A Class Age-Structured HIV/AIDS Model with Impulsive Drug-Treatment Strategy

A Class Age-Structured HIV/AIDS Model with Impulsive Drug-Treatment Strategy

We formulate an HIV/AIDS transmission model that considers the dependence of HIV/AIDS progress on infection age the time since infection , disease age the time elapsed since the onset , and impulsive antiretroviral treatment. Since no effective vaccine is available for HIV/AIDS, our impulsive disease-control strategy is targeted at infected individuals I control . Thus the model only includes i...

Stability Results on Age-structured Sis Epidemic Model with Coupling Impulsive Effect

We develop an age-structured epidemicmodel for malaria with impulsive effect, and consider the effect of blood transfusion and infected-vector transmission. Transmission rates depend on age. We derive the condition in which eradication solution is locally asymptotically stable. The condition shows that large enough pulse reducing proportion and relatively small interpulse time lead to the eradi...

A Mathematical Model for the Dynamics of a Fish Algae Consumption Model with Impulsive Control Strategy

A dynamic mathematical model of fish algae consumption with an impulsive control strategy is proposed and analyzed in detail. It is shown that the system has a globally asymptotically stable algae-eradication periodic solution which can be obtained using the Floquet theory of impulsive differential equations and small-amplitude perturbation techniques. The conditions for the permanence of the s...

Au Nanoparticle Loaded with 6-Thioguanine Anticancer Drug as a New Strategy for Drug Delivery

In this study we suggested a new strategy for drug delivery of 6-thioguanine (6-TG) as a cancer drug by loading of this thiolic drug at a surface of Au nanoparticles. For this goal, we synthesized Au nanoparticle (Au/NPs) by reduction of tetrachloroauric (III) acid solutions by sodium borohydride and characterized Au/NPs by X-ray powder diffraction (XRD), dynamic light scattering (DLS), Ultravi...
