Countering aerosolized filovirus infection is a major priority of biodefense research.  Aerosol models of filovirus infection have been developed in knock-out mice, guinea pigs and non-human primates; however, filovirus infection of immunocompetent mice by the aerosol route has not been reported.  A murine model of aerosolized ros

Abstract Antisense transcripts are a unique group of non-coding RNAs and play regulatory roles in a variety of biological processes, including circadian rhythms.Per2AS is an antisense transcript to the sense core clock flexcon reverse osmosis water storage tank gene Period2 (Per2) in mouse and its expression is rhythmic and antiphasic to Per2.To un
