The preference of adult female rats for aspartame (L-asparty L-phenylalamine methyl ester) was measured using 24 hr/day and 30 min/day two bottle preference tests. At aspartame concentrations that humans find sweet (0.0125% to 0.05%) the rats failed to prefer aspartame to water. At higher concentrations (0.1% to 1.0%) half (n = 11) of the rats tested(More)
OBJECTIVES The goals were to determine the prevalence of community-acquired methicillin-resistant Staphylococcus aureus colonization in patients with atopic dermatitis and to determine whether suppression of S aureus growth with sodium hypochlorite (bleach) baths and intranasal mupirocin treatment improves eczema severity. METHODS A randomized,(More)
We examined the processes of cortical activation and deactivation of the fetal brain during spontaneous sleep state transitions and during central nervous processing of vibroacoustic stimulations (VASs) using nonlinear analysis of the electrocorticogram (ECoG). Tests of nonlinearity and a random shuffling routine revealed deterministic and nonlinear(More)
40 Navy subjects practiced a three-dimensional tracking task in two positions (the apparatus either in front of,, or above, the subject) under distributed and massed practice schedules to determine the effects of these variables on acquisition of skill. Distributed and massed practice were defined in terms of trial (4 1/2 and 9 min.) and session (1 and 2(More)
