In the hippocampus, two distinct forms of GABAergic inhibition have been identified, phasic inhibitory postsynaptic currents that are the consequence of the vesicular release of GABA and a tonic conductance that is activated by low ambient concentrations of extracellular GABA. It is not known what accounts for the distinct properties of receptors that(More)
In vitro gastrointestinal models, used to measure the metal(loid) bioaccessibility for site specific risk assessment, are typically operated under fasted conditions. We evaluated the hypothesis that fed conditions increase arsenic bioaccessibility on three reference soils (NIST 2711, NIST 2709, and BGS 102) and the bulk and <38 mum size fractions of a mine(More)
Observations in 14 eyes in 7 patients with sex-linked juvenile retinoschisis over a 4 to 8 year period show that the maculopathy tends to progress through a series of stages (Figs. 14, 15, 16) which are associated with increasing impairment in visual acuity. Electrical changes confirm the pathological state of the macula but suggest a pan-retinal disease.(More)
BACKGROUND The purpose of this study was to characterize the sequential development of focal and surround retinal injury and repair following transscleral diode laser to rat retina. METHODS Transscleral laser photocoagulation of the retina was induced with a diode laser (DioPexy Probe, 810 nm, 200 mW, 2 seconds) in adult Long-Evans rats. The right eye of(More)
An attempt to establish an animal model (rabbit) to study deposition and transport of cholesterol in the eye has been described. Interesting findings include the deposition of cholesterol in the choroid, sclera, and anterior cornea of rabbits fed on a high cholesterol diet. Injected intravitreal cholesterol is seen to leave through the retina, optic nerve(More)
