Abstract

Background No reliable indicators of the transition to the progressive course in multiple sclerosis (MS) have been identified so far. The main clinical feature of the progressive phase of MS is usually impairment of walking. Magnetic resonance imaging and optical coherence tomography have emerged recently as promising tools to assess increasing neurodegeneration and axonal loss in disease progression in MS. Methods. Case report. Results. We report a case of progressive visual impairment as the dominant symptom in the transition to secondary progressive MS. Conclusions. Impairment of vision, together with walking and cognition, should be considered to better define the transition from relapsing/remitting to secondary-progressive MS.

Abstract

Let A be a non-trivial semiprime associative superalgebra with superinvolution. In the present note we investigate when the subspaces of symmetric elements or skew elements of A are Lie nilpotent or Lie solvable. We show that these conditions determine the algebraic structure of A. © 2012 Elsevier Inc.
