In order to evaluate the source and course of gastrointestinal bleeding in patients with established renal insufficiency, we reviewed data on 40 patients with renal failure and gastrointestinal bleeding seen over 2 yr. A randomly selected control group of 39 patients without renal failure was used for comparison. Medical records of our University Hospital(More)
The role of stimulus uncertainty in backward masking was investigated using a Monaural Detection with Contralateral Cueing (MDCC) paradigm. Cues temporally synchronous with and phase locked to the signal (20-ms segment of 500-Hz sinusoid) reduced backward masking, with the amount of reduction being independent of the phase relationship between the cue and(More)
In this study, to model 3D chemotactic tumor-stroma invasion in vitro, we developed an innovative microfluidic chip allowing side-by-side positioning of 3D hydrogel-based matrices. We were able to (1) create a dual matrix architecture that extended in a continuous manner, thus allowing invasion from one 3D matrix to another, and (2) establish distinct(More)
Two-channel auditory signal detection was investigated with 50-msec sinusoidal signals masked by binaurally uncorrelated noise. In the two-channel tasks, the signals in each earphone channel were presented with an independent probability during the single observation interval and the observers were required to detect the inputs in a single earphone(More)
In 1974 Wood proposed a hybrid serial-parallel model to account for the within-stimulus interactions between the acoustic cue of "pitch" and the phonetic cure of "place." Three of the five experiments in this paper replicate the Wood findings with analogous, clearly nonphonetic stimuli and thus refute Wood's implicit assumption of the involvement of any(More)
An epidemic due to Pediculus humanus capitis occurred in the public schools of Buffalo, New York, in the winter of 1973. A survey at one elementary school showed that 20% of whites and no blacks were infested, and a city-wide prevalence survey during the academic year September 1972 to May 1973 showed that 7.2% of all pupils were infested. An(More)
Complex reaction time (RT) was measured for a task in which a discriminative auditory cue designated whether the right or left hand was to be used in responding. Facilitation of monaural RT compared to binaural RT occurred on trials in which both (1) the ear stimulated corresponded to the hand specified for response and (2) each of 20 male college students(More)
This report describes the successful treatment of totally occluded aortocoronary saphenous vein grafts with percutaneous transluminal extraction atherectomy (TEC) in three patients with severe angina and high reoperative surgical risk. The method presented here may provide an alternative to overnight urokinase infusion or repeat surgery in high risk(More)
