Figure 7From: Reconciling conflicting clinical studies of antioxidant supplementation as HIV therapy: a mathematical approachThe period of the limit cycle as a function of vitamin supplementation levels. As the vitamin supplementation level increases beyond α c = 2.63 × 1013 molecules/μL per day, changes in the dynamics of the limit cycles can be observed. Insets (a) and (b) show the limit cycle at α = 2.8 × 1013 and α = 4.45 × 1013, respectively. In the insets, the uninfected and infected cell concentrations are respectively represented by the solid and dashed lines.Back to article page
