We propose a constructive approach to building single-hidden-layer neural networks for nonlinear function approximation using frequency domain analysis. We introduce a spectrum-based learning procedure that minimizes the difference between the spectrum of the training data and the spectrum of the network's estimates. The network is built up incrementally(More)
In order to evaluate if the assessment of the paradoxical GH responses to TRH in diabetic subjects could be altered by the presence of spontaneous fluctuations in plasma GH levels, we compared GH responses to TRH and to saline injection in 19 insulin-dependent diabetic patients. We observed significant increments (greater than 5 ng/ml) in plasma GH levels(More)
There is a decrease in the percentage contribution of a heavy density fraction of red blood cells to whole blood with increasing age. The aim of this study was to investigate in the young and elderly the interaction between monocytes and different erythrocyte suspensions: senescent red blood cells, erythrocytes stored with or without serum, and desialylated(More)
Systemic and local reactions to insulins in patients affected by insulin-dependent diabetes are uncommon but may be life threatening. Both systemic and local adverse reactions to therapy may be managed by different therapeutic schemes. The availability of human (DNA recombinant) insulin raised hopes that this be the choice treatment for allergic(More)
The aim of our study was to evaluate the acute effect of nifedipine, a calcium channel blocker, on exercise-induced microalbuminuria in normotensive and normoalbuminuric type 1 diabetic patients. Fifteen normotensive diabetic patients who were normoalbuminuric at rest (8 males and 7 females; age 16-35 years) and 10 normal subjects (6 males and 4 females;(More)
OBJECTIVES Adherence to insulin therapy can be threatened by pain and needle fear. This cross-over randomized non-inferiority trial evaluated a new Pic Insupen 33G × 4 mm needle vs. a 32G × 4 mm needle in terms of metabolic control, safety and acceptability in patients with diabetes treated with insulin. RESEARCH DESIGN AND METHODS We used a centralized,(More)
