Article Title: Regeneration of functional nerves within full thickness collagen-phosphorylcholine corneal substitute implants in guinea pigs.
Article Snippet: Our objective was to evaluate promotion of tissue and nerve regeneration by extracellular matrix (ECM) mimics, using corneal implantation as a model system.. Porcine type I collagen and 2-methacryloyloxyethyl phosphorylcholine (MPC) were crosslinked using 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide (EDC) and N-hydroxysuccinimide (NHS) and moulded into appropriate corneal dimensions to serve as substitutes for natural corneal ECM.. These were implanted as full thickness grafts by penetrating keratoplasty into the corneas of guinea pigs after removal of the host tissue, and tracked over eight months, by clinical examination, slit-lamp biomicroscopy, and esthesiometry.

Article Title: Melanopsin expression in the cornea
Article Snippet: .. Electrical activity was amplified (AC preamplifier NL 103; Digitimer, Welwyn, UK), filtered (high pass cutoff at 5 KHz, low pass cutoff at 150 Hz; filter module NL 125; Digitimer), transferred at 20 KHz to a PC with a CED micro-1401 mk II acquisition system (Cambridge Electronic Design, Cambridge, UK), and analyzed with the indicated software (Spike 2 software v8.0; also from Cambridge Electronic Design). .. During the search for an active unit in the isolated cornea preparation, illumination was provided by a Volpi light source (Volpi Intralux 5000-1, Volpi AG, Schlieren, Switzerland), with the fiber optic beam directed obliquely to the corneal surface.

Article Title: Corneal sensory nerve activity in an experimental model of UV keratitis.
Article Snippet: METHODS.. In anesthetized animals, one eye was exposed to 254 nm UV-C radiation (500–1000 mJ/cm), excised 24 to 48 hours later and superfused in vitro.. Nerve impulse activity was recorded in ciliary nerve filaments or in corneal sensory terminals of intact and UV-irradiated eyes.

Article Title: Changes in sensory activity of ocular surface sensory nerves during allergic keratoconjunctivitis.
Article Snippet: Peripheral neural mechanisms underlying the sensations of irritation, discomfort, and itch accompanying the eye allergic response have not been hitherto analyzed.. We explored this question recording the changes in the electrical activity of corneoconjunctival sensory nerve fibers of the guinea pig after an ocular allergic challenge.. Sensitization was produced by i.p. ovalbumin followed by repeated application in the eye of 10% ovalbumin on days 14 to 18.
