Q: Question: Does insulin , unlike food intake , suppress ghrelin in human subjects?
Answer: Unlike food intake, the administration of insulin and glucose does not suppress ghrelin levels. These data suggest that the suppressive effect of food intake or oral glucose on serum ghrelin is unlikely mediated by the changes of plasma insulin and glucose observed after the ingestion.

A: no

Q: Question: Does intracanal delivery of Resolvin E1 control inflammation in necrotic immature rat teeth?
Answer: RvE1 and TAP had a positive impact on reducing inflammation and promoting root formation. RvE1 was more effective in reducing inflammation at earlier stages. RvE1 has potential to be used as root canal dressing to control inflammation in endodontically compromised teeth before complete root formation. Stability of RvE1 within the root canal and its delivery are issues to be addressed before its clinical use.

A: yes

Q: Question: Do residency program director evaluations correlate with performance on a required 4th-year objective structured clinical examination?
Answer: We concluded that program director evaluations of resident performance do not appear to correlate with objective tests of either clinical skills or knowledge taken during medical school. These findings suggest that more structured and objective evaluative tools might improve postgraduate training program assessment of trainees.

A:
no
