode) and genetic algorithm with Soil and Water Assessment Tool (SWAT). Together, these tools were used to explore a reasonable operation o...
