PROBLEM: Question: Is unexplained elevated maternal serum alpha-fetoprotein predictive of adverse perinatal outcome in an indigent urban population?
Answer: Elevated maternal serum alpha-fetoprotein levels offer little if any additional predictive value for adverse perinatal outcome in populations already at high risk for such outcomes on the basis of obstetric or socioeconomic criteria.

SOLUTION: no

PROBLEM: Question: Does prolonged hemorrhagic shock impair regeneration of plasma coagulant masses in the rabbit?
Answer: Dilutional coagulopathy corrects spontaneously within hours. Normovolemic shock prolongs dilutional coagulopathy not by impairment of factor regeneration but because of further (internal) dilution due to plasma expansion. Rapid correction of dilutional coagulopathy is likely to necessitate cryoprecipitate administration.

SOLUTION: no

PROBLEM: Question: Do insulin resistant rats display enhanced rewarding effects of nicotine?
Answer: These present study suggests that insulin resistant rats undergo unique neurobiological changes related to a disruption in insulin signaling that promotes the rewarding effects of nicotine.

SOLUTION:
yes
