1. AproximaÃÃo espectral e construÃÃo de wavelets com aplicaÃÃes em eletrogastrografia / Spectrum approximation and wavelet design with applications in electrogastrography
Signal analysis is one of the most important areas of Signal Processing. This thesis is divided in three parts, each one addressing a specific topic of signal analysis. The sub-areas were: (i) approximate methods for spectrum evaluation; (ii) wavelet design; and (iii) biomedical signal analysis. The problem of spectrum estimation under constraints of minimal

2. Postprandial symptoms in dysmotility-like functional dyspepsia are not related to disturbances of gastric myoelectrical activity
Gastric dysrhythmias, such as tachy- or bradygastria, have been reported in patients with functional dyspepsia (FD), but their role in symptom production is uncertain. It is also not known whether gastric dysrhythmias in these patients can be elicited by physiological gastric distension with a meal. We investigated the relationships between symptoms after in

3. Delayed gastric emptying after Billroth I pylorus-preserving pancreatoduodenectomy: effect of postoperative time and cisapride.
OBJECTIVE: To study the recovery course of gastric emptying after Billroth I pylorus-preserving pancreatoduodenectomy (PPPD) and therapeutic effects of cisapride. METHODS: To examine gastric emptying, acetaminophen was given, admixed in a pasty liquid meal, to 16 patients undergoing PPPD before surgery and at 1, 3, 6, 9, and 12 months after surgery. Cisaprid

4. Normal gastric antral myoelectrical activity in early onset anorexia nervosa.
Anorexia, epigastric discomfort, nausea, and vomiting may result from disordered gastric motility and emptying. These features have been found in many adults with anorexia nervosa, but have never been investigated in early onset anorexia nervosa. In 14 patients with early onset anorexia nervosa (eight of whom had upper gastrointestinal tract symptoms), six c
