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 investigated in a mouse model of oxygen-...

The increase in the frequency and popularity of aesthetic filler injections is accompanied by a high risk complications, including ophthalmological sequalae. Of these, loss vision considered most dangerous and, cases, irreversible. We present case report patient who experienced acute due to suspected partial occlusion ophthalmic artery following nonsurgical rhinoplasty with hyaluronic acid inje...

Treatment of preterm human infants with high oxygen can result in disrupted lung alveolar and vascular development. Local or systemic administration of endothelial progenitor cells (EPCs) is reported to remedy such disruption in animal models. In this study, the effects of both fresh (enriched for KDR) and cultured bone marrow (BM)-derived cell populations with EPC characteristics were examined...

the hybrid molten/solid in2o3 - 30-48 wt.% bi2o3 oxide materials were studied with respect to their transport properties. the conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe dc, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. we show that the oxygen permeability of the hybrid molten/so...

introduction: oxygen is a drug and physician and nurses should be familiar with the effects and potential risks of oxygen therapy. the current study aimed to assess familiarity of physicians and nurses with various aspects of oxygen therapy. method: in this cross sectional study, the familiarity of physicians and nurses with various aspects of oxygen therapy in a teaching hospital was evaluated...

The article is devoted to the analysis of flame anchoring mechanism in test case MASCOTTE C-60 RCM2 on supercritical hydrogen/oxygen combustion at 60 bar, with transcritical (liquid) injection oxygen. simulated by means in-house parallel code HeaRT three-dimensional LES framework. cubic Peng–Robinson equation state its improved translated volume formulation assumed. Diffusive mechanisms and tra...
