Department of Radiology, University of Chicago, IL 60637, USA While CT, MRI, PET, SPECT and ultrasound have their well-defined roles for medical imaging, over the past decade multimodality systems, such as PET–CT and PET–MRI scanners, have become increasingly popular for sequential or contemporaneous data acquisition. However, these paired modalities impose limitations that may compromise our u...

Genome-scale metabolic network models can be reconstructed for well-characterized organisms using genomic annotation and literature information. However, there are many instances in which model predictions of metabolic fluxes are not entirely consistent with experimental data, indicating that the reactions in the model do not match the active reactions in the in vivo system. We introduce a meth...

BACKGROUND The aims of this study were to a) compare the lactate measurement of a Point of Care (POC) handheld device to near patient blood gas analysers, and b) determine the differential reporting times between the analysers. METHODS A two-staged study; method comparison and prospective observational stages, was conducted. For the first stage, blood samples were analysed on the i-STAT handh...

The current solar cycle minimum seems to have unusual properties that appear to be related to weak solar polar magnetic fields. We investigate signatures of this unusual polar field in the ecliptic near–Earth interplanetary magnetic field (IMF) for the STEREO period of observations. Using 1 AU OMNI data, we find that for the current solar cycle declining phase to minimum period the peak of the ...

Coledam DHC, Paludo AC, Oliveira AR, Dos-Santos JW. Dynamic exercise versus tag game warm up: the acute effect on agility and vertical jump in children. J. Hum. Sport Exerc. Vol. 7, No. 1, pp. 243-253, 2012. Although dynamic and stretching exercises have been widely investigated, there is little information about warm up performed by tag games. Thus, the purpose of the present study was to veri...

In recent years, mobile robots are expected to perform various tasks in general environments such as nuclear power plants, large factories, welfare care facilities and hospitals. However there are narrow spaces with vertical gaps made by two horizontal floors in such environments and it is difficult for general car-like vehicles to run around there. Generally, the mobile robots are required to ...

The construct and concurrent validity of the Thera-Band Perceived Exertion Scale for Resistance Exercise with elastic bands (EB) was examined. Twenty subjects performed two separate sets of 15 repetitions of both frontal and lateral raise exercise over two sessions. The criterion variables were myoelectric activity and heart rate. One set was performed with an elastic band grip width that permi...
