Rigid body mechanics with computer data acquisition and analysis techniques were used to determine the three-dimensional motions of any point on the tibial component of a total knee arthroplasty. Three stem configurations were compared: (1) no stem; (2) short stem (40 mm); and (3) long stem (75 mm). In addition, three loading conditions were analyzed for(More)
Subfractionation of the total low density Sf 4–105, the low density Sf 4–20 and high density plasma (or serum) lipoproteins has been accomplished using a cumulative flotation rate procedure. Fractionation employs nonlinear salt gradients and high performance swinging bucket rotors. Subfractionation of the total low density lipoproteins with minimal(More)
A method involving three computer programs is described for characterizing the major component of the Sf 0–12 low-density lipoprotein class by its Sf rate, hydrated density and molecular weight. All necessary information is obtained from a standard low and high-density lipoprotein ultracentrifugal analysis. Moving-boundary flotation rates are measured in(More)
Smith-Magenis syndrome (SMS) is a neurodevelopmental disorder associated with intellectual disability, sleep disturbances, early onset obesity and vast behavioral deficits. We used the Behavior Problems Inventory-01 to categorize the frequency and severity of behavioral abnormalities in a SMS cohort relative to individuals with intellectual disability of(More)
A simplified method for the analysis of both the glyceride-rich Sf 20-1 O5 and the cholesterol-rich St 0-20 lowdensity lipoproteins is presented. It consists of serum lipoprotein fractionation by preparative ultracentrifugation and subsequent quantitative analysis by refractometry. Comparison of this technique with the technically more difficult analytic(More)
