PROBLEM: Question: Does nitric acid passivation affect in vitro biocompatibility of titanium?
Answer: Although the protocol for passivation used here could interfere with the pattern of ions released from Ti-6Al-4V and cpTi surfaces, the present study did not show any effect of this surface treatment on in vitro biocompatibility of Ti as evaluated by osteoblast attachment, proliferation, and differentiation.

SOLUTION: no

PROBLEM: Question: Are enemas , suppositories and rectal stimulation effective in accelerating enteral feeding or meconium evacuation in low-birthweight infants : a systematic review?
Answer: Suppositories were ineffective in shortening the time to reach full enteral feeding, and the evidence on enemas was contradictory. Enemas and rectal stimulation did not shorten the time until complete meconium evacuation was reached. Further research into safe, effective interventions to accelerate meconium excretion is needed.

SOLUTION: no
