PURPOSE During corneal infection, cytotoxic Pseudomonas aeruginosa strains remain mostly extracellular, while invasive strains can enter corneal cells and replicate within them. We tested the hypothesis that ofloxacin, which easily penetrates host cell membranes, would be more effective than the less cell-permeable antibiotic tobramycin, for treatment of(More)
Lymphatic research signifies a field of rapid progression in recent years. Though lymphatic dysfunction has been found in a myriad of disorders, to date, few effective treatments are available for lymphatic diseases. It is therefore urgent to develop new experimental approaches and therapeutic protocols. The cornea offers an ideal site for lymphatic(More)
PURPOSE To determine the effects on corneal epithelial permeability and ocular response of 30 nights of continuous wear (CW) of gas permeable (GP) and silicone hydrogel (SiH) contact lenses. METHODS Ninety-one subjects successfully completed 30 days of CW of either GP (n = 42) or SiH (n = 49) contact lenses. Epithelial permeability (P(dc)) was measured by(More)
We have previously shown that antibodies to CTLA-4, an inhibitory receptor on T cells, can be effective at inducing regression of transplantable murine tumors. In this study, we demonstrate that an effective immune response against primary prostate tumors in transgenic (TRAMP) mice can be elicited using a strategy that combines CTLA-4 blockade and an(More)
PURPOSE Composed of sheets of cells detached from the underlying conjunctiva, conjunctival epithelial flap (CEF) is a recently reported phenomenon associated with contact lens wear with potential consequences for ocular health. Although CEF is generally asymptomatic, it is not known to what extent it might increase the longer-term risk of discomfort,(More)
Lymphatic research has progressed rapidly in recent years. Though lymphatic dysfunction has been found in a wide array of disorders from transplant rejection to cancer metastasis, to date, there is still little effective treatment for lymphatic diseases. The cornea offers an optimal site for lymphatic research due to its accessible location, transparent(More)
Schlemm's canal is an important structure of the conventional aqueous humor outflow pathway and is critically involved in regulating the intraocular pressure. In this study, we report a novel finding that prospero homeobox protein 1 (Prox-1), the master control gene for lymphatic development, is expressed in Schlemm's canal. Moreover, we provide a novel in(More)
PURPOSE Lymphatic research has progressed rapidly in recent years. Lymphatic dysfunction has been found in myriad disorders from cancer metastasis to transplant rejection; however, effective treatment for lymphatic disorders is still limited. This study investigates the role of angiopoietin-2 (Ang-2) in corneal inflammatory lymphangiogenesis (LG) in vivo(More)
PURPOSE We have recently provided evidence showing that luminal lymphatic valves are formed right after the onset of corneal inflammatory lymphangiogenesis (LG). The purpose of this study was to further characterize the long-term time course, spatial distribution, directional orientation, and functional implications of the valve formation in relation to(More)
In order to achieve high instruction level parallelism (ILP), designers are turning to very long instruction word (VLIW) based designs, in which different types of instructions are grouped together as bundles of 128 bits or longer. In VLIW, the added nops increase the code size, limit processor performance by the under-utilization of functional units. In(More)
