Such an early-stage analysis highlights the main bottlenecks that need to be solved in developing a sustainable bioprocess. Alfaxalone has been used increasingly in biomedical research and veterinary medicine of large animals in recent years. However, its effects on the cerebral blood flow (CBF) physiology and intrinsic neuronal activity of anesthetized brains remain poorly understood. Four healthy adult rhesus monkeys were anesthetized initially with alfaxalone (0.125mg/kg/min) or ketamine (1.6mg/kg/min) for 50min, then administrated with 0.8% isoflurane for 60min. Heart rates, breathing beats, and blood pressures were continuously monitored. CBF data were collected using pseudo-continuous arterial spin-labeling (pCASL) MRI technique and rsfMRI data were collected using single-shot EPI sequence for each anesthetic. Both the heart rates and mean arterial pressure (MAP) remained more stable during alfaxalone infusion than those during ketamine administration. Alfaxalone reduced CBF substantially compared to ketamine anesthesia (grey matter, 65±22 vs. 179±38ml/100g/min, p<0.001; white matter, 14±7 vs. 26±6ml/100g/min, p< the monkey brain.The residual effect of alfaxalone on CBF of isoflurane-exposed brains was evident and monotonous in all the examined brain regions when used as induction agent for inhalational anesthesia. In particular, alfaxalone showed similar suppression effect on intrinsic neuronal activity of the brain in comparison with ketamine. These findings suggest alfaxalone can be a good alternative to veterinary anesthesia in neuroimaging examination of large animal models. However, its effects on CBF and functional connectivity should be considered.1-Methyl-4-phenylpyridinium ion (MPP+)-induce
