UNLABELLED Based on his clinical observations the "red dot sign" and hyperemic flare, Behan has advocated the superior vascularity of the island flap design for at least 2 decades. The aim of this study was to determine whether (1) surgical islanding of a flap alters the vascularity or blood supply of the flap and (2) these changes in blood supply explain Behan's clinical observations of "red d...

An error was introduced during the typesetting process. In the fourth line of Equation 13, there should be no dot above the 'T ' to the right of the approximate equality sign. The corrected line should be: % ð1Þ

Cryptococcus neoformans is a prevalent human fungal pathogen that must survive within various tissues in order to establish a human infection. We have identified the C. neoformans Rim101 transcription factor, a highly conserved pH-response regulator in many fungal species. The rim101 multiply sign in circle mutant strain displays growth defects similar to other fungal species in the presence of...

OBJECTIVES In this study we define the probability of vascular abnormality in the middle cerebral artery (MCA) territory according to the extent of ischaemic change seen using computed tomography (CT). We assessed the sensitivity and specificity of the hyperdense middle cerebral artery (HMCA) and the "dot" sign using magnetic resonance angiography (MRA). METHODS Patients presenting with ischa...

A 59-year-old man developed right hemiplegia and total aphasia. His National Institute of Health Stroke Scale score was 27. Serial multi-detector row non-contrast computed tomography (CT) with multiple planar reconstruction (MPR) revealed a hyperdense middle cerebral artery (MCA) sign in the left MCA (Picture A and B, arrow), and a diagnosis of acute ischemic stroke was made. Alteplase (0.6 mg/...

Performance of three-dot bisection was determined as a function of orientation for a variety of feature separations and field meridians at eccentricities of 0-10 deg for two observers. The dot stimuli and separations were scaled in size to compensate for eccentricity. The precision of three-dot bisection was found to depend on the direction of test-feature offset. In the fovea, horizontal and v...

We study theoretically the large variations of supercurrent through a normal dot that are induced by small quasiparticle injection current from leads connected to dot. find decomposes into subgap contribution, which depends on voltages applied leads, as well contribution with opposite sign energies outside gap, is insensitive voltages. As gradually suppress critical voltage exists above gap dom...

An investigation of the role of the proximity effect in current cross correlations in multiterminal, channel-mixing, normal-superconducting systems is presented. The proposed experiment is an electrical analog of the optical Hanbury Brown Twiss intensity cross correlation experiment. A chaotic quantum dot is connected via quantum point contacts to two normal and one superconducting reservoir. F...
