PURPOSE To investigate the effect of brimonidine on the retinal ganglion cell survival in an optic nerve crush model. DESIGN Experimental animal study. METHODS Twenty-four Sprague-Dawley rats were divided into a study group of eight animals receiving intraperitoneal injections of brimonidine (1 mg/kg) and into a control group of 12 animals receiving(More)
PURPOSE To examine the effect of intraocularly produced glucagon-like peptide-1 (GLP-1) on the survival rate of retinal ganglion cells in an optic nerve crush model. METHODS Forty-one Sprague--Dawley rats were divided into a study group (21 animals) in which 4 beads with 3000 genetically modified cells to produce GLP-1 were intravitreally implanted into(More)
PURPOSE To investigate the effect of ginkgo biloba on the retinal ganglion cell survival in a rat optic nerve crush model. METHODS Twenty-four Sprague-Dawley rats were divided randomly into a study group of 12 animals receiving intraperitoneal injections of ginkgo biloba and a control group of 12 animals receiving intraperitoneal saline injections.

Network security is one of the most important issues in mobile sensor networks (MSNs). Networks are particularly vulnerable in hostile environments because of many factors, such as uncertain mobility, limitations on computation, and the need for storage in mobile nodes. Though some location-based security mechanisms can resist some malicious attacks, they(More)
