Detailed statistical rate calculations combined with electron capture theory and kinetic modeling for the electron attachment to SF(6) and detachment from SF(6)(-) [Troe et al., J. Chem. Phys. 127, 244303 (2007)] are used to test thermionic electron emission models. A new method to calculate the specific detachment rate constants k(det)(E) and the electron energy distributions f(E,epsilon) as f...

purpose: to evaluate the underlying causes of rhegmatogenous retinal detachment (rrd) in eyes operated for this reasion. methods: out of 1473 patients who underwent retinal detachment surgery, records of 369 patients were randomly selected and evaluated for the types of retinal breaks, the underlying disorders, and location of breaks. results: fifty-two percents of patients were less than 50 ye...

AIM To determine the efficacy and safety of perfluorocarbon liquid as a short term postoperative tamponade in patients with retinal detachment from giant retinal tears. METHOD A retrospective consecutive case series of patients with retinal detachment from giant retinal tears who underwent vitrectomy using perfluorocarbon liquid as a short term postoperative internal tamponade. The perfluoroc...

OBJECTIVE To study the complications after Descemet's stripping automated endothelial keratoplasty (DSAEK). METHODS Retrospective study of 75 eyes in 67 patients with Fuchs' endothelial dystrophy or bullous keratopathy operated on in the Instituto de Oftalmología La Arruzafa from March, 2007 until March, 2010. Phacoemulsification and IOL implantation was involved in 30 cases. All surgical and...

The ability of Candida albicans to form biofilms is a virulence factor that allows tissue attachment and subsequent infection of host tissues. Fungal biofilms have been particularly well studied, however the vast majority of these studies have been conducted under static conditions. Oral biofilms form in the presence of salivary flow, therefore we developed a novel flow system used for real-tim...

Retinal detachment is the physical separation of the retina from the retinal pigment epithelium. It occurs during aging, trauma, or during a variety of retinal disorders such as age-related macular degeneration, diabetic retinopathy, retinopathy of prematurity, or as a complication following cataract surgery. This report investigates the role of fibulin 2, an extracellular component, in retinal...

AIM To evaluate surgery results and establish prognostic factors that predicted final functional (good or poor vision) and anatomic (final retinal detachment) outcome in open eye injury involving the posterior segment managed with pars plana vitrectomy. METHODS Medical records of 52 consecutive patients with open eye injury involving the posterior segment were retrospectively reviewed. Specif...

Rhegmatogenous retinal detachment (RRD) is an important cause of visual impairment and one of the most common ocular emergencies threatening vision. Timely surgical intervention is crucial to prevent permanent visual loss. The fundamental principles used in the surgical management of RD are the identification and subsequent closing of all retinal breaks, and relieving vitreous traction on the r...

Biofilm detachment under a dynamic change in shear stress was monitored using Focused Beam Reflectance Measurements (FBRM, LASENTEC®) and mass fractionation. An annular reactor was used to grow biofilm with glucose as substrate. Changing the rotational speed on the inner cylinder of the annular reactor from 150 RPM to 420 RPM induced a step increase in shear stress. It was observed that the rat...
