AIM To determine the sub-macular Bruch's membrane (BrM) macrophage count and the choroidal and BrM macrophage immunophenotype in normal eyes and in eyes with early and advanced age-related macular degeneration (AMD). METHODS BrM macrophages were counted in 125 human eyes (normal, normal aged, early AMD and geographical atrophy), and CD68 and inducible… (More)
Wireless power, when coupled with miniaturized implantable electronics, has the potential to provide a solution to several challenges facing neuroscientists during basic and preclinical studies with freely behaving animals. The EnerCage system is one such solution as it allows for uninterrupted electrophysiology experiments over extended periods of time and… (More)
Cells that bound antibody to the astrocyte intermediate filament protein were cultured from adult rat sciatic nerve. The antigen was intracellular, finely filamentous, and formed perinuclear caps in response to colchicine, all properties of intermediate filaments. Cytoskeletal proteins of these cultures were separated by SDS-gel electrophoresis, transferred… (More)
This article provides comments of three conference panel members on the analyses of the productivity adjustment used in the Medicare Economic Index (MEI), and on exploratory estimates of physician-specific productivity measures. Each has a different background and perspective.
