PURPOSE To produce animal models of Acanthamoeba keratitis and to evaluate the advantages and adaptation range of each of the three methods employed. MATERIALS AND METHODS Mice and Wistar rats in three groups of 15 rats and 15 mice each were used to establish the models. Right corneas in group A were scratched and challenged with Acanthamoeba. Those in(More)
Advanced Glycation End Products (AGEs) has been implicated in the progression of diabetic keratopathy. However, details regarding their function are not well understood. In the present study, we investigated the effects of intracellular reactive oxygen species (ROS) and JNK, p38 MAPK on AGE-modified bovine serum albumin (BSA) induced Human(More)
BACKGROUND To analyze the efficacy of selective laser trabeculoplasty (SLT) on silicone oil-induced secondary glaucoma in terms of intraocular pressure (IOP). PATIENTS AND METHODS 42 patients (42 eyes) with silicone oil-induced secondary glaucoma were selected, and SLT was performed with 360° of the trabecular meshwork. During the 12-month follow-up, the(More)
Our aim was to produce a natural, acellular matrix from porcine cornea for use as a scaffold in developing a tissue-engineered cornea replacement. Full-thickness, intact porcine corneas were decellularized by immersion in 0.5% (wt/vol) sodium dodecyl sulfate. The resulting acellular matrices were then characterized and examined specifically for completeness(More)
PURPOSE To optimise a protocol to produce an acellular porcine cornea scaffold and investigate its mechanical integrity and biocompatibility. METHODS Fresh porcine corneas were decellularised with different detergents over a range of concentrations. Morphological and histological examinations were carried out to detect the major structure of the cornea.(More)
Connective Tissue Growth Factor (CTGF) and Transforming growth factor-β1 (TGF-β1) are key growth factors in regulating corneal scarring. Although CTGF was induced by TGF-β1 and mediated many of fibroproliferative effects of TGF-β1, the signaling pathway for CTGF production in corneal scarring remains to be clarified. In the present study, we firstly(More)
Our previous studies reported that pattern recognition receptors (PRRs), including the cell surface Toll-like receptors (TLRs) and cytoplasmic NOD-like receptors (NLRs), recognize pathogen-associated molecular patterns (PAMPS) to initiate downstream signal cascades to active immunity responses. Thymic stromal lymphopoietin (TSLP) has recently emerged as a(More)
BACKGROUND To report the diagnostic features and management strategy of a rare case of Weill-Marchesani syndrome with advanced glaucoma and corneal endothelial dysfunction. CASE PRESENTATION A patient presented with advanced glaucoma with an intraocular pressure of 49 mmHg in the left eye, and subsequently received trabeculectomy to control the(More)
Acanthamoeba keratitis (AK) is a vision-threatening corneal infection that is intimately associated with contact lens use which leads to hypoxic conditions on the corneal surface. However, the effect of hypoxia on the Acanthamoeba-induced host inflammatory response of corneal epithelial cells has not been studied. In the present study, we investigated the(More)
Innate immunity is considered to be critical in the pathogenesis of fungal keratitis. Pattern recognition receptors (PRRs) recognize conserved microbial structures called pathogen-associated molecular patterns (PAMPS), thereby initiating the innate immunity. Toll-like receptors (TLRs) and nucleotide-binding oligomerization domain (NOD)-like receptors(More)
