PURPOSE To compare the intraoperative and short-term postoperative outcomes of cataract surgery performed with torsional mode and conventional ultrasound mode using the Infiniti Vision System (Alcon Laboratories). SETTING Cataract Service, Zhongshan Ophthalmic Center, Sun-Yat-Sen University, Guangzhou, China. METHODS In this randomized comparative(More)
Diabetic retinopathy is characterized by pathological retinal neovascularization. Accumulating evidence has indicated that high levels of circulating endothelial progenitor cells (EPCs) are an important risk factor for neovascularization. Paradoxically, the reduction and dysfunction of circulating EPCs has been extensively reported in diabetic patients. We(More)
BACKGROUND Higher-order aberrations and contrast sensitivity were evaluated in patients who underwent phacoemulsification cataract extraction followed by implantation of aspherical, monofocal or multifocal intraocular lens (IOL) replacements. METHODS In this comparative trial, 124 patients with an average age of 66.8+/-5.2 years and their 124 eyes were(More)
Cell therapy is a promising approach for the treatment of refractory ocular disease. This study investigated the efficacy of mesenchymal stromal cells (MSCs) for the treatment of dry eye associated with chronic graft-versus-host disease (cGVHD) and assessed the immunomodulatory effects of MSCs on regulatory CD8(+)CD28(-) T lymphocytes. A total of 22(More)
PURPOSE. To evaluate the role of nerve growth factor (NGF) in retinal neovascularization in an oxygen-induced retinopathy (OIR) model. METHODS. The OIR model was established in C57BL/6J mice. NGF mRNA expression in retina was measured by quantitative real-time PCR. NGF expression in protein levels was evaluated by ELISA and immunostaining with NGF antibody.(More)
BACKGROUND Systemic sclerosis (SSc) is characterized by excessive fibrosis and obliterative vascular lesions. Abnormal TGFbeta activation is implicated in the pathogenesis of SSc. Aberrant TGFbeta/Smad signaling can be controlled by stabilization of microtubules with paclitaxel. METHODS AND FINDINGS SSc and healthy human skin biopsies were incubated in(More)
Interleukin-1β (IL-1β) is a potent proinflammatory cytokine that plays a critical role in initiating immunoinflammatory responses. In this study, we generated recombinant mouse IL-1β and anti-mouse IL-1β polyclonal antibodies to examine the effect of IL-1β on experimental autoimmune uveoretinitis (EAU), a mouse model for T cell-mediated eye autoimmune(More)
Toll-like receptors (TLRs) are pattern-recognition receptors and have a critical role in both innate and adaptive responses to tissue injury. Our previous study showed that wound healing was impaired in TLR3-deficient mice. In this study, we investigated the capacity of the TLR3 agonist polyriboinosinic-polyribocytidylic acid (poly(I:C)) to promote the(More)
PURPOSE To compare the gene expression profile of trabecular meshwork (TM) and Schlemm's canal (SC) primary cultures and to identify promoters for targeting gene expression to specific cells in the outflow pathway. METHODS The differential gene expression profile of four human TM and three SC primary cultures was analyzed by gene microarrays (Affymetrix,(More)
The proliferation and epithelial-mesenchymal transition (EMT) of retinal pigment epithelium (RPE) cells are the major pathological changes in development of proliferative vitreoretinopathy (PVR), which leads to severe visual impairment. Histone deacetylases (HDACs)-mediated epigenetic mechanisms play important roles in controlling various physiological and(More)
