OBJECTIVE AND IMPORTANCE Homozygous Southeast Asian alpha-thalassemia mutation (--(SEA)/--(SEA)) results in deletion of all alpha-globin genes (alpha(0)-thalassemia). Since all alpha-globin chains are absent, hemoglobin F cannot be synthesized, and hemoglobin Bart's becomes the dominant fetal hemoglobin. Hemoglobin Bart's is a γ tetramer with a very high(More)
The study's aim was to assess a broad range of declarative and nondeclarative memory functions in schizophrenia to identify areas of impairment versus relative preservation. Participants included 40 schizophrenia outpatients and 30 demographically comparable community residents. All participants were administered a battery assessing declarative memory(More)

Abusive head trauma (AHT) is the leading cause of morbidity and mortality among abused children, yet the neuroanatomical underpinnings of AHT outcome is incompletely understood. The aim of this study was to characterize white matter (WM) abnormalities in infants with AHT using diffusion tensor imaging (DTI) and determine which microstructural abnormalities(More)
