Lysophosphatidic acid (LPA) is a low-molecular-weight lipid growth factor, which binds to G-protein-coupled receptors. Previous studies have shown that LPA enhances vascular endothelial growth factor-A (VEGF-A) expression in cancer cells and promotes angiogenesis process. However, the roles of LPA in lymphatic vessel formation and lymphangiogenesis have not(More)
Achieving effective real-time voice communication over an ad hoc network of mobile wireless nodes is an important new challenge in the wireless arena and opens new directions for research in speech coding. In this paper, we review the problems and issues in supporting speech over mobile ad hoc networks and examine the role of new speech coding techniques(More)
Microarray-based pooled DNA methods overcome the cost bottleneck of simultaneously genotyping more than 100 000 markers for numerous study individuals. The success of such methods relies on the proper adjustment of preferential amplification/hybridization to ensure accurate and reliable allele frequency estimation. We performed a hybridization-based(More)
Cervical arch is a rare congenital anomaly presumed to result from persistence of the third aortic arch and regression of the normal fourth arch. Rather rare is cervical aortic arch associated with aneurysm and obstruction, with eight known cases reported. Definitive diagnosis with a noninvasive imaging modality is desirable and very important to prevent(More)

The aim of this population-based retrospective cohort study was to investigate the onset of urinary tract infection in newborns and the associated risks of childhood asthma. Children with neonatal UTI (n = 3,312) and randomly selected controls (n = 13,243) were enrolled for our analysis. We calculated the follow-up person-years for each participant from the(More)
This paper focuses on the development of a methodology within a software environment for automating the rule based implementation of specifications of integrated manufacturing information systems. The specifications are initially formulated in a naturallanguage and subsequently represented in terms of a graphical representation by the system designer. A new(More)
The aggregation kinetics of thermoresponsive core-shell micelles with a poly(N-isopropyl acrylamide) shell in pure water or in mixtures of water with the cononsolvents methanol or ethanol at mole fractions of 5 -% is investigated during a temperature jump across the respective cloud point. At the cloud point, aggregates are formed, and their growth is(More)
The impacts of various layout configuration and device dimensions on device performance are examined. The geometrical scaling issues including emitter length and emitter stripe-number scaling are used to shift simultaneously the optimum noise and optimum source impedance to a point that is close to 50 /spl Omega/. Via this method, not only is the optimal(More)
