The objective of this study was to assess prospectively the frequency of near-death experiences (NDEs) in patients suffering a cardiac arrest, to characterize these experiences, and to assess their impact on psychosocial and spiritual attitudes. We prospectively evaluated all patients who suffered a cardiac arrest at Barnes-Jewish Hospital from April 1991(More)
We have identified a surface T3- Jurkat variant which has a defective alpha-chain but which possesses an intact beta-chain. The transfection of a functional mouse alpha-chain into this human T cell induces the expression of surface T3 molecules associated with mouse alpha-human beta-heterodimers detected by anticlonotypic antibodies. Treatment of the(More)
OBJECTIVE Our objective was to study the ability of three-dimensional MR angiography with retrospective respiratory gating to reveal stenoses in proximal coronary arteries on source and projection images. CONCLUSION Proximal coronary artery stenoses can be identified using three-dimensional MR angiography with retrospective respiratory gating, both with(More)
Forty patients ingesting tricyclic antidepressant (TAD) overdoses were studied as a pharmacologic model to determine whether total tricyclic antidepressant plasma levels correlated with major adverse effects and electrocardiographic findings. Maximum TAD plasma levels were higher in patients who died (p less than 0.025) or had cardiac arrest (p less than(More)
Fifteen patients were studied at 8- to 12-hr intervals during the first 24 hr after overdosing with tricyclic antidepressants, and subsequently followed daily for up to 144 hr. The severity of the overdose was determined by measuring the plasma tricyclic antidepressant level using gas chromatography-mass fragmentography. No correlation was found between(More)
The genes encoding the alpha and beta chains of the T-cell receptor (Ti) of an antigen-specific, Ia-restricted murine T-cell hybridoma were introduced into T3-positive or T3-negative human T cells. The resultant transfectants express either mouse-human or mouse-mouse Ti alpha beta molecules functionally associated with the human T3 complex. Only the(More)
was achieved at the end of infusion. Mean control A-V nodal conduction times (A-H: 99.5 -+34 msec) and A-H at peak PA levels (90 + 15.3) did not differ significantly. However, the mean infranodal conduction time (H-Q) at peak PA (68.1 + 14.8 msec) was significantly higher than control measurements (57.6 13 msec) (P < 0.001), with a mean percent increase of(More)
Bedside catheterization permitted 56 simultaneous measurements of left ventricular end-diastolic pressure (LVEDP) and pulmonary artery end-diastolic pressure (PAEDP) in 25 patients in shock. Measurements were made over a wide range of heart rates (60-160 beats/min), arterial oxygen tension (P02; 33-562 mm Hg), stroke volumes (9-105 ml), and systolic(More)
This study was designed to determine whether attenuation of ultrasound by myocardium is potentially useful in detecting and quantifying infarction. Accordingly, we analyzed 44 regions of myocardium from 11 dogs 4-10 weeks after coronary occlusion. Attenuation of ultrasound in each region was assessed by transmitting a broadband pulse through the tissue in(More)
