Q: 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.

Q: Question: Does hyperoxia inhibit nitric oxide treatment effects in alveolar epithelial cells via effects on L-type amino acid transporter-1?
Answer: SNO uptake after NO treatment is dependent on LAT1. Hyperoxia impairs SNO uptake and NO effects during NO exposure and impairs LAT system function and LAT1 expression. Effects on SNO formation and transport must be considered for rational optimization of NO-based therapeutics.

A:
yes
