We report temperature-dependent excited-state lifetime measurements on [Ru(bpy)(2)dppz](2+) in both protic and aprotic solvents. These experiments yield a unifying picture of the excited-state photophysics that accounts for observations in both types of solvent. Our measurements support the notion of bpy-like and phz-like states associated with the dppz(More)
OBJECTIVES The objective of this study was to determine the relationship between HIV infection and tooth loss. Based on periodontal reports, we hypothesize HIV+ patients experience greater tooth loss than systemically healthy patients. STUDY DESIGN This was a retrospective cross-sectional chart study involving 193 HIV+ patients and 192 controls matched on(More)
