PURPOSE The efficacy of three matrix metalloproteinase (MMP) inhibitors with various selectivities (Ro-31-9790, AG3340, and DPC-A37668) was investigated in a rat model of retinopathy of prematurity, to examine the roles of MMP-2 and -9 in retinal neovascularization. The susceptibilities of MMP-2(-/-) and -9(-/-) mice to preretinal neovascularization were(More)
BACKGROUND Although both human immunodeficiency virus (HIV) infection and diarrhea are considerable problems in Cambodia, there have not been any studies to determine the history, clinical presentation, and etiology of chronic diarrhea in patients with HIV infection in Cambodia. In this article, we present a case-control study involving 40 HIV-infected(More)
PURPOSE We investigated endoglin expression in hypoxic microvascular endothelial cells and retinal endoglin expression in rats that develop experimental oxygen-induced retinopathy (OIR). We also tested neutralizing antibodies (Abs) against endoglin (anti-CD105 Ab) and VEGF (anti-VEGF Ab) either alone or in combination for efficacy against serum-induced(More)
We assessed the effect of topical ketorolac on laser-induced choroidal neovascularization (CNV), measured retinal PGE(2) and VEGF levels after laser treatment, and determined the effect of ketorolac on PGE(2) and VEGF production. Six laser burns were placed in eyes of rats which then received topical ketorolac 0.4% or artificial tears four times daily until(More)
Retinopathy of prematurity (ROP) is a potentially blinding disease affecting premature infants. ROP is characterized by pathological ocular angiogenesis or retinal neovascularization (NV). Models of ROP have yielded much of what is currently known about physiological and pathological blood vessel growth in the retina. The rat provides a particularly(More)
An independent tabulation of incidence of cutaneous malignant melanoma in Massachusetts indicates that 12% and perhaps as many as 19% of new cases of cutaneous malignant melanoma in Massachusetts are not recorded in the Massachusetts Cancer Registry, significantly more than the expected 5% (p = 0.0001). The increasing number of nonhospital medical settings(More)
PURPOSE To characterize the angiostatic effect of penetrating ocular injury and to begin to explore its mechanism, with an emphasis on the role of pigment epithelium-derived factor (PEDF). METHODS Using the rat model of oxygen-induced retinopathy (OIR), single or multiple dry needle injuries were made, penetrating the globe of one eye; the opposite eye(More)
PURPOSE PGE(2) binds to PGE(2) receptors (EP(1-4)). The purpose of the present study was to investigate the role of the EP(4) receptor in angiogenic cell behaviors of retinal Müller cells and retinal microvascular endothelial cells (RMECs) and to assess the efficacy of an EP(4) antagonist in rat models of oxygen-induced retinopathy (OIR) and laser-induced(More)
Three young women, offspring of a nonconsanguineous marriage of normal parents, manifested mild visual loss associated with a bilateral foveal dystrophy that resembled the macular involvement in juvenile sex-linked retinoschisis. Electrophysiologic and psychophysiologic tests showed less severe involvement than the gonosomal equivalent. An autosomal(More)
The primary objective of this study was to develop and evaluate new methods of analyzing laser-induced choroidal neovascularization (CNV), in order to make recommendations for improving the reporting of experimental CNV in the literature. Six laser burns of sufficient power to rupture Bruch's membrane were concentrically placed in each eye of 18 adult(More)
