OBJECTIVES To examine the prevalence of hearing loss (HL) in Union Army (UA) veterans by year, birth cohort, and occupation, and to compare Civil War pension and contemporary disability programs by examining monthly dollar awards. STUDY DESIGN A retrospective review of medical records for 17,722 UA veteran pension applicants, a subset of some 35,000 soldiers retrieved randomly from the Milita...

Hepatic lipase (HL) plays a role in the catabolism of apolipoprotein (apo)B-containing lipoproteins through its lipolytic and ligand-binding properties. We describe a potential intracellular role of HL in the assembly and secretion of VLDL. Transient or stable expression of HL in McA-RH7777 cells resulted in decreased (by 40%) incorporation of [(3)H]glycerol into cell-associated and secreted tr...

3-Hydroxy-3-methylglutaryl-CoA lyase (HL, EC 4.1.3.4) catalyses the last step of ketogenesis from leucine and fatty acids. HL deficiency in humans is one of the many inborn errors of CoA ester metabolism. By gene targeting, we created a strain of HL-deficient mice. Heterozygous HL-deficient mice are clinically normal and fibroblasts from homozygous HL-deficient embryos grow normally despite abs...

PURPOSE To design multichannel large-tip-angle kT-points and spokes radiofrequency (RF) pulses and gradient waveforms for transmit field inhomogeneity compensation in high field magnetic resonance imaging. THEORY AND METHODS An algorithm to design RF subpulse weights and gradient blip areas is proposed to minimize a magnitude least-squares cost function that measures the difference between re...

Background Radio Frequency (RF) induced heating associated with MRI is an increasing safety concern as more patients are implanted with cardiovascular devices. A standard test method (ASTM F2182) is used across the device industry to measure RF heating, but this method does not account for cooling mechanisms such as blood flow and perfusion. We hypothesize that in vivo conditions will significa...

Relevance Feedback (RF) is a technique allowing to enrich an initial query according to the user feedback in order to get results closer to the user’s information need. This paper presents a new RF method for keyword queries (content queries). It is based on the re-weighting of the original query terms plus the addition of new query terms from the content of elements jugded as relevant or non-r...

in recent years, chitosan nanoparticles have been studied widely for protein delivery. in this study, hemiscorpius lepturus (hl) venom was encapsulated in chitosan nanoparticles. the aim of the present work was to carry out a systematic study for preparing biocompatible and biodegradable nanoparticles for loading hl scorpion venom and to evaluate their potential as an antigen delivery system. i...

In this paper an accurate method is presented for determining of the device sizes in a RF circuit based on genetic algorithm (GA). HSPICE RF simulation is used for evaluating of the fitness of the circuit specifications per every iteration of the GA. Also an example for a LNA is presented for evaluating of non-dominated sorting genetic algorithm (NSGA-II) as a method of multi objective genetic ...

We for the first time propose the highly efficient method of RF and optical signal mixing based on two different architectures: the parallel-RF/serial-optics architecture characterized by all-optical mixing for sub-carrier multiplexing, and the parallel-RF/parallel-optics architecture based on the array of 12x10 GHz components with directly modulated VCSELs and 12 multimode optical fibers. The ...
