PROBLEM: This paper combines two advances to detect MERS-CoV, the causative agent of Middle East Respiratory Syndrome, that have emerged over the past few years from the new field of "synthetic biology". Both are based on an older concept, where molecular beacons are used as the downstream detection of viral RNA in biological mixtures followed by reverse transcription PCR amplification. The first advance exploits the artificially expanded genetic information systems (AEGIS). AEGIS adds nucleotides to the four found in standard DNA and RNA (xNA); AEGIS nucleotides pair orthogonally to the A:T and G:C pairs. Placing AEGIS components in the stems of molecular beacons is shown to lower noise by preventing unwanted stem invasion by adventitious natural xNA. This should improve the signal-to-noise ratio of molecular beacons operating in complex biological mixtures. The second advance introduces a nicking enzyme that allows a single target molecule to activate more than one beacon, allowing "signal amplification". Combining these technologies in primers with components of a self-avoiding molecular recognition system (SAMRS), we detect 50 copies of MERS-CoV RNA in a multiplexed respiratory virus panel by generating fluorescence signal visible to human eye and/or camera.

SOLUTION: Standard and AEGIS nicking molecular beacons detect amplicons from the Middle East respiratory syndrome coronavirus

PROBLEM: We investigated the sensitivity of human rotavirus rapid antigen detection (RAD) kits, RT-PCR and next-generation DNA sequencing (NGS) for detection of bovine group A rotavirus (RVA). The Dipstick 'Eiken' Rota (Dipstick) showed the highest sensitivity out of the seven RAD kits against all selected strains in limited dilution analyses, which was consistent with the results for equine rotavirus previously reported. RT-PCR had 10 0 -10 3 -fold higher sensitivity than the Dipstick. NGS using thirteen RT-PCR-negative fecal samples revealed that all samples yielded RVA reads and especially that two of them covered all 11 genome segments. Moreover, mapping reads to reference sequences allowed genotyping. The NGS would be sensitive and useful for analysis of less dependent on specific primers and screening of genotypes.

PROBLEM: Since 2007, repeated outbreaks of Zika virus (ZIKV) has affected millions of people worldwide and created global health concern with major complications like microcephaly and Guillain Barre's syndrome. Generally, ZIKV transmits through mosquitoes (Aedes aegypti) like other flaviviruses, but reports show blood transfusion and sexual mode of ZIKV transmission which further makes the situation alarming. Till date, there is not a single Zika specific licensed drug or vaccine present in the market. However, in recent months, several antiviral molecules have been screened against viral and host proteins. Among those, (−)-Epigallocatechin-3-gallate (EGCG), a green tea polyphenol has shown great virucidal potential against flaviviruses including ZIKV. However, the mechanistic understanding of EGCG targeting viral proteins is not yet entirely deciphered except little is known about its interaction with viral envelope protein and viral protease. Since literature has shown significant inhibitory interactions of EGCG against various kinases and bacterial DNA gyrases; we designed our study to find inhibitory actions of EGCG against ZIKV NS3 helicase. NS3 helicase is playing a significant role in viral replication by unwinding RNA after hydrolyzing NTP. We employed molecular docking and simulation approach and found significant interactions at ATPase site and also at RNA binding site. Further, the enzymatic assay has shown significant inhibition of NTPase activity with an IC50 value of 295.7 nM and Ki of 0.387 ± 0.034 µM. Our study suggests the possibility that EGCG could be considered as prime backbone molecule for further broadspectrum and multitargeted inhibitor development against ZIKV and other flaviviruses. author/funder.
