Migration and differentiation of immature neurons in the retina and optic tectum were studied using retrograde transport of DiI and immunocytochemistry. The results demonstrate that many of these cells migrate via a method of perikaryal translocation. DiI was applied to the optic nerves or tecta in fixed chick embryos (Embryonic Days 4-10); 1-2 months later(More)
Neurogenesis, migration and maturation of ganglion cells in the posterior pole of chick retina have been studied using embryonic incorporation of [3H]thymidine, immunocytochemistry and retrograde labeling. Unlike previous studies, we have examined the neurogenesis of independently identified ganglion cells that have survived the period of naturally(More)
To analyze microvascular changes, angiograms and microscopic sections of the lung were prepared from 12 patients dying after severe adult respiratory distress syndrome (ARDS) of diverse cause. Anatomic features of the precapillary arterial bed were morphometrically assessed and related to the duration of acute lung injury. In intra-acinar arteries, medial(More)
PARKER, JOHN C., AND ROGER L. SNOW. Influence of external A TP on permeability and metabolism of dog red blood cells. Am. J. Physiol. 223(4) : 888-893. 1972.-Dog red blood cells undergo a rapid increase in Na-K permeability and an alteration in physical properties when exposed to external ATP in concentrations greater than 0.1 mM. The effect is reversible(More)
Here we present the algorithms and extensions that produced our successful Othello-playing program, which finished among the top five programs of this year’s Othello tournament. Specifically, we discuss a variety of search algorithms and extensions, as well as our algorithms for adaptive timemanagement, our efficient ‘bit board’ data structure, our features(More)
