Hour-glass stricture of the stomach and iron deficiency.
THE object of this note is to put forward the hypothesis that hour-glass stricture of the stomach occurs in persons with a chronic simple gastric ulcer of the lesser curvature, because these persons also have chronic iron deficiency, and that the stricture would not occur without the co-existence of the iron deficiency. Seven cases are described. An association with Plummer-Vinson stricture of ...
متن کاملOn hour-glass sector zoning in clinopyroxene
The observations of hour-glass sector zoning from four selected clinopyroxenes in undersaturated lavas best fit a model in which the sector zoning is formed due to a structural requirement in a growth direction normal to {IOO} where a high concentration of silicate units, required to build the silicate chains, is unsatisfied. In these sectors AI substitutes for Si, the charge balance being main...
متن کاملRemarks on microperiodic multifunctions
It is well known that a microperiodic function mapping a topological group into reals, which is continuous at some point is constant. We introduce the notion of a microperiodic multifunction, defined on a topological group with values in a metric space, and study regularity conditions implying an analogous result. We deal with Vietoris and Hausdorff continuity concepts.Stability of microperiodi...
متن کاملRemarks on Distance-Balanced Graphs
Distance-balanced graphs are introduced as graphs in which every edge uv has the following property: the number of vertices closer to u than to v is equal to the number of vertices closer to v than to u. Basic properties of these graphs are obtained. In this paper, we study the conditions under which some graph operations produce a distance-balanced graph.
متن کاملHour Glass Constriction in Advanced Carpal Tunnel Syndrome
BACKGROUND Compressive neuropathy of median nerve is relatively common but development of an hourglass like constriction is a rare phenomenon. The purpose of this study is to show morphologic changes of median nerve in advances carpal tunnel syndrome. METHODS Eighty patients with thenar atrophy, anesthesia and paresthesia of first, second and third finger and severe changes of EMG-NCV were ch...
