Multiple-channel detection is considered in the context of a sensor network where raw data are shared only by nodes that have a common edge in the network graph. Established multiple-channel detectors, such as those based on generalized coherence or multiple coherence, use pairwise measurements from every pair of sensors in the network and are thus directly(More)
This prospective study assessed myocardial viability in 30 patients with coronary heart disease and persistent defects despite reinjection on TI-201 single-photon computed tomography (SPECT). In each patient, three observers graded TI-201 uptake in 7 left ventricular wall segments. Gradient-echo magnetic resonance imaging in the region of the persistent(More)
Optical techniques are effective tools for diagnostic applications in medicine and are particularly attractive for the noninvasive analysis of biological tissues and fluids in vivo. Noninvasive examinations of substances via a fiber optic probe need to consider the optical properties of biological tissues obstructing the optical path. This applies to the(More)
OBJECTIVE Biomarkers reflecting the etiology and pathophysiology of inner ear diseases are limited. Evaluation of proteins in the perilymph may improve our understanding of inner ear disease. Heat shock proteins (HSP) belong to a superfamily of stress proteins and promote refolding of denatured proteins. The aim of the study was to analyze HSP in human(More)
Soybeans can be efficiently labeled with radiolabeled iron by supplying the iron via a nutrient culture medium as an iron salt or as a chelate. By using dual labeled iron and EDTA, it was determined that none of the chelator was transported to the shoots with the iron. Therefore, the use of chelated iron as the iron source in the nutrient medium should not(More)
The knowledge about the etiology and pathophysiology of sensorineural hearing loss (SNHL) is still very limited. This study aims at the improvement of understanding different types of SNHL by proteome analysis of human perilymph. Sampling of perilymph was established during inner ear surgeries (cochlear implantation, vestibular schwannoma surgeries), and(More)
