Question: Question: Is translation of questionnaires measuring health related quality of life standardized : a literature based research study?
Answer: This study shows that there seems to be a consensus regarding the translation process (especially for internal validity) although most researchers did not use a translation guide. Moreover, we recommended that clinical researchers should consider three steps covering the process of translation, the qualitative validation as well as the quantitative validation.

Answer: no


Question: Question: Do xenon and nitrous oxide depress cardiac function in an isolated rat heart model?
Answer: Our data suggest that cardiac contractility was decreased by the effects of reduced O2 delivery, but both Xe and N2O did not cause further cardiac depressant effects compared to N2 in this experimental model.

Answer: no


Question: Question: Does melatonin Receptor 1-Deficiency affect Feeding Dynamics and Pro-Opiomelanocortin Expression in the Arcuate Nucleus and Pituitary of Mice?
Answer: Thus, the MT1-mediated signaling stimulates Pomc expression in a region-specific pattern. Since the MT1 mediated changes in Pomc expression do not elicit direct orexigenic or anorexigenic effects such effects are obviously mediated by regulatory systems downstream of the POMC mRNA (e.g. cleavage and release of pro-opiomelanocortin derivatives) which are independent of MT1 signaling.

Answer:
yes
