- چکیده:
- چکیده انگلیسی: A nonstandard finite difference (NSFD) scheme has been constructed and analyzed for a mathematical model that
describes Lotka–Volterra food web model. This new discrete system has the same stability properties as the
continuous model and,on the whole, it preservesthe same local asymptotic stability properties. Linearized stability
theory and Schur–Cohn criteria are used for local asymptoticstability of this discrete time model. Numerical
results are given to support the results.- انتشار مقاله: 02-02-1393

- چکیده:
- چکیده انگلیسی: Foot-and-mouth disease (FMD) is a severely contagious viral disease that mainly affects cloven-hoofed
livestock and wildlife. This study quantifies the cytokines mRNA expression of vaccinated guinea pigs with
FMD type O inactivated vaccine. Blood samples were collected from eight guinea pigs at 7 and 28 days after the
first vaccination. Extracted mRNAs were reverse-transcribed into cDNA and analyzed for quantification of IFN-
γ, TNF-α and IL-10 expression using relative real-time PCR assay. Our results showed that all of the genes were
upregulated. The expression of TNF-α and IL-10 genes significantly increased (P<0.05) in day 28th in
comparison to the day 7th post the first vaccination. It can be concluded that the vaccine induced immune
responses by increasing expression of the cytokines. Therefore, effects of DNA vaccines on immune system also
may be evaluated using these genes.- انتشار مقاله: 26-10-1392
