Molecular docking analysis of zanamavir with haem agglutinin neuraminidase of human para influenza virus type 3.

The human para influenza virus (HPIV) type 3 is an imperative respiratory virus which cause upper and lower respiratory infections. The receptor involved in the viral infection is haem agglutinin neuraminidase. It is of interest to study the interaction of haem agglutinin neuraminidase with zanamavir (4-GU-DANA), a known antiviral drug.

Anti-dengue activity of extracts and quantification of dengue viral inhibition by SYBR green reverse transcription polymerase chain reaction.

Background: Dengue virus is a leading cause of illness and death in the tropics and subtropics. As many as 400 million people are infected yearly. Dengue is caused by any one of four related viruses transmitted by mosquitoes.
