The development of a macular hole is relatively common in retinal dystrophies eligible for gene therapy such as choroideremia. However, the subretinal delivery of gene therapy requires an uninterrupted retina to allow dispersion of the viral vector. A macular hole may thus hinder effective gene therapy. Little is known about the outcome of macular hole surgery and its possible beneficial and/or...

OBJECTIVE We analyzed the clinical and radiologic features of posterior apophyseal ring separation (PARS) with lumbar disc herniation and suggest the proper management options according to the PARS characteristics. METHODS We reviewed case series of patients with PARS who underwent surgery of lumbar disc herniation. Preoperative symptoms, neurologic status, Body Mass Index, preoperative and p...

PURPOSE To evaluate the incidence, clinical features, and outcomes of macular hole formation after pars plana vitrectomy with internal limiting membrane peeling for the management of epiretinal membrane. METHODS Retrospective consecutive chart review of 423 cases. RESULTS Eleven subjects developed postoperative macular holes (incidence 2.6%; 95% confidence interval, 1.5-4.6%). Two of the 11...

the permeability is a main property of oil reservoirs that shows the ability of rocks in the conduct of fluids such as oil, water and gas through the pore spaces of reservoir. the determination of the permeability is a crucial task in reserve estimation, production and development of oil reservoirs. due to this, an accurate estimate of such important reservoir rock parameter should not be made ...

Proteinase-activated receptors (PARs) are a four-member family of G protein-coupled defined by their irreversible proteolytic mechanism activation. PARs have emerged as important regulators various physiological responses and implicated in numerous pathological conditions. Importantly, PAR1 PAR4 critical platelet function, while PAR2 is well established driver inflammatory responses. PAR-target...
