TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Suppression of ghrelin production after Roux-en-Y gastric bypass that suggested its contribution to appetite reduction has been reported.', 'Because biliopancreatic diversion (BPD) does not affect appetite, we compared ghrelin production and 24-h pulsatility between healthy control subjects and obese subjects before and after BPD.', 'A computerized algorithm identified peak heights, clearance rate, and peak frequency of ghrelin over 24 h. Twenty-four-hour energy expenditure was measured in the calorimetric chamber, and energy intakes were computed. Insulin sensitivity was measured with a euglycemic-hyperinsulinemic clamp.', 'Mean (+/-SD) 24-h plasma ghrelin concentrations were significantly (P < 0.0001) higher in control than in obese subjects (338.17 +/- 22.09 and 164.47 +/- 29.19 microg/L, respectively), but they increased to 204.64 +/- 28.51 microg/L in the obese subjects after BPD (P < 0.01). The pulsatility index was 0.098 +/- 0.016 and 0.041 +/- 0.014 microg . L(-1) . min(-1) in control and obese subjects, respectively (P < 0.01), and decreased to 0.025 +/- 0.007 microg . l(-1) . min(-1) after BPD (P < 0.05). Energy intakes before and after BFP did not differ significantly. Although metabolizable energy after BPD was 40% of the energy intake, that (per kg fat-free mass) after BPD did not different significantly from that before BPD.'] Is ultradian ghrelin pulsatility disrupted in morbidly obese subjects after weight loss induced by malabsorptive bariatric surgery?
