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)
BACKGROUND The aim of this prospective, multicenter study was the identification of Doppler flow velocity measurements predictive of clinical outcome of patients undergoing single-vessel balloon angioplasty with no previous Q-wave myocardial infarction. METHODS AND RESULTS In 297 patients, a Doppler guidewire was used to measure basal and maximal(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)
Vitamin D is required for calcium homeostasis and bone metabolism. This prospective observational study examined the incidence of vitamin D deficiency amongst patients with a fracture of the femoral neck, and the correlation between pre-admission use of bone-protection medication and vitamin D levels. Vitamin D assays were available in 75 out of 151(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)
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)
STUDY OBJECTIVE The aim was to examine the value of a subthrombolytic maintenance infusion of recombinant double chain tissue plasminogen activator (BW t-PA, Duteplase) in preserving microvascular coronary flow following initial thrombolysis. DESIGN Coronary arterial thrombi were induced by a copper coil (placed under fluoroscopic control) in the canine(More)
Beta-sitosterol is the most prevalent plant cholesterol derivative (phytosterol) and can undergo similar oxidation to cholesterol, leading to beta-sitosterol oxides. The biological impact of phytosterol oxides has only been evaluated in a phytosterol blend (usually of beta-sitosterol, campesterol, stigmasterol and dihydrobrassicasterol). The lack of pure(More)
As α-carboxy nucleoside phosphonates (α-CNPs) have demonstrated a novel mode of action of HIV-1 reverse transcriptase inhibition, structurally related derivatives were synthesized, namely the malonate 2, the unsaturated and saturated bisphosphonates 3 and 4, respectively and the amide 5. These compounds were evaluated for inhibition of HIV-1 reverse(More)
