OBJECTIVE The goal of this study was to determine if specific measures of heart rate variability (HRV) are associated with the total score on a new seven-item inventory for sudden unexplained death in epilepsy (SUDEP). METHODS Nineteen subjects with intractable partial seizures, at least three per month, were enrolled in a randomized clinical trial of(More)
Several novel astroviruses have been recently discovered in humans and in other animals. Here, we report results from our surveillance of astroviruses in human and rodent faecal samples in Hong Kong. Classical human astroviruses (n=9) and a human MLB1 astrovirus were detected in human faecal samples (n=622). Novel astroviruses were detected from 1.6 % of(More)
To determine risk for Middle East respiratory syndrome coronavirus transmission from camels to humans, we tested serum from 191 persons with various levels of exposure to an infected dromedary herd. We found no serologic evidence of human infection, suggesting that zoonotic transmission of this virus from dromedaries is rare.
Ebola virus is currently causing an unprecedented outbreak in West Af-rica. The pathogen is classified as a biosafety level 4 (BSL-4) 1 pathogen and should be handled only in high-level biosafety settings (1). Virus neutralization is considered to be the gold standard serological assay for infections, but in the case of Ebola, this test requires culturing(More)

Inaccuracies in prediction of circulating viral strain genotypes and the possibility of novel reassortants causing a pandemic outbreak necessitate the development of an anti-influenza vaccine with increased breadth of protection and potential for rapid production and deployment. The hemagglutinin (HA) stem is a promising target for universal influenza(More)
Avian H7N9 influenza viruses may pose a further threat to humans by reassortment with human viruses, which could lead to generation of novel reassortants with enhanced polymerase activity. We previously established a novel statistical approach to study the polymerase activity of reassorted vRNPs (Influenza Other Respir Viruses. 2013;7:969-78). Here, we(More)
OBJECTIVES Reassortment of influenza A viruses can give rise to viral ribonucleoproteins (vRNPs) with elevated polymerase activity and the previous three pandemic influenza viruses contained reassorted vRNPs of different origins. These suggest that reassorted vRNP may be one of the factors leading to a pandemic virus. In this study, we reconstituted(More)
