Antimicrobial photodynamic therapy and photodynamic inactivation, or killing bugs with dyes and light--a symposium-in-print

In antimicrobial photodynamic therapy, the photosensitizer (PS) in its ground singlet state absorbs light to give the excited singlet state that can transition to the long-lived triplet state. This PS triplet may undergo energy transfer (Type 2) or electron transfer (Type 1) to oxygen to form reactive oxygen species (singlet oxygen and/or hydroxyl radicals) that can kill both Gram-positive and Gram-negative bacteria and fungi. Infections in animal models can also be treated.     

Solvable Groups Satisfying the Two-Prime Hypothesis II

In this paper, we consider solvable groups that satisfy the two-prime hypothesis. We prove that if G is such a group and G has no nonabelian nilpotent quotients, then |cd G|?≤?462,515. Combining this result with the result from part I, we deduce that if G is any such group, then the same bound holds.
