This investigation extended work on the Wechsler Adult Intelligence Scaled-Revised (WAIS-R) to the WAIS-III by determining how allotments of scaled-score points change with age, and to evaluate WAIS-III performance in terms of the Horn-Cattell constructs of crystallized and fluid intelligence. The age norms for the 14 individual WAIS-III subtests indicate(More)
Parasites causing malaria need to migrate in order to penetrate tissue barriers and enter host cells. Here we show that the actin filament-binding protein coronin regulates gliding motility in Plasmodium berghei sporozoites, the highly motile forms of a rodent malaria-causing parasite transmitted by mosquitoes. Parasites lacking coronin show motility(More)
Psychologists estimated "true IQs" or "effective intelligence" from WISC profiles that varied for ethnicity (black, Mexican-American, or white), social class (lower or middle), profile (three scatter patterns), and direction of Verbal-Performance Scale discrepancy. Psychologists gave higher IQ estimates to black and Mexican-American children's profiles than(More)
The biological function of the post-translational modification hypusine in the eukaryotic initiation factor 5A (EIF-5A) in eukaryotes is still not understood. Hypusine is formed by two sequential enzymatic steps at a specific lysine residue in the precursor protein EIF-5A. One important biological function of EIF-5A which was recently identified is the(More)
During the clinically silent liver stage of a Plasmodium infection the parasite replicates from a single sporozoite into thousands of merozoites. Infection of humans and rodents with large numbers of sporozoites that arrest their development within the liver can cause sterile protection from subsequent infections. Disruption of genes essential for liver(More)
Using histochemically demonstrated acetylcholinesterase activity and (14)C-2-deoxyglucose uptake as the respective indices, a study was set up to determine whether cerebral (hippocampal) metabolism was stimulated by a cholinergic agonist and/or inhibited by a cholinergic antagonist. For this 36 12-month-old (adult) and 48 27-month-old (aged) Fischer 344(More)
Hardy, Welcher, Mellitis, and Kagan altered standard WISC administrative and scoring procedures and, from the resulting higher subtest scores, concluded that IQs based on standardized tests are inappropriate measures for inner-city children. Careful examination of their study reveals many methodological inadequacies and problematic interpretations. Three of(More)
