question:
Question: Does milrinone attenuate serotonin-induced pulmonary hypertension and bronchoconstriction in dogs?
Answer: We studied the effects of milrinone on serotonin-induced pulmonary hypertension and bronchoconstriction in dogs. Milrinone produces pulmonary vasodilation and bronchodilation, whose effects may not be caused by beta-adrenoceptor activation. In addition, this drug may be more sensitive to phosphodiesterase III in the airway smooth muscle than that in pulmonary vascular smooth muscle.
answer:
yes

question:
Question: Is a high body mass index in esophageal cancer patients associated with adverse outcomes following esophagectomy?
Answer: A high BMI is not associated with increased overall morbidity following esophagectomy; moreover, it is associated with decreased incidence of chylothorax. The better overall survival in patients with high BMI compared with those with low BMI might be due to a relatively low pathological stage. A high BMI should therefore not be a relative contraindication for esophagectomy.
answer:
no

question:
Question: Does the route of administration ( oral vs intravenous ) influence dose or outcome in Graves ' disease and unifocal autonomy?
Answer: The causes of individual differences between targeted and therapeutically achieved doses remain undetermined. Variations in the bioavailability of radioiodide or other parameters affecting thyroid status may be involved, and further investigations are needed to clarify this.
answer:
no
