Sentence examples for a virus where from inspiring English sources

The importance of the four arginines that intercalate into 7SK is highlighted by the fact that in a virus where mutations are a frequent occurrence with Tat being one of the highly variable proteins41, these arginines remain highly conserved (>92% conservation frequency in HIV-1 subtype B).

We also created a virus where PuroR expression was driven by the 7xTcf promoter (7xTcf-PuroR virus, 7TP, Fig. 2D).

The Beringia area has been proposed to be an important gateway between Eurasia and North America for influenza A virus, where the meeting of birds and viruses from different hemispheres can allow disease transmission to occur [25].

A typical example is influenza A virus, where virus-cell fusion activity is induced by post-translational proteolytic cleavage of the envelope glycoprotein that is mediated by trypsin-like protease in the bronchial epithelium and airway secretion [9].

Wild avian species of wetlands and aquatic environments such as the Anseriformes (particularly ducks, geese, and swans) and Charadriiformes (particularly gulls, terns, and waders) have been recognized as the major natural reservoirs of influenza A viruses where the viruses are maintained predominantly by asymptomatic birds, indicating a long-standing history of endemic infection [ 1].

The A(H1N2) viruses circulating during 2000 2003 were found to have a similar genetic make-up to those that had circulated sporadically in China during 1988 89 in that they were essentially an A(H3N2) virus where the HA had been replaced with the HA from the A(H1N1) virus (33, 38 ).

"But now we've seen the scale of a particular virus, where a lot of people died and quickly, we had the ability to treat or maybe prevent those infections sitting in a cupboard," Mackay said.

But now we've seen the scale of a particular virus where a lot of people died and quickly, and we have the ability to treat or maybe prevent those infections sitting in a cupboard.

This newly formed strain would be involved in another event that gave rise to the hk1073 reassortant by acquiring a HA segment from an H9Nx virus (where Nx stands for any type of NA).

For a novel virus, where such genotypic findings would not yet be correlated with phenotypic data, the overall sequence and structure of the genome may still yield valuable insights into viral transmission and mechanisms of pathogenesis.

We have previously described an oncolytic Ad5 virus where the chromogranin-A (CgA) promoter controls expression of the adenoviral E1A gene, Ad[CgA-E1A] [11].
