Preterm infants fed formulas with docosahexaenoic acid (DHA, 22:6n-3) during the interval equivalent to the last intrauterine trimester and beyond have higher circulating DHA and transiently higher visual acuity compared with infants fed formulas containing linolenic acid. In term infants several nonrandomized studies of infants receiving DHA from human(More)
Phytosterols are plant sterols found in foods such as oils, nuts and vegetables. Phytosterols, in the same way as cholesterol, contain a double bond and are susceptible to oxidation. The objective of the present study was to assess the potential toxic effects of beta-sitosterol oxides on U937 cells. The effects of increasing concentrations (0-120 microm) of(More)
Our purpose was to examine postnatal growth in very low birth weight (VLBW) infants (n = 54). A high frequency of intrauterine growth retardation was noted that was corrected by plotting birth weight against crown-heel length and not gestational age. No differences in postnatal growth were noted between infants whose size was appropriate for gestational age(More)
A newly developed, flow-directed, Doppler pulmonary artery catheter, capable of measuring instantaneous and continuous cardiac output, was evaluated in both an in vitro pump model and an animal model. Quantitative flow was calculated with use of the instantaneous, space-average velocity (obtained from the velocity profile) and the instantaneous area(More)
A new Doppler pulmonary artery catheter was used to measure instantaneous and continuous cardiac output in both an in vitro model and in 44 patients undergoing cardiac catheterization. Cardiac output was calculated with use of the Doppler catheter-determined instantaneous space-average velocity and the ultrasonically determined instantaneous vessel area.(More)
The novel compound BW A575C, N-(1-(S)-carboxy-5-[4-(3-isopropylamino-2-(R,S)-hydroxypropoxy)-indole-2 - carboxamido]pentyl)-(R,S)-alanyl-(S)-proline, is a potent angiotensin converting enzyme (ACE) inhibitor and beta-blocker in vitro. It was therefore of considerable interest to establish whether this novel pharmacological profile was maintained in vivo. In(More)
A canine model suitable for serial conscious studies was developed to evaluate the nature of sustained ventricular tachyarrhythmias in chronic experimental myocardial infarction. Thirteen dogs underwent left anterior descending coronary artery ligation followed by complete reperfusion; 11 sham-operated dogs served as controls. In this model, ventricular(More)
An improved procedure for the synthesis of N-benzoyl-2',3'-O-isopropylidene uridine via one-step selective N-benzoylation of 2',3' -O-isopropylidene uridine has been developed. An efficient synthetic route to N-benzoyl thymidine via initial tribenzoylation, followed by selective hydrolysis of the benzoates is also described. De-N-benzoylation of(More)

STUDY OBJECTIVE The aim was to evaluate the thrombolytic efficacy of recombinant double chain tissue plasminogen activator (Duteplase, t-PA) given as a single intravenous bolus versus an infusion in a canine model of coronary arterial occlusion/reperfusion. DESIGN Coronary arterial thrombi were induced by a copper coil (placed under fluoroscopic control)(More)
