BACKGROUND Tight junctions play a critical role in tubular function. In mammalian kidney, the transepithelial electrical resistance and the complexity of the tight junction increase from the proximal to the collecting tubule. The differential expression of three tight junction proteins, ZO-1, ZO-2, and occludin, along isolated rabbit renal tubules is(More)
PURPOSE In ischemic proliferative retinopathies, Müller glial cells (MGCs) acquire migratory abilities. However, the mechanisms that regulate this migration remain poorly understood. In addition, proliferative disorders associated with enhanced activities of matrix metalloproteinases (MMPs) also involve insulin-like growth factor (IGF)-1 participation.(More)
BACKGROUND Permeability properties of mammalian nephron are tuned during postnatal maturation. The transepithelial electrical resistance (TER) and complexity of tight junctions (TJs) vary along the different tubular segments, suggesting that the molecules constituting this structure change. We studied the differential expression of occludin and several(More)
At least seven parameters have been described for the measurement of patellofemoralmalalignment on CT scanning; three of which measure lateral patellar tilt, two lateral patellar shift and two femoral trochlear dysplasia. We studied 22 knees in 18 patients complaining of patellofemoral pain in order to investigate the reproducibility of these methods. CT(More)
PURPOSE To investigate whether commonly used vasodilating drugs ameliorate angiogenesis in experimental retinopathy of prematurity (ROP), and to study the response of these drugs to different growth factors. METHODS We used a rat and mouse model of oxygen-induced ischemic retinopathy. Animals were treated with nimodipine, gingko-biloba and dipyridamole(More)
Panretinal photocoagulation (PRP) reduces the incidence of severe visual loss in proliferative diabetic retinopathy (PDR). The aim of the study was to determine the effect of PRP on the activity of matrix metalloproteinase-2 (MMP-2) and MMP-9, and also on the alpha(2)-Macroglobulin (alpha(2)M) proteolytic state in the vitreous of eyes with PDR. Vitreous(More)
PURPOSE To compare the ocular comfort of two ophthalmic anti-allergic agents: olopatadine hydrochloride 0.1% and ketotifen fumarate 0.05%. SUBJECTS AND METHODS In a double-masked, multi-centered, randomized trial, 80 subjects were asked to make a 'forced choice' based on ocular comfort between one drop of olopatadine hydrochloride 0.1% instilled in one(More)
The low-density lipoprotein receptor-related protein-1 (LRP-1) is a high-molecular weight receptor of the LDL receptor gene family. Its ability to bind and internalize both proteinases and proteinase-inhibitor complexes from the extracellular space suggests that it has a major role in modulating uncontrolled retinal cell proliferation. In order to test this(More)
PURPOSE The effect of a pharmacist-managed collaborative drug therapy agreement (CDTA) on diabetes mellitus (DM) management in an outpatient setting is evaluated. METHODS Patients with DM were referred by physicians to the pharmacist for either education or clinical management of DM under the CDTA. A retrospective chart review was conducted between(More)
Autoimmunity plays an important role in the development of uveitis. The uveitis are linked to Th1 or Th2 lymphocyte activation. We studied 41 patients with uveitis, divided into autoimmune uveitis (n = 32) and infectious uveitis (n = 9), 30 normal controls, and 20 asthmatic atopic without ocular diseases. The infectious uveitis patients were separated into(More)
