[Study of malignant melanoma using 1H-nuclear magnetic resonance spectroscopy].

1H-nuclear magnetic resonance spectroscopy was used to study malignant melanoma extract. The aim of this work was to study low molecular weight metabolites soluble in water, which can be helpful for a more detailed understanding of tumor metabolism with a view to using this knowledge for diagnosis. The authors found in a well distinguished spectrum the presence of numerous low molecular weight metabolites such as glutamate, glutamine, choline, inositol, creatine, phosphocreatine, phosphocholine, glucose, acetate, alanine, lactate.

[Atrioventricular valve replacement in congenital cardiopathies. A series of 25 surgically-treated patients under 10 years of age].

A series of 25 congenital malformations of the atrioventricular valves underwent valve replacement (10 mechanical and 15 bioprostheses). Seven children died during surgery. The operative mortality was higher before 2 years of age (4/7) than in older children (3/18).
