Lungs from animals infected with the contemporary flu strain
showed few, if any, of these effects.
To know the extent to which configurations and conditions show deviations from this, one needs to test a range of samples under different conditions to different strain
How to identify profitable strains
and market them are just two.
In reassortment, scientists inject fertilized chicken eggs with both a standard nonpathogenic influenza strain
known to grow well in eggs and the circulating strain
that carries the genes expressing the desired HA and NA protein subtypes.
Everyone has rolled out the red carpet for us,'' Strain
The specimens were then aged under strain
for several different periods of time.
The new trial vaccine is specific to the H5N1 strain
of avian influenza, but can be easily and quickly adapted to protect against other strains
of the virus.
Together, the cyclic stress strain
curve and the strain
-life curve enable designers to account for local stress-strain
conditions at stress concentrations like fillets.
In these methods either the Fourier coefficients, or diffraction line profiles themselves are calculated using models for the strain
and size distributions in the specimens.
He went on to discuss how HIV strains
are defined on the basis of their tropism.
These products, developed using techniques of plasmid curing and conjugal transfer, have already proven superior to non-improved native Bt strains
marketed by others.
The origins of the more virulent strains
of Toxoplasma were first documented in a 2001 Science paper from Boothroyd's group; the researchers found that the recombination of two relatively benign strains
of Toxoplasma can result in a thousand-fold increase in their ability to cause serious disease.
The DNA of 1 outbreak strain
, which infected as many as l0 people, was tested only once in this study.
More than 80 percent of the infected patients had acquired a single, fluoroquinolone-resistant form of the pathogen, making that strain
primarily responsible for the Quebec outbreaks, Loo's team concludes.
These instruments range from custom servohydraulic testers for high strain
rate experiments to electromechanical instruments.
