Alterations of certain metabolite concentrations and fluxes that occur in response to viral infection are described. Host cell enzymes in the involved metabolic pathways are selected as targets for intervention; i.e., to restore metabolic flux to disadvantage viral replication, or to further derange metabolic flux resulting in “suicide” of viral-infected cells (but not uninfected cells) in order to limit viral propagation. While any of the enzymes in the relevant metabolic pathway can be selected, pivotal enzymes at key control points in these metabolic pathways are preferred as candidate antiviral drug targets. Inhibitors of these enzymes are used to reverse, or redirect, the effects of the viral infection. Drug candidates are tested for antiviral activity using screening assays in vitro and host cells, as well as in animal models. Animal models are then used to test efficacy of candidate compounds in preventing and treating viral infections. The antiviral activity of enzyme inhibitors is demonstrated.

Automatically positioning of typographical features, such as vertical stems or horizontal segments of a character, on high contrast pixel sub-component boundaries as part of a rendering process that uses separately controllable pixel sub-components of pixels to represent different portions of the character. In order to identify the typographical features of the character that are to be aligned with high contrast pixel sub-component boundaries, topology of the character is analyzed at runtime. In display devices having vertical stripes of same-colored pixel sub-components, character legibility is increased when the left edges of stems are aligned with high contrast boundaries between pixel sub-components. Processing time and resources are conserved by performing a partial, rather than a full, topological analysis of the character. For example, some font files include data structures that define the position of key control points associated with the character, thereby indicating where the stems or other typographical features are located, and the relationship between different typographical features.
