PURPOSE To evaluate whether systemically injected bone marrow-derived mesenchymal stem cells (MSCs) can be incorporated into neuroretinal tissues and play an important role in retinal wound healing in the laser-induced retinal trauma model. METHODS Retinotomies were made by applying an Nd:YAG laser to rat retina. On the first day after the injuries, cell suspensions that were obtained from th...

Pitcher plants of the genus Nepenthes efficiently trap and retain insect prey in highly specialized leaves. Besides a slippery peristome which inhibits adhesion of insects they employ epicuticular wax crystals on the inner walls of the conductive zone of the pitchers to hamper insect attachment by adhesive devices. It has been proposed that the detachment of individual crystals and the resultin...

PURPOSE To evaluate the causes of retinal detachment after silicone oil removal, to define possible risk factors and the anatomical and functional prognosis of this complication. METHODS 112 eyes that underwent silicone oil removal were included. The group of eyes with retinal detachment after oil removal (18/112 eyes, 16.1%) was compared with the group with no postoperative retinal detachmen...

A series of 54 non-myopic aphakic eyes with no signs of posterior vitreous detachment and 63 non-myopic aphakic eyes with various stages of posterior vitreous detachment was followed-up for a period of 6 months to 6 years. Over half of the eyes with no vitreous detachment when first examined developed various stages of posterior vitreous detachment during the follow-up period; in 10 eyes this w...

The Greater Caucasus (GC) Mountains within the central Arabia-Eurasia collision zone are an archetypal example of a young collisional orogen. However, mechanisms driving rock uplift and forming topography range controversial, with recent provocative suggestions that western GC is strongly influenced by isostatic response to slab detachment, whereas eastern half has grown through shortening crus...

Introduction: Posterior segment retained Intraocular foreign body (IOFB) management is challenging. Facility of pars plana vitrectomy (PPV) and availability well trained vitreo retina surgeons are the basic need to accomplish this work. Encircling band provide permanent 360° support close anterior retinal break prevent traction on retina. The objective study analyse clinical characteristics pre...

Cell therapies require the in vitro expansion of adherent cells such as mesenchymal stromal cells (hMSCs) in bioreactor systems or other culture environments, followed by cell harvest. As hMSCs are strictly adherent cells, cell harvest requires cell detachment. The use of hMSCs for cell therapy requires GMP production in accordance with the guidelines for advanced therapeutic medical products. ...

PURPOSE To determine the risk of new retinal tear or detachment following cataract surgery in eyes that had undergone successful repair of phakic retinal tear or detachment. METHODS A computerized search of records of patients evaluated at the Barnes Retina Institute from 1990 to 2000 for a diagnosis of phakic retinal tear or detachment was accomplished. The records of successfully treated pa...
