BACKGROUND Although their assessment could be of the utmost importance to determine the surgical treatment for patients with univentricular hearts, differences in ventricular performance between partial and complete right heart bypass remain to be defined. METHODS Three different degrees of right heart bypass were investigated in 5 mongrel dogs: (1)(More)
1. Whole soluble venom from the snake Crotalus durissus terrificus was detoxified by controlled iodination. Doses equivalent to 100 LD50 of the native venom were administered to mice, without signs of intoxication. 2. The non-toxic iodinated derivatives were able to stimulate antibodies in rabbits and horses within a short period (6 months) of immunization.(More)
There is still controversy about the optimal method of venoarterial cardiopulmonary bypass (CPB) for correction of congenital heart disease in neonates and young infants. High rates of CPB-related morbidity and mortality are still reported. Since 1980, conventional CPB with double caval cannulation with right-angled cannulae has been used in the high(More)
Introduction: Nocardia are gram positive, variably acid­fast positive diphtheroidlike to branched, filamentous, aerobic actinomycetes. Nocardiosis is an opportunistic infection that has been noted in patients with malignancies, systemic lupus erythematosus, HIV infection, hematopoietic stem cell transplant recipients and long­term steroid users.

The iodination of the T2 fraction abolished its lethal capacity, and doses up to 30 times the LD50 were injected i.p. in mice without noticeable toxic effects. The modified fraction retained its immunological properties. Antibodies generated against the iodinated T2 fraction were also reactive toward the native T2 fraction, T1 fraction and the whole soluble(More)
Immediate and long-term results of the Fontan procedure depend on the value of the pulmonary vascular resistance. This parameter cannot always be quantified accurately during preoperative evaluation. Cavo-pulmonary bypass using an extra corporeal circulation allowed simulation a Fontan procedure in 5 patients, and prediction of the pressure changes in the(More)
