Question: Question: Does exacerbation of headache during dihydroergotamine for chronic migraine alter outcome?
Answer: After controlling for nausea and other factors, headache exacerbation with DHE infusions is not an independent predictor of poor headache outcome and clinicians should not interpret its presence as a reason to stop treatment. The focus of management should be on controlling nausea as it is the most important modifiable factor in achieving a good headache outcome with an inpatient course of IV DHE for chronic migraine.

Answer: no

Question: Question: Is lipoprotein internalisation induced by oncogenic AMPK activation essential to maintain glioblastoma cell growth?
Answer: Our findings demonstrate that AMPK plays a crucial role in glioblastoma cell growth and suggest that blocking lipoprotein receptors could potentially be used as a plausible therapeutic approach for these and other type of tumours with high levels of AMPK.

Answer: yes

Question: Question: Are [ Continuous Svo2 measurements and co-oximetry interchangeable immediately after cardiopulmonary bypass ]?
Answer: Our results demonstrate that, in the immediate aftermath of cardiopulmonary bypass, the continuous measurement of SvO(2) and the co-oxymetry determination of mixed blood is not inter-changeable. Other studies will be necessary to confirm these results and enable us to understand the pathophysiological phenomena accounting for the lack of agreement between the two methods.

Answer:
no
