CP-424391, 2-amino-N-[3aR-benzyl-2-methyl-3-oxo-2,3,3a,4,6,7-hexahydro-pyrazolo[4,3-c]pyridin-5-yl)-1R-benzyloxymethyl-2-oxoethyl]-isobutyramide, is an orally active growth hormone secretagogue currently being developed. In this study, we investigated the metabolic fate and disposition of radiolabeled CP-424391 in rats. Following 15 mg/kg single oral administration to Sprague-Dawley rats, 91% o...

AIM To determine the expression and distribution of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) in the normal human iris and ciliary body. METHODS Seven postmortem human eyes were fixed with formalin. The iris and ciliary body were dissected out and embedded in paraffin. The expression of MMPs -1, 2, 3, and 9, and TIMPs 1-4 in the iris and ciliary body was determined by a no...

BACKGROUND Primary extranodal marginal zone lymphoma (EMZL) of the uvea is a rare condition and diagnosis may be challenging. We aim to report the clinical, histopathologic and immunohistochemical findings in a case of primary EMZL with diffuse uveal involvement and focal infiltration of the trabecular meshwork. CASE PRESENTATION A 38-year-old male presented with 2-year progressive vision los...

In I882 Professor von Recklinghausen, Director of the Institute of Pathology at our University published his original work. "Ober die multiplen Fibrome der Haut und ihre Beziehung zu den multiplen Neuromen". Since that time neurofibromatosis, which bears his name, has been the subject of many reports; in addition to the cutaneous lesions characterized by multiple neuromata and cafi au lait spot...

Experimental autoimmune pigment epithelial protein-induced uveitis (EAPU) is a new type of disease that destroys the retinal pigment epithelium (RPE), and exhibits a hitherto unknown form of progressive chorioretinal dystrophy in which neuroretinal inflammatory foci are absent. The present study was aimed at studying the expression of adhesion molecules, and the kinetics of the appearance of th...

PURPOSE To evaluate the effect of pars plana filtration with multiple laser perforation of the uvea in neovascular glaucoma patients following proliferative diabetic retinopathy. METHODS In 18 eyes of 13 patients, after a fornix-based conjunctival incision, two 9 x 3 mm, thin, rectangular scleral flaps were created 3-6 mm posterior to the limbus. The remaining layers of sclera under each flap...

The potential of stem cell (SC) therapies for eye diseases is well-recognized. However, the results remain only encouraging as little is known about the mechanisms responsible for eye renewal, regeneration and/or repair. Therefore, it is critical to gain knowledge about the specific tissue environment (niches) where the stem/progenitor cells reside in eye. A new type of interstitial cell-telocy...
