As it is well known, torsion abelian groups are not preserved by localization functors. However, Libman proved that the cardinality of LT is bounded by |T |א0 whenever T is torsion abelian and L is a localization functor. In this paper we study localizations of torsion abelian groups and investigate new examples. In particular we prove that the structure of LT is determined by the structure of ...

Libman-Sacks endocarditis (LSE) is the most characteristic cardiac manifestation of systemic lupus erythematosus (SLE). It is usually clinically silent but heart failure due to valvular dysfunction, secondary infective endocarditis and embolic phenomena can complicate valvular abnormalities. We present a patient with SLE and blindness due to right central retinal artery occlusion. Echocardiogra...

BACKGROUND Neuropsychiatric systemic lupus erythematosus (NPSLE) is associated with increased morbidity and mortality. METHODS We used Diffusion Tensor Imaging (DTI) to assess white matter abnormalities in seventeen NPSLE patients, sixteen SLE patients without NPSLE, and twenty age- and gender-matched controls. RESULTS NPSLE patients differed significantly from SLE and control patients in w...

Systemic lupus erythematosus (SLE) is an autoimmune disease causing inflammatory tissue damage. Multiple organ damage can ensue with renal and neurological involvement carrying the worse prognosis. In this case report we present a 10-year-old African American girl who presented with abnormal choreiform movements, headache, weight loss, and fatigue. Detailed clinical examination with laboratory ...

The energy of harmonic sections of flat bundles of nonpositively curved (NPC) length spaces over a Riemann surface S is a function Eρ on Teichmüller space TS which is a qualitative invariant of the holonomy representation ρ of π1(S). Adapting ideas of Sacks-Uhlenbeck, Schoen-Yau and Tromba, we show that the energy function Eρ is proper for any convex cocompact representation of the fundamental ...
