The patient is a 74-year-old white woman with a 2-month history of dysphagia. Evaluation with barium swallow first identified an extrinsic compression in the upper to middle third of the esophagus. Magnetic resonance imaging (MRI) showed the mass extended to the midline posteriorly and was compressing the esophagus.

Obstetrics and Gynecology Clinics of North America, 1992
With the emergence of an understanding of the processes at the cellular level that control the differentiated functions of tissues and eventually manifest as the developmental sequence in the whole animal, it is possible to describe pubertal aberrations in terms that are at once grounded in fundamental concepts of cellular biology and of practical ...

Abstract Although great empasis is placed on providing a satisfactory conduit for regeneration of peripheral axons after nerve repair, the quality of functional restoration is influenced as much by the quality as the quantity of axonal

THE SPHERICAL ABERRATION OF THE EYE
Optometry and Vision Science, 1949The spherical aberration of the eye was measured by placing a series of centered annular apertures over the eye pupil, and determining the optimum spectacle correction for each aperture. A “double star” was used as a test object. Accommodation was controlled by reflecting a second test object into the field of view. The three eyes examined had positive

Ophthalmic and Physiological Optics, 2005
Abstract It has been suggested that high levels of axial aberration or specific patterns of peripheral refraction could play a role in myopia development. Possible mechanisms involving high levels of retinal image blur caused by axial aberrations include form deprivation through poor retinal image quality in distance vision, enhanced ...
