relative intelligibility of the cid spondees as presented via monitored live voice.	using three speakers and 75 subjects, a 7.90db range in the relative intelligibility of the central institute for the deaf (cid) spondees was found when they were presented via monitored live voice. this range is consistent with previous research and is considered unnecessarily large and detrimental to the efficiency and precision of the speech reception threshold (srt) test. the exclusive use of 18 words that have a mean range of 1.5 db is suggested. the slope of the 3l-item spondee articulatio ...	2002	1123931
the measurement of iron-binding capacity in serum and purified transferrin with the aid of chemical affinity chromatography.	in a mew method for the estimation of transferrin by iron-binding capacity iron is added as the tartrate in nacl with about 10 mm bicarbonate. the excess iron is removed by passage through deae-sephadex a-50 previously treated with the iron chelator disodium catechol-3,5-disulphonate. the iron remaining bound to transferrin is measured without protein precipitation by the use of ferrozine. the method is applicable to fresh, frozen, or lyophilized serum, purified transferrin, and some quality con ...	2005	1127111
an intergrative factor analysis of leadership measures and theories.	since the instruments for measuring most of the current leadership models have never been reconciled, it is important that the relationships between them be clearly understood before assumptions of similarity are made. a sample of 103 male working students were given a battery of tests measuring leadership orientations. the tests included role preference and role pressure measures from sweney's response to power model, the california f scale, fiedler's least preferred co-worker scale and assumed ...	2005	1151904
tunnel ulcer with double pyloric canal.	double pyloric canal produces a recognizable roentgen pattern. a split barium column at the pyloric canal results in an interposed pseudo-defect which must not be confused with tumor mass. the condition is usually caused by a tunnel ulcer extending from the distal stomach to the duodenal bulb and is probably more common than the small number of reported cases would suggest.	2005	1153732
compartmental evaluation of osteoarthritis of the knee. a comparative study of available diagnostic modalities.	the distribution and severity of osteoarthritis were investigated in 56 knees by history and physical examination, assessment of knee function, radiography with and without weight-bearing, double-contrast arthrography, and 99mtc-polyphosphate bone imaging. compartmental involvement (medial, lateral, patellofemoral) was graded independently by 2 or 3 observers for each modality and was correlated with that observed during arthroscopy or direct surgical inspection. the more involved compartments w ...	2005	1153764
antimicrobial resistance of shigella isolated in new york city in 1973.	one hundred and two shigella sonnei and fourteen s. flexneri strains isolated from individual patients in new york city hospitals were investigated for antibiotic resistance. the s. sonnei showed 60% resistance to ampicillin and 58% to tetracycline and streptomycin. s. flexneri showed no ampicillin resistance but 50% resistance to tetracycline. there were marked differences in resistance of s. sonnei between hospitals which were not explainable by ethnic or socio-economic differences in the pati ...	1975	1155925
time-dependent changes in commissural field potentials in the dentate gyrus following lesions of the entorhinal cortex in adult rats.	previous neuroanatomical work has shown that lesions of the entorhinal cortex in adult rats cause the commissural projections to spread from their normally restricted locus in the inner molecular layer approximately 40-50 mum into the outer molecular layer (that is, into the zone deafferented by the lesion). in the present study we measured the effects of the entorhinal lesion on the distribution of short-latency potentials elicited by commissural stimulation in the molecular layer. studies with ...	1975	1175043

in vitro repair of double-strand breaks accompanied by recombination in bacteriophage t7 dna.	a double-strand break in a bacteriophage t7 genome significantly reduced the ability of that dna to produce viable phage when the dna was incubated in an in vitro dna replication and packaging system. when a homologous piece of t7 dna (either a restriction fragment or t7 dna cloned into a plasmid) that was by itself unable to form a complete phage was included in the reaction, the break was repaired to the extent that many more viable phage were produced. moreover, repair could be completed even ...	1992	1309515
effects of professional and media warnings about the association between aspirin use in children and reye's syndrome.	the media played a central role in changing the use of aspirin among children with viral illness following reports of its association with a rare but deadly disease, reye's syndrome (rs). it did so by alerting health professionals and parents about ways to prevent rs in children. indeed, by the time aspirin product labeling was required by the fda in 1986, most of the decline in rs incidence had already occurred. in the past, media-only health education campaigns have been relatively unsuccessfu ...	2005	1316991
optimal stimulation of paralyzed muscle after human spinal cord injury.	muscle properties change profoundly as a result of disuse after spinal cord injury. to study the extent to which these changes can be reversed by electrical stimulation, tibialis anterior muscles in complete spinal cord-injured subjects were stimulated for progressively longer times (15 min, 45 min, 2 h, and 8 h/day) in 6-wk intervals. an index of muscle endurance to repetitive stimulation doubled (from 0.4 to 0.8), contraction and half-relaxation times increased markedly (from 70 to approximate ...	1992	1317372
