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: Does preinjury beta blocker usage affect the heart rate response to initial trauma resuscitation?
Answer: Preinjury beta blockade is associated with a slower presenting heart rate, more bradycardia, less tachycardia, but no difference in mortality or ability to achieve a normal heart rate with resuscitation.

Answer: no


Question: Question: Are insulin-like growth factor-binding protein 1 and 7 concentrations lower in obese pregnant women , women with gestational diabetes and their fetuses?
Answer: At the time of term cesarean section, pre-existing maternal obesity and GDM are associated with lower IGFBP levels in maternal and cord plasma. Alterations in circulating IGF and IGFBPs may alter birthweight and/or neonatal adiposity. This may lead to alterations in optimal growth trajectory and lead to metabolic disorders later in life.

Answer:
yes
