Intravenous admixtures containing potassium collected from three hospital pharmacies were analyzed for compounding accuracy, sterility and pyrogenicity. The study was performed in two stages. During stage I, pharmacists and technicians were not informed of the study, but during stage II they were informed. In each stage 10 samples were collected from each(More)
OBJECTIVE Our objective was to evaluate whether microalbuminuria predicts myocardial infarction (MI) in a Mexican population. METHODS The study was a prospective, population-based cohort. Baseline examination was carried out in 1989; the first follow-up in 1993 and the second in 1997. All men and non-pregnant women between 35 and 64 years of age at the(More)
As field programmable gate array (FPGA) technology has steadily improved, FPGAs have become viable alternatives to other technology implementations for high-speed classes of digital signal processing (DSP) applications. In particular , radar front-end signal processing, an application formerly dominated by custom very large scale integration (VLSI) chips,(More)
recommendations are those of the author and are not necessarily endorsed by the United States Air Force. Abstract Historically, most radar sensor array processing has been implemented using dedicated and specialized processing systems. This approach was necessary because the algorithm computation requirements were several orders of magnitude higher than any(More)
Despite the wide availability of antiretroviral drugs, more than 250,000 infants are vertically infected with HIV-1 annually, emphasizing the need for additional interventions to eliminate pediatric HIV-1 infections. Here, we aimed to define humoral immune correlates of risk of mother-to-child transmission (MTCT) of HIV-1, including responses associated(More)
Many radar sensor systems demand high performance front-end signal processing. The high processing throughput is driven by the fast analog-to-digital conversion sampling rate, the large number of sensor channels, and stringent requirements on the filter design leading to a large number of filter taps. The computational demands range from tens to hundreds of(More)
Young and elderly participants performed on a series of 12 sustained activities (3 minutes each) under either incidental or intentional memory conditions regarding subsequent recall of those activities. Half of the activities were primarily motor in nature, half primarily cognitive. A significant overall age deficit was found for recall. Most important, in(More)
OBJECTIVE To determine the molecular basis of phenylketonuria (PKU) and related hyperphenylalaninemia (HPA) and to establish correlations between phenylalanine hydroxylase (PAH) genotypes and biochemical and clinical phenotypes in an ethnically diverse US population, PAH genotypes were determined in 35 patients with PKU or HPA and 1 carrier from the Medical(More)
The organization, function, and results of a total parenteral nutrition (TPN) team consisting of a surgical staff physician, a senior surgery resident, a nurse and a pharmacist are described. The TPN team has treated 160 patients. The incidence of septicemia as a complication of TPN has been less than 1% and the rate of serious metabolic derangements of TPN(More)
