The CFVAD3 is the third prototype of a continuous flow ventricular assist device being developed for implantation in humans. The pump consists of a fully shrouded 4-blade impeller supported by magnetic bearings. On either side of this suspended rotating impeller is a small clearance region through which the blood flows. The spacing and geometry of these(More)
Human ability to switch from one cognitive task to another involves both endogenous preparation without an external stimulus and exogenous adjustment in response to the external stimulus. In an event-related functional MRI study, participants performed pairs of two tasks that are either the same (task repetition) or different (task switch) from each other.(More)
OBJECTIVE To determine the prevalence and characteristics of fibromyalgia in the general population. METHODS A random sample of 3,006 persons in Wichita, KS, were characterized according to the presence of no pain, non-widespread pain, and widespread pain. A subsample of 391 persons, including 193 with widespread pain, were examined and interviewed in(More)
Small synthetic molecules termed growth hormone secretagogues (GHSs) act on the pituitary gland and the hypothalamus to stimulate and amplify pulsatile growth hormone (GH) release. A heterotrimeric GTP-binding protein (G protein)-coupled receptor (GPC-R) of the pituitary and arcuate ventro-medial and infundibular hypothalamus of swine and humans was cloned(More)
BACKGROUND AND METHODS MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) has been the standard treatment for Hodgkin's disease for almost 20 years. In a randomized, multicenter trial, we compared three regimens of primary systemic therapy for newly diagnosed advanced Hodgkin's disease in Stages IIIA2, IIIB, and IVA or IVB: (1) MOPP alone(More)
Learning curves are presented as an unbiased means for evaluating the performance of models for neuroimaging data analysis. The learning curve measures the predictive performance in terms of the generalization or prediction error as a function of the number of independent examples (e.g., subjects) used to determine the parameters in the model.(More)
The switch cost (the disadvantage of performing a new task vs. a repeated task) has been attributed to lack of preparation for the switched task or priming of the repeated task. These sources were examined by manipulating foreknowledge of task transition (repeat or switch), response-to-stimulus interval (RSI), and practice level. Regardless of(More)
The PRT1, TIF34, GCD10, and SUI1 proteins of Saccharomyces cerevisiae were found previously to copurify with eukaryotic translation initiation factor 3 (eIF3) activity. Although TIF32, NIP1, and TIF35 are homologous to subunits of human eIF3, they were not known to be components of the yeast factor. We detected interactions between PRT1, TIF34, and TIF35 by(More)
Only five of the nine subunits of human eukaryotic translation initiation factor 3 (eIF3) have recognizable homologs encoded in the Saccharomyces cerevisiae genome, and only two of these (Prt1p and Tif34p) were identified previously as subunits of yeast eIF3. We purified a polyhistidine-tagged form of Prt1p (His-Prt1p) by Ni2+ affinity and gel filtration(More)
