OBJECTIVES The application of molecular tests to thyroid fine needle aspiration (FNA) has been shown to be a valuable tool to better refine the pre-operative malignant risk of patients with indeterminate cytology results. In this study, we investigated the feasibility of using the laser capture microdissection (LCM) technique to obtain DNA and RNA for(More)
Thyrotoxicosis is associated with increased cardiovascular morbidity and mortality, primarily due to heart failure and thromboembolism. Palpitations, caused by sinus tachycardia and occasionally by atrial fibrillation, are the most frequent cardiovascular symptom. As atrial fibrillation may be the only manifestation of thyrotoxicosis, thyroid hormone excess(More)
Three enzymes intervening in de novo purine synthesis, as well as cystathionine B-synthetase, have been mapped to chromosome 21. In order to gain a better understanding of purine synthesis anomalies in Down's syndrome, the present authors studied the variations in mitotic index of lymphocyte cultures to which various inhibitors or metabolites of purine(More)
The relative concentrations of plasmatic and urinary amino acids were analysed in 79 trisomic-21 patients, 322 mentally retarded non-trisomic patients, and 206 controls. No true amino acidopathy was found in 21-trisomy, but in plasma a deficit of serine and an excess of cysteine and lysine are highly significant. Excesses of cysteine, methionine, tyrosine,(More)
Having previously demonstrated that patients with cri du chat, 5p- syndrome, have a highly significant excess of the plasmatic and urinary relative amount of asparagine and aspartate, the authors tested the hypothesis according to which this excess could be in relation with a defect of purine metabolism. Using a previously reported in vitro assay, they(More)
