Mathematical Modeling of the Role of Cytokines in Sindbis Virus Treatment of Glioblastoma
ABSTRACT Oncolytic viruses, specifically Sindbis virus (SINV), combined with cytokines show promising results in slowing glioma progression, but a quantitative understanding of their effects remains limited. In this study, we use an ordinary differential equation (ODE) model to examine the effect of adding cytokines to oncolytic SINV therapy.

ABSTRACT Elite performance in Olympic winter sports depends on the interplay among the athlete, equipment, and the snow or ice. This naturally evolves with temperature, humidity, wind, preparation, and contact between the equipment and its surface. Together, these factors continuously rebalance the forces of gravity, aerodynamic drag, and friction ...
