question:
Question: Does metoclopramide influence the frequency of propofol-induced spontaneous movements?
Answer: Metoclopramide does not affect the frequency of propofol-induced movements, but propofol and fentanyl doses influence the frequency of movements during propofol induction.
answer:
no


question:
Question: Do differential behavior patterns in cynomolgus monkey Macaca fascicularis in home cage in response to human gaze?
Answer: These results indicate that, even in their home cage, monkeys display a heightened level of awareness when gazed upon by a human observer, suggesting that human gaze may elicit emotional reactions. Further, under the human gaze, distinct behavioral subpatterns were apparent within the monkey cohort in our study, indicative of subgroups within the cohort.
answer:
yes


question:
Question: Is response to methotrexate in early rheumatoid arthritis associated with a decrease of T cell derived tumour necrosis factor alpha , increase of interleukin 10 , and predicted by the initial concentration of interleukin 4?
Answer: During treatment of RA with MTX the percentage of TNFalpha producing T cells decreases whereas that of IL10 producing T cells increases. This may affect macrophage activation and, therefore, may represent a regulatory mechanism relevant to disease remission. Furthermore, the percentage of IL4 positive CD4(+) T cells at disease onset may be a useful prognostic marker.
answer:

yes
